10、sibility ofmaking a machine with human-like abilityC. once we make a machine as complex as the human brain, it will posses intelligenceD. robots will have control of the vast, man-made world in space1.C 事实细节题。第1段末提到，使机器具有智能的方法有两种，要么安装合适软件，要么改变其架构，故C正确。2.A 观点态度题。作者在最后一段提到智能机器人可为人类做很多好事，故他对机器人态度是肯定的，故

11、A正确，同时排除C。文中只是说机器人会超越人类,但并未提到会控制人类，故B排除;D与第1段末的that toowill happen矛盾，故错误。3.D 词义理解题。文中提到硅将会终结碳的长期统治地位，联系上文可知，硅指的是智能机器人，再结合上文的机器人会超越人类，故可确定碳指代的是人类。4.A 事实细节題。第3段首提到，智能机器人能帮助开发边远地区的条件是intelligence. increase tomatch thatof humans和cost declines,A与此相对应,故正确。5. B 推理判断題。综观全文，作者讨论制作智能机器人的可能性及其影响，B所述与此相符。文中指出智能

12、机器人的自我繁殖就是设计自己，故A错误;第1段指出在制作出与人脑一样复杂的机器人后，还必须花很长时间安装软件或改变架构后才能使其拥有智能，故C错误;D中的控制人造世界属过度推断，文中并未提及。The human brain contains 10 thousand million cells and each of these may have a thousandconnections.
