例证法是写作议论文最常用的论证方法,运用这种论证方法,关键是要掌握用例艺术,把握选例、引例、叙倒、议例四个环节。一、选例——得当选例,这是运用例证法的最关键的一步,例子是否得当直接影响到整篇文章的成败。那么,什么样的例子才算“得当”呢?第一,例子要有效度。它必须切中论题,瞄准论点,具有“向心力”,是正中靶心的“十环”材料,而不是那种与论点无关的“脱靶”材料或与论点关系不大的“擦边”材料。第二,例子要有力度。它应该真实、典型、新鲜,能“挑大梁”,是具有强烈说服力和感染力的“尖端”材料。第三,例子要有广度。它应该在类型上有区别,体现不同的角度,有正面的,有 The exemplification method is the most common method of argumentation for writing argumentative articles.
