Yesterday I was shopping for a few items(物品).With nothing to do at home, my son, who just left university, was ready to go together with me.

  As I pushed the basket towards the register(收银机),I checked my items to see how many I had, thinking I might go to the Express Line(快速通道)where the sign said“Ten items or less”.

  I started to go to that line and my son said,“Mon, you have twelve items!”I said,“You know, but they’re close.” He said,“Why are you in such a hurry to get home? You should go to the Regular Line because you have over ten items.”

  Knowing he was right. I agreed and then pushed the basket to the next line. So I was waiting for my turn there and I was just removing my items from the basket to pay for them when a young man came up behind me in line with two items.

  I just left the Express Line because I had too many and now I really wanted to get finished. Again, my son came up.“Mom, he has only two items and the Express Line is very long now. Won’t you just let him go first?”I agreed, and the young man smiled widely and thanked me several times.

  It felt good to be with my son and have him remind me not to live a hurried life. Do what’s right and also be kind. I really take pride in him.

 “Tom? Are you in bed yet?” called Mrs. White. There was no answer. Mrs. White put down her book and went to her 14-year-old son’s room. Tom was sitting in front of a right computer screen (屏幕) on which a colorful dragon (龙) jumped and shouted.

　　“Oh, Tom! You’re still playing on that computer. You must stop now, it’s half past eleven. If you don’t go to bed soon, you’ll be very tired tomorrow.” said Mrs. White.

　　“But I’ve nearly beaten the dragon.” said Tom. Mrs. White could see the excitement (激动) on her son’s face. She sat down beside him.

Let me show you!” Tom began tapping (敲打) keys on the keyboard (键盘). The screen changed in answer to his orders (命令).

  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.
