Module9Lifehistory,一般过去时(三)我们已经学习了行为动词过去式的规则变化,即“动词原形+-ed”的形式。在本模块中,我们所学的动词过去式的构成方式较为独特,这类动词被称为不规则动词。不规则动词的过去式变化没有规律,需要单独记忆。1.不规则动词的过去式的构成。(1)过去式与原形相同:costcost,hithit,hurthurt,letlet,putput,cutcut,readread,beatbeat等。(2)过去式与原形不同:gowent,meetmet,comecame,taketook,eatate,seesaw,writewrote,swimswam,makemade,findfound,givegave等。,2.句型结构。含不规则动词的一般过去时的肯定句、否定句、一般疑问句以及特殊疑问句都与规则动词的句型结构相同。例如:Theyswaminthelake.他们在湖里游泳。Theydidntswiminthelake.他们不在湖里游泳。Didtheyswiminthelake?他们在湖里游泳了吗?Yes,theydid./No,theydidnt.是的,他们游了。/不,他们没游。,.单项填空(B)1.Didyouplaycomputergameslastnight?.Ididmyhomeworktillelevenoclock.A.Yes,IdidB.No,IdidntC.Yes,IwasD.No,Iwasnt(A)2.Mygrandmathenewspaperlastnight.A.readB.readsC.readingD.isreading(B)3.HetoschoollastMondaybecausehelosthisbike.A.walksB.walkedC.ridesD.rode,(C)4.WhenyoutoChina?InFebruary,1999.A.do;comeB.do;cameC.did;comeD.did;came(B)5.Headoctorwhenhelefthisschool.A.becomeB.becameC.becomesD.becoming,.根据句意用所给词的适当形式填空1.Didyousee(see)thefilmTitaniclastnight?No,butIwatched(watch)animportantfootballmatchonTV.2.Theboydrew(draw)manypicturesbeforeIcamehere.3.Whydoestheboylookupset?Becausehedid(do)somethingwrong.4.Helost(lose)hisdogyesterdayandcouldnt(cannot)finditanywhere.5.WangHongtaught(teach)Englishinajuniorschoolfiveyearsago.,
