做xdf的绿皮书,遇到了一些问题.有的题选对了,但是总觉得理解还欠全面,思路不那么清晰,对选项和题型没有敏感度;选错了的好一些都经常是我排除了三个选项,犹豫到最后还是选错了,其实正确答案也是我"心仪"很久了的对象啊!觉得很是郁闷!

第299题

Industrial accidents are more common when some of the people in safety-sensitive jobs have drinking problems than when none do. Since, even after treatment, people who have had drinking problems are somewhat more likely than other people to have drinking problems in the future, any employer trying to reduce the risk of accidents should bar anyone who has ever been treated for a drinking problem from holding a safety-sensitive job.

which of the following, if true, most seriously undermines the argument above?

A. Some companies place employees who are being treated for drinking problems in residential programs and allow them several weeks of paid sick leave.

B. Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.

C. Workers who would permanently lose their jobs if they sought treatment for a drinking problem try instead to conceal their problem and continue working for as long as possible.

D. People who hold safety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems

E. Some industrial accidents are caused by equipment failure rather than by employee error.

第291题

A light bulb company produces 2,000 light bulbs per week. The manager wants to ensure that standards of quality remain constant from week to week. The manager, therefore, claims that out of 2,000 light bulbs produced per week, 500 light bulbs are rejected. Of the following, the best criticism of the manager's plan is that the plan assumes that

A. light bulb manufacturers cannot accept all light bulbs that are produced

B. the overall quality of the light bulbs would not be improved if the total number of light bulbs produced were reduced

C. each light bulb that is reviewed is worthy of being reviewed

D. it is difficult to judge the quality of a light bulb

E. the 1,500 light bulbs that are accepted will be of the same quality from week to week

做题的时候，你要时刻关注文章的focus，先对选项做出有关无关排除，然后再在剩下的选项里选争取答案。

299题，focus是“有drinking问题”和“accidents”之间的关系。所以我们可以第一时间排除ABDE，因为A没有说到“accidents”，B没有说到drinking的问题，D的造成问题的原因也无关，E的equipment无关。

从另一个角度看，ABE都存在范围的问题。A的some说明的是一部分的公司，不能了解这个some对全部的影响，所以说了等于白说。B的many－－什么叫many？500个事故算不算many？但是如果drinking问题造成的是5000个事故呢？所以B的many对全局造成的影响我们也是不可知的。同理，E的some也是错的。

291题，也是一样，focus是质量和数量之间的关系。所以A的制造商、B的总数量变化（注意原文说的是现有的数量和质量的关系，而不是改变数量对质量的影响），CD的值得与否或判断，都不是答案。E在数量和质量之间建立起了联系，所以是假设答案。

MM，XDF绿皮书的题目，在逻辑大全里面都可以找到。请先下载逻辑大全（ 本区置顶贴中有链接），然后将题目的关键词到逻辑大全中去搜索，搜到题号以后，再到本区搜索，大部分大全的题目以前都讨论过了。这样你会更快的找到你要的答案。
