A、A tie. B、A pet frog. C、A leather bag. D、A pipe. C对话中，女士先后否决了男士送领带、宠物青蛙的建议，男士随后又提议送一个上等的皮包，女士认为是个好主意。故本题答案为C。

W: What should I get Uncle Teddy?
M: You could get him a tie.
W: Are you kidding? (19)That’s the stupidest Christmas gift one can buy. I don’t want to get a tie. (20)Everybody gets men ties for Christmas. It’s too boring. I want a more unique gift.
M: Well, you can buy him a pet frog then.
W: That’s a cool idea. At least it would be a surprise. But I’m afraid he wouldn’t take care of it.
M: How much do you want to spend?
W: Well, he was very good to me. He helped me edit my essay for the scholarship contest. So I want to spend at least 75 dollars.
M: Alright, I have an idea. You know he carries that conservative-looking briefcase every day. (21)I think he would appreciate having a very fine leather bag. You know, not so hard and square like a briefcase.
W: (21)I think that’s a great idea. Men look great with that kind of bag. Where can we buy one?
M: I don’t think this mall has a leather goods store. So we have to go to State Street.
W: Alright. We can go later then.
M: We can buy something for Mom and Dad here, and then go buy Uncle Teddy’s gift on State Street.
W: Good plan. What should we get for Mom though?
M: She said she wants one of those automatic foot massagers. I think they sell them at Sears.
W: Alright. And what about Dad?
M: How about a pipe? He would sure love it.
W: Wonderful! Since we’ve decided what to buy, let’s get started!
