Adverb Clauses of Time

(时间状语从句) 

用来修饰谓语动词、其他动词、定语、状语或整个句子的从句叫状语从句。状语从句有很多种，今天我们主要学习由when, while, before, after, as soon as, since, until引导的时间状语从句。 

when从句的动作可与主句的动作同时发生，也可先于主句的动作；从句的谓语动词可以是延续性动词，也可以是瞬间性动词。并且when有时意为“就在那时”。如：

When I got home, he was watching TV.

当我到家的时候，他正在看电视。

Mozart started writing music when he was four years old.

当莫扎特四岁的时候，开始写音乐作品。

I was about to go out when the telephone rang.

我刚要出门，电话铃响了。 

while只能指一段时间，而不能指时间点。从句的动作或与主句的动作同时发生，或主句的动作是在从句动作的过程中发生的。因此，从句中的动词必须是表示延续性动作或状态的动词。如：

While I was sleeping, my brother came in. 

当我在睡觉的时候，我弟弟进来了。

He visited a lot of places while he was traveling.

他在旅途中参观了许多地方。 

... ... ...

when和while 的区别 

when与while 都意为“当……的时候”。when 引导的时间状语从句, 谓语动词既可以是持续性的, 也可以是终止性的；而while引导的时间状语从句, 谓语动词只能是持续性的, 并且常用进行时态。试比较：

When he woke up, it was eight o’clock．

While he woke up, it was eight o’clock． 

When I was waiting for a bus, I met her．

While I was waiting for a bus, I met her．

before表示主句的动作发生在从句之前。如: 

I won’t tell you the truth before he comes back.  

他回来之前我是不会告诉你事实的。

after表示主句的动作发生在从句的动作之后。如：

After she finished the work, she went to have supper. 

她完成工作后去吃晚饭了。
