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 (and at this point, who doesn't?), you are more easily harmed by the hazards.
We have got so used to using computers that we often neglect to think of them as dangerous sources of harmful radiation. A safe amount of radiation is 25 V/m (Volts/meter). Do you want to guess how much our personal computers give off?
Keyboard: 1000 V/m
Mouse: 450 V/m
Monitor: 218V/m
CPU: 170V/m
Notebook computers: 2,500 V/m
Ways of Protect Yourself from Harmful Computer Radiation
1 Decorate your desk with cactus 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.
3Use a screen filter 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 .
8Eat 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?
Remembering names is an important social skill. Here are some ways to master it.
When you hear a person's name, repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound you are forced to.
You can let other people help you remember their names. After you've been introduced to someone,ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort you're making to learn their names.
To be honest to say that you can't remember someone's name can actually make people relaxed. Most of them will feel sympathy if you say, “I'm working to remember names better. Yours is right on the tip of my tongue. What is it again?”
Consider going early to meetings, parties and classes. Sometimes just a few people show up on time. That's fewer names for you to remember. And as more people arrive, you can hear them being introduced to others -- an automatic review for you.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
A. Limit the number of new names you learn at one time. B. Recite and repeat in conversation. C. Tell the truth that you don't know. D. Remember names as many as possible E. Go early. F. Ask the other person to recite and repeat. |
