共享题干题 (三) The Robot Man请根据短文的内容，回答问题。 According to Hans Moravec, universal robots will take over all the physical activities that we engage in, leaving us with little housework to do. Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings. In new situations they'll be able to adapt, unlike today's mobile industrial robots. These robots will have the computing power, to cope with simple speech and text recognition, and will be used for tasks such as domestic cleaning. The second generation will arrive around 2020 and will be distinguished by the ability to learn.Second generation robots are programed with sets of primitive tasks and with feedback that provide"pleasure" and "pain" stimuli. For example, a collision provokes a negative response, a completed task would be positive. Move forward another ten years to 2030 and you get to generation three. This robot can build internal simulations of the word around it. Before beginning a task, it can imagine what will happen in order to predict problems. If it has a free moment, it can replay past experiences and try variations in order to fred a better way of doing things next time. It could even observe a person or another robot performing a task and learn by imitation. For the fast time, we have here a robot that can think. By the time we get to generation four in 2040, Moravec predicts that robots will be able. to match human reasoning and behaviour, generalise abstract ideas from specific experience, and conversely,compile detailed plans of action from general commands such as "earn a living" or "make more robots". ( 宣告 ) runs something like this. As robots start to become useful inThe Moravec manifesto generation one, they'll begin to take on many tasks in industry. Driven by the availability of this cheap and tireless labour force, the economy will boom and the demand for robots will grow so rapidly that they will soon become low-cost commodity items, that they'll move into the home,where the domestic robot will relieve us of lots of housework. With increasing automation in generations two and three, the length of the average working day will plummet, eventually to near zero. Most people will be unemployed as robots take over not just primary industry, but the service economy too. Moravec sees the fourth generation as an opportunity to surpass (超越) our human limitations. These future machines will be our "mind children". Like biological children of previous generations, they will embody humanity's best hope for a long-term future.1.[不定向选择题]What will be the distinctive feature of the second generation robots?A.They will be able to learn by themselves. B.They will be able to recognize speeches and texts. C.They will be able to predict problems. D.They will be able to match human reasoning and behavior. 2.[不定向选择题]What does Moravec think of these future robots?A.They will be humans' mind-children. B.They will look like previous biological children. C.They will create a dangerous world. D.They will rule the world.

1.参考答案：A
参考解析：细节题。题干：第二代机器人的主要特征是什么?由关键词second generation定位到第二段第一句“The second generation will arrive around 2020 and will be distinguished by the ability to learn．”，意为“第二代机器人大概在2020年出现，并因为其学习的能力而区别于第一代机器人。”因此A(他们能自己学习)为正确选项。
2.参考答案：A
参考解析：细节题。题干：Moravec怎么看未来的机器人?整篇文章都在介绍Moravec的观点，最后一段第一句“这些未来的机器会成为我们思想上的孩子”。因此选A。3.[不定向选择题]The word "plummet" in Paragraph 6 means __________.A.expand B.decrease C.extend D.grow

这个问题我还想问问老师呢
