Hi, my name is Peter. This is my schoolbag. It's blue. I like it very much. There are four books and a pencil-box in it. And an English dictionary is in it, too. That is Helen's schoolbag. It's yellow because her favorite color is yellow. Her five books and a red pencil-box are in her schoolbag. There is also her ID card and her keys.
