小題1: If 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(輻射) 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).
小題2:We have got so used to using computers that we don’t often think of them as dangerous sources(來源) 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(過濾器) 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(空氣流通的).
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?

小題1:根據(jù)短文的列舉的輻射量★ Keyboard: 1000 V/m       ★Mouse: 450V/m    ★Monitor: 218 V/m ★CPU: 170V/m ★Notebook computers: 2,500 V/m故填Using a desk computer is safer.

It seems to be strange to you there is a blind spot (盲點)on the eyes. Here is an interesting experiment (實驗) that can make something disappear(消失) when one eye is open.
Make a card which is as big as a postcard, and write two English letters L and R on it. Write L on the left and R on the right. First, hold the card about 80 cm(厘米) away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.
Why does the letter disappear? It is because there is a blind spot on the eye. When the image (影像) of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.
小題1: Where should we write the two letters?
小題2:Which letter should be written on the left?
小題3:Which eye do you close when R disappear?
小題4:What will happen if the image (影像) of the letter falls on the blind spot?
小題5:.Do all people know that there is a blind spot (盲點)on their eyes?
