四六级托福改错题练习

五、句子的构造句子的构造重要考察四个出题方向

（一）主语的反复名词代词谓语，这个代词永远是反复的主语，永远是错的例Woodrow Wilsonhe wasan idealistwho refusedto makeanyA Bcompromisesconcerning theestablishment of theC DLeagueof Nations.分析代词不是同位语，主语反复；假如是下面这样的主语，那么便是主语同位语heA prolificwriter,Woodrow Wilson例Two uniquefeatures of the Arcticthey are A Blackof precipitationand permanentlyfrozen ground.C D分析选项中的和前面的主语反复B theytwo uniquefeatures

（二）谓语的反复完整的句子背面又多了一种谓语，往往改为定语从句例A paragraphis aportion ofa textconsists ofA Bone ormore sentencesrelated to the sameidea.C D分析错，应改为或句中有两个无法连接的谓语B consistingof whichconsists ofo（仿佛是）看起来仿佛是）seem sound,Iook（feel,enough修饰形容词或副词时,appear,smell,taste一般放在形容词或副词例The eruptionsof Mt.背面St.Helens wereenough severetocause numerousdeaths.C D分析错，应改为是形容词，放在背面B severenough severeenough severe

九、词性的混用词汇量的掌握对词性的使用非常重要，不过假如对出题方向有更好的把握，将会弥补词汇量的局限性

（一）做表语时形容词和副词的混用做表语永远用形容词，绝对不能用副词；例Giant pandas,which inhabitrestricted areasof highA Bmountain bambooforests,are rarelytoday andCwhenthey arein captivitythey breedpoorly.D分析错，应改为为副词，不能作表语，故改为形容词（罕见的，稀are rarerarely rareo少的）

（二）加宾语时名词和动名词的混用背面加宾语当然要用动名词例Tilling meanspreparation thesoil toplant theseedsA Bandkeeping thesoil in the bestcondition tohelp thecrop growuntil itis ready3for harvesting.D分析错，应改为为名词，背面不能接宾语，改为动名词A preparingopreparation preparing后既能接宾语，又与背面的构成并列关系keeping例Langston Hughes,a prolificwriter of the192015,Awas concernedwith thedepicting theexperience ofB Curban Blackpeople in the United States.D分析错，应改为在此为动名词，作介词宾语时不加冠词注意此C depictingodepicting处还可以改为但略显累赘，由于背面尚有构造动名词，这个动名词the depictionof,of The其实就变为了名词

（三）表达时间时，状语从句连接词和近义的介词混用表达时间有两种也许，一种是状语从句，由引导，背面加句子另一种是由介词引导，如when andwhile during,背面加名词，考试中往往就运用这个特点，总是给出相反的状况例Balloon observationsfor militaryintelligenceA Bweremade whilethe AmericanCivil War.C D分析错，应改为是附属连词或并列连词，背面接句子，背面是名词短语D duringwhile时，应改为介词during例Some of the mostcelebrated publicitystunts whiletheA B Chistory ofradio wereassociated withGracie Allen.D分析错，应改为为连词，背面规定接从句，而句中显然没有从句，故根据题C inwhile意改为介词in

（四）对等连接词和近义的副词混用连接平行构造的词叫做对等连接词，不过假如出现等副词把这些构造连else,also,instead接起来行不行呢？当然不行例Mary McDowellshared JaneAddams interestin socialAworkalso wasa loyalsupporter of the Leagueof Nations.B C D分析错应改为是副词，不能连接并列的谓语动词，故改为并列连词B,ando alsoando例Paper isstrong undertension insteadcrumplesA B Ceasily underthe stressof compression.D分析错，应改为；题目意思是在拉力的作用下很强，而在压力的作用下轻易起皱；C but副词不能连接两个动词并列，的对等连接词和的使用方法是同样的instead,but and,or

（五）表达人的名词和表达事物的词混用例An editoris customarilya briefnewspaper ormagazineA Barticlethat givespersonal commentson currentevents.C D分析错，应改为的意思是“编辑”，根据题意改为名词（社论）A edtorialeditor editorial例For centuries,music haveplayed acousticalguitars,Awhich producesound fromthe vibrationofthestrings.分析错，应改为是抽象名词，意为“音乐”，不能表达复数要领显A musiciansomusic然应改为（音乐家）musicians

（六）只能用副词数量词名词；不能用形容词这里nearly two hundred students,nearly修饰的是；200twohundreddiligent students

三、谓语动词

（一）谓语动词的主谓一致

①、主谓分割原则例1To thecitizens ofthe United States,the bald eagle,AAmericas nationalbird,symbolize strengthand freedom.B分析错，应改为主语谓语用逗号分割开，主语C D C symbolizesthe为单数，谓语动词也应当用单数形式

②、与后者一致原则baldeaglenot...but,强调背面的名词，

③、与前者but not only...but also一致原则.名词复数名词，谓语+with/together with/as wellas/including+用中心词在前面，谓语动词应当与前面的名词保持一致例is,The athlete,together withhis coachand A B C分several relatives,are travelingtotheOlympic Games.D析错，与谓语动词与保持一致，改为

④、就近原则D theathlete is单数名词复数名词假如把句子变为一般疑问or,either...or,neither...nor,+or++are句，也就是把动词提到前面，那么变为因此注意一点假如是陈说句，靠背面近，用复be is数假如是疑问句，靠前面近，用单数例The structureorbehavior ofmany protozoansareA Bamazingly complexfor single-celled animals.C分析错，应改为从谓语动词是复数形式判断，主语应当为复数，连接D Aando or两个名词时动词和背面的名词保持一致，是用单数形式，因此只有改为并列连词behavior才能使主谓在数上保持一致

⑤定语从句主语就近原则and There是复数，因此从句谓语动词是复数例are fiveapples thatare red.apples Arocketburns propellantrapidly andmost rockets.A分析错,carry asupply thatlast justa fewseconds.B C D D应改为从句的逻辑主语为单数，其谓语动词应为单数形式

⑥lastso asupply the+形容词主谓——致The richare notalways happierthan thepoor.The表达一类人，应当用复数

⑦、倒装句的主谓一致改错题倒装句的主谓一致一rich般考两种状况句型.名词+名词，那么近来的a.there bethere be+名词决定其形式放在句首名词，名词其实是主语，因此和名词保b.between/among+be+be持一致例There areno knownsociety inwhich left-handed peoplepredominate.A B分析C Dthere句型由近来的名词决定其形式，当然用单数，错，改为例be societyA thereare thereis Betweenthefoothills ofthe Andesand thePacific ABOcean area drycoastal stripaveraging about30C分析倒装句，改为miles inwidth.D areis例Among thefavorite attractionsat theNational Airand.AB CSpace Museumin WashingtonD.C.are thefilm分析错，应改为主语实际上是名词，应当D presentedon thefive-story-tall screen.D films,与谓语动词保持一致

⑧、比例构造的主谓一致名词名词fifty percentof+one percentof+谓语动词的形式和比例多少没有关系，重要取决于背面的名词，例如one percentof mystudents+are fiftypercent这里要强调两个构造of mytime isspent onworking.half of=fifty可数名词不可数名词+percent most of++are mostof+is例Nearly halfoftheancient meteorcraters has been ABC foundin centraland easternCanada.分析错，应改为介词的宾语为复数名词短语，作主语的中心词当然DChave beenof half表复数，对应的谓语动词应为复数形式例Approximately fiftypercent ofthepackage utilizedA Binthe United States arefor foodsand beverages.C分析错，应改为从谓语动词用复数形式判断出主语是复数名词注意D Apackageso food用复数表达不一样种类的食品，用复数表达不一样种类的饮料，故、均没有错beverage C D二谓语动词的时态

①、重要考察时间状语例分The metalaluminum has been firstisolated earlyin thenineteenth century.ABCD析同位语，Metal,aluminum in the为明显表达过去时间的状语，因此应当用过去时态，把改为

②、nineteenth centuryhas beenwas和的区别区别一背面使用时间段，背面使用时间点区别二只能For sinceFor sinceSince用在目前完毕时态，最重要用在目前完毕时和一般过去时For I hasbeen a teacherfor threeyears.Ihasbeena teacher since

1996.这种体现可以，表达——段时间，表达过I wasateacherfor threeyears.for threeyears was去做了三年，目前不是老师了例Since1921the budgetofthe United Statesbecame ABthe primary分析错，应改responsibility ofthe president.C D A In.since一般规定主句用完毕时态，而句中谓语动词为过去式，其时间状语应与之呼应，故改为例Since InAdella PrentissHrghes servedas managerof ABCthe ClevelandOrchestrasince fifteenyears.分析错，应改为引导时间状语时，主句谓语动词为一般完毕时；主句谓语动词D Dfor since0为一般过去时要用介词；并且一段时间用而不是for for,sinceo

52.In general,prawns livedinshallow coastalwaters orin streams.A自然现象和客观事实用一般目前时态，三BC D live谓语的语态语态重要表达是积极语态还是被动语态有四组动词是改错题中常考的

①、prove Myadvice provedto be我的提议被证明是错的尽管是被证明，但习惯上用积极；.例wrong.A majorityofthe reportsreceived frompeople claimingA tohave seenthe legendaryLoch NessMonsterhave provento beBC mistakes,misconceptions,or they分析错，应改为were beingtricked.D D并列连词在此连接名词，假如把理解为并列句，不仅时态不对，语义也有问题，trickso orD故将整个句子改为名词是对的的

②、这两个词可以用作have provento beLocate,Situate积极，表达把・・・放置在・.・地方；确定・・.的位置Bats locateobstacles.蝙蝠确定障碍物的位置这两个词也可以用作被动My schoolwas辨别的积极和被动比较难，不过有一种技巧存在假如用作located nearthe river,locate locate积极,背面必须跟宾语例:一The centerof gravityofthehuman bodybehindthe hipjoint.Alocates BlocatingCto locate分析空格处显然缺谓语动词，故首先排除不能作谓语的Dis located和动词背面没有宾语，因此用作被动，表达“位于”，因此为对的选项B Colocate D

③、表达需要概念的动词等need,want,require My watch neededrepairing

④、表达人的情感的动词等Mywatchneeded tobe repaired.move,annoy,surprise,please He他令人感到感动is somoving.He isgreatly.他感到非常感动积极和被动技巧总结假如句子中有一种“过去分词moved，如坚决定它是谓语的话，前面必然有动词例+by”be TheTennessee ValleyAuthority haschartered by the AUnited StatesCongress in1933to constructdams,B powerstructures,and flood-controlworks alongCthe TennesseeRiver andits tributarystreams.分析错，应改为由信号词可知前面的谓语动词为被动D A hasbeencharteredby语态形式动词，并且前一种谓语动词下面没有划线，故改为非谓语动词形式或在它前面加consists which使之成为从句谓语动词

（三）谓语的缺乏例Most mammalsto maintaina relativelyconstant bodyABtemperature,regardless ofwhat theair temperaturemight be.C D分析错，应改为句中缺谓语动词，故去掉不定式符号使变成A maintainto maintain谓语动词

（四）主句的反复主句的反复总是考等引导的句子,不过even,instead,during,despite实际上它们无法把两个句子连接起来，由于它们都是副词或者介词，连接两个句子应当用连接词连接例Salmon spendmostoftheir adultlives insalt water,despiteA BCthey returnto theirfreshwater birthplacesto spawnand die.D分析错，应改为是介词，背面一般接名词作宾语，而在句中它背面C thoughodespite却跟着一种完整的句子，因此改为连词though o例Solar eclipsesoccur duringthe MoonsshadowA Bsweepsacross theface ofthe Earth.C D分析错，应改为或介词不能引导条件状语从句，根据题意改为附属连词B when as或whenas例Even manyearly leadersoftheUnitedStateshave providedABnames fortowns,only GeorgeWashingtonCis rememberedinthename ofa state.分析错，应改为为副词，不能引导从句，根据题意，改为引导让A Eventhough even步状语从句的考试大Even thougho

六、比较级和最高级比较级和最高级的出题非常有规则，一共有个出题方向，并且每次考试必然考两个5-比较级或最高级形式上的反复例The mosteasiest processfor mininggold ispanning,whichA involvesusing acircular dishwith asmall pocketat thebottom.BC D分析A错,应改为easiest easiest自身已是最高级，不必再用most,这是最高级形式上的反复二比较级和最高级之间的混用例The greenestand plentifulestleaves arethe leavesof grasses.ABC D分析错，应改为是多音节形容词，须在前面加构成B mostplentifulo plentifulmost最高级例The morefearsome ofall theanimals inthe WesternHemisphereA BCDis thegrizzly bear.

（三）比较词的前面一定要有比较级than分析错，应当用最高级具有介词表达的范围状语使用最高级A most,of,among,in改错题中，一般会看见前面有一种原级than例Film directorscan takefargreat libertiesin dealingwithconcepts oftime andspace thanstage directorscan.分析错，应改为根据背面有一词可以鉴定前面的形容词用比较级形式，B greaterothan注意修饰比较级far,much

（四）在以及否认的中间使用形容词原级as...as notso...as,not as...as这是不对的，应改为as sweeteras,as sweetas

①、比较级前面可以出现修饰背面的the,

（五）和比较级最高级的关系the高级加不加均thethe tallerboy例Although flieslive longestin cooltemperatures,it breedprolificallywhen temperaturesare warm,food isabundant,and humidityis moderate.分析副词的最高级加不加均可,因此对的，从从句的主语可以看出，应当theAB改为they

③、形容词的最高级作定语前面必须使用假如不作定语的话，加不加均可以例the,the Ofallthe NativeAmericans intheUnitedStates,ABCthe Navajosform largestgroup.D分析错，应改为形容词最高级前面要加定冠词D formthe largest陷阱有两种也许，1,earliest,一种也许是的最高级，最早的语言，另一种也许作名词,表达early theearliest language初期,必须和时间的名词连用,表达很早的年代，很早的时代，也就earliest time,earliest ages,是说，假如后来碰上背面加上前面不earliest times,ages,用加the例:The beliefin fairieshave existedfrom earliest times,and theliterature ofmanyA BCcountries includestales offairies andtheir relationshipto humans.D分析错,应改为主语是单数名词而不是复数名词故谓语Ahasexistedo thebelief,fairies,动词是单数形式表达表达很早的时代是对的的earliesttimes陷阱假如最高级前面有所有格的话，不用加例如2,the mybest friends例Salt LakeCity,Utahs capitaland largestcity,is industrialA BCandbanking center.D分析错，应改为为可数名词，它的修饰词前面应有不C isan industrialcenter center定冠词题目中其实是省略了Utahs largestcity,UtahSo例Faults inthe Earthscrust aremost evidentlyin sedimentaryA formations,wherethey interruptpreviously continuouslayers.BC D分析错，的表语必须用为何不加由于作表语，而不是定语A areevident,the,七平行构造改错题考的最多的一种方向便是平行构造一对等连接词一共有三类连接平行构造的词单一式and,or,but有关式both...and,not...but,either...or,neither...nor；the same...as as...as,not SO...8S,not as...assuch...as,so...that.,too...to,from...to,from...until,between...and,（可以省略），主谓，not only...but alsoalso Not only also not only...but also（可以省略）短语式also as well,aswellas（而不是）（除…之外）rather thanother than（替代）instead of考试的方式往往是搭配中有一种单词是对的，另一种单词却不对例John livedin NewYork since1960to1975,A Bbuthe isnow livingin Detroit.CD分析错，应改为“从某年到某年”要用…”这个体现法，不能用B from“from…t since...to...0例Even ashe wrotecopiously onso diverse topicsA Baseducation‘politics,and religion,Lewis Mumfordremainedactive incity andregional planning.CD分析错，改为出现往往要注意前面二分之一B suchdiversetopicsas,as,

（二）平行的内容第

一、引导词性的平行，词性的平行本质上是语法作用的平行例Photoperiodism is thefunctional orbehavioral responseof ABan organismto changesin durationof daily,seasonally,C Doryearly periodsof lightand darkness.分析错，应改为在和三个并列的词中，D seasonaldaily,seasonally yearlydaily和是形容词，是副词，故改为形容词共同修饰名词yearly seasonallyseasonal,periods,三个形容词的平行，词性平行第

二、名词单复数的平行不过假如既有可数名词，又有不可数名词，可以不平行例The mainadvertising mediainclude directmail,ABCradio,television,magazines,and newspaper.D分析错，应改为为可数名词，在没有任何前置修饰语的状D newspapersonewspaper况下一般用复数形式，并且和前面的平行，而则是不可数magazine mail,radio,television名词例The Canadianprovince ofNewfoundland hasa rockycoast,a moistureclimate,A Bandprobably thebest cod-fishing areasintheworld.CD分析海岸气候只有一种，不过钓鱼的地方可以有许多种，因此也是不可数名词和名词复数的平行；因此没有错，错改为DAhave第

三、时态的平行例The poetMarianne Moorewas initiallyassociatedwith theimagist movement,but laterdevelopsBher ownthyme patternsand verseforms.CD分析错，应改为句中前半部分谓语为过去时，与之并列的谓语也应用B developedo过去时例Because thepapaya growsreadily fromseed,——spread fromits homein Central America andnow grows throughoutthe tropics.A tobe BitC theD its分析对的答案为空格前是原因状语从句，背面紧接着是谓语动词，空格处明显缺B主句主语四个选项中只有能单独作主语注意是过去式，没有数的变化，由于这B spread一动作明显发生在过去时间和为何时态可以不平行呢？spread grows本来它在的家乡传播，目前在整个地方传播，只修饰背面的CentralAmericanowgrow例Ducks havebeen domesticatedfor manycenturies--commercially fortheir meatandeggs.A raisedB andare raisedCraised asD areraised分析对的答案为空格前是一种完整的句子，根据一种空格处如再出现谓语动词一定Bo要有连词这一原则，为惟一符合条件的选项故选B B第

四、排列位置的平行例—the surfaceof metal,but alsoweakens it.A Not only doesrust corrodeB Not onlyrust corrodesCRust,which not only corrodesDRust notonly corrodes分析对的答案为从放在动词前可知，也须置于动词前，故选、Do but alsonotonly DA中的位置放错了，使句子缺主句，故排除BNotonly C对于的使用方法有如下几种notonly,but also＞主语谓语，谓语，对的；例如上面例题中的第四个选项1notonlybut also、主谓,主谓，对的2Notonlybut also、主语谓语，谓语，错误3Notonlybutalso

八、词序的颠倒词序的颠倒一般只考一道，的状况集中于下面三个出题方向90%先说形容词

（一）例The Medalof Honoristhehighest awardmilitary forcourageA Bthatcan begiven toany individualintheUnitedStates.CD分析错，军事的荣誉是而不是单个形容词修饰名词时一B militaryaward awardmilitary,般放在被修饰词的前面

（二）副词形容词名词例Certain typesof computerswork properlyonlyA Binenvironments withcontrolled preciselytemperatures.CD分析错，应改为精确的被控制的温度为过去分词用D preciselycontrolled,controlled作形容词，修饰它的副词应放在其前面，它自己则要紧挨着被修饰的名词

（三）主语系动词，系动词表语例During the1600*s skilledshoemakers scarcewereAB Cinwhat isnow theUnitedStates.D分析错，应改为表语应当放在系动词背面所有的系动词分C werescarce为三大类第一种表达保持某种状态，（表达位于）第二种，从一种状态转变到另一种状is,remain,keep,stay,lie,exit态（）第三种，感官动become,turn,grow,get Itis gettingwarmer andwarmer词。
