答案：A

【答案解析】

本文是说明文。文章通过例子讲述了航空旅行与气候变化的关系，倡导减少航空旅行。

【详解】

推理判断题。根据第一段“Tyersusedtoflyalot.Hechangedhismindwhenhereadareport

warningthatextraordinarysocietalchangeswouldbeneededifhumanitywantedtokeepglobal

warmingto1.5℃abovepre-industriallevels.（泰尔斯过去经常乘坐飞机。当他读到一份警

告报告，如果人类想要将全球变暖保持高于工业前水平1.5。，就需要非凡的社会变革）''

可知，泰尔斯之前总坐飞机，但当他读到人类要想俣持到工业化以前的全球变暖温度，

得需要做点社会性改变，他改坐火车，因此推断他乘坐火车去上海是因为他想要为减少

排放作贡献。故选B。

答案：D

【答案解析】

这是一篇说明文。本文主要介绍了科学家为应对气候变化搜集野生作物种子的经过，以

及他们的发现。

【详解】

细节理解题。根据第一段的“theyhadtofaceblood-suckingcreaturesandfiercetigers.

Sometimes,theyhadtouseelephantsfortransportationbecausetheycouldn'tfindanyother

meansoftransportation.（他们不得不面对吸血的生物和凶猛的老虎。有时，他们不得不

用大象来运输，因为他们找不到其他的交通工具。）''可知，在搜集种子的过程中科学家

们遇到了很多危险和困难。故选B。

【详解】

推理判断题。根据第五段的“Somerelativesofwidelygrowncropshavedevelopedsothey

cansurviveusualandsevereconditionssuchaslowrainfall,flooding,extremetemperatures

andpoorsoils.（一些广为种植的作物的同类已经发育成熟，因此它们可以在普通和恶劣

的条件下生存，如少雨、洪水、极端温度和贫瘠的土壤。）“可推知，它们中的有些作物

已经适应了极端气候。故选B。

【详解】

推理判断题。根据最后一段的“Somecropsarethreatenedbecauseofdestructionofforests,

conflictandexpandedcities.（一些农作物受到威胁是因为森林破坏、冲突和城市扩

张。）”可推知，人类活动对某些作物有消极影响。故选D。

【详解】

主旨大意题。根据文章的主要内容，尤其第一段的“Morethan100scientiststraveledto

farawayplacestocollectwildcropseedsinanefforttohelpbattleclimatechange.（100多名

科学家前往遥远的地方搜集野生作物的种子，以帮助应对气候变化）”可知，本文主要介

绍了科学家为应对气候变化搜集野生作物种子的经过，以及他们的发现。故D项“科学

家们为应对气候变化收集野生种子”适合作为本文的最佳标题。故选Do

答案：C

【答案解析】

本文是记叙文。文章主要介绍了印度女孩儿Basu如何从无知的小孩成长为致力于森林保

护的青年学者的故事。

【详解】

推理判断题。根据第一段内容“Backinheryouth,shehadtobetaughttheimportanceof

nature.Sheusedtodestroynestsofbirdsjustforfun.Once,hermothercaughtherandforced

hertofindtheeggsandreplacethenest.Withaheavyheart,thegirlrealizedshehaddone

巢。有一次，她的母亲抓住了她，告诉她必须找到鸟蛋，并替换了巢。满怀沉重的心

情,女孩意识到自己做了一件可怕的事）”和第二段的“Livinginthecountryside,shespent

heryouthstudyingantsbeforearain,watchingsunbirds,countingfirefliesandwatching

seedlings（幼苗）grow.（她生活在乡下，年轻时曾在下雨前研究蚂蚁，观看太阳鸟，数萤火

虫，看着幼苗生长）”可推断，随着Basu对大自然的了解，她对自然的热爱越来越大。故

选B。

【详解】

细节理解题。根据第四段内容“IFSAisaglobalorganizationthatconnectsforestrystudents

totheirpeerandforest-relatedorganizationsandpolicyplatform,enablingthemtoparticipate

inforestryactivities.TheyouthjoiningIFSAareencouragedtoachieveitsvision——tohaveall

thepeopleandsocietiesondieearthrecognizethefullworthofforestsandfullyundeistand

相关的组织和政策平台,可让学生参加林业活动。鼓励加入IFSA的青年们履行使命——

让地球上所有的人们和社会都认识到森林的全部价值，并充分了解森林）''可知，IFSA旨

在召集林业专业的学生和相关专业人士及组织开展活动，以提高人类保护森林的意识。

故选D。

【详解】

细节理解题。根据第二段第一句"ThisisjustonewaythatBasu'sparentsshapedher

understandingandappreciationofnature4这只是Basu的父母塑造她对自然的理解和欣赏的

一种方式）“可知，Basu的父母帮助她建立了对自然的理解和欣赏。故选D。

forestryorganization.（来自印度的OindrilaBasu,现年25岁,是全球林'业组织的重要成

员广和下文内容可知，本文主要介绍了印度女孩儿Basu如何从无知的小孩成长为致力于

森林保护的青年学者的故事。文章着重她的成长过程，而非实际成就，因此C项

"Basu：一个致力于森林保护的森林天使''更合适。故选C。

答案：B

【答案解析】

这是一篇记叙文。文章主要讲述几名青少年为保护环境所做的努力。

【详解】

词句猜测题。根据划线词所在句"Justinsaidthatfrogsarean"indicatorspecies”which

meansthatwhentheirhabitatisthreatened,theyshowsignsofillnessearlierthanotheranimals.

（Justin说，青蛙是一种“指示物种”，这意味着当它们的栖息地受到威胁时，它们比其他

动物更早出现疾病迹象。）”中修饰indicatorspecies的定语从句可知,“指示物种”指的

是能够通过自身状况去反映环境变化的物种，所以D选项“Creaturesmonitoring

environmentalchanges.（监测环境变化的生物。）”解释了该词，符合题意。故选D项。

【详解】

细节理解题。根据AadyaJoshi,16,fromMumbai,India部分的“NowAadyaisleadingthe

RightGreen,anorganizationshefoundedtoeducatepeopleaboutgrowingnativeplantsand

maintaininghealthyecosystems.（Aadya正在领导她创立的“绿色正义”组织，该组

织旨在教育人们如何种植本地植物和维护健康的生态系统。）“可知，Aadya认为修复生

态系统的适当的方式是种植当地的指物。故选B项。

【详解】

细节理解题。根据XavierBaquero-Iglesias,11,fromNaples,Florida部分的“Thenhe

inventedSoleXTurfwhichusestheheatfromAstroturftomakeelectricity.Xaviersayshis

inventioncreateselectricityinawaythafslessharmfiiltotheenvironment（然后他发明了太

阳能草皮，利用人造草皮的热量来发电。Xavier表示，他的发明以一种对环境危害较小

的方式发电。）“可知，Xavier的发明其价值在于它能够以无污染的方式发电。故选D

项。

【详解】

主旨大意题。根据文章第一段“Manypeople,includingkids,protecttheEarthallyearlong.

Readaboutsomeinspiringstories,thendecidehowyouwillmakeadifference.（许多人，包

括孩子，一整年都在保护地球。阅读一些鼓舞人心的故事，然后决定你将如何有所作

为。）''和全文内容可知，文章主要讲述几名青少年为保护环境所做的努力。所以B选

项“KidHeroesforthePlanet（保护地球的儿童英雄）”概括了文章主旨，适合作为文章标

题。故选B项。

【答案解析】

这是一篇说明文。文章介绍了海藻糖可用让血液得以长期储存这一科学发现。

【详解】

词句猜测题。第二自然段“JonathanKopechek,abioengineerfromUniversityofLouisville

sayssuspensiontoregularblooddonationsduetoCOVID-19hasputstressonthebloodsupply,

andthepandemicunderscorestheneedformorereliablelong-termstoragemethods.（路易斯维

尔大学生物工程师JonathanKopechek表示，由于C0VID-19,暂停定期献血给血液供应

带来了压力，这场大流行突显出对更可靠的长期储存方法的需求）”中讲到COVID-19造

成暂停定期献血（suspensiontoregularblooddonations）,结合前文可推知，我们现有的血

液储存方式存在缺陷，容易受到影响，我们需要更可靠的血液储存方式。这是在COVID-

19大流行时期暴露出来的问题，也就是说COVID-19大流行突显出这一需求的迫切性

（underscorestheneed）,underscores可以理解为“突显,强调故选C项。

【详解】

细节理解题。根据第三自然段“GoodnewsisthatKopechek^teamhasdevelopedamethod

ofpreservingbloodsoitcanbestoredinadehydrated（脱水的）stateatroomtemperature.To

doso,theyturnedtoasugarcalledtrehalose（海藻糖）（好消息是，Kopechek的团队已经开发

了一种保存血液的方法，这样它就可以在室温下以脱水状态保存。为了做到这一点，他

们转向一种叫做海藻糖的糖）”可知，科学家发现海藻糖有助于血液的长期保存。故选D

项。

【详解】

细节理解题。根据第五自然段内容可知用海藻糖储存血液的顺序是“theydrilledtemporary

holesinthecellmembranes（他们在细胞膜上钻了一些临时的洞）"，"havesufficient

trehaloseonboththeinsideandtheoutsideofthecell（细胞内夕卜都有足够的海藻糖吗）”,

“thebloodcouldbedriedandmadeintoapowder（血液可以被干燥成粉末）"和"wecan

rehydratethebloodandhaveitreturnbacktonormal（我们可以给血液补充水分让它恢复正

常）故选A项。

【详解】

主旨大意题。根据第二自然提出的问题“thepandemicunderscorestheneedformorereliable

long-termstoragemethods.（这场大流行突显出对更可靠的长期储存方法的需求）”和下文科

学家利用海藻糖来储存血液可知，本文主要介绍了海藻糖可用让血液得以长期储存这一

科学发现。故选B项。
