阅读下列短文,根据短文中的信息完成文后表格。(每空一词)
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, many 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. 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 get better, but people have to do a lot of things first. They should learn how to enrich their land and how to find water.
But rich countries have problems, too. 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. People must do something about these problems. We should do something to make the air and the rivers clean and build more houses. But it will take a long time.
