英语中的九大状语从句

状语从句在主从复合句中修饰主句中的动词、形容词或副词等，按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。

一．时间状语从句。

通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。例如：

The cyclist started just as the lights changed to green.

Whenever we met with difficulties , they cam to help us.

He didn’t leave his office until he had finished the day’s work.

应注意的问题

1．在时间状语从句中，通常要用动词的一般现在时态表示一般将来时态，用一般过去时态表示过去将来时态。但when 引导一般疑问句或名词性从句时不受上述语法规则的限制，因此，应该加以区分。例如：

When China will enter WTO depends on the bilateral (双边的)joint efforts.

Once you understand the rules of the game, you’ll enjoy it.

, while, as 的不同用法。一般说来，当主、从句的动作是同时发生的事，三者可以换用。when 既可以引导一个持续动作，也可以引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作；while 引导的动作必须是持续性的，强调主句和从句的动作同时发生，往往侧重主句和从句动作的对比；as 用于引导“在某行为的继续中发生某事”的“继续之行为”，所以多与过去进行时连用，翻译成“一边……一边……”或者表示动作的变化，翻译成“随着……”。

例如：

I hope you’ll think of my words as/when/while you drive on the busy roads.

When he realized it, the chance had been lost.

When he came home, I was cooking dinner.

I was fat when I was a child.

He took a bath while I was preparing dinner.

As I was walking down the street, an American asked me for the directions to the nearest station.

He sang songs as he was taking a bath.

As he gets older he gets more optimistic.

另外还必须注意 when和while 的特殊用法。when 可以表示“就在这时，突然”之意；而while 则可以表示对比的含义，常可译作“而”。例如：

She thought I was talking about her daughter, __, in fact, I was talking about my daughter.(NMET95)

A. whom

B. where

C. which

D. while

答案：D. 本句的意思是“她认为我在谈论她女儿，然而，实际上，我在谈论我女儿。”

再如：

I was about to go to bed when the phone rang a second time.

我正准备去睡觉，就在这时电话铃又响了。

3．since 和before 的用法区别。两者都可用于“It + be + since/ before-从句”的句型，区别在于 since 表示“自从……以来”，所在主、从句的谓语动词的时态关系是：It is/has been some time since sb did something. 而before 的含义则是“（过了多久）才……”,主、从句的时态关系是：It was/ had been some time before sb did sth。表示过去和将来时，两者相应的句型分别是：It was some time since sb had done something. 和It will be some time before sb does something. 例如：

It was / had been years before I came back from abroad.

It will be five years before we meet again.

4.一些表示时间的名词词组如： the first time, the second time, last time，the moment, the minute，the year, every time, each time , next time, 或副词immediately, instantly, directly等也可以引导时间状语从句。例如：

I’ll tell you about it the moment you come.

I recognized her the minute I saw her.

I’m going to see him next time he comes to Shanghai.

He left Europe the year World War II broke out.

I got in touch with him immediately I received his letter.

My sister came directly( = as soon as ) she got my message.

和until

till 和until 意义相同，多数情况下可以换用，但用以强调，句首多用until; 在强调结构或与not 连用时多用until. 例如：

Nothing can be done till/until the boss returns.

We waited till/until they came back.
