Unit6单元语法讲练过去进行时-外研版英语八年级上册

●单元语法精讲●过去进行时1.过去进行时的意义过去进行时是表示在过去某一具体时刻正在进行的动作，强调某一动作在过去某时正在进行。2.过去进行时的构成过去进行时的谓语部分由“was/were+现在分词”构成，was/were作助动词。过去进行时的肯定句变为一般疑问句时，将was/were提到句首，否定句时在was/were后加上not。Thealienwasvisitingthemuseumatthatmoment.→Wasthealienvisitingthemuseumatthatmoment?(一般疑问句)Thealienwasn'tvisitingthemuseumatthatmoment.(否定句)3.过去进行时的判断(1)一般情况下，句中用到表示具体动作且为可延续性的动词，同时句中用到表示在过去某一具体范围不大(从几分钟到半天左右)的时间状语，如atteno'clocklastnight,atthistimeyesterday,atthattime,from7to9lastSundaymorning等时，用过去进行时。TheYoungPioneerswereplantingtreesonahillatsixo'clockyesterdayafternoon.昨天下午6点那些少先队员在小山上种树。(2)在叙述过去差不多同时发生的两个动作，用到从属连词when或while时，如果一个动作是可延续性的表具体动作的动词，而另一个动作是不可延续性的动词，一般可延续的那个动词用过去进行时，而不可延续的那个用过去时。Whilethechildwasplayingbasketballontheroad,acarhithim.当那个孩子在路上打篮球时，一辆小汽车撞了他。4.过去进行时与一般过去时的区别过去进行时强调某一动作是在过去某时正在进行，一般用到的动词是表示具体行动，动作是可延续的，同时用到的时间状语表示的范围要小且具体；而一般过去时对谓语动词没有限制，用到的时间状语范围不受限制，一般过去时着重表示在过去做过，基本上是一个结束了的动作。表过去状态、抽象、不表具体动作行为的动词不用过去进行时，但可以用一般过去时。MrGreenwasmendinghisdaughter'sbikethismorning.今天早上格林先生正在修他女儿的自行车。(强调动作正在进行)MrGreenmendedhisdaughter'sbikethismorning.今天早上格林先生修了他女儿的自行车。(表明动作做过，并结束了)●过去进行时语法精练●习题一：用所给动词的过去进行时形式填空1.I__________(do)myhomeworkat8o'clocklastnight.2.They__________(watch)TVwhenIcalledthem.3.What__________you__________(do)atthistimeyesterday?4.She__________(notsleep)whenhermothercamehome.5.Thestudents__________(have)anEnglishclassfrom9to10yesterdaymorning.6.WhileTom__________(read),hissisterwasplayingthepiano.7.It__________(rain)heavilywhenwewentout.8.ThephonerangwhileI__________(take)ashower.9.We__________(wait)forthebusfrom7:00to7:30.10.He__________(drive)toworkatthattime.习题二：单项选择()1.What______atthistimeyesterday?A.didyoudoB.wereyoudoingC.areyoudoing()2.IsawLiMing______abookinthelibrary.A.readB.readingC.wasreading()3.Mymother______dinnerwhenIgothome.A.cookedB.wascookingC.cooks()4.They______footballfrom3to5yesterdayafternoon.A.playedB.wereplayingC.areplaying()5.Thesun______whenwestartedourjourney.A.shinedB.wasshiningC.shines()6.WhileI______tomusic,mybrotherwasdoinghishomework.A.listenedB.waslisteningC.amlistening()7.______you______TVat8lastnight?A.Were;watchingB.Did;watchC.Are;watching()8.He______hiscaratthatmoment.A.waswashingB.washedC.washes()9.Thechildren______inthegardenwhenitbegantorain.A.playedB.wereplayingC.areplaying()10.I______alettertomyfriendatthattime.A.wroteB.waswritingC.write习题三：用when或while连接句子1.IwaswatchingTV.Thelightwentout.→______2.Shewascooking.Thephonerang.→______3.Theywerewalkinginthepark.Theymettheirteacher.→______4.Hewasridinghisbike.Hefelloff.→______5.Wewerehavingdinner.Someoneknockedatthedoor.→______6.Theteacherwasexplainingthetext.Thebellrang.→______7.Iwasreadinganovel.Myfriendcalledme.→______8.Theywerediscussingtheplan.Themanagercamein.→______9.Shewassinging.Herbrotherwasplayingtheguitar.→______10.Thestudentsweredoingexercises.Theteacherwaswalkingaround.→______习题四：改正句中的错误1.Iwasreadabookwhenhecamein.2.Theywereplaybasketballat4yesterday.3.Whatdidyoudoingatthattime?4.Shewasn'twatchTVwhenIsawher.5.WhileIwasslept,someoneknockedatthedoor.6.Thechildrenwereswiminthepool.7.Hewerewritingaletteratthatmoment.8.Wastheywaitingforthebus?9.Iwasn'tunderstandingthelesson.10.Thesunwasshinedbrightly.习题五：过去进行时与一般过去时的选择()1.I______alettertomypenpallastnight.A.wroteB.waswriting()2.They______tennisfrom3to4yesterday.A.playedB.wereplaying()3.She______whentheaccidenthappened.A.droveB.wasdriving()4.We______ourgrandparentslastSunday.A.visitedB.werevisiting()5.He______hishomeworkat8o'clockyesterdayevening.A.didB.wasdoing()6.Thestudents______anexamyesterdaymorning.A.hadB.werehaving()7.I______myroomthismorning.A.cleanedB.wascleaning()8.They______dinnerwhenIarrived.A.hadB.werehaving()9.She______abeautifulsongattheparty.A.sangB.wassinging()10.We______TVwhentheearthquakehappened.A.watchedB.werewatching习题六：根据汉语意思完成句子1.昨天这个时候我正在打篮球。I__________basketballatthistimeyesterday.2.当我进来时，他正在写信。He__________aletterwhenIcamein.3.从两点到四点他们一直在开会。They__________ameetingfrom2to4.4.电话响的时候你在做什么？What__________whenthephonerang?5.昨天下午三点她正在洗衣服。She__________clothesat3yesterdayafternoon.6.我们到达时，他们正在吃晚饭。They__________dinnerwhenwearrived.7.当妈妈在做饭时，爸爸在看报纸。Whilemother__________,fatherwasreadingnewspapers.8.昨天晚上八点你在看电视吗？__________TVat8lastnight?9.下雨时，我们正在公园里散步。We__________intheparkwhenitrained.10.当时我没有在睡觉。I__________atthattime.答案习题一：1.wasdoing2.werewatching3.were;doing4.wasn'tsleeping5.werehaving6.wasreading7.wasraining8.wastaking9.werewaiting10.wasdriving习题二：1.B2.B3.B4.B5.B6.B7.A8.A9.B10.B习题三：1.Thelightwentoutwhen/whileIwaswatchingTV.2.Thephonerangwhen/whileshewascooking.3.Theymettheirteacherwhen/whiletheywerewalkinginthepark.4.Hefelloffwhen/whilehewasridinghisbike.5.Someoneknockedatthedoorwhen/whilewewerehavingdinner.6.Thebellrangwhen/whiletheteacherwasexplainingthetext.7.Myfriendcalledmewhen/whileIwasreadinganovel.8.Them
