Last week we held a heating discussion on which we should do for our school before we graduate. The students in our class have different suggestion. Some students thought that we can collect money to buy some books for the school library or everything else for the schoo1. Others students think that it’s not necessary to spend money. We can study hard and make our school satisfied with us.
In my opinion, we don’t have to spend money. We can do something meaningfully without money.  For an example, we can do some voluntary work to beautify the school and try to get better results in the coming exams so that our school will proud of us.
