In 100 years, the world will be better than now. Science and technology will make bad things disappear (消失). Machines will do the dull jobs and make delicious food for us. Robots will clean houses and wash clothes. So we will have more free time. We can see films, visit our friends, play interesting games and travel around the world. The weather will always be warm. And there will be many trees in the world, so deserts will disappear. Our homes will be more comfortable and our life will be more interesting.
