2002 Text 2

　　Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics — the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.

　　As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy — far greater precision than highly skilled physicians can achieve with their hands alone.

　　But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves — goals that pose a real challenge. "While we know how to tell a robot to handle a specific error," says Dave Lavery, manager of a robotics program at NASA, "we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world."

　　Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.

　　What they found, in attempting to model thought, is that the human brain's roughly one hundred billion nerve cells are much more talented — and human perception far more complicated — than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on Earth can't approach that kind of ability, and neuroscientists still don't know quite how we do it.

難句解析：

①Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty.
▲該句是一個(gè)復(fù)雜單句，前面是since引導(dǎo)的一個(gè)時(shí)間狀語，這個(gè)地方的dawn取其比喻的意思，表示早期。后面主句中有一個(gè)定語從句that is dangerous, boring, burdensome, or just plain nasty用來修飾work。
△本句結(jié)構(gòu)比較簡明，但是有一些詞的意思比較難：ingenuity創(chuàng)造性，靈活性；nasty討厭的。

②As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor.
▲本句的主句是the modern world is increasingly populated by intelligent gizmos，后面是兩個(gè)定語從句，中間用but來引導(dǎo)。
△要看懂本句，重點(diǎn)在于看到gizmo一詞后面的兩個(gè)定語從句。在本句中，認(rèn)不認(rèn)識(shí)gizmo并不重要，因?yàn)閺纳舷挛闹锌梢钥闯鏊?/span>robot的意思應(yīng)該大同小異。

③There are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy — far greater precision than highly skilled physicians can achieve with their hands alone.
▲該句是一個(gè)there be的結(jié)構(gòu)，注意robot systems后面有一個(gè)修飾它的定語從句。而后面的破折號(hào)引出一個(gè)補(bǔ)充說明部分來修飾submillimeter accuracy。
△注意該句中的最核心的部分是robot systems，其它成分都是圍繞著它來展開的。

④But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves — goals that pose a real challenge.
▲整句是一個(gè)條件句，注意后面的主句比較復(fù)雜，里面有兩個(gè)并列的謂語，而后面破折號(hào)引導(dǎo)的是一個(gè)補(bǔ)充說明成分，修飾整個(gè)主句。
△要注意兩個(gè)并列謂語之間的關(guān)系。

⑤But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd.
▲整句的主干部分是這樣的，主語the human mind，并列謂語glimpse和disregard，逗號(hào)后面instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd這一部分做狀語，修飾謂語。
△要注意兩個(gè)并列謂語之間的關(guān)系并抓住句子的主干成分。

試題解析：

46. [C]
　　此題的難度合適，區(qū)分度好。
　　本題是一個(gè)局部題，主要考查考生是否看懂了第一段，尤其是“That compulsion has resulted in robotics — the science of conferring various human capabilities on machines”這句話。這句話的意思是：（發(fā)明一些靈巧的工具來從事一些危險(xiǎn)、乏味、繁重，或者是討厭的工作）這樣一種需求導(dǎo)致了機(jī)器人技術(shù)的產(chǎn)生，即賦予機(jī)器以人的各種技能的科學(xué)。

47. [C]
　　此題偏易，區(qū)分度很好。
　　本題是考查考生從上下文猜測(cè)詞義的能力。根據(jù)第二段中出現(xiàn)的“robot assembly arms”，“automated teller terminals”，“tireless robo-drivers”等信息，考生可以猜出“gizmos”是“設(shè)備、裝置”的意思。

48. [D]
　　此題的難度合適，區(qū)分度很好。
　　本題的答題依據(jù)是第三段中Dave Lavery的第二句話，即“we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world.”該句中的“dynamic”就是“動(dòng)態(tài)的、變化的”意思。

49. [B]
　　此題的難度合適，區(qū)分度好。
　　本題的答題依據(jù)是第三段中Dave Lavery說的第一句話，即“While we know how to tell a robot to handle a specific error,”即我們知道如何告訴機(jī)器人去處理一個(gè)具體的錯(cuò)誤。看懂了這句話，這道題就很容易了。

50. [C]
　　此題屬于很容易的題目，區(qū)分度好。
　　本題考的是文章最后一段的意思。該段的主要意思是：機(jī)器人能夠在很短的時(shí)間內(nèi)發(fā)現(xiàn)機(jī)器的問題，而人腦能很快忽略不相關(guān)的信息，而將注意力集中到相關(guān)的信息上來，這是先進(jìn)的機(jī)器人都做不到的。

全文翻譯：

　　從人類最初有了智慧至今，人們一直在設(shè)計(jì)日益巧妙的工具來處理那些危險(xiǎn)的、枯燥的、繁重的或者只是一般骯臟的工作。這種不得已的行為導(dǎo)致了機(jī)器人科學(xué)的產(chǎn)生——一門將人類的能力賦予機(jī)器的科學(xué)。如果科學(xué)家們還沒有在機(jī)械上實(shí)現(xiàn)科幻小說的幻想，那么他們也已經(jīng)很接近這個(gè)目標(biāo)了。
　　由此引起的結(jié)果是，現(xiàn)代世界已經(jīng)日益充斥著智能的裝置，雖然我們幾乎都注意不到他們，但他們的普遍存在卻節(jié)省了許多人類勞力。我們的工廠里轟鳴著機(jī)器人生產(chǎn)線的節(jié)奏；我們的金融服務(wù)完成于自動(dòng)柜員機(jī)旁，完成業(yè)務(wù)后，它們還會(huì)機(jī)械地、有禮貌地感謝我們；我們的地鐵車輛由不知疲倦的機(jī)器人駕駛。由于電子和微觀機(jī)械儀器的不斷縮小，現(xiàn)在已有一些機(jī)器人系統(tǒng)能夠進(jìn)行精確到毫米的腦部和骨髓手術(shù)，其精確性遠(yuǎn)遠(yuǎn)超過熟練的醫(yī)生用他們的雙手所能達(dá)到的水平。
　　但是如果機(jī)器人要進(jìn)入節(jié)省勞力的下一個(gè)階段，他們必須能夠在更少的人工監(jiān)控下運(yùn)行，并且至少能夠獨(dú)立地做一些決定。這些目標(biāo)給我們提出了一個(gè)真正的挑戰(zhàn)?！半m然我們知道如何讓機(jī)器人去糾正一個(gè)特定的錯(cuò)誤，”NASA的一個(gè)機(jī)器人項(xiàng)目經(jīng)理戴維·拉維里說，“我們?nèi)匀徊荒苜x予機(jī)器人以足夠的‘常識(shí)’，使它們能夠與動(dòng)態(tài)的世界進(jìn)行可靠的交流?！?/span>
　　實(shí)際上對(duì)真正的人工智能的追求已經(jīng)產(chǎn)生了各種各樣的效果。雖然一開始在20世紀(jì)60年代和70年代有過一段樂觀的時(shí)期——那時(shí)候仿佛晶體管電路和微處理器的發(fā)展將使他們?cè)?/span>2010年能夠模仿人類大腦的活動(dòng)——但是最近研究人員已經(jīng)開始將這個(gè)預(yù)測(cè)延后數(shù)十年，甚至數(shù)百年。
　　在試圖建造思維模型的過程中，研究人員發(fā)現(xiàn)，人類大腦中的近1000億個(gè)神經(jīng)細(xì)胞要比以前想像的更聰明，人類的感覺器官也比以前想像的更復(fù)雜。他們建造的機(jī)器人在嚴(yán)格控制的工廠環(huán)境里，能夠在儀表盤上識(shí)別毫米以下的誤差。但是人的大腦能夠掃描一個(gè)快速變化的場(chǎng)景，迅速排除98％的不相干的物體，立即聚焦于森林中婉蜒道路旁的一只猴子，或者人群中的一張可疑的臉。地球上最先進(jìn)的計(jì)算機(jī)系統(tǒng)也不能仿效這種能力，并且神經(jīng)學(xué)科學(xué)家仍然不知道我們是怎樣做到這一點(diǎn)的。
