Many young people can use the computer，but few of them know how to look after them．Remember the following when you use the computer．
Keep your computer in a cool, dry room．Too much or too little heat is bad for computers．Damp is also bad for them．Most computers work best at a temperature of 5-30 degrees centigrade．
Do not let people smoke cigarettes near your computer．Smoke is very bad for many parts of a computer and can cause many problems．
Do not eat or drink when you are near your computer．Pieces of food and a little water in the keyboard call also cause many problems．
Make sure that the keyboard and tile screen are the correct height for you．If they are not correct，you'll 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．
