and break your arms, it happens very quickly. But computer injuries happen slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at
least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes
a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light
will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into
your eyes.
Your hands and wrists
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundr-eds of
times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on some-thing. 2)
Keep your elbows (肘) at the same height as the keyboard. 3) Stop sometimes and exercise your hands, wrists
and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your
back or your neck. So you should sit with your back straight. The top part of the screen should be in front of
your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor.
If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.

| Nowadays more and more people in the world are getting fatter, which troubles them a lot. In the past 25 years, the number of the people with obesity (肥胖症) in Europe has doubled. Experts say that it has a lot to do with our eating habits. Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than meat and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite (食欲). It"s important for us to eat our meal at the same time each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges often decided whether a man was tell-ing the truth by giving him some dry bread. If the man could not swallow (呑) the bread, it meant that he wasn"t telling the truth. A man who is worrying something has difficulty in swallowing anything dry, because he loses his appetite. | ||||||||||||||||||||||
