when, while的区别:when引导的从句的谓语动词可以是延续性或瞬间动词。并且when有时表示“就在那时”。例如:
When she came in, I stopped eating.她进来时,我在吃饭。(瞬间动词)
When I lived in the countryside, I used to carry some water for him.当的住在农村时,我常常为他担水。(延续性动词)
We were about to leave when he came in.我们就要离开,就在那时他进来了。
when也可表示条件,相当于 if ,引导条件状语从句。 如: How can I get a job when I can't even read or write? 如果我连读和写都不会,我怎么能找到工作呢?
While引导的从句的谓语动作必须是延续性动词,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如:
While my wife was reading the newspaper, I was watching TV. (was reading和was watching同时发生)
I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。(对比)
