I think life in the 25th century will be more comfortable and convenient. Many things we are dreaming of will come true.First of all，there will be no longer any war. The world becomes peaceful. It's easy for everyone to go around the world.
As a student，we shall learn more widely than today. And learning will become much easier with the help of computers. We can go to the Mars for holidays. Let's do our best to make our earth a more pleasant place to live and work.
