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 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.

An Unforgettable Person

There are a lot of things in my mind. But there’s one thing that impressed me most.

The fight against NCP has lasted for several weeks. During the fight, doctors and nurses are like heroes—they protect us and they fight for us. My aunt, a doctor, moved me a lot. For the past years, my aunt was just an ordinary relative for me. But the decision she made on Jan. 23rd changed my thought completely—she asked to go to Wuhan to help the patients there. Though her daughter is only three years old, she decided to leave for Wuhan. For her, it is the thing that she must do. I was really moved. I want to tell my aunt that I am proud of her.
