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 afterschool activities. For example, we can do reading for one and a half hour and play sports 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, or sat by the lake listening music. The teachers here are kind and helpfully. They are not only our teachers but also our friends.
