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

.Iwaslateyesterday..TheywereinBeijinglastyear.

Iwasnotlateyesterday.Theyweren’tinBeijinglastyear.

WereyoulateyesterdayWeretheyinBeijinglastyear

Yes,Iwas.Yes,theywere.

No,Iwasn'

t.No,theyweren’t

am和is在一般过去时中变为was。

(wasnot=wasn’t)

are在一般过去时中变为were。

(werenot=weren’t)

(2)、结构二(谓语动词为情态动词时)

(注意:

情态动词can,may,haveto等等。

肯定句:

主语+情态动词过去式+动词原形+其它.

否定句:

主语+情态动词过去式+not+动词原形+其它.

一般疑问句:

情态动词过去式+主语+动词原形+其它

.Theoldmancouldswim30yearsago.

Theoldmancouldn’tswim30yearsago.

Couldtheoldmanswim30yearsago

Yes,hecould.

No,hecouldn’t.

常用情态动词过去式如下:

can—could(能,会)

may―might(可以)

haveto―hadto(不得不)

shall―should(将要)用于第一人称单数

will―would(将要)用于所有人称

(3)、结构三(谓语动词为实义动词时)

主语+动词过去式+其它.

主语+didn’t+动词原形+其它.

Did+主语+动词原形+其它

.LiMingstudiedEnglishthismorning..Weoftenplayedtennisinthepast.

LiMingdidn'

tstudyEnglishthismorning.Wedidn'

toftenplaytennisinthepast.

DidLiMingstudyEnglishthismorningDidyouoftenplaytennisinthepast

Yes,hedid.Yes,wedid.

No,hedidn'

t.No,wedidn'

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didnot)

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:

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

.Wherewereyoulastnight

WhatdidJimdoyesterday

Wheredidyouwalktoyesterday

1、动词过去式的规则变化Howdidyoufindthejob

6、动词的过去式

(1)、一般词尾加-ed

stay--stayedhelp--helped

ask--askedlook--lookedwatch--watched

(2)、以e结尾的只加-d

hope--hopedlove--loved

dance--dancedlive→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--stoppedplan--planned

drop--droppedbeg--begged

(4)、“辅音字母+y”尾,变y为i,再加-ed

carry--carriedstudy--studiedhurry--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。
