My name is Mary. I am a schoolgirl and my school is very big. There is a large playground in my school. After class, you can see many students playing on the playground. Look! A boy is skipping rope. But it is not easy for him. Oh, he falls down. His friends come here and help him. One of his friend teaches him to skip rope. Look! His friend can skip rope very well. He skips faster and faster.
They are laughing happily (开心地大笑).
