参考范文
Dear classmates，
It is known to us that nothing is more important than heath. However，there are some unhealthy behaviours in our daily lives. For example，some students don't have breakfast before going to school. Others may stay up late to play computer games. And even some students like to eat junk food，like hamburgers and fried chicken.
What should we do to improve our health? The following are my suggestions. First of all，we ought to get up early and go to bed early，so that we can have a good living habit. Second，we need to have a balanced diet and do some exercise，which can build our bodies up. Third，we had better not spend too much time on computers or phones，because it may be bad for our eyes.
All in all，a healthy lifestyle makes a difference. Each of us should take action to change the incorrect behaviours right now.
That's all. Thank you!
