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 robot drivers. And thanks to the continual miniaturization of electronics and micromechanics, 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 La-very , 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 brains 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 cant approach that kind of ability, and neu-roscientists still don’t know quite how we do it.
Human ingenuity was initially demonstrated in______.
选项
A、the use of machines to produce science fiction
B、the wide use of machines in manufacturing industry
C、the invention of tools for difficult and dangerous work
D、the elite s cunning tackling of dangerous and boring work
答案
C
解析
解题的关键在于准确理解第一句话的含义,句中并没有强调the elite精英人才,只提到“people have devised cunning tools”,因此排除选项D精英人才机智地应付危险和枯燥的工作,而A、B两项都不符合题中initially最初、最早这一要求,故选C。
