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?

A．根据短文内容简要回答问题。

1. Which is safer, using a desk computer or a notebook computer?

2. Which of the nine ways mentions diets?

Bicycles in China

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to school, shops and anywhere else.

Compared(与……比) with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles. Second, bicycles are small enough to park anywhere, while cars need a larger piece of land to park. What’s more, with lower speed, bicycles are safer than cars.

However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others’ safety. So they ride too fast. During rush hours, too many bicycles may cause traffic jams. We still have a long way to go to solve the problem.
