如果我们用一个从句来表达一件事情或一个行为发生的时间, 那么这个从句就叫时间状语从句。

时间状语从句 引导词

when引导的时间状语从句可以用于不同时态,从句动作既可以是延续性动词也可以是短暂性动词。

表示当…时候。从句的动作既可和主句的动作同时发生,又可在主句的动作之前或之后发生。

He fell asleep when he was reading a book in the morning.早上他正在读书的时候，睡着了。

while 表示“当……时候，与此同时”，主从句后通常都可以跟延续性动词。紧跟while的从句既可以放在主句前，也可以放在主句后。放在主句前时，要用逗号分开；放在主句后时，中间无任何符号。

我在看电视的时候我的妻子在刷抖音。

I was doing my homework while he was sleeping. 我正在做作业，与此同时，他正在睡觉。
