学家们开发出的一种系统，利用机器学习能力有效地预测闪电，以减少闪电袭击带来的危害和损失。8．推理判断题。根据第二段中―...thatbetween6,000and24,000peoplearekilledbylightningworldwide

eachyear.Thestrikescanalsocausepoweroutages,destroyproperty,damageelectricalequipmentandstartforestfires.Forthesereasons，climatesci

entistshavelongsoughttodevelopmethodstopredictandcontrollightning.（世界各地每年有6,000至24,000人死于闪电。闪电袭击还可能导致停电、破坏财产、损坏电气设备和引发森林火灾。）‖可知，科协家们想预测、控制闪电

是因为想找到办法，以减少闪电所带来的危害和损失。故选B项。9．细节理解题。根据第四段中―Thedatarelatedtofourmainsurfaceconditions:airpressure,airtemperature,relativehumiditya

ndwindspeed.‖可知，与四个主要表面条件有关的数据有气压、空气温度、相对湿度和风速，没有提到空气污染。故选A项。10．词句猜测题。根据第五段―Theatmosphericdatawasplacedintoamachinelearni

ngalgorithm（算法）,whichcomparedittorecordsoflightningstrikes.（将大气数据输入到机器学习计算法中，随后计算法会将这些数据与闪电袭击记录进行比较。）‖可以

推测，it指代上一句中的theatmosphericdata。故选C项。11．推理判断题。第六段中提到―currentsystemsforgatheringsuchdataareslowandcomplexandrequirecostlycollectione

quipmentlikeradarorsatellites‖，Mostajabi认为目前收集此类数据的系统缓慢而复杂，需要昂贵的雷达或卫星等收集设备；第七段中提到―Ourmethodusesdatathatcanbeobtain

edfromanyweatherstation…Thiswillimprovedatacollectioninveryremoteareasnotcoveredbyradarandsatelliteorinplaceswherecommunicati

onsystemshavebeencut‖,Mostajabi认为他们这种方法使用的数据可以从任何气象站获得，这将改善雷达和卫星未覆盖的非常偏远地区或通信系统被切断的地方的数据收集。因此可以推断，Mostajabi相信他们的系统在数据收集方面比原来的做得更好。故选D项。2.（2020届辽宁

illgetin.可知，他们并没有在运行，但是你仍然可以进入议会。由此判断出，当议会没有正式开会时，他们并没有在运行，但是你仍然可以进入议会。可知，划线句子意思为―当议会没有正式开会的时候‖，故选A。3．细节理解题。根据最后一段中Notonlyisthequalityhigh,butthep

riceislow-onethirdthepriceofBroadway.可知不仅质量好，而且价格便宜——只有百老汇的三分之一。由此可知，伦敦人喜欢戏剧因为他们喜欢便宜的门票。故选B。3.（2020届辽宁省大连市第

许多父母抗议这种话语，但是我们的年轻人实际上并不知道他们是否特别有才华或有成就。很多研究发现，这种夸大的自我判断，而恰恰是在我们最不能胜任某项任务的时候，我们才会对自己的表现给出最慷慨的评价。文章分析了能力不够的人的一些表现，以及摆

脱这种困境的方法。8．词义猜测题。根据后文hisego-puncturingwords.Butlostintheangerandprotestwassomethingwereallyshouldbetakingtoheart:ouryou

ngpeopleactuallyhavenoideawhetherthey'reparticularlytalentedoraccomplishedornot.可知，但在愤怒和抗议中迷失是我们真正应该铭记在心的事情：我们的年轻人实际上并不知道他们是否特别有才华或有

成就。由此判断处出席典礼的父母们——以及互联网上的许多其他父母——都对他的自我伤害言论提出了争议。所以划线短语意思为―对……有争议‖。故选B。9．推理判断题。根据第一段中Inoureagernesstoelevatetheirsel

f-esteem,weforgottoteachthemhowtorealisticallyassesstheirownabilities,acrucialrequirementforgettingbetteratanythingfrommathtomusictosports.

Infact,it'snotjustprivilegedhigh-schoolstudents:wealltendtoviewourselvesasaboveaverage.可知我们急于提升他们的自尊，却忘了教他们如何实际地评估自己的能力，而这是学好数学、音乐、体育等任何学科的关键要

求。事实上，不仅仅是那些享有特权的高中生：我们都倾向于认为自己高于平均水平。由此判断出，在作者看来，年轻人无法合理地定义自己的问题不应该被忽视。故选B。10．细节理解题。根据第三段中Whattheseindividualslacked(inadditiontocle

arlogic,propergrammarandasenseofhumor)was"metacognitiveskill":thecapacitytomonitorhowwellthey'reperforming.可知这些人所缺乏的(

除了清晰的逻辑、正确的语法和幽默感之外)是―元认知技能‖:监控自己表现的能力。由此可知A选项―他们缺乏监控自己表现的能力‖文章提到了；第三段中InDunningandKruger'sstudy,subjectsscoringatthebottomoftheheapontest

soflogic,grammarandhumor"extremelyoverestimated"theirtalents.可知在Dunning和Kruger的研究中，在逻辑、语法和幽默测试中得分最低的受试者―极度高估‖

了自己的才能。由此可知，B选项―‖文章提到了；根据第二段中Peoplewhoareincompetent,hewriteswithco-authorJustinKruger,sufferfroma―dualburden‖

:they'renotgoodatwhattheydo,andtheirineptnesspreventsthemfromrecognizinghowbadtheyare.可知他与合著者JustinKruger写道，

能力不够的人承受着―双重负担‖:他们不擅长自己的工作，而他们的无能使他们无法认识到自己有多糟糕。由此可知C选项―他们往往无法确切知道自己有多糟糕‖文章提到了；只有D选项―他们在测验和考试中不够聪明‖文章没有提到。故选D。11．推理判断题。根据倒数第二段中First,we

canlearntomakehonestcomparisonswithothers.Trainyourselftorecognizeexcellence,evenwhenyouyourselfdon'tpossessit,andcomparewhatyoucandoagai

nstwhattrulyexcellentindividualsareabletoaccomplish(首先，我们可以学会诚实地与他人比较，训练自己认识到优秀，即使你自己没有，并将你能做的和真正优秀的人能完成的进行比较)以及后文Findacriticwhowilltellyouno

tonlyhowpoorlyyou'redoing,butjustwhatitisthatyou'redoingwrong.Usethisexternalfeedbacktofigureoutexactlywhereandwhen

youscrewedup.(找一个批评者，他不仅会告诉你你做得有多糟糕，还会告诉你你做错了什么。利用这些外部反馈，准确地找出你是在何时何地把事情搞砸的。)由此判断出，变得特别的策略意味着我们需要内在的诚实对待自己，外在的诚实对待他人。故选C。4.（2020届辽宁省锦州市高三一模）Je

ellyfishareneitherfishnorjelly.D．Jellyfishhavemanydifferentnames.【答案】8．D9．C10．A11．A【解析】这是一篇说明文。短文介绍了关于水母的一些信息。8．细节理解

题。由第一段―Notonlyaretheyveryfragilecreatures,butmanygiveapainfulsting,andsomeareevendeadly‖可知，水母不仅是非常脆弱的生物，而且很多水母会刺痛人类，有些甚至是致命

的。所以为什么我们不能触摸水母是因为他们可能会伤害人。故选D项。9．细节理解题。由第二段―Choosethewordyoupreferdependingonwhetheryouthinkthejellyfishpacklookslikeagardenofbloomingflow

ersormorelikeafrighteningpackofstingers‖可知，选择你更喜欢的词取决于你认为水母群看起来像一个盛开的花园还是更像一群可怕的刺。所以水母是以它的外表命名的。故选C项。10．细节理解题。由最后段―Jellyfishalsouse

theirmouthsbothforeatingandforwasteremoval‖可知，水母还利用它们的嘴来进食和清除废物。所以我们能从这篇文章中学到嘴是水母重要的器官。故选A项。11．主旨大意题。由第一段，第二段,第三段,第四段―Notonlyaretheyve

y.Jellyfishhavetwomainformsintheirlifecyclethatlookquitedifferentfromeachother.MelanieRoberts,SeniorAquaristatSeaW

orldOrlando,saysthatthelargestjellyfishintheworldisalion‘smanejellyfish‖可知，它们不仅是非常脆弱的生物，而且很多会刺痛你，有些甚至是致命的。这是一个关于水母的

事实，可能会派上用场。水母在它们的生命周期中有两种主要的形态，它们看起来非常不同。奥兰多海洋世界的资深动物检疫员梅勒妮·罗伯茨说，世界上最大的水母是狮鬃水母。所以短文从不同的角度介绍了水母的一些信息。所以短文的最佳标题为―关于水母的几条信息‖。故选A项。5.（2020届辽宁

rable(耐用的)，easilyavailable，andmostimportantly，environmentallysustainable.Theonethingitisnot，istransparent(透明的)‖可知，木头便宜，耐用，容易获得，最重要的是，可持续。

但是它不是透明的。而最后一句提到：由于科学家的努力，已经将―那个特点‖添加到已有的特点单子里了。根据这个语境可以推知，该处应指，科学家们使得木头成为透明的了。―透明‖也成为了它的一个特点。故该画线词应该指D选项：透明。8．细节理解题。根据第二段中的―Thelignin-f

reewoodwasthendippedintoapolymer(聚合物)andbakedatatemperatureof158Fforfourhours‖可知，制造透明木头的过程之一是：将无木质素的木材浸泡在聚

合物中，在158华氏度的温度下烘烤4小时。因此B选项提到的―减少聚合物的量‖和原文不符。故B选项切题。9．推理判断题。根据最后一段中的―Theyarenowexperimentingwithwaystoscaleupthem

anufacturingprocesssothatthetransparentmaterialiscost-effectivetomakeandeasytouse‖可知，现在，他们正在尝试扩大制造工艺，使得透明材料制造起来更加合算，易于使用。由此推知，现在制造透明木头的成本仍然很高，需要降

低成本。故C选项正确。10．主旨大意题。最后一段介绍了透明木头将来在家庭，建筑物，太阳能电池板，环保等方面的应用。由此可知，最后一段主要介绍了透明木头的光明未来。故A选项正确。18.（2020届四川省德阳市高三二诊）He

章主要讲述了听力损失是不可避免的，但年轻时听吵闹的音乐会使情况更糟。要想通过听吵闹音乐来降低听力损失的风险，你需要了解音乐为什么会导致听力损失，以及它是如何造成听力损失的。32．词义猜测题。根据前一句―listeningtoloudmusic

whenyou‘reyoungercanmakeitworse(年轻时听吵闹的音乐会使情况变得更糟)‖中的listeningtoloudmusic为主语，因此本句应是对其进行进一步的描述，―it‖作为不定代词，可指代前文

提及的动作或事物，结合本句―Toreduceyourriskofhearinglossvialoudmusic,learnwhyandhowitcancausehearingloss,andjusthowloudistoolou

d.‖因此可推知本句中it应指前一句―listeningtoloudmusicwhenyou‘reyoungercanmakeitworse(年轻时听吵闹的音乐会使情况变得更糟)‖中的loudmusic。故选D项。33．细节理解题。根据文章第六段内容

―Acutetemporarynoise-inducedhearinglosscanoccurfromattendingaloudconcertorsportingevent,goingtoagunrangewithoutearmuffsor

beingnearanexplosion.(急性暂时性噪音性听力损失可以发生在参加吵闹的音乐会或体育赛事、去没有耳罩的射击场或在爆炸附近。)‖可知参加吵闹的音乐会出现该情况，选项A―Attendingarockconcert.(参加摇滚音乐会。)‖为吵闹音乐会。故选A项。34．细

节理解题。根据文章末尾内容―Foreverythreedecibels,safeexposuretimegetscutinhalf,accordingtotheCDC.At88decibels,youcanonlys

afelylistenforfourhours;at91decibels,justtwohours.(根据美国疾病控制与预防中心的数据，每三分贝，安全暴露时间就会减少一半。在88分贝时，你只能安全地听4个小时;在91分贝时，你只能听两个小时。)‖可知，每增加三分贝

，安全暴露时间就会减少一半，结合后文提及91分贝时，能听两个小时，因此94分贝时，应减少一半时间，即一个小时；97分贝时，再减少一半时间，即能听半个小时。故选B项。35．主旨大意题。文章首段提出了本文的论述中心―Toreduceyourriskofhea

ringlossvialoudmusic,learnwhyandhowitcancausehearingloss,andjusthowloudistooloud.(要想通过大声听音乐来降低听力损失的风险，你需要了解音乐为什么会导致听力损失，以

及它是如何造成听力损失的。)‖可知，本文主要围绕―吵闹音乐与听力损失‖之间进行了阐述，选项A.LoudMusicDamagesHearing(吵闹的音乐损害听力)符合本文主题，可为最佳标题。故选A项。19.（2020届四川省高三第一次统一监测）TheGuidetoFilmFest

天花几个小时查看社交媒体的青少年有患多动症的风险这一发现展开。研究人员通过对参与者进行了为期两年的追踪得出了这一发现。科学家指出频繁的分心会阻碍持续的注意力和组织能力的发展。而两位教授AdamLevent

hal和AndyPrzybylski就此发现表达了自己的看法。12．细节理解题。根据第二段最后一句Aftertwoyears,thosewhohadcheckedtheirphonesthemostoftenweretwiceaslikelyasthosewhocheckedtheleas

toftentoshowsignsofADHD.两年后，那些经常查看手机的人出现多动症症状的几率是那些不经常查看手机的人的两倍。由此可知，研究人员对参与者进行了为期两年的跟踪来进行这项研究的，故选B。13．推理判断题。根据第四段最后一句Wecansaywithconfid

encethatteenswhoareexposedtohigherlevelsofdigitalmediaaresignificantlymorelikelytodevelopADHDsymptomsi

nthefuture可知Leventhal认为频繁接触数字媒体的青少年在未来更有可能出现ADHD症状。由此判断出频繁接触数字媒体会增加ADHD的风险。故选B。14．推理判断题。根据文章最后一句Itisnotclearifteachersorparentswouldrate

thechildrensimilarlyoriftheself-reportedmeasureofdigitalscreenuseisrelatedwitheitheractualbehaviororhigherqualitysurveyi

tems.可知AndyPrzybylski认为目前尚不清楚老师或家长是否会对孩子做出类似的评价等，由此判断出他认为这项研究的发现不够可靠。故选C。15．主旨大意题。根据第一段Teenagerswhochecksocialmediaforseveralhoursadayareattheriskof

developingADHD(多动症),astudyhasconcluded.一项研究表明，每天花几个小时查看社交媒体的青少年有患多动症的风险。以及文章主要内容围绕一项研究表明，每天花几个小时查看社交媒体的青少年有患多动症的风险这一发现展开。所以短文最佳标题为―过度使用社交

媒体可能会增加患多动症的风险‖。故选C。26.（2020届四川省绵阳市高三第三次诊断性考试）ThesloganfortheCulturalHeritageandSustainableDevelopmentFundis"InLoveWith

解析】这是一篇说明文。文章展示了文化遗产和可持续发展基金的标语和标志，并介绍了其背后的设计理念。8．细节理解题。根据第三段第一句―TheChinesecharacterfor‗wind‘andthecharacterfor‗phoenix‘arealmo

stthesame,withjustonestrokedifference.‖可知，标志上绘有―风‖和―凤‖两个汉字的甲骨文，而两个汉字本身也非常相似，这里的设计正是将它们做了一个结合。故选D项。9．细节理解题。根据第四段最后一句―Thisextrao

rdinarycombinationrepresentshowexpertsleadfashion,whichintumleadsculture-andthatcultureisthebasisofcreativity.T

herefore,itrepresentstheimportanceoftraditionalChinesecultureinglobalcreativity.‖可知，两个汉字的结合代表了中国传统文化在全球

创意中的重要作用，这正是设计者选用它们的原因。故选D项。10．推理判断题。根据最后一段第一句―LogoartistSamChungsimilarlyexplainsherdesignprocess‖及整段内容来

看，这里是设计师SamChung在解释她的设计过程，显然她才是真正的设计者。故选A项。11．主旨大意题。全文都在围绕着文化遗产和可持续发展基金的标志展开，讲述其设计理念和表现意图，B选项―CHSDF标志的制作‖是最贴合主题

的。故选B项。27.（2020届四川省遂宁市高三第二次诊断性考试）Inthelastfewyears,companieslikeoBikehavebegunfloodingstreetsinplaceslikeJapanandAustralia

组织LessWalk，从其他国家购买废弃了的共享单车，通过组装，为每天步行很远去学校的学生提供免费自行车。4．细节理解题。根据第二段的LessWalkchangedthisforalockwithakey.Theyalsoaddedasecondseatinthebackofthebik

es,allowingtwochildrentoridetoschoolononebike.Recentlythey‘rereplacingthebike‘sregulartireswithasolidtirethatcan‘tgoflat.可知LessWalk将以前的二维码换成钥匙锁；

在自行车后面增加了一个座位；把自行车的普通轮胎换成了一个实心轮胎。由此可知，LessWalk对自行车做了三个方面的改装。故选B。5．细节理解题。根据第三段的―ButgivingoutthebikestakesalittlelongergiventhatLessWalkwantstomakesur

ethatthebikesgoforfreetothestudentswhoneedthemthemost...‖可知，分发自行车需要更长的时间，是因为LessWalk想要确保自行车送到最需要它们的学生手中，也就是精准捐赠(targetedbikedonation)。本题容易误选A和B。文

章只谈到了从国外运回这些自行车很困难，不是发放是运输困难；文章谈到了缅甸有5000多万人口和900多万学生，但没有说有太多的贫困学生。故选D。6．推理判断题。文章最后一段谈到：Than希望买进多达10万辆自行车，并把这个项目扩展到老挝和柬埔寨等

其他国家。他也希望他能激励―全球朋友‖跟随他，把废弃的自行车投入使用，而不是制造更多的城市垃圾。从这些信息可推知，他是一个很有抱负的商人。故选A。7．主旨大意题。纵观全文可知，全文谈到了Than看到大量的废弃共享单车，就创建Les

sWalk项目，买进大量的单车进行改装，免费发放给每天步行很远去学校的学生。尽管花了钱，但他觉得值得。文中―Despitethecost,thebenefitsitcandeveloparewellworthtrying‖揭示了本文主题。因此C为最佳标题。故选C

Thevarietyoffictionavailabletoreaders.【答案】8．A9．C10．B11．D【解析】这是一篇说明文。介绍了小说翻译人员的地位和作用。8．细节理解题。根据第一段的There‘sawell-knownstoryinth

eworldofliterarytranslatorsaboutthetranslatorwhowasthrilledtoseehisworkappearatgreatlengthinanarticleinapopularm

agazine.和Thearticleagreedwithhisassessmentofthenovelist‘sworksmentioninglongpassagesfromhistranslations.可知，这位翻译家很激动地看到自己的作品出现在一本著名杂志的一

篇文章中。这篇文章通过引用译文中的长篇大论来同意他对这位小说家作品的评价，由此说明他的观点被杂志分享。故选A。9．推理判断题。根据第二段的Thetranslatorsearchedinvainforamentionofhisname.可知，这位翻译家在这篇文

章中寻找他的名字时，却没找到。再根据这段信息―Thetranslator‘sjoyatthecoverage（报道）oftheauthorhelikedwasconsiderablyruinedbythis.‖可知，这位翻译家对他所喜欢的作者的报道所感到的喜悦，

在很大程度上被这一情况破坏了。由此推知他应该感到很郁闷。故选C。10．主旨大意题。根据第三段的However,itisalsotruethatmostreadersthemselvesoperateinexactlythesameway,andforthem

itisalsoasifthetranslatordidn‘texist.Whenpeoplereadatranslationofanovel,theywanttofeeltheyarereadingwhatthenovelist,andnotsome

oneelse,wrote...可知，对于读者来说，就好像译者不存在一样。当他们阅读一本小说的译文时，他们想要感觉到他们读的是小说家写的东西，而不是别人写的。他们不希望被提醒他们不是在阅读原著小说，不希望知道译者是谁，也不关注译者所做的事情。由此可知本段主要在谈读者对译者的一般态度。

故选B。。11．推理判断题。题干上提到globalage，因此本题答案应在最后一段来寻找。文章最后一段谈到：在这个全球化时代，越来越多的小说被翻译成越来越多的语言。读者现在比以往任何时候都能通过阅读翻译小说来体验和了解其他文化。世界其他地方的人们

能够接触到越来越多的小说家的作品。由此推知作者在谈到全球化时，强调了可供读者阅读的小说种类的多样性。故选D。
