现在进行时与过去进行时的区别语法中有两个时态,现在进行时和过去进行时,很多学生对这两种时态的区别不清楚,这里我把该如何讲解这两种时态总结一下。现在进行时和过去进行时的用法和区别现在进行时态一、现在进行时的构成现在进行时是由“助动词be+现在分词(doing)”构成。其中助动词be要根据句子主语的人称和数,分别变化为am,is或are三种形式。二、现在进行时的用法1.表示说话时正在进行的动作。(Look!Listen!Now或是上下文暗示了)如:Wearewaitingforyou.我们正在等候你。2.习惯进行:表示长期的或重复性的动作,而说话时动作未必正在进行的时候,用现在进行时态。如:WearereadingEnglishinthemorningthisweek.这个星期的早晨我们在读英语。SheislearningpianounderMr.Smith.他正在跟着史密斯先生学钢琴。3.与always,constantly(经常地),forever(永远地)等频度时间状语连用,表示反复发生的动作或持续存在的状态,往往带有说话人的厌烦、气愤、赞许等感情色彩。也要用现在进行时态。如:Youarealwayschangingyourmind.你总是改变主意。(生气)Sheisalwaysthinkingofothers.她总是为别人着想。(赞许)4、come,go,leave,arrive,fly等少数表示位置移动的动词,它们常用现在进行时态来表示将来的动作。如:HeisleavingShanghaiforGuangzhouthedayaftertomorrow.(他将于后天离开上海去广州。)三、现在进行时态的常用时间状语1、表示说话人说话时,常用now,Look!Listen!等。如:Look!Theyareplayingfootball.看!他们正在踢足球。2、表示“近阶段”时,常用thesedays,thisweek,thiswinter(spring,summer,autumn)等。如:Wearepreparingfortheexamsthesedays.这些天我们正在为考试作准备。四、注意事项:下列动词be(是),have(有),know(知道),love(爱),hate(恨),want(想要),like(喜欢),think(认为),believe(相信),wish(愿望、希望),understand(懂得、理解)等在表示状态、感情和感觉时候,不能表示一个正在进行的动作。过去进行时态一、过去进行时态的构成过去进行时态由助动词be的过去式was/were+现在分词(doing)构成,第一人称和第三人称单数用was,其余的都用were。二、过去进行时态的用法1、它表示在过去某一时刻或某一时间内正在进行或发生的动作,通常和表示过去的时间点的时间状语一起用。如:MyparentswerewatchingTVat8:00lastnight.昨晚八点钟时我的父母亲都在看电视。Theywereswimmingintheswimmingpoolthistimelastweek.上个星期的这个时候他们正在游泳池游泳。但在不少情况下,没有表示时间的状语,这时需要通过上下文来表示。2、在表示过去一个动作发生的时候,另一个动作同时也正在进行,那么持续时间长的动作要用过去进行时态。经常和when引导的时间状语从句连用。如:Whentheteachercamein,Iwassinging.老师进来时我正在唱歌。Whensomeoneknockedatthedoor,wewerehavingsupper.有人敲门时,我们正在吃晚饭。3、与always连用,表示一个不断重复的过去的动作。如:Hewasalwaysringingmeup.他老是给我打电话。三、过去进行时态的时间状语当句子中出现atthattime,then,atfouryesterdayafternoon,atthistimeyesterday,fromseventoteno’clockyesterdaymorning,以及when引导的从句时,一般情况下要用过去进行时态。如:Whatwereyoudoingattenyesterday?昨天10点你在干什么?四、注意事项go,come,leave,start,等词的过去进行时态,可以表示从过去的角度来看即将发生的动作。如:Sheaskedwhetherhewasstartingthenextday.她问他是否第二天就要动身。现在进行时和过去进行时的区别:1、两种时态在句子的构成上的区别是:现在进行时态用am,isare+现在分词(doing)形式。过去进行时态用was,were+现在分词(doing)形式。如:Sheissingingunderthetree.她正在树下唱歌。Shewassingingunderthetreeatthattime.她那个时候正在树下唱歌。2、两种时态在用法上的区别是:现在进行时态和过去进行时态虽然都用来表示动作正在进行。但是在表示说话时正在进行的动作时,要用现在进行时态。而在表示过去某个时段或过去某个时刻正在进行的动作时,就要用过去进行时态。如:Sheisplantingatree.她正在植树。(说话时正在植树)Whenareyoudoing/你在干什么?I'mdoingmyhomework.我正在做作业Shewasplantingatreeatthattime.(那时她在植树,此句指的是在过去那个时间里她正在植树)。Whatwereyoudoingat8:00lastnight?昨晚8:00你在做什么?IwaswatchingTV.我在看电视。过去进行时巩固练习:(聪明的你一定能全部做对)1.Simon_____________(make)amodelplaneat8:00a.m.2.Peter______________(do)hishomeworkatsevenlastnight.3、They____________(watch)afootballmatchfrom7:00to9:00lastnight.4.He_____________(try)todrawaplaneontheblackboardatthattime.5.Whatbook________you____________(read)whenI________(see)youatfouryesterdayafternoon?6、Whileshe__________(watch)TV,herson____________(play)outsidetheroom.7、It________(begin)torainwhilewe_____________(work)inthefield.8、I________(do)myhomeworklastnightwhenthelight_______(go)out.{goout意为熄灭}9、——Isawyouinthereadingroomyesterday,Tom.Whatwereyoudoing?------Oh,I____________(read)somebooksonscience.10.Girls___________(dance)whileboys____________(sing)attheparty.11.---DidyouseeTimjustnow?---Yes.He__________(fish)bytheriver.12.Whentheteacher______(come)intotheclassroom,thestudents__________(laugh)loudly.(一)、单选1What______fromthreetofouryesterdayafternoon?AhaveyoudoneBhadyoudoneCdidyoudoDwereyoudoing2–Icallyouyesterdayevening,buttherewasnoanswer.-Oh.,I’msorryI_____dinneratmyfriend’shome.AhomeBhadCwashavingDhavehad3Mymother_____whilemyfather_____TV.Acooked;waswatchingBwascooking;waswatchingCwascooked;watchedDcooked;watched4WhenIgothome,myson_____themusic.AamlisteningtoBlistenedtoCwaslisteningtoDwaslistening5Weheardacrywhenwe______TVlastnight.AwerewatchingBwouldwatchCwatchDwatched6Sheaskedhimwhetherhe_____backforlunch.AcomeBwascomingCcameDhadcome7Couldyoutellmewhen______?AsheiscomingBshewascomingCwillbecomeDishecoming8Theteacher______whenIcameintotheclassroom.AisdrawingBdrawsChasdrawnDwasdrawing9Thepizza______bymymother.Wouldyouliketohavesome?AmakesBwasmakingCmadeDwasmade10Nobodynoticedwhatshe______atthemoment.AwilldoBwasdoingChasdoneDhaddone11Wasitraininghardwhenyou_____thismorning?AleftBleavesCwasleavingDwouldleave参考答案:1D2C3B4C5A6B7A8D9D10B11A(二)、填空1______they______(feed)theanimalsat5:00yesterdayafternoon?2Mrs.Green__________(notwash)clothesatthistimeyesterday.3Grandpa____________(mend)hisclockwhenIreachedhome.4AsI_____(walk)inthepark,Isawsomechildrenplayinggames.参考答案:1werefeeding2wasn’twashing3wasmending4waswalking一)、单选1What______fromthreetofouryesterdayafternoon?AhaveyoudoneBhadyoudoneCdidyoudoDwereyoudoing2–Icallyouyesterdayevening,buttherewasnoanswer.-Oh.,I’msorryI_____dinneratmyfriend’shome.AhomeBhadCwashavingDhavehad3Mymother_____whilemyfather_____TV.Acooked;waswatchingBwascooking;waswatchingCwascooked;watchedDcooked;watched4WhenIgothome,myson_____themusic.AamlisteningtoBlistenedtoCwaslisteningtoDwaslistening5Weheardacrywhenwe______TVlastnight.AwerewatchingBwouldwatchCwatchDwatched6Sheaskedhimwhetherhe_____backforlunch.AcomeBwascomingCcameDha
