If the only sports you do are dancing your fingers across your keyboard, you could be in serious danger of more than just becoming overweight and out of shape.
Do you often 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, you are more easily harmful by the hazard(危险).
We have got so used to using computers that we often neglect(忽略) to think of them as dangerous sources of harmful radiation. A safe amount of radiation is 25V/m(Volts/meter). Do you want to guess how much our personal computers give off?
Keyboard： 1000 V/m
Mouse： 450 V/m
Monitor： 218 V/m
CPU： 170 V/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 or 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 50 cm 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?

Anger is a kind of feeling. Many things can make you angry. When your teacher gives you too much homework, when your team loses an important game, when a friend borrows your favorite thing and then breaks it, you may get really angry.
Usually, your body will tell you when you are angry. For example, you breathe faster, your face turns red, and you may want to break something or hit someone, but sometimes, you hide your anger. For example, you may hide it in your heart. The problem is that if you do this, you may get a headache or your stomach may hurt.
In fact, it’s not good to hide your anger, and it’s normal for you to get angry sometimes. But anger must be let out in the right way, without hurting others or yourself.
When you get angry, you can talk about it with other people. It’s helpful to talk about your anger with an adult, such as parents, a teacher, etc. When you talk about anger, those bad feelings can start to go away. Here are some other things you can do when you start to feel angry: talk to a good friend; count from 1 to 100; give someone a hug; go for a bike ride; think about good things, etc.
Remember that how you act when you are angry can make everything better or worse. Don’t let your anger control you.
