“I sometimes get up at three or four in the morning and I surf the net.”
“I often check my e-mail forty times a day.”
“I often spend more than three hours during one time on the net.”
“I spend more time in chat rooms than with my ‘real-1ife’ friends.”
Do you know any people like these? They are part of a new addiction(瘾) called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control of the time they spend on the Internet
For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.
Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family.
Is ‘surfing the net’ a hobby or an addiction for you? You may have a problem if you have these symptoms(症状):
●You do not go to important family activities or you do not do school work because you like to spend hours on the Internet.
●You can’t wait for your next online time.
●You plan to spend a short time online, but then you spend several hours.
●You go out with your friends less and less.

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.

Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).
The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.
Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.
Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

You must exercise your eyes every day. Blink (眨眼) yours eyes at regular periods, which makes the eyeballs watery, and gives them a good wash.
We use our eyes in many unnoticeable and wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can cause damage(伤害) to your eyes. Don’t read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes. Too much reading, writing, watching television or working on the computer can also cause eye tiredness.
Remember to always take care of God’s most beautiful gift to you. Your life will be very colorless without your eyes.
