M: Hello, Lucy. This is Mac. How are you?
W: Fine, thank you. A bit too busy, though, you know, I’m trying to put everything in order in my new apartment.
M: Oh, I see. Well, (17) I was wondering if you’d like to go to a concert tomorrow evening. I think it’ll be good. And if I remember correctly, you did say you like pop music.
W: Yes, that’s right. I do. It’s nice of you to ask me, Mac. But I don’t think I can. (18) Margaret has already asked me to see a friend and then we’ll go to the cinema together. In fact, she’s getting the tickets this evening.
M: Oh, well. Never mind. What about next weekend? This concert is still on then, I think, if you’re free next Saturday.
W: Oh, I’d like to very much, but what time exactly?
M: Well, it starts at 7: 00 p. m. , I think.
W: Oh, good, that’ll be fine. (19) The basketball match will be over by 5: 30, I’m sure.
M: Good, I’ll call you again when I get the tickets.
W: Sure. Bye for now.
