细微的差别，词的感觉，这里的说是你我他都说，时间不固定，昨天说今天说明天还会有人说，when强调某一时刻，比如瞬间动词就不能用while只能用when,这里是另一头，只能用while,when 不合适

我进门的时候看见你吃饭，就只能用when。因为进门是瞬间动作，话没玩动作就完了。while这个当。。。时。。是用在持续一段时间的动作上，不持续不能用

你吃饭的时候看见我进门，两个就可以都用

举报 xa2004

这题中就是能用while 不能用when的情况，就好像你管屋里我管屋外在门的地方咱俩都可以管，靠里屋我就管不到了而大门外你就管不到了。

这两个词的差别老师没有给你们讲吗？

没有，请你概一下，谢谢。

概括一下，谢谢

都给你讲了，WHEN多指一个时间点，WHILE多指时间段
