M: How much did it cost?
W: About forty-five thousand dollars.
M: Forty-five thousand dollars! For a one kilogram weight! That’s more expensive than gold. Is it really worth that much?
W: I’m sure it is. Industries depend on our government agency to monitor the accuracy of scales, so that when they buy and sell their products there’s one standard. Think of the drug industry, for example: those companies rely on high accuracy scales to manufacture and package medicine.
Questions 19 to 21 are based on the conversation you have just heard.
19. What is the conversation mainly about?
【解析】選[A]。選項都是一些總結性的詞句表明該題可能就對話的主旨或大意提問。由對話開頭就提到的some questions about the new official standard weight that you purchased可判斷該對話是圍繞“新的標準測重砝碼”展開的，故選[A]。[B]和[C]都是針對對話中it was made of poor quality metal that was too porous — it absorbed too much moisture設的干擾項。[D]在對話中沒有涉及。
20. How is the weight used?
【解析】選[B]。選項表明該題可能考查某一個事物的用途或作用。[C]中的atmosphere與選項中多次提到的scale，metal，weight等詞關系不大，故可初步排除。由對話中Dr. Thomas的回答... use it to check the scales all over the country可直接得出答案是[B]。[D]是根據對話中的higher quality metal設的干擾項。
21. What does Doctor Thomas probably think about the cost of the new weight?
【解析】選[D]。選項表明該題是就某物是否值許多錢提問。[A] 和[C]的觀點完全相反，[B]持中立態度，[D]說“該事物擁有的重要功能來說是很合理的”，看問題全面、客觀，這樣的選項往往是答案。當對話中女士對該工具是否值那么多錢提出疑問時，Dr. Thomas的回答是I’m sure it is，而后又舉了藥品工業的例子說明標準測量砝碼的重要功能，故[D]正確。Conversation Two
M: Hi, Grace. Mind if I eat lunch with you?
W: No. Mr. Evans, not at all.
M: Thanks. I just heard that you’re studying nutrition and you’ve got quite a bit of experiences working in the cafeteria, so I wonder if you will be interested in a small project we are doing this term.
W: What’s the project all about?
M: More and more students have been deciding not to buy the meal here and we want to attract them back. So I want to hear what students would like. Your job would be to find out.
W: Well, if the menus were changed, then maybe I wouldn’t have to listen to so much criticism.
M: That makes you perfect for the job. Would you be interested?
W: I’m not sure. What sorts of changes are you thinking of?
M: I’d like to make some changes in the way we prepare our food. For example, just look at what we have to choose from today. You got a fried hamburger and I got fried chicken. They both contain too much fat.
W: But you’d better not get rid of them. They’re everybody’s favorite.
M: Well, we can certainly keep them, but we need to give the people who are health-conscious some choices. For example, we could also prepare chicken without the fatty skin and serve it on some rice with a light sauce. Do you think that would appeal to students?
W: Well, I’d like that. You’re right. You’d better find out what others think. Sorry, I’ve got to get back to work. I’d like to hear more though. I’ll drop by your office later.
M: OK, see you then.
Questions 22 to 25 are based on the conversation you have just heard.
22. What are the two speakers talking about?
【解析】選[B]。選項表明該題很可能是就雙方談論的話題提問，且談論的話題與cafeteria有關。根據對話中男士所說的I’d like to make some changes in the way we prepare our food可判斷[B]正確。[A]和[C]的內容在對話中均沒有涉及。[D]是根據對話中的working設的干擾項。
23. What does the man want the woman to do?
【解析】選[D]。選項表明該題很可能就某人的工作或任務提問。選項[A]、[C]、[D]都與食物有關，而[B]沒有涉及到食物，與其他三項差別較大，故可初步排除。由對話中男士所說的I want to hear what students would like. Your job would be to find out可推知Mr. Evans是要Grace調查學生喜歡的食物，這與[D]意思一致。[A]是針對對話中的fried hamburger和fried chicken設的干擾項。
24. What does the man suggest the cafeteria do?
【解析】選[C]。選項表明該題可能考查某人對食物的建議。[A]、[C]、[D]都提到了食物的配料或成分，[B]只提到了食物的價格，與其他三項明顯不同，故可初步排除。由對話中的a fried hamburger ...fried chicken...both contain too much fat推斷，男士建議女士應該做一些脂肪含量少的食物，這與[C]意思一致。[D]是強干擾項，男士只是拿這些油炸食品舉例，告訴女士應該增加產品種類。
25. How does the woman think of the man’s project?
【解析】選[C]。根據選項推斷該題可能考查某人的態度。前三項都屬于一種明確的態度，[D]Indifferent意思為“漠不關心的”，與其他三項明顯不同，很可能不是答案。由對話中女士所說的What’s the project all about?及I’d like that可推知女士對男士的項目很感興趣，故選[C]。考生應注意含有somewhat，certain等詞的選項往往是答案。
