Cindy is a student and her sister is Helen. They are 12 years old. They live in a big room. Now let's look at their room.
Their books and keys are in their brown bookcase. They have a white clock. It's on the yellow desk. Their computers are on the desk, too.
Helen's things are everywhere. Her pencil box is on the sofa. Her ruler is on the chair. Her schoolbag is on the bed. Helen is not tidy. She often asks Cindy, "Where is my schoolbag?" "Where is my pen?"
Cindy likes green. She has three green baseballs. They are all in a box. The box is under the desk. Cindy is tidy.
