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.
