People have few places to live in. But luckily, China has known the serious problem. So China has come up with some ways to control the population.(教师停顿解释，引出本课短语，让同学感知。)“Come up with some ways” means “do something”， so this sentence can be changed into:“China has done something to control the population.”(教师继续朗读学生作文。)One-child policy makes the population slow down. Chinas economy grows faster and peoples living conditions are improving rapidly. Most of the families can give their children a chance to have a good education.(教师讲解，引出新词。)“give their children a chance to have a good education” we can also say:“offer their children a good education.”(板书)offer“offer” means “give sb.sth.” or “give sth.to sb.”.(教师继续朗读作文。)But the population problem is still serious in China.(教师点评:并提出几个简单问题，引导同学回答。)T: I think its a wonderful article.
