SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文:W: Good morning. Sit down please, Mr. Johnson.
M: Thank you, madam.
W: I have read your letter here. You seemed to have done very well at school. Can you tell me something about your school work?
M: As you can see, my strongest subjects were arts subjects. My best subject was history and my second best was geography. However, my favorite subject was math, and the results I got in the math paper were quite reasonable.
W: That's true. Now, can you tell me why you think these subjects will help you in this job?
M: Well, madam, I understand that you manufacture computers, prepare software, and advise clients on how to use them. Is that right?
W: That's right.
M: And I've been told that working with computers needs a logical mind rather than great skills in mathematics. That's especially true, I believe, when it comes to writing programs. So I think my results show that I have some ability in logic and in mathematics as well.
W: So, you would like to write material for computers, would you?
M: Yes, madam. That's what interests me most about computers - writing programs, but I think the computer industry itself is still expanding enormously. I'm sure that career prospects in the industry would be very good no matter what sort of job I went into.
W: I see, well, thank you. I've enjoyed our talk. We'll be writing to you.
M: Thank you, madam. Good morning.

哈丁争论说,人们使用共同拥有的(即对任何使用者都开放的)牧场比使用私人的牧场更不注意。每个放牧者都有过度使用公用地的冲动。因为从中获得的利益将归于个人,而由于过度使用土地引起的土地质量下降的成本由所有使用者分摊。但一项研究比较了17亿英亩的公用牧场和33亿英亩的私人牧场,结果表明公用牧场的条件更好。以下哪一项如果是正确的并为放牧者所知,将最有助于解释该项研究的结果?()
A. 对于私人牧地来说,过度使用的成本和收益都落在使用者个人身上。
B. 归于个人使用者的土地质量下降的成本,对于公用地来说更不容易度量。
C. 一个过度使用公用牧地的个人可能比其他使用者取得更高的收益,因此他会获得一种竞争优势。
D. 如果公用地的使用者即使只是稍微地过度使用,其他的使用者就会变本加厉地这样做,其结果是每个使用者的成本都超过了收益。
