结构推理 Directions: Read the following passage carefully and give brief answers to the questions. Questions 1 to 5 are based on the following passage. There are robots (机器人) all around us. Some do very difficult jobs like flying airplanes and driving subway trains and some do one simple joB、 When an automatic washing machine is turned on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by feedback (反馈). Information about what is happening is fed back into the robot to tell it what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like people in two ways. They work and they receive feedback. There are robots all around, making our lives easier. Some of them, like the pocket calculator, can work much more quickly than human beings can. And they seldom make mistakes. In some ways robots are better than people. They work quickly, but do not make mistakes. They do not lose interest doing the same job over and over again. And they never get tireD、 Robots are very useful in factories. They can be taught to do many different jobs. Their electronic brains must be shown how the job is done. A person moves the robot’s "arms" and "hands" through each part of the joB、 The robot's brain remembers each move. Then the robot is put to work on its own. If the robot's hand stops working, or if something gets in the way, it cannot do the next part of the joB、 So it stops and signals for help. Then a human engineer attends to the problem. The most "intelligent" robots can move and see. Their eyes are cameras. Their metal fingers can feel shapes and even find out how hot and cold objects are. These robots have computer brains linked to their eyes and fingers to control their actions. 1. What happens when an automatic washing machine is turned on? 2. In what ways are robots like people? 3. Why do some robots work better than people? 4. How are robots taught to do a job? 5. What are the qualities of the most intelligent robots?
