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.
47. The word “gizmos" (line 1, paragraph 2) most probably means .
[A] programs
[B] experts
[C] devices
[D] creatures
[答案] C
[解题思路]
该词语所在的句子为“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”(现代世界日益充斥着各种智能装置，虽然我们几乎都注意不到它们，但它们的普遍存在已使人们摆脱了很多劳动)，从句子总体来判断，尤其是gizmos后面的这个定语从句来判断，这里指的应该是devices。文章后面也提到了很多devices，如robot assembly arms, automated teller terminals, robo-drivers等等，这些都有助于判断并作出正确的选择。
