My dream school starts at 8:30 a. m and ends at 3:30 p. m. They are three lessons in the morning and two in the afternoon. We didn’t need to do so many homework. Therefore , we have more time with after-school activities. For example, we can do reading for one and a half hour and take exercise for one hour every day.
My dream school look like a big garden. There are all kinds of the flowers and trees around the Classroom buildings. We can lie on the grass for a rest, sit by the lake and listening music. The teachers here are kind and helpfully. They are not only our teachers but also our friends.
