Unit 3 Language in use优质课一等奖教案

初一下册一般过去时教案讲解

一、（1）专题讲解

1、定义：一般过去时表示过去某个时间里发生的动作或状态，常和表示过去的时间状语

连用；也可表示过去习惯性或经常性的动作和行为。

2、时间状语：yesterday , the day before yesterday , yesterday morning , just now , a moment

ago ,two days ago , last night / year / week , before 11:00 , in the past ，at that time等

3、使用情况：

（1) 表示过去某个时间发生的动作或存在的状态。

I got up at 7:00 yesterday. 我昨天7点起床。

(2) 表示过去经常或反复发生的动作。

He always went to work by bus last year. 去年他总是乘公交车去上班。

4.一般现在时的结构及句型变化

结构：一般现在时的结构主要有三种形式：

（1)、结构一（谓语动词为be动词时）

肯定句：主语+be(was，were)+其它. （注：am,is→was, are→were）

否定句：主语+be+not+其它.

一般疑问句：Be+主语+其它?

e.g. I was late yesterday.

e.g. They were in Bei jing last year.

I was not late yesterday.

They weren’t in Bei jing last year.

Were you late yesterday？

Were they in Bei jing last year？

Yes, I was.

Yes, they were.

No, I wasn't.

No, they weren’t

am和is在一般过去时中变为was。（was not=wasn’t）

are在一般过去时中变为were。（were not=weren’t）

(2)、结构三（谓语动词为实义动词时）

肯定句：主语+动词过去式+其它.

否定句：主语+ didn’t +动词原形+其它.

一般疑问句：Did+主语+动词原形+其它？

E.g. Li Ming studied English this morning.

E.g. We often played tennis in the past.

Li Ming didn't study English this morning.

We didn't often play tennis in the past.

Did Li Ming study English this morning？

Did you often play tennis in the past?

Yes, he did.

Yes, we did.

No, he didn't.

No, we didn't.

注：1.谓语动词为实义动词时，变否定句和一般疑问句一律找助动词did来帮忙（过

去时不分人称和单复数，都是加did或did not）

2.前面出现了助动词，后面的动词一律用原形。

3.变一般疑问句时，一问一答的关系当中，第一人称和第二人称要相互交换。

5.一般过去时的特殊疑问句：

结构：特殊疑问词

+一般疑问句？

特殊疑问词+did+主语+动词原形+其它？

特殊疑问词+was/were+主语+其它？

E.g. Where were you last night？

What did Jim do yesterday?

Where did you walk to yesterday？

1、动词过去式的规则变化

How did you find the job?

6、动词的过去式

(1)、一般词尾加-ed

stay--stayed

help -- helped

ask -- asked

look--looked

watch -- watched

(2）、以e结尾的只加-d

hope--hoped

love -- loved

dance -- danced

live→lived

（3）、末尾三个字母以“辅+元+辅”结尾，且为重读闭音节，应双写末尾的辅音

字母，再加-ed

Stop-- stopped

plan-- planned

drop -- dropped

beg -- begged

（4)、“辅音字母+y”尾，变y为i, 再加

-ed

carry -- carried

study -- studied

hurry -- hurried

2、动词过去式的不规则变化

（见书后表格）

7、口诀：

动词一般过去时，表示过去发生事；

be用was或用were, have,has变had；

谓语动词过去式，过去时间作标志；

一般动词加-ed，若是特殊得硬记。

否定句很简单，主语之后didn’t添；

疑问句也不难，did放在主语前；

如果谓语之前有did，谓语动词需还原；

动词若是was,were,否定就把not添。
