三、语法解析
过去进行时的主要用法
一） 概念和用法：
过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was /were + V-ing。常与表示过去的时间状语连用，如：last night, last Saturday等；或者与when, while, as引导的过去时间状语连用。例如： We were watching TV from seven to nine last night. 昨天晚上七点到九点的时候我们在看电视。 What was he researching all day last Sunday? 上周日他一整天都在研究什么？
二）过去进行时可以表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示。如：
What was she doing at nine o„clock yesterday? 昨天晚上九点她在做什么？ (介词短语表示时间点)
When I saw him he was decorating his room. 当我看见他的时候他正在装饰房间。 (when从句表示时间点)
三）在复合句中，如果主要动作和背景动作都是延续的或同时发生的，那么主从句的动词都可用过去进行时。例如：
While he was waiting for the bus, he was reading a newspaper.他边等车边看报。 (两个动作都是延续的)
He was cleaning his car while I was cooking. 他擦车时我在做饭。(两个动作同时进行)
四） 通常不能用于过去进行时的动词主要有：agree, is,am,are, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。例如：
误：I was knowing the answer.
正：I knew the answer. 我知道答案。
误：I wasn„t understanding him.
正：I didn„t understand him. 我不明白他的意思。
五）句型
肯定句：主语+was/were+doing+其它
否定句：主语+was/were+not+doing+其它
一般疑问句及答语：Was/Were+主语+doing+其它
答语：Yes,I was./No,I wasn't.
特殊疑问句：特殊疑问词+was/were+主语+doing+其它
六）when 和while的用法区别 两者的区别如下：
①when是at or during the time that, 既指时间点，也可指一段时间；while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。
②when 说明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 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。
③由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如：
a. When the teacher came in, we were talking. 当此句改变主从句的位置时，则为： While we were talking, the teacher came in.
b. They were singing while we were dancing.
④when和while 还可作并列连词。when表示“在那时”；while表示“而，却”，表对照关系。如：
a. The children were running to move the bag of rice when they heard the sound of a motor bike. 孩子们正要跑过去搬开那袋米，这时他们听到了摩托车的声音。
b. He is strong while his brother is weak. 他长得很结实，而他弟弟却很瘦弱。
when一般接短暂性动词（如jump,cut等），而while接延续性动词（如wait,walk)，常用进行时态
如果主句谓语动词表示的是短暂动作，从句时间状语指一段时间，则when，while，as都可用as和when可与非延续性动词连用，而while只能与延续性动词连用as和when都可用来指一段时间，但as强调主句和从句表示的动作同时发生，而while强调主句表示的动作是在while从句的动作延续中发生的。
She sang as she went along. 她边走边唱歌 。
She sang while she went along. 她走路时一直在唱歌 。
