【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.

选项
答案
由于微电子技术和微型机械学的不断发展,已经出现了能够进行各种脑部和骨科手术的机器人系统,它们的精确程度可以达到亚毫米的程度,这种精确程度是任何一个技艺高超的医生也无法用双手达到的。
解析
这是一个以there be为主干的复合句,含有一个that引导的宾语从句,和一个 than引导的比较状语从句。注意句中破折号后面部分,这实际是对submillim eter accuracy进行进一步说明,作者意在强调。翻译时一定要另译成一个句子,而且要重复这个名词。
