正在准备gre考试的同学，在平时的模拟考中，肯定也对gre写作有所了解，gre写作要有思路，要注重gre写作技巧的运用，澳际小编为大家介绍一种有关论据的gre写作教程，希望对大家有所帮助。

　　以下澳际小编为大家介绍的gre写作教程是关于论据中类比法的gre写作技巧，通常来说，在GRE写作中选择论据有如下几个思路：一是例证法;二是引经据典法;三是引用权威法;四是引用数据;五是类比法。这里想就类比在GRE写作中的应用进行一下分析，希望大家可以在gre写作中取得高分。

　　一、类比在ISSUE中的应用。

　　ISSUE是立论文，也就是说，我们需要用理由或例子去支持自己的观点。在英语中有个单词叫comparable，直译的话是可比较的，其实它等同于similar(相似的)这个单词，因为在西方文化中，只有相似的东西才具有可比较性。因此相似性也就成为了整个类比关系的前提和基础。

　　个人认为，类比(Analogy)在上述提到的五种论据方法中是最有逻辑性的，使用得当可以省力又出彩地证明观点。它有点像中学时代所学的几何题，解题的关键不在论证的过程，而是添加一条辅助线。只要找到合适的辅助线，论证就是水到渠成的事了。当我们想论证一个抽象复杂的命题A——B 时，我们可以选择一个具体形象并且不需要证明的——D来作为辅助线，然后就把原本复杂的A——B的论证过程替代为论述AB和CD之间的相似性就可以了。这里需要指出的是，所谓具体形象且不需要证明的CD其实指的就是事实或常识。所以类比关系建立的难点就在与选择合适的CD。我们来看个例子。

　　The Negro has callus growing on his soul and it’s getting harder and harder to hurt him there. That’s simple law of nature. Like a callus on the foot in a shoe that’s too tight. The foot is nature’s and that shoe was put on by man. The tight shoe will pinch your foot and make you holler and scream. But sooner or later, if you don’t take the shoe off, a callus will form on the foot and begin to wear out the shoe.

　　It’s the same with the Negro in America. That shoe—the white man’s system—has pinched and rubbed and squeezed his soul until it almost destroyed him. But it didn’t. And now a callus has formed on his soul, and unless that system is adjusted to fit him, too, that callus is going to wear out that system.

　　很显然在这段文字中，作者想证明的是全文第二段的最后一句话：And now a callus has formed on his soul， and unless that system is adjusted to fit him, too, that callus is going to wear out that system.(现在黑人的灵魂中已经产生了老茧，除非白人的统治体系能调整以适合他们，否则老茧将使这个体系土崩瓦解。)简而言之，就是黑人终将冲破白人统治。

　　黑人反抗白人统治获得解放这无疑是个非常抽象复杂的命题。采用一般的例证法，学生们都不约而同能想马丁。路德。金。且不管例子雷同与否，事实上，很少有人能真正清楚又准确地写出马丁。路德。金的具体事迹来证明这个观点。甚至还有学生会想到曼德拉或奥巴马来证明，实在有失偏颇。

　　现在我们再来看上面这段文字。作者很巧妙地找了CD，即 foot(nature)——shoe( put on by man)之间的关系。 鞋子小了，脚穿着会疼，如果不及时脱掉或调整，脚上会产生老茧。如果鞋子继续对脚进行禁锢，那么总有一天，脚会把鞋子穿破。这是一个再平常不过的道理，不需要再花时间进行论证，括号里的就是AB和CD间的相似性，轻松论证了这个复杂的命题，这就是类比的魅力。

　　下面再给大家一段文字来体会类比的妙用。

　　“It is unrealistic to expect individual nations to make, independently, the sacrifices necessary to conserve energy. International leadership and worldwide cooperation are essential if we expect to protect the world’s energy resources for future generations.”

　　Another reason why an international fort is required is that other problems of an international nature have also required global cooperation. For example, has each nation independently recognized the folly of nuclear weapons proliferation and voluntarily disarmed? No. Only by way of an international fort, based largely on coercion of strong leaders against detractors， along with an appeal to self-interest, have we made some progress. By the same token, forts of individual nations to thwart international drug trafficking have proven largely futile, because forts have not been internationally based. Similarly, the problem of energy conservation transcends national borders in that either all nations must cooperate, or all will ultimately suffer.
