Unit1What‘sthematter?

語法解析及訓練過去進行時一、過去進行時的含義、構成及句式

含義：過去進行時由“動詞was/were+v.-ing”構成，表示在過去某一時刻或某一時間段正在進行的動作。這一特定的過去時間除有上下文暗示以外，一般用時間狀語來表示，如:thistimeyesterday，alldayyesterday,allnight,atthattime,at9:30yesterday以及when/while從句等。例如:Hewasreadingabookathomealldayyesterday.昨天一整天他都在家里看書。Theywerehavingapartyat19:00yesterdayevening.昨天晚上7點他們在聚會。Hewasreadingastorybookwhentheteachercamein.老師進來的時候，他正在看故事書。基本構成及句式

肯定句：主語+was/were+doing+其他例如：TheboywasreadingwhenIsawhim.我看到那個男孩時，他正在看書。否定句:主語+wasn't/weren't+doing+其他例如：Hisfatherwasn'twatchingTVthistimeyesterday.昨天的這個時候他爸爸沒在家里看電視。一般疑問句：Was/were__+主語+doing____+其他?例如：WasthegirlshoppingwhenIsawher?例如：我看到那個女孩的時候她正在購物嗎？肯定回答：Yes,shewas.是的，她正在購物。其構成為：Yes,主語+was/were否定回答：No,shewasn‘t.不，她沒購物。其構成為：No,主語+wasn't/weren't特殊疑問句：特殊疑問詞+was/were+主語+動詞-ing形式+其他?例如：WhatwasthegirldoingwhenIsawher?我昨天看到那個女孩時，她正在干什么？可根據實際情況回答，Shewas+doing….?二、過去進行時的用法表示過去某一時刻正在發生的動作。常用時間狀語有atthistimeyesterday,atthattimeat,3o’clockyesterdayafternoon等。例如：Hewasswimmingatthistimeyesterday.昨天這個時候他正在泳泳。表示過去某一段時間內正在進行的動作。常用時間狀語:thismorning,thewholemorning/night,alldayyesterday,allnight等。例如：IwaswatchingTVthewholenight.整個晚上我都在看電視。表示過去某個動作發生。與when引導的時間狀語從句連用，另一個動作正在進行。例如：Iwasreadingwhentheteachercamein.老師進來時我正在讀書。與while引導的時間狀語從句連用，表示過去某兩個延續性動作同時進行。例如：Whilehewasreading,thetelephonerang.他正在看書時電話鈴響了。

Iwasplayinggameswhilemymotherwascooking.我打游戲的時候媽媽在做飯。與go,come,leave,start等瞬間動詞連用時，過去進行時表示過去即將發生的動作。例如：ShewasleavingforShanghaithen.那時候她就要動身去上海了。

Hesaidtheearlybuswascoming.他說早班車就要來了。與always,often、forever等頻度副詞連用時，表示對過去某件事的埋怨、滿意、稱贊、驚訝、討厭、贊揚或喜愛，并不強調動作正在進行，這一點與現在進行時相似。例如：Thebabywasalwayscrying.那個嬰兒總是哭。(表示抱怨)

Whywereyoualwaysgettinguplatelastweek?你上周怎么老是起床很晚?(表示埋怨)注意：部分動詞是不用于進行時的(1)感官動詞:hear，see,feel,taste...(2)表示愛憎的動詞:like，love,hate...(3)表希望、意愿的動詞:want,wish...(4)表占有的動詞:own，have...(5)其他動詞:appear,be...when,while和as引導的時間狀語從句都可以使用延續性動詞，when,as也可以與短暫性動詞連用，而while則不能。例如：Iwasdoingmyhomeworkwhenmymothergothomelastnight.昨晚當我媽媽回家時，我正在做作業。(gothome是短暫性動作)

TheycalledmewhenIwashavingdinner.當我正在吃晚飯時，他們給我打電話了。(washavingdinner是延續性動作)

Whilehewasridinghisbike，acarhithimsuddenly.當他正在騎自行車時，突然一輛小汽車撞了他。(wasriding是延續性動作)

AsIwaswalkingonedayinHydePark，Inoticedtwoelderlyladies.有一天，當我在海德公園散步的時候，我看到了兩位老年婦女。(waswalking是延續性動作)when可表示瞬間，也可表示時間段，表示從句與主句所陳述的動作、事情可以同時發生，也可有先后。若主句為過去進行時，從句為一般過去時，則表示一個動作正在進行的時候，另一個動作(突然)發生了，強調后一動作的突然性。例如：Iwasdoingmyhomeworkwhenmymothercamebackhomelastnight.昨晚當我媽媽回家時，我正在做作業。while用于同時進行的兩個延續性動作相伴隨而發生，常對同類的兩個動作進行比較。例如：MymotherwascookingwhilemyfatherwaswatchingTV.我媽媽正在做飯，(與此同時)我爸爸正在看電視。練習題一、選擇題1．—WhendidtheShiningShoppingMallhaveapowercut?—At9pmlastnight,whileI___afilmwithmybrotheratthecinema.A．haveseenB．wereseeingC．wasseeingD．saw2.I_____onthecomputerwhenFrankcalledmelastnight.A.WorkB.wasworkingC.willworkD.amworking答案：1.C2.B3．MyclassmatescheeredmeonloudlywhileI________atthesportsmeeting.A．runB．amrunningC．wasrunningD．willrun4.Whilethelights___tored,acarsuddenlyappearedaroundthecorner.A.ChangeB.havechangedC.werechangingD.willchange5．Lisa________toschoolwhenshesawtheaccidentyesterdaymorning.A.waswalkingB．iswalkingC.walkedD．haswalked6．___ImetKitty,she___forthebuswithherclassmateatthebusstop.A．When,waitedB．While,waswaitingC．While,waitedD．When,waswaiting答案：3.C4.C5.A6.C7.—DidTinaseeyougointothehouse?—Idon’tthinkso.She________herlittlecatthen.A．feedsB．wasfeedingC．fedD．isfeeding2.B8.Icalledyouyesterdayafternoon,butyoudidn'tpickup.Sorry.I___anonlineclassatthattime.A.TakeB.tookC.istakingD.wastaking9．—Lingling,whatwereyoudoingat7:00yesterdayevening?5.B—I________mymotherpreparethedinnerthen.A．helpsB．washelpingC．helpedDhelping10.TheGreens__TVtogetherfrom5:00to7:00yesterdayevening.A.iswatchingB.arewatchingC.waswatchingD.werewatching答案：7.B8.D9.B10.D11.Thewomanwithherdaughter_____inthatmallwhenshesawtheboyfalldown.A.ShoppedB.wasshoppingC.wereshoppingD.isshopping12.Mymother_____thedisheswhenIgothome.A.haswashedB.iswashingC.WashedD.waswashing13.MissLin__myLleiwithherlessonswhenIleftschool.-Sheisreallyaniceteacher.A.HelpsB.ishelpingC.washelpingD.helped14.I__withmyparentswhenherangmeupyesterdayafternoon.A.amshoppingB.amshopingC.wasshoppingD.wasshoping答案：11.B12.D13C1415.IsawKeninthemeetingroom;he____Joefortheschoolmagazine.A.InterviewsB.interviewedC.hasinterviewedD.wasinterviewing16.lcalledyouat8:00yesterdayevening,butnooneanswered.-Sorry.1__clothesformyparentsatthattime.A.WashB.washedC.amwashingD.waswashing17.Icalledyouthismorningbuttherewasnoanswer.—Oh,I________onlinecoursesathome.A．tookB.wastakingC．istakingD.willtake18.Iphonedyouthismorning.Buttherewasnoanswer.—Well.I________morningexercisethismorningA．wasdoingB．didC．amdoingD．woulddo答案：15.D16.D17.B18.A19．—Ann,Ididn’tseeyouatGina’spartyyesterdaymorning?—Oh,I____amuseumatthattime.A．amvisitingB．wasvisitingC．visitedD．willvisit20．Whydidn’tyouopenthedoorforme,Jim?I_____clothesinthebathroom.Ididn’theartheknock.A．amwashingB．washedC．waswashingD．wash21．—WhatdidMrs.Greensayjustnow?—Sorry,Ididn’tcatchit.I___withmyfriendsonline.A．waschattingB．amchattingC．Chatted.D.chats22．He________whenthepolicearrived.A.wascookingB.werecookingC.hascookedD.iscook答案：19.B20.C21.A22.A23．—Whydidn’tyouanswermycalllastnight?Iwantedtoborrowyournotebook.—Sorry.I________atthattime.A．sleepB．sleptC．issleepingD．wassleeping24．Amy________anonlinelessonwhenIcalledheryesterday.A．ishavingB．washavingC．hasD．had25．Whilemybrother________hiscomputer,myfathercamehomefromwork.A．repairedB．isrepairingC．wasrepairingD.repairs答案：23.D24.B25.C二、句型轉換，每空一詞。1.Thegirlwastalkingwithherclassmates.Hermothercalledher.(合并為一句)Thegirlwastalkingwithherclassmates_____hermothercalledher.2.Davidwaswritingareportattenyesterdaymorning.(改為否定句)David____writingareportattenyesterdaymorning.3.Thechildrenwerelaughingloudlyatthattime.(改為一般疑問句,并作肯定回答)_____thechildrenlaughingloudlyatthattime?_____,they_____。4.Wewerewaitingforthebusatthetimeoftherainstorm.(對畫線部分提問)
