One possible version:
Computer Games and Our Health
Most boys in our class like playing computer games. Some of them even think computer games are part of their life. They play computer
games not only on weekends but also after school. It is bad for their health. Generally their eyesight is much worse than others. The air in the computer room is also not very clean and fresh. And they must feel tired if they play computer games for a long time. All those are harmful to their health. So please give up playing computer games. Try to spend more time on school work. Students can read books or play football instead. It is much more important for them to study hard and keep healthy.
