初三英語語法重點-過去完成時-詳解過去完成時一、教材典句1.Bythetimelgotoutside,thebushadalreadyleft.當(dāng)我出去時,公共汽車已經(jīng)離開了。2.BythetimeIwalkedintoclass,theteacherhadstartedteachingalready.當(dāng)我走進(jìn)教室時,老師已經(jīng)開始講課了。仔細(xì)觀察以上兩句,不難發(fā)現(xiàn)時間狀語從句都用了一般過去時態(tài),主句都是發(fā)生在“過去的時間之前”,即過去的過去,應(yīng)用過去完成時。二、語法詳解（一）過去完成時的定義及構(gòu)成1.過去完成時定義：表示在過去某個時間或動作之前已經(jīng)發(fā)生或完成了的動作,它表示動作所發(fā)生的時間是“過去的過去”。2.過去完成時的構(gòu)成過去完成時由“助動詞had+動詞的過去分詞”構(gòu)成(had用于各種人稱和數(shù))。例如:Shehadarrivedatthevillagebefore8o'clocklastnight.她在昨晚8點之前就到達(dá)了這個村莊。（二）過去完成時的句式結(jié)構(gòu)肯定句：had+過去分詞否定句：hadn’t+過去分詞一般疑問句：had提前，放于句首（三）過去完成時的時間狀語1.介詞by(theendof)/before+過去的時間例如:Theyhadcollectedover1,000stampsbytheendoflastmonth.截至上個月末,他們已搜集了1000多張郵票。2.與when,bythetime,before,after等引導(dǎo)的時間狀語從句連用。例如:WhenIgotupthismorning,myfatherhadalreadygonetowork.今天早上我起床時,我的爸爸已經(jīng)去上班了。3.用于told,said,asked,heard,thought等動詞的賓語從句中,從句的動作發(fā)生在主句動作之前。例如:Shesaidthatshehaddividedthestudentsintotengroups.她說她已經(jīng)把學(xué)生分成了十個組。注意：

過去完成時和現(xiàn)在完成時一樣,當(dāng)句中有表示一段時間的狀語時,謂語動詞必須用延續(xù)性動詞,不能用短暫性動詞。例如:Hispetdoghadbeendeadforthreemonthsbytheendoflastweek.截至上個周末,他的寵物狗已經(jīng)死了3個月了。三、語法專練（一）單項選擇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、動詞填空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）真題訓(xùn)練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
