    My ideal schoo lis not far from my home. It takes me 15 minutes to walk there. In the school, there are a lot of trees and flowers. It's very beautiful. We also have a big school library, a swimming pool and seven computer rooms. We begin our classes at 8:00 a.m. and finish them at 4:00 p.m. So we have a lot of time for after-school activities. Every day we only do our homework for an hour. Every month we can go on a school trip. How wonderful the school life is!
