考点直击：

1. 时间状语从句

2. 条件状语从句

3. 让步状语从句

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。

1. 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 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.

(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.

2. 条件状语从句

(1)条件状语从句通常由if, unless,as long as（除非；只要），supposing（假设），

on condition that（条件是），in case（如果）引导。例如：

What shall we do if it snows tomorrow?

Don’t leave the building unless I tell you to.

(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：

I’ll help you with your English if am free tomorrow.

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：

Hurry up, or you’ll be late.

=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.

3. 让步状语从句

(1)让步状语从句通常由although, though等连词引导。例如：

Though he is young, he knows a lot.

Although I am tired, I must go on working.

(2)although(though)不能用在同一个句子中。例如：

我们不能说：Though it was raining hard, but he still went out.

应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out. 【经典例题】

1. (2004年北京市海淀区中考试题)

A. if

B. how

C. before
