听力原文：W: Good morning, Mr. Tim. It's a long time since I had the pleasure of a visit from you. M: Yes, it must be three or four years. I haven't visited you since I called about my will. You helped me with that, you remember? W: Yes, I remember. Do you want to make any changes in your will? M: I don't think that will be necessary, but you'll tell me if it is. I left everything, you remember, to my wife, and after her death, to my son Jerry. I've about $ 15, 000 in shares of industrial companies. These bring in, after paying tax, about $ 1, 125 a year. Well, I'm earning a good salary now, and I shall get a good pension from my employers, so my wife and I can live fairly comfortably with this extra income. I want to buy some land and build a house for my son he will need a house when he gets married. I'm thinking of building one and giving it to him. W: Your son's lucky. So you want my help buying the land and building the house. M: Yes, that's right. As soon as you've done what's necessary for buying the land, Jerry and I will see an architect. W: Have you found a plot yet? M: Jerry was in Edinburgh last Saturday and saw a plot he likes. My wife and I went there two days ago, and we liked it, too. I'd like you to make the necessary inquiries for me. W: I'd be pleased to do that. I shall have to write to the Local Authority and inquire whether it is allowed to build a house on your piece of land. You're not allowed to build a house without permission from the Planning Authority. And sometimes the Authority decides that a house must be built of stone, and not of brick, so that it doesn't spoil the surrounding village. How long have they not met each other?
