School is over. Jim and Ann are in the classroom.
Jim: Ann, let’s clean the classroom.
Ann: OK. Let me clean the floor.
Jim: Let me clean the desks, the chairs and the blackboard.
Ann: Look, Jim! There’s a schoolbag under the teacher’s desk.
Jim: Really? What colour is it?
Ann: It’s black and blue. Oh, it’s so heavy! Let me put it on the teacher’s desk.
Jim: What’s in it?
Ann: Let’s open it and see. Look! A pencil box, two Chinese books, a maths book, an English book, three storybooks, a key and a blue toy car.
Jim: Ken has a blue toy car. Maybe it is Ken’s schoolbag.
(Ken comes in.)
Ken: Excuse me. I lost my schoolbag. Is it in the classroom?
Ann: Look! Is this your schoolbag?
Ken: Oh, yes! Thank you very much. Let me help you clean the classroom.
Jim/Ann: Great!
