听力原文:M: Excuse me madam. Would you mind letting me take a look in your bag? W: I beg your pardon? M: I'd like to look into your bag, if you don't mind. W: Who are you to insist? I advise you to take off, before I call a policeman. M: I am a policeman, madam. Here's my identity card. W: What? Oh... well... and just what right does that give you to go around looking into people's bugs? M: None whatsoever, unless I have reason to believe that there's something in the bags belonging to someone else. W: What do you mean belonging to someone else? M: Well, perhaps, things that haven't been paid for? W: Are you talking about stolen goods? M: Exactly, but if the citizens are honest they wouldn't mind, would they? W: Stopping people in the street and demanding to see what in their bags! M: I'm sorry. I'm trying to do my job as politely as possible. However, I must insist on Being what you have in you bag. W: And what, precisely, do you expect to find in there? M: Thank you madam. W: Net at all. M: Mm. Sixteen lipsticks? W: Yes, nothing unusual in that I like to change the eater with my mood. M: I see you smoke a lot. Fifteen cigarette lighters! W: Yes, I an rather a heavy smoker. M: Now are you going to come along quietly or am I going to have to call for help? W: But this is unfair! (20)
