在闡述某一現象的段落中，常采用因果分析法。例如：

　　The role of women in todays society is changing. One reason is that women have begun to assert themselves as independent people through the womens movement. Also, women are aware of the alternatives to staying at home. Another reason is that increasing numbers of women who enter new fields and interests serve as role models for other women. Moreover, men are becoming more conscious of the abilities of women and have begun to view their independence positively.

　　本段中，主題句提出了一種社會現象，推展句則對產生這種現象的原因作出各種解釋。 常用于因果分析法的連接詞有：because, so, as a result等。
