Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

Sometimes people come into your life and you know at once that they were sure to be there. They serve some sort of purpose, teach you a lesson or help find out who you are or who you want to become. You never know who these people may be: your classmate, neighbor, teacher, long-lost friend or even a real stranger. But you know that every moment they will affect (影响) your life in some serious way.

Sometimes things happen to you. At the time they may seem terrible, painful (痛苦的) and unfair. But later you realize that without getting over those difficulties you would have never realized your further ability and strength. Everything happens for a reason and nothing happens by chance or with good or bad luck.

The people you meet affect your life, and the successes and failure (失败) you experience, create who you are. Even the bad experiences can be learned from. In fact, they are probably the most poignant and important ones.

Enjoy every day even every moment and take from it everything that you possibly can, for you may never be able to experience it again. Talk to people you have never talked to before, and really listen. You should set your sights high, hold your head up,tell yourself you are a great one and believe in yourself.

You can make your life anything you wish. Create your own life and then go out and live it.
