12、一般是首先提出一个要说明的对象，如某种理论、某种方法、某种技巧、某项活动，然后按照时间、空间、事情发展顺序，运用列举、对比、演绎、归纳等方式进行介绍和说明。说明文型完形填空常就某一个问题从不同的角度来加以说明。文章还可以用来说明某一个存在的社会现象、一个产品的制作过程、一个产品的使用方法、某个科学成就或人类生活中所面临的某个具体的难题。对于这一类型的完形填空，对考生而言最重要的还是要抓住作者说明的中心。说明文所呈现的方式往往比较单一，作者往往一开始就交代说明的对象，然后再从不同的角度进行说明。由于以上特点，这类文章的每一段往往就是其中的一个角度或侧面。因此，考生要注意概括每一个段落的主旨大意。
