復合句的用法
一、狀語從句
狀語從句又可分為時間、地點、目的、原因、結果、行為方式、條件、讓步及比較等幾種形式。
1. I’ll go with you as soon as I ____ my work.
A. will finish B. shall finish C. finish D. finished
答案：C。在時間、條件狀語從句中，主句如果是一般將來時，從句要用一般現在時;如果主句是過去將來時，從句可以用一般過去時。能夠引導時間狀語從句、條件狀語從句的從屬連接詞，常見的有when，until，as long as，if，unless等。如：
(1) Unless he comes, we won’t be able to go.
(2) Lu Xun often said, “As long as I am alive, I shall go on studying.”
2. No sooner _____ the news than they rushed out into the street.
A. they heard B. they had heard C. did they hear D. had they heard
答案：D。no sooner…than，hardly…when表示“—……就”，主句一般用過去完成時，從句用一般過去時，如果hardly，no sooner，scarcely放句首，主謂要倒裝。
3. Although he is considered a great writer, ____.
A. his works are not widely read
B. but his works are not widely read
C. however his works are not widely read
D. still his works are not widely read
答案：A。這是一個讓步狀語從句，主句與從句之間有一個從屬連詞although，不能再加but，however，still等。
4. ____ Mr Smith is well again, he can travel.
A. Now that B. But that C. And that D. Since that
答案：A。now that相當于since。引導原因狀語從句的連接詞常見的有because，as，since，seeing that，considering that等。
5. It was ____ a hundred people looked lost in it.
A. so large a room that
B. so large a room
C. such large a room that
D. a such large room
答案：A。引導結果狀語從句：so+adj.(adv.)+that從句;so+adj.+a(an)+n.+that從句;such+a(an)+ adj.+n.+that從句，表示“這樣……(一個)……以至于……”。
二、定語從句
擔任定語功能的句子稱為定語從句。在做定語從句的練習時，首先應該找出先行詞，然后再確定選擇關系代詞或關系副詞。能夠引導定語從句的關系代詞和關系副詞有who， whom，whose，that，which，when，why，where。
1. She heard a terrible noise, ____ brought her heart into her mouth.
A. it B. which C. this D. that
答案：B。在非限定性定語從句中，關系代詞用which不能用that。
2. He paid the boy for washing ten windows, most of ____ hadn’t cleaned for at least a year.
A. these B. those C. that D. which
答案：D。如果選A、B、C選項，整個句子不符合語法要求，因此只能是一個非限定性定語從句，在非限定性定語從句中關系代詞一般用which。
3. Finally the thief handed in everything ____ he had stolen to the police.
A. after B. what C. whatever D. that
答案：D。A、B、C不能引導定語從句。當先行詞是all，something，everything等時，關系代詞要用that。
4. The man ____ talked to you just now is an engineer.
A. who B. where C. which D. what
答案：A。先行詞是the man指人，關系動詞who指人在定語從句中作主語。
三大類型復合句怎么準確使用
名詞性從句
在整個復合句中起名詞作用，充當主語、賓語、表語和同位語等的各種從句，統稱為名詞性從句。名詞性從句主要有以下幾種：
1. that 引導的從句
e.g. It is reported that one third of Guangzhou citizens planto buy a private car. (據報道，三分之一的廣州市民打算購買私家車。)
2. whether/if 引導的從句
e.g. Whether motorcycles should be banned in Guangzhouhas become an issue of controversy.(廣州是否禁摩托車成了有爭議的話題。)
3. how/why/when/where引導的從句
e.g. This essay aims to explore why so manywhite collar workers suffer from insomnia. (本文將探討為什么這么多白領失眠的原因。)
4. who/whom/whose/what/which引導的從句
e.g. Who should be responsible for theenvironmental degradation is still unknown.(誰對環境惡化負責還不清楚。)
形容詞性從句
具有形容詞功能，在復合句中做定語的從句被稱之為形容詞性從句或定語從句。被修飾的名詞、詞組或代詞被稱為先行詞。形容詞性從句分為兩種類型：
由關系代詞 who, whom, whose, that, which, as引導的從句。
例如：People who arestrongly against human cloning claim that it is immoral and unethical.(強烈反對克隆人的人們認為這樣做不道德和不合倫理)
副詞性復合句
因為壞人帶槍，如果警察不配槍市民就很危險了
As evil people always have guns, it is dangerous for citizens if the police do not carry them.
由于女性的體質不同于男性，她們在軍隊的激烈競爭中比不過男性
