This is a classroom. in the classroom you can see a teacher's desk, a blackboard and desks. there are three windows and one door in the classroom. there is a map on a wall. that is the my desk. it is in comer of room. there is an exercise-book on my desk. I have an English textbook. A textbook is in the my bag. you can't see a bag. it is in a desk.
