Computers can help us in many ways, but they cannot think or do things on their own. Humans have to feed them with information and tell them what　　 to do. They cannot come up with any new information, but they can save much time and work. For example, all the information and the office files (文件) can be stored in a computer’s “memory”.

The first computers were huge and expensive. They filled up almost the whole floor of large offices. Later, scientists found ways to produce cheaper and smaller computers. They invented chips (芯片) which made it possible to store more information in less space.

Today, computers are not only cheaper, but also more compact. They can just be placed on top of an ordinary writing table. They can even be carried from place to place easily. Computers are not only used in offices by companies, but are used at home by families who can afford them.

Robots are only moving parts controlled by computers. A robot can do the same work as a person for 24 hours without complaining or getting tired.

In Japan and some places in America, robots are used in factories to assemble (装配) cars. As computers become more and more common in businesses and factories, people fear that one day computers and computer-controlled robots will put human workers out of work.

1.What were the first computers like?

A.Small and cheap B.Huge and expensive C.Small and expensive D.Huge but cheap

2.The underlined phrase “more compact” can be replaced by “　　”.

A.larger B.brighter C.smaller D.heavier

3.Which of the following is NOT true according to the passage?

A.Robots are controlled by computers. B.Robots can do the same work as humans.

C.Robots do not get tired of working. D.Robots are used to sell cars in China.

4.Humans fear that one day computers and robots 　　.

A.will be busier than humans B.will be cleverer than humans

C.will make humans jobless D.will make humans become blind

5.The BEST title for this passage can be 　　.
