語法專題八、情態動詞（常考）考點考點精講情態動詞表示講話人的態度、請求、許可、愿望、可能等。本身具有一定的意義，但不能獨立作謂語，沒有人稱和數的變化，且后面必須跟動詞原形。常考的情態動詞有：can/could（能夠，可以），may/might（可能，可以），must（必須，一定），should（應該），need（必要），haveto（不得不）等。Need用作情態動詞時常用于否定句和疑問句，need還可作實意動詞，常用結構needtodosth.考點1.情態動詞+動原Hecanplaytheviolin.他會拉小提琴。Itmightsnowtomorrow.明天可能下雪。Weshouldrespecteveryone.我們應該尊重每一個人。考點2.常考的一般疑問句的回答—Canyouswim?—Yes,Ican./No,Ican’t.—MayIsmokehere？—Yes,youmay/can./Sure./Certainly./Ofcourse./No,youmustn't/can’t.—Mustwefinishtheworkatonce？—Yes，youmust./No，youneedn't./No，youdon'thaveto.（must引導的一般疑問句的否定回答是常考點）考點3.must必須（強調主觀看法）mustn’t表示禁止，不允許Youmuststudyharderthisterm.你們這學期必須更加努力學習。（說話者的個人看法）Youmustn’tswimintheriver.你們千萬不能去河里游泳。（這條河禁止游泳）考點4.情態動詞表推測表推測：由強到弱肯定：must準是，一定can可能could（可能）may(或許)might（大概）否定：can’t不可能may/mightnot或許不能can和could表示推測，can表示推測時，往往用于否定句和疑問句。用于疑問句時，can比could表示的“可能性”要大；用于否定句時，cannot（can't）表示“不可能”。could則可用于肯定句、否定句和疑問句。情態動詞表推測常考的三點：十分肯定的推測，肯定句，用must.（一定是）ThisbookmustbeTom’s.There’shisname.這本書一定是湯姆的，有他名字。斷然否定的推測，否定句，用can’t（一定不是）—Listen,thereissomebodyknockingonthedoor?IsitMsGao?聽，有人敲門？是高老師嗎？—No,itcan’tbeMsGao.Ijustsawherrunningontheplayground.不，不可能是高老師。我剛才看見她在操場是跑步呢。3.不太確定，沒把握，肯定句，用may/might（可能）—Listen,whoisknockingonthedoor?聽，誰在敲門？ItmightbeMsZhao.I’mnotsure.可能是趙老師。我不確定。1.(2014·江蘇省揚州市·歷年真題)-Excuseme，mayIkeepthebookalittlelonger？-Sorry．You________returnittoday．A.must B.mustn't C.can D.can't2.(2014·天津市·歷年真題)Lookatthe"Noparking"sign.You______parkyourcarhere.A.should B.must C.needn't D.mustn't3.(2022·天津市·歷年真題)—____Ifinishthewritingnow？—No，you______.YoucangiveittomenextMonday.A.Must；mustn't B.Must；needn't C.May；shouldn't D.Need；can't4.(2022·全國·歷年真題)—IsthatmanMr.Green?
