Grammar动词ing.ppt

,一.动名词做主语的用法动名词做主语往往表示经常性、习惯性的动作,在口语中也可以表示具体的动作。如：Seeingisbelieving.Helpingherismyduty.Talkingmendsnoholes.空谈无济于事。,动名词,Grammar,Workingwithyouisapleasure.和你一起工作是一种乐趣。动名词做主语和不定式做主语一样，也可以用it作形式主语。如：Itsrathertiringwalkingaroundinacity.在下面的句子结构中，常用it作形式主语，而把真正的主语动词-ing形式后置：Itis后接nouse,nogood,awasteof等名词。,不定式做主语往往表示具体的特别是将来的动作。如：Itsnousecryingoverspiltmilk.覆水难收。Herealizedthattogoonlikethiswaswrong.,（指抽象动作）,（指具体动作）,【考例】,WhatdoyouthinkmadeMarysoupset？_hernewbicycle（1997上海高考题）A.AsshelostB.LostC.LosingD.Becauseoflosing,解析：losinghernewbicycle是句子的主语，谓语madehersoupset被省略，losing在此表示具体的动作。,二.动名词作宾语的用法1作及物动词的宾语:有些动词或短语动词后常用动名词作宾语。如admit,appreciate,avoid，cantstand（不能忍受）,consider，delay,devoteto,dislikeenjoy，escape,excuse,feellike,finish,forgive,getdownto,giveup,imagine.,insiston,keep(on),lookforwardto,mention,mind,miss（错过）,payattentionto,practice,putoff,stickto,suggest等等。Thegirlpracticesplayingtheviolineverymorning.Headmittedmakingaseriousmistake.,2.当need,want,require,作“需要”解释时,后面接doing,而且与句子主语有逻辑上的动宾关系,但这个动名词用主动式表达被动意义。Yourhairwantscutting.你的头发该理了。Thefloorrequireswashing.地板需要冲洗。,动词need,require,want意为“需要”时，后跟动名词的主动式或不定式的被动式作宾语，意义没有区别。如：Thewindowneedsrequireswantscleaningtobecleaned,Shelooksforwardeveryspringto_theflower-linedgarden（1995上海高考题）A.visitB.payingavisitC.walkinD.walkingin,解析：考查短语动词lookforwardto后跟动名词作宾语的用法。,3.在allow,advise,forbid,permit后直接跟动名词作宾语，如果有名词或代词作宾语，则构成“allowadviseforbidpermit名词代词不定式（宾语补足语）”之形式。如：WedontallowsmokinghereWedontallowanybodytosmokehere,4.动词forget,goon,mean,regret,remember,stop,try,beusedto,canthelp后跟动名词和跟不定式区别较大，须注意。forget,regret,remember后跟动名词，动名词表示已经发生的动作；后跟不定式表示将要发生的动作。,【考例】,LetshavearestNotnowIdontwanttostop_yet（MET1985）A.studyB.tostudyC.forstudyingD.studying,解析：stopstudying意为“停止学习”。,LetmetellyousomethingaboutthejournalistsDontyouremember_methestoryyesterday？（1999上海高考题）A.toldB.tellingC.totellD.tohavetold,解析:remembertellingme意为“记得曾经告诉过我”。,5.作及物动词词组的宾语，如putoff,giveup,feellike,keepon,insiston,canthelp（情不自禁），beusedto（习惯于）等。Ifeellikegoingtothemoviethisevening.Peoplekeptoncomingtothehospitaltoseehim.,6.作介词的宾语。介词后的动词需用动名词形式。Ihaventsucceededinpersuadinghim.Healwaysthinksmuchbeforedoinganything.,7.在形容词worth后用动名词，且与句子主语有逻辑上的动宾关系，但这个动名词需用其主动式表示被动意义。Thefilmisworthseeing.这部电影值得看。Theplaceisworthvisiting.那个地方值得游览。,练习：1.Keepon_andyouwillsucceed.A.atryB.tryC.triingD.trying2.Hisparentsinsiston_tocollege.A.heshouldgoB.hegoC.hisgoingD.himtogo,3.Thestorywassofunnythatwe_.A.couldnthelplaughB.cantbutlaughC.couldnthelplaughingD.couldnthelpbuttolaugh,4.Thoughitsoundsabittoodear(昂贵),itisworth_.A.beingboughtB.buyingC.tobuyD.buyingit5.Hedevotedhislifeto_theatomictheory.A.studyB.bestudiedC.studyingD.havestudied,6.Wearebothlookingforwardto_nextweek.A.goingonvocation(休假)B.goonvocationC.begoingonvocationD.havegoneonvocation,7.Youmustpayattentionto_theworksofLuXun.A.readB.readingC.readerD.beread8.Youshouldworktonightinsteadof_TV.A.towatchB.youwatchingC.youwatchD.watching,9.Themicroscopeisusedfor_minute(微小的)objects.A.examiningB.beingexaminedC.examinedD.examine10.Mikehasgotused_uplateatnight.(stayup)A.tositB.XC.tosittingD.sittin
