首先,先回顾下一般过去时:
一般过去时:
意义:【1】表示过去的事实或状态。
I was twelve years old last year.我去年12岁。
My teacher was very angry two hours ago.我的老师两个小时之前非常生气。
【2】表示在过去某个时间内所做的动作经常与表示过去时间的状语连用。
Anna bought a dress yesterday. 安娜昨天买了一条裙子。
I went for a picnic with my family last weekend. 上周末,我和家人一起去野餐了。
过去进行时:
一、意义:【1】表示在过去某一时刻或者时间内正在发生或进行的动作或状态。
I was reading a book at this time yesterday. 昨天这个时候我正在看书。
【2】表示一个动作发生时,另一个动作正在进行,或一个动作正在进行时另一个动作突然发生。 I saw you while you were playing basketball. 我看见你的时候,你正在打篮球。主句为一般过去时,从句应使用过去进行时。

【3】也表示两个动作同时进行。

我在做家庭作业,我妈妈正在做晚餐。
二、结构
主语+was/were+ V-ing.+其他
如:I was watching TV then.那时我在看电视。
We were cleaning the house at this time yesterday.我们在打扫房子。
肯定句:主语+was/were+V-ing+其它.
如:She was watching TV at that time last night.
否定句:主语+was/were+not+V-ing+其它
如:She was not watching TV at that time last night.
一般疑问句:was/were+主语+V-ing+其它?
如:Was she watching TV at that time last night?
肯定回答:Yes,she was. 否定回答:No,she wasn't.
特殊问句:疑问词+was/were+主语+V-ing+其它?
如:What was she doing at at that time last night?
✅ -ing变化规则: 过去进行时标志词

when sb/sth.did sth.
while sb was doing sth
✅when和while的区别: 看一下这两个例句:
When my mother came back, I was watching TV.
当我妈妈回来的时候,我正在看电视。
While we were having a class, my mom was cooking at home.
当我们在上课的时候,我妈妈在家做饭。
从意思上来讲,when和while都可以翻译为"在......时候""当.....时候"
when: at or during the time that,既可以指时间点,也可以指一段时间。
while: during the time that, 只指一段时间。
✅【区别1】
因此when引导的从句中的动词可以是瞬间动词,也可以是延续性动词。
While引导的从句中的动词只能是延续性动词。
✅【区别2】
when 引导的从句的动作和主句的动作可以是同时也可以是先后发生。
While强调主句的动作在从句动作发生的过程中,或者主句和从句两个动作同时发生。
看看以下例句:While they are talking, the bell rang.在他们谈话的时候,上课铃响了。
I was watching TV when my mother came back yesterday evening.
昨天晚上妈妈回家的时候,我正在看电视。
