对while\when引导的时间状语从句都可以用When进行提问?~
我的意思是对该时间进行提问:例如:
He was sleeping while you were doing your homework.
提问是:When was he sleeping?~

可以
when有2个意思 一个是“什么时候”，是疑问副词，对时间提问。另一个是“当什么时候”一道时间状语从句。 所以对时间状语提问时可以用when.
when 和while的区别：
一。引导时间状语从句时，while连接的是时间段，而when连接的多是时间点
例如What does your father do while your mother is cooking?
What does your mother do when you come back?
二，while可以连接两个并列的句子，而when不可以
例如I was trying my best to finish my work while my sister was whtching TV
三，when 是特殊疑问词，对时间进行提问，while不是。
例如，When were you bron?
