At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars．Our own planet, Earth, is becoming more and more crowded and polluted．Luckily, we can start again and build a better world on Mars．
First of all, transport should be much better．At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months．However, by 2100, spaceship can travel at half the speed of light．It might take us two or three days to get to Mars! Secondly, humans need food, water and air to live．Scientists should be able to develop plants that can be grown on Mars．These plants will produce the food and air that we need．However, can these plants produce water for us? There is no answer now.
There is a problem for us to live on Mars．Mars suck（吸力） us much less than the Earth does．This will be dangerous because we could easily jump too high and fly slowly away into space．To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better than that on Earth in many ways．People will have more space．Living in a large building with only 10 bedrooms is highly possible．Many people believe that robots will do most of our work, so we have more time for our hobbies.
There will probably be no school on Mars．Every student will have a computer at home which is connected to the internet．They can study, do their homework and take exams in online schools．Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today．Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today．Also, space travel will make many people feel ill．The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.

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 which uses satellites to find the user’s position．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.
