Question 17-18
(这个题目的题干我根本没有读懂！)
Teacher: Journalists who conceal the identity of the sources they quote stake their professional reputations on what may be called the logic of anecdotes. This is so because the statements reported by such journalists are dissociated from the precise circumstances in which they were made and thus will be accepted for publication only if the statements are high in plausibility or originality or interest to a given audience – precisely the properties of a good anecdote.

Student: But what you are saying, then, is that the journalist need not bother with sources in the first place. Surely, any reasonably resourceful journalist can invent plausible, original. or interesting stories faster than they can be obtained from unidentified sources.

17. The student's response contains which one of the following reasoning flaws?

(A) confusing a marginal journalistic practice with the primary work done by journalists

(B) ignoring the possibility that the teacher regards as a prerequisite for the publication of an unattributed statement that the statement have actually been made

(C) confusing the characteristics of reported statements with the characteristics of the situations in which the statements were made

(D) judging the merits of the teacher's position solely by the most extreme case to which the position applies

(E) falsely concluding that if three criteria, met jointly, assure an outcome, then each criterion, met individually, also assures that outcome

18. Which one of the following, if true, most strengthens the teacher's argument?

(A) A journalist undermines his or her own professional standing by submitting for publication statements that, not being attributed to a named source, are rejected for being implausible, unoriginal, or dull.

(B) Statements that are attributed to a fully identified source make up the majority of reported statements included by journalists

in stories submitted for publication.

(C) Reported statements that are highly original will often seem implausible unless submitted by a journalist who is known for solid, reliable work.

(D) Reputable journalists sometimes do not conceal the identity of their sources from their publishers but insist that the identity of those sources be concealed from the public.

(E) Journalists who have special access to sources whose identity they must conceal are greatly valued by their publishers.

24. Mainstream economic theory holds that manufacturers. in deciding what kinds of products to manufacture and what form those products should have, simply respond to the needs and desires of consumers. However, most major manufacturers manipulate and even create consumer demand. as anyone who watches television knows. Since even mainstream economic theorists watch television, their motive in advancing this theory must be something other than disinterested concern for scientific truth.

The claim that manufacturers manipulate and create consumer demand plays which one of the following roles in the argument?

(A) It is one of the claims on which the conclusion is based.

(B) It is the conclusion of the argument.

(C) It states the position argued against.

(D) It states a possible objection to the argument's conclusion.

(E) It provides supplementary background information.

17、B 。文中老师说“记者引述某个说法时如果隐去材料的来源，那么他在利用所谓的逸闻的逻辑而使他的职业声誉冒险”，然后说明原因。而学生直接导出记者可以不关心材料的来源进而可以编故事的结论。老师讲的是真，但隐去来源，学生直接讲假，学生的确忽略了老师讲法可能是要以所引述的东西应该是真的作为前提。

18、A。就是原文中老师讲法的反面例证。

24、我想需要先搞清文中的结论是什么。我的理解是最后一句是结论，即作者认为，主流经济学家宣扬他们理论的动机一定不是出于对科学真理的无私追求。既然结论是这样，题目中的BCD都不对，只有A和E可以考虑。E是说它提出了补充性的背景信息，但通过文章，可以清楚地看出，这句话才作者立论的一个基础。

一块砖头，大家赶快扔玉呀。

谢谢cranberry的回答，十分精彩。看来逻辑牛牛都是用ry结尾的。
