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 (肘部) 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(前臂), wrists, hands and the upper(上部) 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.

Sometimes you feel busy and worried. 你可能有许多事情要做,时间却不够。You may wonder, “ Where does time go?” Here are some ideas to help you make use of it and find more free time to enjoy your life.
Plan ahead of time. It’ s necessary for you to make a plan at the beginning of a week or a day. Think of what you really need and don’t need to do. Spare(匀出)some time to have a short rest and look back on what you’ve done. You may have a sense of success.
Say no to yourself. If you are not excited about attending(出席)a social activity, then don’t go. 呆在家里休息。If you plan to go to a supermarket but it is raining heavily, why not stay inside? It’s fine to change your mind and do your shopping another day.
Change your pace(节奏). If you usually go shopping on Saturday, choose a weekday night to go instead. The stores are less crowded on Wednesday evening than Saturday afternoon. You can feel better if you regard your way home as taking a relaxing walk after supper.
Focus on(关注)simple pleasures. When your day’s work is done, it’s time to get yourself relaxed. A pleasant bath, a cup of coffee or a gentle song can be enough. Although expensive relaxation is nice, when you focus on simple pleasures, you’ll get more.

Internet is educational . Many people think children should be allowed to surf the Internet as they wish . In this way ,they can look through different subjects on different kinds of websites according to their own interest . But in my opinion ,children should always be watched while surfing the internet .
Many websites have information and pictures that children should not see .There are many things that children don’t understand .All of these may have some bad influence on children ‘s development . Also , it is dangerous to let children use chat rooms by themselves .Many parents tell their children not to talk to strangers on the street , so they should be careful of whom their children talk to on the internet,too . What’s more , sitting in the front of a computer for a long time isn't good for children’s eyes , so parents should monitor(监视) the time that children spend on the internet .
In a word ,children should be kept away anything that could be bad for them . I strongly believe that it is necessary for parents to watch their children when they use internet .
Is the Internet educational all the time ?
What do the parents tell children to do when they meet strangers on the street ?
Why shouldn’t children sit in front of a computer for a long time ?
Who can help children stay away from the bad influence on the Internet ?
What does the writer want to tell us in the passage ?
