外研版九年级(上)英语第8讲：Unit-4语法篇(学生版)

第8讲：Unit4语法篇____________________________________________________________________________________________________________________________________________________________________语法：情态动词的用法一、提建议。在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。(1).用“Let'sdo...”来提出建议。如：Let'sgoforawalkaftersupper.(2).用“What/Howabout...?”来提出建议；about后接名词或动词ing形式。如：Whatabout/Howaboutadrink?Whatabout/HowabouttakingTomwithus?(3).用“Whynot...?”来提出建议，表示“何不……”not面后接动词原形。“Whynot...?”实际上是“Whydon'tyou/we...?”的简略形式。如：Whynotmeetattheschoolgateateight?Whydon'twestayhereanotherday?(4).用“Wouldyoulike...?”来提出建议，意思是“你想要……吗?”Wouldyoulike后可接名词或不定式。如：Wouldyoulikeacupoftea?Wouldyouliketogoandseeher?因此，如果我们说：“去游泳好吗?”英语中可有这样几种表达法：Shallwegoforaswim?Let'sgoforaswim，shallwe?Whatabout/Howaboutgoingswimming?Whynotgoforaswim?Wouldyouliketogoforaswim?Whatdoyouthinkofgoingforaswim?二、语法：情态动词有can(could),may(might),must,haveto,shall(should,will(would),dare(dared),need(needed),oughtto等。情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语1.can,could1)表示能力（体力、知识、技能）。可用beableto代替。Can只有一般现在时和一般过去式；而beableto则有更多的时态。I’llnotbeabletocomethisafternoon.2)表示请求和允许。-----CanIgonow?-----Yes,youcan./No,youcan’t.3)表示客观可能性（客观原因形成的能力）。They’vechangedthetimetable,sowecangobybusinstead.Thishallcanhold500peopleatleast.4)表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。Canthisbetrue?2.may,might1)表示请求和允许。might比may语气更委婉，而不是过去式。否定回答时可用can’t或mustn’t，表示“不可以，禁止”。1.----Might/MayIsmokeinthisroom?----No,youmustn’t.2.----May/MightItakethisbookoutoftheroom?----Yes,youcan.(No,youcan’t/mustn’t.)2)表示推测、可能性（不用于疑问句）。might不是过去式，它所表示的可能性比may小。1．Hemay/mightbeverybusynow.2．Yourmothermay/mightnotknowthetruth.3.must,haveto1)表示必须、必要。Youmustcomeintime.在回答引出的问句时，如果是否定的，不能用mustn’t（禁止，不准），而用needn’t,don’thaveto（不必）.----Mustwehandinourexercisebookstoday?----Yes,youmust.----No,youdon’thaveto/youneedn’t.2)must是说话人的主观看法，而haveto则强调客观需要。Must只有一般现在时，haveto有更多的时态形式。Hisplayisn’tinteresting,Ireallymustgonow.IhadtoworkwhenIwasyourage.3)表示推测、可能性（只用于肯定的陈述句）1．You’reTom’sgoodfriend,soyoumustknowwhathelikesbest.Yourmothermustbewaitingforyounow.(2010.河北省卷,31.1)—Dowehavetofinishourhomeworkthisafternoon?—Yes,you________.A.must B.can C.may D.need2.（2010湖南省娄底市5.1）—MustIbeinhospitalforaweek，Doctor?
