参考答案【答案】1．C2．D3．D【分析】本文是应用文。文章通过三位不同STEM（科学、技术、工程和数学）领域专业人士的自述，介绍了他们在“ScienceforEveryone”这一新展览中的互动体验。【解析】1．细节理解题。根据BECCAPEIXOTTO所对应的表格中“Ilovedvisitingmygrandparents’oldfarmhouseinVermontandfindingthingsthepreviousownershadleftbehindintheearly1800s.Icametoarchaeologyinaprettyroundaboutway.Istartedcollegestudyingengineering.WhenItookmyfirstarchaeologycourse,itwaslikealightbulbturnedon!It’sexcitingtofindanartifactburiedforhundredsofyearsandthinkaboutthelifeofthepersonwhohelditlast.(我喜欢去拜访祖父母在佛蒙特州的老农舍，寻找上世纪初主人留下的东西。我走了一条相当曲折的路才接触到考古学。我开始在大学学习工程学。当我第一次上考古课的时候，就像亮了灯一样！找到一件埋藏了几百年的文物，想想最后保管它的人的生活，真是令人兴奋)”可知，BeccaPeixotto在大学期间修的一门课让她对考古学感兴趣。故选C项。2．细节理解题。根据JESSICAFAGERSTROM所对应的表格中“Ihelptreatpatientswhohavecancer,usingradiation.Myjobistomakesurethattheradiationisdeliveredsafelyandeffectively.(我帮助治疗癌症患者，使用放射疗法。我的工作是确保辐射安全有效地输送出去)”可知，JessicaFagerstrom通过安全有效地传递辐射来帮助病人。故选D项。3．细节理解题。根据BECCAPEIXOTTO中“It’sexcitingtofindanartifactburiedforhundredsofyearsandthinkaboutthelifeofthepersonwhohelditlast.(找到一件埋藏了几百年的文物，想想最后保管它的人的生活，真是令人兴奋)”，JESSICAFAGERSTROM中“Ihelptreatpatientswhohavecancer,usingradiation.Myjobistomakesurethattheradiationisdeliveredsafelyandeffectively.(我帮助治疗癌症患者，使用放射疗法。我的工作是确保辐射安全有效地输送出去)”以及GRACIEERMI中“Iwritecodetoaidwildlifeconservation.(我写代码是为了保护野生动物)”可知，这三个人的共同点是他们运用自己的技能以各种方式造福社会。故选D项。【答案】4．D5．A6．B7．C【分析】这是一篇新闻报道。文章报道了龙海芬在支教志愿者的鼓励和帮助下如愿上了大学的事迹。【解析】4．细节理解题。根据第二段“InJuly2002,XuBenyu,thenajuniorstudentatHZAU,volunteeredtoteachintheruralareasofGuizhou.Thefollowingyear,hegaveuppostgraduatestudiesandreturnedthere,teachingattwoschoolsfortwoyears,includingLong’selementaryschool.In2005,HZAUestablishedthe“BenyuVolunteerServiceTeam”,engagingstudentsannuallytocontinueprovidingeducationalsupport.(2002年7月，华中农业大学大三学生徐本禹到贵州农村支教。第二年，他放弃了研究生学业，回到那里，在两所学校任教两年，其中包括朗的小学。2005年，华中农业大学成立了“本禹志愿者服务队”，每年组织学生继续提供教育支持)”提到，徐本禹2002年赴贵州支教，次年放弃读研并返回贵州任教两年（2003-2005）。因此他在贵州的志愿服务总时长超过两年，故选D。5．细节理解题。根据第三段“In2017,the19thvolunteergroup,includingCaoYuanyuanandLiZongqing,arrivedatLong’sschool,WeiminElementarySchool,whichhad174studentsfromkindergartentosixthgradebutonlysixclassrooms.Theschoolwasseverelyunderstaffed.CaohadtoteachfoursubjectswhileLimanaged23classesperweek.(2017年，包括曹媛媛和李宗庆在内的第19批志愿者抵达龙的学校——为民小学，该校有174名从幼儿园到六年级的学生，但只有六间教室。学校人手严重不足。曹必须教四门课，而李每周要教23门课)”可知，龙海芬的学校教师严重短缺，急需教师。故选A。6．细节理解题。根据第四段“ThevolunteersnotonlytaughtknowledgetoLongbutalsodevelopedherpersonalgrowth.Theyencouragedhertodeliverspeechesattheschool’sflag-raisingceremonies,helpingtobuildherconfidence.Theyalsobroadenedherviewsbeyondthemountains.(志愿者们不仅向龙传授知识，还促进了她的个人成长。他们鼓励她在学校的升旗仪式上发表演讲，帮助她建立信心。他们还拓宽了她的视野，使她超越了山脉)”和第五段“Unfortunately,in2020,herfatherwasinvolvedinacaraccident,placingthefamilyinfinancialdifficulty.Hearingthis,thevolunteersquicklyraisedenoughmoney,ensuringLong’sfollowingeducation.Alltheseeffortspaidoff.LongwasadmittedtoHZAU.(不幸的是，在2020年，她的父亲遭遇了一场车祸，使这个家庭陷入经济困境。听到这个消息，志愿者们很快筹集到了足够的资金，确保了龙的后续教育。所有这些努力都得到了回报。龙被杭州大学录取了)”等内容可知，志愿者不仅提供知识教育，还通过演讲训练、组织北京游学活动帮助龙海芬建立信心、拓宽视野，并在其家庭困难时资助她的学业。在志愿者的鼓励和帮助下，龙海芬如愿上了大学。故选B。7．推理判断题。根据最后一段“Lookingahead,Longisexcitedtowelcomecollegelife.Shehopestogivebacktosocietyandbecomeavolunteerlikeherteachersandhelpmorechildrenplanttheseedstogrowandthrive.(展望未来，龙很兴奋地迎接大学生活。她希望回馈社会，像她的老师一样成为一名志愿者，帮助更多的孩子播下成长和茁壮成长的种子)”可知，龙海芬希望回馈社会，成为像她的老师们一样的志愿者。故选C。【答案】8．D9．D10．B11．C【分析】这是一篇说明文。本文主要介绍了人造食用染料，尤其是RedNo.40可能会导致许多健康问题，并介绍了一些关于人造食用染料安全性的研究结果。【解析】8．推理判断题。根据第二段关键句“Agrowingbodyofresearchhaslinkedartificialfooddyes,especiallyRedNo.40,tomanyhealthissues.“Thereisdatainanimalsthatsomeofthesedyesmaycausecancer,”Alansays.(越来越多的研究将人造食用染料，尤其是RedNo.40，与许多健康问题联系起来。艾伦说：“动物体内有数据表明，这些染料中的一些可能会导致癌症。”)”可知，文章前三段主要介绍了人造食用染料，重点介绍了RedNo.40会导致许多健康问题，数据表明这些染料中的一些可能会导致癌症，由此可知，从前三段可以推断出RedNo.40可能会导致健康问题。故选D项。9．推理判断题。根据“challenge”后句“childrenweregivendyesandobservedtoseehowtheyreactedafterward(给孩子们服用染料，观察他们之后的反应)”和“In16ofthe25studiesofthereport,therewasalinkbetweenchildrentakingthedyesandhavinghyperactivityandotherneurobehavioral(神经行为学的)problemsafterward.(在该报告的25项研究中，有16项研究表明，服用染料的儿童与多动和其他神经行为问题之间存在联系。)”可知，给孩子们服用染料会导致多动和其他神经行为问题，由此可知，这一行为对孩子健康有害，科学家们不愿意在儿童身上做这样的实验，所以这是一个“挑战性研究”，由此可知，第3段中使用“挑战”一词是为了表明科学家们不愿意在儿童身上做这样的实验。故选D项。10．推理判断题。根据最后一段关键句““Thecancerconcernsmostlyoriginatefromanimalstudiesthatoftenuseverylargeexperimentaldoses,”hesays.“Forseveralofthosedyes,theevidenceofaharmfuleffecthasnotbeenconclusive.”(他说：“癌症的担忧主要源于动物研究，这些研究通常使用非常大的实验剂量。”“对于其中几种染料，有害影响的证据尚未得出结论。”)”可知，DieGonzalez认为几种染料是否有害，尚未得出准确证据，由此可知，他的话表明关于人造食用色素对人体的研究还不够，为了得出准确证据，还需要进一步研究。故选B项。11．主旨大意题。通读全文，结合第二段关键句“Agrowingbodyofresearchhaslinkedartificialfooddyes,especiallyRedNo.40,tomanyhealthissues.(越来越多的研究将人造食用染料，尤其是RedNo.40，与许多健康问题联系起来。)”可知，本文主要介绍了人造食用染料，尤其是RedNo.40可能会导致许多健康问题，并介绍了一些关于人造食用染料安全性的研究结果，由此可知，本文主要介绍了关于人工食用染料安全性的研究。故选C项。【答案】12．A13．D14．C15．B【分析】本文是新闻报道。文章报道了中国在月球上发现了一种罕见的月球晶体，并介绍了这种晶体的特性、发现过程以及其潜在的应用价值，特别是在提供无限能源方面的可能性。【解析】12．细节理解题。根据倒数第二段“Oneoftheprimaryingredientsfoundinthiscrystalishelium-3,whichscientistsbelievemayprovideastablefuelsourcefornuclearfusionreactors.(在这种晶体中发现的主要成分之一是氦-3，科学家认为它可以为核聚变反应堆提供稳定的燃料来源)”可知，氦-3为核聚变反应堆提供了一种潜在的稳定燃料来源，所以很重要。故选A项。13．细节理解题。根据第二段“Thecrystalwasfoundinlunarbasalt(玄武岩)smallpiecescollectedfromthemoonin2020andmakesChinathethirdcountrytodiscoveranewlunarmineral,behindtheUSandtheformerSovietUnion.TheChinesemoonmissionlandedinOceanusProcellaruminDecember2020andhasbeenthefirstlunarsamplereturnmissionsincethe1970s.(这种晶体是在2020年从月球收集的小块玄武岩中发现的，这使中国成为继美国和前苏联之后第三个发现月球新矿物的国家。中国的月球任务于2020年12月在Procellarum海洋着陆，这是自20世纪70年代以来的第一次月球样本返回任务)”可知，月球晶体是从月球上采集的第一个样本。故选D项。14．词句猜测题。根据前文“TheelementisincrediblyrareonEarth(这种元素在地球上非常罕见)”以及but转折可知，这种元素在地球上非常罕见，但在月球上似乎相当普遍，推知prevalent应是“普遍的”之意，和C项意思相近。故选C项。15．细节理解题。根据最后一段“Althoughitistooearlyforscientiststohavemadeanyfinancialestimatesonsuchafuelsource,itwillundoubtedlybeextremelycostly:Thereis,ofcourse,thematterofbringingthecrystalsbackfromthemoon,especiallyinthelargeamountsthatareneededtofuelfusionreactors.(尽管科学家们对这种燃料来源进行任何财务估计还为时过早，但毫无疑问，它将极其昂贵：当然，从月球带回晶体是一个问题，特别是需要大量的晶体来为聚变反应堆提供燃料)”可知，因为需要从月球上获取大量的晶体，所以使用氦-3作为燃料是非常昂贵的。故选B项。【答案】16．E17．F18．D19．C20．A【分析】本文是说明文。文章主要介绍了如何摆脱生活中的困境。【解析】16．根据上文“Lifeisfilledwithnumerousvictoriesanddownfalls.(人生充满了无数的胜利和失败。)”和下文“ Here’showyoucancreateanewchapterinyourlife.（以下是你如何在生活中开创新篇章的方法。）”可知，上文告诉我们人生充满了无数的胜利和失败，下文讲述处理方法，E项意为“重要的是你如何处理每种情况。”选项承上启下，面对人生中的胜利和失败，重要的是你如何处理每种情况。故选E。17．根据上文“Whatyoucandointhiskindofsituationisdrawamentalline.(在这种情况下，你能做的就是画一条心理线。)”可知，上文告诉我们面对困境时可以画一条心理线，F项意为“这条线将帮助你标记未来的决定。”，选项能够承接上文，介绍了心理线的作用，这条线将帮助你标记未来的决定。故选F。18．根据上文“Weneedn’ttrytogothroughallofitonourownbutlearnfromothers.Whenwetalkaboutothers,Irefertothepeoplethatyouareclosewith.(我们不必试图独自完成这一切，而要向别人学习。当我们谈论他人时，我指的是与你关系密切的人。)”可知，上文告诉我们面对困境时可以向关系密切的人学习，D项意为“这些人可能是你的家人和亲密的朋友。”，选项能够承接上文，介绍了关系密切的人可能是你的家人和亲密的朋友。故选D。19．根据上文“Sometimeswemightfeelthatwehavetriedoutsomuchandstillnothingisworkingoutforus.(有时我们可
