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. 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(环绕…运行) the Earth. The receiver contacts at least four of the satellites and calculates 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. Also there will be new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost anywhere.

In the video, young people from 20countries along Belt and Road Routes(一带一路)were asked to name great inventions that had influenced their lives in China. The following is what they said:

Justin

I’m from Romania. China is really a great country and its high-speed railways are very fast, convenient and tidy. It takes me only about 6 hours from Beijing to shanghai by train. It saves a lot of time and it’s cheaper than airplane. I wish we would have high-speed railways in our country someday.

Yala

I’m from Nepal. I always go out by bike.Bicycle-sharing system allows people to borrow a bike from point “A” and return it at point “B”. It’s not only cheap but also a low -carbon and healthy way of life. I like it very much .

Archana

My life in Beijing is quite different from that in India. Here in China , I seldom take money with me when I go out. I can pay for almost every-thing by Zhi Fu Bao. Oh, it’s amazing. However. In India , if you don’t take wallet with you, you’ll be in a tough spot.

Bond

You can find many wonderful things that we don’t have in Thailand. We don’t have Alipay or other online payment Apps with which I can go shopping without stepping out of the doors.I hope I could bring them back to my country!
