when, while, as 三者都可引导时间状语从句,表示“当……的时候”。如果主句表示的是短暂性动作,而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时,三者可以互换。
when
I'll go home when I have finished my job.
我完成了工作再回家。(动作先后发生)
It was raining hard when we arrived.
当我们到达的时候,雨下的很大。(动作同时发生)

when既可指较短的时间(或某一具体时间),也可指一段时间。主句和从句的动作可以同时发生,也可以先后发生。若从句是一个短暂性动作,主句是一个持续性动作,就要用when。

while 表示“在……期间”,常表示一段较长的时间或一个过程,强调主句的过程与从句的动词所表示的动作和状态是同时发生的。从句中常用延续性动词。
Please don't talk so loud while others are working.
在别人工作的时候,请不要这么大声说话。
while
as
I caught him just as he was leaving the building.
他正要离开大楼的时候,我把他拽住了。
As time goes by, my memory seems to get worse.
随着时间的流逝,我的记忆力变得似乎越来越差。
as与以上两者同义, 常可与when或while 通用,但它着重指主句与从句中动作同时发生,不是一前一后。因此,常作“一面……一面……”解,as 还可翻译成随着。
