1沪教版初二下Unit8语法:过去进行时讲解及练习一、定义:过去进行时表示过去某一时刻正在进行的动作或两个在某一相同时间点内同时发生的动作或过去某一阶段一直在进行的动作。二、结构:1、肯定:was/were+doing(现在分词)2、否定:was/werenot+doing(现在分词)3、疑问:was/were+主语+doing(现在分词)三、用法1.表示过去某一阶段一直在进行的动作。常用的时间状语thismorning,thewholemorning,alldayyesterday,fromninetotenlastevening等。(1)WewerewatchingTVfromseventoninelastnight.昨天晚上七点到九点的时候我们在看电视。(2)WhatwasheresearchingalldaylastSunday?上周日他一整天都在研究什么?2.表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示如when,while等(1)Whatwasshedoingatnineo'clockyesterday?昨天晚上九点她在做什么?(2)WhenIsawhimhewasdecoratinghisroom.当我看见他的时候他正在装饰房间。3.在复合句中,如果主要动作和背景动作都是延续的或同时发生的,那么主从句的动词都可用过去进行时。(1)Whilehewaswaitingforthebus,hewasreadinganewspaper.他边等车边看报。(两个动作都是延续的)(2)HewascleaninghiscarwhileIwascooking.他擦车时我在做饭。(两个动作同时进行)四、过去进行时和一般过去时的区别1.两者都表示过去发生的动作,但过去进行时表示一个过去正在进行的动作,而一般过去时则表示一个过去已经发生的动作。HewenttoBeijingtheotherday.(带具体时间)Hesmokedalottwoyearsago.(过去行为)2Whenhewasaboy,hewouldoftengothere.(叙述过去)Whatwereyoudoingat8:30lastnight?(过去某时刻正在发生)Iwastypingaletterlastnight.昨晚我在打一封信。(可能没打完)Itypedsomeletterslastnight.我昨晚打了一些信。(已经打完)Iwasreadingthebookatthattime.(未读完,“读”的片段)Ireadthebookyesterday.(已读完,表整个“读”)五、when和while的用法区别1.when是atorduringthetimethat,既指时间点,也可指一段时间;while是duringthetimethat,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词。2.when说明从句的动作和主句的动作可以是同时,也可以是先后发生;while则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。3.由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如:(1)Whentheteachercamein,weweretalking.当此句改变主从句的位置时,则为:(2)Whileweweretalking,theteachercamein.(3)Theyweresingingwhileweweredancing.过去进行时练习题一、选择题。1.I______cookedamealwhenyou_____me.A.cooked,wereringingB.wascooking,rangC.wascooking,wereringingD.cooked,rang2.Hesaidhe_____todrawaplaneontheblackboardatthattime.A.triesB.triedC.wastryingD.willtry3.Whileshe______TV,she______asoundoutsidetheroom.A.waswatching,washearingB.watched,washearing3C.watched,heardD.waswatching,heard4.They_____afootballgamefrom7to9lastnight.A.werewatchingB.watchC.watchedD.arewatching5.Whatbook____you______whenI____youatfouryesterdayafternoon?A.did,read,wasseeingB.did,read,sawC.were,reading,sawD.were,reading,wasseeing6.ItwasFridayevening.Mr.andMrs.Green_____readytoflytoEngland.A.aregettingB.getC.weregettingD.got7.LeiFeng_____always_____ofotherswhenhe______inthearmy.A.is,thinking,wasB.was,thinking,isC.did,think,isD.was,thinking,was8.Agirl______mypenfalloffthetablewhenshe_____me.A.saw,passedB.wasseeing,passedC.wasseeing,passedD.wasseeing,waspassing9.We____forTomattenlastSunday.Heoftenkeptus______.A.werewaiting,waitingB.werewaiting,waitC.waited,waitingD.waited,wait10.He____hisfatheronthefarmthewholeafternoonlastSaturday.A.helpsB.wouldhelpC.washelpingD.ishelping11.Whilemother_______somewashing,I_____akiteforKate.A.did,madeB.wasdoing,madeC.wasdoing,wasmakingD.did,wasmaking12.“_______youangrythen?”“they______toomuchnoise.”A.are,weremakingB.were,weremakingC.are,madeD.were,made13.He____somecookingatthattime,so_____meA.did,heardB.did,didn’thearC.wasdoing,heardD.wasdoing,didn’thear14.ThistimeyesterdayJack_____hisbike.He_____TVA.repaired,didn’twatchB.wasrepairing,watchedC.repaired,watchedD.wasrepairing,wasn’twatching415.Hisparentswantedtoknowhowhe_____onwithhisnewclassmates.A.wasgettingB.getsC.isgettingD.willget二、用动词的适当形式填空一。1.Whilewe__________(wait)forthebus,agirl__________(run)uptous.2.I__________(telephone)afriendwhenBob__________(come)in.3.Itwasquitelateatnight.George__________(read)andAmy__________(play)herneedlewhenthey__________(hear)aknockatthedoor.4.We__________(test)thenewmachinewhentheelectricity__________(go)off.5.She__________(notwant)tostayinbedwhiletheothers________________(all,work)inthefields.6.Whilemother________(put)Cathytobed,thedoorbell________(ring).7.AsI__________(walk)inthepark,it__________(begin)torain.8.Evenwhenshe___________(be)achildshe__________(already,think)ofbecomingaballerina(芭蕾舞演员).9.Whenthebellrang,jenny_____(wait)inherseat.10.She_____(make)herdressthewholeafternoon.三、用动词的适当形式填空二。1.I_____(have)mybreakfastathalfpastsixyesterdaymorning.2.Mary_____(go)overherlessonsfromsixtosevenlastnight.Johnandpeter____(do)thesamething.3.What_____you___(do)atthattime?We_____(watch)TV.4.Wasyourfatherathomeyesterdayevening?Yes,hewas.He_____(listen)totheradio.5.They_____(notmake)amodelshipwhenIsawhim.6.---_____they____(have)ameetingat4yesterdayafternoon?---No,they_____.They_____(clean)theclassroom.7.______it______(rain)whenyouleftschool?Yes,it____.(No,it____)8.What_____yourfather_____(do)whenhewasyourage?9.Oneday,Edison_____(wait)foratraintoarrive,andsuddenlyalittleboyrantothetrack(轨道)toplay.10.HeaskedmeifI______(go)fishingthatafternoon.5四、翻译。1.昨天这个时候你们英语老师在做什么?她在和一些家长谈话吗?2.当我离开的时候他正在画一幅世界地图。3.当你看见他们的时候他们在干什么?他们在打扫教室。4.那时二班的学生没在操场上踢足球,他们在打篮球。5.一天,母亲下班回家的时候,约翰在给一个朋友写信。6.上周五一下午,学生们在干什么?他们一直在往墙上贴海报。7.昨天这个时候,一些学生在植树,一些学生在给小树浇水。8.老师走进教室的时候,学生们正在谈论当天的新闻。9.老虎等猴子的时候,他听到一个声音。10.今天上午放学的时候在下雨吗?是的,天正下着大雨。答案:一、选择题。BCDACCDAACCBDDA二、用动词的适当形式填空一。1.werewaiting;ran2.wastelephoning;came3.wasreading;wasplaying;heard4.weretesting;went5.didn’twant;wereallworking6.wasputting;rang7.waswalking;
