第一单元一定语从句:定语从句的介绍就像是一个形容词或介词短语修饰名词一样,定语从句也可以修饰名词。定语从句所修饰的名词称为先行词。形容词:Thegreenteam介词短语:Theteamingreen定语从句:Theteamwhowerewearinggreen定语从句通常由关系代词来引导,如which,that,who,whom,whose,或关系副词来引导,如when,where,why。关系代词可以在定语从句中担当主语,宾语,表语,定语;关系副词可以在定语从句中担当状语。如:做主语Thetreeswhichareontheschoolcampushavelosttheirleaves.做宾语Thestudentwhomwesawjustnowisthebestrunnerinourschool.做表语Jackisnolongerthelazyboythatheusedtobe.做定语ShehasabrotherwhosenameIcan’tremember.做状语TheschoolwherehestudiedisinShenzhen.二定语从句:关系代词:that,which,who,whom,和whose在定语从句中,that和which用来指代物。eg:Thisisthestorythat/whichwewroteforourstorytellingcontest.在定语从句中,who用来指代人。eg:IamgoingtoseeafriendwhohasjustcomebackfromtheUK.当who在定语从句中做宾语时,可以用whom来取代,且whom比who更正式。eg:Idon’tknowthenameoftheteacherwho/whomIsawinthecomputerroomtheotherday.当关系代词在定语从句中做宾语时,who,whom,which和that可以被省略。eg:Helikesallthebirthdaypresents(that/which)hisfriendsgavehim.Whose用来表示所属,它既可指人也可指物。eg:IsatnexttoagirlwhosenamewasDiane.TheclubwhosemembersaremusicfansmeetintheschoolgardeneverySaturdayafternoon.第二单元一定语从句:介词提前的定语从句(preposition+which;preposition+whom)当关系代词(which/whom)做定语从句中介词的宾语时,可以把介词提到关系代词的前面。eg:Wethoughtyouwereapersonfromwhomwecouldexpectgooddecisions.在非正式英语中,介词通常放在定语从句的最后。eg:ArtisthesubjectwhichIknowlittleabout.如果介词放在定语从句的最后,which可以被that取代,whom可以被that和who取代。eg:Dadisapersonwhom/that/whoIcaneasilytalkto.当关系代词做定语从句中介词的宾语,并且介词又放在定语从句的末尾时,我们通常省略关系代词who和that。eg:Thetopic(which)EricisinterestedinisPhysics.Danielistheperson(whom)Iwanttomakefriendswith.当先行词是way时,我们用inwhich或that来引导定语从句,这种情况下,inwhich或that可以被省略。eg:Ididn’tliketheway(that/inwhich)shetalkedtome.二定语从句:关系副词:when,where,why1.我们通常用关系副词when引导先行词是time,moment,day,season,year等的定语从句。eg:Doyourememberthedaywhenweleftyouincharge?IoftenthinkofthemomentwhenIsawtheUFO.2.我们通常用关系副词where引导先行词是place,house,city,country,city,world等的定语从句。eg:Thepolicesearchedthehousewherethethiefhadstayed.Thisisnotafamilywherebadbehaviorgoesunpunished.3.我们通常用关系副词why引导先行词是reason的定语从句。eg:Idon’tknowthereasonwhythehouseissodirty.4.在更加正式的英语中,where,when和why能够被介词+which所替代。eg:Thestudyistheplacewhere/inwhichIoftenhavetalkswithmyfather.Thisisthereasonwhy/forwhichmyparentsgothomeearlier.Itrainedthewholedaywhen/onwhichhetraveledwithhisfamily.第三单元一定语从句:非限制性定语从句1.非限制性定语从句是一个为主句添加额外信息的从句,在非限制性定语从句前通常有个逗号。eg:Amy,whotookweight-losspills,nowrealizesthathealthisimportant.Mypillsareinthebathroom,whereIalwayskeepthem.2.当先行词是整个主句时,可以用which来引导定语从句。eg:Hemissedtheshow,whichwasagreatpity.3.我们可以用all+whom/which来表示全部数量,用someof+whom/which来表示部分数量。eg:Iamdoingdifferenttypesofexercises,allofwhicharequitehelpfultomyhealth.Manypeople,someofwhomarenotoverweight,aregoingondiet.定语从句练习1.Isthisthefactory__________youvisitedtheotherday?A.thatB.whereC.inwhichD.theone2.Isthisfactory__________someforeignfriendsvisitedlastFriday?A.thatB.whereC.whichD.theone3.Isthisthefactory__________heworkedtenyearsago?A.thatB.whereC.whichD.theone4.Thewolveshidthemselvesintheplaces__________couldn’tbefound.A.thatB.whereC.inwhichD.inthat5.Thefreezingpointisthetemperature__________waterchangesintoice.A.atwhichB.onthatC.inwhichD.ofwhat6.Thereasonis__________heisunabletooperatethemachine.A.becauseB.whyC.thatD.whether7.I’lltellyou__________hetoldmelastweek.A.allwhichB.thatC.allthatD.which8.Thattree,__________branchesarealmostbare,isveryold.A.whoseB.ofwhichC.inwhichD.onwhich9.Ihaveboughtthesamedress__________sheiswearing.A.asB.thatC.whichD.what10.We’retalkingaboutthepianoandthepianist_________wereintheconcertweattendedlastnight.A.whichB.whomC.whoD.that11.Anyone__________thisopinionmayspeakout.A.thatagainstsB.thatagainstC.whoisagainstD.whoareagainst12.Didn’tyouseetheman__________?InoddedjustnowB.whomInoddedjustnowC.InoddedtohimjustnowD.Inoddedtojustnow13.Isthereanything__________toyou?A.thatisbelongedB.thatbelongsC.thatbelongD.whichbelongs14.----“Howdoyoulikethebook?”----“It’squitedifferentfrom__________Ireadlastmonth.”A.thatB.whichC.theoneD.theonewhat15.Mr.Zhanggavethetextbooktoallthepupilsexcept__________whohadalreadytakenthem.A.theonesB.onesC.someD.theothers16.Thetrain__________shewastravellingwaslate.A.whichB.whereC.onwhichD.inthat17.It’sthethirdtime__________latethismonth.A.thatyouarrivedB.whenyouarrivedC.thatyou’vearrivedD.whenyou’vearrived18.Maythefourthistheday__________weChinesepeoplewillneverforget.A.whichB.whenC.onwhichD.aboutwhich19.Isitinthatfactory__________“RedFlag”carsareproduced?A.inwhichB.whereC.whichD.that20.HemustbefromAfrica,__________canbeseenfromhisskin.A.thatB.asC.whoD.what21.Hehastwosons,__________workaschemists.A.twoofwhomB.bothofwhomC.bothofwhichD.allofwhom22.I,__________yourgoodfriend,willtrymybesttohelpyouout.A.whoisB.whoamC.thatisD.whatis23.Idon’tlike__________youspeaktoher.A.thewayB.thewayinthatC.thewaywhichD.thewayofwhich24.Thetwothings______theyfeltveryproudareJim’sgoldwatchandDella’shair.A.aboutwhichB.ofwhichC.inwhichD.forwhich25.Doyouknowwhichhotel__________?A.sheisstayingB.sheisstayinginC.isshestayingD.isshestayingin26.Whocanthinkofasituation__________thisidiomcanbeused?A.whichB.thatC.whereD.inthat27.Theastronautdidmanyexper

从句中担任成分,如主语、表语、宾语、或定语等。2、连接副词:when,where,why,how。有词义,在从句中担任成分,作状语。3、连接词:that,whether,if,asif。that无词义,在从句中不担任成分,有时可省略;if(whether),asif虽有词义,但在从句中不担任成分。注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether和if(是否),asif(好象)在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if和asif都用不上时,才用that作连接词(that本身无任何含义)。(二)主语从句1、主语从句在复合句作主语。e.g.Whowillgoisnotimportant.2、用it作形式主语,主语从句放在句末。e.g.Itdoesn’tmattersomuchwhetheryouwillcomeornot.3、that引导主语从句时,不能省略。e.g.Thathesuddenlyfellilllastweekmadeussurprised.(三)表语从句1、表语从句在复合句中作表语,位于系动词之后。e.g.Thequestionwaswhocouldgothere.2、引导表语从句的连接词that有时可省去。e.g.Myideais(that)wecangetmorecomradestohelpinthework.(四)宾语从句1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。e.g.Ihope(that)everythingisallright.2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。e.g.I’minterestedinwhetheryou’vefinishedthework..I’minterestedinwhatyou’vesaid.3、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。①宾语从句是否定句时,只用if,不用whether。e.g.Iwonderifitdoesn’train.②用if会引起误解,就要用whether。e.g.Pleaseletmeknowwhetheryouwanttogo.(此句如果把whether改成if,容易当成条件句理解)③宾语从句中的whether与ornot直接连用,就不能换成if;不直接连用,可换。e.g.Idon’tknowwhetherornotthereportistrue.Idon’tknowwhether/ifthereportistrueornot.④介词后的宾语从句要用whether引导。whether可与不定式连用。whether也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if。但引导条件从句时,只能用if,而不能用whether。e.g.Itdependsonwhetherwehaveenoughtime.Theydon’tknowwhethertogothere.Pleasecometoseemeifyouhavetime.(五)同位语从句同位语从句在句中作某一名词的同位语,一般位于该名词(如:news,fact,idea,suggestion,promise等)之后,说明该名词的具体内容。e.g.Ihavenoideawhenhewillbeback.Thefactthathehadnotsaidanythingsurprisedeverybody.练习:1.Thefact____sheworkshardiswellknowntousall.A.thatB.whatC.whyD.which2.Thefact____hewassuccessfulproveshisability.A.thatB.whatC.whichD.why3.Thenews____hewaskidnappedsurprisedusgreatly.A.whatB.thatC.whyD.when4.Hissuggestion____themeetingbedelayedwasturneddown.A.whichB.thatC./D.it5.Ihavenoidea____hewillstart.A.whenB.thatC.whatD./6.I'vecomefromthegovernmentwithamessage____themeetingwon'tbeheldtomorrow.A.ifB.thatC.whetherD.which7.Thethought____hemightfailintheexamworriedhim.A.whenB.whichC.whatD.that8.Theorder____theprisonerbesetfreearrivedtoolate.A.whichB.whetherC.thatD.what9.Thenursesaretryingtheirbesttoreducethepatient'sfear____hewoulddieofthedisease.A.thatB.asC.ofwhichD.which10.Heoftenaskedmethequestion____theworkwasworthdoing.A.whetherB.whereC.thatD.when11.Alongwiththeletterwashispromise____hewouldvisitmethiscomingChristmas.A.whichB.thatC.whatD.whether12.Theotherday,mybrotherdrovehiscardownthestreetat____Ithoughtwasadangerousspeed.A.asB.whichC.whatD.that13.Luckily,we’dbroughtaroadmapwithout____wewouldhavelostourway.A.itB.thatC.thisD.which14.Therearesigns____restaurantsarebecomingmorepopularwithfamilies.A.thatB.whichC.inwhichD.whose15.Wecanseethesamesigns____standoutthroughoutthecity.A.thatB.whichC.inwhichD.whose主谓一致在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致。寻其规律,大致可归纳为三个原则,即语法一致、逻辑意义一致和就近一致原则。(一)语法一致原则:语法上一致就是谓语动词和主语在单、复数形式上保持一致。1、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时,谓语动词一般用单数形式;主语为复数时,谓语动词用复数形式。如:Hisfatherisworkingonthefarm./TostudyEnglishwellisnoteasy./Whathesaidisveryimportantforusall./Thechildrenwereintheclassroomtwohoursago./Readinginthesunisbadforyoureyes.注意:由what引导的主语从句,后面的谓语动词多数情况用单数形式,但若表语是复数或what从句是一个带有复数意义的并列结构时,主句的谓语动词用复数形式。如:WhatIboughtwerethreeEnglishbooks./WhatIsayanddois(are)helpfultoyou.2、由连接词and或both…and连接起来的合成主语后面,要用复数形式的谓语动词。如:LucyandLilyaretwins./SheandIareclassmates./Theboyandthegirlweresurprisedwhentheyheardthenews./BothsheandheareYoungPioneers.注意:①若and所连接的两个词是指同一个人或物时,它后面的谓语动词就应用单数形式。如:Thewriterandartisthascome.;/②由and连接的并列单数主语前如果分别有no,each,everymorethana(an),manya(an)修饰时,其谓语动词要用单数形式。如:Everystudentandeveryteacherwasintheroom../Noboyandnogirllikesit.3、主语为单数名词或代词,尽管后面跟有with,togetherwith,except,but,like,aswellas,ratherthan,morethan,nolessthan,besides,including等引起的短语,谓语动词仍用单数形式;若主语为复数,谓语用复数形式。如:MrGreen,togetherwithhiswifeandchildren,hascometoChina./NobodybutJimandMikewasontheplayground./She,likeyouandTom,isverytall.4、either,neither,each,every或no+单数名词和由some,any,no,every构成的复合不定代词,都作单数看待。如:Eachofushasanewbook./Everythingaroundusismatter.注意:①在口语中当either或neither后跟有“of+复数名词(或代词)”作主语时,其谓语动词也可用复数。如:Neitherofthetextsis(are)interesting.②若noneof后面的名词是不可数名词,它的谓语动词就要用单数;若它后面的名词是复数,它的谓语动词用单数或复数都可以。如:Noneofushas(have)beentoAmerica.5、在定语从句时,关系代词that,who,which等作主语时,其谓语动词的数应与句中先行词的数一致。如:Heisoneofmyfriendswhoareworkinghard./Heistheonlyoneofmyfriendswhoisworkinghard.6、如果集体名词指的是整个集体,它的谓语动词用单数;如果它指集体的成员,其谓语动词就用复数形式。这些词有family,class,crowd,committee,population,audience等。如:ClassFourisonthethirdfloor./ClassFourareunabletoagreeuponamonitor.注意:people,police,cattle等名词一般都用作复数。如:Thepolicearelookingforthelostchild.7、由“alotof,lotsof,plentyof,therestof,themajorityof+名词”构成的短语以及由“分数或百分数+名词”构成的短语作主语,其谓语动词的数要根据短语中后面名词的数而定。如:Therearealotofpeopleintheclassroom./Therestofthelectureiswonderful./50%ofthestudentsinourclassaregirls.注意:anumberof“许多”,作定语修饰复数名词,谓语用复数;thenumberof“…的数量”,主语是number,谓语用单数。8、在倒装句中,谓语动词的数应与其后的主语一致。如:Therecomesthebus./Onthewallaremanypictures./Suchistheresult./Sucharethefacts.(二)逻辑意义一致原则:逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时主语形式为单数,但意义为复数;有时形式为复数,但意义为单数)。1、what,who,which,any,more,all等代词可以是单数,也可是复数,主要靠意思来决定。如:Whichisyourbag?/Whichareyourbags?/Allisgoingwell./AllhavegonetoBeijing.2、表示“时间、重量、长度、价值”等的名词的复数作主语时,谓语动词通常用单数形式,这是由于作主语的名词在概念上是一个整体,如:Thirtyminutesisenoughforthework.3、若英语是书名、片名、格言、剧名、报名、国名等的复数形式,其谓语动词通常用单数形式。如:“TheArabianNights”isaninterestingstory-book.4、表数量的短语“oneandahalf”后接复数名词作主语时,其谓语动词可用单数形式(也可用复数。如:Oneandahalfapplesis(are)leftonthetable.5、算式中表示数目(字)的主语通常作单数看待,其谓语动词采用单数形式。如:Twelvepluseightistwenty./Fifty-sixdividedbyeightisseven.6、一些学科名词是以–ics结尾,如:mathematics,politics,physics以及news,works等,都属于形式上是复数的名词,实际意义为单数名词,它们作主语时,其谓语动词要用单数形式。如:Thepaperworkswasbuiltin1990./Ithinkphysicsisn’teasytostudy.7、trousers,glasses,clothes,shoes,等词作主语时,谓语用复数,但如果这些名词前有a(the)pairof等量词修饰时,谓语动词用单数。如:Myglassesarebroken./Thepairofshoesunderthebedishis.8、“定冠词the+形容词或分词”,表示某一类人时,动词用复数。(三)就近一致原则:在英语句子中,有时谓语动词的人称和数与最近的主语保持一致。1、当两个主语由either…or,neither…nor,whether…or…,notonly…butalso连接时,谓语动词和邻近的主语一致。如:Eithertheteacherorthestudentsareourfriends./Neithertheynorheiswhollyright./Isneitherhenortheywhollyright?2、therebe句型be动词单复数取决于其后的主语。如果其后是由and连接的两个主语,则应与靠近的那个主语保持一致。如:Therearetwochairsandadeskintheroom..注意:Here引导的句子用法同上。练习:1.I,who____yourfriend,willtrymybesttohelpyouwithyourEnglish.A.amB.isC.areD.be2.Therich____notalwayshappy.A.areB.isC.hasD.have3.NeitherTomnorJackandI____hisstudents.A.areB.amC.isD.was4.Maryaswellashersisters____ChineseinChina.A.arestudyingB.havestudiedC.studiesD.study5.NeithermyfathernorI____athome.A.amB.isC.areD.be6.NotonlymybrotherbutalsoI____goodatpainting.Bothofus____goodpainters.,A.are;areB.am;amC.ani;areD.is;is7.Every'boyandeverygirl____toattendtheeveningparty.A.wishB.wishesC.islikeD.like8.Over80percentofthepopulationofChina____peasants.A.wasB.isC.wouldbeD.are9.ThepopulationofChina____largerthanthatof.anyothercountryintheworld.A.isB.areC.hasD.have10.Everymeans____triedbutwithoutanyresult.A.havebeenB.istobeC.aretobeD.hasbeen11.Alice,togetherwithtwoboys,____forhavingbrokentherule.A.waspunishedB.punishedC.werepunishedD.beingpunished12.TheLeaguesecretaryandthemonitor____askedtoattendthe.meetingthisafternoon.A.isB.wasC.areD.isbeing13.Thegreatwriterandprofessor____.A.isanoldmanB.arebotholdmenC.isanoldmanandayoungmanD.weretwoChinese14.There____apen,twopencilsandthreebooksonthedesk.A.areB.isC.hasD.have15.Alargenumberofstudentsinourclass____girls.A.areB.wasC.isD.be16.Thenumberofdeer,mountainlionsandwildroses____muchifpeopleleavethingsastheyare.A.doesn'tchangeB.don'tchangeC.changeD.changed17.TheArabianNights____wellknowntotheEnglish.A.isB.areC.wasD.were18.ChairmanMao'sworks____published.A.hasbeenB.havebeenC.wasD.is19.Achemicalworks____builtthere.A.istobeingB.havebeenC.weretoD.hasbeen20.TheOlympicGames____heldevery____years.A.is;fourB.are;fourC.is;fiveD.are;five21.TheUnitedStatesofAmericaoneofthemostdevelopedcountriesintheworld.A.isB.areC.wasD.were22.Heistheonlyoneofdiestudentswho____elected.A.areB.haveC.hasD.is23.Theisisoneofthemostinterestingquestionsthat____asked.A.haveB.hasC.havebeenD.hasbeen24.Manyaman____cometohelpus.A.haveB.hasC.isD.are25."All____presentandall____goingonwell,"ourmonitorsaid.A.is;isB.are;areC.are;isD.is;are26.Thepolice____themurderereverywherewhenhesuddenlyappearedinatheatre.A.issearchingforB.weresearchingforC.aresearchingforD.weresearching27.Yourtrousers____dirty.Youmusthave____washed.A.is;ilB.are;itC.are;themD.is;them28.Thispairoftrouseis____toolongforhim.A.isB.beC.areD.were29.Oneandahalfbananas____leftonthetable.A.isB.areC.hasD.have30.Eighttimeseight____sixty-four.A.isB.areC.getD.equal情态动词1情态动词的语法特征

---Yes,youcan./No,youcan't.2)在否定,疑问句中表示推测或怀疑。 Hecouldn'tbeabadman. 他不大可能是坏人。3比较may和might1)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,butheisn'tverysureyet. A.must B.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must1) 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:don'thaveto 表示"不必" mustn't 表示"禁止", Youdon'thavetotellhimaboutit. 你不一定要把此事告诉他。 Youmustn'ttellhimaboutit. 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。 Ididn'thearthephone.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。 ---Whydidn'tyouanswermyphonecall? ---Well,Imusthavebeensleeping,soIdidn'thearit.5)否定推测用can't。 IfTomdidn'tleavehereuntilfiveo'clock,hecan'tbehomeyet. 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。 Idon'tknowwheresheis,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can't,couldn't表示。 Mikecan'thavefoundhiscar,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)needn'thavedonesth 本没必要做某事 Idressedverywarmlyforthetrip,butI needn'thavedoneso.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.You'dbetterputonmycoat. She'dbetternotplaywiththedog.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.doyourather B.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,won'tyou是一种委婉语气。 Won'tyousitdown?12情态动词的回答方式 问句 肯定回答 否定回答Needyou…? Yes,Imust. No,Ineedn'tMustyou…? /don'thaveto.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___.I'vetoldhimalready. A.needn't B.wouldn't C.mustn't D.shouldn't 答案A。needn't不必,不用。wouldn't将不,不会的。mustn't禁止、不能。shouldn't 不应该。本题为不需要,不必的意思,应用needn't。3)---Don'tforgettocometomybirthdaypartytomorrow. ---______. A.Idon't B. Iwon't C.Ican't D.Ihaven't 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? Shedidn'tusetoplaytennisbeforeshewasfourteen. 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./todosth2)情态动词:need,只用原形need后加do,否定形式为neednot。 Needyougoyet? Yes,Imust./No,Ineedn't.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练习:1.He?______?youmorehelp,eventhoughhewasverybusy.??A.mighthavegiven??B.mightgive??C.mayhavegiven??D.maygive2.Jenny______?havekeptherword.Iwonderwhyshechangedhermind.??A.must?????B.should????C.need????D.would3..-CouldIborrowyourdictionary???-Yes,ofcourseyou_________???A.might????B.willC.can??D.should4.ItoldSallyhowtogethere,butperhapsI______forher.??A.hadtowriteitout?????????B.musthavewrittenitout??C.shouldhavewrittenitout????D.oughttowriteitout5.—ShallItellJohnaboutit????—No,you______.I'vetoldhimalready.??A.needn't????????B.wouldn'tC.mustn't??????????D.shouldn't6.─Therewerealreadyfivepeopleinthecarbuttheymanagedtotakemeaswell.???─It______?acomfortablejourney.???A.can'tbe???????????B.shouldn'tbe???C.mustn'thavebeen???????D.couldn'thavebeen7.It'snearlyseveno'clock.Jack______?behereatanymoment.???A.must?????B.need??????C.should????D.can8..Whenhewasthere,he______gotothatcoffeeshopatthecornerafterwork???everyday.??A.would???????B.shouldC.hadbetter????????D.might9..Sir,you_____besittinginthiswaitingroom.Itisforwomenandchildrenonly.??A.oughtn'tto??????B.can'tC.won't?????D.needn't10.Thefirespreadthroughthehotelveryquicklybuteveryone______getout.??A.hadto????B.would????C.could????D.wasableto11.--WhencanIcomeforthephotos?Ineedthemtomorrowafternoon.??--They_____bereadyby12:00.??A.can??B.should??C.might??D.need12..--IstayedatahotelwhileinNewYork.???--Oh,didyou?You_____withBarbara.??A.couldhavestayed??B.couldstayC.wouldstay????????D.musthavestayed13.-Willyoustayforlunch???-Sorry,_____,Mybrotheriscomingtoseeme.??A.Imustn't???B.Ican't????C.Ineedn't???D.Iwon't14.SorryI'mlate.I______haveturnedoffthealarmclockandgonebacktosleepagain.??A.might????B.should????C.can????D.will15.Ishouldhavebeenthere,butI_______notfindthetime.A.would????B.could????C.might????D.should?16.MysistermethimattheGrandTheatreyesterdayafternoon,sohe___yourlecture.??A.couldn'thaveattended??????B.needn'thaveattended??C.mustn'thaveattended??????D.shouldn'thaveattended17.---AreyoucomingtoJeff'sparty? ---I'mnotsure.I________gototheconcertinstead.
