【答案】28.A29.B30.C31.D

【解析】

【分析】这是一篇说明文。文章主要介绍一种能够转化可再生能源的新装置，介绍了这一装置的优势

和仍然需要克服的问题。

【28题详解】

推理判断题。根据第一段中“Now,researchershavecreatedsmalllab-scaledevicesthatdobothjobs.If

largerversionsworkaswell,theywouldhelpmakeitpossible-oratleastmoreaffordable—toruntheworld

OnreneWableS.（现在，研究人员已经创造出了同时具备这两种功能的实验室规模的设备。如果更大的

版本也能发挥作用，它们将有助于使世界上使用可再生能源成为可能一一或者至少更经济实惠）”可

推知，这种新装置大规模地投入使用还有待观察。故选A。

【29题详解】

推理判断题。根据第二段uThemarketforsuchtechnologieshasgrownalongwithrenewables:In2007,

solarandwindprovidedjust0.8%ofallpowerintheUnitedStates;in2017,thatnumberwas8%,accordingto

theU.S.EnergyInformationAdministration.Butthedemandforelectricityoftendoesn,tmatchthesupply

inthemiddleoftheday,butnoneatnight,aftermostworkersandstudentsreturnhome.（这种技术的市场已

经随着可再生能源的发展而增长：在2007年，太阳能和风能提供的电力仅占美国全部电力的0.8%；

根据美国能源信息管理局的数据，2017年，这个数字是8%。但对电力的需求往往与太阳能和风能的

供应不匹配。例如，在阳光明媚的加州，太阳能电池板在白天经常生产超过需要的电力，但在晚上，

在大多数工人和学生回家后，却没有电）”可推知，作者在第二段中使用数据和例子是为了强调能源

转化技术的潜在市场。故选B。

【30题详解】

推理判断题。根据第三段中“Butcommercialelectrolyzersandfuelcellsusedifferentcatalyststospeedup

thetworeactions,meaningasingledevicecan,tdobothjobs.Theresearchersmustconquerthis.（但商用电解

槽和燃料电池使用不同的催化剂来加速这两种反应，这意味着一个设备不能同时完成这两项工作。研

究人员必须克服这一点）”可推知，接下来研究人员会主攻这两种反应能够共用的催化剂。故选C。

【31题详解】

推理判断题。根据最后一段中“Still,sheholdstheviewthatbothhernewdeviceandtheonefromthe

O,Hayrelabaresmalllaboratorydemonstrations.Forthetechnologytohaveagreaterimpactinsociety,

researcherswillneedtoscaleupthebutton-sizedevices,aprocessthattypicallyreducesPerformanCe.（尽管

如此，她仍然认为她的新设备和O'Hayre实验室的设备都是小型实验室演示。要让这项技术在社会上

产生更大的影响，研究人员需要扩大按键大小的设备，这一过程通常会降低性能）”可推知，HaiIe对

这个新装置的未来持谨慎的态度。故选D。

D

【解析】

【分析】本文是说明文，从大峡谷的形成、峡谷内天气、大峡谷物种和峡谷探险多个方面介绍了美国

大峡谷。

【32题详解】

推理判断题。根据第二自然段“Therivercaιτieddirtandpiecesofstonethatslowlyateawayatthe

SUlTOUndingrOCk（河水冲走了泥土和碎石，慢慢地侵蚀着周围的岩石）”,uAtthesametime,forces

deepwithinheearthpushedupthesurroundingIand.（与此同时，地底深处的力量把周围的土地抬高了）”

和“Rain,snow,ice,windandplantrootsrubbedatthetopofthisnewcanyon.（雨、雪、冰、风和植物的

根摩擦着这个新峡谷的顶部）”可推知，大峡谷的形成是多种自然力量的结果。故选D项。

【33题详解】

细节理解题。第一自然段“Thecanyons（峡谷）ofAmerica'sSouthwestaredeep,ancientopeningsinthe

earth.TheylookasiftheyformedastheearthSPlit.（美国西南部的峡谷是地球上很深的、古老的裂口。

它们看起来像是地球分裂时形成的）”是引入，根据第二自然段"Fortymillionyearsago,theColorado

Riverbegancuttingthroughtheareaaroundthepresent-dayGrandCanyon.（四千万年前，科罗拉多河开始
