知识梳理
Language points
过去进行时
概念：过去进行时表示在过去某一时刻或某一时间段内正在进行或发生的动作。
结构：过去进行时由“was/were＋动词的 ing形式”
eg: Peter was reading a book in the library when the rainstorm came.
当暴风雨来临时，彼得正在图书馆读书。
标志：过去进行时的常用时间状语：过去进行时常用then (那时),
last night (昨晚), at that time (当时), at three yesterday (昨天3点), the whole morning (整个上午)，at this time yesterday (昨天这个时候)等作时间状语。
eg: What were you doing at 9:30 yesterday evening
昨天晚上9: 30 你在干什么？
It was raining heavily at this time yesterday.
昨天的这个时候雨正下得很大。
句式 构成
肯定句 主语+ was/were + 现在分词…
否定句 主语+ was/were+not + 现在分词…
一般疑问句 Was/Were + 主语+ 现在分词…
特殊疑问句 特殊疑问词+ was/were（＋主语）+现在分词…
各种句式：
eg: The students were having math class at three yesterday afternoon.
昨天下午3点学生们正在上数学课。
We were not playing basketball at that time.
那个时候我们没在打篮球。
Was he playing basketball this time yesterday
昨天这个时候他正在打篮球吗？
What was he doing at nine last night
昨天晚上9点他正在做什么？
用法：
1. 过去进行时常表示过去某一时刻或过去某一阶段内正在进行的动作。
eg: I was talking with my mother at this time yesterday.
昨天的这个时候我正和我妈妈聊天。
2. 过去进行时可表示两个动作同时进行。
eg: While I was doing my homework, my mother was cooking.
当我写作业时，我妈妈在做饭。
一般过去式和过去进行时的区别
（1）过去进行时强调动作在过去某时刻正在进行或持续，而一般过去时表示动作的完成。
eg: He was doing his homework last night.
他昨晚在写作业。(不一定写完)
He did his homework last night.
他昨晚写了他的作业。(已经写完)
（2）表示过去的状态、感觉及心理活动的静态动词(如be, like, love, hate, fear, own, hear, see, know, want, notice)可用于一般过去时，但通常不用于进行时。
eg: I hated it when a man spoke with his mouth full of food.
我讨厌人们说话时口里含着食物。
（3）一般过去时与 always, constantly, forever, continually 等连用，表示 “过去经常性、习惯性的动作”；而过去进行时与 always,
constantly, forever, continually 等连用，表示动作的重复，常带有
感彩。
eg: He always went to bed at nine. 他过去总是九点睡觉。
He was always thinking of his work. 他总是一心想到工作。
重点探究
when和while引导时间状语从句
Pair work
阅读教材上Grammar Focus 中的句子，注意when 和while所引导的状语从句的时态，同桌两人一组，说一说while和when句子中的动词的区别。
What were you doing at eight last night I was taking a shower.
What was she doing at the time of the rainstorm She was doing her homework.
What was he doing when the rainstorm came He was reading in the library when the rainstorm came.
What was Ben doing when it began to rain heavily When it began to rain, Ben was helping his mom make dinner.
What was Jenny doing while Linda was sleeping While Linda was sleeping, Jenny was helping Mary with her homework.
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.
while表示“在……的时候”、“在……期间”。
它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的
动作过程中。While从句中必须是表示动作或状态的延续性动词。
如：
The weather was fine while we were in Beijing.
She called while I was out.
如果主句的动作在从句的动作过程中发生，从句常用进行时。
如:
While we were swimming, someone stole our clothes.
Don’t talk so loud while others are working.
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。
