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 jobs as handling radioactive materials.

Public schools in Washington, D.C. provide students with musical instruments for free. When something goes wrong with an instrument, Charles West and Larry Jernigan do the repairs. Both men approach their work with a passion(激情). For them, it’s important that students have a joyful experience with music.
The two have worked together for almost 20 years. This year alone, they’ve fixed about 450 instruments. Both men are musicians and music lovers, so learning to do repairs came naturally.
“I have been a musician all my life.” says West. “I played in an orchestra here in the city. I majored in music in college. I played in an army band.”
Jernigan’s musical interests are varied. “I was formerly trained in the piano and guitar. The alto sax, and the flute, I picked up while working here.”
In addition to fixing instruments, the two also go to schools to instruct teachers and students on how to make minor repairs on their own.
West believes if children start early and stay involved with music, it enriches other areas of their lives. “I see that in other kids. I see it in myself. I have seen it hundreds of times and it works,” he says. “They learn teamwork. They learn patience and respect.
But West has concerns about the future of music in the electronic age.
“This instant age has taken away from the sit-down, the patience. And to learn to play an instrument, it takes patience, it takes diligence, it takes time.”
Being able to enjoy music on the job is one of the benefits of the job. Both men agree their best rewards are the students’ performances.

Most Americans enjoy moving from place to place. For example, they often drive their cars 120 to 160 kilometers away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one person in five lives in a place for more than five years. One may be born in one city, and go to school in another. He may finish his middle school in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from one job to another, which is called “job-hopping”, is a very common practice in the United States. Job-hopping is good to workers, because every change of a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives bosses the chance to get new ideas and skills that different people bring to their companies and factories.
