店仅需75.75英镑。在Farringdon,一间双人房只需62.95英镑。)，可知本处在讲酒店房间价钱，离火车站越

【答案】24.B25.D26.B27.C

【解析】

本文是说明文。研究表明养狗可以使人类长寿，文章从几方面列举了养狗的好处和对健康的促进作用。

【24题详解】

推理判断题。根据第一段“he(orshe)canalsohelpyoulivelonger,accordingtonewresearch."和第二段"Overall,

ownersofdogs(especiallyhuntingbreeds)havealowerriskofdeathfromcardiovascular(心血管)diseaseorother

causes,theresearchersfound.”可知研究表明狗可以帮助人类长寿，养狗的人死于心血管疾病的风险较低。再加

上第四段列举的养狗能促进长寿的原因，可推知拥有一只狗能使人长寿。故选B。

[25题详解】

词义猜测题。第四段开头“Accordingtotheresearchers,thebenefitscangobothways”点明了养狗的好处是双向

的，下文就列举了其好处。画线词语所在句子的前半句"afamilydogcouldchangetheowner'sbacterial

microbiome(细菌微生物群)byexposingthemtoforeignbacteria,”说明狗可以通过让主人接触外来细菌来改变他

们的细菌微生物群，结合词后的“theirimmunesystemsagainstdisease.”可知是加强免疫系统来对抗疾病，boost

应该是“加强，促进，提高“，与strengthen同义，故选D。

【26题详解】

细节理解题。根据第四段“afamilydogcouldchangetheowner'sbacterialmicrobiome（细菌微生物群）byexposing

themtoforeignbacteria,whichbooststheirimmunesystemsagainstdisease.”可知狗可以通过让主人接触外来细

菌来改变他们的细菌微生物群，加强免疫系统来对抗疾病，A项正确；根据第四段“Owningadogmightalso

increasepeoples*socialinteractionandoverallwell-being,leadingtoalongerlife.”可知养狗还可以增加人们的社

会交往和整体幸福感，从而延长寿命，C项正确；根据第二段“ownersofdogs（especiallyhuntingbreeds）havea

lowerriskofdeathfromcardiovascular（心血管）diseaseorothercauses,“可知养狗的人死丁心血管疾病的风险较

低，D项正确；根据第一段“he（orshe）canalsohelpyoulivelonger,accordingtonewresearch.”及全文内容可知

养狗可以使人类长寿，但文中并没有说能延长狗的寿命，B项表达错误，故选B。

[27题详解】

细节理解题。根据文章最后Dr.MikeKnapton说的“However,asmanydogownersmayagree,themainreasonfor

owningadogisthesheerjoy."（然而，许多养狗的人可能会同意，养狗的主要原因是纯粹的乐趣。）可知Dr.Mike

Knapton认为许多美国家庭养狗是因为狗能给他们带来更多乐趣，故选Co

thisproblemfordecades.Theysaythatlightpollutionpreventsthemfromseeingobjectsintheskythattheycould

seequiteeasilyinthepast.（天文学家——研究恒星和行星的科学家——已经抱怨这个问题几十年了。他们说，

光污染使他们看不到过去很容易看到的天空物体）''可知，天文学家们抱怨光污染问题多年来一直没有得到解

决。故选A。

【30题详解】

细节理解题。根据最后一段中“Foryears,Flagstaff,Arizona,hasenforcedlightingregulationsinitscityinorderto

良影响。可推知，作者最想传达给我们的信息是：人类活动应该是环保的。故选D。

谈能与我们与其他人建立持久的联系，形成宝贵的友谊，使我们的生活充满活力，友谊从闲聊开始，着重描

述了闲聊的意义。

[32题详解】

主旨大意题。根据第一段"Butdespitebeingevidentandoftenpainfullydull,smalltalkhasanimportantroleto

fulfil,enablingustoleapoveranumberofsocialobstaclestowardsimproved,meaningfulinteraction/不过，尽管闲

聊往往明显枯燥得令人痛苦，但它仍能发挥重要作用，使我们能够跨越许多社会障碍，改善有意义的互动。）”

可知，闲聊是跨越许多社会障碍，改善互动的方式，由此可知，第一段讲述的是：闲聊是人类互动的第一步，

故选A项.

【33题详解】

推理判断题。根据第二段“Whenfindingyourselfpositionedcloselytoapersonwhoyouknowlittleabout,it's

muchsafertopointouttherainyskythantoshareyourpoliticalviewsonasensitivetopic.Untilyouknowthe

acoldstare.（当你发现自己靠近一个你不太了解的人时，聊天气情况要比就一个敏感话题发表你的政治观点安

全得多。在你更好地了解对方之前，较严肃的话题应该保密，这样你才不会被冷眼瞪着。）”可知，如果闲聊

故选D项。

【34题详解】

细节理解题。根据第三段“Aresponseto"howwasyourweekend"canunveilmuchabouttheperson（scharacter.

Thelengthoftheirresponsemightindicatetheirlevelofself-confidence;thetoneofspeakingmightshowhow

agreeableapersonis;（对“周末过得怎么样”的回答可以揭示出这个人的很多性格特征。他们回答的长度可能表

明了他们的自信程度;说话的语气可以显示出一个人是多么和蔼可亲;）”可知体现一个人友好、和蔼的标志是说

话的语气。故选B项。

【35题详解】

标题判断题。根据第一段“Butdespitebeingevidentandoftenpainfullydull,smalltalkhasanimportantroleto

fulfil,enablingustoleapoveranumberofsocialobstaclestowardsimproved,meaningfulinteraction4不过，尽管闲

聊往往明显枯燥得令人痛苦，但它仍能发挥重要作用，使我们能够跨越许多社会障碍，改善有意义的互动。）”

和结合最后一段"Conversationisagreateducator,anddeepconversationestablishlastingbondswith

ourfellowhumans,formingpreciousfriendshipsthatpaintourliveswithvibrantcolors.Suchfriendshipsbeginwith

smalltalk.（交谈是伟大的教育家，深入的交谈能与我们的同胞建立持久的联系，形成宝贵的友谊，使我们的生
