初中英语知识点微课课件 考点精讲 同课异构 26 过去进行时（13张PPT）

过 去 进 行 时
一、激趣导入
同学们，请读句子，体会动词的用法。
本次课我们一起来学习动词时态中过去进行时的用法。
They were having a class this time yesterday.
I was drawing a horse when the teacher came in.
While I was watching TV, she was doing some cleaning.
It was raining when they left the station.
二、考点剖析
1、命题思路
动词时态中过去进行时表示在过去某一时间内正在进行的动作。还可以表示过去某一点时间正在进行的动作或某段时间
内一直进行的动作。过去进行时的标志词:at 8 o’clock， last night, at that time, yesterday this time 等。考查时会把过去进行时放在某特定的语境中，或者放在when,?while,?as?等引导的时间状语从句中考查，还会考查过去进行时与一般过去时的比较。? ?
例1.过去进行时的结构：
(1)基本结构： 主语+was/were+动词现在分词+其它
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 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。
例2.现在进行时的基本用法 ：
(1). 过去某一时刻正在进行的动作或某一阶段内发生或频繁发生。（at this time yesterday, at that time ）
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：He played when I was studying.
(4) 表示过去将要发生的动作
如：She told us Mr.Li was arriving here.
(5)用于宾语从句中
如：Could you tell me what the children were doing at
seven thirty last night?
例3.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完成。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。
(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：
He always got up at six. 他过去总是六点起床。
He was always thinking of his work. 他总是一心想到工作。
(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。
