初中英语课件：八种时态.ppt

TheRevisionofTenses,Ms.Zhou,课件的使用说明,本课件主要是针对各种时态的综合复习。中外文化的差异使英语的表达增加了许多难度，特别是时态的变化。汉语中只有时间的变化，而英语中的谓语也要随之变化。本课件重点就8种时态（中学16种时态）加以综合，使学生们通过眼观，耳听，口述之后达到心中有数。首先，通过汉英表述的差异，引导学生说出中学所学的8种时态。其次，通过学生自我总结，运用图中对话，以及时空表达使学生们对各种时态进一步了解，再通过进一步即时操练，达到熟练掌握之目的。然后对各种时态重新回顾，再通过延伸练习达到进一步巩固之目的。最后，答“记者”问。相信通过各种时态的综合复习,学生们写作时他们的时态失误率定会大大减少.谢谢,TheTensesoftheVerbs,No.1ThePresentIndefiniteTense,No.3TheFutureIndefiniteTense,No.2ThePastIndefiniteTense,No.4TheFuture-In-The-PastTense,No.5ThePresentContinuousTense,No.8ThePresentPerfectTense,No.6ThePastContinuousTense,No.7ThePastPerfectTense,No1.ThePresentIndefiniteTense,A.DefinitionItexpressesanactionorstateinthepresentatthetimeofspeaking.Asthesquareframebelow.,DoyouknowwhatIoftendo?,Youusuallygo.,Past,Now,Future,B.Markwordsandphrases.sometimes,often,always,usually,seldom,every,never.,C.Basicstructures1.s+v+p:Yourestudents.2.s+v:Thestudentsoftengotoschoolonweekdays.3.Therebe:Thereisadognearthedoor.,A.DefinitionItexpressesanactionthathappenedinthepast.,B.Markwordsandphrases.yesterday,twodaysago,lastweek,in1999.,No2.ThePastIndefiniteTense,Likethepicturebelow.,Past,Now,WhatdidIdo?,1.s+was/were+p：Youwerepupilsin2000.2.Therewas/were.:Therewasapolicecarinourschoolyesterday.3.s+v(pasttense):YaoMingwenttoNBAtwoyearsago.,C.Basicstructure,Ialsoknow!,No.3TheFutureIndefiniteTense,A.DefinitionItexpressesanactionthatwillhappeninthefuture.,Iwillbeakingoftheworld.,Asthedottedlinebelow.,Now,Future,B.Markwordstomorrow,next,in2008,C.BasicStructure1.S+will/shall+V:Wewill/shalltalkaboutMr.Zhunexttime.2.S+begoingto+V:Wearegoingtoplaybasketball.3.S+beaboutto+V:Itisabouttoraintomorrow.4.S+beto+V:Imtobeadoctornextyear.,No.4TheFuture-In-The-PastTense,Itexpressesanactionthatwillhappeninthefuturefromthenon.,A.Definition,Lookatthedoubledottedlinebelow,Past,Now,Future,Comeon!,NexttimeIwouldcatchyou!,1.S+should/would+VHetoldmethatIshouldsucceed.2.S+was/weregoingto+VTheyweregoingtohaveameeting.3.S+was/were+aboutto+VThetrainwasabouttoleave.4.S+was/were+to+VHesaidhewastoleaveschool,B.BasicStructure,A.DefinitionItexpressesanactionthatcontinuesoveraperiodoftimenow.,DoyouknowwhatImdoing?,No.5ThePresentContinuousTense,Astheverticallinebelow.,Past,Now,Future,S+be+Ving1.WearetalkingaboutLesson2.2.Listen！whoisspeaking?,B.Markwordsandphrases,now,look,listen,thesedays,C.Basicstructure,Iknow!,A.DefinitionItexpressesanactionthatcontinuesoveraperiodoftimewhichisinthepast.Lookatthedoubleverticallinebelow.,WhatwasIdoingyesterday?,No.6ThePastContinuousTense,Past,Now,Future,S+was/were+Ving1.Jimwasdoinghishomeworkatthistimeyesterday.2.Wewereplayingcardsat9:00yesterday.,atthistimeyesterday,atthistimeoflastyear.at9:00yesterday.,C.Basicstructure,B.Markphrases,Understand?,Itexpressesanactionthatisfinishedinthepast,maybeitcangoon.Justlikedoublepitcharcsbelow.,No.7ThePastPerfectTense,A.Definition,S+had+V(pastparticiple)1.Theteacherhadbeentherewhenwearrived.2.Wehadlearned2000wordsbytheendoflastyear.,B.BasicStructure,Past,Now,Future,already,yet,never,ever,just,before,since,No.8ThePresentPerfectTense,A.Definition,Itexpressesanactionthatisfinishedatpresent.Butmaybeitcancontinue.,B.MarkWords,Past,Now,Future,Ihavefinishedmyhomework.,Likethepitcharcbelow,S+have/has+V(pastparticiple)1.YaoMinghasgonetotheUSA2.IhaveneverbeentoJapan.3.Wehavefinishedeighttensesnow.,Letstalkabouttheexercisesbelow.,C.Basicstructure,Iknowwell!,一.Accordingtothepicturesabove.Fillintheblanks.Look,he_(wait)forabus.There_(be)asportsmeetingnextweek._youoften_(go)tothecinema?Tom_already_(borrow)manybooks.What_you_(do)atthistimelastweek?Hesaidhe_(visit)hisgrandmothernextweek.They_(plant)alotoftreesalongtheriveryesterday.8.Hesaidhe_(be)toShanghaibefore.9.Atpresentwe_(finish)allthelesson.,Exercise,iswaiting,willbe,Do,go,has,borrowed,were,doing,wouldvisit,planted,hadbeen,havefinished,1.whatareMrandMrsBlackdoing?-They_teainthegarden.A.aredrinkingB.drankC.havedrunkD.drink2.Imsorryyouvemissedthetrain.It_10minutesago.A.leftB.hasleftC.hadleftD.hasbeenleft3.Idontknowifhisuncle_.-Ithinkhe_ifitdoesntrain.A.willcome;comesB.willcome;willcomeC.comes;comesD.comes;willcome4.howmanytimes_y
