linlin的lsat(5)谢谢!!

第一套I
9. Free public education is the best form of education there is. Therefore, we must fight to ensure its continued existence; that is, we must be ready to defend the principle of equality of educational opportunity. Because this principle is we worth defending, it is clear that free public education is better than any other form of education.

Which one of the following illustrates the same weak reasoning as found in the passage?

(A) I love music, and that’s why I listen to it constantly. I have my stereo or radio on every waking minute. Since I play music all the time, I must really love it.

(B) Books are my most valuable possessions. My books are like my friends—each pleases me in different ways. Just as I would give up everything to save my friends, so too with my books.

(C) I would much rather be poor and respected than be rich and despised. To have the respect of others is far more valuable than to have millions of dollars.

(D) I have never been betrayed by any of my friends. They have been true to me through good times and bad. Therefore I will never betray any of my friends.

(E) Because every plant I have ever seen has green leaves, I have concluded that all plants must have green leaves. This looks like a plant but it does not have green leaves, so it cannot be a plant.
循环论证到底是个什么东东啊!!其他的选项还有什么论证错误吗??我怎么一点都看不出来呢?
12. If Country X does not intervene militarily in Country Y, then the whole region will definitely fall under enemy influence.

It most logically follows from the statement above that, if Country X does intervene militarily in Country Y, then the whole region.

(A) Will definitely fall under enemy influence

(B) Will probably fall under enemy influence

(C) Will probably not fall under enemy influence

(D) Will definitely not fall under enemy influence

(E) May or may not fall under enemy influence
(B)(C)为什么不对啊!!probably不行吗??

13. Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today’s employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class, Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation.

Which one of the following is an assumption that, if true, would support the conclusion in the passage?

(A) Today’s students are not higher achievers than the students of twenty years ago.

(B) Awarding too many honors degrees causes colleges to inflate grades.

(C) Today’s employers rely on honors ranking in making their hiring decisions.

(D) It is not easy for students with low grades to obtain jobs.

(E) Colleges must make employers aware of the criteria used to determine who receives an honors degree.

感觉是A但是说不清楚为什么是假设!


大家帮帮忙!呵呵!

1是循环论证,就是需要用结论来证明论据和论点.换言之,前提和结论互为前提。
2probably表示很可能的意思
3现在的“牛人”比以前的“牛人”更难以向顾主证明其卓越,因为过去的“牛人”凭“牛人”的等级就可以了,而现在的顾主对“牛人”的等级不太感冒了。原因是现在的学生中得到“牛人”等级的很多,所以学校一定要把得到“牛人”等级的人数控制一下。如果,现在的学生果然优秀,那么更多的人得到“牛人”就是应该的,而文中认为不应该给这么多“牛人”,那假设一定是,本来不应该有这么多牛人的,所以A是假设。

我的意思是,原命题不一定等与否命题,所以用probably表示可能性不行吗!may or may not不就是probably的意思吗??都表不确定性啊??
以下是引用cranberry在2003-4-27 20:22:00的发言:
2probably表示很可能的意思

may or may not
比probably好,如果退一步说
按照你说得probably有may或者may not的含义
那么probably not也是这个含义,所以b,c是一致的,所以都不对
那么e对,我就是如此笨的理解的

probably表示很有可能的意思. 程度上超过possible. 你可以这么理解, 题目告诉你一件事可能发生,也可能不发生, 你不能认为一种可能要大于另一种可能.

我记得有一道题与此题类似. 是说某些人中一部分如何如何. 一个选项是most of ...就是错的. 因为原文并没有讲程度. 而此题的probably就相当于most.

需要理解得这么细致呀,我觉得b和c都只说了两种可能之一,而e说得最全面,所以选e。
