句式精讲
1. It’s too far to cycle.
too…to…意为“太……而不能”。它在结构形式上是肯定的，但意义上却表示否定含义，所以动词不定式符号to前不能再加not，只接动词原形即可，too后接形容词或副词原形。例如： The book is too difficult to understand. 这本书难于理解。 【拓展】
（1）在too…to…句型中，当动词不定式的动词是不及物动词，其后所跟的介词不能省略。例如： The room is too small to live in. 这房间太小了不能住。
（2）在too…to…句型中，当动词不定式的宾语实际上就是这个句子的主语时，动词不定式后面不能
再加代词作宾语。例如：
The question is too difficult to answer. 这个问题太难了，无法回答。
（3）在too…to…句型中，当动词不定式能确切说明动作执行者时，可以在动词不定式前面加上逻辑
主语，即for sb.形式。例如：
The box is too heavy for him to carry. 箱子太沉了，他搬不动。
（4）含too…to…的句子可以改写成so…that…句型，意为“如此……以至于……”。例如： He is too old to do hard work. =He is so old that he can’t do hard work.
他年纪太大而不能干重活。
（5）含too…to…的句子也可以用“not + 形容词/副词 + enough to do sth.”句型来替换，但注意
要用原句中形容词或副词的反义词。例如：
He is too old to do hard work. =He is not young enough to do hard work.
他年纪大了，不能做重活。
2. I have some exciting news to tell you.
to tell you由to+动词原形构成的动词不定式，在句子中作定语，放在所修饰的名词之后。例如： Do you know the best way to learn English well? 你知道学好英语的最佳方法吗？ 【注意】
动词不定式作定语时，总是后置，不定式与其所修饰的词构成逻辑上的动宾关系，而该不定式为不及物动词时，其后须加上适当的介词，构成及物动词短语。 例如： I am looking for a room to live in. 我正在找一间屋子住。 I need a piece of paper to write on. 我需要一张写字用的纸。 【拓展】
不定式还有以下用法： （1）作主语。例如：
To see is to believe. 眼见为实。
（2）作宾语。这样的动词有：want; hope; ask; decide等。例如： I want to be a football player. 我想成为一名足球运动员。
（3）作宾语补足语。这样的动词有：ask; teach; want; tell; allow等。例如： He asked me to come here in time. 他叫我及时到达这里。 （4）作表语。例如：
My wish is to become a famous pianist. 我的愿望就是成为一名著名的钢琴家。

3. Why don’t we go out for the day?
“Why don’t +主语（名词或代词）+动词原形+其他？”相当于“Why not+动词原形+其他？”并不表示疑问，而是征求意见和提出建议。例如：
Why don’t you go swimming? = Why not go swimming? 为什么不去游泳呢？ — Why not play football with us? 为什么不和我们去踢足球呢？ — That sounds like a good idea. 这是个好主意。 4. While Jane was singing, I was reading a book.
while 作连词，意为“当……时候”，引导时间状语从句，并且是主句和从句动作同时发生，从句中的动词必须是延续性动词或表状态，且常用进行时态。例如：
He came in while I was watching TV. 当我在看电视时，他进来了。 【拓展】
while; when与as的辨析：
（1）while强调动作同时进行，从句常用进行时，其动词必须为延续性动词或表状态。例如： He was watching TV while she was cooking. 她做饭时，他在看电视。
（2）when既可指动作同时进行，也可指先后发生，从句中的动作既可是延续性动词，也可是非延续性动词。若是同时发生且为延续性动词，则可与while互换；若when作并列连词，表示“就在那时，这时候”则只能用when，并且when引导的从句只能放在后面。例如：
When the alien got out, the girl was shopping. = While the girl was shopping, the alien got out.
当外星人出来时，小女孩在购物。
We were watching TV when there was a knock at the door. 我们在看电视，这时有人敲门。
（3）as多指主句从句两动作同时发生，常翻译为“一边……一边……”。例如： They talked as they walked. 他们边走边谈。 5. Bicycle riding is good exercise. bicycle riding为动名词短语，在句子中做主语。动名词作主语时，谓语动词要用第三人称单数形式。例如：
Swimming is good for our health. 游泳对我们的健康有益。 【拓展】
动名词和不定式都可以作主语，但在用法上有区别：
（1）不定式作主语通常表示一次性、未来的且具体的特指动作，而动名词作主语通常表示习惯性、经常性和不具体的泛指动作。例如：
Walking is a good form of exercise for both the young and the old. 步行对年轻人和老年人来说都是一种好的锻炼形式。 To carry the heavy box is not easy for the boy. 对这个男孩来说，搬这个箱子是不容易的。
（2）动名词作主语和不定式作主语有时可以互换。例如：
Playing with fire is dangerous. = To play with fire is dangerous. 玩火是危险的。 6. If people obey the traffic rules, there will be fewer accidents.
if做连词，意为“如果”。本句是含有if引导的条件状语从句的复合句，要注意：if 条件状语从句
中，主句用一般将来时，从句用一般现在时表示将来。遵循“主将从现”原则。另外，主句也可以用祈使句或含有情态动词的句子。例如：
We will go to the park if it doesn’t rain tomorrow.
2
如果明天不下雨，我们就去公园。 Don’t wait for me if I am late. 如果我晚了就不要等我。
If you want to lose weight, you must eat less bread. 如果你想减肥，你必须少吃面包。 7. We should never ride too fast.
should作情态动词，意为“应当，应该”。表示义务、责任，可用于各种人称，无人称和数的变化，也不能单独作谓语，只能和动词一起构成谓语，表示说话人的语气和情态；否定形式为should not，缩写为shouldn’t。其主要用法有：
（1）表示责任和义务，意为“应该”。例如： You should take your teacher’s advice. 你应该听从你老师的建议。
You shouldn’t be late for class. 你不应该上课迟到。
（2）表示推断，意为“可能，该”。例如： The train should have already left. 火车可能已经离开了。
