【文章大意】这是一篇说明文。芝加哥大学的研究人员已经培训出了一个人工智能(AI)系统，

在Yelp上编写虚假评论，足以乱真。其目的是强调这些系统可以很容易地写出像人类写的一

样的评论，如果它们没有被恰当地运用，它们会变得具有破坏性，而这一威胁远远不止如

此。

24.Whatcanthenowartificialintelligencesystemdoaccordingtothepassage?

A.Itcanhelptrainnewreviewers.

B.Itcantelltherealreviewsfromthefakeones.

C.Itcanwritehuman-1ikereviews.

D.Itcaneasilydamagethebusinesses.

【解析】选Co细节理解题。根据文章第一段ResearchersattheUniversityofChicagohave

trainedanartificialintelligencesystem,towritefakereviewsonYelp,awebsite

showingcustomerreviewsonshoppingorsomethingelse,andit'sprettyhardto

tellthemapartfromahumanreview.芝加哥大学的研究人员培训出了一个人工智能系统，

让它在Yelp网站上撰写虚假评论。很难把它们与人类的评论区分开。可知，这种新的人工智

能系统可以撰写出像人类写的一样的评论。故选C项。

25.Whatdoestheunderlinedword“rival“meaninthepassage?

A.Apersonwhorespectsyoudeeply.

B.Apersonwhocompeteswithyou.

C.Apersonwholovestogivefakereviews.

D.Apersonwhocancontrolyoufromdistance.

【解析】选B。词义猜测题。根据文章第三段Sincemanysmallbusinessesrelyononline

crazilyfilltheirpagewithnegativereviewswrittenbyamachineisprettyworrying.

由于许多小企业依赖在线评论来帮助成长和保持声誉，未来有人可能会疯狂地用机器写的负

面评论填满他们的页面，这是相当令人担忧的。可知画线单词所在部分likearivalorangry

customer是someone的同位语，对其进行解释说明。根据上下文语境以及生活常识可以判断

出，对于企业来说，面对的有顾客和竞争对手两类人。因此rival为竞争对手。故选B项。

26.WhatcanweinferfromBenY.Zhao*sremarks?

A.Artificialintelligencecanputthesocietyindanger.

B.Theartificialintelligenceisonlyusedbytheresearchers

C.BenY.Zhaoisoptimisticaboutthefurtherdevelopmentofartificialintelligence.

BenY.Zhao,oneoftheauthorsofthestudy,said."Ithinkthethreattowards

societyislargeanditreallymisleadsusersandshakesourbeliefinwhatisreal

andwhatisnot.Ithinkthat*sgoingtobeevenunimaginable.”“总的来说，威

胁更大，”赵本源说，该研究的作者之一说，“我认为对社会的威胁是巨大的，它真的误导

了用户，动摇了我们对什么是真的，什么不是真的的信念。我认为这甚至是不可想象的。”

可知他认为AI智能会误导用户明辨是非的能力，会对社会带来不可想象的威肋故选A项。

27.Whatisthebesttitleforthepassage?

A.SuggestionsonGivingReviews

B.HowtoTelltheFakeReviews

C.DevelopmentofAIinReviewonYelp

D.AIisComingtoStealYourReviews

【解析】选D。主旨大意题。通读全文可知，芝加哥大学的研究人员已经培训出了一个人工智

能(AI)系统，在Yelp上编写虚假评论，足以乱真。其目的是强调这些系统可以很容易地写

出像人类写的一样的评论，如果它们没有被恰当地运用，它们会变得具有破坏性，而这一威

胁远远不止如此。选项D.AIisComingtoStealYourReviews.体现了这一中心思想。故

选D项。

【文章大意】本文是一篇环境类的短文阅读。文章主要介绍了科学家是如何在亚马孙热带雨

林开展工作的，以揭开亚马孙热带雨林的神秘之处。

32.Howdoscientistsstudythepastclimatechange?

A.Bypredictingtheclimatechangeinthefuture.

B.Bydri1lingdowndeepintolandsediment.

存在湖泥里的花粉化石。故选及

33.Whatisneededfordrillingdownintolakesediment?

A.Thelatesthelicopter.

B.Thespecialequipment.

C.Thelightmachinery.

D.Thenarrowpath.

【解析】选B。细节理解题。根据文中的第三段Goingbacktothelasticeagemeansdrilling

回到上一个冰河时代意味着下钻到湖泊里的沉淀物，这需要专门的设备和重型机械。C选项

D.Towarnpeopletostayawayfromthedangerofrainforests.

【解析】选C。推埋判断题。这是一篇科普文章，通常写作目的是提供佶息。A选项是吸引更

多人对二氧化碳的注意，和文章无关；B选项是号召人们保护雨林，此文不是强调保护雨林;

D选项是警告人们远离雨林的危险，文章没有讲到雨林的危险。故选C。

35.Thebesttitleforthetextmaybe______.

A.MysteryoftheRainforest

B.ClimatesoftheAmazon

C.TheHistoryoftheRainforest

D.ChangesoftheRainforest

人们对于雨林怎样应对气候变化一直没有满意的答案，二、三段讲述的是科学家采用不同的

方法去检测，但没有结果，所以标题为热带雨林之谜是最恰当的。B、C、D选项都仅仅是文

章提到的部分信息。故选A。
