4.呈现该话题正反方的观点
例如在写到男性和女性谁可以做更好的父母时可以这样开头：
At the mere mention of women governing the world, most of us may naturally form an unrealistic picture of a more peaceful world where the sun always shines. The other side of the picture, however, is just to the opposite.
在开头提出两种不同的观点，不同的读者可以根据自己对问题的看法进行思考，从而引发读者的探究心理，进一步思考这个问题从而得出结论。
5.引用名人名言、谚语等作为文章的开头
例如在写到先天跟后天哪一个更重要时：
“Genius is two percent inspiration and ninety-eight percent perspiration” is the opinion held by Edison. This remark has been confirmed time and again by more and more people.
“天才是百分之二的灵感，百分之九十八的汗水”是爱迪生的观点，而且反复被越来越多的人所证实，通过引用名人名言揭示了文章的主题，为下文很好地做了铺垫。
6.对将要讨论的话题进行定义
例如在写到Globalization时：
Globalization-the international spread of products, ideas and information-is bringing the world closer together. But globalization is not a new concept. For thousands of years, nations have roamed the earth in search of new markets and new sources of raw materials for their own industries.
关于"全球化"这个名词，考生并不陌生，但是如何用合理的语言来赋予它一个含义，这并非易事，上述的引言段就很好地做到了这一点，先是从字面上诠释了"全球化"的定义，进而又从实际生活角度赋予了它另外一层含义。
7.追根溯源法
即从题目给出的话题中找出这个现象产生的原因来扩展背景句。这种方法适合大多数的话题。
例如题目：
There are social, medical and technical problems associated with the use of mobile phones. What forms do they take? Do you agree that the problems outweigh the benefits of mobilephone?
话题是mobile phone, 所以考生可以从它产生的原因来考虑，就是科技的繁荣，而科技的繁荣，手机的广泛使用是在20世纪末，这样背景句就有内容可写了。当然要通过相应的句型来写，这个背景句就可以写成：
The late 20th century witnessed the boom of science and technology, which gave rise to a series of technological innovations, including the mobile phone.
再如另外一道题目
「 Nowadays, some universities offer students skills that assist them to find employment, but some people believe that the main function of a university should be to provide students with access to knowledge for its sake. What is your opinion? 」
这题要求大家讨论大学是提供职业技能还是传授知识。
从传统观点来看，大学是传授知识的地方，为什么会提出要传授技能呢?所以这里考生也可以用追根溯源法思考一下，大家肯定可以想到是由于找工作已经成为当今教育的目的之一了，所以很多大学就转移到以传授技能为主了。
As job-hunting has become one of the main purposes of university education,the majority of the universities tend to offer vocational trainings to prepare the students for their future career.
