Mary is an American school girl. She is in Beijing with her parents now. Mary doesn't know Chinese and she can't speak Chinese well. It's Sunday morning. She goes out. She is walking on 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, and he shows Mary the wav to the zoo.
