八年级英语动词不定式复习

动词不定式复习语法复习：动词不定式动词不定式(todo)是初中英语课的一个重点，也是中考要考查的一个项目。动词不定式属于非谓语动词的一种形式，很多同学经常把它和谓语动词混在一起，掌握起来有困难。下面我们对动词不定式的用法做简单归纳，帮助同学们记忆：一、动词不定式在句子中不能充当谓语，没有人称和数的变化。二、动词不定式是由“to+动词原形”构成(有时可以不带to)。动词不定式的否定形式是“not+动词不定式”(not不与助动词连用)。三、动词不定式短语具有名词、形容词和副词等的功能，可在句中用做多种句子成分。1、主语：常置于句末，而用it代替其做形式主语。Togoinforsportshelpsyoustayfit.Itisdangeroustoswiminthedeepseaonyourown.注：此句式中不定式逻辑上的主语可由for或of引出，逻辑主语由of引出时，表语的形容词为kind,nice,good,polite,clever,foolish,right,wrong等表示评价的形容词。例：It’srightofhimtorefusetheinvitation.(him为逻辑主语)2、表语：Ourdutyistoprotecttheenvironment.3、动词宾语：此种情况可按固定搭配或句式去记。例：Wouldyouliketoseemyphotos?Kevinplannedtovisithisuncle.和plan用法一样的词还有：start,want,agree,hope,begin,decide等。Ifounditverydifficulttogetajob.(it为形式宾语)4、宾语补足语：(1)在多数复合宾语及物动词后要带to。例：Iaskedafriendtoreadittome.(book4，L2)(2)在表示感觉、致使等意义的动词(see,watch,hear,feel,notice,observe,make,let,have,help等)后不带to。例：Theyheardhimsingapopsonginthemeetingroom.5、定语：动词不定式做定语放在所修饰的名词的后面。例：Ihavesomethingimportanttosay.6、形容词补足语:在表示心理、感情、评价等的形容词后，对其进行补充说明。例：Weareverygladtomeetyouagain.7、状语：表示目的、原因、程度等。例：Theybroughtinphotosoftheirfamiliesformetolookat.8、“疑问词+不定式”用法：不定式前可带what,who,which,where,when,how等疑问词，这种不定式短语在句中多用做宾语。例：Hedidn’ttellmewheretogo.不定式综合练习：一．用动词的适当形式填空（包括时态和动词的非谓语形式）1、JoeHillwrotesongs_______(keep)uptheworkers'struggle.2、Hisbrothertoldmeheenjoyed_______(play)footballverymuch.3、Stop______(talk),youwillhearsomethingstrange.4、Don'tmakehim_______(climb)thetree.5、Thisyeartheyaregoing__________(put)upanewtheatre(戏院).6、Thesebookscan't_____(return)toyou,becauseI___(notfinish)_______(read)them.7、Fatheraskedhisson_______(notplay)withfire.8、Thestudentswereasked__________(take)outapieceofpaperandwritedownthesentencesontheblackboard.9、Afterhavingarest,hewenton______(do)hishomework.10、It'stimeforyou__________(empty)thedustbin.11、Alotofinformation__________(put)intothecomputeryesterday.12、It'simportant___________(do)morningexerciseseveryday.13、Toadoctorthemostimportantthingis_________(save)lives.14、Thebossmadeus_________(work)morethantenhoursaday.15、Theprofessorhadastrangewayof________(make)hislessonslivelyandinteresting.16、(put)_______onyourcoatandbecareful___________(notcatch)acold.17、Iamsorry_______(keep)you________(wait)solong.18、How________(get)tothesciencemuseumisaquestion.19、Ittakesmehalfanhour__________(go)toschoolonfoot.20、Shewasneverheard___________(sing)sowellbefore.21、Sheoftendoes__________(shop)intheevening.22、Theystopped________(listen)tohersongsbecausetheywerefondof_______(sing).23、It'srathercold,you'dbetter_________(nottake)offyourcoat.24、It'skindofyou_________(give)seattotheoldman.25、MayIuseyourdictionaryforaminute?Iwant________(look)upanewword.26、Theywereable___________(built)thehousethemselves.27、Hewastold________(pay)attentionto(注意)hispronunciation(发音).28、Hehadalotofwork___________(do).29、Wouldyouplease__________(give)theboysomething______(eat).30、Wouldyoulikehim___________(get)somewaterforyou?31、IsawMary________(play)withhersisterunderthetree.32、Youmust________(tell)yourbrother______(bring)hisEnglishbooktoschool.33、----MrHu__________(be)inhospitalsince2daysago.----I'msorry________(hear)that.34、TheEnglishteacher________(ask)us________(write)thesenewwordsagain.35、Therewasnotime_______(read)thenewspaperatthetime.36、Tomistooyoung_________(carry)thebox.37、Stop________(write)and________(listen)totheteacher.38、It'sbetter_______(give)than_________(receive).39、Mostofthestudentsarebusy______(do)theirhomework..40、Ourteacheraskedme_________(notplay)basketball.二．把下列的定语从句和同位语从句改为不定式短语。1.Therearestillalotofdifficultieswehavetoovercome.2.Beforethemachinesleavethefactory,thereisaseriesofteststhatmustbepassed.3.AttheendofthespeechheexpressedthedesirethatheshouldcomeandworkinChinasomeday.4.Theysignedanagreementthattheyshouldexpandthetradebetweenthetwocountries.5.Thecommandergaveordersthatweshouldcrosstheriver.三.把下列的状语从句改为不定式短语。1.Shewasexcitedwhensheheardthenews.2.I’mgladIhaveseenyourmother.3.Themotherwaspleasedwhenshesawhersondoingsowellatschool.4.Hewasveryhappywhenhesawussohappy.5.Theywillbedisappointedwhentheyhearit.四.把下列的结果状语从句改为enoughto或too…to…短语。1.Theroomissolargethatitcanholdonehundredpeople.2.Theroomissosmallthatitcan'tholdonehundredpeople.3.Thetextissoeasythatachildcanunderstandit.4.Thetextissodifficultthatachildcan'tunderstandit.5.Heissoshortthathecan'tbeagoodbasketballplayer.五．单项选择()1.Theteachertoldthestudents______inclass.A.nottalkB.don’ttalkC.didn’ttalkD.nottotalk()2.“MrZhang,you’dbetter______toomuchmeat.Youarealreadyoverweight,”saidthedoctor.A.nottoeatB.toeatC.noteatD.eat()3.Wesawhim______thebuildingandgoupstairs.A.toenterB.enterC.enteringD.entered()4.Mymotheroftenasksme______early.A.getupB.gotupC.gettingupD.togetup()5.“Don’talwaysmakeMichael______thisorthat.Heisalreadyabigboy,dear.”MrBushsaidtohiswife.A.doB.todoC.doesD.did()6.Theyoungladywatchedherdaughter______ayo-yoyesterdayafternoon.A.toplaywithB.playingwithC.toplayD.plays()7.Wearetold______everywhere.It’sourdutytokeepourschoolcleanandtidy.A.nottomakemuchnoiseB.tothrowwastepaperC.todrawD.nottospit()8.Theboywastoobusy_____
