It is important for us to know how to be a good student. A good 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. From this we may see that to have a strong body is really very important for a student. Lastly, to cultivate one's own virtue is most important. Virtue is the essence of a noble and good character. It will greatly help one to be useful and his country heart and soul. When learned people go astray, they do more harm than good to society. We should draw lessons from this.
