    阅读下列短文,根据短文内容从每题所给的A、B、C、D四个选项中选出最佳答案。(每小题2分)
    It’s said that a thousand years ago there were less than 400 million people on earth. Today, however, the world’s population has come  to 5,000 million. What is worse, it keeps growing at a surprising speed. If this continues, the world’s population will shoot up to 8,000 million by the year 2025. This is what we call population explosion (人口爆炸).
    With more and more people coming into this world, human beings are now  being short of food. What’s more, farming land is becoming less, so country people are moving to the towns and cities in the hope of finding a better life. But the cities couldn’t  provide enough housing, and the newcomers live in crowded rooms. Finally, too few jobs causes unemployment(失业) ,then makes people poorer, especially in poor countries. They have to run faster and faster in their economic(经济的) activity in order to stay in the same place, so the rich becomes much richer and the poor becomes  poorer in the poor counties every year.
