一般过去时
A．结构
① be动词（is，am, are）→ was/were 主语 + 谓语
②实义动词→相应的动词过去式
①表示过去的事实或状态。
He was very busy an hour ago.他在过去的一小时非常忙碌。
I was eight years old last year. 我去年8岁。
②表示在过去某个时间内所作的事情，常和表示过去的时间状语连用。
She bought many books yesterday .昨天她买了很多书。
I played table tennis with my friend last Monday. 上周一我和一个朋友打了乒乓球。表示过去的时间状语，有：yesterday，last week,last year,two days ago,...
巧记一般过去时：
1.Be动词在一般过去时中的变化：
肯定句：主语+ was/were +其他He was at home yesterday.
⑴am 和is在一般过去时中变为was。（was not=wasn’t）
⑵are在一般过去时中变为were。（were not=weren’t）
否定式：主语+ was/were not +其他He wasn’t at home yesterday.
一般疑问句：was/were+主语+其他Was he at home yesterday?
肯定回答用“Yes, 主语＋was／were．”；
否定回答用“No,主语＋wasn't／weren't．”。
2.句中没有be动词的一般过去时的句子
肯定式: 主语+动词过去式+其他
Jim does homework every day. 一般现在时
Jim did homework yesterday. 一般进去时
否定句：主语+did not（didn’t）+动词原形+其他
Jim did homework yesterday.
Jim didn't do homework yesterday. (didn't +动词原形)
一般疑问句：Did + 主语 +动词原形+ 其他？
回答：Yes, 主语 + did.
No, 主语 + didn’t
Jim did homework yesterday.
Did Jim do homework yesterday? (在句首加did，句子中的动词过去式变回原形) 特殊疑问句：⑴疑问词+did+主语+动词原形？
Jim did homework yesterday.
Did Jim do homework yesterday?
What did Jim do yesterday? (疑问词+一般疑问句？)
⑵疑问词当主语时：疑问词+动词过去式？如：Who went to home yesterday? When were they in the park? ---Just now.
When did they live in Beijing? ---Last year.
What did you do last night? ---I did my homework.
Where did you go last week? --- I went to Shanghai with my parents.
一般过去时四大公式
1.问动作
What did…do +过去的时间？
….+动词过去式(尽量避免用went…的短语)
What did Miss Tang do last night?
She watched TV.
2.问位置
Where did…go+过去的时间？
…went to +地方或… went to the +地点。(其中go to school与go home 是例外的)
Where did you go on your holiday?
I went to Canada on my holiday.
Where did you go on your holiday?
We went to the cinema
3.问交通
How did …go /与go有关的短语？
…+went+交通方式
How did Coco go?
Coco went on foot
How did Coco go to school?
Coco went on foot.
4.When did … go/与go有关的短语？
…went +过去的时间
When did…+动词（原形）？
…+动词过去式+过去的时间
When did she go?
She went last Sunday.
When did she go to Beijing
She went last winter holiday.
B．动词的过去式
动词有规则动词和不规则动词之分。规则动词的过去式都是以-ed结尾，而不规则动词的过去式是没有规则。
①一般情况下，在动词原形后直接加ed。如：wanted，played。
②以不发音的字母e结尾的动词，直接加d。如：hoped，lived。
③重读闭音节单词需双写最后一个辅音字母，再加ed。如：stopped, shipped。
④以辅音字母+y结尾的动词变y为i，再加ed。如：studied，worried。
⑤有些动词不符合上面的规则，需要特殊记忆。
am(is)-was, are-were, go-went, eat-ate, swim-swam, buy-bought, see-saw, break-broke,
