T: To my surprise, you have known about the population so much. Quite good. Now, turn to Page 14 and discuss the questions of 3.

(学生们互相交流想法。)

T: OK. Let’s write an article about the population problem in China to your pen friend in another country. The questions that you discussed just now may help you. Pay attention to the form of the letter and try to use the present perfect tense in your article. You can write now.

(学生准备过程中，教师深入指导。)

(程度好的同学快速完成，教师让其读范文。程度差的同学注意听，课后继续完成。)

T: Who can read your article to us?

For example:

Dear...,

How time flies! I have been back to school for two weeks. These days, I have known a lot about the population in China.

China has a population of 1.3 billion. It has reached about one fifth of the world’s population. About 80 percent of the people live in the countryside. It causes many difficulties. In less developed areas, some parents prefer boys to girls. Not all the families can offer their children a good education. Some children can’t go to school.

China has taken measures to control the population. China’s economy grows much faster and their living conditions have changed a lot. Most of us have lived in bright and tall buildings. We have had ring roads and they are wide enough. We have had more comfortable life. However, the large population problem is still serious in China.

How about the population of your country? Can you tell me about it?

Yours,

Kangkang

T: You have done well. Next, who is ready to read yours?
