过去进行时
情景感知
1.That night, I was sleeping when the ground shook very hard
那晚，我正在熟睡，这时地面突然剧烈震动。
2.By six o'clock the next morning, many buildings were still shaking.
第二天清晨六点，许多建筑仍在震动。
学习提示：感知教材原句可以发现，句1和句2都使用了过去进行时来表示过去正在发生的事情，谓语部分由“_________________+动词过去分词”构成。
要点精析
一．过去进行时的概念
一般来说，要表示过去某个时刻或时段正在进行或持续的动作，我们常使用过去进行时。
过去进行时的构成
肯定句： 主语+was/were+doing sth。
如：He was listening to music at this time yesterday.昨天这个时候，他正在听音乐。
否定句：主语+was not(wasn't)/were not(weren't)+ doing sth。
如：She was not painting then.那时她没有在画画。
一般疑问句：Was/Were+主语+doing sth 肯定回答：Yes,主语+was/were; 否定回答：No, 主语+wasn’t /weren’t
如：---Were you working on the farm at that moment
---Yes, we were./ No, we weren’t.
常用的时间状语
考点一：表示过去某个具体时间点正在发生的动作。常与具体的时间点状语连用。
标志词： at 8 o’clock yesterday, at that time, at this time yesterday, then, 以及 when/while 引导的时间状语从句。
I was doing my homework at 9 last night. （昨晚九点，我正在做作业。）
What were you doing when I called you （我给你打电话时，你正在做什么？）
考点二：表示过去某一段时间内持续进行的动作。
标志词： all the morning, the whole day, from 8 to 10 yesterday 等。
They were watching TV the whole evening.（他们整个晚上都在看电视。）
She was writing a novel last month. （上个月她一直在写一本小说。）
考点三：when 和 while 的典型场景（重中之重！）
这是中考最常见的考点，主要考察主从句时态的搭配。
①when引导的时间状语从句中，谓语动词可以是延续性动词也可以是非延续性动词；while引导的时间状语从句中，谓语动词必须是延续性动词。
【难点辨析】When 后既可接短暂性动作（用一般过去时），也可接延续性动作（用过去进行时）。While 后通常只接延续性动作。
We were talking when the teacher came in.
They arrived when/while we were having dinner.
②when引导的时间状语从句与过去进行时连用
主句 When从句
一般过去时 过去进行时
过去进行时 一般过去时
When I was waiting for the bus, the accident happened.
They were working when it began to rain.
③while引导的时间状语从句与过去进行时连用
主句 While从句
一般过去时 过去进行时
过去进行时 过去进行时
I saw an accident while I was walking on the road.
While she was falling, she was thinking about her cat.
考点四：用于故事或记叙文中描绘背景或场景。
在讲述过去的故事时，先用过去进行时描述背景，再用一般过去时叙述主要事件。
The sun was shining, and the birds were singing. People were sitting in the park. Suddenly, a child fell into the river.
五．过去进行时与一般过去时的区别
过去进行时：表示过去某一时刻或某时段正在发生或进行的动作。往往是正在进行且尚未完成的动作。
一般过去时：表示过去发生的动作或存在的状态，所表示的动作
时往往已经完成。
