2、体的过去时间状语。如:lastnight(week,month,year,century,etc.),yesterday,thedaybeforeyesterday,yesterdaymorning(afternoon,evening),in1999,twohoursago(oneweekago,treeyearsago,…)等等。一般过去时谓语动词的变化:1.be动词变成was或were2.实意动词变成过去式:(1)一般情况下,动词词尾加-ed,如:work---workedplay---playedwant----wanted
3、(2)以不发音的-e结尾动词,动词词尾加-d,如:live---livedmove----movedtaste---tastedhope---hoped(3)以辅音字母+y结尾的动词,把-y变为-i再加-ed,如:study---studiedcopy---copiedcry---criedcarry---carried(4)以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加-ed,如:stop---stoppedtrip--tripped清对清,浊对浊。元音后面还是浊,/t/、/d/后面发/id/。其余后面常发浊
4、。1. 在轻辅音[p][k][f][s]等后加ed读轻辅音/t/:asked cooked worked looked talked picked helped surfed2.在浊辅音[b][g][v][z][m]等及元音后加ed读浊辅音/d/:lived listened closed opened watered played3.在/t//d/之后读/Id/:add---added need---needed shout---shouted wait---waited
5、 want---wanted目前我们学过的在句子中做谓语的动词有两类:1.be动词am,iswasarewere2.实意动词除了be动词以外,都是实意动词。我们平常用的那些动词,例如,eat,look.teach.see.hear.等☆助动词dodiddo有两个词性,一个是助动词,做助动词的时候没有词义,只是协助动词。一个是实意动词,表示“做”的意思,比如dohomework否定句和疑问句一般过去时句中谓语动词是be动词的时候,否定句在be动词(即:was或were)后加not,一般疑问句把was或were调到句首。例:
6、Itwashotyesterday.Itwasn'thotyesterday.Wasithotyesterday?一般过去时句中谓语动词是实意动词的时候,变成否定句和疑问句,都要借助于助动词did,否定句在助动词did后面加not,疑问句用did来提问(注意:只要出现助动词,后面动词一定要还原)例:SheplayedcomputerlastSunday.Shedidn'tplaycomputerlastSunday.DidsheplaycomputerlastSunday?1.look2.live3.stop4.carry5.hope6.
