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.

Taking part in charity is not just for adult people. Kids can do it too! Melvin Sheppard, 14, an American student, has done charity work for 8 years. He has also encouraged his classmates to join him.

Melvin studies at William Allen Middle School in Philadelphia. Recently, he collected $ 1,500 by himself and $487 from his classmates to donate to Cooper University Hospital.

Melvin was born nine weeks premature (早产的) in Cooper University Hospital, weighing 2.6kg. His father told him how Cooper saved his life, so he feels thankful to the hospital.

Melvin's classmates joined him once they found out about his kind behavior. Their teacher, Michael Bemer, also held a class with them about helping others. "It wasn't really about the money," Bemer said. "It was about the fact that they were doing something good."

"It feels great, helping someone that I know." said Jordan, Melvin' s classmate. Melvin's neighbors also helped out.

Since Melvin was 6, he and his parents have given money to Cooper University Hospital every year. This year, Gray E. Stahl, the head of the hospital, went to Melvin's school to accept the money.

The money goes to a part of the hospital that helps about 500 young patients every year.

"When they leave, we call them graduates," Stahl said, "my workmates and I are pleased when our graduates and their families do well, like Melvin and his family."
