2021年新高考英语重难点练03

阅读理解之说明文

【命题趋势】

阅读理解说明文，是对事物或事理进行客观说明的一种文体，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。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，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，同位语、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。

【应试策略】

阅读理解说明文的设问主要主要以细节事实、主旨大意和猜测词义三方面问题为主。

一、词义猜测类题型

词义的猜测贯穿在文章的阅读理解之中。解这类题目一般是通过上下文去理解或根据构词法去猜测。判断

一个单词的意思不但离不开句子，而且还需要把句子放在上下文中，根据上下文提供的线索加以猜测。运

用构词法，语境等推测关键词义。

二、主旨大意类题型

主旨大意类题型主要测试学生对文章全面理解和概括的能力，提问的内容可能是全文的大意，也可能是某

段的段落大意，一般不易在文中直接找到答案。怎样把握主旨大意题呢？通常有以下几种方法：

可以通过阅读文章的标题或副标题、寻找文章的主题句或高频词。
