3If the only sports you do are dancing your fingers across your keyboard, you could be in serious danger 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).
4 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.
10.The ways above are useful, why not have a try at once?

Today, there are many problems between parents and children. Many people always ask, “ Why do we often argue(争论)?”
Parents show their love to children in different ways. They cook nice food, buy new clothes for them. They also care about their studies. Parents always ask “ You must work hard”, “You should do your homework”, “Why not do homework for your exam?” all the time.
When children get bad marks, their parents get very angry. They stop their children watching TV, playing games or going outside until they are good at their studies.
Why? Most families have only one child. The child is the hope of the family, they want the child to be the best.
Many children want to do things themselves. They want to do many unusual things that parents dislike. They like pop music, basketball and other new things. They enjoy surfing on the Internet and playing QQ games. They spend a lot of time chatting online and listening to the QQ music. In their parents’ eyes, these are a waste of time.
