初三英语语法重点过去完成时详解全套

初三英语语法重点-过去完成时-详解过去完成时一、教材典句1.Bythetimelgotoutside,thebushadalreadyleft.当我出去时,公共汽车已经离开了。2.BythetimeIwalkedintoclass,theteacherhadstartedteachingalready.当我走进教室时,老师已经开始讲课了。仔细观察以上两句,不难发现时间状语从句都用了一般过去时态,主句都是发生在“过去的时间之前”,即过去的过去,应用过去完成时。二、语法详解（一）过去完成时的定义及构成1.过去完成时定义：表示在过去某个时间或动作之前已经发生或完成了的动作,它表示动作所发生的时间是“过去的过去”。2.过去完成时的构成过去完成时由“助动词had+动词的过去分词”构成(had用于各种人称和数)。例如:Shehadarrivedatthevillagebefore8o'clocklastnight.她在昨晚8点之前就到达了这个村庄。（二）过去完成时的句式结构肯定句：had+过去分词否定句：hadn’t+过去分词一般疑问句：had提前，放于句首（三）过去完成时的时间状语1.介词by(theendof)/before+过去的时间例如:Theyhadcollectedover1,000stampsbytheendoflastmonth.截至上个月末,他们已搜集了1000多张邮票。2.与when,bythetime,before,after等引导的时间状语从句连用。例如:WhenIgotupthismorning,myfatherhadalreadygonetowork.今天早上我起床时,我的爸爸已经去上班了。3.用于told,said,asked,heard,thought等动词的宾语从句中,从句的动作发生在主句动作之前。例如:Shesaidthatshehaddividedthestudentsintotengroups.她说她已经把学生分成了十个组。注意：

过去完成时和现在完成时一样,当句中有表示一段时间的状语时,谓语动词必须用延续性动词,不能用短暂性动词。例如:Hispetdoghadbeendeadforthreemonthsbytheendoflastweek.截至上个周末,他的宠物狗已经死了3个月了。三、语法专练（一）单项选择1.Myuncle（）manycomicstripsbeforeheworkedasamanagerin2010.A.createsB.wascreatingC.wouldcreateD.hadcreated2.WhenIgottothebookingoffice,they（）outallthetickets.A.weresellingB.hadsoldC.wouldsellD.havesold3.We（）inourcompositionsbytheendoflastSunday.A.handB.hadhandC.handedD.hadhanded4.We'dlearned2,000Englishwords（）2015.A.inB.sinceC.byD.at5.Hesaidhe（）thefilmtwodaysago.A.hadseenB.hasseenC.sawD.seen6.（）Igotthere,theplanehadalreadytakenoff.A.AfterB.BeforeC.BythetimeD.BothBandC7.He（）methathehadfinishedhiswork.A.toldB.tellsC.hadtoldD.tell8.Bythetimehereturnedthebook,he（）itfortwodays.A.hasborrowedB.hadborrowedC.haskeptD.hadkept9.We（）ourbreakfastwhenanoldmancametothedoor.A.justhavehadB.havejusthadC.justhadD.hadjusthad10.-What'sup?-Imissedthetrain.BythetimeIgottothetrainstation,thetrain（）for10minutes.A.hadleftB.hasleftC.hasbeenawayD.hadbeenaway11.Bytheendoflastterm,Stephen（）computerscienceinauniversityfortwoyears.A.hasn'tstudiedB.doesn'tstudyC.willstudyD.hadstudied12.BythetimeIgottoschool,IrealizedthatImybackpackathome.A.hadleftB.hadforgottenC.leftD.forgot13.WhenIgottothecinema,themovie（）forfiveminutes.A.beganB.hadbegunC.hadbeenonD.hasbeenon14.Robertwasveryupsetthatmostofhisfriendswhenhe（）attheparty.A.left;hadarrivedB.hadleft;arrivedC.left;arrivedD.hadleft;hadarrived15.Thetrain（）whenhe（）tothestation.A.wereleft;weregettingB.hadleft;gotC.hadbeenaway;gotD.left;got二、动词填空1.BythetimeIreachedhome,mymother（）(cook)supperalready.2.Thesnow（）(stop)beforeIgotupthismorning.3.Bytheendoflastyearhe（）(teach)inthisschoolfortenyears.4.BythetimeI（）(get)intothestore,someone(buy)theskirtthatIwanted.5.Whenshe（）(wake)up,sherealizedthatshe(oversleep).6.Hetoldhismotherthathe（）(run)outofmoneytobuynewclothes.7.I（）(meet)Kateinthestreetbychance.We（）(notsee)eachotherforsixyears.8.Hedidn'tgotothemovieslastnightbecausehe（）(see)it.（三）真题训练1.-TuYouyoureceivedtheNobelPrizeforher（）ofartemisinin(青蒿素).-AndshewasthefirstChinesewhowontheprizeinscience.A.designB.thoughtC.inventionD.discovery2.-What'shappeningoverthere,dear?-Thebuildingisonfire.Can'tyouseetheblacksmoke（）abovethe（）building?A.rise;burningB.rise;burnedC.rising;burnedD.rising;burning3.Heisanhonestperson,sowhathesaidis（）.A.knowledgeableB.valuableC.comfortableD.believable4.Don'tknowwhereyourkids
