while 可用when代替,等于 “at the time that”, “during the time that”。
while, when, as 时间状语从句 When I went into the lab, the teacher was doing an experiment. He often makes mistakes when he is speaking English. when引出的时间状语从句中的谓语 动词可以是终止性的,也可以延续 性的。因此主句和从句的谓语可以 是一般时,进行时,或完成时。
如果原因构成句子的最主要部分,一 般用because ,因此because引导的 从句往往放在句末。用why提问的句 子,一定用because回答。
because, since, as
