2026年新高考Ⅰ卷 阅读理解C篇说题 1 倒装 考点精讲二 2026年全国一卷阅读理解C篇 In line with longstanding initiatives to expand its green spaces, New York City is planting tens of thousands of trees each year. They provide shade, lower surface temperatures, absorb a surprising amount of airborne carbon, remove tiny pollutants, and provide wildlife habitat along with just plain beauty. Something could go wrong, though, according to a new study. Oaks and sweetgums, which currently account for a majority of the city’s trees, produce huge amounts of a chemical substance called isoprene. Harmless by itself, isoprene interacts rapidly with polluting nitrogen oxides released by vehicles, buildings and industry to form ground-level ozone (臭氧) — a major factor in many breathing problems. The research, carried out by scientists at the Columbia Climate School and other institutions, found that if the city maintains past species patterns in new plantings, isoprene production in Manhattan in coming decades will go up by about 140%, and resulting summer ozone levels as much as 30%. “We’re all for planting more trees. They bring so many good things,” said study coauthor Róisín Commane. “But if we’re not careful, we could make air quality worse.” The Parks Department is not oblivious to the issue. A study carried out by some of its researchers several years ago concluded that city trees did release isoprene. “We didn’t make a big deal of that,” said Novem Auyeung, a Parks Department senior scientist. She said trees should not be viewed as the enemy. “We could plant any trees we want to, if we just rethink our car-centric lifestyle,” she said. 原题呈现 倒装 考点精讲二 “We’re not going to go cutting down any big old oaks,” and neither will the department completely stop planting new ones, said Auyeung. “You have to think about what you would lose if you do that.” Oaks are keystone species, she pointed out, providing food and habitat for native insects, birds and other animals. 原题呈现 28. What does the new study imply regarding oaks and sweetgums? A. They affect the growth of other trees. B. They absorb less carbon than expected. C. They harm people's health indirectly. D. They raise the local temperature slowly. 29. Which of the following may Commane suggest based on their study? A. Cutting down the isoprene-producing trees. B. Suspending tree-planting for a few decades. C. Changing the species of trees in new plantings. D. Removing isoprene released by existing trees. 30. What does the underlined phrase “oblivious to” in paragraph 5 mean? A. Honest about B. Unaware of C. Related to D. Optimistic about 31. What would Auyeung probably advocate? A. Reducing car use in daily life. B. Providing animals with new habitats. C. Controlling population growth. D. Doing more research on the problem. 语篇分析 ·文章来源：哥伦比亚大学气候学院官网(Lamont-Doherty地球观测站)—Planting Some Tree Species May Worsen, Not Improve, NYC Air · 主题：人与自然（生态）—— 城市绿化树木释放的化学物质与汽车尾气结合后加剧臭氧污染，可能影响身体健康。 · 语篇类型：说明文——反常识的环保科普 · 素养：跨学科思维、辩证思维、科学探究精神 · 教材关联：人教：必修2 Unit2、必修1 Unit4（环保、灾害） 图示：城市雾霾笼罩下的空气污染物聚集，植物排放的挥发性有机物会与这些污染物发生光化学反应，加剧臭氧污染。 语篇结构 part 1:背景引入（第1段） •政策初衷：纽约市长期推行植树计划以扩大绿地面积。 •树木益处：列举了树木在遮阴、降温、吸收碳、清除污染物以及提供野生动物栖息地等方面的积极作用。 part 2:揭示问题与科学解释（第2段） •潜在隐患：新研究指出，占多数的橡树和枫香树会释放大量名为“异戊二烯”的化学物质。 •污染机制：该物质本身无害，但会迅速与车辆、建筑和工业排放的氮氧化物反应，生成引发呼吸系统疾病的地面臭氧。 part 3:研究数据与专家观点（第3–4段） •预测数据：若维持现有树种模式，未来几十年曼哈顿的异戊二烯排放量将增加约140%，夏季臭氧浓度最高增幅可达30%。 •专家态度：研究人员支持植树，但强调如果不谨慎考虑的话，可能会导致空气质量恶化。 part 4:官方回应与辩证思考（第5–6段） •官方认知：公园局认为树木不应被视为“敌人”，解决空气污染的关键在于反思和改变“以汽车为中心的生活方式”。 •政策底线：官方不会砍伐老橡树，也不会停止种植新树，因为橡树作为“关键物种”在维持生物多样性和提供栖息地方面具有不可替代的价值。 解题分析 28. What does the new study imply regarding oaks and sweetgums? A. They affect the growth of other trees. B. They absorb less carbon than expected. C. They harm people’s health indirectly. D. They raise the local temperature slowly. 细节理解题 定位文章第二段，聚焦橡树与枫香树的化学物质排放。 “Oaks and sweetgums, which currently account for a majority of the city’s trees, produce huge amounts of a chemical substance called isoprene. Harmless by itself, isoprene interacts rapidly with polluting nitrogen oxides released by vehicles, buildings and industry to form ground-level ozone (臭氧) — a major factor in many breathing problems.” 解题分析 29. Which of the following may Commane suggest based on their study? A.Cutting down the isoprene-producing trees. B. Suspending tree-planting for a few decades. C. Changing the species of trees in new plantings. D. Removing isoprene released by existing trees. 推理判断题：研究团队的核心建议，定位第三、四段。 根据第三段 “The research, carried out by scientists at the Columbia Climate School and other institutions, found that if the city maintains past species patterns in new plantings, isoprene production in Manhattan in coming decades will go up by about 140%, and resulting summer ozone levels as much as 30%.” 再结合第四段“We’re all for planting more trees. They bring so many good things,” said study coauthor Róisín Commane. “But if we’re not careful, we could make air quality worse.” 解题分析 30. What does the underlined phrase “oblivious to” in paragraph 5 mean? A. Honest about. 坦诚面对 B. Unaware of. 未意识到 C. Related to. 与之相关 D. Optimistic about. 保持乐观 词义猜测题：定位原文第五段首句：“The Parks Department is not oblivious to the issue.” 后文 A study carried out by some of its researchers several years ago concluded that city trees did release isoprene. 指出该部门研究人员“几年前已做过相关研究并得出结论”，这直接证明了部门对问题是“知情的”。因此，“not oblivious to” 即“并非不知道”，双重否定，反向推断出 “oblivious to” 意为“未察觉、不知道的”。 解题分析 31. What would Auyeung probably advocate? A. Reducing car use in daily life. B. Providing animals with new habitats. C. Controlling population growth. D. Doing more research on the problem. 专家观点辨析题：Auyeung 的倡导方向 根据第五段 She said trees should not be viewed as the enemy. “We could plant any trees we want to, if we just rethink our car-centric lifestyle.” 文中 Auyeung 强调树木不应被当作环境问题的“替罪羊”，这直接指出了城市生态问题的核心症结在于汽车的过度使用。汽车是氮氧化物的主要排放源，因此减少汽车使用是Auyeung最可能倡导的解决方案。故选A. 语言知识 重点单词： longstanding adj. 存在已久的 initiative n. 倡议 carbon n. 碳 shade n.树荫，阴凉处 v.遮蔽 airborne adj.空气中传播的，空气传播的 pollutant n.污染物 currently adv.目前 volatile adj.挥发性的；易变的 compound n.化合物；复合物 emit v.排放，散发；emission n.排放 asthma n.哮喘 significantly adv.显著地，大幅度地 dwellers n.居民（尤指城市居民） oblivious adj.未察觉的，遗忘的 proportion n.比例，份额 keystone n.关键，基石 function v.起作用，运转 n.功能补充写作 fossil fuels 化石燃料 重点词块： in line with 与...一致 along with 连同，以及 make a big deal of 小题大做，过分看重 熟词生义 plain beauty 纯粹的美丽 熟词生义 be to blame 应受指责 car-centric lifestyle 以汽车为主的生活方式 in favor of 支持；取代 一核：立德树人 · 价值引领 文章以城市绿化为切入点，探讨生态与发展的辩证关系，引导学生树立“人与自然和谐共生”的生态价值观，培养用批判性思维解决问题的能力，培养观察与科学探究能力。 命题立意 01 核心价值：关注现实与责任 紧扣时代脉搏，引导学生关注全球环境议题，培养社会责任感、家国情怀与人类命运共同体意识，树立正确的生态观与发展观。 02 学科素养：综合能力与视野 全面考查语言解码与逻辑梳理；要求学生具备跨学科视角，提升逻辑推理与辩证思维品质。 03 关键能力：信息处理与分析 侧重科学原理、不同人物立场辨析，长难句处高频设题，注重高阶思维的运用。 04 必备知识：语言基础与逻辑 涵盖考纲核心词汇、短语搭配、熟词生义及复合句等语法知识；同时考查对说明文的语篇解构和逻辑理解。 11 命题趋势 1、 话题选择 · 强化跨学科视野 聚焦环保类生态议题这一全球性热点，紧贴现实生活与时代发展趋势，强化从跨学科视角辨析实际问题，体现语言学习的实用性与时代感。 3、 素养导向·持续落实立德树人 从事实细节的浅层获取，转向深层逻辑推理、人物立场判断及文章结构脉络和逻辑关联的分析，强化逻辑思辨能力，强化对独立思考、质疑与批判能力的检验。 2、 立足课标·强化基础语境化考查 侧重考查熟词生义、派生词及语境词义推断，弱化孤立记忆，考生需建立“语篇-语境-词汇-语法”一体化学习思维。 教学启示 1、精选外刊语料，关注社会热点 多选取外刊比如《经济学人》《纽约时报》的文章，以及名校官网科研新闻（剑桥、哥大）等相关的真实语料，让学生接触鲜活且地道的语言表达，在拓宽视野的同时，提升对不同题材的适应能力。 4、加强词汇与语法的语境化教学 积累熟词生义，依托真实语篇和长难句分析，让词汇和语法知识回归语境。通过在具体语境中理解、记忆和运用，实现语言知识的内化与灵活迁移。 2、强化语篇分析能力 系统训练学生拆解文章的体裁特征、段落结构与逻辑关系，引导其精准捕捉人物的隐含观点、情感态度及作者的写作意图，构建宏观的文本分析框架。 3、注重深层理解与逻辑推理训练 设计需要归纳总结、推断延伸的高阶思维练习，鼓励学生跳出表层信息，培养批判性思维，提升对复杂文本的深层解读与逻辑推理能力。 13 THANKS! 14 $
