问题      【61】 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.
     【62】 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 robot-drivers. 【63】 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. 【64】 De spite 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, re searchers 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 millimeter in a controlled factory environment. 【65】 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 quite know how we do it.
【65】
选项
答案但是，人类的大脑可以在瞥一眼快速变动的场面之后立即摒弃98%的无关信息，可立即把目光锁定在崎岖森林道路旁的一只猴子，或是人群中的一张可疑的脸。
解析 本句是一个复合句，句子的主干为…the human mind can glimpse…a scene and…disregard…。其中that is irrelevant是一个定语从句修饰the 98 percent。现在分词 focusing on the monkey…or the single suspicious face…作状语表示伴随情况。本句基本可以按顺译法翻译，the 98 percent指人在一瞥之间看到的绝大部分事物，在此可以引申为“获得的信息”。作伴随情况的现在分词短语，要翻译成一个独立的句子，置于主句后面。
