Sam is asking a policeman.
Sam: Excuse me. Where is the art museum?
Policeman: It's near the post office on Main Street.
Sam: Is it far?
Policeman: No.
Sam: How can I get there?
Policeman: Go straight and turn left at the bookstore. Then turn right at the cinema and you can see the art museum.
Sam: Thanks!
Policeman: You're welcome.
Zhang: Excuse me, how do we get to the People's Park?
Man: You can go there by the No. 5 bus, or you can go on foot.
Zhang: How do we go on foot?
Man: It's easy. Turn left at the traffic lights. The park is near a tall office building.
John: Thank you very much. Hurry up, Zhang Peng!
Zhang: No! The light is red. Stop!
John: That's right. We have to wait.
Zhang: Now it's green. Let's go!
