考查冠词。由空后的“mostinteresting”的提示可知，此处为形容词的最高级，应用定冠词修饰。2．whose 考查定语从句的引导词。whose引导非限制性定语从句，在从句中作定语，先行词为JoanandBernice。3．pleasure 考查词性转换。结合语境和冠词a的提示可知，此处应用名词形式。4．happier 考查形容词的比较级。否定词与比较级连用表达最高级含义，与上文的joy呼应。5．wastalked 考查动词的时态和语态。由语境可知，Everyperson和talk之间是被动关系；再由前一句的时态可知，应用一般过去时的被动语态。8\n6．is 考查动词的时态。由附加问句“isn'tshe？”可知，此处应用is。7．how 考查宾语从句的连接词。how引导宾语从句且在从句中修饰形容词wonderful。8．them 考查代词。介词about后应跟代词的宾格形式且表示“他们”，故填them。9．toward(s)/to 考查介词。attitudetoward(s)/tosb.意为“对某人的态度”，符合语义。10．thankful 考查词性转换。be动词后一般跟形容词作表语，故此处用形容词形式。***完形填空Fallingoffaboxcarandlandingonmyhead，IlostmysightwhenIwasfouryearsold.NowIamthirtytwo.Ican__1__rememberthebrightnessofsunshine.Itwouldbewonderfultoseeagain，__2__atragedycandostrangethingstopeople.It__3__tomethatImightnothavecometolovelifeasIdonowifIhadn'tbeenblind.Myparentsandmyteachersawsomething__4__me，andtheymademewantto__5__againstblindness.Thehardest__6__Ihadtolearnwastobelieveinmyself.IfIhadn'tbeenabletodothat，Iwouldhave__7__downfortherestofmylife.WhenIsay__8__inmyselfIamnottalkingabout__9__thekindofselfconfidencethat__10__medownanunfamiliarstaircase(楼梯)alone.ButImeansomethingbiggerthanthat：theassurancethatIamarealpositiveperson__11__imperfections.Ittookmeyearstoobtainthis__12__.Ithadtostartwiththe__13__.Onceamangavemeanindoor__14__.“Ican'tusethis，”Isaid.“Takeitwithyou，”he__15__me，“androllitaround.”The__16__stuckinmyhead.“Rollitaround！”ByrollingtheballIcouldhearwhereitwent.ThisgavemeanideahowtoachieveagoalIhadthought__17__.AttheSchoolfortheBlindI__18__anewkindofbaseballcalledthe“groundball”．AllmylifeIhavesetaseriesofgoalsandthentriedtoreachthem，oneatatime.Ihadtolearnmy__19__.IwouldfailsometimesanywaybutontheaverageImade__20__.1．A.randomlyB．abruptlyC．roughlyD．completely2．A.soB．butC．thusD．and3．A.occurredB．referredC．broughtD．turned8\n4．A.ofB．forC．toD．in5．A.getB．fightC．findD．drop6．A.methodB．experienceC．lessonD．manner7．A.brokenB．putC．settledD．lay8．A.courageB．ambitionC．beliefD．power9．A.firmlyB．simplyC．fairlyD．slightly10．A.stopsB．helpsC．findsD．gives11．A.despiteB．besidesC．withoutD．unlike12．A.descriptionB．existenceC．accusationD．recognition13．A.intelligenceB．incidentC．troubleD．determination14．A.chairB．baseballC．gameD．design15．A.urgedB．blamedC．greetedD．teased16．A.goalsB．wordsC．imagesD．ideas17．A.valuableB．reasonableC．impossibleD．unbearable18．A.discoveredB．equippedC．formedD．invented19．A.limitationsB．advantagesC．puzzlesD．personalities20．A.senseB．progressC．mistakesD．decisions8\n【解题导语】本文是一篇夹叙夹议文。文章主要讲述了“我”在四岁的时候失去了视力，但通过一件小事，“我”学会了自信，并逐渐取得进步的过程。【核心词汇】tragedy悲剧 imperfection缺点ontheaverage一般来说 roughly粗略地1．C 考查副词。“我”四岁时失去视力，现在已经三十二岁了。由此可推知，此处表示“我”粗略地记得，故选C。roughly“粗略地，大致上”。2．B 考查连词。根据语境可知，上下文之间是转折关系，故选B。3．A 考查动词。“我”想到如果“我”没有失明“我”可能不会像现在这样热爱生活。Itoccurstosb.that...为固定句型，意为“某人想到……”。4．D 考查介词。“我”父母以及老师看到了“我”内在的一些东西，他们让“我”想要与失明作斗争。根据语境可知，此处应选D。5．B 考查动词。参见上题解析。fightagainst...“与……作斗争”。6．C 考查名词。“我”学到的最困难的一课(lesson)就是要相信“我”自己。7．A 考查动词。如果“我”做不到那样的话，“我”可能已经精神崩溃了。breakdown“(在健康或精神等方面)垮掉”。8．C 考查名词。根据上文中的“tobelieveinmyself”可知，此处应选C项与上文相照应。9．B 考查副词。“我”说的信心并不仅仅(simply)指帮助(helps)“我”走下陌生楼梯的自信。10．B 考查动词。参见上题解析。11．A 考查介词。尽管“我”是一个不完美的人，但是“我”是一个积极的人。despite“尽管”，符合语境。12．D 考查名词。“我”花了很多年才认识到这一点。A项意为“描述”；B项意为“存在”；C项意为“控告”；D项意为“认识”。13．B 考查名词。这从一件小事开始。A项意为“智慧”；B项意为“小事”；C项意为“麻烦”；D项意为“决心”。14．B 考查名词。根据下文中的“anewkindofbaseball”可知，此处指棒球。15．A 考查动词。根据语境可知，此处指他一直在敦促“我”。urge“强烈要求，敦促”。16．B 考查名词。他所说的话(words)印在“我”的脑海中，故选B。17．C 考查形容词。这给了“我”一个如何实现”我”认为不可能(impossible)的目标的想法。A项意为“有价值的”；B项意为“合情理的”；C项意为“不可能的”；D项意为“无法容忍的”。8\n18．D 考查动词。在盲人学校“我”发明(invented)了一种新的被称之为“地滚球”的棒球。A项意为“发现”；B项意为“配备”；C项意为“形成”；D项意为“发明”。19．A 考查名词。“我”不得不了解自己的不足之处。limitation“(某人或某物的)局限性，不足之处”。20．B 考查名词。“我”有时会失败，但一般说来“我”取得了进步。makeprogress“取得进展”。***短文改错LiMingisafriendofmine.I'mgladhechangedgreatlyinthepasttwoyears.Iclearlyrememberhewasquitefattwoyearsbefore.Hegottiredsoeasythathecouldn'ttakeexercise,thatmadehimveryupset.Later,herealizedunlesshewentonlikethat,hewouldendupachievenothing.Sohemadeuphismindstomakeachange.Hewentrunningeverymorningandplayedthebasketballeveryafternoon.Besides,hefollowedadietofmorevegetablesorlessmeat.Graduallyhebegantoloseweight.Heisnowanenergeticboyingoodhealth.Sowhenfacedwithproblems,weshouldovercomeitwithgreatdeterminationandstrongwillpower.答案：LiMingisafriendofmine.I'mgladhechangedgreatlyinthepasttwoyears.Iclearlyrememberhewasquitefattwoyears.Hegottiredsothathecouldn'ttakeexercise,madehimveryupset.Later,herealizedhewentonlikethat,hewouldendupnothing.Sohemadeuphistomakeachange.Hewentrunningeverymorningandplayedbasketballeveryafternoon.Besides,hefollowedadietofmorevegetableslessmeat.Graduallyhebegantoloseweight.Heisnowanenergeticboyingoodhealth.Sowhenfacedwithproblems,weshouldovercomewithgreatdeterminationandstrongwillpower.难项分析：第一处：changed前加has 考查动词的时态。根据时间状语inthepasttwoyears可知，此处表示从过去开始发生的动作，并对现在造成了影响。因此，应用现在完成时。故在changed前加has。8\n第二处：before→ago 考查副词。before指从过去某刻起若干时间以前，常与完成时连用，ago指从此刻起若干时间以前，常与过去时连用。根据上下文可知，此处讲述的是过去的事情，故将before改为ago。第五处：unless→if 考查连词。“hewentonlikethat(他继续像那样)”是“hewouldendup...nothing”的条件，因此应用if引导条件状语从句。故将unless改为if。***8
