Step 3 过去进行时
1. 基本概念：过去进行时表示在过去某一时刻或一段时间内正在进行的动作。这一特定的过去时间除有上下文暗示以外, 一般用时间状语来表示。
2. 结构 was / were ( nt ) + 动词-ing
3. 句式
肯定式：
I/He/She/It was wrking.
We/Yu/They/ were wrking.
否定式:
I/He/She/It was nt wrking.
We/Yu/They/ were nt wrking.
疑问式和简略回答:
Was I wrking?
Yes, yu were.
N, yu were nt.
Were yu wrking?
Yes, I was.
N, I was nt.
Was he/she/it wrking?
Yes, he/she/it was.
N, he/she/it was nt.
Were we/yu/they wrking?
Yes, yu/we/they were.
N, yu/we/they were nt.
注：
1) was nt常缩略为wasn’t; were nt常缩略为weren’t。
2) 一般过去时与过去进行时用法的比较: 一般过去时表示在过去某个时间发生过的动作或存在的状态, 而过去进行时则表示在过去某一时刻或某一段时间正在进行的动作。
例如:
David wrte a letter t his friend last night.
大卫昨晚给他的朋友写了封信。(信写完了。)
David was writing a letter t his friend last night.
大卫昨晚一直在给他的朋友写信。(信不一定写完。)

Step 4 过去进行时中的when和while
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？
请仔细观察下面的例句，然后补全空格中的内容。
① I was walking t schl when I saw a cat in a tree.
