    Many young people can use a computer, but few of them know how to look after it. Remember the
following tips when you use a computer.
    Keep your computer in a cool, dry room. Too much or too little heat is bad for computers. Damp
(潮湿) is also bad for them. Most computers work best at a temperature of 5-10 degrees centigrade
(摄氏度).
    Do not let people smoke cigarettes near your computer. Smoke of all kinds is very bad for many parts
of the computer and can cause many problems.
   Do not eat or drink when you are near your computer. Pieces of food or drops of water on the keyboard
can also cause many problems.
    Make sure that the keyboard and the screen are the correct height for you. If they are not correct, you
will get backache.
   Make sure the screen is the correct distance from your eyes. If you wear glasses, make sure these
glasses are correct for using with the computer. Some people use a different pair of glasses when they
use a computer.
    Keep your screen clean and do not have it too bright. A dirty screen can hurt your eyes. A very bright
screen can also be bad for your eyes. If you can afford one, buy a computer screen. It will be better for
you than using the screen of a TV set.
    Never use any software (软件) that you don't know whether they are clean or not. You must be careful
because some software can bring viruses (病毒) into the computer. If your computer has viruses, it can't
work or even breaks down.
