重难点练03 阅读理解之说明文 - 2021新高考英语【热点·重点·难点】专练（山东专用）

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%。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。 《真题再现》 Passsage 1 【2020·全国新高考II山东卷】 According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid. To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds. Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin. For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the part
