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,softwarefirsthastorecognisetheshapeofahumanbodyandthenmapoutthekeypointsofourbody.”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“Butunderstandingthatanimageesprettyeasily.”以及第四段“Butcomputersneedtoseeaton...sameorsimilarstancewiththatemotion.”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...sameorsimilarstancewiththatemotion.”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...whatyourbodylanguageissaying.”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。故选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SilboGomero。5.B细节理解题。根据第三段中的“Itstartedtodieoutwhenthetelephonearrivedandtheislandwasopentotourism.”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“ItsoundslikebirdsongandwasdevelopedthousandsofyearsagobyislanderstoenablethemtocommunicateuptotwomilesacrossLaGomera’svalleys.”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“TheCanaryIslandsgovernmentisprovidingfundingtohelpschoolchildrenonLaGomeratolearnthisancientwhistlinglanguageaspartoftheirheritage.”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“SilboGomeroisanancientlanguageofwhistlethatenabledpeopletocommunicateacrosslongdistancesbeforetheinventionofthetelephoneorthecomputer.”以及文章内容可知,本文写作的目的是介绍LaGomera岛上濒临消亡的口哨语SilboGomero。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—andthatwilllikelyremainfortheforeseeablefuture.”说明人们戴口罩时脸会被隐藏一半。下文“Howcanwebetterreadbodylanguage,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,whenweshouldalsobeobservingthemovementsoftheirentireupperbodies.”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’(thevisibleindentationatthemiddle-frontoftheirneck),itcouldmeanthey’redistressedorinsecure.”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”是对此提出的建议,符合语境。故选B项。4.A根据下文“Ifsomeoneisrubbingtheupperpartoftheirchestwithapalmofahand(orevenjustthefingers),itcanindicatediscomfortorconcern.”可知,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...displaysawarenessandattentiveness
