Have you ever thought of taking a train and having an adventure (奇遇)？Riding the train can be a real adventure.That is how I feel every time I take Amtrak.I often take a four?hour trip to visit my children.Every time I take this trip I never know what will happen.

Last week when I was on the train and over an hour into the train ride，there was a man sitting by himself in the back of the train carrying on a mobile phone conversation— in another language.It was loud and disturbed most of the people on the train.I think it was annoying.

Fortunately I sat next to a wonderful old lady who was taking a two?day trip by train.She said her two daughters were distraught at the thought of her driving for three days to reach her home，although she had no trouble driving.The train ride was the only choice for her.She loved to look out of the window and watch the world go by on the train.

She was fun to talk to and asked me when my children started being parents.That is a very good question.Both of us are old and have children.She asked that same question from time to time.

There are always many people on the train from all walks of life，different countries，and many languages.Riding the train is a great way to increase your knowledge and take in all kinds of cultures.If you get hungry，you can buy food in the food car at any time.If you need to use the restroom there is always one available.

It sure beats driving the car，which has to stop for food and restrooms.And it is better than taking the bus.

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.
