阅读理解A robot with a sense of touch may one day feel "pain"， ‘both its own physical pain and sympathy-for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up（连接） to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial "pain nervous system"， as Asada calls it, may be a small building block for a machine that could experience pain. Such a feeling might also allow a robot to "sympathize" with a human companion's suffering.Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic-looking child's head, these touch and pain signals can be converted to emotional facial expressions.A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin "allows the possibility of engagement in truly intelligent ways".Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care' for people in need, the elderly, for instance. But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that's capable of approximating an internal feeling, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is "along the lines of having a robot, for example, that smiles when you talk to it," Damasio says."While that's an interesting development, it's not the same thing as a robot designed to express somesort of internal experience," he says. （1） What do we know about the "pain nervous system"? A . It is named Affetto by scientists. B . It is a set of complicated sensors. C . It is made up of small building blocks. D . It combines sensors and artificial skin. （2） What does the underlined word "converted" in Paragraph 3 probably mean? A . delivered B . transformed C . connected D . adapted （3） What does Damasio consider as an interesting development? A . Robots can talk to human beings. B . Robots can give unforeseeable responses. C . Robots can detect pain and respond accordingly. D . Robots can express some sort of internal feelings. （4） What can be the best title of the text? A . Human feelings can be felt B . Machines become emotional C . Robots inch closer to feeling pain D . Robots will touch the human heart 答案： D B C C
