问题     Robots do make mistakes sometimes. But they are not responsible for the mistakes. In one automobile factory,, for example, the doors on more than I ,000 cars were welded shut. A human had given the robot’s computer brain the wrong instructions. ’When robots get the correct instructions, their work is good and fast. A company in Florida, for example, uses robots to build small communicating devices. The robots put about 130 tiny electronic pieces into each device. The factory can produce a device just two hours after it receives a request for one. The company says it would take almost one month to produce a device in a normal factory with human workers.
    What is the future of robots? The goal of scientists is to create a true humanlike robot. Some experts have described this robot of the future as one that can act independently with the physical world through its own senses and actions. Humans have the ability to see, bear, speak and solve problems. Engineers have build robots that have one or two of these abilities. But it takes a number of big costly computers to make the robots work.
    The biggest problem in creating a humanlike robot is copying human intelligence. The way the human mind works is almost impossible to copy. A simple computer can do mathematical problems far be yond the ability of even the smartest human mind. But the human mind is better than a thousand super computers at speaking, hearing and problem-solving.  Several American and Japanese companies are working to develop the senses of sight and touch for robots. The development of these senses will make robots much more useful.
    However, the most important human ability—and the most difficult to copy—is problem-solving. An intelligent robot must be able to change the way it acts when it faces an unexpected situation. Humans do it all the time. Computers must do it for robots. This means computers must have a huge base of information about many things. They must be able to find the information in their systems quickly. And they must make choices about how to act. So far, this is beyond the ability of computers.
    Will it always be so? Probably not.  Computers have improved at an unbelievable speed.  In 20 years, computers have become 1,000 times more powerful. Scientist expect this rapid improvement to continue. Computers of the future will have the power to operate more humanlike robots.
The robots in use now can do many jobs ______.
选项 A、independently through its own senses and actions
B、according to the instructions from human workers
C、according to the instructions from computer brain,
D、according to the instructions from communicating device
答案B
解析 机器人是由电脑支配的，而电脑当然是靠人脑发出的指令而进行工作的。A项是科学家所描述的未来的机器人，所以不正确。故选B。
