焦点03阅读理解之说明文备考2026年中考英语新课标（核心素养）同步大师课堂之题型特训面面到【题型解析】考查方向具体说明考查位置通常在阅读理解部分占据重要篇幅，例如根据2025年河南中考英语试题分析，C篇多为说明文分值题量通常为5道小题，每小题2分，共计10分文本特点题材广泛，可能涉及科学技术、生态环境、文化习俗、社会现象等。语言客观、准确，逻辑清晰，可能包含数据、实例或专业术语。核心能力考查信息定位、细节理解、逻辑推理、词义猜测以及归纳主旨的能力一、考查重点与题型解析说明文阅读的考查点非常明确，主要集中在以下几个方面：细节理解题（基础与核心）：这是最主要的题型，占比很高。题目主要考查对文中具体事实和信息的捕捉能力，如数据、步骤、特征等。解题关键在于精准定位，答案通常直接来源于文章中的某句话，但要小心选项常会进行同义转换。推理判断题（理解与思维）：这类题目需要你根据文章已给信息，进行一步的逻辑推断。比如推断事件的因果关系、作者的倾向或事物的未来发展。解答时务必以文本为依据，避免主观臆断。词义猜测题（语境与技巧）：说明文中可能出现少量生词或专业术语。题目要求你根据上下文线索（如同义词、反义词、定义或举例）来推测其含义。主旨大意题（综合与概括）：考查对整篇文章或段落中心思想的把握能力。要特别关注文章的标题、首段和尾段，以及每段的开头句和结尾句，这些地方往往是主题句所在。二、高分解题步骤遵循科学的解题步骤可以有效提高准确率：快速浏览，抓住主旨：用几十秒快速阅读文章的标题、首尾段以及每段的首句，迅速把握文章主要说明的对象和基本结构。审读题干，定位关键：仔细阅读问题，圈出关键词（如人名、地名、核心概念、数字等）。然后带着这些关键词回到原文中进行扫读，找到相关信息所在的句子或段落。分析对比，确定答案：仔细比对原文信息与选项的差异。对于细节题，直接比对；对于推理和主旨题，则需在理解相关段落或全文的基础上进行归纳和判断。复核检查：完成所有题目后，将答案代入全文通读一遍，检查是否顺畅合理，确保答案有据可依。三、高效备考策略拓宽阅读面：平时有意识地多阅读一些科普文章、社会文化介绍等说明性英文短文，积累不同话题的词汇和背景知识。掌握文章结构：注意学习说明文常用的方法，如下定义、举例子、作比较、分类别等，这有助于理清文章逻辑。精练真题，限时模拟：使用河南中考历年真题和高质量模拟题进行专项训练。练习时注意限时，一般一篇说明文阅读的完成时间建议控制在810分钟。做完后务必分析错题，弄清错误原因。关注趋势：近年来中考英语阅读更注重与现实生活和社会热点的结合，以及中华优秀传统文化的融入AHaveyoueverwonderedwhyyourparentsmakeyoueatyourvegetables?Doyourememberhowterribletheytasted,butyourparentsseemedtoenjoythem?Doyouthinkyourparentslovedvegetableswhentheywerechildren?Well,theyprobablydidn’t!So,whathappened?Thetruthisthatourtastebuds(味蕾)canchangeovertime.Aswegrowolder,tastebudsstartdisappearing.Thatcanmakesometastesfeelweaker,butitmightalsohelpuslikenewfoods.Didyouknowthatanadult(成年人)usuallyhasbetween2,000and10,000tastebuds?Themoreyouhave,themoretastesyoucanenjoy.Youngchildrenwithgrowingtastebudsmayhaveastrongersenseoftastethanadults.Thatexplainswhysomechildrenmightnotlikebroccoli(西兰花)nowbutcouldloveitwhentheygrowup.Ofcourse,howfoodtastesisn’tjustabouttastebuds—thesmellmattersalot,too.Iffoodsmellsstrong,itmightturnchildrenaway,eveniftheydon’tmindthetaste.Thegoodnewsisthatyoucanlearntolikenewfoods.Sometimes,addingsomethingyoulove,likecheese,canmakeabigdifference.Finally,youcanetodislikecertainfoodsyouonceloved.Ifyoueattoomuchicecreamandthengetsick,youmightnotwanttoeatitforalongtime.Thisdislikecanstickaroundforyears!Yourtasteinfoodcanchangeinsurprisingways.So,evenifyou’renotexcitedaboutthosevegetablestoday,rememberthatyourbodywillthankyoulater.Oneday,youmightevenenjoythem!1．Whatdoestheunderlinedword“them”inParagraph1referto?A．Foods.
