in the tree 与 on the tree.译成中文均为\在树上\但英语中有区别。in the tree表示某人、某事(不属于树本身生长出的别的东西)落在树上,表示树的枝、叶、花、果等长在树上时,要使用on the tree.如:There are some apples on the tree. 那棵树上有些苹果。There is a bird in the tree. 那棵树上有只鸟。 8. some/ any
some和 any既可修饰可数名词,也可修饰不可数名词。但有以下两点需要注意。 (1)some常用于肯定句中,any常用于否定句和疑问句中。如:
There is some water in the glass.Is there any water in the glass?There isn't any water in the glass. (2)在说话者希望得到肯定答复的一般疑问句中,或在表示请求,邀请的疑问句中,我们依然用some。如:Would you like some tea? 9. tall/ high
(1)说人,动物,树木等有生命的东西,主要用tall,不用high,例如 a tall woman 一个高个子妇女a tall horse 一个高大的马
(2)说一个不与地面接触的人和物的高时,要用high,而不用tall,比如人站在桌子上时,飞机飞上天时,例如: He is high up in the tree. 他高高地爬在树上。 The plane is so high in the sky. 飞机在空中这么高。
(3)指建筑物、山时要tall或high都可以,不过high的程度比tall高。 (4)high可作副词,tall不能。
(5)tall的反义词为short, high的反义词为low. 10. can/ could
(1) can表示体力和脑力方面的能力,或根据客观条件能做某种动作的\能力\。例如:

--- Can I use your pen?我能用你的钢笔吗?--- Of course,you can.当然可以。 You can have my seat,I'm going now.我要走了,你坐我的座位吧。 (3) could

表示将来。所有其他时态(包括将来时)须用be able to加动词不定式来表示。 例如:They have not been able to come to Beijing.他们没有能到北京来。 11. look for/ find
look for 意为“寻找”,而find意为“找到,发现”,前者强调“找”这一动作,并不注重“找”的结果,而后者则强调“找”的结果。例如:She can’t find her ruler. 她找不到她的尺子啦。 Tom is looking for his watch,but he can’t find it.汤姆正在寻找他的手表,但没能找到。 12. be sleeping/ be asleep

表示“在街上”时,on the street 和 in the street 都可以,在美国多用on the street, 在英国多用in the street. 例如:We have a house in the street. 我们在街上有座房子。I met him on the street. 我在街上遇见了他。 2. would like / like
would like 和 like含义不同。like 意思是“喜欢”,“爱好”,而 would like 意思是“想要”。试比较: I like beer.=I’m fond of beer. 我喜欢喝啤酒。I’d like a glass of beer= I want a glass of beer. 我想要一杯啤酒。Do you like going to the cinema? 你喜欢看电影吗?Would you like to go to the cinema tonight? 你今晚想去看电影吗? 3. another / the other
(1)another 通常用于三个或三个以上或不确定数量中的任意一个人或 物体。 例如: May I have another apple, please? 请在给我一个苹果好吗?

(2)the other 通常指两者中的另一个。例如:
He has two rulers. One is short. The other is long. 他有两把尺子,一把短的,另一把长的。 I have two brothers. One works in Xi’an . The other works in Beijing. 我有两个兄弟,一个在西安工作,另一个在北京工作。 4. have to /must

(2)have to 可用于多种时态,must 只能用于一般现在时。例如:
I’ll have to get up early tomorrow morning.明天早晨我必须早早起床。We had to work long hours every day in order to get more money.为了多挣钱,我们不得不每天长时间地工作。 (3)用于否定句时,mustn’t意思是“决不能”,“禁止”,而don’t have to意思是“不必”,相当于needn’t。例如:You mustn’t be late again next time.下一次你决不能再迟到。You don’t have to go there today. You can go there tomorrow.你今天不必到那里去了。你可以明天去。 5. hear sb. or sth.doing sth. / herar sb. or sth. do sth. hear sb. or sth.doing sth.意思是“听到某人或某物在做某事”,而hear sb. or sth. do sth.意思“听到某人或某物做过某事”。试比较:I hear him singing an English song.听见他在唱英歌曲。 I heard him sing an English song.我听见他唱一首英文歌。
类似hear 这种用法的还有see, watch, listen, feel等感官动词。 6. any /some
any和some 都可以同不可数名词和可数名词的复数形式连用,但some一般用在肯定句中;any用在疑问句和否定句中。试比较:I want some money. 我想要点钱。Have you any money? 你有钱吗?I don’t have any money. 我一点钱也没有。
some 有时也用于疑问句,表示说话人期待一个肯定回答或鼓励人家说“是”。例如: Would you like some more beer?请你再来点啤酒好吗? Could I have some rice, please?请给我来点米饭好吗? 7. hear /listen to
listen to 和hear 都有“听”的意思,但含义有所不同。Listen to强调“听”的动作,hear 强调“听”的结果。例如:Listen to me ,please! I’m going to tell you a story. 请听我说!我给你们讲个故事。
Listen! Can you hear someone crying in the next room? 听!你能听见有人在隔壁房间里哭吗? I listened, but heard nothing.我听了听,但什么也听不见。 hear 后面如果接宾语从句,常常表示“听说”。例如:
I hear some foreign students will visit our school.我听说一些外国学生将要访问我们学校。
I hear there is going to be a film in our school this evening.我听说今晚我们学校要演一场电影。 8. Let’s… /Let us…
Let’s… 和Let us… 都表示“让我们……”, 如果us 包括听话人在内,其含义相同,附带问句用shall we. 如果us 不包括听话人在内,其含义不同,Let us…的附带问句要用will you。例如:Let’s go shopping, shall we? 我们去购物好吗? 9. take/ bring/ carry /get
