常用作文优秀素材【三】
也叫举例子。就是用列举事实的方法，把比较复杂的事物或抽象的事理说得具体明晰、通俗易懂。例如《向沙漠进军》一文中，就举出了新疆和内蒙古沙荒区治沙成功的事例，说明“沙漠是可以征服的”。常用作文优秀素材【四】
引证法也叫道理论证，是通过引用名人名言、古诗文名句、反映科学规律的俗语谚语警句等来证明自己观点正确可信的一种论证方法。
引证法在考场或平时练笔写作中的使用频率仅次于例证法。由于引证法引用的是世人公认的思考结晶，能够深刻地反映事物的本质已为无数事实所证明，所以具有巨大的说服力。
怎么用好引证法呢？
1、所引用的名言警句等针对性要强。每句名言都产生于特定的背景，都应用于特定的交际目的，即使谈同一个问题，也有不少名言可供选取。要仔细分析每个道理论据的特有功能，将它引用到最恰当的语言环境之中。
例如：强调立志的重要性，要选用“三军可夺帅也，匹夫不可夺其志。”强调志向高洁远大，要选用“燕雀怎知鸿鹄之志”，某同学沉湎于上网，要选用“玩物丧志”，某同学不能只持之以恒、一暴十寒，要选用“有为之人立长志，无为之人常立志。”
2、要简洁，不宜过多。议论是在发表自己的见解而不是在介绍他人的见解。引用他人的话，目的是为了让读者更加信服自己的话，自己的话应是议论的主体，应是全文最醒目的部分。过多的引文，很容易将自己的分析淹没。
3、要注意直接引用和间接引用的区别。直接引用务求文字、甚至标点均准确无误；间接引用只须述其大意，但要注意人称的转换。
常用作文优秀素材【五】
所谓类比，就是借助某个或某几个类似的故事、实例或写作者安排的情境，进行由此及彼的推理。
用于类比的事物大致有这么几种：古今中外的史实、神话传说、寓言、写作者自己创设的情境等。
运用类比要注意所选取的“类体”要同类，不能相对或相反；在类比之后要剖析，要善于揭示，一语破的，一刀见血。
