外研版九年級(jí)(上)英語(yǔ)第8講：Unit-4語(yǔ)法篇(教師版)

第8講：Unit4語(yǔ)法篇____________________________________________________________________________________________________________________________________________________________________語(yǔ)法：情態(tài)動(dòng)詞的用法一、提建議。在英語(yǔ)中，我們可以用其他多種方式提出我們的建議或征求對(duì)方意見(jiàn)。(1).用“Let'sdo...”來(lái)提出建議。如：Let'sgoforawalkaftersupper.(2).用“What/Howabout...?”來(lái)提出建議；about后接名詞或動(dòng)詞ing形式。如：Whatabout/Howaboutadrink?Whatabout/HowabouttakingTomwithus?(3).用“Whynot...?”來(lái)提出建議，表示“何不……”not面后接動(dòng)詞原形。“Whynot...?”實(shí)際上是“Whydon'tyou/we...?”的簡(jiǎn)略形式。如：Whynotmeetattheschoolgateateight?Whydon'twestayhereanotherday?(4).用“Wouldyoulike...?”來(lái)提出建議，意思是“你想要……嗎?”Wouldyoulike后可接名詞或不定式。如：Wouldyoulikeacupoftea?Wouldyouliketogoandseeher?因此，如果我們說(shuō)：“去游泳好嗎?”英語(yǔ)中可有這樣幾種表達(dá)法：Shallwegoforaswim?Let'sgoforaswim，shallwe?Whatabout/Howaboutgoingswimming?Whynotgoforaswim?Wouldyouliketogoforaswim?Whatdoyouthinkofgoingforaswim?二、語(yǔ)法：情態(tài)動(dòng)詞有can(could),may(might),must,haveto,shall(should,will(would),dare(dared),need(needed),oughtto等。情態(tài)動(dòng)詞無(wú)人稱和數(shù)的變化；不能單獨(dú)使用，必須與其后的動(dòng)詞原形構(gòu)成謂語(yǔ)1.can,could1)表示能力（體力、知識(shí)、技能）?？捎胋eableto代替。Can只有一般現(xiàn)在時(shí)和一般過(guò)去式；而beableto則有更多的時(shí)態(tài)。I’llnotbeabletocomethisafternoon.2)表示請(qǐng)求和允許。-----CanIgonow?-----Yes,youcan./No,youcan’t.3)表示客觀可能性（客觀原因形成的能力）。They’vechangedthetimetable,sowecangobybusinstead.Thishallcanhold500peopleatleast.4)表示推測(cè)（驚訝、懷疑、不相信的態(tài)度），用于疑問(wèn)句、否定句和感嘆句中。Canthisbetrue?2.may,might1)表示請(qǐng)求和允許。might比may語(yǔ)氣更委婉，而不是過(guò)去式。否定回答時(shí)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)表示推測(cè)、可能性（不用于疑問(wèn)句）。might不是過(guò)去式，它所表示的可能性比may小。1．Hemay/mightbeverybusynow.2．Yourmothermay/mightnotknowthetruth.3.must,haveto1)表示必須、必要。Youmustcomeintime.在回答引出的問(wèn)句時(shí)，如果是否定的，不能用mustn’t（禁止，不準(zhǔn)），而用needn’t,don’thaveto（不必）.----Mustwehandinourexercisebookstoday?----Yes,youmust.----No,youdon’thaveto/youneedn’t.2)must是說(shuō)話人的主觀看法，而haveto則強(qiáng)調(diào)客觀需要。Must只有一般現(xiàn)在時(shí)，haveto有更多的時(shí)態(tài)形式。Hisplayisn’tinteresting,Ireallymustgonow.IhadtoworkwhenIwasyourage.3)表示推測(cè)、可能性（只用于肯定的陳述句）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湖南省婁底市5.1）—MustIbeinhospitalforaweek，Doctor?
