Shimi 是一种电子设备;B 与原文不符 Shimi 不是该机器人的发明者 Gil Weinberg 教授才是 the robot’s creator.2. D 选项 D 简要地表述了第三段的倒数第二句“If the user taps a beat Shimi analyzes it scansthe phone’S musical library and immediately plays the song that best matches the suggestion”的意思 所以是答案. 选项 A、B. C 都不符合上述句子的含义.3. D 选项 A 的意恩与原文相反. 虽然人们认为机器人受到程序指令的限制 值 Shimi 却表现出具有创造能力和互动能力 所以 A 不是答案. 选项 D 的意思与原文相同 因而是答案. 第四段第三句指的是未来的应用程序:future apps in the works 而选项 B C 是指目前的应用程序 两者的表述均与原文有蹬入.4. A 第三段介绍 Shimi 的多种功能 第四段和第五段说 Weinberg 还在开发更多的应用程序来丰富 Shimi 的功能 还希望其他研发者也参与开发 因此 A 是答案. 选项 B 说 Weinberg仅仅希望 Georgia Tech 员工参与开发恩多的应用软件 这与原文不符. 文章最后~段告诉我们 Weinberg 正在与 Georgia Tech 进行有关 Shimi 商业化的谈判 选项 C 的意思与此相反 不会是答案. 选项 D 也与原文不符.5.B 选项 A、C 和 D 的内容 Weinberg 都没有说过. 第三段告诉我们 Shimi 是 Androidsmartphone 的扩充基座 并不适用于所有智能手机 所以 A 选项不正确;Shimi 尚未进入市场 还谈不上公众对 Shimi 欣赏与否的问题 因此选项 C 不符合原意;Shimi 正在进行商业化运作 但绝非已经完成 所以 D 也不是正确选项. 本题的答案是 B 依据是最后一段倒数第二句. 第四十八篇 Researchers Discover Why Humans Began Walking UprightMost of us walk and carry items in our hands every day. These are seemingly simple activities tllatthe majority of us don’t question. But an international team of researchers including Dr.Richmond from GW’s Columbian College of Arts and Sciences have discovered that humanwalking upright may have originated millions of years ago as art adaptation to carrying scarcehigh-quality resources.The team of researchers from the U. S. England Japan and Portugalinvestigated the behavior of modem. day chimpanzees as they competed for food resources in aneffort to understand what ecological settings would lead a large ape~one that resembles the 6million-year old ancestor we shared in common with living chimpanzees-to walk on two legs.“These chimpanzees provide a model of the ecological conditions under which our earliestancestors might have begun walking on two legs ”said Dr. Richmond.The research findings suggest that chimpanzees switch to moving on two limbs instead of four insituations where they need to monopolize a resource. Standing on two legs allows them to calTymuch more at one time because it flees up their hands.Over time intense bursts of bipedalactivity4 may have led to anatomical changes that in turn became the subject of natural selectionwhere competition for food or other resources was strong.Two studies were conducted by the team in Guinea.The first study was conducted by the team inKyoto University’s “Outdoor laboratory”in a natural clearing in Bossouo Forest. Researchersallowed the wild chimpanzees
access to different combinations of two different types of nut-theoil palm Nut which is naturally widely available and the coula nut which is not thechimpanzees’ behavior was monitored in three situations:awhen only oil palm nuts wereavailable bwhen a small number of coula nuts were available. andcwhen coula nuts were themajority available resource.When the rare coula nuts were available only in small numbers. the chimpanzees transported moreat one time. Similarly when coula nuts were the majority resource the chimpanzees ignored theoil palm nuts altogether.The chimpanzees regarded the coula nuts as a more highly-prizedresource and competed for them more intensely.In such high-competition settings the frequency of cases in which the chimpanzees startedmovingon two legs increased by a factor of four. Not only was it obvious that bipedal movement allowedthem to carry more of this precious resource but also that they were actively trying to move ” asmuch as they could in one go by using everything available—even their mouths.The second study by Kimberley Hockings of Oxford Brookes University was a l4-month studyof Bossou chimpanzees crop-raiding a situation in which they have to compete for rare andunpredictable resources. Here 35 percent of the chimpanzees’activity inv.
