must表示说话人对事物的推测可能性的程度非常大，意为“一定；准是”；表示有把握的否定推测时用can’t，意为“不可能”。如：1.Ican’tfindmykeys.Imusthaveleftthemathome.2.--IssheMary?--Thatcan’tbeher.She’sinhospital.

can表示“可能”，常用于否定句、疑问句中。could为can的过去式，表示推测的语气较can弱。如：--Canthemantherebeourmathteacher?--Hemaybe,butIamnotsure.

may意为“也许”。might为may的过去式，表示说话人对现在或将来不太确定的可能性的推测。如：LiMingmightgethereintime,butIamnotsure.意思推测程度must一定，肯定100%的可能性maymight/could有可能，也许20%---80%的可能性can’t不可能，不会可能性几乎为零1.Ididn’thearthephone.I___asleep.A.mustbeB.musthavebeenC.shouldbeD.shouldhavebeen2.Mary____beinParis.Isawherintownonlyafewminutesago.A.mustn’tB.shouldn’tC.can’tD.maynotChoosethebestanswer.【浙江湖州】—Who’ssinginginthenextroom?—It____beher.ShehasgonetoNewYork.A.can’tB.mustC.shouldn’tD.can【解析】考查情态动词表推测。表示否定推测时，用can’t，意为“一定不……”。must表示推测时，意为“一定……”，用于肯定句；根据答语“她已经去了纽约”可知是否定推测，故选A。中考链接【2011湖北黄冈】41.—WhoseT-shirtisthis?—It___beJohn's.It’s___smallforhim.A.can't;muchtooB.can't;toomuchC.mustn't;muchtooD.mustn't;toomuch【解析】情态动词的用法。根据句意“它不可能是约翰的，对他来说太小了。”故排除C、D，toomuch为“太多”的意思，muchtoo为“太”。故选A。【2013天津】—Whereareyougoingthismonth?—We______gotoXiamen,butwe'renotsure.A.needn’tB.mustC.mightD.mustn't【解析】needn’t(不必)表建议；must(一定)表猜测的可能性很大；might(可能，也许)表不是很肯定的猜测。mustn't(不允许)表命令。句意：---这个月你们将去哪？---我们或许去厦门，但还不确定。C【2013福建泉州】---Haveyoudecidedwheretogoforyoursummervacation?---Notyet.We_______gotoQingdao.It'sagoodplaceforvacation.A.mayB.needC.must【解析】句意：---你已经决定到哪里过暑假了吗？---还没有呢，我们也许去青岛，那是个度假的好地方。情态动词表示推测时，may表“可能”，must表“一定”，can’t表“不可能”。A【2014铜仁】—MustIwatertheflowersnow,mum?—No,you______.You_____doitlater.A.mustn’t;mustB.mustn’t;mayC.needn’t;mayD.needn’t;must【2014连云港】—______Iknowbywhattimeyouwanttheprojecttobedone?—Bythedayaftertomorrow.______youfinishitontime?A.May;Can B.Must;Need C.Could;Must D.Need;WouldCA【2014长沙】—Who’ssinginginthegarden?—It______beMr.Brown.Healwayspracticessingingatthistime.A.must B.can’t C.need【2014河北】I______followyou.Wouldyoupleaserepeatit?A.can’t B.mustn’tC.needn’t D.shouldn’tAA1.A:Where’sJean?B:I’mnotsure.She_________(is/mightbe/mustbe)inthelaboratory.2.A:Everyoneisgoingtothepoolafterschool.B:Really?It_________(mustbe/can’tbe/couldbe)hotoutdoors.4amightbemustbe3.A:That’sthephone.B:Hmm.Iwonderwhoit________(mustbe/couldbe/shouldbe).4.A:IwonderiftheseareJim’sglasses.B:They________(can’tbe/mightbe/couldbe)his.Hedoesn’twearglasses.5.A:Ihearwaterrunninginthebathroom.B:It_________(couldbe/mustbe/can’tbe)Carla.Shewasthinkingoftakingashower.couldbecan’tbemustbeCompletetheseresponses1.A:Manypeoplearewearingcoats.B:Theweathermustbe________.2.A:Sallyhasbeencoughingalot.B:Shemightbe_______.A:Thisrestaurantisalwayscrowed.B:Thefood_______________.A:WheneverItrytoreadthisbook,Ifeelsleepy.B:Itcan’t________________.4bbeinterestingcoldillmustbedeliciousLookatthispictureofaroom.Howmuchcanyoutellaboutthepersonwholiveshere?Isitaboyoragirl?Whatarehis/herhobbies?Discussyourideaswithapartner.A:Itcouldbeagirl’sroombecauseit’sverytidy.B:Iguessso.Butitmightbeaboy’sroombecausetheclotheslooklikeboys’clothes.4c1.—Excuseme.IsthistherightwaytotheSummerPalace?
