2024年高考英语二轮复习06 阅读理解之说明文（原卷版+解析版）

06 阅读理解之说明文 说明文的特征及相关试题应对分析 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，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%。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。 一、说明文的行文特征 写说明文可以按时间、空间、结构、逻辑顺序来写，也可以采取举例、比较、对比、分类、分析、说明、叙述等方法。 1.比较对照 比较对照有两种，一是逐点比较，二是整块比较，即AB交错或先A后B： （1）逐点比较 多数人认为这种AB交错的方式可以避免行文的单调沉闷，对比的效果更鲜明突出。如： There are basic differences between large and small enterprises. In a small enterprise, you operated mainly through personal contacts. In a large enterprise, you have established “policies” , “channels” of organization, and fairly strict procedure. In the small enterprise you have immediate effectiveness in a very small area. You can see the effect of your work and of your decisions ground. In the large organization you are normally taught one thing thoroughly. In the small one the danger is of becoming a Jack-of-all-trades-but-master-of-none. In the large it is of becoming the man who knows more and more about less and less. （2） 整块比较 It is easy to be a winner. A winner can show his joy publicly. He can laugh and sing and dance and celebrate his victory. People love to be with winners. Winners are never lonely. Unlike winners, losers are the lonely ones of the world. It is difficult to face defeat with dignity. Losers can not show their disappointment publicly. They can not cry or grieve about their defeat. They may suffer privately, but they must be composed in public. They have nothing to celebrate and no one to share their sadness. 2.分类 分类是人类认识客观世界的重要手段之一，也是描写事物、解释观点最有效的方式之一。通过将一事物分类，可使复杂事物变得清晰明了，便于作者阐述自己的观点。 分类段落的各类排列要条理，可采用从主要到次要，从次要到主要，从多到少或从少到多等方式排列，亦可平行排列。如： [1]As far as political views are concerned, people fall into three categories. First are the conservative people. Conservatives are opposed to sudden or great changes. Second are the liberal people.These people are in favor of progress and reform. But their opinions often se ... ...
