反证法的思路是“如果不（接受本段的论证点），会（产生什么样的结果）”，通过这样的方式来对问题进行更加深入的思考。举个例子，对于这样的题目：Students should always question what they are taught instead of accepting it passively. 我们可以提出这样的分论点：Students in fields such as law and political science should think critically about current legal systems. 学习法律和政治学的学生应该学会质疑当今存在的各种法律法规的正确性。
通过反证法可以进行思路扩展：如果他们不这样做的话，会发生什么，从而提升论证的深度：
Students in fields such as law and political science should think critically about current legal systems. While law students must learn to appreciate timeless legal doctrines and principles, they should continually question the fairness and justification of current laws. Without such skepticism, our laws would not evolve to reflect changing societal values and to address new legal issues brought by new technologies, fox example AI and self-driving cars.
写作是思考的反映，经历什么样的思考就会写出什么样的文章。因此，要真正写好一个段落一篇文章，除了采取以上几种方法之外，还要学会训练自己的思考能力，对日常发生的大小事件、别人的观点，要多从不同层面思考它们的前因后果、成立的前提、适用的领域等，让写作水平和思维能力同步提升。
