问题    In 1981 Kenji Urada, a 37-year-old Japanese factory worker, climbed over a safety fence at a Kawasaki plant to carry out some maintenance work on a robot. In his haste, he failed to switch the robot off properly. Unable to sense him, the robot’s powerful hydraulic arm kept on working and accidentally pushed the engineer into a grinding machine. His death made Urada the first recorded victim to die at the hands of a robot.
   This astounding industrial accident would not have happened in a world in which robot behavior was governed by the Three Laws of Robotics drawn up by Isaac Asimov, a science fiction writer. The laws appeared in 1, Robot, a book of short stories published in 1950 that inspired a Hollywood film. But decades later the laws, designed to prevent robots from harming people either through action or inaction, remain in the realm of fiction.
   With robots now poised to emerge from their industrial cages and to move into homes and workplaces, roboticists are concerned about the safety implications beyond the factory floor. To address these concerns, leading robot experts have come together to try to find ways to prevent robots from harming people. "Security, safety and sex are the big concerns," says Henrik Christensen, chairman of the European Robotics Network at the Swedish Royal Institute of Technology in Stockholm, and one of the organisers of the new roboethics group. Should robots that are strong enough or heavy enough to crush people be allowed into homes? Should robotic sex dolls resembling children be legally allowed?
   These questions may seem esoteric but in the next few years they will become increasingly relevant, says Dr. Christensen. According to the United Nations Economic Commission for Europe’s World Robotics Survey, in 2002 the number of domestic and service robots more than tripled, nearly outstripping their industrial counterparts. Japanese industrial firms are racing to build humanoid robots to act as domestic helpers for the elderly, and South Korea has set a goal that 100% of households should have domestic robots by 2020. In light of all this, it is crucial that we start to think about safety and ethical guidelines now, says Dr. Christensen.
   So what exactly is being done to protect us from these mechanical menaces? "Not enough," says Blay Whitby, an artificial-intelligence expert at the University of Sussex in England. This is hardly surprising given that the field of "safety-critical computing" is barely a decade old, he says. But things are changing, and researchers are increasingly taking an interest in trying to make robots safer. One approach, which sounds simple enough, is to try to program them to avoid contact with people altogether. But this is much harder than it sounds. Getting a robot to navigate across a cluttered room is difficult enough without having to take into account what its various limbs or appendages might bump into along the way.
   Regulating the behavior of robots is going to become more difficult in the future, since they will increasingly have self-learning mechanisms built into them, says Gianmarco Veruggio, a roboticist at the Institute of Intelligent Systems for Automation in Genoa, Italy. As a result, their behavior will become impossible to predict fully, he says, since they will not be behaving in predefined ways but will learn new behavior as they go.
Which of the following statements is NOT true of robots?
选项 A、It’s difficult to prevent robots from contacting people.
B、The behavior of robots will be more unforeseeable.
C、Robots in the future will be more intelligent than those today.
D、Programming robots through a cramped room is the most difficult task
答案D
解析 细节题。末段第二句指出As a result，their behavior will become impossible to predict fully．．．，[B]符合文意。第五段第五、六句提到One approach．．．is to try to program them to avoid contact with people．．． But this is much harder…,[A]符合文意。第五段末句指出：操纵机器人穿过凌乱的房间就是很困难的事了，更不用说考虑它的肢体在路上碰到什么了。可见后者比前者更为困难，[D]与文意不符，故为答案。
