第30题: [多项选择]PART 3
·What is your opinion in one-child policy
参考答案:As China is having an enormous economic expansion it is also facing many problems. One of the major problems people have become more and more concerned about is the country’s population. It is also very well known all over the world that in China couples nowadays are not allowed to have more than one child. It has received lot of criticism from almost every corner of the world ever since. Many people, especially people in western countries, consider this policy as a strong violation of human rights. Even though I think this is a strong argument, I will, however, not concentrate on this aspect in this report, instead, I will try to give a brief analysis of the problems from a more demographic and economic point of view.
It is no doubt that a policy like one-child policy in China right now will bring many good effects. As each couple is only allowed to have one child, they will do the best they can to give their child good education and good living conditions. They will do a lot to make their own child to be the best. It is favorable for the child’s growth financially.
However, many people are worried about that today’s children are more spoiled than ever. That they are treated as small princes and princesses is not an exaggeration but rather a fact. Many of the children are self-centered and lack the ability to co-work with others even though they perform well individually. Children often have much pressure of being successful and do not allow themselves to fail. I believe that it is a problem can not be ignored because a well-functioning society is result of group work rather than a number of individual performances.
