14、、说明的一种文体。与记叙文相比，说明文类完形填空有如下命题特点：1文章多用一般现在时态。 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，所以文章常用一般现在时态。2语言简练、平实、准确，常采用客观描述。 说明文的目的是要帮助读者认清事物，明白事理，所以语言简练、平实，易于理解，内容客观真实。3文章主题明确，层次分明。 高考说明文类完形填空往往在文章的开头就点明说明对象，从而为同学们把握文章主题提供了有利条件。 而且，作者借助合理的说明顺序展开文章，使文章结构清晰，层次分明。二、解题技巧1明确说明对象，理清段落关系。 通读全文，明确作者是针对哪一个说明对象从不同的角度和侧面对其
15、加以说明的。 在阅读过程中要概括、总结每一段说明的侧重点，理清各段之间的关系，加深对说明对象的理解。2弄清说明顺序，把握作者态度。 在说明的过程中作者会选择合理的说明顺序对说明对象进行解说。 把握了说明顺序就能准确把握文章的脉络，加深对整篇文章的理解。 常见的说明顺序有时间顺序、空间顺序、逻辑顺序(如因果关系、果因关系、先主后次等)和认识顺序(如由此及彼、由浅入深、由局部到整体、由现象到本质等)。 另外，在理清作者思路的基础上，还要注意反映作者态度的关键词或关键句，把握作者的写作情感和意思。(2018河北衡水中学一调)Do you ever feel like you are studying
