动名词一、概述?和不定式一样,动名词也是非谓语动词的一种,它通常由动词原形加-ing构成。动名词有主动和被动两种语态,有一般式,完成式和进行式三种形式。如下表所示:

动名词仍保留有动词的特征,可以和自己的逻辑主语、宾语和状语等构成动名词短语。动名词具有名词的功能,在句中可以充当主语、宾语、表语、定语等成分。?二、动名词的时态和语态形式?1.动名词的时态形式?①一般式?动名词的一般式表示动作或状态与谓语动词的动作同时发生,或者表示一种无时间性限制的经常性、习惯性的动作或状态。?HeenjoyswritinglettersinEnglish.?他喜欢用英语写信。?Manyyoungpeoplelikeplayingfootball.?许多年轻人喜欢踢足球。?②完成式?动名词的完成式表示动作或状态先于谓语动词的动作或状态,如:?Theyregrethavingbeenunabletohelpyou.?他们为没能帮上你的忙而遗憾。?Afterhavingwrittentheletter,hewenttopostit.?他写完信,就去寄它了。?Sheregrettedhavingmissedthefilm.?她后悔没有看到那部电影。?③完成进行式?动名词的完成进行时表示动作发生于谓语动作之前,并一直持续到谓语动词的动作发生之时,或继续。如:?Forgivemeformyhavingbeeninterruptingyousomuch.?原谅我打扰你这么久。2.动名词的被动式?当动名词的逻辑主语是动名词动作的承受者时,用被动式。如:?Heclimbedthroughthewindowwithoutbeingseen.?他从窗口爬进去,没有被人发现。?Sheneedstoworkwithoutbeingdisturbed(=withoutpeopledisturbher).?她要在无人干扰的情况下才能工作。?动名词的被动语态分成一般式和完成式两种。如:?Therailwayisintheprocessofbeingconstructed.?铁路在兴建中。?AfterhavingkeptaprisonerintheBastilleformanyyears,DrManettehadrecentlybeensetfree.?曼奈特医生被关在巴士底监狱许多年后,最近获释。?特别提示:-ing形式的主动形式表示被动意义?在want,need,deserve,require等动词后,总是用-ing形式的主动形式表示被动意义,相当于“tobe+过去分词”。如:?Mywatchneedsrepairing(=toberepaired).?我的手表需要修理。?Thehousewantscleaning.这房屋需要打扫。?在worth这个形容词后情形也是这样。如:?Thefilmisworthseeing.这部影片值得一看。?Theplaceisworthvisiting.那个地方值得一游。?三、动名词的否定式?动名词的否定式通常是在动名词前加否定词not。例如:?Iapologizeformynothavingkeptpromise.?我没能遵守诺言,十分抱歉。?Iregretnotbeingabletohelpyou.?我很抱歉不能帮助你。?1.作主语?动名词作主语时,句子有两种形式:?(1)动名词直接置于句首主语的位置上。?Playingtricksonothersissomethingweshouldneverdo.?捉弄别人是我们万万不能干的。?Learningnewwordsisveryimportantforme.?学习新单词对我来说非常重要。?Talkingiseasierthandoing。说比做容易。?(2)用形式主语it,把真正的主语——动名词结构移置句尾。但这种句子形式有一定的限制,作表语的只能是某些形容词或少数名词,如useful,useless,good,fun,nouse,worth等。例如:?ItisuselesstryingtoarguewithShylock.?和夏洛克争辩是没有什么用的。?It’sworthmakingtheeffort.?这事值得去做。?Isitanygoodtryingtoexplain??想再解释一次有好处吗??Itispleasantworkingwithyou.?跟你在一起工作是令人愉快的。?(3)在therebe结构中作主语,这种结构的意思相当于“Itisimpossibletodo...”。例如:?Thereisnohidingofevilbutnottodoit.?若要人不知,除非己莫为。?Thereisnojokingaboutsuchmatter。?这种事开不得玩笑。?Therewasnoknowingwhenhewouldleave.?无法知道他什么时候离开。?注意:动名词与不定式作主语时的比较:?动名词表示的动作通常是一个泛指的动作,不定式则通常表示具体的动作。例如:?Asachild,shefeltthatvisitingsickpeoplewasadutyandapleasure.?还是个孩子的时候,她就觉得探视病人是一种责任,也是一种愉悦。?BeingaguestinanAmericanhomewillbeagoodexperienceforme.?到美国人家里做客对我来说将是一个极好的经历。?Doingnothingisdoingill.?什么也不做就是作恶。?Hesaid,“Togoonlikethisisnouse.”?他说:“继续这样下去是无用的。”?It’sanhonourformetobeinvitedtotheparty.?我很荣幸被邀请参加这个晚会。?归纳:常用-ing形式作主语的句型有:?It+be+awasteoftimedoing做……是浪费时间的?Itis/wasnogood/usedoing做……是没用处的?Itis/washardly/scarcelyworthdoing做……不值得?Itis/wasworth/worthwhiledoing做……是值得的?Thereisnodoing无法……,不允许……?Thereisnosenseindoing做……没有道理?Thereis/wasnousedoing干……无意义?Thereis/wasnothingworsethandoing没有比……更糟的?Thereis/wasnopointdoing干……无意义?Therewasnoknowingwherewewouldgo.?我们不知道要去哪儿。?Thereisnopointdoingsuchasillything.?做这件傻事毫无意义。?注意:Thereisnoneedtodosth.干……没必要,在此句式中todo不可换为doing。?Thereisnoneedtotellher.没有必要告诉她。?提示:当动名词用作主语时,其逻辑主语由形容词性物主代词和名词所有格构成。?Mysister’sbeingillmadeweworried.?我姐姐病了,使我很担心。?Yourbeingrightdoesn’tnecessarilymeanmybeingwrong.?你正确未必就意味着我错了。2.作动词的宾语?动名词作宾语有两种情况。一是有些动词只能后接动名词作宾语;二是有些动词既可后接动名词也可后接不定式作宾语。?(1)只能后接动名词作宾语的动词,常见的有avoid,consider,enjoy,keep,finish,suggest,dislike,delay,escape,cannothelp,imagine,mind,miss,practise,cannotstand等。如:?Ican’tavoidgoing.我不能不去。?Haveyouconsideredlookingforonespecialfriend??你是否考虑过找一位挚友??Wemusttrytoavoidrepeatingthesamemistake.?我们必须设法避免犯同样的错误。?Doyoufeellikehavingawalkwithmeaftersupper??晚饭后你想和我一起散步吗??Peoplecouldn’thelplaughingfoolishman.?人们忍不住嘲笑那个愚蠢的人。?这类动词还有:excuse,fancy,giveup,putoff,risk等。?(2)既可接动名词又可接不定式作宾语的动词,常见的有:begin,start,continue,like,love,prefer,by,mean,forget,remember,hate等。?A.在like,love,hate,prefer等动词之后,用-ing或不定式意义上没有什么不同,只是侧重点有些不同,动名词表示泛指的动作,不定式表示具体的一次性动作。例如:?Iconsideredgoing,butIhavethiscompositiontowrite.?我考虑要去,可是我要写这篇作文。?Ienjoylearningaboutnewthingsfrompoliticstosportsandmusic.?我喜欢从政治、体育及音乐等方面学习新的事情。?Webelievethatmanymorepeoplewillprefertotravelbyair.?我们相信将会有更多的人喜欢乘坐飞机旅行。?在wouldlike/love/prefer之后,只能用不定式。例如:?I’dprefertodothattomorrow.这事我想明天再做。?I’dliketodosomeshopping,butnotduringtheday.?我倒是想去购物,但又不想白天去。?I’dlikeyoutomeetDrZhang.?我想让你见一见张医生。?Oh,Iwouldlovetobeacontestant.?噢,我倒是想做个参赛者。?B.在begin/start,continue之后,用动名词和不定式,意义无甚区别,尤其是当主语是人的时候。例如:?Jazzstarteddevelopinginthe1920sintheSouthernStates.?20年代爵士音乐在美国南部各州开始发展。?Theshipstartedtoleakandbegintofillwithwater.?船体开始出现漏洞,并开始进水。?Hankstartedtowalkthroughthecarriagestogetbacktohisseat.?汉克开始走回他自己坐的车厢。?Journalistshavetostopworkingononestoryandstartworkingimmediatelyontheimportantnewone.?新闻记者不得不停下手中所写的,立刻开始写最新的重要新闻。?当begin/start与see,think,feel,understand等动词连用时,用不定式。例如:?Theybegantounderstandhowimportanttheforestis.?他们开始明白森林有多么重要。?begin/start用进行式时,只能后接不定式。例如:?Iwasbeginningtowonderifitwaseasyenoughtogoontheclimbing.?我开始想继续往上爬会不会越来越难。?I’mstartingtoputonweightagain.?我又开始长胖了。?C.在动词forget,remember,regret之后,用动名词与不定式意义不同。动名词表示动作先于谓语发生,不定式表示后于谓语动作,例如:?Irememberpostingtheletter.?我记得我已把信寄了。?I’llremembertoposttheletter.?我会记着去寄信的。?Ishallneverforgetseeingthefamouswriter.?我永远不会忘记见到过那位著名作家。?Don’tforgettowritetoyourmother.?不要忘了给你母亲写信。?Iregretmissingthereport.?我真后悔没赶上那次报告会。?IregrettosayIcan’ttakeyouradvice.?我遗憾地告诉你我不能接受你的建议。?D.在try,mean之后,意义各不相同,如trytodo(设法),trydoing(试试),meantodo(打算,有意要做),meandoing(意思是,意味着)。例如:?Wemusttrytogeteverythingdoneintime.?我们必须设法及时把一切搞好。?Let’strydoingtheworkinginsomeotherway.?我们用别的方法做这工作试试。?Ididn’tmeantomakeyouangry.?我并不想叫你生气。?Yourplanwouldmeanspendinghours.?你的计划意味着要花费几个小时。?E.goondoing和goontodo?goondoing继续做一直在做的事;goontodo接着做另一件事。例如:?Pleasegoondoingthesameexercise.请接着做这同一个练习。?Pleasegoontodotheotherexercise.请做另外一个练习。?F.stopdoing与stoptodo?stopdoing停止做,stoptodo停下正在干的事去干另一件事。如:?Westoppedtalking.我们停止了交谈。?Westoppedtotalk.我们停了下来去谈话。3.作介词的宾语?动名词可与介词一起构成介词短语。?A.介词+动名词,如:?We’vegottothinkofwaysofchangingpeople’shabits.?我们得想些办法改变人们的习惯。?Iapologizeforbeingsoangrywithyou.?我向你道歉,刚才对你那样生气。?Afterbeingawayforseveralyears,itisastrangeexperiencetoreturntotheplaceyouwerebornandbroughtup.?离开几年之后再回到你生长的地方,感觉有点怪。?B.动词+介词+动名词,例如:?Iinsistontakingproperfoodforthisexpedition.?我坚持为这次出行带足需要的食物。?Insteadofsmiling,eachofthemmadeaface.?同学们脸上没有笑容,相反都做了怪脸。?Shewasveryinterestedinworkingforourcompany.?她对为我们公司工作很感兴趣。?下列短语中的to都是介词,所以后面跟名词或-ing形式:devoteto,objectto,payattentionto,getdownto,leadto,lookforwardto,stickto,beusedto等。?文章来源:http://m.jab88.com/j/30016.html
