第七单元 如何写好一个段落（Ⅱ）

7．1连贯性

段落的连贯性指的是段落的句子以清晰、符合逻辑的顺序（clear， logical sequence）连接。连贯性使读者能够找出每个观点之间的联系以及这些观点与主题句的联系。

7．2关于如何取得连贯性的建议

1）使用同一时态

如果随意而毫无理由地改变时态（tenses），那么不管作者连句的技巧多么高超，段落也不可能取得连贯性。在写作时，可以使用现在时（ present tense）或过去时（past tense）。选用哪一种取决于作者处理材料的方式。

2）使用某种逻辑顺序

常用的逻辑顺序有： 1）时间顺序（time order）； 2）空间顺序（space order）（见第12单元）； 3）重要性顺序（order of importance）和 4）熟悉度顺序（order of familiarity）（见第 19单元）。

3）使用连接成分

使用某些连接词和短语（connective word Sand phrases），重复某些关键词（repetition of certain key words），可以大大增加段落的连贯性。某些连接词、短语和关键词可以起粘着物（adhesives）的作用，把各部分连接起来，使句子间的关系更加清楚。连接成分主要有以下三种：

a．连接词语（linking expressions）（见第34单元）

b．代词（pronouns）

代词用于提醒读者注意其先行词，以此把有关的部分连接起来。

c．重复关键词语（repetition of key words）
