Now you'll hear the two long conversations.
Conversation One
W: Sit down, please, Mr. Black. I hope you enjoyed your journey.
M: Of course, I did. It was a wonderful trip.
W: And I suspect this morning we'd like to get down to business. How would you like to proceed with the negotiations?
M: I'm here at your disposal.
W: Let's draw up an agenda for our discussion, shall we?
M: Fine. One of the items for our agenda would be the supply of computers to China in the second half of this year. [19/[20]]As you know, our current contract is about to expire, and we will need to discuss a new one.
W: Certainly, we are ready to hear your proposals.
M: Something else I'd like to discuss is the possibility of establishing a long-term agreement between my corporation and yours.
W: Yes. So long as it's in the interest of both sides, let's talk about it. Is there anything else you'd like to achieve on this visit?
M: Yes. [20]I'd like to build on the fact that we have had a very cooperative relationship in the past few years. Your government now has a policy of opening up to the outside world. My ambition is to promote trade between our two corporations. It is said a new policy is being put into practice in your foreign trade. Is that true?
W: Yes, but we still stick to a consistent policy in our foreign trade. [21]We insist on the principle of equality and mutual benefit, as well as exchanging needed goods.
M: Would you give us a brief account of the new practices you have adopted?
W: [22]We have adopted, for example, payment by installments.
M: We are very glad that you have such a friendly attitude.
W: It'll benefit both of us.

Questions 19 to 22 are based on the conversation you have just heard.
19. What's the main purpose of the man's visit?
正确答案：C
解析：寒暄之后女士切入正题：问男士想如何进行磋商，男士回答时提及目前的合同即将到期，讨论新的合同，综合关键词得出的答案是C。
20. What can we learn about the relationship between the two speakers?
正确答案：A
解析：选项为他们之间的关系，根据前一题中提到过的男士所说“目前的合同即将到期”及后文明示的“过去几年合作很好”，得出答案为A。B错在first，C错在long-term（这是此行目的之一，不是现实）
21. What's the woman's principle in foreign trade based on?
正确答案：B
解析：答案是直接听到的原词。C中的daily necessities是对原文needed goods的误解。
22. What new practice has been adopted by the woman's company?
正确答案：D
解析：选项为某公司的做法。D中的accepts delayed payment是原文adopt payment by installments的同义表达。
