动词ing形式做主语和宾语.ppt

Unit2Grammartheuseof-ingform我们常说的现在分词和动名词是怎么回事？一、动名词的形式动词-ing形式作主语表示抽象的或泛指的动作,谓语动词用单数。如：Readingaloudisveryimportantforustolearnaforeignlanguage.两个或多个动名词短语并列作主语的时候谓语动词是单数还是复数形式?这要看叙述的是一件事还是两件以上，如果是一件事，谓语动词是单数，如果是两件事，谓语动词是复数形式。如：Goingtobedearlyandgettingupearlyisagoodhabit.WatchingTVandreadingbooksarereallyinteresting.二、功能及用法(作主语)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，worthwhile等。如：It’snousesweepingtears.Itwasawasteoftimedoingsuchathing._③在therebe+no+v-ing结构中作主语，=“Itisimpossibletodo…”表示“没法……不允许...”。如：1)Thereisnohidingofevilbutnottodoit．若要人不知，除非己莫为。2)这种事开不得玩笑。Thereis________________aboutsuchmatter.3)无法知道他什么时候离开。Therewas_____________whenhewouldleave.动名词作主语的形式主语句型4'有些动词和短语等后能接动词-ing形式作宾语，而不能接动词不定式。如：We’reconsidering_________(pay)avisittotheScienceMuseum.I’mfondof_________(collect)stampsandcoins.考虑建议盼原谅，承认推迟没得想，避免错过继续练，否认完成停能赏，不禁介意准逃亡，不准冒险凭想象。注：need,require,want作“需要”解时,后接动词-ing形式作宾语,主动形式表示被动意义,相当于tobedone。V-ing形式的复合结构注：动词-ing形式的否定形式是在其前面加not，带有逻辑主语时not应在动词-ing形式之前。如：Notcleaningherteethmadehersmellbad.Yourschoolmate’snotcominghomeintimemadeherparentsworried.Billsuggested_____ameetingonwhattodofortheShanghaiExpoduringthevacation.A.havingheldB.toholdC.holdingD.hold2.Thewomanfounditnogood_____herdaughtertoomuchmoney.A.givingB.beinggivenC.givenD.gave3._____madethestudent____interestinhisstudies.A.Beingpunished;toloseB.Punished;loseC.Beingpunished;loseD.Havingbeenpunished;lost4.OurEnglishteachersuggestedwepractise_____Englisheveryday.A.tospeakB.speakC.speakingD.spoke5.Ireallycan’tunderstand____herlikethat.A.youtreatB.youtotreatC.whytreatD.youtreating6.____thehomeworkmadehisfatherlosehistemper.A.Theboy’snothavingdoneB.TheboynothavingdoneC.Theboy’shavingnotdoneD.Theboyhavingnotdone根据括号内的汉语提示,完成下列句子。1._____________(大声朗读)inthelibraryisabadhabit.2.It’snouse_____________(像这样谈话).3.Inmymind,____________________________(进入那所著名的大学)willbetheonlywaytobecomeaworld-classwriter.4.Marygotwell-preparedforthejobinterview,forshecouldn’trisk______
