请教LAWYER有关 WEAKEN中的几种特殊形式

WEAKEN


条件型结论:结论带条件(即为充分必要)。WEAKEN的方法显示充分条件成立,必要条件可以不成立。或举反例,或提供有关信息。


不是很理解。哪位NN能帮忙举个例子


比如:显示充分条件成立,必要条件可以不成立


是不是81题的B答案就是呢?


其他俩中。。请帮忙举例!!


多谢!!

Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.



Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?



(A) Although it sells all of the telephones that it produces, Mammoth Industries’ share of all telephone sales has declined over the last year.


(B) Mammoth Industries’ average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.


(C) Advertising has made the brand name of Mammoth Industries’ telephones widely known, but few consumers know that Mammoth Industries owns this brand.


(D) Mammoth Industries’ telephone is one of three brands of telephone that have together accounted for the bulk of the last year’s increase in sales.


(E) Despite a slight decline in the retail price, sales of Mammoth Industries’ telephones have fallen in the last year.



此题中的结论是不是就是 条件型结论:结论带条件(即为充分必要)


那么 In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.


红的为 充分 条件  , 后面绿色为 必要条件 呢》??


那么 答案 E 的类型 应该如何解释呢??



多谢!!



是不是NN都去度假了!!

这个不是充分必要型结论。充分必要型结论肯定有充分必要指示词,参考lawyer写的《充分必要指示词》,在置顶的资料贴里。基本囊括了所有的指示词了,没有这些词的就不是充分必要型结论。

那应该按照什么思路来思考呢??能不能麻烦你给出推论过程,因为看到有位朋友说是 削弱 必要条件。。。?


再谢!


1.introduce a sufficient condition: if/when/whenever/every/all/any/people who/in order to/to


这里不是有IN ORDER TO 吗??

in order to/to非充分也非必要条件(我记得以前问过LAWYER这个问题:),如果说MUST BY A,TO DO B,那么A为必要条件(削弱的是必要条件,即不用A也可B);


如果只是BY A, TO DO B,这里没有任何充必或必要条件在内,削弱应该是BY A也达不到B(只是形式上类似于充分条件出现,而必要条件不出现)。


此题中的结论是不是就是 条件型结论:结论带条件(即为充分必要)
那么 In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.

那么 答案 E 的类型 应该如何解释呢??


如XY所言,这句话中没有充要条件指示词。


如果硬要套个公式的话:),E是它因削弱:(前提:已有强大的广告攻势),去年这家公司的产品价格走低,但销售仍然不好。(一般来说价格低应该卖得更好才对),说明价格低和强大的广告攻势都没能提升这家公司去年电话的销量,那么在其它条件都没有变化的情况下,在可预期的将来,这家公司的销售也不见得就能上去,因此削弱结论。

1。对于特殊类型,如果能用特殊办法较易找到答案,就用特殊办法,如果用普通办法较易理解,就用普通办法,我提供的特殊办法只是提供另外一种解题的途径,在你无法容易掌握的情况下,建议用普通办法。


2。该题携隐和ring_cheng说的都对。其实83题的答案E指出该产品的市场已饱和,故增加产量并不能增加销售量。故削弱结论。

先谢谢各位NN,


我的理解


1。充分必要型结论,既要有充分指示词,也要有必要指示词。


2。就否定结论而言,文中 “In order to take the advantage of this increase, Mammath....... of this product" 是结论。


对吗???请再指正!
