听力原文:W: Hello, Patrick, is that you? M: Yeah Jane, what can I do for you? W: I was calling about the apple tree that you were trimming yesterday. M: That was hard work! W: I'm sure it was. It sure looked difficult. M: Yeah, I'm glad it's finished. Hauling the branches to the front for garbage pick up was no fun either. W: Well, I don't think you're quite finished yet. Some of the larger branches fell over into my yard, and I think you should come and get them. M: Listen Jane, I don't see why I should do that. You eat all the apples that fall in your yard and you've never complained about that before. W: Well, it's easier to pick up apples then to drag tree branches all the way to the curb. My kids pick up the apples, and the branches are just too big for them to drag. M: Well, I guess you'll just have to do it yourself, Jane. W: Patrick, I wish you would reconsider. We've always gotten along fairly well, but I think you're out of line here. The branches are your responsibility. M: Sorry Jane, I disagree! You take the benefits of the apple tree, but refuse to deal with the bad side of it! Besides, it won't take you any time to get the branches out front! W: Get the branches off my property or I'll have to sue you. M: yeah? For what?! You're taking those law classes too seriously! I've got to go. I have to pick up my son. W: You'll be heating from me. M: Yeah, yeah. See you in court Jane. (23)
