Question

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.    小题1:  You have no mobile phone. What should you do? Well, next time take a GPS with you. This invention may be able to help you.    小题2:   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.    小题3:   We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are.    小题4:
Some people think that in the future the GPS will be as common as the mobile.    小题5:   here are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

A:It is a device(装置) which uses satellites to find the user’s position.
B: For example, in a city they can tell you the name of the street.
C:It is night and it is cold.
D: There are three parts to the Global Positioning System.
E: You can hold it in your hand, or put in your pocket.
F:They are becoming cheaper and more and more accurate(精确的).
