19．1 重要性顺序排列法
前面我们已经讨论了组织段落的两种方法--时间顺序法（time-order）和空间顺序法（space-order）。组织段落的第三种方法是根据重要性排列的方法（to organize details according to their order of importance）。作者使用这种方法的依据是他认为所选用的细节应如何加以强调。
使用重要性顺序法，可选用上升顺序（ascending order），或下降顺序（aescending oraer）。前者先列举次要观点，把重要的留到最末（如示范段落17-1），后者先强调最重要的观点，然后列举次要观点（如示范段落4-1）。
19．2 熟悉度顺序排列法
对于某些段落，也许使用熟悉度顺序法（order of familiarity）更恰当。这种方法根据读者对作者所选用的一系列细节的熟悉程度排列。例如，在分类段落中，作者经常先谈论读者比较熟悉的、具体的细节，然后谈论读者不大熟悉的细节，如示范段落16-1。
19．3 使用顺序法的一般准则
到目前为止，我们共讨论了四种组织段落顺序，使用哪一种顺序取决于作者的写作目的和读者对主题的熟悉程度。
1）如果你要说服别人相信一个观点，应该选用重要性顺序，把最好和最有力的理由放在能使读者最容易牢记的地方--段末。
2）如果你要向读者准确地展示一个场面，则应选用空间顺序描述，以便你的读者能够在脑海中再现你所描绘的画面。
3）如果读者对你要谈论的话题不大熟悉，则应从熟悉的观点着手。
4）如果你要告诉读者发生了什么事情或怎样做某件事，则需要时间顺序。
