In brief, we can conclude that the one-child policy is inappropriate to modern China's situation, and it has already had many negative effects on the children's growth. So it's really the high time for us to take a second look at the policy.

In order to control the national population, the one-child policy has been carried out for a long time in Chia. It is undeniable that it has  achieved good effects. However, it brings some social problem. For example, it makes aging population more serious. In one word, like a double-edged sword, this policy has inevitably triggered several problems for children and parents, as well as the whole society. Therefore, I think it's time for China to cancel this policy gradually.

为了控制国家人口，中国长期实施了独生子女政策。不可否认，这一政策取得了很好的效果。但是，它也带来了一些社会问题。例如，人口老年化越来越严重。总之，就像一柄双刃剑一样，这一政策已经不可避免地给孩子，父母乃至整个社会引发了若干问题。因此，我认为中国是时候逐渐取消这一政策了。

Firstly, China's population has been controlled after years of implementation of the policy. And most people have realized the importance of birth control for a better life. On the control, the birth control policy make the proportion of aging people rise at an unstoppable rate. Therefore, it is time to cancel birth control policy to remit aging of population. Secondly, the one-child policy has revealed lots of disadvantages. Growing up with no brother or sister, the child feels lonely and isolated, not knowing how to communicate with others. Moreover, the only child in the familiy is likely to be spoiled by too much devoted love from their parents and grandparents. Therefore, they may be selfish, capricious and disobliging in their daily life.

首先，经过多年的政策的实施，中国的人口已经得到了控制。大部分的人已经意识到为了更好的生活而控制出生的重要性。控制出生政策使得老年化比例以不可阻挡的速度增长。因此，是时候取消控制出生政策以减轻人口老年化。其次，独生政策揭露了很多缺点。成长过程中没有兄弟姐妹的孩子容易感到孤独和孤立，不知道怎样与人沟通。再次，家庭中的独生子女很可能受到父母或者爷爷奶奶的溺爱。因此，在日常生活中他们可能是自私的，任性的，薄情的。

In brief, we can conclude that the one-child policy is inappropriate to modern China's situation, and it has already had many negative effects on the children's growth. So it's really the high time for us to take a second look at the policy.

简单来说，我们可以得出这样一个结论，即独生政策与中国国情是不相适应的，而且它已经对孩子的成长产生了许多负面影响。所以我们是时候重新审视这一政策了。
