paid解析：选B　她不想受到与队里别的女孩不一样的对待，指“她希望教练能把她当成正常的女孩来对待〞。因此，此处要选treated“对待〞。34．A.painsB．stressesC．injuriesD．problems解析：选D　上文已提到她有视力方面的问题。35．A.positiveB．friendlyC．flexibleD．cautious解析：选A　她在队里不希望受到优待，在比赛时不想让裁判知道她的视力有问题，这是因为她把自己当成一个正常人，妈妈对她这种乐观的生活态度感到吃惊。positive“积极的，乐观的〞，符合语境。friendly“友好的〞；flexible“灵活的〞；cautious“小心翼翼的〞，均不符合语境。36．A.defendingB．quittingC．winningD．bargaining解析：选B　文章提到Lola是个很有决心的女孩，她是永远不会放弃的。quit“退出，放弃〞。文中第五段提到“neverquit(永不放弃)〞，这也是关键提示。37．A.standardB．rangeC．viewD．goal解析：选D　到达9级是她的目标，因此此处选用goal，表示“目标〞。后面提到她想成为体操教练，这也说明了她是一个有明确目标的人。38．A.untilB．asC．whenD．before解析：选C　当她长大后，她要当一名体操教练，把她所学的传授给别的孩子。whenshegrowsup为when引导的时间状语从句。39．A.proudB．tiredC．ashamedD．confident解析：选A　beproudof“对……自豪〞；betiredof“对……厌倦〞；beashamedof“对……羞愧〞；beconfidentof“对……有信心〞。她对她所有的努力和成功当然是很自豪的。40．A.planB．adviceC．rewardD．responsibility解析：选B　“justbelieveinyourself〞是她给别人的建议，因此advice(建议，劝告)为最正确选择。Ⅳ.语法填空(共10小题；每题1.5分，总分值15分)阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。Reproductivecloningmayenableresearcherstomakecopiesofanimalswithpotentialbenefitsforthefieldofmedicineandmanyothers.Forinstance,theScottishresearcherswhoclonedDollyhavealsoclonedothersheepthathavebeengeneticallychanged__41__(produce)milkthatcontainsahumanproteinessentialforbloodclotting(凝固).Theydidthisinthehope__42__somedaythisproteinmaybeobtainedfromthemilkandgiventohumans__43__blooddoesn'tclotproperly.__44__applicationistocreateclonestobuildpopulationsofendangered,orpossiblyevenextinctspeciesofanimals.In2003,anendangeredtypeofox,calledthebanteng,wassuccessfullycloned.__45__(short)afterthat,threeAfricanwildcatswereclonedusingfrozenembryosasasourceofDNA.Someexpertsare__46__favourofcloningextinctanimals,sayingthatitcansavemanyspeciesthatwouldotherwisedisappear,whilesomeraisea(n)__47__(object),arguingthatcloningproducesapopulationofgeneticallyidenticalindividualsthatlackthegeneticvariabilitynecessaryforspeciessurvival.Somepeoplehaveevenexpressedinterestin__48__(have)theirdeceasedpetsclonedinthehopeofgettingasimilaranimaltoreplacethedeadone.Butas__49__(show)byaclonedcat,aclonemaynotturnoutexactlyliketheoriginalpetwhoseDNA__50__(use)tomaketheclone.语篇解读：本文讲述了克隆所制造出的含凝血蛋白的奶对医药学和其他领域也有所帮助，并讲了克隆的不同应用。41．toproduce　考察不定式作状语的用法。克隆其他羊的目的是制造含凝血蛋白的奶，故填toproduce。42．that　考察连接词。设空处引导同位语从句，解释说明hope的内容，且从句构造和意义均完整，故填that。43．whose　考察关系词。设空处引导限制性定语从句修饰humans，且在从句中作定语，故填whose。44．Another　考察限定词。设空处限定application，且上一段讲了克隆动物的一个应用，本段讲到的是克隆的另一个应用，故填Another。45．Shortly　考察副词。设空处作状语修饰after，故填Shortly。46．in　考察固定构造。infavourof意为“赞成，支持〞。47．objection　考察名词。设空处作宾语，表示“反对〞，故填objection。48．having　考察动词­ing形式作宾语的用法。设空处作介词in的宾语，且people与have之间是逻辑上的主谓关系，故填having。49．shown　考察过去分词作状语的用法。asshownby...意为“正如……所展示的〞。50．wasused　考察一般过去时的被动语态。DNA与use之间是被动关系，且use所表示的动作发生在过去，应用一般过去时，故填wasused。Ⅴ.短文改错(共10小题；每题1分，总分值10分)假定英语课上教师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。文中共有10处语言错误，每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。增加：在缺词处加一个漏字符号(∧)，并在其下面写出该加的词。删除：把多余的词用斜线(\划掉。修改：在错的词下划一横线，并在该词下面写出修改后的词。注意：1.每处错误及其修改均仅限一词；2．只允许修改10处，多者(从第11处起)不计分。LiMing,theengineer,wasbornonFebruary9,1960inHubei,China.AfterhegraduatedTsinghuaUniversityin1982,hemadeanimportantdecisionsinhislife.HedecidedtogototheUnitedStatesforhisfartherstudy.Afterfouryear'shardwork,hemasterednewmanagementideasandadvancingtechnologiesincomputerfield.In1989,hegothisdoctor'sdegree.In2001,hemadeoneanotherdecision.Hewasdeterminedtoturntohismotherlandandstartedacompany.However,hiswifeanddaughterhavegotusedtotheAmericanwayoflife,buttheystillstayintheUnitedStates.答案：第一句：the→an第二句：graduated后加from;decisions→decision第三句：farther→further第四句：year's→years';advancing→advanced第六句：去掉one第七句：turn→return;started→start第八句：but→soⅥ.面表达(总分值25分)假定你是新华中学的学生李华，最近你们班的同学就“成功的秘诀〞这一话题进展了讨论，以下是讨论结果。请你根据表格内容，给你的教师Mr.Smith写一封电子邮件，反映讨论结果并希望听听他对此事的看法。比例观点35%运气、天赋和成长环境等起决定作用55%目标、时间和努力更重要10%未发表意见注意：1.词数100左右；2．开头和结尾已给出，不计入总词数。DearMr.Smith，Yourstruly，LiHua参考范文：DearMr.Smith，Recently,ourclasshadaheateddiscussionaboutthekeystosuccess.Herearetheresults.35%oftheclassmatesholdtheviewthatluck,talentandtheenvironmentplayanimportantroleinthekeystosuccess.However,themajorityarguethattosucceedinlife,wefirstneedtosetagoalandthengraduallymakeitmorepractical.Inaddition,wemustmakeeveryefforttostudyhard.Tomysurprise,10%oftheclassmateshaven'texpressedtheiropinion.Iwonderifyouwouldliketospeakoutyouropinionaboutit.Yourearlyreplywouldbehighlyappreciated.Yourstruly，LiHua
