辨与析
during,when, while 的区别
during后面接名词：I went to visit the Great Wall during the summer vacation.我暑假里去游览了长城。
when,while都意为“当…”，都引导时间状语从句。
when强调时间点，通常译为“当…”，例如：
When she came in, I was cooking. 她进来时，我正在做饭。
while强调时间段，通常译为“正当……”，例如：
While he was cooking, a friend of his came to see him. 当他正在做饭的时候，一个朋友来拜访他。
during比较容易判断或区别：即，后面接名词或名词短语.
when 和 while 用作引导时间壮语，区别在于：
when 引导的时间壮语是比较次要的事件。
如：
When our airplane landed onto the airport, we heard an explosion.
while 引导的时间壮语是和主句平行发生并且几乎同样重要的事件。
如：
While he was writing his book his wife was helping their son for his homework.
