完形填空（说明文）--解题技巧及典例剖析1.文章多用现在时态说明文通常是对客观事物或实例的介绍与说明，与时间的变化关系不大，所以文章常用现在时态。

2.语言简练、平实、准确，常采用客观描述说明文的目的主要是帮助读者认清事物，明白事理，所以语言简练、平实、易于理解，内容客观真实，很少含有带感情的词汇。

3.文章主题明确，层次分明说明文类完形填空往往在文章开头就点明说明对象，从而为学生们把握文章主题提供了有利条件。

而且，1.利用说明文首句，明确说明对象典例1(2015·重庆高考B)Imagine the first days in a new time zone . Slow to respond to the 28______ , your body clock is confused.
