三点一测快乐周计划系列答案Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

When you are about to do something brave, a cheerful wish of “Good luck!” from a friend can be helpful. But if you think you need lots of luck, what else might you do?
In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer.
Have you heard the saying “When you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn’t happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true.
Maybe you have heard of the lucky rabbit’s foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit’s feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, “Depend on the rabbit’s foot if you will, but remember it didn’t work for the rabbit!”
People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole of good luck!

3.British people try to catch 12 falling leaves because ______.
