What will our life be like on Mars in the future?With the rapid development of hi-tech,the Mars will change a lot in many ways in the future.We'll completely live in the cyberspace.First,we find the Mars haven't been polluted.Air and water becomes more tidy and fresh thanour earth.Second,if we want,we can study in the sapceship.And people don't need to go to thefactory to work,instead of working by computer at home.On the other hand,it is very easy for usto visit the Earth and other stars by riding spaceship.I hope all this can come true.But first,we must treasure and protect Mars and avoid it becominganother polluted earth.If all of us try our best to do it,we will enjoy our life.
