第二十單元 推展段落方法——混合方法

20．1 混合方法（Mixed Patterns）

到目前為止，我們討論了九種推展段落方法——1）事實數據法（facts and statistics）；2）敘述法（narration）；3）描述法（description）；4）過程分析法（process analysis）；5）定義法（definition）；6）舉例法（examples）；7）比較對比法（comparison and contrast）；8）分類法（division and classification）；9）因果法（cause and effect）。我們還討論了四種組織段落的方法：1）時間順序法（time order）；2）空間順序法（space order）；3）重要性順序法（order of importance）；4）熟悉度順序法（order of familiarity）。此外，我們還談及一個好的段落的三個特征：1）完整性（completeness）；2）統(tǒng)一性（unity）；3）連貫性（coherence）。

我們在前面各單元的示范段落中已經發(fā)現(xiàn)，極少段落是僅用一種推展方法的。作者常常在段落中使用一種方法作為支配方法（dominant method），另外一種或數種作為輔助方法（supporting method）。
