【正确答案】It is good for the whole world to see that China is developing rapidly in spite of the many problems which hinder her development. Admittedly some problems are very serious, such as over-population, limited natural resources, and the lack of arable land. However, it is said that over-population is the most urgent problem, and I have my doubts about this. First, in my opinion, over-population is a problem met by many countries, both developing and developed countries. Many have a denser population than China. For example, the UK is two and a half times as densely populated as China. But the UK is richer than China. In fact over-population in China often appears in large cities such as Shanghai and Beijing, while there are large areas of land that are inhabited. So the problem is not so much the density of the population as the distribution. Secondly, we must not lose sight of the fact that after about 20 years' efforts to control the birth rate, China's population is almost stable. Most people are willing to adopt family planning. This will be good for stabilizing the population of China. Furthermore, there may certainly be limited natural resources, but if we use them reasonably, and distribute them fairly, we may still have the wherewithal for development. Finally, in my opinion, too many people is not a problem in itself. The problem is how to educate people. If our people are full of knowledge, the development will come about more rapidly. So China's urgent problem is not over-population, but how best to educate people, and how to make best use of the natural resources.
