"I can't find Jack," Mary says. "Our pet is lost."

"We will find him." Paul says. Jack is a green lizard(蜥蜴). He can't go out of our classroom.

Paul helps Mary look for Jack. Jack isn't under the yellow desks or the blue chairs. Mary goes to the brown bookcase.

"Oh, a brown lizard is on the book." Mary says.

"The lizard is not green. It's not mine. It's a new lizard." Paul says.

Mary says, "Let's put it into Jack's box."

Paul puts the brown lizard into the box with some green leaves(树叶). Oh, what do they see now? They see a green lizard. The brown lizard turns into(变成) a green one.
