What comes into your mind when you think about robots(机器人)? Do you imagine armies of evil metal monsters(怪物)planning to take over the world? Or, perhaps of mechanical men who have been created as guards or soldiers by a mad genius? Or maybe you think of man-like robots who act, think, and look like human beings. In fact, robots like these have more to do with science fiction films(科幻电影)than with real life. In the real world robots are machines that do jobs which otherwise have to be done by people. Robots either operate by themselves or under the control of a person.
In a car factory, for example, robot machinery can put together and paint car bodies. On the sea bed, remote-controlled(遥控)underwater machines with mechanical arms can perform tasks too difficult for divers. Robot spacecraft can explore the solar system and send back information about planets and stars.
Many robots have computer brains. Some robots are fitted with cameras, sensors, and microphones which enable them to "see", to "feel", and to "hear". And some robots can even produce electronic speech.
All this does not mean that a robot can think and behave like a human being. Present day robots have to be programmed with a good deal of information before they can carry out even simple tasks.
The robots in science fiction films and those in real life differ mainly in ________ .
A. mentality B. appearance C. material D. size
What can robots do in the real world?
A. They have the ability to control the world.
B. They can behave like human beings.
C. They can help us do a lot of work.
D. They can think by themselves.
Which of the following statements is NOT true about robots?
A. They are as creative as human beings.
B. They can help manufacture cars.
C. They can explore outer space.
D. They can "see" and "hear".

What should I eat for breakfast? Who should I go out with on weekends? What should I do if I miss the bus to school? What colleges should I apply for? Again and again Chinese kids ask these questions to their teachers and parents. They can’t make their own choices.
Kids in America would be very surprised to hear how much Chinese children depend on adults. When they are ten years old, kids decide what clothes they want to wear and buy. By twelve they know what classes to take for middle school. Thirteen years old is the beginning of being what Americans call a “teenager”. Now the child is up to almost all his / her decisions. Finally at sixteen the kid usually gets a car from his / her parents.
Why should kids be independent? Think about it. After high school most of us will be by ourselves. Will our parents be able to tell us what to eat for breakfast in college? Can our teachers decide what we should do at work?
Making our own choices can be quite hard and scary. But we can start with making small choices, and then slowly make bigger and more important choices.
