一般过去时是表示过去经常或偶然发生的动作或存在的状态。

时间状语有∶just now;yesterday; last week; an hour ago; the other day; in 1982 等。Where did you go just now?She wasn't at home last night.
② 表示在过去一段时间内,经常性或习惯性的动作。
When I was a child, I often played football in the street.
Whenever the Browns went during their visit, they were given a warm welcome.

② 行为动词动词的过去式(动词过去式分规则变化与不规则变化)如 He was a teacher 3 years ago.
Jenny visited Shanghai last month. I went to school at 6:30 yesterday.
规则动词的过去式的构成遵循以下四个规则∶
a.直接在动词后加ed,例如help-helpedwant-wanted等
b.以不发音的字母e结尾时,去掉e加ed(即直接加d),例如like-liked;use-used等
c. 以辅音字母y结尾时,把y变成i再加ed,例如carry-carried; study-studied等;
d.以重读闭音节结尾,双写最后一个辅音字母再加ed,例如∶stop-stopped;shop-shopped等。不规则动词的过去式则需要特殊记,例如go-wentcome-came;buy-bought等。
写出下列动词的过去式
fallfell
wantwanted closeclosed comecame

2.否定形式
① was/ were + not
② didn't +动词原形
如∶ He wasn't a teacher 3 years ago.
Jenny didn't visit Shanghai last month. I didn't go to school at 6:30 yesterday. 3.疑问形式
① was 或were放于句首② Did + … + 动词原形……如Was he a teacher 3 years ago Yes, he was. / No, he wasn't.
Did Jenny visit Shanghai last month?Yes, she did. / No, she didn't.
