情态动词小结及练习 情态动词专项训练及答案50题

        情态动词小结及练习情态动词有：can(could），may(might），must，haveto(hadto),shall(should），will(would，need,dare,oughtto等。一．情态动词can,may,must用法

        (一)基本用法1.can

        (1)会，能够--Canyouswim?--Yes,Ican.--No,Ican’t.

        (2)口语中代替may。Youcan(may)parkhere.你可以把车停在这里。

        (许可)2.may允许，许可--MayIcomein?--Yes,youmay./Sure,comeonin.--No,youmustn’t.No,youcan’t.(见练习16)No,you’dbetternot.3.must必须--Mustwefinishtheexercisetoday?--Yes,youmust.--No,youneedn’t.No,youdon’thaveto.4.need需要，必需--Needyougonow?=--Mustyougonow?--Yes,Imust.--Yes,Imust.--No,Ineedn’t.--No,Ineedn’t.(注：need作为情态动词，通常用在否定句和疑问句中)注意一：can与beableto都可以表示“能力”。区别是：

        （1）can只有现在和过去两种形式，即can和could。Icanplaythepiano.Shecouldn’tplaythepianowhenshewasalittlegirl.

        （2）beableto①有更多的形式和时态。

        Weshall/willbeabletofinishtheworknextweek.Ihaven’tbeenabletofindthebook.②指具体一次活动。IcanswimbutIamnotabletocrosstheroughsea.共同点是：当他们表示能力时，是同义的。Hecanspeaktwoforeignlanguages.=Heisabletospeaktwolanguages.I’mnotableto(can’t)answeryourquestion.Areyouableto(Canyou)type(打字)？注意二：could的用法

        （1）作为can的过去式，表示过去的能力。

        WhenIwasyoungIcouldclimbanytreeintheforest.这时也可用was(were)ableto

        （2）用来代替can，婉转地提出请求，想法，建议等。回答这种情况下could引导的一般疑问句时，不用could，而要用can。A:Couldyoutellmehowtogettothehospital?B:Ofcourse,Ican.注意三：must的否定形式表示“不得”，“一定不要”，“禁止”。

        ①Youmustn’ttakephotosinhere.It’sforbidden(禁止).②Youmustn’tdrivewithoutalicense（驾照）.③Wemustn’tbelate,mustwe？（与对比，此must不表猜测,两回事。）注意四：must的过去式是must，常用hadto代替。Ihadtoseethedentist.注意五：must和haveto都可以表示必须，但must表示说话人的主观看法，haveto表示客观需要。

        WemustloveChina.Youmustsaysorrytomeforthat.Youhavetodrivequickly,wehavelittletime.Ihaveto/mustdomyhomework.注意六：May+动词原形表“祝愿”。Mayyousucceed.Mayyoubehappyeveryday.(二）可能性用法1.can表示“可能性”①疑问句：只能用canWhocanitbe?那可能是谁？②否定句：cannot(can’t)“不可能”Itcan’t(cannot)beJenny.那不可能是珍妮。注意：在表示偶然性的可能性时，与sometimes连用，肯定句只能用can，意为“有时会”见专练48题。

        TheWorldWideWebissometimesjokingcalledtheWorldWideWaitbecauseit____beveryslowly.A.shouldB.mustC.willD.cankey：D“sometimes…can”意为“有时会”2.may表示“可能性”①肯定句：“大概”，“也许”，“可能”ItmaybeJenny.那可能是珍妮。②否定句：maynot“可能不”ItmaynotbeJenny.那可能不是珍妮。3.must表示“可能性”，只能用于肯定句，“准是”，“必是”，“必定”。

        ItmustbeJenny.那准是珍妮。小结表示“可能性”疑问句：只能用can否定句：cannot(can’t)“不可能”(反义词是must)maynot“可能不”肯定句：can“可能”(表示偶然性的可能性时，与sometimes连用，意为“有时会”)may“大概”；must“准是”(反义词是can’t)注意一：在表示“可能性”时，凡是对过去事物的猜测，不管是疑问句，否定句还是肯定句，都要用完成时，即“情态动词+动词的完成时”。①Itmusthaverainedlastnight.Yousee,thegroundisstillwet.②Hecan’thavebeentoyourhome.Hedoesn’tknowyouraddress.③I____havebeenmorethansixyearsoldwhentheaccidenthappened.A.shouldn’tB.couldn’tC.mustn’tD.needn’t④--Catherine,Ihavecleanedtheroomforyou.--Thanks.You____it.Icouldmanageitmyself.A.needn’tdoB.needn’thavedoneC.mustdoD.shouldn’thavedone⑤There____beanydifficultaboutpassingtheroadtestsinceyouhavepracticedalotinthedrivingschool.A.mustn’tB.shan’tC.shouldn’tD.needn’tkeys③Bcouldn’thavedone表示“不可能已经做了某事”④Bneedn’thavedone表示“过去不必做某事(本来不必可实际却做了)”而shouldn’thavedone表示“本来不该可实际却做了某事”见⑤题⑤Cshan’t=shallnot不表推测注意二：may+原型表示现在或将来的可能性。

        若表示对过去事物的猜测，则用完成时。①Hemaycometoday.(tomorrow)Hemightcometoday.(tomorrow)(might语气更不肯定，不是may的过去时)②Shemighthavecalledforhelp.她(当时)可能大声喊救命了。翻译句子：1.WherecanWeiFangbe?2.Thatcan’tbeMary.Sheisinhospital.3.Surelyyoucan’tbehungry.You’veonlyjusthadlunch.4.Youmay/cangoandaskhim.Buthemaynotansweryou.5.A:Look！Someoneiscoming.Whocanitbe?B:Itmaybeourheadmaster.A:Itcan’tbehim.HehasgonetoShanghai.B:ItmustbeMr.Zhang.Helookslikeourheadmaster.6.AnnamayknowTom’saddress.7.Theymaybewaitingatthestation.8.ImaybegoingtoEuropenextyear.9．Hemayhavegoneabroad.10.Youmustbehungry.Havesomethingtoeat.11.Theymustbetwins.12.There’salotnoisefromnextdoor.Theymustbehavingaparty.13.Ican’tfindhimanywhere.Hemusthaveleft.14.Ican’tfindmybook.Imusthaveleftitathome.15.Youmusthavebeenthinkingofsomething.16.A:WewenttoHainanforthewintervacation.B:Thatmusthavebeennice.注意三：must表示猜测时的反义疑问句

        （1）“mustbe+表语”的结构，must表示肯定猜测时，含有“准是”，“势必”，“一定”等意义时，反义疑问句用“isn’t/aren’t+主语”。

        Theymustbehungryafterthelongwalk,aren’tthey?

        （2）“musthavedone”表示猜测时，反义疑问句用“haven’t/hasn’t+主语”或“didn’t+主语”①TheymusthavestudiedEnglishbefore,haven’tthey?②Shemusthavemetafairy(仙女),hasn’tshe?③Youmusthaveseenthefilmlastweek,didn’tyou?解题秘笈：①把must去掉②找时间状语③重新组成一新句子④按新句子的时态造反义疑问句。①YoumusthavebeentoBeijing,＿＿＿＿＿？去掉must；无时状；重组成YouhavebeentoBeijing；故答案为：haveyou②Youmusthavefinishedyourhomeworkyesterday，＿＿＿＿＿？去掉must；时状为yesterday；重组成Youfinishedyourhomeworkyesterday；故答案为：didn’tyou二．情态动词need的用法

        （1）need表示“需要”，“必需”。作为情态动词，通常用在否定句和疑问句中。

        ①Heneedn’tpayforit.(情态动词)=Hedoesn’tneedtopayforit.(行为动词)②--Needyougonow?=--Mustyougonow?--Yes,Imust.--Yes,Imust.--No,Ineedn’t.--No,Ineedn’t.

        （2）need也可用作行为动词，其变化与一般动词相同。①Weneedtothinkitover.(肯定句)②Doesheneedtoknowit?=Needheknowit?③Shedidn’tneedtogo.=Sheneedn’tgo.

        （3）按句型背：needdoing=needtobedone①Thedoorneedspainting.=Thedoorneedstobepainted.②Theoldmanneededlookingafter.=Theoldmanneededtobelookedafter.三．情态动词dare的用法

        （1）dare表示“敢”作为情态动词，通常用于否定句，疑问句或条件句中。dare作为情态动词只有两种形式：dare,dared.①Shedarenotdoso.(否定句)②Darehedoit?(一般疑问句)③HowdareyousayI’munfair.(特殊疑问句)④Jumpifyoudare.（条件句）有胆量你就跳。

        (2)除了在“Idaresay…”这种习惯用语中，dare在肯定句中作情态动词的情况是很少的。（特殊用法，口语中常用，按句型背）①Idaresayyouarewrong.②A:Ifyoudie,whowillgetyourmoney？B:Idaresaymyunclewill.Ihavenootherrelatives(亲戚).

        （3）dare也可用作行为动词，其变化与一般动词相同。(注：当主语是③Wedidn’tdare(to)tryashot.四．情态动词shall和should的用法

        （1）shall作为情态动词，在陈述句中，用于二，三人称，表示说话人的意愿，有“命令”，“警告”，“威胁”，“强制”，“允诺”等意思。

        （在将来时中，原则上（言外之意：我明天一定会给他带来，表示说话人的意愿。）③Youshallhavewhateveryouwant.(诺言)√will（将来时）×(我答应)你要什么我给你什么。（证明不是将来时）④Heshallbesorryforitoneday.(警告)有一天他会后悔的，我告诉你。

        （2）在疑问句中，shall用来征询对方意见或请求指示，用于一，三人称。译成“（你说）…好吗？”。①WhereshallIwaitforyou?(你说)…②Shallhecomeatonce?(你说)他要不要立刻来?（征求你的意见，情态动词）区别：Willhecomeatonce？他将立刻来吗？（纯将来时）③Shallwestartthemeetingnow？(你说)…④Let’shavearest,shallwe?(Let’s包括对方)(你说)…对于上述这类问句的回答，没有严格不变的肯定或否定模式。

        ⑤ShallIopenthewindow?Yes,please.⑥ShallIgetyousomemoretea?Yes,please.⑦Shallwehaveameetingtomorrow?Yes,Iagree.Well,Idon’tthinkweneedto.⑧--Shallwegotherebybike?--Allright./OK./Yes,Ithinkso.)⑨--Shallwegotothepark?--Goodidea!
