eknowthatitsinhabitantswereveryresourceful:abrokenpotwasrecycledtomakeaspindlewhorl,andarazorhasbeenheavilysharp

enedtolengthenitslife.”可知，从斯特普尔豪斯的废弃物中我们了解到它的居民是充满智慧的：一个破碎的罐子被回收用来制作一个纺锤轮，一把剃刀被磨快来延长它的使用寿命，由此可知，斯特普尔豪斯被遗弃的物品有价值是因为它们承载了过去生活的信息（从它们我们

能够了解过去人们生活的一些情况），故D项正确。13.A细节理解题。根据第四段中的“Forcenturies,fishingbasketsinGuamweremadeofcoconutleavesbuthereGuerrerou

sedplasticwrappingfoundonhislocalbeach.”可知，几个世纪以来，关岛的捕鱼篮都是用椰叶做的，但格雷罗在这里使用的是当地海滩上发现的塑料包装，也就是说格雷罗通过改变制作材料改变了传统的捕鱼篮，故A项正确。14.C细节理解题。根

据第二段中的“OndisplayinRoom3,Disposable?exhibitsagroupofobjects:findsfromStapleHowe,asettlementsometimebetween700BCand450BC.”可知，一次性？展览展出了在斯特普尔豪斯发

现的、公元前700年到公元前450年之间的人类定居点的一组废弃物品；再根据第三段中的“ThesecondhalfoftheDisposable?displaysthehumanimpactofmodemwasteinthePacificIslandnations.”可知，一次性？展览的后半

部分展示现代垃圾对太平洋岛国居民的影响，由此可知，一次性？展览展示了古代和现代物品，故C项正确。15.D细节理解题。根据倒数第二段中的“Theplasticcrisiscannotbelefttoindividualsorcommunitiesandwilltakeaco

ncertedinternationaleffortbygovernmentsacrosstheglobe.”可知，作者认为解决塑料危机不能只靠个人和社区，需要全球各国政府共同努力，故D项正确。Passage4Timemagazinelist

垃圾场运行。人类必须共同努力，减少塑料的使用，并修复我们的废物造成的破坏。12.B词句猜测题。根据第二段中的Everyyear,morethan8milliontonsofplasticsendupinouroceans,according

totheUNEnvironmentProgramme.(根据联合国环境规划署的数据，每年有超过800万吨的塑料最终进入我们的海洋。)及match前的theweightofoceanplastics(海洋塑料的重量)及

其后的theweightofallthefishinouroceans(我们海洋中所有鱼类的重量)可知每年都有许多的塑料进入海洋，根据逻辑推理知海洋塑料的重量将会与鱼类的重量相等，可推测知match在此

处意为“相等”，故选B项。13.A细节理解题。根据第二段中的Itispredictedthattheweightofoceanplasticswillmatchtheweightofallthefishinouroceansby2050.Topreventth

isfromhappening,in2013SlatcreatedtheOceanCleanup(据预测，到2050年，海洋塑料的重量将与我们海洋中所有鱼类的重量相匹配。为防止这种情况，Slat创立了TheOceanCleanup)可知Slat创立TheOceanCleanup是为了收集

海洋塑料垃圾，防止塑料重量与鱼类重量相等的状况发生。故选A项。14.D细节理解题。根据第三段中的adevicecalledSystem001/BsuccessfullystartedgatheringplasticsonOctober2,2019.(一种名为System001/

B的设备于2019年10月2日成功开始收集塑料)可知System001/B是一种已经投入使用的海洋清洁设备。故选D项。15.C推理判断题。根据最后一段中的itisundeniablethathumanity

mustworktogethertoreduceourplasticuseandrepairthedamageourwastehascaused(不可否认的是，人类必须共同努力减少塑料的使用并修复我们的废物造成的破坏。)可知Slat想传达出人们应该

努力减少塑料污染。故选C项。Passage6Aroundtheworld,bananaplantsaredyingatanalarmingrate.TheyarebeingattackedbyaformofPanamadiseasecalledTropicalRace4(TR4).TR4is

在以惊人的速度死亡。它们正遭受一种巴拿马疾病的攻击，这种疾病被称为TR4。文章说明了TR4对拉丁美洲和加勒比地区香蕉种植地的影响，以及说明了导致香蕉处于危险之中的原因，和历史上香蕉曾面临过的危机。8.D细节理解题。根据第一段中Itinfectsbananap

lantsthroughtherootsandmovesintothestemswhereitpreventswaterandnutritionfromreachingtheplants‟leaves.Theplant

sturnyellow,andthentheydryupanddie.可知，它通过根部感染香蕉植物，并进入茎部，在那里它阻止水分和营养到达植物的叶子。植物变黄，然后枯萎死亡。由此可知，TR4阻碍了香蕉植物的营养

运输，从而杀死了香蕉植物。故选D。9.A细节理解题。根据第二段中ItcantakesixmonthstoayearforfarmerstospotTR4inafieldofbananaplants.Byth

en,it'shardtotreatthedisease.可知，农民们需要6个月到一年的时间才能在一片香蕉地里发现TR4。到那时，就很难治疗这种疾病了。由此可知，对抗TR4最基本的是尽快找到TR4。故选A。10.B词义猜

测题。根据上文Butalackofdiversityisnotgoodfornature.AllCavendishbananasaregeneticallythesame,so,whenadiseasesuchasTR

4strikes,theyareallequally可知，缺乏多样性对自然是不利的。所有Cavendish香蕉的基因都是一样的，所以当TR4这样的疾病来袭时，它们都同样脆弱。故划线单词意思为“脆弱的，容易受伤害的”。故选

B。11.B细节理解题。根据倒数第二段中Partoftheproblemisthat99%ofbananasexportedareofthesamevariety:Cavendish.可知，在问题的部分原因在于，出口的香蕉99%都是同一品种：Cavendish香蕉，

这种香蕉能抵抗巴拿马病。由此可知，几乎所有出口的香蕉都是Cavendish香蕉。故选B。Passage7WhenpeoplethinkaboutBritishmusic,forthemostparttheythinkaboutthe60sor70swiththelikesofThe

最后一句Whenitmovesunsteadilyacrosssomethingthatmightkillit,itwillstandstill.可知，当它摇摇晃晃地穿过可能会杀死它的东西时，它会静止不动。由此可推知，当鸮鹦鹉

面对危险时，它不能做出积极的反应，这对鸮鹦鹉的生存来说是一种威胁。故选D。9.A细节理解题。根据第三段中Thescientists'patienceisfinallyrewarded.Therimuwasinfruitthisyear,andmorethan80c

hickshatched,makingthisthebestbreedingseasononrecord.可知，科学家的耐心终于得到了回报。今年的柚木结果了，80多只雏鸟破壳而出，这是有记录以来最好的繁殖季节。由此可知，科学

家们的耐心得到了回报，今年有80多只雏鸟破壳而出。故选A。10.A细节理解题。根据第四段中Anotherdangertothekakapoisalackofgeneticdiversity.Thisisonere

一项研究表明，与传统药物相比，市面上不断推出的新药大部分并不具有新的疗效。作者分析其中原因并指出，因为相关机构的要求，加上新药耗时费钱，因此药品公司干脆转向研究罕见病的药品，而不是对已有的药品进行改良。12.A细节理解题。根据文章

第二段中“heauthorslookedat216drugsapprovedbetween2011and2017；152werenewlydeveloped,and64wereexistingmedicineapprovedfornewuses.Only25%offere

damajoradvantageovertheestablishedtreatment,andfully58%hadnoconfirmedaddedbenefittoreducesymptomsorimprovehealth-relatedq

ualityoflife.”可知，英国《医学期刊》的一篇报道对2011到2017年上市的药品的研究发现，其中58%的新药与已有的药物相比，没有任何得到证实的新增加的药效。故最近的报告传达了许多新药没有改进的优势的信息。结合选项，故选A

。13.B细节理解题。根据文章第三段中“Suchorganizations,knownashealthtechnologyassessment(HTA)agencies,workalittledifferentlyintheUS,say

sSeanTunis，aresearcherinBaltimore:“Ifpayersthinkanewdrugisn'tbetterthananexistingdrug，theseagencieswillrequire.tha

thospitalstrythecheaperdrugfirst.”可知，美国的卫生技术评估机构的功能与德国不同，如果付费方（病人）认为某种新药不比已有的药品更好，那么“他们（评估机构）就会要求医院先试

用便宜一些的药品"，故选B。14.D推理判断题。根据文章倒数第二段中“Germany'sHTAdemandstrialstoprovethatanewtreatmentbeatstheexistingstanda

现有标准。这并不总是可行的一件事，这样的研究可能是昂贵和耗时的，没有成功的保证。其次，它可以阻止公司尝试开发新的替代品。这已经发生了。药物开发人员越来越关注那些没有好的治疗方法可与之竞争的领域，例如罕见的疾病）可知，德国卫生技术

评估机构要求有药物试验来证实改良后的新药比原先的药品更好，这需要大量的金钱和时间。由此可以推断出，德国HTA的试验的缺点是不利于公司对已有药品进行提升。结合选项，故选D。15.C标题判断题。全文讲述药品研发的窘境：传统药物的更新未必有新的

疗效，即使有新疗效，相关机构的要求使这个更新过程漫长而且费用高，于是很多药企干脆转向研究罕见病的新药，这就使已有药品的更新面临窘境。故C项ADilemmawithNewDrugAlternatives“新药物的两难选择”作为标题，符合题

意。故选C。Passage13Thecombinationofdayandnightextremeheatwillonlygetmorefrequent-andhotter-inthefuture.There‟snothinglikethecoolre

文。一项新的研究表明，一种新的趋势正在上升——白天极度炎热，夜晚极度炎热。研究表明，持续变暖会使情况变得更糟，白天和晚上的极端天气不仅仅是舒适的问题，它们也是对人类健康和自然景观的潜在威胁。其他研究表明，长期

暴露在极端温度下会使中暑或其他与热有关的疾病的几率增加，并会影响植物的生长。12.D细节理解题。根据第四段中thesecompoundextremeswillhappenaboutfourtimesmorefreque
