We have English lessons at Room 12. There are 24 tables for students and one desk for the teacher. On the walls, there are a lots of posters of England. There’s a cupboard at the front of the room and on the cupboard, there is a TV and DVD player. Sometimes we watch films. There are some bookshelves in the classroom. On the shelves, there are a lot of English books. Our books are on the teacher’s desk. He wants to look at our homework. Our school bags are on the floor, and there is some food in the school bags. It’s now 5.30 pm. We are at home, but our teacher is at school. He often stays late to prepare for tomorrow’s lessons.
