英语中，过去进行时表示过去某一时刻或某段时间正在进行或发生的动作，其基本构成形式为“was/were v.-ing”。下面我们一起来学习过去进行时的具体用法：
一、过去进行时的基本用法
1. 过去进行时常与at that time、this time yesterday、from eight to ten last night、at six thirty yesterday morning等时间状语连用。例如：
They were playing football at 8：30 last Sunday morning. 上个星期天上午八点半他们正在踢足球。
I was doing my homework at home from eight to nine yesterday morning. 昨天上午八点到九点我正在家里做作业。
2. 过去进行时的肯定形式为：主语 was/were v.-ing 其他。其中主语为单数时用was v.-ing形式，主语为复数时用were v.-ing形式。例如：
Mother was cooking this time yesterday. 妈妈昨天的这个时候正在做饭。
We were having dinner when the phone rang. 我们正在吃晚饭时电话响了。
3. 过去进行时的否定形式为：主语 wasn’t/weren’t v.-ing 其他。例如：
The students weren’t reading English at 6：30 yesterday morning. 昨天上午六点半学生们没在读英语。
This time yesterday Jack was not watching TV. He was repairing his bike. 昨天这个时候，杰克不是在看电视，而是在修理自行车。
4. 过去进行时的一般疑问句结构：Was/Were 主语 v.-ing 其他？例如：
Was he watching TV at nine last night？昨天晚上九点钟他正在看电视吗？
Were you playing basketball at four yesterday afternoon？昨天下午四点钟你们正在打篮球吗？
5. 过去进行时的特殊疑问句结构：特殊疑问词 was/were 主语 v.-ing 其他？例如：
What was Tom doing at 10∶00 yesterday morning？昨天上午十点钟汤姆在做什么？
What were the students doing when Miss Xu came in？当许老师进来时同学们在做什么？
▲过去进行时有时要根据上下文的语境来确定动词的时态，这是近年来命题的热点。例如：
—You were out when I dropped in at your house yesterday. 我昨天去你家看你时，你不在。
—Oh，I was waiting for a friend from Beijing at the train station. 噢！我在火车站等一个北京来的朋友。 ▲当“位移”动词go、come、start、leave等用过去进行时表示过去将来的动作，通常指计划或安排某时将要发生的动作。例如：
Mr Brown told us he was leaving there soon. 布朗先生告诉我们他很快就会离开那儿。
▲与频度副词always连用表示过去经常反复的动作，常常有埋怨、讨厌、赞扬或喜爱等感情，意为“老是”“总是”。例如：
My son was always forgetting things. 我的儿子总是丢三落四。（表示埋怨）
He was always helping others. 他总是帮助他人。（表示赞扬）
二、过去进行时与一般过去时的区别
1. 一般过去时常与典型的过去时间状语如yesterday morning/afternoon/
evening、last night/week/year/month、an hour ago、the day before yesterday、in 2008、long long ago 等连用。例如：
He went to bed at nine yesterday evening. 昨天晚上他是九点钟睡觉的。
We worked on the farm last year. 去年我们在农场干活。
2. 一般过去时表示过去发生的一个单纯事实，多侧重于动作的完成；过去进行时表示过去某时间或某一时刻正在进行或发生的动作，强调动作的进程和发展，但不一定完成。试比较：
She wrote an e-mail to her friend last night. 昨晚她给朋友写了封电子邮件。（说明“邮件已写完”）
She was writing an e-mail to her friend last night. 昨晚她一直在给朋友写电子邮件。（含有“邮件不一定写完”之意）
三、when与while在过去进行时中的区别
when与while从句都可与过去进行时的谓语动词连用，但它们之间是有区别的。when引导的时间状语从句与过去进行时连用时，指“当一个动作发生时，另一个动作正在进行”，从句中的谓语动词可以是延续性动词，也可以是非延续性动词，从句的动作既可和主句的动作同时发生，又可以在主句动作之前或之后发生；while引导的时间状语从句与过去进行时连用时，指“主句和从句的动作正在同时进行”，但从句的谓语动词必须是延续性动词。例如：
When my uncle came in， I was reading. 叔叔进来的时候，我正在看书。
He was singing while I was dancing. 他在唱歌时，我在跳舞。
