话题：请围绕独生子女，阐述观点。
参考例文一：
China has the largest population all over the world which makes it difficult to develop economy well. Thinking about China's economy development some hold the view that it is necessary for China to implement one child policy. While others think that one child policy does no good to children's growing up. I am in favor of the latter opinion.
Firstly one child policy will make children feel lonely. It means every couple only has one child. We know clearly that there is not everything children are willing to tell their parents. Growing up with no brother or sister, the child may be easily in mental problem such as autism. In addition, parents with only one child will spoil their child overly. As a consequence the child will be the so called little emperor or little princess. When the child grows up it is difficult for the child to adapt to the world the society
All in all to some extent one child policy will solve the large population problem but from the perspective of long term development of china it does no good. Because we must take the young generation's healthy growing up into consideration.
参考例文二：
It is indeed the most effective way for China with implementing family planning to solve the population problem. But family planning has so far made little progress. While half of the world is suffering from starvation, poor health and a low life standard, we cannot just think lightly the population problem. We have to make the birth rate under control.
The main enemy of family planning is illiteracy. For example, Brazil and India have the highest birth rate, and they embrace the highest illiteracy rate, and their people even have no idea of birth control.
Nowadays China's population is growing rapidly. Therefore it is crucial for China's economic improvement to control the growth of population. China should spirit up the whole nation to take actions.
