5、 your bag, or it will be lost. =Your bag will be lost if you arent careful with your bag.2.

7、. I didnt speak of it until yesterday.4. I didnt fall asleep until it was one oclock.5. They didnt start the dinner until Jack came.（六）crowd 的用法作为动词，crowd 表示“聚集”，例如： 1.

8、例如：3. The road is crowded with cars and buses.4. The room was crowded with people.（七）asas one can（= asas possible）意思是“尽可能地”，把形容词或副词放在第一个 as 后面，两种表达形式都可以。例如：1.

9、s possible）.3. You must be as careful as possible/as you can when you do your homework.4. We have to finish the work as soon as we can/as possible.5.

10、r woman walked along the street with a baby on her back.3.

11、 old friend of his. （2）She bought a newspaper on her way to the post office.但是，on ones way 与 home，there，here 等词连用时，不要加 to。例如：（3）Dont worry.

12、d about your lessons. You have to get strong first.（十）Soon the lady came to e to oneself 恢复正常1. She came to herself after she was brought to a hospital.2. Give her some coffee with sugar in it and she will soon come to herself.（十一）It is +形容词+（for sb.）to do 与 Its +形容词+of sb + to do sth.It 是形式主语，（for
13、sb.）+ to do 是逻辑主语和真正的主语，如要强调不定式动作的执行者，就在不定式前面加 for sb.，形容词表示的是整个不定式的情况是如何或怎样。如：1. Its important for him to study well at school.2. It will be all right for him to go to school.3. Its not difficult for one to do a bit of good.4. It was easy for me to answer the question.5. It will be a mistake for us
14、 not to help them.在以某些形容词作表语时，不定式前的 for sb.常改为 of sb.，这些形容词往往强调人的情况，常见的有：kind, nice, good, clever, foolish, wrong, polite, careless 等。例如：6. Its kind of you to think so much of us.（=You are kind to think so much of us.）7. Its very clever of him not to take the gift.8. Its very nice of you to come and
15、 see me.9. Its polite of him to say so. 10. It was careless of him to make so many mistakes.注：注：of sb.之前的形容词往往是人性的，即说明人的品质的好坏及自身的特点，如聪明愚蠢，细心粗心等。for sb.之前的形容词往往是物性的，说明事物本身的特点，如可能性、必然性、难易。本单元的重要语法是过去进行时态，when 和 while 引导的时间状语从句与这一时态连用。所以区别 when 和 while 的用法成了这一单元的难点。（一）when，while 都有“当时候”的意思。when 既可表示某一点
16、时间，也可以表示某一段时间 。在 when 引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，可与主句中的谓语动词同时发生，也可在其后发生。1. I was just reading a book when she came into my room.2. Were you writing when the teacher came in?3. When he was a child he was always trying out new ideas.（二）while 只能表示某一段时间，不能表示某一点时间。在 while 引导的时间状语从句中，其谓语动词只能是延续性的，而
17、且也只能与主句中的谓语动词同时发生或存在。1. While Jim was mending his bike, Lin Tao came to see him.2. You cant do your homework while youre watching TV.（三）另外，when 和 while 的区别还在于：while 引导的时间状语从句多用进行时态，而 when 引导的时间状语从句多用一般时态。例如：1. While they were talking , the bell rang. 2. I was doing my homework when my mother came ba
18、ck home yesterday evening.3. A woman saw it happen when she was walking past.这是一般过去时和过去进行时比较典型的搭配，表示一个动作在发生的过程中，又有另一个动作发生，when 引导的是一个时间状语从句。（1）Jane hurt her leg when she was swimming . She didnt notice the big rock in the river.（2）Tom dropped his camera when he was passing the bridge.4. While we wer
19、e talking， the teacher came in.这是个复合句。其中 while we were talking 是由 while 引导的时间状语从句。这里 while 表示主句的动作是发生在从句所表示的时间之中。显然，while 所表示的是一段时间，不是表示一点时间。试比较：（1）They were sweeping the floor when the teacher came in.（2）While they were sweeping the floor, the teacher came in.【典型例题典型例题】1. I often hear him _English.
20、A. to sing B. sings C. sing D. singing答案：答案： C解析：解析： hear 与 see、 watch、 feel 等词一样，是感官动词，其宾语后面做补语的动词不定式不带 to，表示曾经或经常听见某人干某事。2. _ very kind_ you to help me.A. That .of B. Thats .for C. Its . of D. Its .for答案：答案：C解析：解析：“Its+形容词+of sb. +to do sth.”意为“某人做真是太了” ，表说话人对某人的感谢，赞扬或不满的情绪。本句的意思为“你帮助我真是太好了” 。3. S
21、he came into the classroom_ a small box_ her hand.A. with. on B. have. in C. with. in D. having. on答案：答案：C分析：分析：“with+名词+介词短词”这一结构在句中做状语，表示伴随情况。介词的使用需视其后面的名词而定，under ones arm, on ones back, in ones hand.4. The boy ran towards school_.A. as fast as he could B. as fast as he canC. so fast as he could
22、D. so fast as possible答案：答案：A分析：分析：“as+形容词/副词+as one can”意为“尽可能地” ，也可以用“as+形容词/副词+as possible.”第一个 as 为副词，第二个 as 为连词，can 的时态要与主句动词相一致。5. The teacher tells us_ football in the street.A. play B. not play C. not to play D. dont play答案：答案：C分析：分析：tell sb. to do sth.中的不定式符号 to 不可省去，因此 A 和 B 都不对，不定式否定结构，应在
23、 to 前加 not，而不可加 dont，所以 D 不对。【模拟试题模拟试题】（答题时间：40 分钟）一. 选择题。1. _ trees have been planted in our school in the past 10 years.A. Thousands of B. Two thousandsC. Thousand of D. Two thousand of2.
