题型:完形填空

With rapid increase of economic rate in western countries, more and more married young couples tend to have no child or only one. At the meantime, many developing nations adopt family planning policy to get rid of poverty. All these facts result in a world with population growth rate declining. But I myself would like to grow up in a big family.

Of course, a small family has its advantages. Firstly, small family makes it easier for parents to bring up and educate their children. Parents could spend more time and money educating one child than several. The child could grow up in an influential environment. Secondly, the child could learn more survival skills for future success.

However,                      . The only child becomes the little emperor. It would make the one child ask more for him and think less of others. Besides, after the child grows up and gets married, the new couple has to take care of four old parents. That means the two children must work hard to support the old parents. At present, many nations are facing the problem of becoming aged society. China will face this situation in a short time to come.

On the contrary, a big family weighs over a small family in many aspects. Firstly, parents could educate several children with almost the same time as they spend with one. Moreover, the old brothers or sisters also could help their parents bring up little children. Secondly, if one of the children turns out to be successful, it may mean he or she is becoming a model for other children to learn from.

Despite the fact that parents have to spend more time and money bringing up several children, it is not as difficult as people think it to be. With the help of good educational system and modern technology, it is becoming easier to afford several children.
