of more than just becoming fat!
Do you feel sleepy, like something is weighing down on your head? Do you feel forgetful? Do you
sometimes feel uncomfortable up and down your neck and lower back, and you can't explain why? Do you get
sick often? It could be radiation (辐射) from your computer causing it. If you spend three hours or more a day
in front of a computer, (and at this point, who doesn't?) you are more easily harmed by these hazards (危害).
We have got so used to using computers that we don't often think of them as dangerous sources (来源)
of harmful (有害的) radiation. A safe amount radiation is 25 V/m (Volts/meter). Do you want to guess how
much our personal computers give off?
★ Keyboard: 1000 V/m ★ Mouse: 450V/m ★ Monitor: 218 V/m
★ CPU: 170V/m ★ Notebook computers: 2, 500 V/m
Ways to Protect Yourself from Harmful Computer Radiation:
1. Decorate your desk with cactus (仙人掌) plants, they take in radiation.
2. Drink two to three cups of green tea a day and eat an orange daily. The vitamins in tea leaves and
oranges protect us from radiation and keep our eyes healthy as well.
3. Use a screen filter (过滤器) for your monitor.
4. Avoid having metal objects nearby on your desk.
5. Put the back of the computer to the wall. Most of the radiation comes off the back.
6. Keep your monitor at least 50cm away from your face.
7. Keep your computer rooms ventilated (空气流通的).
8. Eat healthily-especially fruits and vegetables.
9. Don't fall asleep on your computer. Turn it off if you have to rest nearby. The ways above are useful,
why not have a try at once?
A. 根据短文内容简要回答问题。

Most people want to be happy, but few know how to find happiness. Money and success alone do not bring lasting happiness. Aristotle, a Greek thinker, said, “Happiness depends upon ourselves.” In other words, we make our own happiness. Here are a few suggestions to help you be happier.
The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future —for example, getting into college or getting a good job —that we fail to enjoy the present. You should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends often live happier and healthier lives. Another secret to living a happy life is to be active, and have hobbies where you forget your problems and time. Many people experience this dancing, or playing a sport, such as swimming. You can forget about your problems, and only think about the activity. Finally, many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier, do good things for someone. You can help a friend with his or her studies, go shopping to buy food for an elderly person, or simply help out around the house by washing the dishes.
