例题答案

Key:CDBBKey:CKey:CAKey:AKey:BBDAKey:DC

Key:AKey:BKey:DABKey:ABKey:CKey:A

Key:CKey:CC

练习答案与解析

1.B从第二个分句“他太矮了”可以推知说话者持否定态度,needn’t意思是“没有必要”,与语境不符。

2.C根据句意“我已经告诉她怎样到那儿,但是或许我应该给她写下来”可知,说话者含有“后悔、遗憾”的意味,应使用“情态动词+完成式”形式,“must+完成式”表示对过去的肯定推测,“should+完成式”才表示虚拟意义。

3.C根据第二分句“否则的话他就会给我打电话了”可知“Jack肯定还没到”,“can’t+完成式”意思是“根本不可能”。

4.A从第二分句可知,这是妇女和儿童专用候车室,因此你“不准”坐在这儿。mustn’t表示“禁止,不准”。

5.Bcan在此表示许可。

6.D从后一句“他喜欢开车”可知说话者把握不大。mustnot不表示推测,cannot的语气太绝对,意思是“根本不可能”。

7.Dshall用于第二、三人称,表示说话人给对方的命令、警告、允诺、威胁等意思。

8.Cshould在此表示惊讶的感情色彩,意思是“竟然”。

9.B对祈使句的肯定回答用Iwill;否定回答用Iwon’t。

10.D根据句意“我今天上午在会议室没见到她”,所以“她根本不可能在会上发言”。表示“根本不可能”用can’t/couldn’thavedone形式。

情态动词复习
1情态动词的语法特征
 1)情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。
 2)情态动词除ought和have外,后面只能接不带to的不定式。
 3)情态动词没有人称,数的变化,即情态动词第三人称单数不加-s。
 4)情态动词没有非谓语形式,即没有不定式,分词,等形式。
2比较can和beableto
1)can could表示能力;可能(过去时用could),
只用于现在式和过去式(could)。beableto可以用于各种时态。
 Theywillbeabletotellyouthenewssoon.他很快就能告诉你消息了。
2)只用beableto
 a.位于助动词后。
 b.情态动词后。
 c.表示过去某时刻动作时。
 d.用于句首表示条件。
 e.表示成功地做了某事时,只能用was/wereableto,不能用could。
 HewasabletofleeEuropebeforethewarbrokeout.
=HemanagedtofleeEuropebeforethewarbrokeout.
注意:could不表示时态
1)提出委婉的请求,(注意在回答中不可用could)。
---CouldIhavethetelevisionon?
---Yes,youcan./No,youcant.
2)在否定,疑问句中表示推测或怀疑。
Hecouldntbeabadman.
他不大可能是坏人。
3比较may和might
1)表示允许或请求;表示没有把握的推测;may放在句首,表示祝愿。
MayGodblessyou!
Hemightbeathome.
注意:might表示推测时,不表示时态。只是可能性比may小。
2)成语:may/mightaswell,后面接不带to的不定式,意为"不妨"。
 Ifthatisthecase,wemayaswelltry.
典型例题
 Peter___comewithustonight,butheisntverysureyet.
 A.mustB.may C.can D.will
 答案B.表可能性只能用may. 此句意可从后半句推出。
4比较haveto和must
1) 两词都是必须的意思,haveto表示客观的需要,must表示说话人主观上的看法,既主观上的必要。
Mybrotherwasveryill,soIhadtocallthedoctorinthemiddleofthenight. 我弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)
Hesaidthattheymustworkhard.他说他们必须努力工作。(主观上要做这件事)
2) haveto有人称、数、时态的变化,而must只有一种形式。但must可用于间接引语中表示过去的必要或义务。
Hehadtolookafterhissisteryesterday.
3)在否定结构中:donthaveto 表示"不必"
mustnt表示"禁止",
Youdonthavetotellhimaboutit. 你不一定要把此事告诉他。
Youmustnttellhimaboutit.你一定不要把这件事告诉他。
5must表示推测
 1)must用在肯定句中表示较有把握的推测,意为"一定"。
 2)must表对现在的状态或现在正发生的事情的推测时,must后面通常接系动词be的原形或行为动词的进行式。
 Youhaveworkedhardallday.Youmustbetired. 你辛苦干一整天,一定累了。(对现在情况的推测判断)
 Hemustbeworkinginhisoffice.他一定在办公室工作呢。
比较:
 Hemustbestayingthere. 
 他现在肯定呆在那里。
 Hemuststaythere.
 他必须呆在那。
 3)must表示对已发生的事情的推测时,must要接完成式。
Ididnthearthephone.Imusthavebeenasleep. 我刚才没有听到电话,我想必是睡着了。
 4)must表示对过去某时正发生的事情的推测,must后面要接不定式的完成进行式。
---Whydidntyouanswermyphonecall?
---Well,Imusthavebeensleeping,soIdidnthearit.
5)否定推测用cant。
IfTomdidntleavehereuntilfiveoclock,hecantbehomeyet. 如果汤姆五点才离开这儿,他此时一定还未到家。
6表示推测的用法
 can,could,may,might,must皆可表示推测,其用法如下:
1)情态动词+动词原形。
表示对现在或将来的情况的推测,此时动词通常为系动词。
Idontknowwheresheis,shemaybeinWuhan.
2)情态动词+动词现在进行时。
表示对现在或将来正在进行的情况进行推测。
Atthismoment,ourteachermustbecorrectingourexampapers.
这时,我们老师想必在批改试卷。
3)情态动词+动词完成时。
表示对过去情况的推测。
WewouldhavefinishedthisworkbytheendofnextDecember.
明年十二月底前我们很可能已完成这项工作了。
Theroadiswet.Itmusthaverainedlastnight.
地是湿的,昨天晚上一定下雨了。

4)情态动词+动词的现在完成进行时。
表示对过去正在发生事情的推测。
Yourmothermusthavebeenlookingforyou.
你妈妈一定一直在找你。
5)推测的否定形式,疑问形式用cant,couldnt表示。
Mikecanthavefoundhiscar,forhecametoworkbybusthismorning.
迈克一定还没有找回他的车,因为早上他是坐公共汽车来上班的。
注意:could,might表示推测时不表示时态,其推测的程度不如can,may。
7情态动词+have+过去分词
1)may(might)have+donesth,can(could)have+donesth 表示过去,推测过去时间里可能发生的事情。
Philipmay(might)havebeenhurtseriouslyinthecaraccident.
Philipcan(could)havebeenhurtseriouslyinthecaraccident.
2) musthave+donesth,对过去时间里可能发生的事情的推测,语气较强,具有"肯定","谅必"的意思。
 ---Lindahasgonetowork,butherbicycleisstillhere.
 ---Shemusthavegonebybus.
3)oughttohavedonesth,shouldhavedonesth
本应该做某事,而事实上并没有做。否定句表示"不该做某事而做了"。
Yououghtto(should)havebeenmorecarefulinthisexperiment.
Heoughtnottohavethrowntheoldclothesaway.(事实上已扔了。)
oughtto在语气上比should要强。
4)neednthavedonesth 本没必要做某事
Idressedverywarmlyforthetrip,butI neednthavedoneso.Theweatherwashot.
5)wouldliketohavedonesth 本打算做某事 
Iwouldliketohavereadthearticle,butIwasverybusythen.
8should和oughtto
should和oughtto都为"应该"的意思,可用于各种人称。
---Oughthetogo?
---Yes.Ithinkheoughtto.
表示要求,命令时,语气由should(应该)、hadbetter最好)、must(必须)渐强。
9hadbetter表示"最好"
hadbetter相当于一个助动词,它只有一种形式,它后面要跟动词原形。
hadbetterdosth
hadbetternotdosth
Itisprettycold.Youdbetterputonmycoat.
Shedbetternotplaywiththedog.
hadbetterhavedonesth表示与事实相反的结果,意为"本来最好"。
Youhadbetterhavecomeearlier.
10wouldrather表示"宁愿"
 wouldratherdo
 wouldrathernotdo
 wouldrather…than… 宁愿……而不愿。
还有wouldsooner,hadrather,hadsooner都表示"宁愿"、"宁可"的意思。
IfIhaveachoice,Ihadsoonernotcontinuemystudiesatthisschool.
 Iwouldratherstayherethangohome.=Iwouldstayhereratherthangohome.
典型例题
----Shallwegoskatingorstayathome?
----Which___do? 
A.doyouratherB.wouldyourather C.willyourather D.shouldyourather
答案B。本题考查情态动词rather的用法,wouldrather+dosth意为"宁愿",本题为疑问句,would提前,所以选B。

11will和would
 注意:
 1)wouldlike;Wouldliketodo=wantto想要,为固定搭配。
Wouldyouliketogowithme?
 2)Willyou…? Wouldyoulike…?表示肯定含义的请求劝说时,疑问句中一般用some,而不是any。
Wouldyoulikesomecake?
 3)否定结构中用will,一般不用would,wontyou是一种委婉语气。
Wontyousitdown?
12情态动词的回答方式
问句 肯定回答否定回答
Needyou…?Yes,Imust. No,Ineednt
Mustyou…? /donthaveto.
典型例题
1)---CouldIborrowyourdictionary?
---Yes,ofcourse,you____. 
 A.might B.will C.can D.should
 答案C.could表示委婉的语气,并不为时态。答语中ofcourse,表示肯定的语气,允许某人做某事时,用can和may来表达,不能用could或might。复习:will与you连用,用来提出要求或下命令。should与you连用,用来提出劝告。
2)---ShallItellJohnaboutit?
---No,you___.Ivetoldhimalready.
 A.needntB.wouldntC.mustntD.shouldnt
 答案A。neednt不必,不用。wouldnt将不,不会的。mustnt禁止、不能。shouldnt 不应该。本题为不需要,不必的意思,应用neednt。
3)---Dontforgettocometomybirthdaypartytomorrow.
---______.
A.Idont B. Iwont C.Icant D.Ihavent
答案B. will既可当作情态动词,表请求、建议、也可作为实义动词表"意愿、意志、决心",本题表示决心,选B。
13带to的情态动词
 带to的情态动词有四个:oughtto,haveto,usedto,beto,如加上havegotto,(=must),beableto,为六个。它们的疑问,否定形式应予以注意:
 Dotheyhavetopaytheirbillbeforetheendofthemonth?
 Shedidntusetoplaytennisbeforeshewasfourteen.
 Yououghtnottohavetoldherallaboutit.
 Oughthetoseeaheartspecialistatonce.?
oughtto本身作为情态动词使用。其他的词作为实义动词使用,变疑问,否定时,须有do
等助动词协助。

典型例题
 Tomoughtnotto___meyoursecret,buthemeantnoharm. 
 A.havetold B.tell C.betelling D.havingtold
 答案A。由于后句为过去时,告诉秘密的动作又发生在其前因,此地应用过去完成时,但它在情态动词oughtto后,所以用have。
14比较need和dare
 这两词既可做实义动词用,又可做情态动词用。作为情态动词,两者都只能用于疑问句,否定句和条件句。need作实义动词时后面的不定式必须带to,而dare作实义动词用时,后面的to时常可以被省略。
1)实义动词:need (需要,要求)
 need+n./todosth
2)情态动词:need,只用原形need后加do,否定形式为neednot。
Needyougoyet?
Yes,Imust./No,Ineednt.
3)need的被动含义:need,want,require,worth(形容词)后面接doing也可以表示被动: 
needdoing=needtobedone

高考英语备考情态动词


2011高考英语备考(考点聚焦+名题导解)情态动词一、考点聚焦1、情态动词的基本用法(1)can、beableto和could①can和beableto都表示能力,意思上没多大区别。但can只有现在和过去时,而beableto则有更多的形式。但当成功地完成某一具体动作时,通常不用could而用was/wereableto来表示。这时was/wereableto相当于managedto,表示经过一番努力,终于能够完成某事。如:Canyouusechopsticks?Thewoundedmanstillwasabletogettothevillageandwassavedintheend.②can和couldcan和could都可以表示能力、技能、许可、建议或请求和可能性。但比较委婉客气地提出问题或陈述看法,一般用could,回答时则用can。如:Couldyouhelpmecarrythebag?CanIhelpyou?(2)may/might①may/might表示可能,但may比might可能性大。如:-Whyisn’theinclass?

Hemaybesick.(生病的可能性较大)

Hemightbesick.(生病的可能性较小)

②may/might表示“允许”,may用于现在时或将来时,might常用在间接引语中表过去时,但might也可用于现在时间,表示比较委婉的语气,回答用may。如:

Hesayswemayleave.Hesaidwemightleave.③may/might表示建议或请求,但might比may更客气,意思更肯定而无过去时态的含义。Yes,youcan/may.—May/MightIuseyourbike?—No,youmustn’t(3)must①must表示必须,应该,没有时态变化。如:

YoumustdoeverythingasIdo.

②must表示肯定的推测。如:

Thelightisstillon,sohemustbeathome.

③mustn’t表示禁止做某事。如:

Youmustn’tsmokeintheoffice.

(4)haveto

haveto表示“必须、不得不”,是由于某种外界(客观)原因而“必须”,“不得不”做某事,也可表示经常的或习惯性的事“必须”做。haveto的否定形式表示不必。haveto可用于多种时态中。如:

Youwillhavetocleanyourownbootswhenyoujointhearmy.

Ihavetobeatmyofficeeveryevening.

(5)should/oughtto

①should和oughtto表示应当、应该,前者比后者语气轻。如:

Youshould/oughttoworkhard.

②should/oughttoworkhard.

Sincesheisnothere,wheshould/oughttobeintheclassroom.

③should/oughtto的否定形式表示禁止之意。如:

Childrenshouldn’tsmoke.

④should可表示陈述意见,推出建议或请求;而oughtto可以表示劝告之意。如:

Yououghttorespectyourparents.

Hesuggestedthattheyshouldleaveatonce.

(6)will/would

①will用于各种人称表示“意志”、“意愿”或“决心”等,否定式won’t+动词。如:

Iwilltellyouallaboutit.

Tomwon’tdosuchathing.

②will用于疑问句中,常用在第二称时表示说话人向对方提出“请求”或“询问”如:

Willyoupleasetellherthenewswhenyouseeher?

③will表示习惯性的动作,有“总是”、“惯于”的含义。如:

Fishwilldieoutofwater.

④would表示客气的请求、建议或意愿。如:

Wouldyoupleasebequiet?

Wouldyoulikecoffee?

⑤would表示过去反复发生的动作。如:

WhenIpassedmyschoolIwouldseemyteacherswhotaughtme5yearsago.

(7)need

need作“必要”讲,既可作情态动词,也可作实义动词。作实义动词时后面的动词不定式要带to,其变化与一般动词相同。如:

Ineedtothinkitover.

—Needyougonow?—Yes,Imust./No,Ineedn’t

(8)dare

dare表示“敢”的意思。作为情态动词时,主要用在疑问句和否定句中。dare若作实义动词,后面可带to的不定式,此时to也可以省略。dare与need的用法相似。如:

Howdareyousaythat?

Shedoesn’tdate(to)askherfather.

(9)usedto

usedto表示过去常常发生的动作或存在的习惯,但现在已不复存在了。如:

Heusedtosmoke.

(10)shall

①shall作为情态动词用于第二、三人称,表示说话人的意愿,有“命令”、“警告、威胁、强制”和“允许”等意思。如:

Weshalldoasourteachersays.

YoushallhavethebookassoonasIfinishit.

②在疑问句中,shall用于征求对方的意见或请求指示,常用于第一、第三人称。如:

Whereshallhewaitforus?

Shallwegooutforawalk?

2、情态动词表示推测或判断的用法

Shecan’tbeathome.=Itisimpossiblethatsheisathome.

Theyshouldbethererightnow.

3、情态动词在虚拟语气中的用法

情态动词用于虚拟语气中表示责备的感情色彩,用法如下:

(1)shouldhavedone表示“本来应该做某事而实际上未做”,而shouldn’thavedone则表示“本不应该做某事而实际上做了”。如:Youshouldhavetoldmeaboutitearlier.Youshouldn’thavesaidsuchwordstoyourparents.(2)oughttohavedone也表示“本应该……”而oughtnottohavedone则意为“本不应该……”。如:Yououghttohavetoldmeaboutitearlier.Yououghtnottohavesaidsuchwordstoyourparents.(3)needn’thavedone表示“本无必要做某事而实际上做了”。如:Youneedn’thavewalkedsoquicklysincetimewasenough.(4)couldhavedone表示“本来有可能……而事实上未做到”。如:Icouldhavecomeontime,butmycarbrokeontheway.ù二、精典名题导解选择填空1.Iwasreallyanxiousaboutyou.You________homewithoutaword.A.mustn’thaveB.shouldn’thaveleftC.couldn’thaveleftD.needn’thave解析:答案为B。本题考查的是情态动词在虚拟语气中的用法。题目给出的条件是“我确实非常担心你”,因此后面可知应是责备you不应该没说一句话就离开了。2.—AreyoucomingtoJeff’sparty?—I’mnotsure.I__________gototheconcertinstead.A.mustB.wouldC.shouldD.might解析:答案为D。本题考查情态动词的基本用法。由题目中“I’mnotsure”,表明我可能去Jeff’sparty,也可能去音乐会,故用might。3.—Willyoustayforlunch?—Sorry,____________.Mybrotheriscomingtoseeme.A.Imustn’tB.Ican’tC.Ineedn’tD.Iwon’t解析:答案为B。本题考查表示请求的英语口语,用will来向第二人称提问的疑问结构,是表示一种请求和意愿,是用疑问的形式来表达较为婉转的祈使语气,意思是“请你……,好吗”,对于这种问句的肯定回答是:Suree!Gertainly!Yes,ofcourse.I’dbegladto等;否定回答通常是:I’msorry,Ican’t.No,I’mafraidIcan’t.I’msorry,but…I’dliketo,but…等。注意情态动词表客气的用法及其在一般疑问句中的问与答。4.—Isn’tthatAnn’shusbandoverthere?—No,itbehimI’msurehedoesn’twearglasses.A.can’tB.mustnotC.won’tD.maynot解析:答案为A。本题考查情态动词表推测。问:那边的难道不是Ann的丈夫吗?答:不是。不可能是他,我确信他不戴眼镜。5.Youbetired-you’veonlybeenworkingforanhour.A.mustnotB.won’tC.can’tD.maynot解析:答案为C。本题考查情态动词。句中破折号后的内容对前一句进行解释说明:你只工作了一个小时,所以你不可能累的。表否定推测时用can’t。A项表禁止(不许),B项表未来,D项表不允许。均不可用,故选C。6.Ioftenseelightsinthatemptyhouse.DoyouthinkIreportittothepolice?A.shouldB.whateverC.whicheverD.whenever解析:答案为A。本题考情态动词。在空房子里看到灯光,是一件奇怪而令人生疑的事,故问:你是否认为我应当把这事儿报告给警察?应用A。
