Hello! My name is Eric Miller. I’m a geography teacher. But now I teach English in a middle school in Beijing. I’m in the classroom now. I can see some things in the classroom. What are they?

There is a notebook on this desk. It’s Jack’s notebook. I see his name on it. A Chinese-English dictionary is on that desk. It’s red. Whose（谁的） dictionary is it? I don’t know. Thirty students have red Chinese-English dictionaries in my class. What are those under that chair? They are three pencils and they are Mary’s. Is the short yellow ruler Mary’s, too? No, it isn’t. Mary only has a long ruler. It’s Helen’s. She has a short ruler and yellow is her favorite color. I can see a white model plane over there, too. Whose is it? I think it’s Peter’s. But where is Peter? Oh, he is in the school library.
