【答案解析】[听力原文]
   W: Hello, Happy Time Catering Services. Victoria speaking. How can I help you?
   M: Hello, Victoria, this is Joe Smith from Country Holidays. I wondered if you could do some catering for us next week. We are having a small reception. It's to launch our summer holiday advertising campaign. Would you be free?
   W: When exactly is it, Mr. Smith?
   M: April 21, that's Thursday. Oh, sorry, no, it should be Friday.
   W: Oh, yes, I can do that. Where will you be holding it?
   M: We thought we'd have it at head office and use the conference room because there is enough room for everyone there.
   W: OK what sort of things would you like?
   M: Just a light lunch, I think. So that people can eat while they move around and talk to each other. You did something similar for us last year. We'd be happy to have the same menu again.
   W: Right. I will look at my diary and see what you had last time. Oh, I nearly forgot to ask you. How many should I cater for?
   M: Well, I think most people will be able to come. Perhaps around 30. No, let's say 35 to be sure.
   W: Right. Thank you for getting in touch, Mr. Smith. I'll send you confirmation of the arrangements by the end of this week.
   M: OK.
   What did Joe Smith telephone Victoria for?
由对话可知，Joe打电话给Victoria是想让Victoria所在公司为他们的招待会提供餐点服务，因此选C。A、B分别是招待会的菜谱和地点，为具体事宜。D是公司广告活动，不是Joe打电话给Victoria所商谈的内容。
