Look! I'm Tom. This is a pencil box. It's yellow. It's my pencil box. What's in the pencil box? A ruler is in the pencil box. It is my ruler. The ruler is blue and red. That is a pencil. It is black and white. It is not my pencil. Look! That girl is Lucy. It is her pencil. That boy is Tim. I found his green pen in the Lost and Found Case(失物招领箱).I call Tim at 789-0003.It is his telephone number.
