     Look at this classroom. What is in it? There is (有) a schoolbag. Is this schoolbag Tim's? No，it isn't. It's      ， but Tim doesn't like brown. It's on Jack's desk. Maybe(也许) it's his. Is this yellow ruler Kate's? Yes, it is. She likes rulers very much. What's this? Oh, it's an English dictionary. Whose (谁的) dictionary is it? Let me see. Tina's name is on the dictionary, so the dictionary must (一定) be hers. Look at those pencils. They are white, green and purple. They are on George's desk. Here is a black pen. It's on the teacher's desk. It must be Mr Green's. Look at these English books; they are mine. I like English.
