Unit6单元语法和练习讲义外研版英语八年级上册

2025秋外研八上单元语法和配套练习Unit6过去进行时我们该如何表达“昨天晚上8点我在看电视”或“当时我在操场上打篮球”这样的意思呢？根据时间，我们可以判断这些是发生在过去的事情，是否可以用一般过去时来表达呢？首先，请看例句：Whatwereyoudoingat7amyesterday?7点你在做什么？Iwashavingbreakfast.我在吃早餐。一般来说，要表示过去某个时刻或某一时段正在进行的动作，我们常使用过去进行时。atthis/thattimeyesterdayat...lastnight等。过去进行时除了表示“过去某时刻/时段在做某事”之外，还常常出现在讲故事的语境中，请看下面的句子：Alicewassittingwithhersisterbytheriver.艾丽斯正和姐姐坐在河边。Theywerehavingateapartyinthegarden.他们正在花园里举行茶会。过去进行时句子中的谓语部分由“was/were+动词现在分词”构成，与现在进行时结构am/is/arewas/were。由此同学们可以推断，过去进行时的句式变化也与现在进行时的一样。请看下表：肯定否定一般疑问句及其回答特殊疑问句Iwasreadingabookatthattime.Iwasnot(wasn't)readingabookatthattime.Wereyoureadingabookatthattime?Yes,Iwas./No,Iwasnot(wasn't).Whatwereyoudoingatthattime?WewerehavingWewerenot—WereyouhavingapartyatWhatwereyou肯定否定一般疑问句及其回答特殊疑问句apartyatninelastnight.(weren't)havingapartyatninelastnight.ninelastnight?—Yes,wewere./No,wewerenot(weren't).doingatninelastnight?Youweresleepingthen.Youwerenot(weren't)sleepingthen.Wereyousleepingthen?Yes,Iwas/wewere./No,Iwasnot(wasn't)/wewerenot(weren't).Whatwereyoudoingthen?Shewassittingwithhersisterbytheriver.Shewasnot(wasn't)sittingwithhersisterbytheriver.Wasshesittingwithhersisterbytheriver?Yes,shewas./No,shewasnot(wasn't).Whatwasshedoingwithhersisterbytheriver?Theywereplayingbasketballat4pmyesterday.Theywerenot(weren't)playingbasketballat4pmyesterday.Weretheyplayingbasketballat4pmyesterday?Yes,theywere./No,theywerenot(weren't).Whatweretheydoingat4pmyesterday?那么，如何区别并准确使用过去进行时和一般过去时呢？试比较：Laurawasreadinganovelateighto'clocklastnight.8Laura在看小说。Laurareadanovellastnight.昨晚Laura看了一本小说。通过以上两个例句可以看出：这两种时态虽然都表示过去发生的事情，但是过去进行时强调过去某一时刻或时段正在进行或持续的动作；一般过去时表示过去的时间里所发生的动作，所表示的动作往往已经完成。通过前面的例句，我们知道过去进行时常和at...at...erdaymorning,atthattime,at...lastnightwhen,whileas引导的表示过去的时间状语从句连用，形成复合句。请看例句：Oneday,whenHenrywasworkinginarestaurant,asnakesuddenlyappeared.Henry正在餐馆里工作时，一条蛇突然钻了出来。Whilepeoplewerewaitingforthetrafficlights,acarsuddenlyappearedroundthecorner.就在人们等待红绿灯的时候，一辆汽车突然从拐角处驶出。Asthedoctorswerecheckinghim,thepaingotworse.二天，医生给他做检查时，疼痛加剧了。when和while引导的从句与过去进行时连用的几种情况。whenwhen词，也可以是延续性动词；而在while性动词。例如：Theyarrivedwhilewewerehavingdinner.我们吃饭的时候他们到了。这句话还可以写成：Theyarrivedwhenwewerehavingdinner.when表示一个动作正在进行的时候另一个动作(突然)发生了，强调后一动作发生的突然性。请看例句：Weweretalkingwhentheteachercamein.(突然)进来了。whilewhen表达有细微的区别，请注意体会：Whileweweretalking,theteachercamein.我们正在讲话的时候，老师进来了。(只表明老师进来的事实，不强调突然性)当主句和从句的动作都是延续的或同时发生的，两句都用过去进行时的时候，多while引导。例如：Theyweresingingwhileweweredancing.他们在唱歌，我们在跳舞。一、单项选择题—Whatwereyoudoingat9lastnight?—I abook.A.amreading B.wasreading C.willread readWhilemymother myfatherwaswatchingA.iscooking B.wascooking C.cooked cooksWhenI theroom,mysisterwaslisteningtomusic.A.entered B.wasentering C.enter amenteringThey footballat3pmyesterday.A.wereplaying B.played C.play areplaying—she thepianoatthattime?—Yes,shewas.A.play B.playing C.played toplayWewerewalkinginthepark itbegantorain.A.when B.while C.as for Iwasdoingmyhomework,mybrotherwasplayinggames.A.When B.While C.As ForThestudents aPEclasswhenitstartedtoA.werehaving B.had C.have arehavingWhilethey ameeting,someoneknockedattheA.werehaving B.had C.have arehaving—Whatweretheydoingwhilewe ?—Theyweresinging.A.dance B.danced C.weredancing aredancing二、用所给动词的正确形式填空I (watch)TVat8pmlastnight.Whilehe (read)abook,hismothercamein.They (play)basketballwhenitstartedtorain.WhenIgothome,myparents (cook)She (listen)tomusicatthattime.We (talk)whentheteacherenteredtheclassroom.Whilethey (swim),itbegantogetdark.Thechildren (sleep)whentheearthquakehappened.I (write)aletterwhilemysisterwasdoingthelaundry.Whenthephonerang,I (read)a三、句型转换Iwasreadingabookatthattime.（改为否定句）I abookatthattime.Theywereplayingfootballat4pm改为一般疑问句并作肯定回答）— they footballat4pmyesterday?—.Shewassittingwithhersisterbythe对划线部分提问） wasshe withhersisterbytheriver?Wewerehavingapartyatninelastnight.（改为反意疑问句）Wewerehavingapartyatninelastnight, ?Whilepeoplewerewaitingforthetrafficlights,acarsuddenlyappeared.（对划线部分提问） acarsuddenly ?四、翻译句子昨天晚上8点我正在做作业。当她正在打电话时，门铃响了。我们正在散步的时候，天下起了雨。他们当时正在看电视。当我正在跑步时，我看到了我的朋友。五、短文填空阅读下面短文，用括号内所给动词的正确形式填空。LastSunday,I1(go)totheparkwithmyfamily.Whenwe2(arrive),manypeople3(play)badmintononthegrass.Myparents4(sit)onabenchand5(talk).Mylittlebrother6(run)aroundhappily.I7(fly)akite.WhileI8(fly)thekite,ImetmyclassmateTom.He9(be)alsointheparkwithhisfamily.We10(start)toplaytogether.Wehadagreattimethatday.配套练习答案一、单项选择题110BBAABABAAC二、用所给动词的正确形式填空1.waswatching 2.was3.wereg 3.wereplaying 4.werecooking 5.waslistening6.weretalking 7.wereswimming 8.weresleeping 9.waswriting 10.was三、句型转换reading 2.Were;playing;theywere 3.What;doing 5.Whendid;appear四、翻译句子Iwasdoingmyhomeworkat8pmlastni
