The place of the family computer may turn into a hot argue as your children get older. Whether you have one computer in the house or five, you should think the following things as you make a final decision.

There is a certain number of danger if you allow your children to have a computer with Internet in their rooms with no pa­rental direction. They may share improper information and chat with strangers if they know that no one will be watching.

This does not mean that you cannot allow your children to have a computer in their rooms. Think allowing a computer without Internet. This is especially useful for teens who use the computer for creative projects, playing video games and listening to music. Keep in mind, however, that it is possible that your kids are more skilled at computers than you are and may re­move any blocks you have in place.

Computer Use

The way your family computers are used will play a role in deciding where they should be placed. A machine used only for homework will need to be in a quiet place where there is low traffic. One used for chatting online can be in the room where most of the family spend their time. If Mom and Dad use a computer for work, those needs will also have to be thought.

Space

Space must also be considered in computer placement. The computer will need electricity, plenty of desk space and a spot away from this bright light of windows. You will not want it placed in a room where your kids may be noisy.

1.The text is written for__________.

A. teachers 　　 B. parents 　 C. students 　 D. children

2.Which of the following might be a danger to children?

A. Chatting with strangers. B. Doing their homework.

C. Playing video games. 　　　 D. listening to music.

3.What might be the best place for family computers used by students?

A. Beside a window. 　　 B. Near the door.

C. At the corner. 　　　　 D. In front of a TV set.

4.Which world can be put in the empty box?

A. Safety. 　　 　　 B. Difficulty.

C. Friendship. 　 D. Attention

5.What can we learn from the text?

A. A child should not be allowed to use a computer.

B. A child should not be allowed to get online.

C. A computer takes up a lot of desk space.

D. Many things decide the place of family computers.
