比如，对于这道大作文题目，Should Smoking Be Banned in All Public Places?我们就能用18个单词来构思正反两方的观点。

首先，如果是觉得应该被禁止的，可以从Health角度写，词组可以写成smoking has a detrimental influence on physical health；还可以从money角度写， 词组可以用成smoking is money-consuming. 而如果你是不同意smoking 应该被禁止的话，也同样可以用这18个单词去构思。

第一个就是根据money这个单词联想到的整个国家或者社会的money，也就是economy，抽烟是有利于国家经济发展的，smoking can boost economy.因为它带来大量的税收（tax revenue））

第二，烟草工业的存在还能解决就业问题generate employment opportunities，第三，抽烟尽管危害身体健康，但是对人们的心理是有帮助的。可以从relax their bodies and ease their minds 出发写。

经多个题目验证，这18个单词所能拓展的词组和短语，能够在构思过程中给予大家绝大多数的灵感，也就是说，一篇文章中所需要的正反两方共6个观点中，用这个方法能构思出来的观点，至少有一半以上。这大大缩短的同学们在考试时因为构思而需要的时间，减轻了因为构思不足而导致的考试焦虑心情。
