第四章非谓语动词
一、不定式1.不定式作主语不定式可直接放在句首作主语。有时也用it作形式主语,把真正的主语不定式放在后面,以避免头重脚轻,保持句子结构的平衡。【例1】________Englishtodayisthemostimportanttasktome.A.Study B.BeingstudiedC.Studied D.Tostudy答案D【例2】Itismyhonor________heretospendsometimewithyou.A.tobeinvited B.invitingC.beinginvited D.toinvite答案A2.不定式作表语不定式作表语,通常说明或解释主语的内容,也可表示将来的动作。【例3】Thepurposeofnewtechnologyistomakelifeeasier,________itmoredifficult.A.notmaking B.notmakeC.nottomake D.tonotmake答案C【例4】Todaymyjobis________alltheflowersinthegarden.A.water B.havingwateredC.towater D.watered答案C3.不定式作宾语英语中有些动词常跟不定式作宾语。这类动词有:want,wish,hope,expect,agree,decide,learn,pretend,ask,promise,plan,refuse,beg,demand,manage,offer,prepare,claim,struggle等。【例5】Weagreed________here,butsofarshehasnotturnedupyet.A.havingmet B.meetingC.tomeet D.tohavemet答案C【例6】Whenhisfathercameback,theboypretended________hishomework.A.doingB.todoC.doneD.tobedoing答案D【例7】ThechildrentalkedsoloudlyatdinnertablethatIhadtostruggle________.A.tobeheard B.tohearC.beingheard D.hearing答案A4.不定式作宾补(1)有些动词(短语)后面常接带to的不定式作宾补。这类动词有:consider,get,remind,advise,allow,ask,beg,encourage,force,invite,expect,order,permit,persuade,require,want,warn,wish,teach,cause,tell,command,callon,counton,relyon,dependon,longfor,waitfor,wouldlike等。但hope,suggest,agree,demand,arrange等动词后不能接sb.todosth.结构。【例8】Wecan'tcountonamanlikeJim________usthenecessaryhelp.A.togive B.givingC.tobegiven D.given答案A(2)有些动词,主要是感官动词和使役动词,它们的后面可接不带to的不定式作宾补,如:see,notice,observe,feel,hear,have,make,let等,但如果是在被动语态的句子中,就要用带to的不定式作主补。【例9】Myparentshavealwaysmademe________aboutmyself,evenwhenIwastwelve.A.feelingwell B.feelinggoodC.feelwell D.feelgood答案D5.不定式作定语(1)不定式用在thefirst,thesecond,thelast,theonly等短语后面作定语。【例10】Johnwasthelastman________dinnerinourfamily.A.tobeinvitedfor B.tobeinvitedtoC.invitedfor D.invitingto答案B(2)不定式作定语,与被修饰的中心词之间常表现为主谓关系或动宾关系。ThenexttraintoarrivewasfromNewYork.(主谓关系)Itwasagametoberemembered.(动宾关系)【例11】Thatistheonlywaywecanimagine________theoveruseofwaterinstudents'bathrooms.(2010·上海)A.reducing B.toreduceC.reduced D.reduce答案B6.不定式作状语(1)作原因状语。不定式常可跟在某些形容词或动词后面作原因状语。【例12】Wewereastonished________thetemplestillinitsoriginalcondition. (2010·辽宁)A.finding B.tofindC.find D.tobefind答案B(2)作目的状语。不定式作目的状语既可放在句首也可放在句尾。但为了加强语气,也可用“soastodo”或“inordertodo”结构作目的状语。inorderto既可放在句首也可放在句尾,soasto一般不置于句首。【例13】WithFather'sDayaroundthecorner,Ihavetakensomemoneyoutofthebank________presentsformydad.

(2010·北京)A.advertised B.tobeadvertisedC.advertising D.havingadvertised答案A【例34】Thetrafficrulesaysyoungchildrenundertheageoffourand________lessthan40poundsmustbeinachildsafetyseat.
