实用雅思语法：过去进行时

语法的学习繁琐而又枯燥,市面上厚厚的语法书各式各样。说到雅思，不会语法也不行，那么到底应该怎么办呢？本文将为你解析第一个雅思实用语法，过去进行时。 那个时候我正在做什么呢？本文为你详细解析。

语法格式

subject + was/were + verb + -ing

Example: He was watching TV.

subject + was/were not + verb + -ing

Example: You weren't watching TV.

was/were + subject + verb + -ing?

Example: Were we watching TV?

The principal uses of the past continuous are listed below.

To set the "background scene" to an event or action. We use the past continuous to describe the background scene and the past simple to describe the event or action:

I saw him at 8 o'clock on Monday morning while he was waiting for the school bus.

I was shopping in a supermarket when I noticed a strange-looking man.

Past Continuous

We may have more than one background scene happening concurrently:

I was lying on my bed and listening to one of my favorite songs.

To emphasize activities which continued for some time but whose exact limits are not known and are not important. Notice the important difference between these two sentences:

For a while last year I was playing football for my local team and teaching English in the local elementary schools. (It doesn't indicate whether the actions were completed or not, or whether they happened concurrently)

Last year I played football for my local team and taught English in the local elementary schools. (It indicates that all of the actions are now complete, and probabley happened in that order)

Note: state verbs cannot be used in any continuous tense.
