Today is sunny. Peter, Alice and l are in the park. The park is clean (干净的) and big. We see some kites in the sky. There are three green kites, five blue kites and four red kites. Peter has a pizza in his hand. It's round. Alice has a camera(照相机). It's small and grey. Alice likes it very much. I am hungry and thirsty. I have a cake and some milk. We are happy.
