时间状语从句中when和while的区别
when常引导一般过去时的句子，而while引导的前后两个句子常用过去进行时。
when和while在句子中可以转换，但while从句中要用延续性动词，而when从句中既可以用延续性动词，也可以用非延续性动词。
如：I was watching TV when my mother came back.=While I was watching TV,my mother came back.
Find the rules.
延续性动词，也叫作持续性动词，表示能够延续的动作，这种动作发生后可以一直持续下去。
非延续性动词，也叫作终止性动词、瞬间性或短暂性动词，表示不能延续的动作，即动作从发生到结束所持续的时间非常短，且大多都是动作发生后也就马上结束。
learn, work, stand, study, know, walk, keep, have, sing, read等
open, die, finish, begin, come, leave, move, go ,buy等
