III. Further reading

Read the passage and answer the questions.

       We are already familiar with computers—computers work for us at home, in offices, and in factories. But it is also true that many children today are using computers at schools before they can write. What does this mean for the future? Are these children lucky or not?                                                              

       Many people who do not know about computers think of them as machines that children play with. They worry that this will affect children’s education and life experience. They think that children won’t learn about the “real world” if they rely too much on computers.

       But people who understand more about computers say that computers can be very good for children. A computer can help them to learn about the real world more quickly, as well as learn what they want to learn and think for themselves. And for the future, don’t we need people who can think clearly, who know how to get information quickly and use it well? What do you think?                                                  

 

1.  “To be familiar with” means to ____.

A. know nothing

B. know about

C. dislike

D. like

 

2. In the sentence “Many people who do not know about computers think of them as machines that children play with” , “them” refers to computers.

 

3. What can computers help children do?

  To think clearly, to get information and to use it well.

 

IV. Post reading
