状语从句表示短时间的动作，主句常用进行时态或完成时态。
When I came in, he was reading the newspaper.
从句用过去时，谓语是非延续性动词（come, go, leave, arrive, meet, die）
主句用过去进行时，谓语是延续性动词
易错点1
while的用法
when和while引导时间状语从句
从句用过去进行时，主句用一般过去时。
While I was watching TV, Tom came in.
主句用过去时，谓语是非延续性动词（come, go, leave, arrive, meet, die）
从句用过去进行时，谓语是延续性动词
when和while都可表示“当……的时候”，引导时间状语从句。你理解了两者在过去进行时中的用法有什么不同吗？
