1.定义：
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。
2.引导词：
时间状语从句
when/while/as;
before/after;
until; till
since;
as soon as...
each time/every time/whenever
when / while / as 当...时候

I feel very happy when you come to see me.
①when 意为“当……时”，引导的时间状语从句表示主句的动作和从句的动作同时或先后发生。
②when 引导的时间状语从句中，可以用延续性动词，也可以用短暂性动词。

While he was making a phone call,I was writing.
① while 意为“当……”时引导的时间状语从句表示主从句的动作在同一时期发生，常用延续性动词。
注意：while 也可以作并列连词，表转折的关系，相当于but，译为“然而”
as: 一边....一边......
As I was doing my homework,
I was playing on the phone.
As they walked, they talked happily.
由when/while/as引导的时间状语从句区别
