ince the 1970’s the Chinese government adopted a policy of family planning---- single-child policy---- as a basic state policy to solve this problem. Until now, this birth control policy is still implanted in our country and both positive and negative effects have been harvested.
With the adoption of the family planning policy, the rate of population growth has been successfully controlled. This has already brought about some satisfactory results in China. For one thing, people’s living standard has been greatly improved with our country becoming more and more prosperous, and our national economy developed steadily. Furthermore, with decreasing population, the problem of shortage of water in parts of China is solved gradually. In addition, with the low rate of birth, it goes with less energy consumption, which will benefit the overall development of our economy. Moreover, this policy has greatly reduced the financial burdens of the parents who have otherwise had more children, enabling them to focus their resources on the single child’s well-being and education.
However, the implementing of this policy also brings about some problems. First of all, as there is only one child in a family, the child becomes “little emperor” or “little empress” of the family, surrounded by parents and grandparents. The spoiled child can get whatever he likes and discards whatever he dislikes. This phenomenon is more popular in large cities will do great harm to the children themselves. They don’t cherish what they have got because they can easily get whatever they would like to. Worse still, in the future when they grow up, they might feel very difficult to adjust to the society or cope with the adversity. Some people also show great concern that when the single children get married, the couple have to take care of 4 old people.
While admitting that single-child policy does bring some negative effects on the single child, we must take it for granted that it has benefited and will continue to benefit the country. Therefore, we should carry it one and at the same time adopt some measures to avoid the adverse consequences the policy may produce.

今天，我们学校举行了唱红歌比赛。下午第二节下课，我们都排好队，等待着校长安排。一会儿，我们都从班里拿出凳子，在操场上排了一个大大的方阵，台下许多同学都坐了下来。一会儿，每班都选一个代表去捏纸蛋来排顺序，我们班第四。可同学们还是说：“要是第七多好啊！”“不对，应该是第六，六六大顺嘛！”“不赖了，第四知足吧！”又过了一会儿，还不到一节课，就都唱完了。中间轮到我们时，我十分紧张，心里像揣了一只小兔子一样，“嘭嘭”的直跳，开始唱时，也就没那么紧张了。我们很顺利的唱完了两首歌，而且每一个动作，每一首歌，我都觉得非常完美了。可是得出来的分却不尽人意，9点31分，我们老师并没有参加。所以我们非常遗憾得了最后一名，其他班只是老师参加了而已，所以都加了一分。并不是靠他们自己的实力的来的，并不光荣。
在比赛结束后，老师语重心长的说：“这次失败并不遗憾，我不会指挥，也不会唱歌，是我让大家与奖状擦肩而过，我向大家道歉。”说完深深的鞠了一躬，又眼含热泪地说：“我们以后一定会拿到一个好名次，这次并没有失败，只是成功的起点……”大家都沉默了起来。
我想：这次失败并不怎么可怕，可怕的是我们不团结。只要我们团结，团结就像一把利剑，披荆斩棘，斩断所有的困难。
愿这次失败让大家永远铭记在心里。
