非谓语动词错误例析英语中的非谓语动词是高考的语言重点，是历届高考试题中的必考内容，也是中学生在校学习英语的过程中深感棘手的难点。下面是学生经常出错的非谓语动词的一些例子。【例1】WIttookhertwohoursfinishingherhomework.RIttookhertwohourstofinishherhomework.【例2】WItisnousetoregretwhathasbeendone.RItisnouseregrettingwhathasbeendone.【分析】不定式,动名词均可以用作句子的主语.其区别不大,常可互换.但在某些句型中的主语用动名词(例2),某些句型中主语永不定式(例1)都属于习惯用法,一般不宜互换。【例3】WMostofthestudentsenjoytoreadnovels.RMostofthestudentsenjoyreadingnovels.【例4】WHealwaysrefusesdoingwhatheisunwillingto.RHealwaysrefusestodowhatheisunwillingto.【分析】不定式,动名词均可以作宾语。但并非每个及物动词后都可以接不定式或者都能解动名词。要根据各个动词的搭配结构选定不定式活动名词。1.某些动词后既可以接不定式又可以接动名词,其意义差别不大,可以互换。这类动词有:likelovehatedislikebeginstartcontinue等。例:Shelikesplaying(toplay)chessinhersparetime.Nobodycanbeartobelaughed(beinglaughed)atinpublic.2.某些及物动词后只能接不定式作宾语,不能接动名词作宾语如(例4)。这类动词有:hope,offer,help,expect,learn,demand,decide,refuse,ask,prepare,plan,choose,manage,pretend,fail,wish,agree等。例:Shepretended_____mewhenIpassedby.(MET89.34)A.nottoseeB.NotseeingC.TonotseeD.Havingnotseen(A)Weagreed____herebutsofarshehasn’tturnedupyet.(NMET95.19)A.learnB.TolearnC.LearnedD.Learning(B)3.某些及物动词后只能跟动名词作宾语,不能跟不定式作宾语如(例3)。这类动词有:mind,suggest,avoid,excuse,finish,allow,admit,resist,miss,enjoy,consider,imagine,advise,permit,prevent,delay,appreciate,giveup,putoff,feellike,consiston,can’thelp等。Iwouldappreciate_____backthisafternoon.MET92.18)A.youtocallB.youcallC.yourcallingD.you’recalling(C)Peoplecouldn’thelp___thefoolishemperorintheprocession.(MET83.20)A.laughatB.tolaughatC.laughingatD.laughingon(C)Thesquirrelwasluckythatitjustmissed____.(MET87.38)A.catchingB.tobecaughtC.beingcaughtD.tocatch(C)【例5】WNobodywasallowedsmokinghere.RNobodywasallowedtosmokehere.【分析】某些动词如:allowpermitforbidadvisecontinue等后面必须接动名词作宾语，但也可以接不定式的复合宾语。本句为被动语态，后面的非谓语动词为不足语。CharlesBabbageisgenerallyconsidered____thefirstcomputer.(NMET93.34)A．toinventB.inventingC.tohaveinventedD.havinginvented(C)4.某些动词或词组后接动名词主动形式表被动意义。这类动词有：needwantrequirebeworth等。----Whatdoyouthinkofthebook?(MET89)----Oh,excellent.It’sworth______asecondtime.A.toreadB.tobereadC.rea
