听力原文：Lin: Excuse me. May I look at that blouse? Salesman: Certainly! Lin: (Examining it) Mmm! Salesman: I can see that you have very good taste, ma'am! It really suits you! Lin: Yes, but it's not for me. It's for a friend. She asked me to buy one for her. What are you asking for this? Salesman: Well, madam, you're very lucky because we have a special offer on, for this week only! So that blouse is normally $60.00, but we are offering a 10% discount. Lin: Oh dear! That's still more than $50.00, and she asked me to spend only 40. Salesman: I see. Well, ma'am, but just look at the quality of the silk! Lin: It's very nice, but I think your prices generally seem very high. I can get a blouse like this at half the price through the Internet! Salesman: But not of this quality, madam! Lin: I tell you what, I'm in a bit of a hurry, so why don't we split the difference? You're asking for $54.00, and my friend's price is 40. Let's settle on 47! Salesman: 47? At that price I'm losing money! Look, I like you. I'd like to help you. So let's call it 50! Lin: 50? Well...Oh look. There's a button missing! Salesman (Checking) Are you sure? Okay! Let's make it 48! (20)
