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：
