【文章內容簡介】 i尚未進入市場，還談不上公眾對 Shimi欣賞與否的問題，因此選項 C不符合原意； Shimi正在進行商業(yè)化運作，但絕非已經完成，所以 D也不是正確選項。本題的答案是 B,依據是最后一段倒數第二句。 參考譯文 第十九篇 音樂機器人伴侶提升音樂欣賞體驗 Shimi是由佐治亞理工大學音樂技術中心研發(fā)的一款音樂伴侶。它可以根據聽者的反饋推薦合乎節(jié)拍的歌曲、舞蹈；并且不 斷播放音樂。這款髙 1英尺的機器人是由智能手機系統(tǒng)支持的，因此被標榜為 “一個可以互動的音樂朋友 ”。 Gil Weinberg教授是該機器人的發(fā)明者，他解釋說： “Shimi設計的宗旨是改變人們欣賞音樂、認識音樂的方式。 ”他將在今年 6月 27日在舊金山的谷歌 I/O大會上展示這款機器人。一個由三個機器人組成的樂隊將為來賓演奏，并伴隨音樂起舞。而音樂是根據不同的運動形式編制的。 Shimi實際上是一個擴充基座，它的 “大腦 ”由安卓手機控制。一旦連接上，機器人便從用戶的移動裝置獲得傳感和音樂生成能力。換言之，只要有應用程序 ，機器人便能使用。例如，通過手機的照相機和辨認臉型的軟件， Shimi就能在房間周圍跟蹤到聽眾，然后安置好它的 “耳朵 ”或揚聲器，以確保輸送最佳聲音。另外一種識別特征是基于節(jié)奏和速度。如果用戶打出某個（音樂）拍子， Shimi會對此進行分析，然后瀏覽手機的音樂庫，并立即演奏最符合要求的音樂。一旦音樂響起來， Shimi就隨韻律起舞。 “許多人認為機器人受到程序指令的限制，而 Shiini給我們展示了機器人可以具有創(chuàng)造力和與人交互的能力。 ”音樂技術博士研究生 Mason Bretan如是說。正在研發(fā)中的程序將使用戶能溝通 過搖頭或擺手表示不同意，來提醒 Shimi跳到下一首歌或增減音量。機器人還可根據用戶對歌曲的選擇推薦新音樂，并對音樂播放列表提供反饋。 Weinberg希望其他研發(fā)者會因此獲得靈感，開發(fā)更多的應用程序，來擴展 Shimi的創(chuàng)新和交互功能。他說： “我認為我們中心正在引領這場將更多機器人應用到家庭中去的變革。 ” Weinberg正在通過獲得佐治亞理工學院的獨家授權來對 Shimi進行商業(yè)推廣。Weinberg希望到 2020年的節(jié)日季消費者可購買到 Shimi。 Weinberg說： “如果機器人進入家庭，我們認為就應該是這 種類型的機器人：小巧、令人愉快和有趣，它們能提高我們的生活質量，為更多智能服務型機器人進人我們的生活做好準備。 第四十八篇 Researchers Discover Why Humans Began Walking Upright Most of us walk and carry items in our hands every day. These are seemingly simple activities that the majority of us don?t question. But an international team of researchers, including Dr. Richmond from GW39。s Columbian College of Arts and Sciences， have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce, high quality resources. The team of researchers from the U. S., England, Japan and Portugal investigated the behavior of modernday chimpanzees as they peted for food resources， in an effort to understand what ecological settings would lead a large ape — one that resembles the 6 millionyear old ancestor we shared in mon with living chimpanzees — to walk on two legs. “These chimpanzees provide a model of the ecological conditions under which our earliest ancestors 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 in situations where they need to monopolize a resource. Standing on two legs allows them to carry much more at one time because it frees up their hands. Over time， intense bursts of bipedal activity may have led to anatomical changes that in turn became the subject of natural selection where petition for food or other resources was strong. Two studies were conducted by the team in Guinea. The first study was conducted by the team in Kyoto University?s “ outdoor laboratory ” in a natural clearing in Bossou Forest. Researchers allowed the wild chimpanzees access to different binations of two different types of nut — the oil palm nut， which is naturally widely available, and the coula nut, which is not. The chimpanzees? behavior was monitored in three situations:(a) when only oil palm nuts were available,(b)when a small number of coula nuts were available， and(c) when coula nuts were the majority available resource. When the rare coula nuts were available only in small numbers, the chimpanzees transported more at one time. Similarly, when coula nuts were the majority resource, the chimpanzees ignored the oil palm nuts altogether. The chi mpanzees regarded the coula nuts as a more highlyprized resource and peted for them more intensely. In such highpetition settings， the frequency of cases in which the chimpanzees started moving on two legs increased by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource, but also that they were actively trying to move as much as they could in one go by using everything available 一 even their mouths. The second study, by Kimberley Hockings of Oxford Brookes University, was a 14month study of Bossou chimpanzees cropraiding, a situation in which they have to pete for rare and unpredictable Resources. Here, 35 percent of the chimpanzees activity involved some sort of bipedal movement, and once again, this behavior appeared to be linked to a clear attempt to carry as much as possible at one time. 詞匯 ： scarce ， 不足的 ； 稀 有的 chimpanzee ape 。 類人猿 bipedal adj. 二足的 anatomical coula nuts( coula也可寫作 cola或 kola)可樂果 注釋 ： 1.
