初中英语全部时态

一般现在时

A:一般现在时通常表示目前阶段经常发生的动作或存在的状态。

结构:

1）be动词的第一人称单数为，第三人称单数为，其他人称为。

有一顺口溜体现了它的用法：我用am ，你用are ，is 用于他，她，它, 单数is，复数are.

肯定式:主语+ am /is/are +其他

否定式:主语+ am/is/are +not + 其他

疑问式:Am /Is /Are + 主语+ 其他?

简略回答: (肯) Yes,主语+ am/ is /are

(否) No,主语+ am /is/are not

缩写形式: I'm == I am That's ==That is We're ==We are What's== What is

You're == You are Who's == Who is They're ==They are Where's ==Where is

He's ==He is She's ==She is It's == It is

isn't==is not aren't==are not

2）行为动词（实义动词）除主语是第三人称单数外，都用动词原形，主语是第三人称单数时，在动词词尾加-s或-es 。

“动词第三人称单数”的加法即“如何从动词原形变为第三人称

单数”

1、一般情况加s.

2、以o, s, x, ch, sh 结尾加es.

3、以“辅音字母+y”结尾改y为i +es

写出下列动词的第三人称单数：

study play go come help teach lie listen begin open sit throw wash

guess cut run relax beat eat

肯定式:主语+动词原形/动词的第三人称单数

否定式:主语+助动词don't/doesn't +动词原形+其他

疑问式:Do/Does+主语+动词原形+其他

简略回答:(肯)Yes,主语+do/does (否)No,主语+do/does not

缩写形式: don't == do not doesn't ==does not

注意：have的第三人称单数为has

用法：

1.表示事实,现状,性质或经常的,习惯的动作,常与often, usually, always, sometimes, today,every day,once a week, every five minutes, on Sundays 等时间状语连用,

2.表示普遍真理. eg. The earth goes round the sun.

3.表示在现在时间里所发生的一个动作.

4.在时间和条件状语从句中代表一般将来时.

一般过去时

一般过去时表示过去发生的动作或存在的状态，一般过去时通常由动词的过去式表示。

结构：

1.动词的第一、三有称单数用,其他人称用,其肯定式,否定式,疑问式和简略回答形式与一般现在时相似。

2.行为动词的过去式分为规则和不规则两种, 规则动词的过去式是在动词后加或,不规则动词参照不规则动词表,需要专门记忆。

肯定式:主语+动词的过去式+ 其他eg. I got up at six this morning. 否定式:主语+ did not + 动词原形+ 其他eg. John didn't live here last year.

疑问式:Did + 主语+ 动词原形+ 其他eg. Did you see him a moment ago?

2.表示过去经常或反复发生的动作,常与often,always 等表示频度的时间状语连用.

eg. He always went to work by bus last summer.

3.和when等连词引导的状语从句连用.

eg. When she reached home, she had a short rest.

4.常与表示过去的时间状语, 如…ago, yesterday, last week, in the old days, when I was five years old, in 1995 等连用.eg.They began the work two months ago. Were you born in 1981? Yes, I was.

不规则中寻"规则"

英语中很多动词的过去式是不规则的，有些同学死记硬背，却效果不佳。我们不妨共同寻找一些不规则动词中的“规则”，这样记忆起来就会事半功倍了。

I．过去式与动词原形同形。例如：

let—let, put—put, hit—hit, read—read[red]等。

II．动词原形以ow／aw结尾，过去式常变为ew。例如：know—knew, grow—grew, throw—threw, draw—drew等。但是也有一些例外，例如：show—showed。

III．许多动词只要将动词原形中的元音字母i改为a，就可变为过去式。例如：

begin—began, give—gave, sing—sang, swim—swam, sit—sat, drink —drank, ring—rang等

但是win—won例外。

IV．有些动词的过去式以o(a)ught结尾。例如：

bring—brought, buy—bought, think—thought, catch—caught, teach —taught等。
