　　Some people are pessimistic (悲观的) when they thint the future. They say that, a hundred years from now, we will have used up most of the earth’s resources. We will have made our seas so dirty that we will not be able to eat fish from them. There will be so many people in the world that we will have to use all the countryside for housing; there will be no farmland left.
　　Other people have a different idea about the future. In their view, the city of the future will be a huge pyramid-shaped (金字塔形的) building, which will be floating on the surface of the sea. About 5,000 families will live there, and there will also be schools, shops in it.
