定语从句的关联词基本与三种名词性从句的关联词相同,what只能引导名词性从句,即(主语从句、表语从句和宾语从句)合称为名词性从句。如;What made him come is a question.Do you know what he is doing?定语从句需位于被修饰的名或代词之后,如;I know the man who is standing there.宾语从句则直接承受主句的谓语行为,如,I know who is standing there.注意,这也是为什么主格who经常可以换用宾格whom的原因,但介词之后的whom不可换用who,因为介词有及物的动态理念!when,where本身只是疑问时间和地点的副词用作从句关联词,因此只能在从句中用作与其本身作用相应的从句成分,如;Do you know where he is from?do you know when he came?When he came,I had finished my work.本回答被提问者和网友采纳

we changge the way we speak when talking with differet people
这个句子里的when引导的是时间状语从句 省略了we are , 也就是说 整个句子应该是 we changge the way we speak when (we are )talking with differet people
由于状语从句的逻辑主语和句子的主语相同, 所以可以省略状语从句的主语和be动词
