23.Whichsectionofnewspaperisthistextprobablytakenfrom?

A.Finance.B.Science.C.Culture.D.Education.

【答案】21.A22.C23,D

【导语】这是一篇应用文。文章主要介绍了四个学习软件：ABCmouse（开心鼠英语），Homer（Homer学习

软件），HookedonPhonics（美国自然拼读）以及FarFaria（FarFaria学习软件），并对其各自特色和收费进行了

详细说明。

21.细节理解题。根据文章“ABCmouse”部分内容"Thecostafterfreetrialisaround$15permonth.Families

whopurchaseafullyear'ssubscriptioncangetabout70%offtheprice.（免费试用后的费用约为每月15美元。

购买一整年订阅的家庭可以帮你节省原价的70%。）”可知，费用为每月15美元，一年应是“15x12=180”，

同时全年订阅可以帮你节省原价的70%,即，按价格的3折计算，180x（l-70%）=54。故选A项。

22.细节理解题。根据文章“HookedonPhonics”部分内容"Itisoneofthemostpopularbrandsforteachingkids

toread,anditsintegratedsystemmakesitanidealoptionforhomeschoolingstudents.（它是教孩子阅读的最受欢

迎的品牌之一，它的集成系统使它成为在家上学的学生的理想选择。）”可知，HookedonPhonics平台是在

家上学的学生的理想选择。故选C项。

23.推理判断题。通过阅读文章可知，“ABCmouse（开心鼠英语广，"Homer（Homer学习软件）”，“Hookedon

Phonics（美国自然拼读）''以及"FarFaria（FarFaria学习软件）''四个部分分别介绍了该平台的教育信息和收费

方式，由此可推知，该篇文章来自于报纸上的教育专栏。故选D项。

【答案】24.A25.B26.C27.B

【导语】本文是记叙文。它讲述了ParamJaggi从小对拆解事物的热爱，到后来转变为创造事物，特别是

关注环境问题的解决。

24.推理判断题。根据第一段"WhenParamJaggiwasfiveyearsold,hehadapassiontotakethingsaparttosee

whatwasinside.Hestartedwithtoysandevenbrokeacomputer,whichmadehisparentsnottoopleased.（当帕拉

姆・贾吉五岁的时候，他就热衷于拆卸东西看看里面是什么。他从玩具开始，甚至弄坏了一台电脑，这让他

的父母很不高兴户可知，帕拉姆・贾吉从小热衷于拆卸东西看看里面是什么，所以推知他生性好奇。故选A

项。

25.词句猜测题。根据前文“AlthoughJaggi'sparentsinitiallythoughthisexperimentswerejust,aboyhoodfancy,

heremaineddeterminedtomakeadifferencetotheenvironment.（尽管贾吉的父母最初认为他的实验只是男孩

子的一时兴起，但他仍然坚定地想要为环境做出改变）”以及后文“startedsupportinghisdreams（开始支持他的

梦想）”可知，起初，贾吉的父母认为他的实验只是男孩子的一时兴起，后面开始支持他，所以是父母的改

变了主意，推知camearound意为“改变主意”，和B项意思相近。故选B项。

26.推理判断题。根据第二段“Jaggi'sinterestcontinuedashegrewup,buthefocusedmoreonsolvingreal

problems,especiallythoserelatedtotheenvironment.（贾吉的兴趣随着年龄的增长而持续，但他更加专注于解

决现实问题，尤其是与环境相关的问题）”以及第三段“At17,Jaggiwentbeyondhisschoolprojectsand.

co-foundedEcoviate,acompanythatusestechnologytosolveeverydayenergyandenvironmentalproblems.He

plannedtotransformpeople'sideathatgoinggreenisexpensive,bymakingavailableaseriesofaffordable

productsthatareeasytouse.ThroughEcoviate,hedesignedproductsthatcouldcontributetoagreenerfuture.（17

岁时，贾吉超越了学校项目的范畴，与他人共同创立了Ecoviate公司，该公司利用技术解决日常的能源和

环境问题。他计划通过提供一系列易用且价格实惠的产品来改变人们认为环保成本高昂的观念。通过

Ecoviate,他设计了一些有助于创造更绿色未来的产品）”可知，贾吉决心为环境做出改变，他认为绿色是昂

贵的观念需要改变，因此他计划推出一系列价格实惠、易于使用的产品。这表明他开发这些产品的驱动力

是他想要为环境和社会做出改变，即他的渴望有所不同。故选C项。

27.细节理解题。木艮据最后——段“YoungJaggi,nowathird-gradecollegestudentstudyingengineeringand

economics,hasbecomeafamouseco-innovatorandhiscompanyisdevelopingpromisingly.However,Jaggi's

visiontosavetheenvironmentgoesbeyondcreatingproducts.Heplanstolaunchanonlineplatformthrough

名的生态创新者，他的公司发展前景看好。然而，贾吉拯救环境的愿景不仅仅局限于创造产品。他计划通

过氏oviate推出一个在线平台，鼓励对科学和技术感兴趣的年轻学生积极参与创新和发明。学生可以在线

提交科学项目，并谈论他们需要帮助才能使项目成为现实的相关事宜）”可知，贾吉计划通过Ecoviate推出

一个在线平台，鼓励对科学和技术感兴趣的年轻学生积极参与创新和发明。因此，贾吉计划推出在线平台

的目的是为了赋能年轻的发明家，让他们有更多的机会去创新和发明。故选B项。

【导语】本文是一篇说明文。文章主要介绍了聚合物科学家如何致力于解决塑料废物问题，通过重新设计

28.主旨大意题。根据文章第二段"Inaworldsetupfordisposable（一次性的）items,durabilityisnolongera

designfeaturebutratheradesigndrawback.Imagineifhalftheplasticsusedtodaywererecyclablethroughtwice

asmanyprocessesastheyarenow.Alsoconventionalrecyclingrequirescarefulsortingofallthecollected

想象一下，如果今天使用的一半塑料可以通过两倍于现在的过程进行回收。止匕外，传统的回收需要对所有

收集到的材料进行仔细的分类，这对于这么多不同的塑料来说是具有挑战性的。例如，将纸和金属分开并

不需要复杂的技术，但将一个容器和一个牛奶罐中不同的聚烯煌进行分类却很难做到没有偶尔的错误。）”

可知，文章第二段主要讲述的是关于塑料回收的挑战。故选C。

29.细节理解题。根据文章第三段“InastudypublishedinScienceinOctober2023,wedescribedaseriesof

polymerswithonlytwobuildingblocks-onesoftpolymerandonehardpolymer-thatbehavelikepolyolefinsbut

couldbechemicallyrecycled.Connectingtwodifferentpolymersmultipletimesuntiltheyformasingle,long

polyolefintypes.（在2023年10月发表在《科学》杂志上的一项研究中，我们描述了一系列聚合物，它们只

有两种基本成分——一种软聚合物和一种硬聚合物——它们的行为像聚烯烧，但可以化学回收。将两种不

同的聚合物多次连接，直到它们形成一个单一的长分子，就形成了所谓的多嵌段聚合物。通过改变多嵌段

聚合物中每种聚合物的含量，我们的团队生产出了各种各样的材料，其性能涵盖了所有类型的聚烯燃。y

可知，生产多种多嵌段聚合物的关键因素是调整两种聚合物的含量。故选D。

30.细节理解题。根据文章最后——段“Usingthesamestrategybutbyaddinghydrogen,wecoulddisconnectthe

polymersbackintotheirbuildingblocksandeasilyseparatethemtouseagain.Whenwemadenewpolymersout

oftheserecycledplastics,theyperformedjustaswellastheoriginalmaterialsevenafterseveralroundsof

地将它们分离出来再次使用。当我们用这些回收塑料制成新的聚合物时，即使经过几轮化学回收，它们的

性能也和原始材料一样好。）”可知，多嵌段聚合物可以通过添加氢的方式被分离出来再次使用。故选B。

31.主旨大意题。根据文章第一段"Peoplehavecometounderstandtheenormousimpacts-beneficialaswellas

harmful-plasticshaveonhumanlivesandtheenvironment.Aspolymer（聚合物）scientistscommittedto

inventingsustainablesolutionsforreal-worldproblems,wesetouttotackletheissueofplasticwasteby

问题发明可持续的解决方案，我们开始通过重新思考聚合物的设计方式来解决塑料垃圾问题，这样我们就

可以制造出具有可回收性的塑料。）”以及全文内容可知，文章主要讲述了聚合物科学家如何通过重新设计

聚合物的结构来解决塑料废物问题，以实现其可回收性。文章强调了设计的重要性，并介绍了如何通过特

殊的化学方法制造和回收一种新型的多嵌段聚合物。因此，最能概括文章主题的标题应该是强调“设计”和

“回收”这两个关键词的。故选A。
