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？
过去进行时中的 when 和 while
1. 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.
简单记：doing while doing
2. 过去进行时
1. 概念: 表示过去某一时刻或某段时间内正进行的动作。
2. 构成: was/were + 动词现在分词
3. 用法:
a: 表示某一时刻正进行的行为, 与特定的过去时间状
语连用,常见的时间有: at 8 last night, at this time
at that time, at that moment 等
e.g. What were you doing at 10 yesterday morning
I was writing a letter to my father at that moment.
b: 表示过去某段时间内正进行的动作。
e.g. We were building a house last winter.
They were waiting for you yesterday.
3.现在分词的构成
1) 一般动词在词尾加-ing, 如go--going。
2) 以不发音字母e结尾的动词, 先去掉e, 再加-ing。
come--coming make--making write--writing
3) 以重读闭音节结尾的动词, 如果末尾以一个
辅音字母结尾, 应先双写这个字母, 再加ing，
x和w结尾的除外。
如: get--getting swim--swimming
show--showing

4) 以字母y结尾的单词, 直接加ing。
如carrying、playing、studying。
5) 以字母ie结尾的动词, 变ie为y, 再加ing。
die → dying lie →lying
6) 以元音字母加e结尾, 或以e结尾, 且e发音的
动词, 直接加- ing。
see--seeing be--being
