我不清楚When 和While的细致区别，请老师能够解答的详细点！！ Thank you
解题思路： 见下
解题过程：
While:
1、表示“而”，强调前后2种情况的对比。前后句子的时态、短语、词形往往相同，呈对称的状态。此处不能用when。
I like music while my brother love sports. 我喜欢音乐而哥哥喜欢运动。
My mother was cooking while my father was reading。 妈妈在做饭而爸爸在读书。
2、时间状语从句连词。从句的动词必须用延续性动词。“在……期间内”.
While I lived in the countryside, I made a lot of friends.
She fell asleep while she was reading.
When
1. 时间状语从句连词。从句的动词没有限制，延续性和短暂性的动词都可以。因此，when大于while的用法，以上的2个例句都可以把while换成when。即：
When I lived in the countryside, I made a lot of friends.
She fell asleep when she was reading.
而：When she came in, I was doing my lessons. 此句中的when后面用的came是短暂性动词，是不能换成while来引导的。
2. 用于特殊句型：
be doing＋when＋did “正在做……这时……”
We were doing homework at home when the light went out. 我们正在做作业，这是灯灭了。
be about to do ＋when ＋did“正要做……这时……”
They were about to go out when it began to rain. 正要出门这时下起雨来了。
以上2个例句中的when是不能用while代替的。
