學GMAT小竅門：邏輯題要找因果聯繫

今天為大家整理了一些GMAT邏輯題的解題小竅門：找出因果聯繫。希望可以為各位正在備考GMAT的同學們帶來幫助~接下來，就跟著我一起來學一學這個小竅門吧！

GMAT小竅門：找出因果聯繫

GMAT邏輯題的解法有很多種，在閱讀GMAT邏輯題例題時，尋找原文中的因果關係，即“因為和所以”，不考慮其真正的邏輯關係如何。即使是並列關係，在小庫看來也可以表達為因果。這種方法對於GMAT邏輯題的解題很有幫助。這種GMAT邏輯題的解題方法也可以叫請 “前提和結論”。

下面我們就此來一篇真題例題，詳細的講解如何用提幹和信息分析的方法來解GMAT邏輯題。

GMAT真題例題

An investigation must be launched into the operations of the private group that is training recruits to fight against the Balaland Republic. The U.S. Neutrality Act plainly forbids US citizens from engaging in military campaigns against any nation with which we are not at war. Since no war has been declared between the United States and the Balaland

Republic, we should bring charges against these fanatics, who are in open defiance of the law.

Which of the following, if true, would most weaken the argument above?

小編說：首先，讀GMAT邏輯題題幹，知道這是weaken題。請立刻在腦海中想到答案就是最有效“反對”前提(後文均用“因為”代替)的一個。按此思路，我們就要找到“因為”。

此篇GMAT邏輯題原文的意思：因為：某團體組織人在非戰時進行對抗B國的軍事訓練;並且，法律禁止美國公民在非戰爭狀態下參與對他國的軍事對抗行為;

所以：該組織應被調查和指控。

GMAT邏輯題的解法思路：我們要反對“因為”，那麼答案一定要對“因為”的內容進行質疑。由於這裡的“因為”有兩句，所以為我們篩選質疑哪個“因為”增加了難度。但實際上，我們要質疑的不是法律，所以，第二個因為就可以排除在答案之外。因此，你就要去在5個選項中找存在對第一個因為產生質疑的選項。

a. The Balaland Republic is currently engaged in a bloody and escalating civil war.

b. Diplomatic relation between US and Balaland were severed last year.

c. The recruits are being trained to fight only in the event the US goes to war against Balaland.

d. The training of recruits is funded not by US citizens, but rather by a consortium of individuals from abroad.

e. Charges cannot be brought against the private group that is training the recruits unless an investigation is first launched.

正確答案：c

小編說：

當然，我們最好也去看一下其他GMAT邏輯題的選項，以防備自己的疏漏。a/b選項不能質疑，反而使支持，c在文章中沒提到，e和第一個因為不相干。而且原文第一句就說了是investigation，並沒有錯。因此，只有c正確。

GMAT邏輯題的解法林林總總，不過用因果聯繫的方法解題也是很迅速的，這種GMAT邏輯題的解法在很多場合很奏效，大家可以參考運用到GMAT邏輯題的實戰中去。

GMAT邏輯真題

10(Z). A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the greatest price the market will bear when they have such a product. But large profits on the new product will give competitors a strong incentive to quickly match the new product’s capabilities. Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

In the argument above, the two portions in boldface play which of the following roles?A. The first is an assumption that forms the basis for a course of action that the argument criticizes; the second presents the course of action endorsed by the argument.

B. The first is a consideration raised to explain the appeal of a certain strategy; the second is a consideration raised to call into question the wisdom of adopting that strategy.

C. The first is an assumption that has been used to justify a certain strategy; the second is a consideration that is used to cast doubt on that assumption.

D. The first is a consideration raised in support of a strategy the argument endorses; the second presents grounds in support of that consideration.

E. The first is a consideration raised to show that adopting a certain strategy is unlikely to achieve the intended effect; the second is presented to explain the appeal of that strategy.

正確答案：B
