GMAT寫作邏輯因果聯(lián)系的方法

　　為了讓大家能夠更好的學(xué)習(xí)GMAT的寫作方法，就需要大家對邏輯方面的知識有一定的掌握，下面小編就為大家整理了GMAT寫作邏輯因果聯(lián)系的方法，希望能幫到大家!更多內(nèi)容請及時關(guān)注我們應(yīng)屆畢業(yè)生考試網(wǎng)!

　　例：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?

　　首先，讀GMAT考試邏輯題題干，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(后文均用“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(tuán)體組織人在非戰(zhàn)時進(jìn)行對抗B國的軍事訓(xùn)練;并且，法律禁止美國公民在非戰(zhàn)爭狀態(tài)下參與對他國的軍事對抗行為;

　　所以：該組織應(yīng)被調(diào)查和指控。

　　GMAT攻略邏輯題的解法思路：我們要反對“因為”，那么答案一定要對“因為”的內(nèi)容進(jìn)行質(zhì)疑。由于這里的“因為”有兩句，所以為我們篩選質(zhì)疑哪個“因為”增加了難度。但實際上，我們要質(zhì)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(chǎn)生質(zhì)疑的選項。

　　答案：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.

　　很顯然，c 恰好是用“該團(tuán)體只是訓(xùn)練人員已備戰(zhàn)時使用，并非是在非戰(zhàn)爭狀態(tài)下對B國進(jìn)行軍事對抗”反對了第一個因為，所以直接選擇就好了。

　　當(dāng)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(zhì)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，并沒有錯。因此，只有c 正確。

　　GMAT邏輯題的解法林林總總，不過用因果聯(lián)系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(zhàn)中去。
