Reading 2

This is my desk. On the desk, there are many things, my pencil, my pen, my ruler, my eraser, my exercise books, and my books. What's this, a red backpack? It is not my backpack, my backpack is blue . Judy, is this your backpack? Oh, it isn't your backpack? Then whose it is?Is it Lily's backpack?Her backpack is red. Maybe I should go and ask her.
