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 isYou're == You are Who's == Who is They're ==They areWhere's ==Where isHe's ==He is She's ==She is It's == It isisn't==is not aren't==are not2)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 washguess 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 fiveminutes, on Sundays等时间状语连用,eg. He has a brother.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 .eg. Here comes the train.4.在时间和条件状语从句中代表一般将来时 .eg.I'll go with you if you are free tomorrow.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?简略回答.(肯)Yes, 主语 +did (否)No , 主语 + didn't.用法:1.主要用于过去某个时间发生的动作或状态.eg. My father was at work yesterday.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。
[注意]上述动词过去式究竟是以ought[:t]还是aught[:t]结尾,只要记住“有a则a,无a则o”即可。
即:原形中有a的,过去式变为aught,否则为ought。
V.以eep结尾的动词,常将eep改为ept构成过去式。
例如:keep —kept, sleep—slept, sweep—swept等。
