《新概念英语》第一册第129课 Seventy miles an hour
ANN: Look, Gary! That policeman's waving to you. He wants you to stop.
POLICEMAN: Where do you think you are? On a race track? You must have been driving at seventy miles an hour.
GARY: I can't have been.
POLICEMAN: I was doing eighty when I overtook you.
POLICEMAN: Didn't you see the speed limit?
GARY: I'm afraid I didn't, officer. I must have been dreaming.
ANN: He wasn't dreaming, officer. I was telling him to drive slowly.
GARY: That's why I didn't see the sign.
POLICEMAN: Let me see your driving licence.
POLICEMAN: I won't charge you this time.But you'd better not do it again!
GARY: Thank you. I'll certainly be more careful.
ANN: I told you to drive slowly, Gary.
GARY: You always tell me to drive slowly, darling.
ANN: Well, next time you'd better take my advice!
