听力原文：M: Hey, honey, why do you look so happy? W: Great news. We just won $400 in the lottery. M: Wonderful! How do we spend the money? W: Well, I'm just thinking about it. Can we buy a new microwave stove? M: With $400, we can afford the most expensive one. W: Sure, but on second thought, don't you think our washing machine is out of style? M: Well, that's still affordable. Hey, how about a camera? Look, we don't have a camera; a camera will give us a lot of pleasure. Why should we spend all our money on family appliance instead of some luxuries? W: Well, I don't think it's a good idea. M: Ok, let's think carefully about it. W: Oh, How about something more exciting and attractive. M: What is it? W: Why not buy some jewelry? I need something that makes me more elegant and beautiful. M: Well, in my opinion, you are pretty in your plain way. W: Really, thank you, but I still insist on having a gold necklace. (20)
