Good morning, everyone. My name is Minh Anh. This is my school. It is small and old but it is beautiful. Behind the school, there is a large yard. We often play soccer together here. The yard is clean and there are many trees and flowers there. My friends and I sit under the trees every morning to review our lessons. My school has two floors and fifteen classrooms. My classroom is on the first floor. There are forty-three teachers in my school. They are good teachers. I love them and I love my school very much.
