1、过去进行时的结构
2、过去进行时的基本用法
3、过去进行时与一般过去时的区别
考点一 过去进行时的结构
知识梳理

如：I was doing my homework at that time. (doing就是do的现在分词）
(2)一般疑问句：把was或were放于句首。
如：Were you doing your homework at that time?
(3)否定形式：was/were + not + doing.
如：They were not doing their homework at that time.
(4)过去进行时态常用时间状语：
at 8 o’clock last night, this time yesterday 等。
知识梳理
考点二 过去进行时的基本用法
(1) 过去某一时刻正在进行的动作或某一阶段内正进行的动作或动作频繁发生。
如：I was doing my homework at 9 o'clock p.m. last Sunday.
(2)某一动作发生时另一动作正在发生，其中一个在由when，as或while引导的时间状语从句中。
如：I was reading books while he was cleaning the floor.
(3) 表示一个动作正在进行时，另一个动作发生了。
如：They were having dinner when I got home.
(4) 表示过去将要发生的动作。
(5)用于宾语从句中。

知识梳理
考点三 过去进行时与一般过去时的区别
(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结束。如：
He was writing his composition last night. 他昨晚在写作文。(不一定写完)
He wrote his composition last night. 他昨晚写了一篇作文。(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。
如：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。
知识梳理
考点三 过去进行时与一般过去时的区别
(3) 一般过去时与always, forever, 等连用，表示“过去经常性、习惯性的动作”;而过去进行时与always, forever等连用，表示动作的重复，常带有感彩。如：
(4) 有时过去进行时可以替换一般过去时，一般过去时表示主语的行为是经过认真考虑的;而过去进行时表示一种随便或没有仔细考虑的行为。如：
I thought that he would agree with us. 我原以为它会同意我们的。
I was thinking of persuading him to follow my advice.
我想到了要说服他接受我们的建议。
He was always thinking of his work. 他总是一心想到工作。
