when,as,while这三个词都可以引导时间状语从句,它们的差别是:
1.when 从句表示某时刻或一段时间,即在某个时间点上.谓语动词既可以表示延续性行为状态,也可以表示瞬间动作,后者更常见,如:
* When he left the house,I was sitting in the garden.当他离开家时,我正在院子里坐着.(left 是瞬间动作)
* When he arrived home,it was just nine o'clock.当他到家时,正是九点钟.(arrived 是瞬间动作))
* When I was young,I was sick all the time.在我小时候我总是生病.(was young 是延续性状态)
2.as 从句表示进展过程,意思是“随着某个行为向前进展的时候”或“在某个行为进展过程中”,如:
* As he grew older,he became more intelligent.随着他年龄的增长,他变得更有才智了.
* I slipped on the ice as I ran home.我跑回家时在冰上滑了一跤
2.while 只表示在一段时间内的延续行为状态,即“就在某个行为进行的中间”,如:
* While he was in London,he studied music.当他在伦敦时,他学习音乐.
* While she was typing the letter,the telephone rang.当她在用打字机打那封信时,电话响了.
