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.

As I look back on it now, I realize it was kind of silly of me to be so worried when Daddy was really just late. I waited every night for Daddy whom I followed around everywhere.

　 That day, I stood at my        place by the door, waiting for his return from work.

　 After standing there for a while, I began to      where Daddy was. I ran into the kitchen and asked Mummy     ,“When is Daddy coming? ”

　 “ Soon, honey, ”Mummy replied distractedly (心不在焉的) because she was following a difficult recipe(cookbook) for dinner.

　　I ran back to the door for I knew that Daddy was coming and that I wasn’t standing there for nothing, I began to read the words from my favorite books.

　　Tired of that, I went back to the kitchen to ask Mummy again but        I could open my mouth, she handed me a My little Pony coloring book. She said: “I’m busy, Daniel. Go and        a pretty picture and I’ll hang it on the fridge. ”

　　I went back to the door, put my book and crayons (蜡笔) down, then went to get my mini chair to sit in. After a while, the           became a pink-and-purple artistic wonder.

　　Soon I           with relief (放心) as I heard the sound of the garage door        and Daddy’s car driving in. I heard him turn off the engine and open and close his car door. The next thing I knew was that the door opened and there stood Daddy. I stood up and         my arms . I hugged him tightly and whispered, “I love you”.

　　As I sit at the computer finishing this story, I know Daddy will be home soon. I still        when he’s late. I still go to greet him when he arrives. And I still tell him I love him.
