非谓语动词专题1.动词不定式的构成动词不定式的基本形式是“to+动词原形”，有时可以不带to。动词不定式保留有动词的特征，可以有自己的宾语和状语，从而构成动词不定式短语，如：Hetriedtoworkouttheprobleminfiveminutes.不定式有不同的时态和语态。时态形式主动语态被动语态一般式todotobedone进行式tobedoing完成式tohavedonetohavebeendone完成进行式tohavebeendoing考点1不定式的一般式、进行式和完成式1.不定式的一般式表示动作与谓语动词的动作同时发生或在其后发生。Sheappearstobesatisfied.OurheadmasterisgoingtoShanghaitoattendameeting.2.不定式的进行式表示动作正在进行Theyseemtobegettingalongquitewell.3.不定式的完成式表示过去已完成的动作，还可表示过去没有实现的愿望。Youappeartohaveknownaboutit.Imeanttohavetelephoned,butIforgot.(=Ihadmeanttotelephone…)4.不定式的完成进行式表示的动作在谓语动词的动作之前就已经发生，并一直延续着。Theboywashappytohavebeenstayingwithhisuncle.考点2不定式的被动形式不定式有两种形式的被动式：tobedone和tohavebeendone。当不定式的逻辑主语是不定式动作的承受者时，不定式一般用被动形式。如果不定式的逻辑主语是动作的执行者，不定式用主动式。Iwishtobelovedandrespectedbyall.ThisnovelissaidtohavebeentranslatedintoEnglish.考点3不定式的否定式动词不定式的否定式是在动词不定式前加not或never构成的。Soastodosth和inordertodosth的否定式是将否定词置于不定式符号to之前。HepretendednottohaveseenmewhenIpassedby.Mr.Smithwarnedhisdaughternevertodriveafterdrinking.Hestudieshardinordernottofallbehindtheotherclassmates.达标训练一、单项选择1.WithFather’sDayaroundthecorner,Ihavetakensomemoneyoutofthebank_________presentsformydad.AbuyBtobuyCbuyingDtohavebought2._____asanOlympicevent,asportmustbeplayedinatleast75countriesonatleast4continents.AToacceptBHavingacceptedCTobeacceptedDAccepting3.Duetotheheavyrainandflooding,tenmillionpeoplehavebeenforced__________theirhomes.AleavingBtoleaveCtobeleftDbeingleft4.Ifeelgreatlyhonored___________intotheirsociety.AtowelcomeBwelcomingCtobewelcomedDwelcomed5.Havingatripabroadiscertainlygoodfortheoldcouple,butitremains__________whethertheywillenjoyit.AtoseeBtobeseenCseeingDseen6.Robertissaid___________abroad,butIdon’tknowwhatcountryhestudiedin.AtohavestudiedBtostudyCtobestudyingDtohavebeenstudying7.Whenmothercamein,LittleTompretended_____inhisstudy.AtoreadBtohavereadCtobereadingDtoberead8.Idon’tnowwhetheryouhappen_______,butI’mgoingtostudyintheUSAthisSeptember.AtobeheardBtobehearingCtohearDtohaveheard19.Doletyourmotherknowallthetruth.Sheappears__________everything.AtotellBtobetoldCtobetellingDtohavebeentold10.Tofetchwaterbeforebreakfastseemedtomearule___________.AtoneverbreakBnevertobebrokenCnevertohavebrokenDnevertobebreaking二、词语填空：用动词的适当形式填空1.Youweresillynot________________(lock)yourcar.2.Welookedeverywhereforthekeys,buttheyarenowhere________________(find)3.Hisfirstbook_________________(publish)nextmonthisbasedonatruestory.4.______________(complete)theprojectintime,thestaffwereworkingatweekends.5.----IsBobstillperforming?----I’mafraidnot.Heissaid_________________(leave)thestagealreadyashehasbecomeanofficial.6.Thefluisbelieved____________________(cause)byvirusesthatliketoreproduceinthecellsinsidethehumannoseandthroat.三、完成句子：用不定式的适当形式完成下列句子1.我们的校长要去上海参加一个会议。OurheadmasterisgoingtoShanghai_____________________________________________2.我希望受到大家的爱戴和尊敬Iwish___________________________________________andrespected...
