考点30 阅读理解之说明文-备战2023年中考英语一轮复习考点帮（全国通用）

考点30 阅读理解之说明文 ＂英语说明文＂，顾名思义，就是一种以＂说明、解释＂为主要表达方式的英语文体。它是对客观事物的性状、特点、功能和用途等作科学解说的。它既不像故事那样重在情节的叙述和描写，也不像议论文那样，重在阐明主张和论点论据；更不像科幻作品那样富于想象和虚构夸张。说明文是通过解说事物、阐明事理，使人们增长知识和技能。说明文是高考英语阅读理解题中的重点内容之一。说明文具有与自己特点相适应的说明方法，因此说明文结构复杂，专业术语多，易于拉开考生分数档次，便于高校分层次选拔人才。然而对于考生来说说明文抽象度高，解题难度大。高考对说明文的考查多为科普知识，动植物特性、自然现象和新产品、新工艺介绍以及人文地理、风土人情等方面的说明文，文中解释性、定义性、说明性的句子居多。因此考生要掌握说明文的命题特点，叙述方式，以冷静的心态阅读原文，重点突破长句结构特点和逻辑关系，以便对其做出准确的语意理解。 说明文阅读理解的特征 一般说来，英语说明文与其他文体一样，文章所涉及的内容不外乎以下几个方面，即who → what → when → where → how → why。 1. who：问的是这篇文章的主体是谁？（即所要说明和描述的人或事物） 2. what：问的是主体做了什么事情？（即主体表现出的特性、功能和用途） 3. when和where：是在何时何地发生的？（即何时何地所表现出的特性、功能和用途） 4. how：通过什么方式表现出来的？ 5. why：这种特性功能用途的原因是什么？ 做说明文阅读理解题的时候，一定要记住上面的wh-word。边阅读，边搜记，牢记要点，把握全文。 Passage1 Schools in China are studying how they can put VR (=virtual reality虚拟现实) lessons into their classroom experience. One such lesson uses VR to teach children fire safety. Instead of pens and paper, students wear VR headsets in the classroom. They are put into a virtual environment where a fire has broken out. They must find their way out and escape carefully. At the VR medical school under Sichuan University, a virtual system allows medical students to examine human body in different ways. They can even separate the body for closer examination. Students can practice their operation skills without a real body. Simon Leung, vice-chairman of a VR company, said the company has developed VR classrooms and computers that send students to a 360 degree digital world. Moreover, the VR headsets can tell whether children are focused on the task at hand, Leung said. Chinese parents, however, have a different opinion on VR lessons. They are suspicious of VR because they are unsure if the technology will have any bad effects. They are worried about their children’s eye sight, too. Besides, VR equipment comes at a high price. A top VR headset and computer could cost up to 10,000 yuan(1,475 U. S. dollars). “We need to do more to lower
