The Life in the Future

　　What do you think the life in the future will be like?

　　Every family will have computers and robots. Computers will help us know a lot all over the world. Robots will help us do most of the housework. They can help us do some cleaning, cooking or washing. We can do some shopping and see a doctor without going out. Students can study at home on computers. People will live to be 200 years old because of the better medical care.

　　Our life will be better and better. For this, we should study hard. I believe we'll be able to do this.
