| The world is divided into two important parts. One half of the world is rich and the other half is poor. In the poor part, a lot of people never get enough to eat. In the rich part, a lot of people eat too much. In one part, children are hungry and in the other, a lot of people are fatter and fatter and have to go on diets or do some exercise to lose weight. For example, a dog or a cat in North America eats better than a child in the poorer countries. The poor countries have some difficult problems. Sometimes the land is too poor to grow anything on. The land can be got or made better, but a lot of things must be done first. The people must be taught and the water must be found. But rich countries have problems, too. They are not always pleasant places too live in. sometimes the air is too dirty to breathe and the rivers are too dirty to swim in or to take water. The roads and the streets are full of people and buses. Cars usually move very slowly. Noise is terrible. A lot of people do not have houses to live in. some things will have to be done about these problems. The air and the rivers must be cleaned, and more houses will have to be built. But these can't be done easily. 根据短文内容填写表格： Different lives in the world
