Dear Dairy,
Today is our Open Day. Our parents come and visit our school on this day.
Our school looks nice and big. The playground is very big and our classrooms are clean and bright. We also have an art room, a music room, a biology room and a small hall.
The Open Day starts at 9 a.m. in the playground. Everyone watches the students play different sports. Next we go to the art room to enjoy all the students’ pictures at 10 a.m. At 11 o’clock we all go to the school hall for a short meeting, and then we have lunch. After lunch, we have a little rest for half an hour in the hall. At 2p.m.we have a look at all the students’ work in the biology classroom. Finally we go to the music room and listen to some students play music at 4p.m.
Everyone has a good time at school on this day.
