参考答案

UNIT4

单元提能强化练

i.【语篇导读】本文是一篇说明文。文章主要说明了计算机理解人类肢体语言的详细步

骤。

1.C细节理解题。根据第二段中的“So,softwarefirsthastorecognisetheshapeofahuman

bodyandthenmapoutthekeypointsofourbody.”可知，要让计算机理解人类的肢体语■言,

最重要的是软件。故选C项。

2.D推理判断题。根据第三段“Butunderstandingthatanimageespretty

easily."以及第四子殳“Butcomputersneedtoseeaton...sameorsimilarstancewiththat

emotion”可知，因为肘部、膝盖或一张脸的图像对计算机理解人类肢体语言并没有多大好

处,所以计算机关注可以传达情绪的脸(面部表情)和手(肢体语言)。因此，把情绪被分为肢

体语言和面部表情是为了让计算机识别它们背后的意义。故选D项。

3.B词义猜测题。根据画线词所在的上下文“Butcomputers...sameorsimilarstancewith

thatemolion.”可知，计算机识别的是特定肢体语言背后的意义;通过越来越多肢体语言的

例子，计算机可以识别出那种肢体语言情绪状况下相同或相似的意思。故画线词意思是

“意义故选B项。

4.A主旨大意题。根据第一段“Gettingcomputerstounderstand...whatyourbodylanguage

issaying.”并结合全文内容可知，本文主要说明了计算机理解人类肢体语言的详细步骤。A

项”计算机是如何识别肢体语言的”最符合本文大意。改选A项。

【语篇导读】本文是一篇说明文。文章主要介绍了LaGomera岛上的口哨语Silbo

GomeiOo

5.B细节理解题。根据第三段中的"Itstartedtodieoutwhenthetelephonearrivedandthe

islandwasopentotourism.“可知，现代技术的到来是SilboGomero濒临消亡的原因。故选

B项。

6.C细节理解题。根据第二段中的“Itsoundslikebirdsongandwasdevelopedthousandsof

yearsagobyislanderstoenablethemtocommunicateuptotwomilesacrossLaGomeraJs

valleys.”可知,SilboGomero被发明出来是为了进行远距离交流。故选C项。

7.A细节理解题。根据第二段中的“TheCanaryIslandsgovernmentisprovidingfundingto

helpschoolchildrenonLaGomeratolearnthisancientwhistlinglanguageaspartoftheir

heritage”可知，为了拯救SilboGomero,当地政府提供了财政援助。故选A项。

8.D推理判断题。根据第一段中的“SilboGomeroisanancientlanguageofwhistlethat

enabledpeopletocommunicateacrosslongdistancesbeforetheinventionofthetelephoneor

thecomputer.^^以及文章内容可知，本文写作的目的是介绍LaGomera岛上濒临后亡的口

哨语SilboGomeroo故选D项。

II.【语篇导读】本文是一篇说明文。在疫情期间，社交距离极大地改变了我们在非语言

交流方面的方式。对此文章给出了快速阅读肢体语言的建议。

1.G上文“Wearingafacemaskhasquicklybecomethenorm-andthatwilllikelyremain

fortheforeseeablefuture.”说明人们金口罩时脸会被隐藏一半。下文“Howcanwebetter

readbodylanguage,nowthatwe'rewearingmasks?”说明,在脸被隐藏的情况下，我们仍旧

要辨别人们所想。G项“但是，由于隐藏了近一半的脸,因此很难分辨出一个人的想法和感

受”承上启下，符合语境。故选G项。

2.E根据上文“Toooften,weputallourfocusonpeople*sfaces,whenweshouldalsobe

observingthemovementsoftheirentireupperbodies.”可知，在观察不到脸的同时，我们应注

意观察人们的肢体语言,通过肢体语言来解读人们的心理。E项“肢体语言是一个人情绪

状况的外在反映”承接上文。故选E项。

3.B根据上文“Ifpeoplearetouchingtheir'neckdimple'(thevisibleindentationatthe

middle-frontoftheirneck),itcouldmeanthey'rcdistressedorinsecure.''可知，一个人在感

到焦虑或不安时会摸脖子的凹陷处。B项中的“this”指代触摸这个部位，而“尝试安慰他们

或缓解他们的焦虑''是对比提出的建议，符合语境。故选B项。

4.A才艮据下文“Ifsomeoneisrubbingtheupperpartoftheirchestwithapalmofahand(or

evenjustthefingers),itcanindicatediscomfortorconcern.,,15T知，本段落承接上段内容，介绍

的是压力和焦虑的另一个迹象以及相应的建议。故选A项。

5.F根据上文“Headmovementscan...displaysawarenessandauemiveness.”可知,上文说

的是人们在专注时的头部动作。F项“当与一些点头结合时,它可以表示对所说或听到的

内容的赞同'‘符合语境。故选F项。

III.【语篇导读】本文是一篇记叙文。作者某次去看牙医，去之前已经预约了，到了那里却

发现牙医什么都没准备。作者很生气,但牙医却一直对作者微笑，这让作者很内疚,也让作

者感受到了微笑的力量。

l.Bfriend朋友;stranger陌生人;patient病人;relative亲或。根据下文所提到的故事可

知，此处指微笑能为破陋生人之间的隔阂O

2.Dinterview采访;operation手术;experiment实脸;appointment约定,约会。作者要去

看病，所以应该是同医生提前有预约。

3.Cconclude得出结论;approve赞同，支持;ensure确保;apply申请,应用。根据空前提到

的“confirmedittwice''可
