One possible version:

     Nowadays, many school children are addicted to computer games. Every day after school, they go to

the Internet bar to play computer games until late at night without letting their parents and teachers know,

and they often have a competition to see who wins more scores in each game.

     Let me take Tom for example. Tom used to like computer games very much and spent a lot of time on

them. However, an incident changed him completely. Once Tom didn't go home until eleven o'clock at night.

When he got home, he told his mother that he had been reviewing his lessons. Poor mom! She believed him

and cooked two eggs for him. "Take more care of yourself as you work too hard, my dear son." She said

to Tom. But Tom's face turned red at his mother's praise. He realized that he was wrong, and he made up

his mind to study hard at his lessons. Later, he did become a good student and was often praised by his

teachers and parents.

     As the saying goes, "It is better late than never." All the students should concentrate on studies instead

of computer games.
