释疑依据:(与过去有关)在时间状语从句的复合句中延续性动词,

释疑1:
什么时候用when?什么时候while?

如:It was raining hard when we arrived. 我们到达时正下着大雨。
2、“主长从长”型:即主句和从句为两个同时进行的动作或存在的状态,且强调主句动作或状态延续到从句所指的整个时间,此时通常要用while。
Mum was cooking while Tom was watching TV. 当汤姆正在看电视的时候,妈妈正在做饭。
3、“主短从长”型:即主句是一个短暂性动作,而从句是一个
持续性动作,此时用when/while。。
如: Jim hurt his arm while/when he was playing tennis.
吉姆打网球时把手臂扭伤了。
