健康环保类阅读

健康环保累阅读概念：

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、说明文、议论文和各种应用文。

健康环保类文章阅读技巧：

       健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
       第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
       第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
       第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
       从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
【阅读策略】
1、概要(Summarizing)：
      阅完材料后，将所阅材料浓缩，摘要，做出所阅材料的书面或口头梗概。
2、组织(Organization)：
      阅读后根据阅读内容，识别观点、人物、事件之间的关系以及文章的结构关系。如：时间关系、比较或对比关系、相关关系及因果关系等。
