Practicing Discovering useful structures
In groups, look at these pairs of sentences(page 37). Discuss the difference between A and B in each pair. Rewrite these sentences taking out the unnecessary parts.
1. The burn that she got from the iron was red and it was very painful.
2. A boy was on the left side of the sick woman, and a girl was on the right side of the sick woman. 3. She has a daughter who is in hospital. 4. He went to the doctor because he had to go to the doctor.

7 When your nose is bleeding, you should bend forward so that the blood runs out of your nose and the blood doesn't run down your throat.

8 Only some of the students have done a first aid course but most of the students haven’t done a first aid course .

复 合 句 中 的 省 略
(1)当状语从句的主语和主句的主语一致时,可以省略状语从句中的主

语和系动词be, 这时从句中可出现如下结构:
①连词(as, as if, once+名词) Once (he was) a teacher, he now works in a government office. ②连词(though, whether, when)+形容词 Work hard when (you are) young ,or you’ll regret. ③连词(when, while, though)+现在分词 While (I was) walking along the street, I heard my name called. ④连词(when, if ,even if, unless, once, until, than, as)+过去分词 ⑤连词(as if, as though)+不定式

He opened his mouth as if (he were ) to speak.

(2)当从句主语是

It,谓语动词有含有系动词be时,可以把 it系动词be一 起省略。此时构成连词( if , unless, when,whenever)+形容 词的结构。如:Unless(it is )necessary,you‘d better not refer to the dictionary.

另外,我们还可以用so或not代替上文内容,此时可有if+so/not。
Get up early tomorrow. If not( you don’t get up early), you will miss the early bus. He may not be at home then, if so (he is not at home), leave him a note.

(3)在than或as…as引导的从句中,常含有一些成分在上下文清楚的情 况下被省略。
He has made greater progress than (he did) before/ever. He came home earlier than (he was) expected. She works as hard as young people.

(4)不定式省略,单独使用不定式符号to
①在 expect,forget,hope,intend,like,love,mean,prefer, refuse,seem,try,want,wish等后面。如:

I asked him to see the film,but he didn’t want to.
②在have,need,ought,be going,used等后面。

③在某些形容词pleased,glad,happy 等后面。
--Will you join the game? --I’d be glad to. ④否定形式的省略用not to。 如果不定式中含有be,have,have been,通常保留be,have,和 have been 。如: --He hasn’t finished yet. --Well,he ought to have.

These sentences are correct. However, one or more words have been left out. Rewrite each sentence including the missing words.

1.The cottage surrounded by a wall belongs to the local government. The cottage (that is ) surrounded by a wall belongs to the local government. 2.The first book I read this term was more interesting than the second. The first book I read this term was more interesting than the second ( book I read this term ).
