合理的段落展開方法能把中心思想和材料有機地組織起來，讓讀者在閱讀過程中感到很強的條理性。下面主要介紹四種英文段落的擴展方法：
比較與對比法
比較(comparison)是分析不同的人、物、地點或觀點之間的相同之處，對比(contrast)是分析它們之間的差異。例如Reading Selectively or Extensively? (1999.6 CET-4 & CET-6 )一文的第2 - 3段就對比了讀書要有選擇和博覽群書這兩種觀點和看法：
Some people say that we should read selectively. They believe that it is not how much one reads but what he reads that really counts....
However, others claim that reading extensively is a better choice. In their opinions, different books are of different uses....
再如 My View on Job-Hopping (1997.6 & CET-6)一文的第1 - 2段也采用了對比法，比較了喜歡從事一種工作和喜歡經(jīng)常更換工作這兩種人的觀點：
Some people tend to stick to their jobs all their lives. For example, some have been teachers all their lives, and some devote all their energies to scientific research that they like. In their views, the longer one works in a particular field....
On the contrary, others would like to change jobs constantly.... For them, there is no better than to meet more people, make more money and get more experience, so they often change their jobs.
