在原因段的論述中，建議考生們?cè)诿苛信e一個(gè)原因后記得用示例或者因果對(duì)于列舉的原因繼續(xù)展開討論。每個(gè)原因間用列舉的連詞隔開。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.

在上面這個(gè)例子中，作者羅列了犯罪的2個(gè)原因，即貪婪和同輩的壓力。在原因表達(dá)以后，作者分別各自用了一個(gè)因果和例子來繼續(xù)發(fā)展。請(qǐng)注意，個(gè)原因后的那個(gè)句子是解釋貪婪的原因，屬于因果法;而第二個(gè)原因后作者是通過舉例的方式來進(jìn)一步論述。
