第一种文章(前提结论结构): A(事实)-前提结论->B(推测)
第二种文章(因果结构): A(事实)<-因果-B(推测)
第三种文章(变态结构): A(事实)-前提结论->B(推测)表面为第一种
实为的二种即 A(事实)<-因果-B(推测)
那位NN 能帮解释如何分析下面这题呢? 哪句是A, 哪句是B? 是为什么不是前提结构呢?如果有更详细的介绍就好了。
1. Artificial seaweed made of plastic has been placed on a section of coast in order to reverse beach erosion. The inventor of the seaweed has concluded that the recent buildup of sand on that section of coast proves that the artificial seaweed reverses beach erosion.
Which of the following, if true, world most seriously weaken the inventor’s conclusion?
(A) The amount of recent sand buildup on that section of coast was less than had been predicted on
the basis of the results obtained in controlled experiments.
(B) Because artificial seaweed would be buried eventually by additional sand deposits on the coast,
more artificial seaweed would need to be put in place every four years.
(C) Artificial seaweed of another material which had been previously developed by the inventor
failed to add sand to coastline in past trials.
(D) The amount of recent sand buildup on that section of coast is the same as the amount of recent
sand buildup on otherwise very similar sections of coast without artificial seaweed.
(E) The amount of recent sand buildup on that section of coast, although considerable, is not yet
enough to replace the amount lost during storms on that section of coast in the last twenty years.
我不知道这样去归类究竟有什么意义,难道LZ看汉语的时候也要划分主谓宾定状补吗?这个句子非常浅显的:一个东东设计来达成某个目的,在用这个东东的地方出现了这个目的达成的一些标志,所以发明这个东东的家伙说他的发明是有效的云云。问怎么样才能打这个家伙的耳光?
我觉得选D
这应该是一个有因无果,即:使用了有人工海藻的地方并不比没有人工海藻的地方buildup sand更多,从而反对原文结论。
不过分析到底属于哪一类我就不会了,因为一直归不来,所以干脆就不看。我觉得归类是那种看了无数遍题目的人才能够达到的境界……
大家说费费的逻辑网络课堂对于建立GMAT逻辑思路有用么?
我有那东东,听着觉得挺有条理的,不知符合不符合现在题的思路?
还望指点迷津!
谁是A,谁是B,个人感觉比较复杂。看了陈向东书里面,该书也把逻辑推理分为(B,A型),和(A,B型),其中先发生的记作A,后发生的记作B。理论上是如此。但实践中感觉十分复杂,也不便于作题。
个人认为,把题干中所给提出的前提叫做A, 题干的结论叫做B。整个推理过程就是A-->B的过程。这样分析相对简单较易行。80%左右的题,都是围绕A-->B的过程展开。按那些大N的分法,容易把人分糊涂。统称为A-->B的分析有个最大优点是,分清题干和结论就好推导,而且不用为谁是A,谁是B饶来饶去。个人感觉,不当之处,尽请指导!
这道应该算是一道 入门题,用自己的简单的逻辑就可以解决
“东东设计来达成某个目的,在用这个东东的地方出现了这个目的达成的一些标志,所以发明这个东东的家伙说他的发明是有效的云云。问怎么样才能打这个家伙的耳光? ”
所言即是了
对与高难度的题目 不清楚
