一、过去将来时的概念表示从过去的时间看待将来要发生的动作或状态。即:过去将来时是“立足过去,着眼未来”的一种时态,常用于宾语从句中。判断这种时态的依据是:要有表示过去的“动作”,而不是时间。比较：一般将来时:表示从现在的时间看将来将要发生的动作或状态二、过去将来时的构成1、would/should+v2、was/weregoingto+v人称肯定句否定句一I/Weshould/woulddoI/Weshould/wouldnotdo二、三You/They/He/She/ItwoulddoYou/They/He/She/Itwouldnotdo疑问句疑问否定句Should/WouldI/wedo?Should/WouldI/wenotdo?Wouldyou/they/he/she/itdo?Wouldyou/they/he/she/itnotdo?人称一二、三缩写形式：肯定式：I’d,you’d,he’d,she’d,we’d,they’d,it’d否定式：I’d/you’d/he’d/she’d/we’d/they’d/it’dnot或I/you/he/she/we/they/itwouldn’t或I/weshouldn’t三、常连用的时间状语：thedayaftertomorrow→nextweek→tomorrow→tomorrowevening→thisafternoon→twodayslaterthenextweekthefollowingdaythenexteveningthatafternoon四、一般过去将来时的用法1.表示在过去某一时间看来将要发生的动作或存在的状态Lastweekhepromisedthathewouldcome,buthehasn’tarriveduntilnow.上周他答应来的，可直到现在还没到。Hesaidthathewouldwaitformeatthegate.他说他将在大门口等我。2.过去将来时常可用来表示过去习惯性的动作此时，不管什么人称，一律用would。Thisdoorwouldn'topen.这扇门老是打不开。Wheneverhehadtime，hewoulddosomereading.他一有时间，总是看书。IwouldplaywithhimwhenIwasachild.当我还是孩童时，总是和他一起玩。YouknowIwouldcome.你知道我会来的。3、come，go，leave，arrive，start等动词可用过去进行时代替过去将来时。例如：Hesaidthetrainwasleavingatsixthenextmorning.他说火车将于第二天早晨六点离开。Shetoldmeshewascomingtoseeme.她告诉我她要来看我。4、条件状语从句和时间状语从句中须用一般过去时代替过去将来时。例如：WhenshecameIwouldletyouknow.我不知道她什么时候来，但她来了我会告诉你。TheteachersaidthatitwouldbeverydifficulttomakeprogressifIdidn’tworkhard.老师说，如果我不努力学习的话，就很难取得进步。5、过去将来时，用于虚拟语气中IfIwereyou,Iwouldnotdothat.要是我是你的话，我就不会那样做。Ifhewerehere,hewouldshowushowtodoit.如果他在这儿，他就会向我们展示该如何做了。6、“was/wereaboutto+动词原形”,可以表示过去即将发生的事情。如:TheUSsaidthatthewaronIraqwasabouttostartinaweek.美国说伊拉克之战将在一周后打响。五、过去将来时典型错误例析1.我们不知道他是否要在会上发言。误：Wedidn’tknowwhetherheisgoingtospeakatthemeeting.正：Wedidn’tknowwhetherhewasgoingtospeakatthemeeting.析：该句主句为过去时，且宾语从句表示从过去某个时间看来将要发生的动作，所以从句要用过去将来时态。2.老师问汤姆长大后准备干什么。误：TheteacheraskedTomwhathewasgoingtobewhenhewouldgrowup.正：TheteacheraskedTomwhathewasgoingtobewhenhegrewup.析：在时间状语从句中，常用一般过去时表示在过去看来将要发生的动作。3.他们说如果下星期天不下雨他们就去农场。误：TheysaidthattheyweregoingtothefarmifitwouldnotrainthenextSunday.正：Theysaidthattheyweregoingtothefarmifitdidn’trainthenextSunday.析：在条件状语从句中，也常用一般过去时表示在过去看来将要发生的动作。4.王林打电话告诉她妈妈，她要买一些书误：WangLinranguptotellhermotherthatsheshouldbuysomebooks.正：WangLinranguptotellhermotherthatshewouldbuysomebooks.析：过去将来时可以由“助动词should/would+动词原形”构成，但should一般只用于第一人5.上次我见到你时，你正打算开始乘火车去西藏。误：LasttimeIsawyou，youhadstartedtogotoTibetbytrain.正：LasttimeIsawyou，youweregoingtostarttogotoTibetbytrain.析：,表示过去即将发生的事情用“was/wereaboutto+动词原形”结构。六、典题欣赏1.Shesaidshe_______ameetingthenextday.A.hadB.washavingC.willhaveD.wasgoingtohave2.Theyweresurethey______thefootballmatch.A.wonB.waswinningC.winD.wouldwin3.They_______afootballmatchwhenIsawthem.A.hadB.wouldhaveC.arehavingD.werehaving4.Weaskedhimwherehe_______thenextweek.A.wouldgoB.wentC.isgoingD.weregoing5.We______theScienceMuseumnextweek.A.wouldvisitB.willvisitC.isvisitingD.isgoingtovisit6.—Whatdidyoursonsayintheletter?—Hetoldmethathe______theDisneyWorldthenextday.A.willvisitB.hasvisitedC.isgoingtovisitD.wouldvisit7.IhopedTina______tomybirthdaypartyontimethenextWednesday.A.tocomeB.iscomingC.willcomeD.wascoming8.Fathersaidthathe______metoBeijingthenextyear.A.tookB.wouldtakeC.takesD.willtake9.Wewerenotsurewhetherthey______morevegetables.A.aregoingtogrowB.weregoingtogrowC.willgrowD.havegrown10.She______toworkwhenthetelephonerang.A.isgoingB.willgoC.wasgoingD.istogo
