1. 用when引导:when表示“当……时候”。如:
Things were different when I was a child. 我小时候情况与现在不同。
People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。
2. 用while引导:while表示“当……时候”。如:
We must strike while the iron is hot. 我们要趁热打铁。
I went swimming while the others played tennis. 我去游泳,其余的人都打网球去了。
注意:while 所引导的时间状语从句中谓语动词必须是持续性的,不能是短暂性的。
3. 用as引导:as表示“当……时候”“随着”。如:
He dropped the glass as he stood up. 他站起来时,把杯子摔了。
We get wiser as we get old. 随着年岁的增长,我们也变得聪明些了。
4. 用before引导:before表示“在……之前”。如:

Before he went to university he was a worker. 上大学之前他是工人。
5. 用after引导:after表示“在……之后”。如:

6. 用until / till引导:until / till表示“直到……”。如:
He waited until she was about to leave. 他等着一直到她准备离开。
I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。
这类句型的主句动词通常只能是延续性动词,不能是终止性动词。但是,在否定句中,主句动词可以是终止性动词,此时构成not…ntil [till]…句式,意为“直到……才……”。如:
She didn’t marry until she was over fifty. 她直到五十多岁才结婚。
We’d better not go until your sister arrives. 我们等你姐姐到了再走。
7. 用since引导:since表示“自从……以来”。如:
We have known each other since we were children. 我们从小认识。
They’ve moved twice since they got married. 他们结婚后已搬了两次家。
这类句子的主句通常用现在完成时。但是,当主句表示一段时间时,可用一般现在时代替现在完成时。如:
It’s a long time since we met last. 好久没见面了。
How long is it since you came in London? 你来伦敦有多久了?
