Mary is an American schoolgirl. She is now in Beijing with her parents. Mary doesn't know Chinese, but she is studying Chinese. She often speaks Chinese to her Chinese friends. Sometimes they don't understand her because she can't speak Chinese well.

    It's Sunday morning. She goes out. She is walking in the street. She is going to the zoo to see elephants and monkeys. But she doesn't know how to get there. She asks a Chinese boy. The boy can't understand her. Then she takes out a pen and a piece of paper. She draws an elephant on it, and shows the picture to the boy. The boy understands now, and he shows Mary the way to the zoo.
