听力原文：George: Hi, Susan, I was wondering if you're free tonight. Susan: Well, George, I need to see my professor at four, and then I'm going to the supermarket, but I guess yes, I am. Why do you ask? George: I have just received two tickets for Harry Porter from a friend of mine and was thinking of inviting you to go with me. Are you interested? Susan: Yeah, definitely ! Thanks for inviting me! George: No problem. Susan: I really wanted to watch Harry Porter on the opening day but the pre-sale tickets were sold out. How did you manage to get hold of them? George: A friend of mine works at the cinema. He was able to get the tickets for free, and then he sold two to me for ＄ 30 each. Susan: You paid ＄ 60 for the tickets that he got for free? That's really expensive! George: Well, I guess it's worthwhile considering the fact that other people are paying as high as ＄ 60 each on the 'black market'. Besides, I knew you were really looking forward to watching Harry Porter on the opening day. Susan: Wow, I'm really honored you went through all this trouble just for my sake. I really appreciate that. So, what time are we going? George: Well, let's see. The movie starts at 10 pm. We should get there at least 1 hour earlier because there'll be a big line. I could pick you up at your house at 8, if that's OK with you. Susan: Eight o'clock? That's fine with me. George: Okay good. See you then. Susan: See you. (23)
