Ⅱ.阅读理解 A We can find robots everywhere. Robots build cars, play chess and can clean your house. They may drive your car in the near future. Two robots, named Spirit and Opportunity, were sent to Mars on a mission (任务) to explore the red planet. Robots also help people in natural disasters. They are used in search and rescue operations following an earthquake or a nuclear accident. In most cases, robots are sent to places considered to be unsafe. The problem is that all of those types of situations are extremely unpredictable and unfriendly. And it is very likely that robots in those situations become damaged. When a dog loses a leg, the animal eventually finds the best way to get around on three legs. In a short time, the dog learns to deal with its physical disability. Now, scientists have developed robots that behave in the same way. Jeff Clune, a computer scientist, is developing the latest and advanced technology so that robots will continue operating after the first sign of injury. He wants the machines to have the ability to analyze the cause and change to continue performing until they can be repaired. The researchers have added one more operation to the skill set of robots working under complicated conditions. They programmed a hexapod robot with six legs and a robotic arm. Their findings were reported in the journal Nature. Once the hexapod robots become damaged, they can use their own knowledge of how their body works to find a solution. The hexapod robots are also programmed with childlike curiosity. In other words, they are always asking questions and looking for the answers. The whole process just takes about a minute for the robots to overcome the damage and continue to carry out the task. 【解题导语】 如今，机器人无处不在，它们被应用于各个领域。科学家们正在研发一种新的技术，使机器人遭到损坏时能够迅速做出改变并继续执行任务。 1．What do we know about robots?

You step into your circle, twopassenger aircushion car, press a series of buttons and the national traffic computer notes your destination, figures out the current traffic situation and signals your car to slide out of the garage. Hands free, you sit back and begin to read the morning paper which is flashed on a flat TV screen over the car's dashboard. Tapping a button changes the page. The car speeds up to 150 mph in the city's countryside，and then hits 250 mph in less builtup areas, driving over the smooth plastic road. You fly past a string of cities, many of them covered by the new domes (圆屋顶) that keep them evenly climatized all year round. Traffic is heavy, typically, but there's no need to worry. The traffic computer, which sends and receives signals to and from all cars on the road between cities, keeps vehicles at least 50 yds apart. There hasn't been an accident since the system began. Suddenly your TV phone buzzes. A business partner wants a sketch of a new kind of impeller your firm is putting out for sports boats. You reach for your case and draw the diagram with a pencilthin infrared flashlight (红外线闪光灯) on what looks like a TV screen lining the back of the case. The diagram is sent to a similar screen in your partner's office, 200 miles away. He presses a button and a fixed copy of the sketch rolls out of the machine. He wishes you good luck at the coming meeting and signs off. Ninety minutes after leaving your home, you slide beneath the dome of your destination city. Your car slows down and heads for an outercore office building where you'll meet your colleagues. After you get out, the vehicle parks itself in a garage to await your return. Private cars aren't allowed inside most city cores.
