特色等相关信息。1．A考查细节理解。根据FindThrillsataThemePark部分中的“ExperiencethrillridesandattractionsatSixFlagsDiscoveryKingdom...”可知，在六旗探索王国可以体验惊险之旅。故选A项。2．B考查细节理解

。根据CruiseontheBay部分中的“Forpeoplewholikethethrillofspeedandwindintheirhair...”可知，对于热爱速度与风的游客，CruiseontheBay这项活动会很有吸引力。故选B项。3．D考查细节理解。根据RideaBikeOver

theGoldenGateBridge部分中的“...withanall-daybikerentalfromBlazingSaddles.Theirlightbikes,combinedwiththeirnew,freemobileapp...”可知，从BlazingSaddles租自行车可

以获得免费的移动应用程序。故选D项。【语篇解读】本文讲述了一个等待治疗的残疾人把自己的治疗基金捐献给一个五岁的孩子，帮这个孩子去实现“走路”的愿望。他的慷慨和对别人的无私帮助与爱心感动了很多人，在人们的捐助下，这个孩子的家庭很快筹够

了治疗费用，并承诺用剩下的钱去帮助其他需要医疗帮助的孩子们。4．D考查细节理解。根据文章第三段中的“Then,afterconsideringthathisowndreamofwalkingcouldbeyearsaway,hedonatedhis$30,000toBrec

on'scause.”可知，他把自己治疗需要的钱捐了出去。故选D项。5．A考查词义猜测。根据第四段中的“They'vepromisedtogivetheextrafunds,about...totheTreeofHopecharity...”可知，

筹款有剩余的钱，因此推测exceeded的含义为“超过”。故选A项。6．C考查细节理解。根据第四段中的“Dan'sgenerosityreceivedagreatdealofattention,andcontribu

tionsstartedpouringin...”可知，丹的慷慨引起了大家的关注，人们以他为榜样，捐款像潮水般涌来。故选C项。7．B考查细节理解。根据第四段中的“They'vepromisedtogivetheex

trafunds,about$17,000,totheTreeofHopecharity,whichhelpssickchildrenintheUnitedKingdomfindspecializedme

dicalhelp.”可知，他们将把钱捐赠给TreeofHope这个慈善机构。故选B项。【语篇解读】本文是一篇议论文。文章以9岁的孩子Annie的父母由于争吵导致最终离婚的叙述引入主题，接着通过论据论证了“在不幸的婚姻中，离婚并不

是最糟糕的事”这一主题。【难句分析1】No,whatAnnieremembersmostarethehorriblefightsleadinguptotheannouncementaboutthedivorc

ewhichwas,asturnedout,despiteherparents'anxietyabouttellingher,“notthatbigofadeal”．分析：该句为主从复合句。句中“whatAnnieremembersmost”为what引导的主语从

句；“whichwas,asturnedout,anddespiteherparents'anxietyabouttellingher,‘notthatbigofadeal’”为which引导的定语从句，修饰先行词thedivorc

e。译文：不，Annie记得最清楚的是导致(她的父母)宣告离婚的可怕的争吵，尽管她的父母害怕告诉她，但是正如事实证明的那样，离婚“没什么大不了的”。【难句分析2】Thehomelifeofchildrenwhoseparentshaveanunhappymarri

ageisoftenfarfromideal,andwhat'sworse,parentswillcompoundtheproblembytakingtheirunhappinessoutonthechildren.分析：该句为并列句。前一分句中

“whoseparentshaveanunhappymarriage”为whose引导的定语从句，修饰先行词children,whose在从句中作定语。译文：父母婚姻不幸福的孩子的家庭生活往往很不理想，更糟的是

，父母把他们的不幸福发泄在孩子身上，会使问题更加严重。8．A考查细节理解。根据第一段中的“EverynightafterIwenttobed,Iwouldhearmyparentsfighting.Itm

ademereallyunhappy”可知，Annie的父母每天晚上都吵架，这让她感到很不幸福。故A项正确。9．B考查推理判断。根据第二段中的“AccordingtopsychologistLynnMartingdale,hearingtheirparentsarguingisoften

morestressfulforchildrenthanseparationanddivorce”可知，心理学家LynnMartingdale认为，听父母吵架对孩子来说往往比分居和离婚更有压力，据此可以判断，LynnMartingdale认为维持不幸福的婚

姻会更加伤害孩子。故B项正确。10．C考查主旨大意。根据最后一段中的“Aftertrackingthesefamiliesfor5years,theyfoundthatthechildrenofthep

arentswhoeventuallygotdivorcedwerenotworseoffthanthechildrenofthosewhoremainedtogether,andinsomecasesfarbetter”可知，在对这些家庭进

行了5年的跟踪调查后，他们发现，最终父母离婚的孩子并不比那些父母仍在一起的孩子生活得更差，在某些情况下，他们的生活更好。据此可知，最后一段旨在通过研究进一步说明本文的论点：在不幸的婚姻中，离婚不是最糟糕的选择。故C项正确。11．B考查主旨大意。根据第一段第二句和Annie所说的话可知，

对孩子们来说，父母的争吵比离婚更糟糕；结合第二段中的“thereisagreatdealofevidencetosuggestthat‘stayingtogetherforthesakeofthechildren’isnotwhatshouldbeencour

aged,andmaydomoreharmthangood”可以判断，本文的主旨是：在不幸的婚姻中，和离婚相比，父母为孩子而在一起给孩子的伤害最大。最后一段的研究也论证了这一点。故B项最适合作为本文标题。【语篇解读】该文主要介绍了从纤维素中提取氢气这一新方法。【熟词生义

】study常用义：v.学习例句：ShehasbeenawardedascholarshiptostudyatHarvard.她获得了去哈佛大学读书的奖学金。本文义：n.&v.研究例句1：Recentstudiesshowthatwomens

tillgetpaidalotlessthanmen.最近的调查表明，女性的薪水仍比男性的要低很多。例句2：ScientistsarestudyingthephotographsofMarsforsignsoflife.科学家们正在研究火星的照片，寻求生命的迹象

。【难句分析】Theresearchersstudiedtheeffectivenessofthreemetal-basedcatalysts,ofwhichnickel(镍)especiallyinterestedtheresearchers,asi

tisamuchmorecommonmetalthangoldandpalladiumanditsavesmoremoney.分析：本句是一个复合句。which引导非限制性定语从句，指代先行词threemetal-basedcatalysts;as引导原因状语从句。译文：研

究人员研究了三种金属基催化剂的效果，其中镍尤其让研究人员感兴趣，因为它与金子和钯比起来更常见，而且也更省钱。12．D考查细节理解。根据第二段中的“hydrogencanbetakenfromgrassinusefulamountswiththehel

pofsunlightandacheapcatalyst”可知，从草中获取氢气需要阳光和催化剂。13．A考查细节理解。根据第三段中的“itcouldleadtoasustainablewayofmakinghydro

gen”可知，这种方法是可持续的；根据第七段内容可知该方法成本低且无污染，故选A。14．C考查细节理解。根据第七段最后一句“Theresearchersstudiedtheeffectivenessofthreemetal-basedcatalyst

s,ofwhichnickel(镍)especiallyinterestedtheresearchers,asitisamuchmorecommonmetalthangoldandpalladiumanditsavesmoremoney”可知，研究人员对

金属镍感兴趣是因为其更常见，且价格更廉价。15．B考查主旨大意。根据第一段点题，并结合最后一段的再次强调说明，以及对全文的整体理解可推知，本文主要讲述的是从纤维素中制造氢气这一新方法。第二节【语篇解读】本文是一篇说明文。详细

介绍了几种骑自行车的比赛。1．C根据空处所在的位置可知，该句承上启下；由下文介绍的几种骑自行车比赛可知，C项“热衷骑自行车的人经常筹备参加骑自行车比赛”符合语境。2．B根据空后的“becausethebicyclesarespreadoutan

darenotlikelytorunintoeachother”可知，由于自行车是分散的，不太可能互相碰撞；故对于新手来说这种比赛是安全的，故B项正确。3．F根据空处上下文可知，空处承接上文，继续介绍这种难度

较大的骑自行车比赛具体的比赛内容，故F项正确。且F项中的“thecityblocks”与该段中的“Afewcityblocks”呼应。4．D根据空后一句“Racershavetocoveranywherefrom35milestoalmost3,000miles”可知，参赛者必须骑

35英里到近3000英里的路程；又结合本段第三句的内容可知，D项“道路比赛通常是路程最长的骑自行车比赛”符合语境。5．A根据空后的“theyoftenjoinbicyclinggroupsandbecomelicensedra

cers”可知，他们经常参加自行车团体，并成为有执照的参赛者；据此可推知，空处是说这些骑自行车者越来越有经验，故A项正确。课时练(二)语言知识运用第一节【语篇解读】本文是一篇记叙文，讲述了暴风雨降临时约翰·安德伍德营救遭遇险境的Hammonds夫妇的故事。1．D根据下文中多次出现的help及文

章第一句可知，作者认为有人天生乐于助人。givesb.ahand固定短语，“帮助某人”，选D项。2．B有人只是恰好在恰当的时间出现在恰当的地点，故选B项。3．C结合下文安德伍德帮助被困夫妇的事件可知，此处意为约翰·安德伍德就是这样的例子。case“事例，实例”，故选

C项。4．A结合上文内容可知，此处指暴风雨在他家附近降临了，故选A项。5．D安德伍德正在去帮助他的妹妹的路上，这时道路被洪水淹没了。下文中的“thewaterwasrisingfast”是提示，故选D项。6．C“如果我有能力去做好事，我就应该去做”，这是安德伍

德的信念，故选C项。7．C安德伍德认为做好事不应该有任何理由，故选C项。8．D根据上文中的“Hesawsomeotherdriversgetstuck,sohegotoutofhistrucktohelp.”可知，此处vehicle符合语境，故选D项。9．A此处指有人

高声喊：“我父母！我父母！”，故选A项。10．B根据下文的“whenthewalls...felldown”可知，一个12岁的男孩跑向安德伍德，说他的父母被困住了。trap“困住；使陷于危险中”，故选B项。11．BHammonds夫妇去地下室拿东

西，墙壁不能够承受雨水的重量，倒塌了，两人无法脱身。fail“未能(做到)”，故选B项。12．C参见上题解析。reunite“重逢，再次相聚”；escape“逃脱，摆脱”；survive“生存，存活”，故选C项。13．A根据上文中的“the

waterwasrisingfast”和“soUnderwoodtookactionatonce”可知，时间(Time)至关重要，于是他立即行动起来，故选A项。14．D在这种情况下，任何不当的操作都会加大危险。幸运的是，安德伍德有作承包商的经验，故选D项。15．B安德伍德认为在客厅地板上挖一个洞

是一个安全的方法。此处safe与前面的dangers形成对比，故选B项。16．A根据下文中的“Underwoodsavedtheirlives”和“AnnOtto,whowasinchargeofthe

23rdAnnualActsofCourageAwards...Underwood”可知，安德伍德因勇敢的行为获奖。他凭借体力，耐心和勇气救了Hammonds夫妇，故选A项。17．C根据空前的“Hesaidhedidwhatanyonewoulddo,buttha

t'snotnecessarilytrue”可知，要把自己置于危险的境地去救别人是很难做到的，故选C项。18．B这是美国红十字会把奖项授予他的原因。honor“给……荣誉；表彰”符合语境，故选B项。19．A这个奖应该颁给那些像安德伍德那样在紧急情况

下表现得英勇无私的英雄。goto“归于，被给予”，故选A项。20．D参见上题解析。信息词Courage可提示答案，courageously“勇敢地”，故选D项。第二节【语篇解读】本文介绍了有关脸盲症的相

关信息，以及有关脸盲症的最新研究，该研究有助于我们对如何记住我们周围的世界有一个更深的了解。1．simply考查副词。修饰形容词应用副词，故用副词simply修饰其后的impossible。2．whose考查定语从句。分析句子结构可知，空处引导非限制性定语从句，作

actualname的定语，所以正确答案是whose。3．wasthought考查时态和语态。根据该句中的“Therewasatime”可知，应用一般过去时；分析句子结构可知，此处是sth.bethoughttobe结构，意为“某物被认为……”，所以正确答案是wasthought。4．s

tudies考查名词的单复数，根据空前的recent以及空后的haveshown可知，此处应用名词的复数形式，所以正确答案是studies。5．a考查冠词。分析句子结构可知，__5__professor

ofpsychologicalandbrainsciences是Duchaine的同位语，此处泛指一位教授，故用不定冠词；professor的发音以辅音音素开头，所以正确答案是a。6．whether/if考查宾语从句。分析句子结

构可知，空处引导宾语从句，同时结合句意及句末的ornot可知，连接词应是whether或if，所以正确答案是whether/if。7．resulting考查现在分词。分析句子结构可知，本句已经有谓语canidentify，故此处应用现在分词短语作后置定语，所以正确答案是

resulting。8．shown考查过去分词。分析句子结构可知，when引导状语从句，空处为thetesteeswereshown的省略形式，所以正确答案是shown。9．itself考查反身代词。根据句意并分析句子结构可知，空处作

thisstudy的同位语，应用反身代词，所以正确答案是itself。10．deeper考查形容词的比较级。根据空前的amuch以及空后的understanding可知，空处应用形容词的比较级，表示对于如何记住我们周围的世界有一个更深的了解，所以正确答案是deeper。课时练(三)写作

animportantroleinhelp⑩helpingmefindagoodjobinthefuture.①schoolmate改为schoolmatesschoolmate是可数名词，且其与语境中的teachers呼应

，故用其复数形式。②what改为that分析句子结构可知，It在句中作形式主语，此处引导的从句作真正的主语，且此处在从句中不作句子成分，故将what改为that。③删除an根据固定搭配forexample“例如”，故删除a

n。④come改为comes主语it是第三人称单数，且此处叙述的是一般的情况，故谓语动词用第三人称单数形式，即comes。⑤it改为them此处应用them代指该句中的复数名词opinions。⑥after改为before根据语境及常识可知，讨论之后再做最终的决定是必要的，故用连词be

fore。⑦had改为has结合语境可知，此处表示过去的事情对现在造成某种影响，故用现在完成时。⑧communicate后加with根据固定用法communicatewithsb“与某人交流”，故在communicate后加w

ith。⑨certain改为certainly修饰动词应用副词，故用副词certainly修饰动词play。⑩help改为helping介词后跟动名词作其宾语，故用动名词helping。第二节书面表达【参考范文】DearCarol，I'mastuden
