    In China, two-child policy(政策) has come out. That's to say, China now allows two children for each family. However, different people have different opinions about it. Some parents are willing to have a second child as soon as possible. They think the second baby is a gift for themselves. One child will feel lonely when his parents go out for work. Two kids will help each other and share happiness and sadness together. In Chinese tradition, the old people wouldn't like to spend their later life in the old people's home. After the second baby grows up, he will be able to share the pressure of looking after his old parents. China has become a country with an increasing number of old people. Two-child policy will improve the balanced (平衡的) development of population. However, other parents refuse the second child because they have some worries. For example, they can't afford the cost of education. They also worry that their two children won't get along with one another. Maybe the young people can't find jobs easily in the future. For our country, perhaps the policy will lead to the house and population problems.

    In a word, more and more families will have a second child. Do you mind having a brother or a sister?
