They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong numbers 无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The

I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 我公司投资的10万吨糖蜜酒精，用甘蔗汁为原料产生废糖蜜经过发酵生产酒精，在生产酒精的过程中产生高浓度有机废水。酒精废水未经处理就近排入水体，会造成一定程度的污染，因此，必须建设配套的污水处理设施。

I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst.

He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag.

The Referring to the molasses alcohol parameters of the same type manufacture factories and the determined wastewater value, the design is as follows:
CODcr ≤80000mg/l（before plate and frame filter press） CODcr ≤45000mg/l（after plate and frame filter press）
BOD5 ≤25000mg/l SS ≤5000mg/l

第三节 污水处理程度的确定
Section Three Wastewater treatment level
污水处理工程对污水中主要污染物的处理程度是确定处理工艺的基本依据。而处理程度主要依据污水处理厂出水受纳水体的水体标准和环境容量，依照国家颁布的有关排放标准来确定根据《中华人民共和国污水综合排放标准》（GB8978—1996），排入该水体的污水执行二级标准，即污水处理站的出水水质应达到：
In the wastewater treatment project, the disposal level for the main pollutants in
wastewater is the basic criterion to design the process. The disposal level depends on the receiving water body of water standards and environmental capacity. In accordance with \Republic of Integrated Wastewater Discharge Standard\effluent standards for wastewater discharged in the water body, that is, effluent water from wastewater treatment plant should meet the following quality:
CODcr ≤300mg/l BOD5 ≤150mg/l SS ≤200mg/l
PH ： 6-9 NH3—N ≤25mg/l 根据进水水质和出水水质的要求，显然简单的机械处理不能满足要求，因此本工程将采用厌氧—好氧生物处理的方式以达到上述要求。
According to the requirements of inlet and outlet water quality, apparently simple mechanical
processing cannot meet the requirements of this project. Therefore, anaerobic + aerobic process is adopt to meet above requirements.
第三章 污水处理工艺的确定
Chapter Three Wastewater treatment process
第一节 处理工艺选择
Section One Treatment process
污水处理工艺的选择直接关系到出水水质指标能否达到要求，关系到运行是否稳定可靠，管理是否方便以及投资和运行成本的高低。因此，慎重选择适当的处理工艺是污水处理设计的关键。
The choice of wastewater treatment process will directly affect to the outlet water quality, steadily running, management, investment and operation cost. Therefore, careful selection of appropriate treatment technology is the key for wastewater treatment.

'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth.

I live near an airport and passing planes can be heard night and day. The 糖蜜酒精废水是高浓度、高温度的有机废水，因此简单的机械和物化的方法不能保证污水处理的稳定达标排放，高浓度有机废水如果直接进行好氧处理，势必会造成能耗过高，从而增加污水处理的运行成本，而单独的厌氧处理也不能直接达标排放。
因此，本污水处理工程采用厌氧+好氧的处理方法。
The molasses alcohol wastewater is organic wastewater with high concentration and high temperature. So simple mechanical and physic-chemical method cannot guarantee the qualified discharge of wastewater. If directly use aerobic treatment for high concentrated organic wastewater, it will lead to high cost. And the anaerobic treatment alone cannot reach the requirement either.
Therefore, the wastewater treatment project adopts anaerobic + aerobic treatment.
一、厌氧工艺的选择 / Anaerobic process
目前应用于高浓度废水处理成熟的厌氧方案主要有UASB和BIC,因此针对这两种厌氧工艺进行比较如下：
At present, there are two kinds of mature process, UASB and BIC, to dispose the high concentrated wastewater. therefore, compare the both processes as follows:
（一）UASB厌氧反应器 / UASB anaerobic reactor
UASB即为上流式厌氧污泥床反应器，为第二代厌氧反应器的典型代表。整个反应器主体可分为两个区域：反应区和气、液、固三相分离区。污水通过水泵提升到厌氧反应器的底部，利用底部的布水系统将污水均匀地布置在整个截面上，同时利用进水的出口压力和产气作用，使废水与高浓度的厌氧污泥充分接触和传质，将废水中的有机物降解。废水在反应区缓慢上升，进一步降解有机物。气体、水、污泥在
沼气 同时上升过程中，沼气首先进入三相分离器内部通过管道排出，污泥和废水通过三相分离器的缝隙上升到分离区，污泥在分离区沉淀浓缩并回流到分离三相分离器的下部，保持厌氧反应器区 出水 内的生物量，沉淀后的出水通过管道排出罐外。
三相分离器 sludge UASB is up-flow anaerobic
blanket reactor, it is the typical
反representative of the second 应区 generated anaerobic reactor.
The whole reactor can be divided
布水系统 zone into two regions: reaction
and three-phase
separation zone of gas, liquid
进水 and solid. Upgrade the wastewater to the bottom of anaerobic reactor by water UASB反应器结构示意图 pump, distribute the
wastewater on the whole section by use of water distributor, meanwhile, utilize the outlet

After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong numbers 无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered.

I live near an airport and passing planes can be heard night and day. The pressure and aerogenesis to make wastewater and high concentrated anaerobic sludge have enough contact and mass transfer, and finally degrade the organic matter in wastewater. The wastewater slowly rise in the reaction zone and further degrade the organic compounds. In the ascent process of gas, water and sludge, the biogas first enter the three-phase separator and then discharge through pipeline, meanwhile, the sludge and wastewater upgrade to the separation zone through the gap. The sludge concentrate and return back into the down part of three-phase separator to keep the biomass in anaerobic reactor, and the water after precipitation drainage through pipe.

Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 废水中的有机物进行精处理。
② Low load area: It is polishing unit, in which area, the hydraulic load and sludge load is lower. So the organic matter will be effectively removed from the wastewater.
③沉降区： BIC反应器顶部为污泥沉降区，有机物已基本去除，废水中的少量悬浮物在本区内进一步进行沉降，保证BIC出水水质。
③ Settlement area: The top area of BIC reactor is settlement area. The organic matter has been basically removed and small amount suspended matter in wastewater will have further settlement, which ensures the BIC outlet water quality.
④基本原理：废水通过布水系统进入厌氧反应器的下部高负荷区，与颗粒污泥进行充分的混合和传质，将废水中大部分的有机物分解，产生大量的沼气。沼气通过提升装置时，由于沼气的提升作用，沼气连同一部分混合液被提升到罐顶部的气液分离器，沼气在气液分离器里被分离出来，分离后的混合液再通过回流管回流到罐的底部，与进入BIC厌氧反应器的进水混合，形成了厌氧罐自身的内循环。
④ Basic principle: The wastewater enters into the high load area in anaerobic reactor bottom through water distribution system. The wastewater and granular sludge have adequate mixture and mass transfer, upgrade the organic matter and bring out biogas. The biogas and part of the mixed liquor is taken up to the gas-liquid separator, where the biogas is separated and the mixed liquor reflows to the tank bottom and blend with the inlet water of BIC anaerobic reactor. It forms the self internal circle of anaerobic tank.
废水通过提升装置后进入上部低负荷区（精处理区），进一步降解废水中的有机物，混合液通过上部的三相分离器时进行颗粒污泥、水、沼气的分离，沼气通过沼气管道排出，污泥则回流到厌气罐底部保持生物量，而沉淀后的水通过出水堰进入后续构筑物。
The wastewater gets into the up part low load area to degrade the organic matter for further. The mixed liquor separates the granular sludge, water and biogas by three-phase separator. The biogas discharge from the biogas pipe and the sludge reflow to the anaerobic tank bottom to keep the biomass.
BIC运行成功的关键因素是必须用颗粒污泥接种，以下是我公司在工业废水中培养的颗粒污泥。
The key for BIC running is using granular sludge to inoculate. The below is granular sludge brought up by our company.
Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back.

② As for the organic load, the BIC is higher than UASB, thus, treating the same capacity
wastewater, the volume of BIC reactor is smaller than UASB. In another word, the BIC reactor will take smaller room.
③ 废水中的CL-、SO42-等可能会对厌氧处理有毒性。在UASB中污泥与废水混合不匀，将导致部分污
Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 7

I live near an airport and passing planes can be heard night and day. The 泥受到毒性抑制；而在BIC反应器内，由于大的内循环作用使污泥与废水充分混合，能最大程度的释
稀可能的毒性，降低其抑制作用。
③ The CL- and SO42- in wastewater may be harmful to the anaerobic treatment process. In the
UASB, uneven mixture for sludge and wastewater will lead to toxic inhibition for part of sludge. But in the BIC reactor, big internal circle result in the fully mix for sludge and water, which will crack the toxic as possible and reduce the inhibitory effect.
④ 进水浓度的突然增加或进水量的突然加大，都会对厌氧反应器造成负荷冲击，BIC因其内循环作用，
瞬间的高浓度废水进入反应器后，产气量大，气提量会随着增大，从而内循环量大，大的内循环量能将高浓度的废水迅速的释稀，从而减少了有机负荷变化对反应器的冲击。UASB反应器则不然，有机负荷突然增大后，迅速增加的产气量会将污泥带出反应器，严重时会造成恶性循环，导致整个反应器失败。
④ The sudden increase for inlet water concentration or capacity will result in load impact for
the anaerobic reactor. Because of the internal circle action, at the moment of wastewater entering the BIC, the gas output will increase. The big circulating load will dilute the high concentrated wastewater quickly and reduce the impact to the reactor. The UASV reactor is different. When the organic load suddenly increased, the increased gas output will bring sludge out of the reactor. Seriously, it will cause vicious circle or failure for whole reactor.
⑤ 高的水力负荷和多旋流式的布水能最大程度的保证布水均匀，UASB大多采用的是多点式布水，并且
水力负荷较低，因此布水均匀性不如BIC。
⑤ High hydraulic load and multi-cyclone water distribution will maximum ensure the equally
water distribution. The UASB mostly use multipoint water distribution, which has low water load. Therefore, the BIC is better than UASB.
⑥ 因为内循环的原因，BIC上下反应区具有不同的水力负荷，下反应区具有较高的上升流速，保证了废
水与污泥的传质与混合，而上反应区的较低的上升流速，又保证了污泥的沉降不会受到大的影响，UASB反应器的上升流速大于1m/h时，会极易造成污泥的流失。
⑥ Because the reasons of cycle, BIC reaction zone has different hydraulic load for upside and
downside. The downside has higher up flow rate, ensuring the mass transfer and mix for wastewater and sludge. The upside has lower up flow rate, ensuring the sludge settlement without huge affect. If the up flow rate if UASB reactor exceeds 1m/h, the sludge will lose.
⑦ BIC多旋流式布水采用了少量的大口径布水管，出口流速可以达到3-5m/s以上，可以有效的防止结垢
和堵塞。
⑦ BIC cyclone water distribution adopts large-diameter pipes, with the flow rate over 3-5m/s. It can effectively prevent fouling and plugging.
根据上述的工艺比较，结合废水从生产车间的流量、水质不稳定，对废水处理设施冲击大的特点，选用BIC厌氧反应器作为厌氧处理工艺。
According to above comparison, combined with instability of wastewater flow volume and quality, as well as the big impact on the water treatment facilities, select BIC anaerobic reactor as anaerobic treatment process.
二、好氧工艺方案的选择 / Aerobic process

Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong numbers 无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately.

I live near an airport and passing planes can be heard night and day. The 酒精废水中含有大量的蛋白质类物质，这些物质经厌氧分解后转化为氨氮。因此，厌氧出水中含有浓度较高的氨氮，故后续的处理不能采用常规工艺，须用带有脱氮功能的工艺。 本工程中采用A/O法作为好氧脱氮处理工艺。
The alcohol wastewater contents a lot of protein matter, which will transfer into NH-N after anaerobic decomposition. Therefore, the outlet water of anaerobic process contents high
concentrated NH-N. That means, the following treatment shall not adopts routine process but process with denitrifying function. This project use A/O technique to denitrify the N.
第二节 工艺方案的确定 Section Two Process plan 一、工艺流程 / Process flow
综上所述，确定本污水处理工艺为厌氧采用BIC厌氧反应器，好氧采用A/O活性污泥法。
In sum, the wastewater treatment process determines to use BIC reactor for anaerobic and A/O active sludge process for aerobic.
废水处理工艺流程图见附件：
The wastewater treatment flow chart is as attached file.
二、工艺简介/ Process brief
车间过来的酒糟水含有大量的糟渣，首先进入脱水机房进行脱糟处理，脱出来的糟渣外运。
There are many grains contained in spent wash from the workshop. First carry out the dehydration proposal and then out transport the slag.
脱糟后的废水自流进入调节池，调节废水的水质水量等，然后通过提升泵到BIC，同时进入BIC的还有一沉池回流水，在BIC内利用厌氧菌将废水中的有机物分解成甲烷、二氧化碳等气体，去除废水中的大部分有机物。
The wastewater flow to the regulate pond to adjust the water quality and quantity. Then it is pump to the BIC, as well as the reflow water from the first sedimentation tank. In the BIC, the anaerobic organism degrade the organic matter into CH4, CO2 and other gas. Most of the organic matter is released.
经过厌氧反应器（BIC）处理后的水自流到一沉池，一沉池出水一部分回流到BIC，剩余的水进入接触氧化池把水中大部分有机物去除，出水进入后续的A/O池，在A/O池内的好氧微生物将废水中剩余的有机物氧化分解，同时将大部分氨氮转化为氮气去除，氧化池出水自流到二沉池，二沉池沉淀的污泥一部分回流到A/O池，上清液达标排放。
Water out of the anaerobic reactor ( BIC ) treatment partly flows to the first sedimentation, the first sedimentation water outlet partly reflow to the BIC, the other water enters the contact oxidation pool to remove most of the organic matter, at the same time, transfer NH-N into N2 and remove it. The outlet water of oxidation pool flows to the secondary sedimentation, where the sludge partly return to A/O. The supernatant will be discharged when reaches the mark.
污泥主要来自BIC厌氧反应器、一沉池污泥、二沉池剩余污泥。污泥先排到污泥池，再到污泥浓缩池进行浓缩，然后送到脱水机脱水后外运。

Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late为时太晚 The plane was late and detectives were waiting at the airport all morning.

It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681.

It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all.

Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket.

This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me.

'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The The sludge is mainly from anaerobic reactor, first and secondary sedimentation.

This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket.

二、BIC厌氧反应器 / BIC anaerobic reactor
废水从调节罐由泵提升至厌氧反应器内进行厌氧发酵：利用厌氧微生物在厌氧和适宜的温度及PH条件下，分解废水中的有机物，产生CH4、CO2、水和少量的其它气体，使高浓度的有机废水得以初步净化。
The wastewater from regulating pool is upgraded by pump to the anaerobic reactor to carry out anaerobic fermentation. Make use of anaerobic micro-organisms in the conditions of anaerobic, appropriate temperature and PH to decompose organic matter in wastewater and product CH4, CO2, water and a small number of other gases, so that high concentrations of organic wastewater is initially purified.
厌氧罐采用BIC厌氧反应器，它能够适应高浓度有机废水的负荷冲击。废水由水泵送到厌氧罐底部的布水系统，与从气液分离器回流来的水混合，由于大量的回流水和高的产气负荷，混合水经过罐底部的颗粒污泥层时，能与颗粒污泥进行充分的混合和传质，使厌氧菌分解有机物始终保持很高的效率。产生的气体则通过罐内中部的三相分离装置将气体、一部分水利用沼气的提升作用输送到罐顶部的气水分离装置，沼气通过水封送到沼气发电机组，分离水由管道自动回流到罐内底部，从而形成内循环；经过下三相分离器废水继续上升进入上部的精处理区，进一步降低废水中的有机物。
Anaerobic tank adopts BIC anaerobic reactor, which can adapt to the impact load of high concentration organic wastewater. The wastewater is send to the water distribution system on
bottom of anaerobic tank by water pump and mixed with water returned from gas-liquid separator. Because of the returned water and high gas load, when passing the tank bottom layer, the mixed water will adequately mix and mass-transfer with granular sludge to keep the anaerobic decomposition of organic matter maintaining high efficiency. Passing through three-phase
separator in the tank middle part, the gas and part water make use of the upgrading of methane and transport to the water separation devices on top of the tank. The methane is discharged or used by water seal, and the separated water automatically flow back to the tank bottom along pipeline. Therefore, the internal circulation is brought out. Through the bottom three-phase
separator, the wastewater continues to rise into the upper essence treatment part to reduce the organic matter in waste water for further.
废水在厌氧发酵时最适宜的温度有中温（36±2℃）或高温（53±3℃），应根据该废水性质，选择高温厌氧发酵。
The suitable temperature for wastewater in anaerobic fermentation is middle temperature (36 ± 2 ℃) or high temperature (53 ± 3 ℃). It should base on the wastewater and select the appropriate anaerobic fermentation temperature.
厌氧菌中的产甲烷菌最适宜生长的PH值在6.8-7.2之间，而该类废水的PH值在6-7之间，因为废水进入厌氧罐后由于罐内废水的稀释作用和微生物作用，几乎瞬间就跟厌氧罐内的PH环境一至，而不用调节进水的PH值。
The suitable growth PH value of methanogen in anaerobe is between 6.8-7.2. For the
wastewater after adjustment, the PH value is between 4.5-6. When the wastewater entering the anaerobic tank, there is no need to adjust the inlet water PH value because by the dilution and

After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing.

It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all.

Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The Main equipment: half-bridge scraper

五、接触氧化池 / Contact oxidation tank
在A/O好氧池前设接触氧化池目的是将大部分有机物在这里去除，保证A/O好氧池中硝化池（好氧池）污泥中硝化菌的含量。因为硝化池内含碳有机基质的浓度太高，会使生长速率较高的非硝化菌过度繁殖，从而使硝化菌得不到优势，降低了硝化速率影响脱氮效果。
The reason to put contact oxidation pond before A/O aerobic pool is to remove most organic and ensure the nitrobacteria content in the sludge. If the concentration of carbon organic
substrate in nitrification pond is high, it will lead to the over speed propagation of non-nitrified germ with high growth speed. So that the nitrobacteria will lost its advantage, reduce the nitrification rate and affect the result.
接触氧化法是生物膜法的一种，它由池体、填料、曝气系统组成，由于池内安装填料，增加了池内的比表面积，增大了微生物附着载体，经充氧的污水以一定的流速流经填料时，微生物以污水中的有机物作营养源，不断新陈代谢，消耗废水中的有机物，附着于填料上的生物膜不断脱落和更新，保持着接触氧化池的正常连续运行。
Contact oxidation is one of biofilm, which is composed by pool, fill, aeration system. The pool installs fill, so that the surface area increases, which enlarges the attached carrier for microbe. When the oxygenated wastewater flows through the filling with certain rate, the microbe
metabolism constantly, consumes the organic matter. The biofilm on filling keep dropping off and updating to maintain the normal and continuous operation for contact oxidation pool.

It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer.

He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's.

I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia.

He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it!

Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing.

Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing.

'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad.

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong numbers 无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time.

They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket.

This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered.

第三节 沼气产量
Section three Biogas output
高浓度的有机废水在厌氧发酵的过程中产生大量的沼气，理论上废水厌氧过程中每去除1kgCOD可产生0.6 m3标准状况下的沼气，据此计算2200 m3/d，COD浓度为45000mg/l的废水经处理后每天可产生沼气约57000Nm3。
High concentrate organic wastewater will bring out a large amount of biogas in anaerobic fermentation process. In theory, during the anaerobic fermentation process, removing 1kg COD will produce 0.6N m3 biogas. Therefore, wastewater, 2200 m3/d with COD concentration of 45000mg/l, will produce 57000Nm3 per day after treatment.
第五章 沼气发电设计
Chapter Five Biogas generating design
沼气发电系统主要由脱硫塔、沼气柜、发电机组等组成。厌氧产生的沼气经过脱硫塔除去沼气中的H2S，进入沼气柜后经脱水器去除沼气中的液体水，然后进入沼气发电机发电。
The biogas generating system is composed of desulfurization tower, biogas tank, generator, etc. The anaerobic produced biogas is removed the H2S through desulfurization tower, wiped off water by dewatering device in biogas tank, and then enters into the generator.

'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic. Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 如果用于沼气发电机组的发电量为1.6度沼气，则每天的发电量为35625kwh，按0.65元人民币/kwh计，每年（按330天）的收益为764万元人民币。

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in.

该污水处理厂担负着生产污水的净化处理任务,若电源中断,将会造成工业和生活污水的净化处理中断,导致原本由于污水处理厂的建立业已得到改善的生态环境再次遭到破坏,给生产造成较大影响,同时也使污水处理过程中的有用菌大量死亡,即使恢复供电需要达到污水处理排放标准也要有一段较长的细菌培养时间,因此,污水处理站为三班连续生产单位，工程建成投产后，与现有的生产车间属于同一供电负荷等级，生产不停，污水处理站就必须正常运行。
污水处理站供电由就近的生产接入，生产设备用电及照明采用380/220三相四线制供电。

The improved environment will be polluted for the second time and the production will be badly damaged. Large number of useful germ is killed, thus, even the power reverted, it will still need long time to incubate the germ before achieving the water discharge standard. Therefore, the wastewater treatment plan is of 3 shifts production. After the project completed, the power supply burthen is the same with production workshop. The wastewater treatment plant will no stop until the production stop running.
The power supply of wastewater treatment is connected from the nearest access. Production electricity and lighting equipment adopt 380/220 three-phase four-wire power supply.

He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning.

Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681.

The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it!

Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 21

Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town.

Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor.

It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from hifriends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time.

Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good news 佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \Parking\our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day.

Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat. he play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me.

I turned round again. 'I can't hear a word!' I said angrily. ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late.

'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia.

Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds.

'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong number无错号之虞Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer. Lesson 7 Too late 为时太晚 The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand! Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town! Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing. Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's. Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!' Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time.

Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 25

Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions. Lesson 14 Do you speak English?你会讲英语吗？ I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself! Lesson 15 Good new佳音 The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year! Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a \ou will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it! Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!' lesson18 He often does this!他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.' Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said. 'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly. Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all ! Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The 26
