　　条件3：o,y → w

　　所以Desk重漆之前一定不能为o或y

　　3、选项A、B一定不对，因为Desk重漆之后为b/t，违反g≥1.

　　选项D：y→w, 违反g≥1

　　选项E：t→t, 违反g≥1，故C对

　　A common defense of sport hunting is that it serves a vital　wildlife-management function, without which countless animals would succumb to　starvation and disease. This defense leads to the overly hasty conclusion that　sport hunting produces a healthier population of animals.　

　　Which of the following, if true, best supports the author s claim that sport　hunting does not necessarily produce a healthier population of animals?

　　For many economically depressed families, hunting helps keep food on the　table.

　　Wildlife species encroach on farm crops when other food supplies become　scarce.

　　Overpopulation of a species causes both strong and weak animals to suffer.

　　Sport hunters tend to pursue the biggest andhealthiest animals in a　population.

　　Many people have strong moral objections to killing a creature for any reason　other than self-defense.

　　答案：(D)

　　问题：下面哪一个，if true，最能够支持作者的宣称：sport hunting并没有产生一个健康的动物数目？

　　读题：对运动狩猎的一般辩护是它起了重要的野生生命管理的作用，没有它无数的动物将死于饥饿和疾病。这个辩护导致过分草率的结论：运动狩猎会产生更健康的动物数目

　　分析：

　　本题作者的宣称在问题中就已经告诉。问题是支持宣称：运动狩猎将不会产生健康的动物数目。直接支持就可

　　B.当其他的食物供应变的稀少时，野生种族蚕食农作物（如果这道题目让你去反对作者的宣称，你会选B吗？其实B是一个无关选项。B看起来象是对的，它吃农作物，对人类不利当然要狩猎。但是注意：原文中的宣称是狩猎带来更健康的动物数目，这两者根本就没有联系。）

　　D.运动狩猎者倾向于追捕最大最健康的动物。（D指出你把大的健康的捕完了，剩下老弱病残，怎么能说是产生更加健康的数目呢，与结论一致，为SUPPORT）

　　Two suits of battle armor worn by King Henry VIII were discovered, one from　the beginning of his reign in 1510 and the other from 1540. Although both suits　of armor were made for Henry VIII, the 1540 suit of armor was 40 pounds heavier　than the 1510 suit of armor.　

　　Which of the following, if true, contributes LEAST to an explanation of the　discrepancy described above?

　　Henry, although slim at the beginning of his reign, developed a bulky figure　because of massive weight gain.

　　During his reign Henry increased his arsenal of weapons because, despite his　popularity in 1510, by 1540 the English populace was becoming disenchanted with　his rule.

　　Although the style of armor was plain and severe in the beginning of Henry s　reign, he started the fashion of decorating armor with heavy and elaborate metal　pieces because of his love for ornamentation.

　　Henry ascended the throne while still an adolescent and grew three inches　during his first five years as king.

　　Because of the improved design of battle weaponry during the 1530 s, armor　was given a multilayered design so that the sharper and stronger weapons could　not pierce it.

　　答案：(B)

　　Government department head: We already have a code of ethics that companies　doing business with the department are urged to abide by. The fact that　virtually all of the companies have agreed to abide by it indicates that it is　successful. Therefore, neither stronger ethics regulations nor enforcement　mechanisms are necessary to ensure ethical behavior by companies doing business　with the department.　　

　　Which of the following, if true, casts most doubt on the department head s　conclusion?

　　The code of ethics applies only to companies that do business with the　department.

　　The code of ethics was instituted only after it was discovered that several　companies had committed serious violations of ethics in their business with　the　department.

　　A government investigation found that most of the companies that agreed to　abide by the department s code of ethics are not complying with it,

　　A survey of major companies found that several companies stopped doing　business with the department because they did not want to agree to abide by the　code of ethics.

　　A study of codes of ethics for companies found that the codes are most　effective when the top executives of companies that agree to abide by them are　fully committed to following them.

　　答案：(C)

　　问题：下面哪一个，if true，最反对department head 的结论？（由问题知，读题时当然要注意department head的结论是什么）

　　读题：政府部门的头：我们已经有了一个道德法规，与政府部门做生意的公司被要求遵守的道德法规。事实上所有的公司都同意遵守这个法规显示它是成功的。因此，更严格的法规管理或者执行机制都没有必要来保证这些公司的道德行为

　　分析：

　　很显然，department head的结论是由第5行Therefore引导：不需要更严格的法规管理和执行机制存在

　　原因: 所有公司都同意遵守问题为WEAKEN,答案达到的效果为: 大家都同意遵守不能表明就不需要严格执行机制.说到和原因、结论或他们之间不一样的就是答案原因关键词： 同意遵守

　　B.法规仅仅是在几个公司与政府部门做生意时严重触犯道德后被制定的。

　　C.政府调查发现：大多数同意遵守道德法规的公司没有遵守它。直接反对原因, 他们都是口头上同意,但是实际上并没有遵守

　　D.主要公司调查发现：几个公司停止与政府部门做生意，因为他们不同意遵守道德法规（法规带来的不利性，与要不要执行机制无关）
