　A good middle student, I think, should be diligent in his studies. The more he studies, the more he will increase his knowledge. Without enough knowledge, we cannot make great contributions to the modernization of our country.

　　To take care of one's own body is another important thing for good student to do. Anyone, who hasn't got a strong body, can do nothing for his country, even if he has much knowledge. There was a man, who, when he was student, studied hard but neglected his health. No sooner did he come to serve the country than he died of poor health.
