newsonTVhasbecomearoutineforme.在电视上看新闻已经成了我的一种日常习惯。一、动词-ing形式作主语Going
to
Hangzhoubytraintakesabout16hours.乘火车去杭州要16个小时。Asking
awoman’sageisimpoliteinourcountry.在我们国家问一个女人的年龄是不礼貌的。
GoingtoHangzhoubytraintak2.-ing形式作主语时常后置,此时须用it作形式主语,用形容词或名词作表语。常见的名词或名词短语有:nouse,nogood,fun,hardwork,ahard/difficultjob,awasteoftime等;形容词有:dangerous,worthwhile,useless等。如:It’snousemakinganexcuseforthis.为这件事找借口是没有用的。2.-ing形式作主语时常后置,此时须用itIt’sawasteoftimetalkingaboutsuchauselessthing.谈论这样无用的事情简直是浪费时间。It’sdangerousswimmingintheseaonwindydays.有风的天气在海里游泳是危险的。Itisworthwhilediscussingthequestion.这个问题值得讨论。It’sawasteoftimetalkinga
不定式作主语往往表示具体的特别是将来的动作。如:
It’snousecryingoverspiltmilk.Herealizedthattogoonlikethiswaswrong.(指抽象动作)(指具体动作)不定式作主语往往表示具体的特别是将来的动作。如:(指注意:1、动名词作主语表单数概念,谓语动词用单数形式。
Walkingaftersupperisgoodforyourhealth.2、动名词的复合结构作主语动名词的复合结构是指物主代词、名词所有格是动名词逻辑上的主语、动名词是其逻辑上的谓语。
Yourcomingmadeushappy.Yourfather’scookingisverygood.注意:考例
1.—WhatdoyouthinkmadeMarysoupset?
—__________hernewbicycle.
A.Asshelost
B.LostC.Losing
D.Becauseoflosing
解析:答案是C。losinghernewbicycle是句子的主语,谓语madehersoupset被省略;losing…在此表示具体的动作。考例1.—Whatdoyouthink2.Listeningtoloudmusicatrockconcerts
____causedhearinglossinsometeenagers.(2010湖南卷)
A.isB.areC.hasD.have 答案:C解析:根据动名词短语作主语,句子的谓语动词用单数形式,由此排除B、D两项,根据主语与caused的主动关系,排除A项2.Listeningtoloudmusicat3.It’snouse_____withouttakingaction.(2011上海)A.complain B.complainingC.beingcomplained D.tobecomplained答案:B解析:考查非谓语动词。句意为:光抱怨而不采取任何行动是没用的。根据句型It’snousedoingsth.“做某事没有意义”,可知选B。3.It’snouse_____withoutt3.在therebe结构中作主语,这种结构的意思相当于“Itisimpossibletodo…”。如:若要人不知,除非己莫为。Thereisno
hiding
ofevilbutnottodoit.这种事开不得玩笑。
Hereisno
joking
aboutsuchmatter.无法知道他什么时候离开Therewasno
knowing
whenhewouldleave.3.在therebe结构中作主语,这种结构的意思动名词与不定式做主语时的比较: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。如:还是个孩子的时侯,她就觉得探视病人是一种责任,也是一种愉悦。Asachild,shefeltthat
visitingsickpeople
wasadutyandapleasure.到美国人家里做客对我来说将是一个极好的经历。Being
aguest
inanAmericanhomewillbeagoodexperienceforme.动名词与不定式做主语时的比较:一直不做就是作恶。
Doingnothing
isdoingill.他说:“继续这样下去是无用的。”
Hesaid,“To
go
on
like
this
isuseless.”我很荣幸被邀请参加这个晚会。
It’sanhonorforme
to
be

totheparty.一直不做就是作恶。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……归纳:常用-ing形式作主语的句型有:Thereisnosenseindoing
做……没有道理Thereis/wasnousedoing
干……无意义Thereis/wasnothingworsethandoing没有比……更糟的Thereis/wasnopointdoing
干……无意义我们不知道要去哪儿。Therewasnoknowing
wherewewouldgo.做这件傻事毫无意义。Thereisno
point
doing
suchasillything.Thereisnosenseindoing做…注意:
Thereisnoneedtodosth
干……没必要,在此句式中todo不可换为doing.没有必要告诉她。Thereisnoneedtotellher.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。我姐姐病了,使我很担心。Mysister’sbeingillmademeworried.你正确未必就意味着我错了。Yourbeingrightdoesn’tnecessarilymeanmybeingwrong.注意:Thereisnoneedtodosth二、动名词用作宾语动名词作宾语有两种情况。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:我不能不去。Ican’t
avoidgoing.你是否考虑过找一位挚友?Haveyou
considered
looking
for
onespecialfriend?二、动名词用作宾语我们必须设法避免犯同样的错误。Wemusttrytoavoidrepeatingthesamemistake.晚饭后你想和我一起散步吗?Doyoufeellikehavingawalkwithmeaftersupper?人们忍不住嘲笑那个愚蠢的人。Peoplecouldn’thelplaughingfoolishman.
这类动词还有:excuse,fancy,giveup,putoff,risk,insiston,lookforward,feellike等。我们必须设法避免犯同样的错误。注意:
当need,want,require,worth后面接动词-ing也可以表示被动。
Yourhairwantscutting.

2.既可接动名词又可接不定式作宾语的动词,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,
如:我记得我已把信寄了。Irememberpostingtheletter.我会记着去寄信的。I’llremembertoposttheletter.我永远不会忘记见到过那位著名作家。Ishallneverforgetseeingthefamouswriter.C.在动词forget,remember,regret不要忘了给你母亲写信。Don’tforgettowritetoyourmother.我真后悔没赶上那次报告会。Iregretmissingthereport.我遗憾地告诉你我不能接受你的建议。IregrettosayIcan’ttakeyouradvice.不要忘了给你母亲写信。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)。如:我们必须设法及时把一切搞好。Wemusttrytogeteverythingdoneintime.我们用别的方法做这工作试试。
Let’strydoingtheworkinginsomeotherway.我并不想叫你生气。Ididn’tmeantomakeyouangry.你的计划意味着要花费几个小时。Yourplanwouldmeanspendinghours.D.在try,mean之后,意义各不相同,如trE.goondoing和goontodogoondoing继续做一直在做的事;goontodo接着做另一件事。如:请接着做这同一个练习。Pleasegoondoingthesameexercise.请做另外一个练习。Pleasegoontodotheotherexercise.F.stopdoing与stoptodo:Stopdoing停止做,stoptodo停下正在干的事去干另一件事。如:我们停止了交谈。We
