在原因段的论述中，建议考生们在每列举一个原因后记得用示例或者因果对于列举的原因继续展开讨论。每个原因间用列举的连词隔开。比如：
In my opinion, most people commit crimes because they want something they cannot have. Advertising intensifies the desire for luxury goods and celebrity lifestyles, and although it is necessary to promote sales and improve the economy, it can encourage feelings of greed and jealousy. In addition to this, young people especially are vulnerable to peer pressure. For instance, they may be influenced by their friends to start taking drugs or stealing cars for fun.
在上面这个例子中，作者罗列了犯罪的2个原因，即贪婪和同辈的压力。在原因表达以后，作者分别各自用了一个因果和例子来继续发展。请注意，个原因后的那个句子是解释贪婪的原因，属于因果法;而第二个原因后作者是通过举例的方式来进一步论述。
