Example 3：l agree on the One Child Policy in China. There are three reasons.

First, China has the largest population in the world. The population of China is 1.3 billion now. The large population has made many bad results, such as environmental problems, traffic jams and so on. So to reduce the population is urgent. In China, we should obey the One Child Policy so that we can control the growth of the population.

Second, the One Child Policy has made a contribution to improving the people's quality. In a family of three—father, mother and the child, the child is usually brought up patiently, and the parents let him or her receive good education and want him or her to be a useful person to the society. Then, the child will have the best body and healthy mood. This can contribute to his or her success in the future.

Third, when the only one child in each family grows up, as the child has no brothers or sisters to talk with at home, he or she must be trained to get on well with（与相处得好）other people, such as his classmates, teachers and other family members. He has to get used to（习惯于）communicating with others. He will have a good social relationship.

Nowadays, it’s difficult to find a job, and the natural resources are reducing. If there are fewer people, more energy will be saved. China is still a developing country now, and most of the developed countries have a small population. I'm sure the One Child Policy will bring many advantages to China.
