Dear headmaster,

I’m writing to tell you some problems at the campus. It is common that students are accustomed to have snacks and drinks after having sports.

I’m worried that if students addicted to snacks and drinks, it will do great harm for their health. They need to take in all kind of nutrition. Therefore, snacks and drinks can’t meet his needs to grow up normally. On the other hand, it is easy that for students to get into the bad habit of spending money in buying such kind of things, which is the waste of money.

In my opinion, students should have regularly meals. Meanwhile, we can eat fruits or drink milk to make sure that we can develop healthily.
