状语从句用法详解
在主从复合句中修饰主句的动词、形容词、副词等的从句叫状语从句。
一 时间状语从句:起时间状语作用的从句。when, while, as, after, before, until/till, since, as soon as, immediately, the moment, every time, whenever等。
1. when, while, as
1) when“当......的时候”,表示主从句的谓语动作同时发生或先后紧接着发生。
I was very happy when I heard from you.
When you deal with them, you should be cautious.
When I was young, I went to town myself. (延续性动词)
When the fire broke out, all the students were sleeping soundly.(非延续性动词)
As a young man(=When he was a young man), he was fond of hunting.
2)while引导的时间状语从句中谓语动词必须是延续性动词或表示状态的动词,侧重主句动作和从句动作相对比。
My father was preparing a report while I was playing games.
Please don't talk so loud while others are working.
3) while 意为“虽然,尽管”,还能引导让步状语从句.
While it was late, he went on working. (虽然很晚了,但他还在继续工作.)
While he is in poor health, he works hard. (虽然他身体不好,但他还是努力工作.)
4)连接两个并列句子,表示“对比”关系.例如:
He went out for a walk, while I stayed at home. 他出去散步了,而我却呆在家里.)
