【答案】24.D25.B26.B27.A
【解析】这是一篇说明文。短文介绍了重新阅读的意义和益处并向读者介绍了作者每年重读的三本书。作者鼓励读者去重新阅读书籍。
24.推理判断题。根据第一段最后两句“Butbooksdon’tchange,peopledo.Andthat’swhatmakestheactofrereadingsorichandtransformative.(但是书没变，人变了。那就是使重新阅读行为如此丰富和富于变化之处)”和第二段“Thebeautyofrereadingliesinthatourbondwiththeworkisbasedonourpresentregister.Itistrue,theolderIget,themoreIfeeltimehaswings.(重新阅读的美妙之处在于我们与作品的联系是基于我们现在的心理状态。真的，我年纪越大，就越觉得时光飞逝。)”可推知，作者喜欢重新阅读是因为重新阅读可以扩展对自己的理解。故选D项。
25.推理判断题。根据倒数第二段“Publishedin1964,it’shisclassicmemoirof1920sParis.”及“anagingwriterlookingbackonanambitiousyetsimplertime”可知，这本书出版于1964年，这是他关于20世纪20年代在巴黎的经典回忆录，是他老年时对那些野心勃勃却更简单的日子的回顾。由此可判断出AMovableFeast是关于海明威年轻时的生活。故选B项。
26.词义猜测题。根据最后一段中“whilemoneyisindeedwonderfulandnecessary,(虽然金钱确实是美妙而必要的)”可知，前后句为转折关系，根据上下文的语境可推知，“rereadinganauthor’sworkisthehighestcurrencyareadercanpaythem.”意为“但是但重新阅读作品是读者能支付给他们的最高回报”，由此判断出划线词的意思是“回报”。故选B项。

【答案】28.C29.D30.A31.B
【解析】这是一篇说明文。短文介绍了竞走相比跑步有诸多的优势，但是之前受过伤的人，要想从事这样运动要谨慎，最好咨询专家的建议。
29.细节理解题。根据最后一段“Asaresult,shesays,someoftheinjuriesassociatedwithrunning,suchasrunner’sknee,areuncommonamongracewalkers.”可知，一些与跑步有关的损伤，比如跑步者的膝盖，在竞走者中并不常见。由此可知，竞走与跑步相比的优势是不太可能导致膝盖受伤。故选D项。
30.细节理解题。根据最后一段Dr.Norberg说的话“Infact,anyonewishingtotryracewalkingshouldprobablyfirstconsultacoachorexperiencedracertolearnpropertechnique(事实上，任何想尝试竞走的人都应该首先咨询教练或有经验的竞走运动员，学习适当的技巧。)”可知，Dr.Norberg建议想尝试竞走的人征询专家的建议。故选A项。
31.推理判断题。根据第一段“Racewalkingsharesmanyfitnessbenefitswithrunning,researchshows,whilemostlikelycontributingtofewerinjuries.Itdoes,however,haveitsownproblem.”可知，研究表明，竞走和跑步一样有很多健身益处，而且它还很少导致受伤。不过，它也有自己的问题。由此判断出作者对于竞走的态度是客观的。故选B项。

【答案】28.A29.A30.D31.B
【解析】本文是说明文。介绍了美国新奥良和布鲁克林举办了不同寻常的时装秀。展出海狸鼠制成的皮衣。海狸鼠们每年都在破坏大片的湿地，因此设计师称这是一种环保的举措，科学家们也对海狸鼠损坏生态平衡表示了担忧。
28.推理判断题。根据第二段UnusualfashionshowsinNewOrleansandBrooklynhaveshowcasednutriafurmadeintoclothesindifferentstyles.“Itsoundscrazytotalkaboutguilt-freefur-unlessyouunderstandthatthenutriaaredestroyingvastwetlandseveryyear,”saysCreeMcCree,projectdirectorofRighteousFur.得知，美国新奥尔良和布鲁克林举办了不同寻常的时装秀，时装秀上展出海狸鼠皮制成的不同风格的衣服，项目总监CreeMcCree说：“除非了解海狸鼠正每年破坏大片湿地，否则谈论无罪感皮衣是很疯狂的事情”，可以判断出由于海狸鼠对生态造成了巨大的破坏，这场海狸鼠皮衣时装秀销售的是无罪恶感皮衣。故选A。
29.推理判断题。根据第三段ScientistsinLouisianaweresoconcernedthattheydecidedtopayhunters$5atail.得知，科学家们如此担心以至于他们决定按照一条海狸鼠尾巴付给猎人们5美元，可以推断出科学家们担忧海狸鼠们严重破坏生态平衡，。故选A。
30.词义猜测题。根据第五段Thefurtradekeptnutriaincheckfordecades,butwhenthemarketfornutriacollapsedinthelate1980s,thecat-sizedanimalsmultipliedlikecrazy.得知，毛皮贸易使海狸鼠受到了几十年的控制，但是当海狸鼠市场在20世纪80年代末崩溃时，这种猫大小的动物数量疯长，根据but判断，这是转折关系，以前由于皮毛交易，海狸鼠处于控制，现在这种海狸鼠之所以能够数量激增，是由于市场不再销售海狸鼠皮毛导致的，可以推断出划线词collapsed是和D.crashed倒闭的意思最相近。故选D。
31.推理判断题。根据第二段ModelPaigeMorgansays,“Togivepeopleaguilt–freeoptionthattheycanwearwithoutsomeonethrowingpaintonthem-Ithinkthat’sgoingtobeamassivething,atleastinNewYork.”得知，为了给人们一种无罪的选择，人们可以穿皮衣而不被人们泼油漆，我认为在纽约将是一件巨大的事情，根据模特摩根所说得知，在纽约穿皮质衣服是有风险的。故选B。

【答案】61.B62.A63.B64.D
61.词句猜测题。根据下文workingoutbeforebreakfastmaybemorebeneficialforhealththaneatingfirst可知，早餐前锻炼可能比先吃饭再锻炼对健康更有益，因此推断这里说的是那些不吃早饭先锻炼的人，因此推断划线词与B项“不吃早饭能应付”意思相近。故选B。
62.细节理解题。根据第三段的Theyfirstfound10overweightandinactivebutotherwisehealthyyoungmen,whoselifestylesarefarbetterandworse,representativeofthoseofmostofus.可知，他们首先找到了10个超重的，不活跃但健康的年轻人，他们的生活方式可以说更好，也可以说更糟，代表了我们大多数人。因此可知，实验时选择的10个人的生活方式代表了普通人。故选A。
63.细节理解题。根据第六段的Asaresult,theyburnedmorefatduringwalksonanemptystomachthanwhentheyhadeatenfirst.Ontheotherhand.theyburnedslightlymorecalories(卡路里),onaverage,duringtheworkoutafterbreakfastthanafterfasting.可知，结果，他们空腹散步时燃烧的脂肪比他们首先吃东西时所燃烧的脂肪要多。另一方面。平均而言，他们在早餐后锻炼时燃烧的卡路里略多于禁食后。因此可知，锻炼前吃早饭消耗更多一点的热量。故选B。
64.推理判断题。根据最后一段Theimplicationoftheseresultsisthattogainthegreatesthealthbenefitsfromexercise,itmaybewisetoskipeatingfirst.可知，这些结果的暗示，为了从运动中获得最大的健康益处，先不吃东西可能更明智。因此推断早饭前的体育锻炼对健康更有益。故选D。

【答案】12.D13.D14.A15.C
12.细节理解题。根据第一段中的“AccordingtoarecentstudyintheJournalofConsumerResearch,boththesizeandconsumptionhabitsofoureatingcompanionscaninfluenceourfoodintake”可知，根据消费者研究杂志最近的一项研究，我们的饮食伙伴的大小和消费习惯都会影响我们的食物摄入量。因此这项研究是关于饮食行为的。故选D。
13.词义猜测题。根据前半句“Andcontrarytoexistingresearchthatsaysyoushouldavoideatingwithheavierpeoplewhoorderlargeportions（份）”可知，现有的研究认为：你应该避免和体重较重、点大份饭菜的人一起吃饭。后半句认为，你真正应该避免的是thebeanpoleswithbigappetites。由contraryto可推断出，画线词和heavierpeople（超重的人）相反，结合选项，D选项（瘦瘦高高的人）正好和heavierpeople正好相反。故选D。
14.推理判断题。根据第二段的“Totesttheeffectofsocialinfluenceoneatinghabits,theresearchersconductedtwoexperiments”可知，为了测试社会影响对饮食习惯的影响，研究人员进行了两个实验。根据倒数第三段的内容可知，在两个实验中，胖的和瘦的演员都吃了大量的食物。参与者也照做，吃的食物比平常多。然而，当演员是瘦的时候，参与者们服用的食物更多。由此推断，研究人员雇用演员是为了看看她如何影响参与者。故选A。
15.推理判断题。根据最后一段中的“Ifanoverweightpersonishavingalargeportion,I’llholdbackabitbecauseIseetheresultsofhiseatinghabits.Butifathinpersoneatsalot,I’llfollowsuit.Ifhecaneatmuchandkeepslim,whycan’tI”可知，如果一个超重的人吃很大一份，我会忍住一点，因为我看到了他饮食习惯的结果。但如果一个瘦的人吃很多，我会跟着做。如果他吃得多保持苗条，为什么我不能呢？因此推断我们是根据我们对他人的看法（即：如何看待他人）来调整影响的。故选C。

【答案】46.A47.D48.D49.C50.B
46.推理判断题。根据第二段中的“Itproducesadeafeningsoundsopainfulthatittemporarilydisablesaperson.ThenoisefromtheLRADisdirectedlikearayoflightandtravelsonlyintotheearsofthatperson,butitisnotdeadly.”可知它发出震耳欲聋的声音，这种声音令人如此痛苦以至于它会使人暂时丧失能力。LRAD发出的噪音像光线一样被引导，只进入那个人的耳朵，但不会致命。由此可推知，LRAD会导致暂时性听力损失。故选A。
47.细节理解题。根据第三段中的“Well,itfunctionsbyanalyzingthewavesoftheincomingsoundandcreatingasecondsetofoutgoingwaves.Thetwosetsofwavescanceleachotherout.Simplyturnthemachineonpointitatthetarget,andyourpeaceandquietcomesback.”可知，它的功能是通过分析传入声音的波，并产生第二组传出的波。这两组波会相互抵消。只要打开机器对准目标，你的宁静就会回来。由此可知，静音机是一种专门设计用来阻止有害声音影响你的设备。故选D。
48.细节理解题。根据最后一段中的“Aspotlightlightsuponlyonesectionofastage;similarly,a“spotsound”createsacircleofsoundinonetargetedarea.”可知，聚光灯只能照亮舞台的一个部分；类似地，一个“spotsound”在一个目标区域创建一个声音圈。由此可知，spotsounds和聚光灯的共同特性是它们可以被定向到一个特定的区域，故选D。
49.细节理解题。根据最后一段中的“Aspotlightlightsuponlyonesectionofastage;similarly,”spotsound”createsacircleofsoundinontargetedarea.Thiscanbeusefulforbusinessessuchasrestaurantsandstoresbecauseitoffersanewwaytoattractcustomers.Restaurantscanofferachoiceofmusicalongwiththevariousfoodchoiceonthemenu,allowingcustomersmorecontrolovertheatmosphereinwhichtheyaredining.”可知，聚光灯只能照亮舞台的一个部分；类似地，一个”spotsound”在一个目标区域创建一个声音圈。这对餐馆和商店等企业很有用，因为它提供了一种吸引顾客的新方式。餐厅可以提供音乐选择与菜单上的各种食物选择，让顾客更多地控制气氛，在他们用餐。由此可知，定向音响可以用于不同的商业音乐选择。故选C。

【答案】25.C26.D27.A
26.推理判断题。根据第四段第一句中“adaptivesignalsarenotacure-allforjammedroadways(但自适应信号并不是解决拥堵道路的万能药)”及第二句中“othersaresojammedthatonlyasharpreductioninthenumberofcarsontheroadwillmakeameaningfuldifference(其他城市交通堵塞如此严重，只有减少道路上的车辆才能起有意义的作用)”可推知，KevinBalke认为适应性信号灯对于交通堵塞很严重的城市没有太大帮助。故选D项。
27.推理判断题。根据第二段最后一句“Theselights,knownasadaptivesignals,haveledtosignificantdeclinesinboththetroubleandcostoftravelsbetweenworkandhome.(这些灯，被称为适应性信号灯，已经大大减少了通勤的麻烦和花费)”最后一段第一句“InBellevue,theswitchtoadaptivesignalshasbeenalessoninthevalueofwelcomingnewapproaches.(在Bellevue，对适应性信号灯的转变是一个在欢迎新方法的价值方面的榜样)”可推知，从Bellevue的成功中可以得出，尝试新事物是值得的。故选A项。

【解析】这是一篇说明文。《神经病学》杂志发布的一则研究显示，需要大量的分析思考、细致规划和其他管理技能有挑战性的工作，有可能会帮助你的大脑随着年龄的增长而保持敏锐。
28.细节理解题。根据第二段第一句“ResearchersfromtheUniversityofLeipziginGermanygatheredmorethan1,000retiredworkerswhowereoverage75andassessedthevolunteers’memoryandthinkingskillsthroughabatteryoftests.(来自德国莱比锡大学的研究人员召集了1000多名75岁以上的退休老人，并通过一系列的测试对他们的记忆力和思维能力进行了评估。)”可知，科学家让志愿者做测试是为了测试他们的心智能力。故选D项。
29.推理判断题。根据第四段中FranciscaThen说的话“Thisworksjustlikephysicalexercise,(这就像体育锻炼一样有效。)”及接下来进一步的解释“长跑后人就会感到痛苦和疲惫，但它确实能强身健体。工作一天下来会感到劳累，但这也使你的大脑处于健康状态”可知，FranciscaThen是通过与“身体锻炼”作比较来解释他的发现的。故选B项。
