About the future,I have some predictions.In fifty years,I will be an old man .There will be some robots in my home .They will serve for me .There will be more and more trees around the world.We'll have fresh air easier.Kids won't have a schoolbag with a lot of books.They'll take only a iPad to school to study.If we want to buy something,we will not open our wallet and use money to pay for it.Because everything will be free in fifty years.There will be fewer cars on the road.People will use subways,bikes or buses more.
All in all ,if people will try to improve our lives ,these predictions will come true one day.
