先看政府和大公司如何改善环境，政府为促进环境的改善，已经采取了很多的措施（adopt feasible measures），如严厉惩罚污染环境的人和机构，提倡使用环保袋，少用一次性产品（disposable products），另外大公司可以投入资金（investment）寻求探索新能源，彻底解决汽车尾气排放等污染问题。正文前两段结构安排如下：
{原创范例} In an attempt to preserve the environment, the related departments have already settled down a range of effective regulations such as severe punishment, to promote the improvement of environment.
Besides, with ample funds, the large corporations are qualified to exploit and create new products applying clean energies, thus eliminating the contaminations stemming from old energies.
最后，提出个人在保护环境中也能起到关键作用（Perform an essential role in），从小事做起。请看下面结构安排：
{原创范例} Apart from governments and companies, the individuals are well advised to endeavor to make contributions to this campaign, such as refusing to use disposable products.
通过上述正文的论证，我们可以在结尾段得出结论，只有三方共同努力（make joint efforts），对于环境保护才能起促进作用。
2. Housing shortage in big cities can cause severe social consequences. Some people think only government action can solve this problem. To what extent do you agree or disagree?
同样通过审题，我们可以对正文的结构做如下安排，先写一段让步段，承认题干的论点的合理性即“government action can combat this problem”，再举两个反例，即两段反对意见，除了政府政策外，人们对房子的观念（people’s awareness）以及一些房产公司的举措对解决这个问题都有决定性的作用(key determinant)。通过上述brainstorming, 我们可以写出全篇文章的框架：
