科普类阅读答题方法

【题型说明】科普知识类文章在高考试卷中是倍受青睐的又一宠儿。每年高考都有关于科普知识类阅读理解材料的考查。这类文章的特点是科技词汇多，句子长且结构复杂，理论性和逻辑性又都较强，再加之文章所介绍的知识对于同学们来说是比较陌生的。因此，同学们看这类文章觉得是雾里看花。 【文章特点】科普类文章的主要特点：

1. 文章中词汇的意义比较单一、稳定、简明，不带感情色彩，具有单一性和准确性的特点。综观整篇文章可以明显看出，它没有文学英语中常采用的排比、比喻、夸张等修饰手段，一词多义的现象也不多见。

2. 句子结构较复杂，语法分析较困难。为了描述一个客观事物，严密地表达自己的思想，作者经常会使用集多种语法现象与一体的长句。 3. 常使用被动语态，强调动作的承受者。 4. 常使用双重否定句。

【结构特点】科普知识类文章结构一般也是由标题(Headlines),导语(Introductions)，背景( Background)，主体(Main body)和结尾(Ends)五部分构成。标题是文章中心思想高度而又精辟的概括，高考这类阅读理解材料一般也不给标题，而要同学们选择标题。导语一般位于整篇文章的首段。背景交待一个事实的起因。主体则对导语概括的事实进行详细叙述。这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点。结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题。

【备考提醒】要做好这类阅读理解题，先要掌握这类文章的特点和结构，真正读懂并理解它。其次，工夫在课外，平时一定要多读科技幻想类文章，比如：太空与海洋、创造与发明、计算机发展、人类未来、动物世界等。特别是从网上搜寻一些取材原版、内容时新、语言鲜活的科技幻想类材料阅读。这样长期坚持，既可以增长知识、开阔视野，又可以扩充科技词汇，还能提高解答这种类型试题的能力。我们何乐而不为呢？。
