复合句—状语从句

一、复习目标：

（1）掌握状语从句的作用。

2）掌握状语从句的意义。

（3）掌握各种不同类型的状语从句。

二、知识要点：

状语从句在句中作状语，修饰句中的动词、形容词或副词等。状语从句由从属连词作关联词，从属连词在从句中不充当句子成分。状语从句在主句之前，一般要用逗号分开，朗读时用升调。状语从句在主句之后，一般不用逗号，朗读时用降调。

状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等类型。

1. 时间状语从句

(1) 常用的连词有when（当……时候），while（当……时候）,before(在……以前)，after（在……以后），until(till)（直到……为止）,since（自从……以来）,

as soon as（一……就）等。

(2) 时间状语从句中一般不用将来时，若谈论将来的事情，往往用一般现在时代替：

如：I'll go on with the work when I ________ (come) back tomorrow.

As soon as he ___________(finish) the work, he will come to see me..

2. 条件状语从句

常由if (假如、如果) No matter (不管) 来引导，如果主句是一般将来时，从句往往用一般现在时来表示将来。

如：I'll go for a picnic if it _____(be) fine.

No matter what he ________(say)，I won't believe him，

3. 原因状语从句

(1) 常由because, since, as引导。

(2) because表示直接的原因，着重点在从句，用于回答why, 语气最强。because 不能与so 连用。

since一般表示对方已知的，无须加以说明的既成事实的理由，全句中心在主句，语气比because弱，常译为“既然”。

as表示十分明显的原因，一般说明因果关系，着重点在主句，语气较弱。常译为“由于”。

for是个并列连词，只能放在另一个并列分句后面，表示一种推理或解释，或用作附加说明，而不是指理由或原因，语气最弱，一般不放在句首，常译成“因为”。

如：______ it is raining hard, we won't go hiking.

_______ you are ill, I'll go alone.

I can't go to school ________ I am ill.

You haven't met him, ______ he didn't come here.

4. 结果状语从句

一般由so...that, such...that引导，so 与such的区别：(1) so＋形容词＋a / an＋名词

(2) such＋a / an＋形容词＋名词（3）such＋形容词＋不可数名词/ 可数名词复数

(4) so＋many / much / few / little＋形容词＋名词

如：It's _______ a heavy box that nobody can move it.

It's ______ heavy a box that nobody can move it.

There are _________many books in the library

5. 目的状语从句

往往由so that,引导，如：I'll speak slowly_________ you can understand me.

6. 比较状语从句

常由as...as, than, not as / so...as等引导。比较从句部分常是省略句，

如：I'm taller ______ he (is).

Science is not _____ popular _____ English.

7. 让步状语从句

由though或although (虽然) 等引导，但不能与but同时连用，

改错：Though it snowed heavily,but they kept on working.

8 方式状语从句

常用as if ,as though（好像）引导。如：He acted as if (though) nothing had happened.

9、地点状语从句

常用where, wherever引导。

如：I'll go where work is hard.

典型例题解析

例1 The question was _______ difficult that nobody could answer______.

A. very...them

B. very...it

C. so...them

D. so...it

解析因为句中有that,所以前面用so,构成so……that从句，而question是单数，用代词it，故选D。

例2 It was ______that he had to ask for help.

A. such big work

B. so big a work

C. so a big work

D. such big job

解析work是不可数名词，指工作或工程，故选A。

例3 He won't believe it ________ he sees it with his own eyes.

A. when

B. after

C. until

D. as soon as

解析此句是not……until,“直到……才”。故答案选C。

例4 I'll go _____ with you _______ next Sunday.

A. hunting...when I will have time

B. to hunt...until I'm free

C. boating...if I have nothing to do

D. to boat...as I will not be so busy

解析去打猎、划船常用go hunting, go

boating，所以应在A和C中选择，又因为when和if在句中引导状语从句时，要用一般现在时表示将来，故选C。

例5 It's almost three years _________ I last saw her.

A. since

B. when

C. that

D. after

解析本句表示自从上次见到她几乎有三年了，句型It's+时间段+since从句(过去时)，故选A。

三、选讲例题

用所给动词适当形式填空

例6 I'll go to Shanghai if I _______ (have) time tomorrow.

And I want to know if you ________ (have) time to go with me.

解析第一句中if是“假如”的意思引导状语从句，要用一般现在时表示将来时，第二句中if是“是否”的意思，引导宾语从句，仍用将来时。

例7 —Could you tell me when he ________ (return) home next week?

—Sorry, I can't. But I will ring you up when he _________ (return) home.

解析

第一句中的when意思是“什么时候”，引导宾语从句用将来时态，第二句中的when是“当……时”的意思，引导时间状语从句，用一般现在时表示将来。
