4种时态

“一般过去时”登台亮相

I. 一般过去时的概念

一般过去时表示过去某个时间发生的动作或存在的状态。常和表示过去的时间状语连用。如：last year, yesterday等；也可表示过去经常反复发生的动作，常和often, always 等频率副词连用。

例如：①I saw him in the street yesterday. 昨天我在街上看见他了。

②Li Mei always went to school on foot last year. 去年李梅总是步行上学。

II. 一般过去时的构成

我们主要来学习谓语动词为实义动词的一般过去时的构成。

动词过去式的构成：

(1)规则动词过去式的构成有四条规则：

①一般在动词原形末尾直接加上-ed。如：look-looked。

②以不发音的字母e结尾的动词，去e再加-ed。如：live-lived。

③末尾只有一个辅音字母的重读闭音节，先双写这个辅音字母，再加-ed。如：

stop-stopped。

④末尾是辅音字母+y结尾的动词，先变y为i，然后再加-ed。如：study-studied。

(2)不规则动词的过去式需特殊记忆。如：am(is)-was, are-were, go-went, come-came, take-took, have (has)-had等。

III. 一般过去时的几种句型

肯定句结构为：主语+动词的过去式+其它。如：He went to the toy store yesterday. 他昨天去玩具店了。

否定句结构为：主语+did not (didn't)+动词原形+其它。如：He didn't go to the toy store yesterday. 他昨天没去玩具店。

一般过去时的一般疑问句的构成：Did+主语＋动词原形＋其它？如：

1) -Did you go to Beijing last week?

-Yes, we did. (No, we didn't.)

2) -Did you meet the businessman before?

-No, I didn't. (Yes, I did.)

一般过去时的特殊疑问句的构成：疑问词＋did+主语＋动词原形＋其它？如：

1) -What did you do last night?

-I did my homework.

2) -Where did you go last week?

-I went to Shanghai with my parents.

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。

特殊疑问句也简单，疑问词加一般疑问句记心间。

最后一条请注意，动词过去式要牢记。
