geststhattheyarisefromthemixingofvastundergroundstoresofliquidwaterwithicymaterialnearthesurface和第六段最后一、二句thataswaterandiceofdifferenttemperaturesmingleandshift,thesurfacefractures.Thiswouldexplainthejumbledicesculptures可得知木卫二独特冰层的产生可能是因为不同温度的水和冰混合起来造成的，所以题干说法有误。故选B。18．C　题意：木卫二作为木星的卫星是最近发现的。文章第一段第一句Europa，oneofJupiter’s63knownmoons中只提及木卫二是木星63颗卫星之一，并没有说木卫二是最近发现的。故选C。19．B　题意：木卫二比月球大一点。根据文章第三段第一句Europa,whichisslightlysmallerthanEarth’smoon表明木卫二比月球稍小。所以题干说法是错误的。故选B。20．B　题意：施密特与她的同事是最早对木卫二展开研究的科学家小组。从第三段倒数第二句Formorethan10years,scientistshavewonderedwhatcausestheformations我们可以得知，十多年前已经有科学家对木卫二进行研究了，所以题干说法错误的。故选B。21．B　题意：木卫二的地貌在宇宙中是非常独特的。从第六段第二到五句theysearchedforsimilarformationshereonEarth.TheystudiedcollapsediceshelvesinAntarcticaandicycapsonvolcanoesinIceland…scientistsnowsuspectsomethingsimilarmightbehappeningon7 Europa可知南极冰架和冰岛火山冰盖也存在着相似的结构，所以木卫二的地貌并不是独一无二的。故选B。22．A　题意：存在液态水对维持生命的环境是必要的。根据文章第一段最后一句Wherescientistsfindliquidwater,theyhopetofindlifeaswell和最后一段Thatmixturemaycreateanenvironmentthatsupportslife，可知液态水对于生命来说必不可少，因此题干表述正确。故选A。第3部分：概括大意与完成句子23．E　第二段主要讲述过去人们曾以为惰性气体是完全没有活性的。所以E选项Howwerenoblegasesunderstoodinthepast?“人们过去是如何理解惰性气体的”正确。24．D　第三段主要解释什么是惰性气体，惰性气体具体包含哪些气体以及惰性气体元素在元素周期表的位置等。所以D选项Whatarenoblegases?“什么是惰性气体”贴合段意。25．D　第四段主要讲述惰性气体的化学性质稳定，是因为最外层电子满足稳定结构。所以D选项Whatcausethelowchemicalreactivityofnoblegases?“惰性气体化学性质不活跃的原因”正确。26．F　第五段第一句Becauseoftheirproperties,noblegaseshavemanyimportantapplications就讲明主旨：由于其特性惰性气体有很多重要应用。所以F选项Whataretheapplicationsofnoblegases?“惰性气体的应用”正确。27．A　题意：惰性气体化学性质不……。根据第三段第二句Thesepropertiesincludebeingmonatomic,colorless,odorless,beingabletoconductelectricity,andhavinglowchemicalreactivity可知惰性气体化学性质不活泼。故A选项“活跃的”合适。28．B　题意：在惰性气体中，氦是……。根据文中的第三段最后一句HeliumhasthelowestmolecularweightwhileRadonistheheaviest可得知，氦气是所有惰性气体中最轻的。故选B。29．D　题意：惰性气体外层电子数应为……。根据第四段第三句Noblegaseshaveafulloutershell,meaningthattheyhavecompleteelectronsintheiroutershell可得知，情性气体外层电子数应全满。故选D。30．F　题意：磁共振成像（MRI）可使手术……。根据第五段最后一句MRIallowsthedoctorto“see”thebrain.withoutoperatingonthepatient可知，通过MRI，医生可以不通过手术就看到患者头部影像。故选F。第4部分：阅读理解第一篇31．D　题意：JigmeSingyeWangchuck是谁？根据文章第一段最后一句…anewrulernamedKingJigmeSingyeWangchuckdecidedtohelpBhutantobecomemodern可知，Wangchuck是一位新上任的国王。故选D。32．D　题意：除了使不丹现代化，Wangchuck还希望为不丹做什么？根据文章第一段最后一句…KingJigmeSingyeWangchuckdecidedtohelpBhutantobecomemodern,butwithoutlosingitstraditions,说明Wangchuck不希望不丹丢掉其传统，而第三段第三句Theyarehappierwhentheycankeeptheirtraditionalcultureandcustoms也说明Wangchuck推行的GNH(国民幸福总值)政策中，如果能保持传统文化和风俗则国民会更幸福。故选D。33．A　题意：一个国家进步在GNP中体现为……。根据文中第二段第三、四句TheGNPmeasuresproductsandmoney.Whenthenumberofproductssoldincreases,peoplesaythecountryismakingprogress可知，GNP用商品和金钱来衡量，卖出的商品越多，国家似乎越进步。故选A。34．C　题意：根据GNH，人民若……会更幸福。文章第三段集中讲述GNH,人们更幸福包括theyhavehealthcare，education,andjobs；theyliveinahealthy,protectedenvironment;theycankeeptheirtraditionalcultureandcustoms;theyhaveagood,stablegovernment。由此可知C项正确。35．D　题意：现在，很多国家……。根据文章第五段第二、三句ManycountriesarenowinterestedinBhutan’sGNH.Thesecountriesareinvestigatingtheirownwaystomeasurehappiness可知，很多国家用自己的方式去衡量幸福，故选D。第二篇36．A　题意：通过这项研究科学家能够做什么？文章第一句Forthefirsttime,researchershavebeenabletohackintotheprocessoflearninginthebrain就点明研究们者第一次检测到大脑的学习过程，所以A项正确。根据文章第七段Thisworkedevenwhentestsubjectswerenotawareofwhattheywerelearning得知实验对象没有意识到他们学到了什么，但是这不代表他们没有在学习，所以B项错误。根据文章第二段Futuretherapiescoulddecodethebrainactivitypatternsofanathleteoramusician，andusethemasabenchmarkforteachinganotherpersonanewactivity可知未来有可能解码运动员或者音乐家们脑内活动的类型，而以此作为基准来教别人新技能，所以C项说法错误。根据文章第一段It’snotquiteasadvancedasaninstantkung-fudownload，可知D项也是错误的。故本题选A。37．D　题意：一个人在视知觉学习中学习某项工作时，什么能帮助他做得更好？从第三段第二句…VPL，inwhichrepetitivetrainingimprovesaperson’sperformanceonaparticulartask可得知，通过对成人的视知觉学习研究，重复训练会提高一个人某项工作的表现。A项testing意为“测试”；B项encouragement意为“鼓勘”；C项self-assessment意为“自我评价”；D项意为“重复”。故选D。38．B　题意：关于实验参与者下列哪项的叙述是正确的？A项意为“实验参与者学会了如何控制MRI机器”，文章只有第五段第一句ThevolunteerswereagainplacedinMRImachines出现MRImachines这个词，而本句与A项毫不相干，所以A项错误。根据第五段第二、三句Theparticipantswereaskedto“somehowregulateactivityintheposteriorpartofthebrain”tomakeasolidgreendiscaslargeastheycould.Theyweretoldtheywouldgetapaidbonusproportionaltothesizeofthisdisc,buttheyweren’ttoldanythingaboutwhatthediscmeant可知B项“实验中没有告知他们要学到什么”正确，与文中说法相符。C项意为“他们参加实验会获得报酬”，而上文的意思是他们被告知会得到与disc大小成正比的一笔奖金，bonus意为“奖金”，故C项错误。D项意为“他们不配合实验”，与文意不符，实际上学者们很顺利地完成了实验，所以D项错误。故选B。39．B　题意：这项研究结果意义重大在于学习……。根据文章第八段Themostsurprisingthinginthisstudyisthatmereinductionsofneuralactivationpatternscorrespondingtoaspecificvisualfeatureledtovisualperformanceimprovementonthevisualfeature表明人们可以观察到大脑活动，包括学习。这也是正是此项研究的意义所在。故选B。A项与D项文章并未提及，故错误。40．C　题意：最有可能从这项研究中受益的是什么人？根据文章最后一段Itcan‘incept’apersontoacquirenewlearning,skills，ormemory,orpossiblytorestoreskillsorknowledgethathasbeendamagedthroughaccident,disease,oraging,withoutaperson’sawarenessofwhatislearnedormemorized说明此项技术可以摄取或重置人头脑中的知识、技能或者记忆等。全文都在谈成年人，故A项错误，而B项和D项以偏概全，故错误。所以本题选C。第三篇41．C　题意：WISE的特别之处是什么？根据文章第一段最后一句…WISEhasapowerfuldigitalcamera,anditwillbetakingpicturesofsomethewildestobjectsintheknownuniverse…和第二段we’regoingtobeseeingpartsoftheuniversethatwehaven’tseenbefore可得知，WISE最特别之处在于其小小身材却携带了很强大的数码相机，而且这个相机可以拍摄到我们不曾看到过的外层空间。所以C项正确。而A项和B项的叙述不够全面。由第七段第一句That’sakeyideatowhyWISEwillbeabletoseethingsothertelescopescan’t可推断出错误。故本题选C。42．B　题意：WISE携带的相机……。根据文章第四段最后一句theWISEcameratakespicturesoffeaturesthatgiveoffinfraredradiation和第五段第三、四句Whenanordinarydigitalcamera—receivesthewavesofvisiblelightthatarereflectedoffthetree…putstheimagetogether可得知，WISE所携带的相机与普通相机不同，普通相机是通过可见光的反射拍摄物体，而WISE是通过红外辐射拍摄照片。所以B项正确，C项和D项错误。对于A项的叙述文章并未提及。故本题选B。43．D　题意：对于红外辐射……是正确的。根据文章第六段第一句Wavesofinfraredradiationarelongerthanwavesofvisiblelight和最后一句Althoughinvisibletotheeye,longerinfraredradiationcanbedetectedaswarmthbytheskin可知，红外辐射的光波比可见光波长，且红外辐射是不可见的，但是能被感知。所以D项说法正确，而A、B、C三项的说法都是错误的。故本题选D。44．C　题意：下列关于小行星的说法哪项是不正确的？根据文章倒数第二段第三至五句Asteroids,forexample,aregiantrocksthatfloatthroughspace—buttheyabsorbmostofthelightthatreachesthem.Theydon’treflectlight,sothey’redifficulttosee.Buttheydogiveoffinfraredradiation，soaninfraredtelescopelikeWISEwillbeabletoproduceimagesofthem可得知小行星不反射光，却发出红外辐射。所以C项中小行星发射可见光的说法是错误的。而A项、B项和D项说法正确。故本题选C。45．A　题意：从最后一段可以推断出棕矮星……。通过最后一段最后一句They’resodimthatthey’realmostimpossibletoseewithvisiblelight,butintheinfraredspectrumtheyglow可以得知，棕矮星红外光谱可测，证明它们发射红外辐射，所以A项正补。本段第二句Theseobjectsare“failed”stars—whichmeanstheyarenotmassiveenoughtojumpstartthesamekindofreactionsthatpowerstarssuchasthesun明确说明棕矮星与像太阳的供能星不同，所以B项错误。由本段第三句browndwarfssimplyshrinkandcooldown可知棕矮星并不治跃，所以C项错误。由本段第一句Browndwarfsareanotherkindofdeep-spaceobjectthatwillshowupinWISE’spictures可知WISE可以拍摄到棕矮星，所以D项错误。故本题选A。7 第5部分：补全短文46．F　句意：从地面上，它像是地球背上的抓痕。本处后一句Butfromhighabove,thesemarksarehugeimagesofbirds,fish,seashells,allbeautifullycarvedintotheearth描述的是从空中看“纳斯卡线”的情景，but表示转折。而F项的内容说明的是从地面上看“纳斯卡线”的情景，两句话正好形成对照，且文意非常通顺，所以本题选F。47．D　句意：瑞士作家艾里希•冯•达尼肯写道：“纳斯卡线被设计作为UFO的降落地点。”本处后一句However,itwouldprobablybeverytrickytolandaspaceshipinthemiddleofpicturesofdogsandmonkeys有关键词landaspaceship，而与D项内容的landingplaceforUFOs形成呼应，所以本题选D。48．C　句意：他称纳斯卡为“世界上最大的天文书”。本处前一句Inthe1940s,anAmericanexplorernamedPaulKosoksuggestedthatthedrawingsareachronicleofthemovementofthestarsandplanets说明PaulKosok认为纳斯卡线是星与星球运转的记录，而本处后一句Later,anastronomertestedhistheorywithacomputer讲述有天文学家验证他的理论。本处上下文都在讲PaulKosok的观点，而将C项内容补入后，前后文意清晰，所以本题选C。49．B　句意：最大的图块可能曾是某些特别仪式的地点。本段第一句…thelinesmayhavebeenmadeforreligiousreasons说明纳斯卡线可能与宗教有关系，而下一句TonyMorrisoninvestigated…andlearnedthattheysometimespraybythesideoftheroad讲述TonyMorrison发现当地人都在路边祈祷的习搭，B项的关键词ceremonies与religiousreasons与pray呼应，所以本题选B。50．E　句意：其他科学家如今正搜寻证据来证明这个说法。最后一段围绕着DavidJohnson和SteveMabee两位科学家的观点展开论述，而E项的内容说明其他科学家对这二人观点的态度是他们在找证据来支持这个观点。故本题选E。第6部分：完形填空51．D　通过文章题目可知全文在讲太阳能相关的应用。第一段最后一句leadtosolarpowerwithouttraditionalsemiconductor-basedsolarcells,solarcells意为“太阳能电池”，根据文意此句意为：研究者们找到了制造光学……的方法，只有D项battery符合。opticalbattery意为“光学电池”，与solarcells相对应。A项disc“圆盘，唱片，磁盘”，B项fiber“光纤，（织物的）质地，纤维，纤维物质”，C项instrument“仪器，手段，工具”都不合适。故本题选D。52．B　此处意为：光中有电和磁……。A项application“适用，运用”；B项components（机器、设备等的）构成要素，零件，成分”，C项resources“资源”，D项differences“差别，差异”，只有B项符合句意。故本题选B。53．B　从下文100milliontimesstrongerthanpreviouslyexpected可知这里应该选B项，意为以前科学家们认为磁场效应太弱以致到了可忽略的地步。so...that...表示太……了以至于……。A项concerned“涉及，关心，参与，卷入，使担忧”，C项expected“期望，预料，要求，认为（某事）会发生”，D项noticed“注意，通知”都不符合句意。故本题选B。54．A　根据文意及下文第五段第二句…doesnotconductelectricity,suchasglass的提示。可知此处应该选A项，conductelectricity意为“导电”，本句意为当光通过不导电的材料时，可产生相比以前所认为的10亿倍的磁效应。B项produce“生产，制作”，C项use“用，行使”，D项consume“消耗，耗尽”都不符合句意。故本题选A。55．D　此句意为：在这些条件下，磁效应产生的力……强的电效应。A项reactive“反应的，活性的”，B项preferable"更好的，更可取的，略胜一筹的”，C项due“预定，适当的，应有的，由于”，D项equivalent“相当的，等价的”，equivalentto意为“相当于……”。根据句意，应该选D，其他选项意思都不合适。故本题选D。56．A　此句意为：太阳能电池中，……进入材料，被吸收然后产生热。全文都在讲电光磁，因此A项light正确。B项electricity“电力，电流”,C项chemical“化学物品”，D项gas“气体’’都不符合句意。故本题选A。57．B　此句意为：强磁化可以通过强光诱导产生，最终它可以提供电容性的……。A项plant“植物，设备，工厂”，B项source“本源，源头”，C项equipment“设备，装备”，D项line“线路，线条”。powersource意为“电力”，符合句意。故本题选B。58．C　此句意为：光电场能导致电荷分离，或者将材料中的正负电荷……。很明显，后半句和前半句的意思相同，所以本题选C项apart“分散地，分开地”。其他选项都不合适、故本题选C.59．C　此句意为：这样便形成一个电压，与电池里的……类似。此处要填入一个代词，指代前面的voltage，故本题选C。60．A　此句意为：光要射入不导电的……，如玻璃。很显然玻璃是一种不导电的介质，与前文throughamaterialthatdoesnotconductelectricity相呼应，所以A项“材料，介质”为正确。而B项device“装罝，设备”，C项detector“探测器，检测器”，D项meter“测量仪表，计量器”都不符合句意。故本题选A。61．D　此句意为：太阳光本身没有这么……，但是正在寻找的新介质可以在低的强度下运转。intense与前面anintensityof10millionwattspersquarecentimeter和后面的atlowerintensities相呼应，所以本题选D项intense“强烈的”。A项bright“明亮的”，B项faint“微弱的，模糊的”，C项visible“看得见的，明显的”用于此处都不合适，故本题选D。62．B　as...as...意为“同……一样达到某种程度，与……等同”，此句意为：像大阳光的非相干光在理论上几乎和激光一样能够有效地导致电荷分离。故本题选B。63．B　此句意为：这项新的……能使太阳能更低廉。A项skill“技能，技巧”，用于指人具有专门知识，业务精通，且经验丰富，B项technology“技术”,C项miracle“奇迹”，D项prototype“原型，雏形”，根据文意应该为新技术，故选B。64．A　此句意为：制造太能电池，必须进行……半导体加工。A项extensive“广阔的，广泛的”，B项interactive“互相作用的，相互影响的”，C项selective“精选的”，D项intensive“加强的，强烈的”。文中意思应为大量的半导体加工，故本题选A。65．D　根据上一句可知，玻璃集合了lensestofocusthelightandafibertoguideit两者需求，所以此处用both。故本题选D。7
