教学过程Step1.Warming-up:

1．T:What’s the weather like today?

S :略

2．T:What was the weather like yesterday?

S :略

3．T:What did you do last night？

S:略

Step2Lead-in:

1． e.g.: I was at home yesterday.

1）概念：过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；

2）通常与这些时间状语连用： yesterday, ago, the day before yesterday, last week, last (year, night, month…), in 1989, just now等等

e.g.：① He played football with his friends yesterday.

②We had a picnic last week.

…

…

3.一般过去时的基本结构：

A. 主语+be动词过去式（was、were） am\is—was are---were

a:主语是第一人称和第三人称单数以及人名时用was，如：I was ，he was She was ,it was ,Mary was 其他的主语是单数也都是用was 。

b:第二人称不管单数还是复数都用were ，如y：You were 其他当

主语是复数时都用were

B. 主语+行为动词的过去式如：I went to school by bus yesterday.

I played football with my friends last night.

C.动词过去式的变化：①原形词尾加ed ask--asked、 want---wanted

②以e结尾加d like---liked move---moved

③以辅音字母+y结尾的，变y为i+ed eg：study stuied ,(try--tryied fly---flyied); 词尾y前为元音字母直接加

ed(played stayed)

④以重读闭音节结尾，双写最后这个辅音字母再加ed stopped

⑤不规则动词过去式come—came run—ran have|has---had read-----read

4.一般过去时的否定形式：was/were+not ; 在行为动词前加didn't，同

时还原行为动词。如：you were not /I was not at home yesterday was not =wasn’t were not =weren’t

5.一般过去时的疑问句形式：was或were放在句首；用助动词do的过

去式did 提问，同时还原行为动词。

肯定回答：Yes,主语+was、were 或者Yes,主语+did

否定回答：No,主语+was\were not 或者no，主语+did not

如：Was there a boy in the classroom?

Were there some students in the classroom?

Did you have a good time in Summer Vacation?

Step3:Practise:

一、写出下列动词的过去式

is\am_________ fly_______ plant________ are ________

drink_________ play_______ go________ taste_________

put ______ cut plan_______ do ________

二、用be动词的适当形式填空

1. She _______ happy yesterday.

2. They _______ glad to see each other last month.

3. Helen and Nancy ________ good friends once upon

a time

4. The little dog _____ two years old last year. 5． You a good solider two years ago.

三、把下列句子改成一般疑问句以及否定句：

1．I was very busy last week.（改为一般疑问句并肯定回答）

_______ you very busy last week? Yes，I______.

2．There was an apple on the table.（否定句)

There ________ ______ an apple on the table.

3． Lucy did her homework at home.（改否定句）

Lucy _______ _______ her homework at home.

4．His father worked all day last Monday.（改一般疑问句）

______his father ________ all day last Monday?

Summary

一般过去时口诀:

一般过去时并不难，表示过去动作、状态记心间。

动词要用过去式，时间状语句末站。

否定句很简单，didn't 站在动词原形前，其它部分不要变。

一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站

最后一条请注意，动词过去式要牢记。
