1、【正确答案】(1)C;(2)B;(3)C;(1)【导语】丝绸之路国际艺术节在西安举办，以文化对话与合作为主题，多国参与、活动丰富。各国艺术家融合中外艺术元素，创新创作，助力西安打造古今交融的文化名城，增进跨国文化交流。细节理解题。根据第一段“Bycreatingacewheredifferentartistictraditionscanmeet,itcelebratesculturaldiversityandencouragesexchangeacrosscultures.(通过营造一个能让不同艺术流派相互交融的空间，它彰显了文化的多样性，并促进了不同文化之间的交流)”可知，这个节日的主要目的是促进文化交流。(2)细节理解题。根据表格中“Oct.18

Cross-CulturalDanceDialogue

TangWestMarketCenter(10月18日

跨文化舞蹈对话

唐西市场中心)”可知，对于对舞蹈感兴趣的游客来说，唐西市场中心是最佳选择。(3)推理判断题。根据最后一段“Eventsthisyearfeatureawealthofexcitingprogramsthatarewellworthlookingforwardto.ArchitecturestudentsfromItalywillexploreconnectionsbetweenRomangeometryandtraditionalChinesecourtyarddesign.ArtistsfromArgentinawillreinterpretChineseinktechniquesincontemporaryforms.RussianartistswillincorporatetheChinesecharacterFuintotheiroilpaintings,expressinggoodwishesfortheSilkRoadandtheunityitrepresents.Throughsuchevents,thefestivalnotonlyhighlightsartisticdialogueacrosscultures,butalsohelpsXi’anfurtherbuilditsImageasaculturaldestinationwheretheancientandthemodernmeet.(今年的活动安排了众多精彩纷呈的项目，非常值得期待。来自意大利的建筑学学生将探索罗马几何学与中国传统庭院设计之间的联系。来自阿根廷的艺术家将以现代形式重新诠释中国水墨技法。俄罗斯艺术家将在他们的油画中融入汉字“福”，以此表达对丝绸之路以及其所代表的团结的美好祝愿。通过这些活动，该艺术节不仅突显了不同文化之间的艺术交流，还助力西安进一步树立其作为古与今交汇的文化目的地的形象)”可知，中国元素获得了全新的艺术呈现形式。2、【正确答案】(1)A;(2)B;(3)C;(4)D;(1)【导语】文章主要介绍了作者所在研究所通过调整实验室举措减少碳足迹。作者起初因担心科研效率受影响而犹豫，后受一个环保伦理问题启发，加入科研环保项目，并认识到微小改变对科研可持续发展的重要意义。细节理解题。根据原文第二段“Anymeasurethatmightaffectproductivityseemedrisky.(任何可能影响科研效率的措施似乎都存在风险。)”可知，作者起初犹豫是担心他们的科研工作受到影响。(2)推理判断题。根据原文第三段“AudreySabbagh,...onceasked,“Canweconsiderresearchthatisnotethicalfromanenvironmentalpointofviewtobeexcellent?”(AudreySabbagh，……曾发问：“从环境角度来看，我们能否将不符合道德规范的研究视作优秀研究？”)”可知，AudreySabbagh的话暗示了优质的科学研究不能以破坏环境为代价。(3)细节理解题。根据原文第四段“Theresultsshowedthatmorethanhalfoftheemissionsinlaboratorieslikeourscamefromtheproduction,transport,andtechnicalserviceslinkedtolabsuppliesandequipment.(结果显示，像我们这样的实验室，超过一半的排放来自实验物资和设备的生产、运输及相关技术服务。)”可知，实验物资和设备是实验室排放的主要来源。(4)推理判断题。根据原文第五段“Theseweresmallbutpracticalsteps.Overtime,Icametoseethatsustainabilityrequirescarefulbalancing.(这些都是微小却实用的举措。久而久之，我逐渐明白可持续发展需要用心权衡、兼顾各方。)”可知，作者意识到细微的改变能够助力实现科研领域的可持续发展。3、【正确答案】(1)B;(2)D;(3)A;(4)B;(1)【导语】本文介绍如今流行丢弃旧物的现象，介绍修理咖啡馆的兴起、运作方式，并指出其环保意义与暴露的产品设计问题。推理判断题。根据第二段中的“TheideaoriginatedinAmsterdamabout15yearsagoandhassincespreadwidely.SurveysconductedbytheOpenRepairAllianceshowmorethan200,000repairattemptshavebeenrecordedbyover1,100groupsindozensofcountries.Theorganizationalsoestimatesthatmorethan4,000repaircommunitiesmaynowbeactivearoundtheworld.(这个想法大约15年前起源于阿姆斯特丹，此后广泛传播。开放维修联盟的调查显示，数十个国家的1100多个组织记录了超过20万次维修尝试。该组织估计，目前全球可能有超过4000个维修社区在运行)”可知，作者列举大量数据，是为了说明修理咖啡馆发展速度快、规模不断扩大。(2)细节理解题。根据第三段中的“Ownerslearnhowproductsaredesigned,whytheyfail,andwhatmakessomeitemseasiertorepairthanothers.Forthatreason,RepairCafesshowthatpracticalknowledgecanbesharedandthatmanyproductsaremorerepairablethanpeopleassume.(物品主人能够了解产品的设计原理、损坏原因以及物品维修难易的区别。因此，修理咖啡馆能够实用技能共享，让人们发现很多物品比想象中更好维修)”可知，社区修理活动不仅修理物品，还能让人们学习实用知识，把修理变成学习体验。(3)词句猜测题。根据第四段中的“Inmodernconsumerculture,productsoftenseemopaquetoordinaryusers,asiftheyweresealedboxesnotmeanttobeopened.(在现代消费模式下，产品对普通用户来说往往opaque，就像密封的盒子一样，无法拆开查看内部结构)”可知，此处指产品内部结构看不清、难以了解，opaque意为“不清楚的、难以看懂的”，与unclear意思接近。(4)主旨大意题。通读全文，并结合二小题的分析可知，文章主要讲述修理咖啡馆的兴起、运作模式，不仅可以维修物品、减少浪费，还能发现产品设计弊端、传播实用技能，内涵远超单纯修理物品。B项“修理咖啡馆的兴起：不止于维修物品”能概括文章主旨，适合作标题。故选B。4、【正确答案】(1)C;(2)D;(3)D;(4)A;(1)【导语】文章主要介绍了食盐中广泛含有的钠元素可用于制造钠离子电池，该电池相比锂离子电池耐寒能力更强、低温性能更优越，适合严寒环境下的电动汽车使用，但目前生产成本更高，未来需要在控成本的同时保留低温优势。细节理解题。根据原文第二段“Inlowtemperatures,mostlithium-ionbatterieswoulddeliveronlyaverysmallfractionoftheiroriginalcapacityunlessthepackhasanactiveheatingsystem.(在低温环境下，除非电池组配有主动加热系统，否则大多数锂离子电池只能输出原本容量的极小一部分。)”可知，锂离子电动汽车的动力输出会受到寒冷天气的影响。(2)细节理解题。根据原文第三段“Althoughsodiumionsarelarger,theyformweakerbondswiththeliquidelectrolytethanlithiumdoes.(虽然钠离子体积更大，但它们与液态电解质形成的结合键比锂离子更弱。)”及“Thisallowsthemtomovemuchmoreeasilythanlithiumions,evenwhenthecoldthickenstheelectrolyte.(这使得它们比锂离子移动起来要容易得多，即便低温让电解液变得黏稠时也是如此。)”可知，钠离子与电解质的相互作用比锂离子更微弱，因此在寒冷环境中运转表现更好。(3)推理判断题。根据原文第四段“Laboratorydatasuggestthatat-30℃,thisbatterycandelivernearlythreetimesthedischargepowerofequivalentlithiumironphosphate(LFP)batteries,thecheap,standard-rangebatteriesthatdominatetheEVmarket.(实验数据表明，在零下30摄氏度时，这款电池的放电功率是同等磷酸铁锂电池的近三倍，而磷酸铁锂电池是主导电动汽车市场的平价标准版电池。)”可知，
