【名师点睛】

用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。状语从句可置主语之前，也可置于主语之后。前置时，从句后用逗号与主句隔开；后置时，与主句之间无标点符号。

时间状语从句

(1)时间状语从句常用when/ as/ while, before, after, since, till, until, as soon as等连词来引导。

例如：

It was raining hard when I got to school yesterday.

While he was doing his homework, the telephone rang.

As he walked along the lake, he sang happily.

He had learned a little Chinese before he came to China.

After he finished middle school, he went to work in a factory.

when 、as和 while的区别：

1） when引导的从句的谓语动词可以是延续性的动词，又可以是瞬间动词。并且when有时表示“就在那时”。

例如：

When she came in, I stopped eating.

她进来时，我停止吃饭。(瞬间动词)

When I lived in the countryside, I used to carry some water for him.

当我住在农村时，我常常为他担水。（延续性的动词）

We were about to leave when he came in.我们就要离开，就在那时他进来了。(瞬间动词) 2）While引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。

例如：

While my wife was reading the newspaper, I was watching TV.

(was reading是延续性的动词，was reading和was watching同时发生)

I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。

（对比）

3）As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可

以强调“一先一后。

例如：

We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）

As we was going out, it began to snow.当我们出门时，开始下雪了。

（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）

(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：

I’ll ring you up as soon as I get to New York.

I will tell him everything when he comes back.

He won’t believe it until he sees it with his own eyes.

(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如：

The young man read till the light went out.

Let’s wait until the rain stops.

We won’t start until Bob comes.

Don’t get off until the bus stops.

条件状语从句

(1)条件状语从句通常由if, unless=if …not引导。例如：

(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：

He won’t be late unless he is ill.

(3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如：

=If you don’t hurry up, you’ll be late.

Study hard and you will pass the exam.

=If you study hard, you will pass the exam.
