，表示地点。19、RecentlyIboughtanancientvase，________wasveryreasonable．A、whichpriceB、thepriceofwhichC、itspriceD、thepriceofthat标准答案：B知识点解析：考查非限制性定语从句。从句的主语与先行词的关系，即price和vase是所有格关系，介词后的关系代词不可用that。故选B。20、Therewasnothingthattheycoulddo________．A、butwaitB、exceptwaitingC、onlytowaitD、unlesstheywait标准答案：A知识点解析：考查固定搭配。nothing…but为固定结构，意为“只有，除了……之外别无可做”。此外，后边的wait与do并列，也应该用动词原形。故选A。三、完型填空(本题共10题，每题1.0分，共10分。)Myhusbandusedtoworkinabankbutduringthecrisishe【C1】______hisjob．Theeconomywasn’tgoodandhehadn’tmany【C2】______togetanotherbankjob．Wewerehopingandprayingthathewouldbeofferedaposition．Hegotajobanditbroughtusafeelingofpride．Wewereableto【C3】______ourmortgageandbuyourgroceries；butmoneywasstillvery【C4】______，sohefoundanotherjobmakingdeliveriesfromMondaytoThursday．HehasbeenworkingsohardthatIwantedtomakeitanextra【C5】______Christmasthisyear．Iwantedourhousetobefilledwith【C6】______—Ididn’twantanybodytobealonethisyear．IfinallygotroundtogettingtheChristmastreeoutyesterdayand1workedalldaytomakethehouselook【C7】______．Whenmyhusbandcamehomeat8p．m．helooked【C8】______．Seeingthehousehebrokeupthebiggestsmile，grabbedmeandgavemeahugehug．Thenheapologizedfornotbeingabletohelpme．Hesaidheknewitwashardonmebecausehedidn’tget【C9】______andhewasgratefulthatIhadnotcomplained．Hewasapologizingforworkingsohardtofeedusandkeepa【C10】______overourheads!Hewasdoingtwojobsthatmademuchlessthanhispreviousjobandcominghomeexhausted．IhadnowordstotellhimhowmuchIlovedhimandhowproudIwasofhimandthathewassuchagreathusbandandfatherandproviderforus．Withthisamountofloveinourhousewewillalwayshavemorethan“enough”．21、【C1】A、resignedB、escapedC、improvedD、lost标准答案：D知识点解析：由but可知这里表示转折，又由“duringthecrisis”可知，由于经济危机，她的丈夫失去了工作，lostjob表示“失去工作”。22、【C2】A、excusesB、optionsC、plansD、disadvantages标准答案：B知识点解析：由“Theeconomywasn’tgood”可知，要找到一份新的工作并不容易，即她的丈夫没有很多选择再找到一个银行的工作。23、【C3】A、payB、spendC、expendD、enjoy标准答案：A知识点解析：paymortgage表示“还贷款”，其余三项与mortgage不搭配。24、【C4】A、toughB、comfortableC、tightD、dirty标准答案：C知识点解析：虽然她丈夫找到了工作，但是钱仍是很紧张的。tight表示“拮据的，缺钱的”。25、【C5】A、naturalB、colorfulC、regularlyD、special标准答案：D知识点解析：由语境可知，妻子因为丈夫工作很劳累，希望让他过一个特别的圣诞节，special表示“特别的”。26、【C6】A、energyB、sunshineC、companyD、excitement标准答案：D知识点解析：因为前面说是一个很特别的圣诞节，所以要让房子充满惊喜，故选D。excitement表示“令人兴奋的事物”；energy表示“能量；活力”；sunshine表示“阳光，愉快”；company表示“陪同”。27、【C7】A、decoratedB、neatC、splendidD、festive标准答案：D知识点解析：decorated表示“装饰的”；neat表示“整洁的”；splendid表示“辉煌的”；festive表示“喜庆的，欢乐的”。因为是过圣诞节，所以应该是“喜庆的，欢乐的”。28、【C8】A、exhaustedB、livelyC、humorousD、childish标准答案：A知识点解析：exhausted表示“疲惫的”；lively表示“生动的”；humorous表示“幽默的”；childish表示“孩子气的”。丈夫工作了一天，直到晚上八点才回来，可想他一定是疲惫的。29、【C9】A、inB、offC、overD、around标准答案：A知识点解析：getin表示“参与，到达，收获”；getoff表示“起飞，下车”；getover表示“越过，解决难题”；getaround表示“逃避，说服”。根据语境，应选A，表示“参与”。30、【C10】A、secretB、smileC、roofD、faith标准答案：C知识点解析：keeparoofoverourheads表示“使我们有栖息之地”，符合文意。四、阅读理解(本题共15题，每题1.0分，共15分。)Eatmorehealthily．Exercisetwiceaweek．Readmorebooks．Loseweight．Wemakethesameresolutionseveryyear，butmostofusfail，andquitafteronlyafewdaysor，atbest，weeks．Eventhemostsuccessfulamonguscrashwhenitcomestopersonalchange．Forexample，PresidentBarackObamastruggleswithhissmokinghabit．Sowhyischangesochallenging?Arewewiredinawaythatkeepsusfrommakingchanges?Anddoweneedthesupportofotherstoreachourgoal，orcanwedoitalone?Professionalswhohelppeoplemakechangeintheirlivessuggestthatthechangeisdeterminednotbyone’smind．Beginningwithsmallgoalsorstepsusuallyleadstoabiggerpay．oflater，theysay．Andtryingtomakeachangeiseasierwithsupportfromagroupoffriends，family，orco-workerswithsharedgoals．“Peoplearemorelikelytomakepositivechangesintheirlivesnotonlywhentheirfriendsdo，butwhentheirfriendsoffriendsdo，andwhentheirfriendsoffriendsoffriendsdo．”saidNicholasChristakis，aprofessorofmedicalsociologyatHarvardUniversity．JohnnyAugustinunderstandsthatwell．Hisresolutionfor2009wastoreduce30poundsfromhis237-poundframe．Butthechangedidn’tcomeeasy．Hesaid，“I’mahugeprocrastinator．There’sdesire，butIjustkeptputtingitoff．Ididn’tgettoituntilthesummer．”However．Augustingotinspiredwhenhesawhiselderbrotherworkingout．NowAugustinweighs190pounds．Havingapositiveattitudeisoneofthekeystomakingasuccessfulchange．accordingtoJudyZerafa，authorofseveralbooksbasedonhowpeoplecanimprovetheirlives．Sheemphasizestheimportanceofbelievinginyourself-andhavingpositivehabits，acreativeimagination，andpersistence-tomakechangehappen．31、Thetext1smainlyabout_______．A、thereasonswhymakingachangeissohardB、thedifficultieswehaveinmakingachangeC、thewaysofmakingachangeinourlifeD、theattitudestowardsmakingachange标准答案：C知识点解析：本文主要讲述了专家学者们对人们如何进行改变的建议。故C项最符合题意。32、AccordingtoNicholasChristakis，______．A、friendshipplaysanimportantroleinourdailylivesB、peoplearebetterabletomakechangeswheninspiredbyothersC、friendscaneasilychangeourmindsaboutsomethingD、friends’supportplaysabiggerroleinone’ssuccessthanhismind标准答案：B知识点解析：根据第四段的第一句可知，NicholasChristakis认为当人们的朋友或朋友的朋友们发生积极的转变时，他们会比较倾向于积极的转变。故可推知人们在别人的鼓励下比较容易发生转变。故选B。33、Inthetext，whichofthefollowingisNOTmentionedasawaytomakeachangeinone’slife?A、Tryingtolearnfromone’sfriends．B、Settingsmallgoalsatfirst．C、Havingconfidenceandpositivehabits．D、Cha

正确。文中第二段第一句说科幻小说经常被认为是一个很新的文学形式，但是在数百年前就可以找到科幻小说，所以A项不对；根据文章第二段第一句。文中说的是“hundredsofyearsago(成百上千年前)”，不是“lessthanahundredyears”，所以B项不对；对于C项，文章第一段说现在科幻小说很流行，并没有比较科幻小说在现在还是在过去更出名。故选D。41、Thebesttitleofthepassagemayprobablybe_______．A、ScienceFictionB、ThePopularityofScienceFictionC、TheOriginofScienceFictionD、TheThemesofScienceFiction标准答案：A知识点解析：选项A最具有概括性，能概括全文所讲的内容。It’soneofourcommonbeliefsthatmiceareafraidofcats．Scientistshavelongknownthatevenifamousehasneverseenacatbefore，itisstillabletodetectchemicalsignalsreleasedfromitandrunawayinfear．Thishasalwaysbeenthoughttobesomethingthatishard-wiredintoamouse’sbrain．ButnowWendvIngram，agraduatestudentattheUniversityofCalifornia，Berkeley，haschallengedthiscommonsense．Shehasfoundawayto“cure”miceoftheirinbornfearofcatsbyinfectingthemwithaparasite，reportedthesciencejournalNature．Theparasite，calledToxoplasmagondii，mightsoundunfamiliartoyou，buttheshockingfactisthatuptoone．thirdofpeoplearoundtheworldareinfectedbyit．Thisparasitecancausedifferentdiseasesamonghumans，especiallypregnantwomen—itislinkedtoblindnessandthedeathofunbornbabies．However．theparasite’seffectsonmiceareunique．Ingramandherteammeasuredhowminereactedtoacat’surine(尿)beforeandafteritwasinfectedbytheparasite．Theynotedthatnormalmicestayedfarawayfromtheurinewhilemicethatwereinfectedwiththeparasitewalkedfreelyaroundthetestarea．Butthat，snotall．Theparasitewasfoundtobemorepowerfulthanoriginallythought-evenafterresearcherscuredthemiceoftheinfection．Theynolongerreactedwithfeartoacat’ssmell，whichcouldindicatethattheinfectionhascausedapermanentchangeinmice’sbrains.Whydoesaparasitechangeamouse’sbraininsteadofmak
