非谓语动词考点◆典型陷阱题分析◆1.Everyoneinourclasswasworkinghardanddoingwhatwecould_______agoodcollege.A.enterB.toenterC.enteringD.entered【陷阱】容易误选A。有的同学一看到空格前的情态动词could就断定此处应填动词原形enter。【分析】其实正确答案应是B。此句为省略句，即在could后省略了动词do，若把句子补完整应为Everyoneinourclasswasworkinghardanddoingwhatwecoulddotoenteragoodcollege。即句中的不定式短语(toenteragoodcollege)是用作目的状语的，而不是与情态动词(could)一起构成谓语。请再看类似例句：(1)Theydidwhattheycouldtocomforther.他们尽量安慰她。(2)Theydideverythingtheycouldtosaveherlife.他们尽一切力量拯救她的性命。(3)Hestudiesashardashecouldtocatchupwithhisclassmates.他拼命学习以便赶上他的同学。值得指出的是，这也并不是说今后只要遇到类似结构的题就一定选带to不定式。请看以下试题：(4)Heranasfastashecould_____tocatchtheearlybus.A.tohopeB.hopeC.hopingD.hoped此题的答案是C不是A，其中的现在分词短语hopingtocatchtheearlybus用作伴随状语。(5)Hespenteveryminutehecould_____spokenEnglish.A.practiseB.topractiseC.practisingD.practised此题答案选C，这与前面动词spent的搭配有关，即spend…(in)doingsth。若将此句补充完整，即为HespenteveryminutehecouldspendinpractisingspokenEnglish.(6)Beforegoingabroadhedevotedallhecould____D____hisoralEnglish.A.improveB.toimproveC.improvingD.toimproving此题答案选D，注意两点：一是devote…to…是固定搭配，意为“把……贡献给……”；二是其中的to是介词，不是不定式符号，后接动词时要用动名词。2.Heknowsnothingaboutit,sohecan’thelp_______anyofyourwork.A.doingB.todoC.beingdoingD.tobedone【陷阱】容易误选B，根据can’thelpdoingsth这一结构推出。【分析】其实答案应选A。比较以下结构：can’thelptodosth=不能帮助做某事can’thelpdoingsth=禁不住做某事，情不自禁地做某事又如下面一题，答案也是B：Shecan’thelp____thehousebecauseshe’sbusymakingacake.AcleaningB.tocleanC.cleanedD.beingcleaned再请看以下试题：Whileshopping,peoplesometimescan’thelp_____intobuyingsomethingtheydon’treallyneed.A.topersuadeB.persuadingC.beingpersuadedD.bepersuaded此题应选C，句中的can’thelp意为“禁不住”（注意根据句意用被动形式）。3.Allhertime_______experiments,shehasnotimeforfilms.A.devotedtodoB.devotedtodoingC.devotingtodoingD.isdevotedtodoing【陷阱】几个干扰项均有可能误选。【分析】此题最佳答案为B。现分析如下：(1)devote意为“致力于，献身于”，主要用devote…to…或bedevotedto，其中的to是介词，不是不定式符号，故后接动词时要用动名词，不用不定式。(2)选A错误：若将do改为doing则可以。(3)选B正确：allhertimedevotedtodoingexperiments为独立主格结构，用作状语。(4)选C错误：因为allhertime与devote为被动关系，故应将devoting改为devoted。(5)选D错误：若单独看Allhertimeisdevotedtodoingexperiments，此句并没有错，但问题是逗号前后两个简单句没有必要的连接方式，所以从整体上看仍不对，假若在后一句的句首加上and或so，则可选D，或将D将中的is改为being也可选它。请做以下类似题（答案均选A）：(1)Allthepreparationsfortheproject______,we’rereadytostart.A.completedB.havebeencompletedC.hadbeencompletedD.beencompleted(2)Such_______thecase,Icouldn’thelpbut______him.A.being,supportB.was,supportC.hasbeen,supportingD.is,tosupport比较以下各题，答案选B，因为句中使用了并列连词and：(1)Allthepreparationsfortheproject______,andwe’rereadytostart.A.completedB.havebeencompletedC.hadbeencompletedD.beencompleted(2)Such_______thecase,Icouldn’thelpbut______him.A.being,supportB.was,supportC.hasbeen,supportingD.is,tosupport4.Thepurposeofnewtechnologiesistomakelifeeasier,_...
