am,is→was,are→were)
否定句:
主语+be+not+其它.

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)

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。
