英语作文should middle school students have birthdaieparty?

In China, the communicative competences of the middle-school (or high school) students are greater and greater. Some students started to make birthday party. Because some student think birthday party can help the students improve the communicative ability and friendship, but have some problems. So,I think we shouldn't hold birthday parties.Here are my reasons.
First, this birthday party for students is a waste of parents' money. Some student s may buy some expensive presents for friend who have a birthday party. We are incapable of earning money, so we spend our parents' wages on the present. Second, this is a waste of time. It costs not only so much time and energy to hold a party, but also influnce our study. Third, this is easy to get into bad habits of smoking and drinking.
The above is my reason.All in all, we shouldn't hold birthday parties.It can let we don't like study.Let we don't waste time!Let we study hard!
