题目内容

Computers can injure (伤害) 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 happen 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 more than 50 centimeters from the screen. Don’t forget 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 (肘) as high as the keyboard.
3) Stop sometimes 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 shouldn’t bend your back when you sit. The top part of the screen should 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 half an hour and exercise your arms, legs and neck.
Enjoy your computer, but use it safely.

Many young people these days are interested in extreme sports, which mean very dangerous activities that need speed, height, or a high level of physical exertion(努力). Bungee jumping, snowskating, parkour and surfing are very popular extreme sports, but mountain climbing might be the first.
In 1985, two British young men, Joe Simpson and Simon Yates became the first west faces to climb the 6344-meter Siula Grande in the Andes(安第斯山脉). On the way down, Simpson fell and broke his leg, then he slipped(滑) down and lost connection with his friend. Yates had to get for help. Simpson fell more than 100 feet and landed on a bridge of ice. Finally he crawled(爬) for three days without food or water, until he reached the camp.
On April 26, 2003, when Aron Rolston was climbing alone in Utah, his arm was caught under a 360-kilo rock and he couldn’t move. After five days of waiting for help, the 28-year-old American ran out of water and finally he cut off half his right arm with a small knife to free himself. He also bandaged(包扎) himself in order not to lose too much blood. In 2004, he wrote a book named Between a Rock and a Hard Place. “In this book,” Aron said, “I want to tell the readers the importance of making good decisions, and of being in control of one’s life.”

小题2:Did Simpson and Yates’s disasters happen on the way up the mountain?
小题3:How did Simpson get back to the camp?
小题4:What did Aron do to save himself when he ran out of water?

Learn to relax. Overwork is the main reason why so many students feel tired and stressed. Cut down some of the jobs you need to do each day so that you can only focus on the most important things. Leave time for activities that are relaxing and fun. This might mean reading a good book, listening to the music, going for a walk or taking a relaxing bath.
Get a good night’s sleep. Getting enough sleep will help you keep your body and mind in the best form. If you stay up late and need to get up early for school the next day, you may not be able to concentrate on the things you need to do.
Exercise regularly and eat well. Don’t rush through your meals. Eat less junk food or fast food. Eat healthy food instead.
Get to know pleasant people. Some people are optimistic, while others not. Choose optimistic people as your friends and spend more time with them and you’ll be as happy as them.
Learn to be calm when you face any problem. Find out the best option from those that are in your mind. Knowing that you are able to solve problems is a good way to build up your self-confidence.
Have a happy attitude. Your attitude decides the way you see things. Is your cup half full or half empty? Learn to think more positively(积极地) about the difficulties you face.
