通过检查学生的家庭作业来复习有关的人口问题，并对学生习作进行总结和拓展，导入新课。
1. (教师在实物投影仪上展示Section C中3的学生习作，复习上节课内容。)
China has the largest population in the world. There are about 900 million people living in the countryside. The large population causes many problems today.
For example, we are short of energy and water. Most of the cities are more crowded than before, and the traffic is much heavier. The large population has become a serious problem. Some parents in less developed areas prefer boys to girls. So they don’t offer girls a good education. In order to give people comfortable lives, China’s government has taken some measures to control the population. One is known as the one-child policy. Thanks to the policy, China is developing quickly, and people’s living conditions are improving rapidly. Our lives are becoming more and more comfortable.
