havecomeNeithernor重点语法动词不定式作主语【思维导图】1.动词不定式作主语时,谓语动词用单数。Tolookafterthesenaughtyboysisreallydifficult.照看这些淘气的男孩真的很难。Toplayfireisverydangerous.玩火是很危险的。2.为了避免头重脚轻,常用it作形式主语放在句首,作主语的不定式常置于句末。Itwouldbebetterforyoutogothere.你还是去那里的好。It’seasyforhimtoworkoutthismathproblem.对他来说解出这道数学题很容易。常见的句型有:(1)itis+adj.+todo...Howeverhardyoutry,itisdifficulttoloseweightwithoutcuttingdowntheamountyoueat.不管你多么努力,很难在不减少食物摄入量的情况下减肥。Ithinkthatitisimpossibletobetherebeforeeight.我觉得在8点之前赶到那里是不可能的。注意:若要说明不定式表示的动作的发出者的话,要在不定式前加for引起的短语,构成“for+名词(或代词宾格)+不定式”短语,这一短语被称为不定式的复合结构。在“itis+adj.+不定式复合结构”句型中,当其中的形容词是说明逻辑主语的性质、品质时,要由of引出逻辑主语,不能用for。这类形容词主要有clever,foolish,kind,nice,polite,silly,stupid,wise等。Itwasreallyverykindofyoutogivemealifthome.你能送我回家真是太好了。Itisfoolishofthemtoturndowntheproposal.他们拒绝那个建议实在是太愚蠢了。(2)itis+n.+todo...Webelieveitisourdutytohelpthoseinneedtomaketheworldweliveinabetterplace.我们相信我们有义务帮助那些有困难的人来使我们居住的这个世界变得更美好。Itisanhonourformetobeinvitedtospeakatthemeeting.被邀请在会上讲话我感到非常荣幸。(3)ittakessbsometimetodo...Ittakesthemseveraldaystoadaptthemselvestotheclimateattheheights.他们花了数天的时间才适应高地的气候。Ittookusawholeweektogothroughtheforest.我们花了整整一星期才穿过那片森林。3.不定式可以和when,where,how,what,whether等连用,在句子中作主语、宾语和表语,而动词-ing形式则不能。Wheretoputtheboxseemshardtodecide.很难决定把这个箱子放在哪里。Whethertodoithasn’tbeendecided.是否做这件事还没定下来。【拓展】动词不定式和动词-ing形式作主语的异同点:1.动词-ing形式和不定式作主语的相同点(1)不定式和动词-ing形式作主语时,常常为了保持句子的平衡,用it来作形式主语,如:ItisnoteasytolearnEnglishwell.学好英语不容易。Itisnouseaskinghimforhelp.向他求助是没有用的。(2)如果主语用了不定式,表语和宾语也要用不定式;主语用了动词-ing形式,表语和宾语也要用动词-ing形式,这在英语中称为对称性,如:Toseeistobelieve.=Seeingisbelieving.眼见为实。Itisbettertostayhomethantogoout.待在家里比出去要好。2.动词-ing形式和不定式作主语的不同点(1)不定式作主语常表示具体的某一动作;表示泛指或一般的抽象的概念时,多用动词-ing形式。Walkingisagoodformofexerciseforbothyoungandold.散步是一种老幼皆宜的很好的运动形式。(2)在“itisnouse/good/help/need”结构之后常用动词-ing形式作主语,而少用不定式。Itisnousecryingoverthesplitmilk.覆水难收。Itisnohelptakingthisme
