Millions of years ago, the dinosaurs(恐龙) ruled the earth. Since then, there have been no dinosaurs. What happened to then? We know they did not all die at once. It may have taken a few million years for all of them to die. In the days of the dinosaurs, the whole earth was warm and wet. There were many green jungles(丛林). But the earth changes slowly, all the time. When parts of the earth became cold and dry, the jungles there died. Then dinosaurs could not find enough to eat. This must be on reason why the dinosaurs died out.
