21.2 段落与篇章的结构
根据所给范例，我们可以看到段落的结构很简单，它主要是由三部分组成的：
1）主题句（topic
sentence）：引出全段的主题思想。
2）几个支撑句（supporting
sentences）：说明或铺叙该段落的主题思想。
3）结尾句（concluding
sentence）：总结段落的主旨。
由此，范例段落的结构可表达为：ts/s1，s2，s3，s4/c=
1/2，3，4，5/6。
ts：主题句
s：支撑句
c：结尾句
同样，段落的组成结构ts/s1，s2，s3，s4/c又可以说是篇章结构的扩展，篇章也由三部分组成：
1）主题段（topic
paragraph）：引出并点明支配全篇文章的主题，指出主题所包含的几个方面，确定推展段的内容和形式。
2）支撑段（supporting
paragraphs）：由若干段落组成，对主题段所引出的主题展开讨论。其直接作用是支持各段的主题句，间接作用是辅助各段的主题句支持主题段中的主题思想。
3）结尾段（concluding
paragraph）：对全文归纳总结。一般可采用以下四种方式对全文进行归纳：a.简明归纳全文；b.回顾主题，使首尾呼应；c.变化措词，重申主题；d、提出问题，启发思考。
21.3 model paragraph 21-1.和model essay
21-2.的分析
由此可以看出段落范例中的主题句已扩展成为篇章中的主题段；支撑句s1发展为第一支撑段的主题句；支撑句s2成为第二支撑段的主题句……；范例段中的结尾句则成了结尾段的主题句。

第二十二单元 篇章的统一性、支撑性、连贯性和一致性
22.1 篇章的统一性（unity of an essay）
篇章的统一性是指各推展段落都必须紧扣主题思想，不包含与主题思想无关的任何部分。如果包含与主题思想无关的部分或出现多层意思，就会导致主旨不清，思路混乱。
22.2 篇章的支撑性（support of an essay）
只有通过具体的实例、事实、细节或事件对篇章中的主题思想加以充实和发挥，才能使文章的主题更加明确具体。例如：在unit 21-2范文中的四个supporting paragraphs（sp1，sp2，sp3，sp4）都是通过具体的实例、细节，来进一步明确本篇文章的主题思想—to be successful in a job interview，you must demonstrate cetain personal and professional qualities.
22.3 篇章的连贯性（coherence of an essay）
篇章的连贯性是指句子与句子，段落与段落的排列组合必须合乎逻辑（意连）；句子间以及段落间的过渡必须自然流畅（形连）。篇章的意连有三种：a.time order or
chronological order（时间顺序）；b.space or
spatial order（位置或空间顺序）；c.logical order（逻辑顺序）。其中，逻辑顺序又可分为三种：
1）order of
importance（重要性顺序）
2）specific-to-general（从具体到总论）
3）general-to-spacific（从总论到具体）
例如，在unit 21中的model essay中，作者就是以general-to-specific的逻辑顺序来推展文章主题的。作者先是给出一个topic sentence，然后通过四个具体的“you should……”对主题加以支撑、充实，从而达到了意连。
而转换此词语（transitions）则是篇章形连的重要手段。
unit 21中的model essay也正是通过许许多多的转换词语使文章达到了自然流畅。以下让我们就此范文的首段（tp）和第一支撑段（sp1）为例，来看看转换词语承上启下之作用。

22.4 篇章的一致性（sentence skills in an essay）
若要读者完全、正确地领会我们所要表达的思想内容，在写作篇章时，我们必须简洁明白，写出合乎语法规范的句子，正确的语法包括（nouns；pronouns；verb tenses；fragments（不完整的句子）；dangling modifiers（垂悬修饰语）；run-ons（用错逗号的句子或乱加从句的冗长句子），etc.
