在对我们研究进行的叙述过程中，利用证据和实例来阐释说明是一个重要组成部分。的确，作者在论文中所提供的说明，表意明确的话，能够帮助作者强化研究结论的准确性；而不恰当的表达，反而可能让读者对文章的研究结论心生怀疑。因此，使用适当且符合逻辑的句子引导读者理解论文的研究内容，是撰写论文时十分必要的能力。

1. 利用证据和实例的最佳时机

证据和实例为我们的说明打下一个稳定的基础。没有实例辅助的话，论文的结论缺乏可信度。不论是流水帐般的实例验证，还是无法提供任何材料或信息的来源，二者其实都一样糟糕的。因此，当你介绍实例时，需要确保适时睿智地挑选证据，并使用适当和清楚的句子来说明这个实例能够论证你的结论。当你在写作论文有以下几种需要时，你应该要介绍你的实例论证：

• 说明“非普遍知识”的内容时 ;

• 根据某个数据来引导结论、推论或说明涵义时;

• 需要澄清一个先前的叙述，使用范例说明能够更加清楚的时候;

• 需要找出某个类别的代表性范例;

• 想要区分概念时;

• 想要利用某个情况来强调某个特点时。
