Question 12 is based on the conversation you have just heard.

听力原文

M: Well, I think that was quite a successful trip in the end. Don’t you think, Jenny?

W: Absolutely. (12) [There are lots of great potential markets here in China. So I’m sure that the head office in London will be pleased once we get back and present our research.] 

M: OK, we’ve got a bit of spare time now. Can we discuss the return trip to the head office？

W: Sure, I’ve checked the availability of flights from Beijing to London on the 22nd. And you have a choice. There’s a flight arriving the following morning with a two-hour stopover in Dubai, or a flight arriving at 11:30 in the evening with a five-hour stopover in Amsterdam.

M: Right. (13) [Well, that’s obvious then, isn’t it?]

W: (13) [OK. So that’s Dubai.] I’ve booked a room in a hotel about a mile from the office. The nearest metro station is Earl’s Court.

M: Great. (14) [Can you find a map that shows where the hotel is and send it to me online?] I’ve never been to the head office, you know. I want to see if I can get one of those rental bicycles and ride to the office just for fun. For the presentation, I’ll bring my own laptop and hook it up to their projector. Do you remember the capacity of their meeting room？ 

W: No, but I’ll check.

M: Just one more thing. I’ll pay everything with my own card, right? And I’ll submit my claims form afterwards. 

W: No problem. (15) [Just remember to keep all your receipts.] You remember the trouble you had last time?

M: Oh, don’t remind me.

12. Why are the speakers in China?（讲话者为什么去中国？）

解析：B。录音开头女士说到，中国有很多巨大的潜在市场，并确信等他们回去介绍他们的研究（research），伦敦总部那边会很满意。由此可知，讲话者去中国是为了研究中国的潜在市场，B项符合题意，故为正确答案。

错项排除：A项的sign a business contract和C项的make investments在录音中无依据，故均可排除。D项利用office设置干扰，但录音中说的是伦敦总部，而不是要在中国开设办公室，故排除D项。
