There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by “feedback”(反馈). Information about what is happening is feedback into the robot to tell 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 human beings in two ways. They work and they have feedback.
In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot’s “arms” and “hands” through each part of the job.
The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such job as handling radioactive materials.
【小题1】In this passage the author tells us that .A．robots are very popularB．there are various kinds of robotsC．we see robots only at certain timesD．robots can be easily controlled【小题2】What does the author seem to inform you about robots?A．They should be greatly improved.B．They will probably take over in the future.C．They are very helpful and useful to humans.D．They are machines that break down a lot.【小题3】The author says that in industry .A．robots break down a lotB．robots can do many jobsC．robots only get in the wayD．robots sometimes cause troubles【小题4】The fact that a robot never gets bored doing the same job means that .A．it is very much like human beingsB．it can do boring jobs for peopleC．it will never bore peopleD．it will work much better than human beings【小题5】The robots used for scientific research .A．are not very cleverB．are very cheapC．are very bigD．are very costlyA

(答案→)A 解析：本文介绍了机器人的特点以及它的优点。【小题1】事实细节题。由There are robots all round us得出答案A答案正确。【小题2】推理判断题。从 They work quickly and do not make mistakes …And they never get tired. So robots are very useful in factories(机器人工作快…不会觉得累)可知对人类有很大的帮助，故答案选C。【小题3】事实细节题。由 They can be taught to do many different jobs可知答案选B。【小题4】语义理解题。They do not get bored doing the same job over and over again(机器人对做同一工作从不会感到厌烦)，此义与B 项较吻合。【小题5】事实细节题。由原文The expensive robots are used in scientific research 可得知答案为D。

就是这个解释
