Do you mind being called a bad student？Of course not. So far as I know，everybody intends to be （become） a model student.
However，to be a model student is by no means an easy thing.

First，he must do his best to obtain knowledge. A man without sufficient knowledge will not succeed.

Secondly，he must remember to improve his health. Only a strong man can do great tasks. 

Thirdly，he should receive moral education. If his conduct is not good，no one will consider making friends with him.
