GMAT（VERBAL）语法改错模拟试卷4（共220题）

GMAT（VERBAL）语法改错模拟试卷4（共9套）（共220题）GMAT（VERBAL）语法改错模拟试卷第1套一、逻辑推理(本题共25题，每题1.0分，共25分。)1、Europe’stravelindustryissufferingasaresultofasluggisheconomy,astretchofbadweather,aswellasthechillingeffectsofterroristactivitythatispersistent.A、aswellasthechillingeffectsofterroristactivitythatispersistentB、andthechillingeffectofterroristactivitythatispersistentC、butpersistentterroristactivityhashadachillingeffecttooD、andthechillingeffectsofpersistentterroristactivityE、aswellasthechillingeffectsofterroristactivitythatpersists标准答案：D知识点解析：A、B、E中用that从句来限定terroristsactivity不如用persistentterroristactivity这样的名词短语简洁。C中but改变了句意，同时but之后用句子与前面的名词短语不能形成平行结构。D用and代替了aswellas，因为用一个词代替三个词同样也是一种简洁的表达方式。2、Ifindustrialpollutioncontinuestodepletetheozonelayer,theresultingincreaseinultravioletradiationwillendangerhumanhealth,causingariseintheincidenceofskincancerandeyedisease,andperhapseventhreateningglobalecologicalsystems.A、andperhapseventhreateningB、andmayeventhreatenC、andevenapossiblethreattoD、aswellaspossiblythreateningE、aswellasapossiblethreatto标准答案：B知识点解析：本句考核辨别并列结构的能力，即划线部分是与前面的哪一部分并列：是与前面的causing分词短词并列(如A、D)，是与谓语动词willendanger并列(如B)，还是与causing的宾语arise并列(如C、E)。假设A、D的并列方式是对的，则表明“危及人类健康(主句谓语)”这一动作会带来两个伴随结果：(1)导致皮肤癌及眼病的增加；(2)威胁全球生态环境。显然，第二个结果及主句这个行为是风马牛互不相及的事，句意上理解不通；采用类似办法，也可推断出第三种并列方式是错误的，从而第二种并列，即B选项正确，说明“紫外线的增加不仅会危及人类健康同时还会威胁全球的生态环境”。3、Thegrowingdemandforhousing,trafficcongestion,andlongercommutingtripshasallbuteliminatedthecostadvantageofowningahouseinmanyruralcommunities.A、Thegrowingdemandforhousing,trafficcongestion,andlongercommutingtripshasB、Trafficcongestion,thegrowingdemandforhousing,andlongercommutingtripshasC、Longercommutingtrips,trafficcongestion,andthegrowingdemandforhousinghasD、Trafficcongestion,longercommutingtrips,andthegrowingdemandforhousinghaveE、Thegrowingdemandforhousing,aswellastrafficcongestionandlongercommutingtrips,have标准答案：D知识点解析：B、C中主谓不一致。E同理，aswellas作为插入成分，不影响主语的单、复数属性。A、B错是由于并列成分中的一个部分——thedemandforhousing中有一个介词for，可能会产生歧义，误认为不仅housing，而且还包括trafficcongestion，longercommutingtrips均为for的宾语，这样就明显改变了句意。而D将并列中的不同部分的顺序做了调整，避免了此误会(请体会平行结构的第三个特征：意思上不能引起争议)。值得一提的是，平行结构的表达中有这样一条原则：即平行部分的次序按其长短排列，最短的、词最少的放在最前面；最长的、词最多的部分放在并列部分的结尾处。D选项也同时满足了此要求。本句中allbut可译为：几乎，差不多。(可对照：E7—12中：omens，messagesrecededatseancesandsignsfromheaven)4、ArecentNewYorkTimeseditorialcriticizedthecity’selectionboardfor,firstofall,failingtoreplaceoutmodedvotingmachinespronetobreakdowns,andsecondarily,fortheirfailuretoinvestigateallegationsofcorruptioninvolvingboardmembers.A、secondarily,fortheirfailuretoB、secondly,fortheirfailuretoC、secondly,thattheirfailedanddidnotD、second,thattheyfailedtoE、second,forfailingto标准答案：E知识点解析：由未划线部分的for,firstofall，failingto，决定了划线部分for之后应为failing，而不是其他表达。此要求，仅E符合。同时需提出的是：secondly或者firstly,thirdly这种用法已很少见了，而代之以first，second，third作副词放在句首。此点，在写作时尤其需注意。5、In1978anationalstudyfoundthatnotonlyhadmanycontractorslicensedbyaself-policingprivateguildfailedtopassqualifyingexams,theyinadditionfalsifiedtheirreferences.A、theyinadditionfalsifiedtheirreferencesB、theyhadtheirreferencesfalsifiedinadditionC、buttheyhadalsofalsifiedtheirreferencesD、theyhadalsofalsifiedtheirreferenceE、buttheirreferenceswerefalsifiedaswell标准答案：C知识点解析：本句是notonly…butalso的并列用法，仅C、E符合此结构，但E中用了被动语态，D用主动语态，因而排除E。6、Ignoringtheadmonitionsofhisstaff,thechieffinancialofficeracceptedtheadviceoftheconsultingcompanybecausehebelievedthatthestandardizedaccountingprocedureswouldprovenotonlyinexpensivebutreliableindicatorsofeconomicperformance.A、hebelievedthatthestandardizedaccountingprocedureswouldprovenotonlyinexpensivebutB、thestandardizedaccountingprocedureswillprovebothinexpensiveandalsoC、hebelievedthestandardizedaccountingprocedureswouldprovethemselvestobebothinexpensiveandD、hebelievedthatthestandardizedaccountingprocedureswouldprovetobebothinexpensiveandE、standardizedaccountingprocedureswillprovehisbeliefthattheyarebothinexpensiveand标准答案：D知识点解析：B中有两个缺陷：(1)willprove所表示的一般将来时与主句的一般过去时是不对应的；(2)both与andalso的搭配是不正确的。c中也有两令毛病：(1)宾语从句省了标志词that；(2)themselves多余(对照看12-55)。A、D比较：A有一个缺陷，即在notonlyA1butalsoA2结构中，要求两个并列成分不能存在省略，即不能在A1中(或A2中)省略了与A2中(或A1中)相同的部分，如本例A项，notonlyinexpensive之后就省去了indicatorsofeconomicperformance，从而导致了A1与A2在形式上不一致。而bothA1andA2结构中，就允许A1和A2共用同一部分，而该部分可在A1中，也可在A2中，如本例的正确选项D(共用部分为indicatorsofeconomicperformance)。7、Althoughitwasexpectedthatworkersunderfortywouldshowhostilitytotheplan,theresearchreportindicatesthatbothyoungerandtheolderpeopleapproveofgovernmentalappropriationsforSocialSecurity.A、youngerandtheolderpeopleB、youngerpeopleandtheolderC、theyoungerandtheolderD、youngerandolderpeopleE、peoplewhoareyoungerandthosewhoareolder标准答案：D知识点解析：A、B中both之后无the，而and之后有the，形式上不对称。C、D、E从句意上都对，但D最简洁。可能考生以前常见的都是用the+adj．代表某一类人，如：thepoor或者therich表穷人或者富人。但在GMAT中，不用the同样可表某一类人，如E7—34、E9-56、8-5中的poorandrich，因而选D。8、Dr.Sayre’slecturerecountedseverallittle-knownepisodeintherelationsbetweennationsthatillustrateswhatiswrongwithalliancesandtreatisesthatdonothavepopularsupport.A、relationsbetweennationsthatillustratesB、relationofonenationwithanotherthatillustratesC、relationsbetweennationsthatillustrateD、relationofonenationwithanotherandillustrateE、relationsofnationsthatillustrates标准答案：B知识点解析：A、C中用betweennations不符合between仅用于两者之间的用法。D中andillustrate的表达使得illustrate找不到平行对象。E中illustrates用第三人称单数形式与其先行词relations的复数形式不对应，B中that的先行词是relation。9、Intar,theoldestHispanictheatercompanyinNewYork,hasmovedawayfromtheSpanishclassicsandnowitdrawsontheworksbothofcontemporaryHispanicauthorswholiveabroadandofthoseintheUnitedStates.A、nowitdrawsontheworksbothofcontemporaryHispanicauthorswholiveabroadandofthoseB、nowdrawsontheworksofcontemporaryHispanicauthors,boththosewholiveabroadandthosewholiveC、itdrawsontheworksofcontemporaryHispanicauthors,boththoselivingabroadandwholiveD、drawsnowontheworksbothofcontemporaryHispanicauthorslivingabroadandwhoarelivingE、drawsontheworksnowofbothcontemporaryHispanicauthorslivingabroadandthose标准答案：B知识点解析：由于该句属于同一动作执行者Intar的两个并列动作的平行结构，因而A、C中的it(指Intar)均可省去。比较B、D、E，D、E中both后的对象与and后的对象不具备可比性，同时E中now的位置不对。10、Thepresidentsoftheblockassociationtriedtoconvinceherneighborstheyshouldjoinforcestopreventcrimeintheneighborhoodratherthancontinuingtobevictimized.A、theyshouldjoinforcestopreventcrimeintheneighborhoodratherthancontinuingtobevictimizedB、thattheyshouldjoinforcestopreventcrimeintheneighborhoodratherthancontinuetobevictimizedC、aboutjoiningforcestopreventcrimetheneighborhoodinsteadofcontinuingtobevictimizedD、forthejoiningofforcestopreventcrimeintheneighborhoodratherthancontinuetobevictimizedE、tojoinforcestopreventcrimeintheneighborhoodratherthancontinuingtobevictimized标准答案：B知识点解析：由ratherthan之后跟动词原形，可排除A，E。由insteadof之后只跟名词或动名词的原则，排除C。D中convincesb．forsth．的用法不符合表达习惯。而B的表达是正确的。11、Afireinanenclosedspaceburnswiththeaidofreflectedradiationthatpreheatsthefuel,makingignitionmucheasierandflamesspreadingmorequickly.A、flamesspreadingB、flamespreadsC、flamesarecausedtospreadD、causingflamestospreadE、causingspreadingoftheflames标准答案：D知识点解析：由划线部分之前的mucheasierand及划线之后的morequickly可断定，划线部分是与前面的makingignition构成平行结构，因而排除A、B、C，它们在形式上不对称；另外cause之后一般跟动词不定式，因而选D而排除E。12、Inmetalworkoneadvantageofadhesive-bondingoverspot-weldingisthatthecontact,andhencethebonding,iseffectedcontinuouslyoverabroadsurfaceinsteadofaseriesofregularlyspacedpointswithnobondinginbetween.A、insteadofB、asopposedtoC、incontrastwithD、ratherthanatE、asagainstbeingat标准答案：D知识点解析：尽管A、B、C这些词组均可用于表示前后对比的意思，但它们之中的最后一个词都是介词(of,to，with)决定了它们之后只能跟名词。而在此之前是介词短词overabroadsurface，那么划线之后也必须是介词短语。这两个要求存在矛盾，因而此功能(表2对比)只能由ratherthan来充当。D中补出介词at，符合平行原则。E中asagainst同样也有“对比”之意，但其之后是名词形式beingat短语，也不符合平行要求。13、Arecentstudyhasfoundthatwithinthepastfewyears,manydoctorshadelectedearlyretirementratherthanfacethethreatsoflawsuitsandtherisingcostsofmalpracticeinsurance.A、hadelectedearlyretirementratherthanfaceB、hadelectedearlyretirementinsteadoffacingC、haveelectedretiringearlyinsteadoffacingD、haveelectedtoretireearlyratherthanfacingE、haveelectedtoretireearlyratherthanface标准答案：E知识点解析：本句同样是要明确哪两个之间存在并列关系，由题意可知，本句是elect的两个宾语之间的并列，即选择早退休而不是选择面对法律诉讼的威胁和不断增长的误诊保险费。由此，排除形式上不能形成平行结构的A、B，elect之后一般跟动词不定式，而不跟动名词，排除C。D中ratherthan之后未用动词原形。14、Geologistsbelievethatthewarningsignsforamajorearthquakemayincludesuddenfluctuationsinlocalseismicactivity,tiltingandotherdeformationsoftheEarth’scrusts,changingthemeasuredstrainacrossafaultzone,andvaryingtheelectricalpropertiesofundergroundrocks.A、changingthemeasuredstrainacrossafaultzone,andvaryingB、changingmeasurementsofthestrainacrossafaultzone,andvaryingC、changingthestrainasmeasuredacrossafaultzone,andvariationsofD、changesinthemeasuredstrainacrossafaultzone,andvariationsinE、changesinmeasurementsofthestrainacrossafaultzone,andvariationsamong标准答案：D知识点解析：A、B、C中动名词changing短语与前面未划线的名词词组在形式上不能形成平行结构；比较D、E，E中有两个毛病：(1)D中change短语中，in短语的核心词为strain，而E把核心词改为measurement，句意随之改变；(2)在某方面的变异用variationinsth．而不用介词among；正如本句“在某方面的变化”用changeinstrain一样。15、Someanalystscontendthattruecapitalismexistsonlywhentheownershipofbothpropertyandthemeansofproductionisregardedasaninalienablerightofindividual’s,anditisnotalicensegrantedbygovernmentandrevocableatwhim.A、isregardedasaninalienablerightofanindividual’s,anditisnotB、areregardedasindividuals’inalienablerights,andthatitnotbeC、isregardedasanindividual’sinalienableright,notasD、areregardedasanindividual’sinalienablerights,notwhentheyareE、isregardedastheinalienablerightsofanindividual,notwhenitis标准答案：C知识点解析：本句是issth…notsth．的平行结构，D中they指代有明显错误(只能指代analysts，篡改了句意)。B中的are与单数主语不一致。A中有两个毛病：(1)individual’s中的’s是多余的；(2)anditis也多余，因为主谓语前后相同，完全可省。比较C、E，E中notwhenitis与前面的when从句形成并列关系；itis之后省了regardedas。这样表达的缺陷在于未能突出asrights和notasalicense是同一条件的两个方面，也未能突出only的强调作用，使句意发生了变化.C句中asrights与notasalicense是并列的主语补语，并作为when从句的一部分，only的强调含义也就很清楚地被表现出来，并且表达得很简洁。16、FromthetimeofitsdefeatbytheGermansin1940untilitsliberationin1944,Francewasabitteranddividedcountry;akindofcivilwarragedintheVichygovernmentbetweenthosewhowantedtocollaboratewiththeNaziswiththosewhoopposedthem.A、betweenthosewhowantedtocollaboratewiththeNaziswiththoseopposedB、betweenthosewhowantedtocollaboratewiththeNazisandthosewhoopposedC、betweenthosewantingtocollaboratewiththeNaziswiththoseopposingD、amongthosewhowantedtocollaboratewiththeNazisandthosewhoopposedE、amongthosewantingtocollaboratewiththeNaziswiththoseopposing标准答案：B知识点解析：本句是between…and的用法，仅B符合此要求(本句中有一个from…until句型)。17、ItisnotlikelythatthecompetitiveimbalancethatnowexistsbetweenJapanwithallmajorindustrialnationswillberedressedduringtheforeseeablefuture.A、withallmajorindustrialnationswillberedressedduringB、withallothermajorindustrialnationswillberedressedwithinC、withallothermajorindustrialnationswillberedressedduringD、andallmajorindustrialnationswillberedressedduringE、andallothermajorindustrialnationswillberedressedwithin标准答案：E知识点解析：本句是between…and结构，因而可排除A、B、C。比较D、E，D中有两个缺陷：(1)D中all之后未补出other，也就是未把自身(Japan)排除，逻辑上有问题；(2)during一般不与将来的时间段连用，E中用within连接将来的时段就合乎习惯。18、Themostfavorablelocationsforthegrowthofglaciers,ratherthanbeingthecold,drypolarregions,wouldbeinsteadthecool,moistmiddlelatitudes,wherethereisabundantprecipitationandwhereitiscoldenoughtoallowsomesnowtoaccumulateyearbyyear.A、glaciers,ratherthanbeingthecold,drypolarregions,wouldbeinsteadthecool,moistmiddlelatitudesB、glaciersarenotthecold,drypolarregionsbutthecool,moistmiddlelatitudesC、glaciersarethecool,moistmiddlelatitudesratherthanthecold,drypolarregionsD、glaciers,insteadofbeingthecold,drypolarregions,wouldbethecool,moistmiddlelatitudesE、glaciersare,insteadofthecold,drypolarregions,ratherthecool,moistmiddlelatitudes标准答案：B知识点解析：C中修饰对象错位，本应修饰thecool，moistmiddlelatitudes的两个where从句变为对thecold，drypolarregions的修饰。B中用not…but结构清楚地表明了“不是…而是”的句意。A、E中：insteadof与rather(than)出现在同一句中属于语义重复。D中being多余，且结构不如B简洁。19、Inthe1950’sastronomersweredividedbetweenthosewhobelievedtheuniversebeganinacosmicexplosion(the"bigbang")withthosewhofavoredthemodelofaneternalandinfinitesteady-stateuniverse.A、universebeganinacosmicexplosion(the"bigbang")withB、universebeganwithacosmicexplosion(the"bigbang")andC、universehadabeginninginacosmicexplosion(the"bigbang")orD、universe’sbeginningwasacosmicexplosion(the"bigbang")orE、universe’sbeginningwasacosmicexplosion(the"bigbang")against标准答案：B知识点解析：本句是between…and的用法，除B外，其余选项搭配都不当。20、TheenergysourceonVoyager2isnotanuclearreactor,inwhichatomsareactivelybrokenapart;ratherakindofnuclearbatterythatusesnaturalradioactivedecaytoproducepower.A、apart;ratherB、apart,butratherC、apart,butratherthatofD、apart,butthatofE、apart;itisthatof标准答案：B知识点解析：C、D、E中thatof属多余，它们的加入会导致句意无法理解。因为that指代anuclearreactor，把其代入C、D、E，就成为anuclearreactorofakindofnuclearbattery，不知所云。且E中省去but，用分号连接，弱化了转折语气。Arather单独出现只能作为形容词，与本句句意不符，要表示转折需要与than或but连用才正确。21、From1982to1987salesofnewsmallboatsincreasedbetweenfiveandtenpercentannually.A、From1982to1987salesofnewsmallboatsincreasedbetweenfiveandtenpercentannuallyB、Fivetotenpercentistheannualincreaseinsalesofnewsmallboatsintheyears1982to1987C、Salesofnewsmallboatshaveincreasedannuallyfiveandtenpercentintheyears1982to1987D、Annuallyanincreaseoffivetotenpercenthasoccurredbetween1982to1987inthesalesofnewsmallboatsE、Occurringfrom1982to1987wasanannualincreaseoffiveandtenpercentinthesalesofnewsmallboats标准答案：A知识点解析：B、C中intheyear1982to1987的表达模糊，不如用from1982to1987清晰简洁。同时B、C、D、E中的fivetotenpercent或者fiveandtenpercent都让人产生疑惑：为什么年增长率是5％～10％这样一个范围而非一具体数值?为什么年增长率既是5％又是10％(fiveandtenpercent)?A中用betweenfiveandtenpercent准确表达句意，即：在1982年到1987年之间，这种小船的年销售增长率在5％到10％之间波动。22、Despiteitsattractiveness,investingabroadcanstillposebigrisks,rangingfromthepotentialforpoliticalinstabilityinsomecountriestotheshortageofregulationstoprotectinvestorsandaseriouslackofinformationaboutinvestmentsinothers.A、totheshortageofregulationstoprotectinvestorsandaseriouslackofinformationaboutinvestmentsinothersB、totheshortageofregulationstoprotectinvestorsandinothersaseriouslackofinformationaboutinvestmentsC、andtheshortageofregulationstoprotectinvestorsandaseriouslackofinformationaboutinvestmentsinothersD、andtheshortageofregulationstoprotectinvestorstoaseriouslackofinformationaboutinvestmentsinothersE、totheshortageofregulationstoprotectinvestorsinothersandaseriouslackofinformationaboutinvestments.标准答案：A知识点解析：未划线的rangingfrom提示本句是from…to的表范围结构，本句中除C外，其他4个选项都用了此结构。一般来说，from…to…结构只并列2个内容，但此处却出现3个方面：thepotential，theshortage，alack。因而其中有2个应用and连接组成大并列结构中的一个部分，而另一个则成为大并列结构中的另一部分。那么究竟谁跟谁由and连接成为一个并列的子项呢?这并非随意组合，正如在前面例题讲到的，意思相近的或密切相关的才能组合在一起。由本句句意，theshortage和alack句意相近，适合并列成为一个from…to…子项。因此，排除D。A、B、E的根本差异在于对inothers的位置考虑。在本句中，inothers就是指inothercountries，与前面的insomecountries对应。B中将inothers放在alack之前，与前面的insomecountries放在名词词组末尾在形式上不对应；E的确将inothers放在theshortage名词词组之后，但这样就会导致一种误解，即inothers仅修饰theshortage，而不修饰后面的alack，而句意要求inothers不仅要修饰theshortage，还要修饰alack。而A中的表达则把inothers放在并列之末，表明investors之后省略了inothers，表明了句意。23、Scientificinterestinprovidingsuitablehabitatsforbottom-dwellinganimalssuchasriverclamsarisesnotbecausetheyareimportantsourcesofhumanfoodbutfromtheirroleasanintegrallinkintheaquaticfeedchain.A、notbecausetheyareimportantsourcesofhumanfoodB、althoughtheyarenotanimportantsourcesofhumanfoodC、notinthattheyareimportantashumansourcesoffoodD、notfromtheirimportanceasasourceofhumanfoodE、notfrombeingimportantsourcesoffoodforhumanbeings标准答案：D知识点解析：本句是not…but结构，由but之后的fromtheirrole决定了与其形式上对应而又符合句意的仅有D选项。24、Asitbecomesmorefrequenttohavespouseswhobothworkoutsidethehome,companiesarebeginningtohelpinfindingnewemploymentforthespousesoftransferredemployees.A、itbecomesmorefrequenttohavespouseswhobothworkoutsidethehomeB、itbecomesmorefrequenttohavecouplesbothworkingoutsidethehomeC、itbecomesmorecommonthatbothhusbandandwifeshouldbeworkingoutsidethehomeD、itbecomesmorecommonforbothhusbandandwifetoworkoutsidethehomeE、couplesinwhichbothofthespousesworkingoutsidethehomebecomemorecommon标准答案：D知识点解析：根据结构，D符合这个结构，只不过用become替换了is。A、B中有两个错误：frequent在这里属使用不当，而havespouses和句子要表达的意思不一致，且会造成一种歧义：“公司使这些夫妇在外工作”，C中的shouldbeworking是没有任何依据的。E中的couplesinwhichbothofthespousesworkingoutside的表达过于笨拙，并不符合习惯。25、Itmaysomedaybeworthwhiletotrytorecoveruraniumfromseawater,butatpresentthisprocessisprohibitivelyexpensive.A、ItmaysomedaybeworthwhiletotrytorecoveruraniumfromseawaterB、Someday,itmaybeworthwhiletotryandrecoveruraniumfromseawaterC、TryingtorecoveruraniumfromseawatermaysomedaybeworthwhileD、TotryfortherecoveryofuraniumoutofseawatermaysomedaybeworthwhileE、Recoveringuraniumfromseawatermaybeworthwhiletotrytodosomeday标准答案：A知识点解析：根据题意套此结构，选A。B中的totryandrecover的表达是不对的，必须是trytodosth．或trydoingsth．；D中的tryfor指“谋求，争取”，改变原句意思。E中trytodo与句首的recovering属语义重复现象，没有A简洁。C用动名词作主语，按理说是可以成立的，但动名词与动词不定式作主语有唯一的细微差别：即动名词一般指通常性的、习惯性的动作，而动词不定式指某一特定动作(试比较：sellinginsuranceisaprettilyboringjob和Itwasdifficulttosellmycar．)，而本句中用了someday，表明是某一特定动作，因而选A排除C。GMAT（VERBAL）语法改错模拟试卷第2套一、逻辑推理(本题共25题，每题1.0分，共25分。)1、EventhoughBelaBartok’smusichasprovedlesspopularthanIgorStravinsky’sandlessinfluentialthanArnoldSchonberg’s,itisnolessimportant.A、Stravinsky’sandlessinfluentialthanArnoldSchonberg’s,itB、Stravinsky’sandlessinfluentialthanArnoldSchonberg’s,heC、Stravinsky’sisandlessinfluentialthanArnoldSchonberg’sis,itD、StravinskyandnotasinfluentialasArnoldSchonberg,heE、StravinskyandnotasinfluentialasArnoldSchonberg,it标准答案：A知识点解析：B、D中he的出现是不对的，让步从句在讨论作品，主句却变为了讨论人，逻辑关系不明确，(让步从句讨论人，主句却变成讨论作品)。E中成了“作品与人比较”，不具可比性；C中补出的谓语动词is是没有根据的，因为than之前是完成时态，注意此题中A项并未补出than之后的谓语动词是因为此句比较对象清楚、明确，省略后不会造成歧义。2、InhiseagernesstofindacityworthyofPriam,theGermanarchaeologistSchliemanncutthroughTroyanduncoveredacivilizationathousandyearsolderaswasthecityHomer’sheroesknew.A、olderaswasthecityHomer’sheroesknewB、moreancientthanthecityknowntoHomer’sheroesC、olderthanwasthecityknowntoHomer’sheroesD、moreancientofacitythanHomer’sheroesknewE、olderofacitythanwastheoneknowntoHomer’sheroes标准答案：B知识点解析：A中older和as属搭配不当，D、E中共同的错误有三个：(1)older(moreancient)之后的of属多余；(2)acity是泛指，本处应特指，指“Troy”；(3)than位置不对；B与C比较，有两个优点：(1)ancient指“古老”，在此处比old的含义准确；(2)划线部分和前面的athousandyears共同组成一个后置名词词组修饰acivilization。因此C中补出was，出现句子结构是不必要的；而B避免了此缺陷，且比较也很明确。3、Severalstudieshavefoundthatthecoronarypatientswhoexercisemostactivelyhavehalforlessthanhalfthechanceofdyingofaheartattackasthosewhoaresedentary.A、havehalforlessthanhalfthechanceofdyingofaheartattackasthosewhoaresedentaryB、havehalfthechance,orless,ofdyingofaheartattackthanthosewhoaresedentarydoC、havehalfthechancethattheywilldieofaheartattack,orless,thanthosewhoaresedentarydoD、areatleastfiftypercentlesslikelytodieofaheartattackasthosewhoaresedentaryE、areatleastfiftypercentlesslikelythanthosewhoaresedentarytodieofaheartattack标准答案：E知识点解析：A中lessthan与as不能搭配；B、C中than之前无比较级出现(lessthan是与之相并列的部分)；D中belikelyas同样不能搭配；E中的atleast就消除了“同级和比较级共用一个than的误解”。todieofaheartattack是修饰likely，因为该短语较长，所以后置，同时E的belikelytodosth．符合习惯用语的表达。类似的还有becommitted／inclinedtodosth．(倾向于做某事)。4、OfallthepossibledisastersthatthreatenAmericanagriculture,thepossibilityofanadversechangeinclimateismaybethemoredifficultforanalysis.A、ismaybethemoredifficultforanalysisB、isprobablythemostdifficulttoanalyzeC、ismaybethemostdifficultforanalysisD、isprobablythemoredifficulttoanalyzeE、is,itmaybe,theanalysisthatismostdifficult标准答案：B知识点解析：A、D中出现比较级moredifficult却未出现than和比较对象。同时根据未划线部分的ofallthepossibledisasters可推断此处应用最高级形式。E中句子复杂且无必要。difficult之后一般用动词不定式修饰，而不用for介词短语修饰，应排除C、E。5、Whatwasasremarkableasthedevelopmentofthecompactdischasbeentheuseofthenewtechnologytorevitalize,inbettersoundthanwaseverbeforepossible,someoftheclassicrecordedperformancesofthepre-LPera.A、WhatwasasremarkableasthedevelopmentofthecompactdiscB、ThethingthatwasasremarkableasdevelopingthecompactdiscC、NolessremarkablethanthedevelopmentofthecompactdiscD、DevelopingthecompactdischasbeennonethelessremarkablethanE、Developmentofthecompactdischasbeennolessremarkableas标准答案：C知识点解析：D中的nonetheless意为“尽管…仍然”或“并不因为…而不…”，在本句使用不恰当；E中的Noless…as不搭配；B中thethingthat实际上就等于what，不如A简洁；同时，B、D中的developing是不恰当的；A、C之间在意思上无太多差异，选C因为它更符合习惯用法。6、ThenumberofundergraduatedegreesinengineeringawardedbycollegesanduniversitiesintheUnitedStatesincreasedbymorethantwicefrom1978to1985.A、increasedbymorethantwiceB、increasedmorethantwotimesC、morethandoubledD、wasmorethandoubledE、hadmorethandoubled标准答案：C知识点解析：最简洁；D、E时态不对。7、SaltdepositsandmoisturethreatentodestroytheMohenjo-KaroexcavationinPakistan,thesiteofanancientcivilizationthatflourishedatthesametimeasthecivilizationsintheNiledeltaandtherivervalleysoft
