1、考点33阅读理解说明文(重难题型)说明文是对事物或事理进行客观说明的一种文体，它以说明为主要表达方式，通过解说事物或阐明事 理，达到教人以知识的目的，在结构上往往采用总分、递进等方式按一定的顺序(如时间、空间、从现象 到本质)进行说明。说明文的特点是客观、简练、语言准确、明了，文章很少表达作者的感情倾向。阅读 说明文的重点在于读懂它说明的事物或事理，了解事物的性质、构造、成因、功能等，了解事理的含意、 特点等。最近五年，说明文的出现变化不大，一直很稳定，选材通常是各学科的前沿问题；高科技领域的 科研成果；人们比较关心的社会问题；人文方面的经典。由于阅读理解题的设置采用渐进式，即由简到难 的方式

2、，因此说明文是高考试卷中阅读理解题中相对比较难的，通常后置。阅读理解试题的中要考点之一 是考查学生对词汇和句式的掌握。说明文的词汇和句式的运用较别的体裁的文章难度更大。词汇运用灵活, 同一词的不同词性的用法交替出现，未列入考纲的生词较多，通常达到了 4-5%o不过考生可以通过说明 文的语言特点来帮助理解语篇，例如，下定义、解释、举例、同义词、反义词、上下义词以及标点符号(如 破折号、冒号都有表示解释和说明)等。命题方式考向一细节理解题说明文中考查的细节理解题大致与记叙文相似。命题区域都有其共同点：在列举处命题，如用 first(ly) second(ly) third(ly)finally n

3、ot onlybut also then、in addition 等表示顺承关系的词语列举出事 实。试题要求考生从列举出的内容中选出符合题干要求的答案项。在例证处命题，句中常用由as、such as、 for example for instance等引导的短语或句子作为例证，这些例句或比喻就成为命题者设问的焦点。在 转折对比处命题，一般通过however、but、yet、in fact等词语来引导。对比用unlike until、not so much.as 等词语引导，命题者常对用来对比的双方属性进行考查。在比较处命题，无端的比较、相反的比较、偷 换对象的比较，经常出现在干扰项札 考生要标

4、记并且关注到原文中的比较，才能顺利地排除干扰。在 复杂句中命题，包括同位词、插入语、定语、从句、不定式等，命题者主要考查考生对句子之间的指代关 系和语法关系。细节类问题一般都能在原文中找到出处，只要仔细就可以在文中找到答案。但正确的选择项不可能与阅 读材料的原文完全相同，而是用不同的语句成句型表达相同的意思。考向二语意猜测题说明文为了把自然规律，事物的性质等介绍清楚或把事理阐述明白，因此学术性强的生词较多，所以常 进行生词词义判断题的考查。命题方式多以the underlined part .in paragraph. refers to.或 what does the underlined

5、word mean?或 what is the meaning of the underlined word?为设问方式。解题时考生应 认真阅读原文，分析其对某些科学原理是如何定义、如何解释的，并以此为突破口抽象概括出生词词义。 也可以通过上下文来猜测某个陌生词语的语意。或者找出某个词语在文章中的同义词。要注意破折号、同 位语从句、定语从句、插入语等具有解释、说明作用的语言成分。说明文在阐述说明对象时易发生动作变 换、人称转变的现象，这类题目常以it, they, them等代词为命题点，因此考生要根据上下文语境，认真 阅读原文，分析动作转换背景，弄清动作不同执行者，以便准确判断代词的其实际指

Native Americans have taken care of these precious natural resourses wisely. Unfortunately, it took
