完形填空基本解题策略

1.宏观上把握文章的中心和结构

考研英语完形填空的文章以说明文和议论文为主，个别情况下会出现夹叙夹议的文章。它们一般具有以下两个特点：

1)都有明确的中心

由于完形填空要求从内容和结构两个方面将文章补充完整，整篇文章一般只有一个中心意思，而且具有逻辑性和完整性。从文章的篇章结构来看，第一句话一般都是主题句。为了帮助考生进入语境和答题状态，出题者往往先提供一个完整的句子，设置题目从第二句开始。

2) 往往采用总分结构

通过大量的总结分析，可以发现考研英语完形填空的文章在结构上经常采用总分对照的形式，这就为我们迅速从整体上把握一篇完形填空提供了非常便利的条件。

明确了以上两点就为完形填空的解题从宏观上指明了方向，下面以2004年的真题为例，讲解如何把握文章中心和结构。
