Good morning, I'm Kevin. This is my schoolbag. A photo of my family and some English books are in it. And a pencil box is in it, too. Is the pencil box purple? No, it's orange. It's my pencil box. A ruler, a pencil and a pen are in the pencil box. The ruler is mine. It is blue and red. The pencil is black and white. It is not my pencil. Look! That girl is I my friend Lucy. It is her pencil. That boy is my cousin, Tim. I find his green pen in my pencil box. His telephone number is 789 -5603. I lost my watch in the morning. I must find it.
