when和while的区别
1.在连接时间状语时，请先看几个例句1)when I came in.she was cooking,(while不可替代when）
2） When I was cooking,she was reading(while 可替代when).也就是说。when 引导的从句谓语动词即可是终止性动词也可是延续性动词。而while 引导的从句谓语动词是延续性动词
2。when可连接宾语从句而while 不可We don't know when we can go out.
3. while可以表示转折 而when 不可She is tall,while her sister is short
