一般过去时——过去做某事

A、构成形式：主语+动词的过去式+其他。

注意：没有be动词的否定句和疑问句中，用didn’t否定和用did提问后，动词一定要用原形。

B、判断依据：

(1)be动词是was、were;

(2)动词加ed;

(3)有表示过去的时间状语，现在学过的常用的表示过去的时间状语有：just now，a moment，yesterday，last week，last night，last weekend，last year，last month，three days ago，two weeks ago，five years ago…

C、句型变换：

I was a teacher five years ago.

I wasn’t a teacher five years ago.

Were you a teacher five years ago?

Yes, I was. / No, I wasn’t.

They played many games yesterday.

They didn’t play many games yesterday.

Did they play many games yesterday?

Yes, they did. / No, they didn’t.
