when和while都可表示“当……的时候”，引导时间状语从句。你知道两者在过去进行时中的用法有什么不同吗？

?? 3. 以when和while引导的时间状语从句
1) 延续性动词和非延续性动词
????延续性动词指动作可以延续一段时间, 而不是
瞬间结束。
????如: work、study、drink、eat等。
????非延续性动词指动作极为短暂，瞬间结束。
????如: start、begin、hit、jump、knock等。
2) 在本单元中, 出现了以when和while引导的
时间状语从句。
when表示“当……的时候”。从句中既可用延续性
动词, 又可用非延续性动词, 这些动词既可以
表示动作, 又可表示状态。从句中的动作既可
和主句的动作同时发生, 又可在主句的动作之前
或之后发生。如：
????Mary was having dinner when I saw her .
????The boy was still sleeping when his mother got
home yesterday morning .
① I was walking to school when I saw a cat in a tree.
②When Sally arrived home, her mother was cleaning the house.
主句的动作是持续性的，而从句动作是
短暂性的，此时用 ______ 引导时间状语从
句，主句用 __________ 时态，从句用一般
过去时态。
过去进行
when
③ While I was sleeping in the bedroom, someone knocked at the door.
④ David fell while he was riding his bike.
主句的动作是短暂性的，从句的动作
是持续性的，此时用 _______ 引导从
句，主句用 __________ 时态，从句
用过去进行时态。
一般过去
while
?总结
?1) when可指时间点, 又可指时间段, 从句中
可用延续性动词, 也可用非延续性动词。
?2) while总是指一个时间段, 从句中必须用延
续性动词。
3)当两个动作同时持续发生的时候,主句
和while引导的从句都用过去进行时.
e.g. I was watching TV while my sister was
listening to the music.
A: What were you doing at nine o’clock last Sunday morning?
B: I was sleeping. How about you?
A: I was doing my homework.
