要说搜集句子，首先要有一个坚强的后盾，那么这些后盾从哪里来呢？
这要看你需要什么句子，如果是找每一段开篇点题的句子，最好还是找一些文学性比较强的东西，比如说一些给白领看的经济类文章，我们经常提到了的[经济学人].The.Economist.就属此类。要想寻找经济学家的话最好还是去verycd这个网站http://www.verycd.com/topics/2727001/ 这里就是一个很好的选择。比如说无老师就从2008年11月15日这一期的第12页找到了一个很好的句子，很适合当文章的开头。Asked what China will do to rescue the world from financial turmoil, its officials these days have a boilerplate answer：its greatest contribution will be to keep its own economy running smoothly.我们把它放在Do you agree or disagree with the following statement? Many teachers assign homework to students every day. Do you think that daily homework is necessary for students? Use specific reasons and details to support your answer.这个作文题目之下，就可以改写成Asked what teachers will do to improve their students, the response in high schools have a boilerplate answer：the greatest contribution of homework will be to keep its their students appreciating their knowledge entirely.
那么我们提炼一下Asked what …… will do to ……, the response in …… have a boilerplate answer：the greatest contribution of …… will be to keep its their …….就是一个十分优秀的作文开头模板。
我们也可以从同样是2008年11月15日这一期的120页找到Further evidence of emerging markets’ potential comes from the experience of Britain’s AstraZeneca in China.这一句只要稍加修改就可以变成一个非常优秀的2-4段的段落开头，首先把他模板化Further evidence of …… comes from the experience of …… in …….然后再加入一点倒装句式来证明我们的文学水平Not only does ……come from the experience of …… in ……., but (also) evidence of ……subsequently(further) prove……这样一个优秀的论证段的段首句模板就完成了。
