生态环境、国土安全（课标新增主题专练）-2026年高考英语二轮复习解析版

专题05生态环境、国土安全

I|主I题I简I介|

；2025年高中英语课程标准新增“生态环境”与“国土安全”两大主题，此举深刻体现了教育对国家战

；略与全球性议题的积极响应，标志着英语教学从语言工具性向育人价值的深化。“生态环境”主题的引入,

:直面气候变化、生物多样性保护等全球性挑战，与我国“双碳”目标和“生态文明建设”的国家战略同频

；共振。它不仅要求学生掌握相关科技词汇与表达，更旨在培养其作为“地球村”一员的责任感与可持续发

；展观，引导他们用英语参与全球环境治理的讨论，提升国际话语能力。而“国土安全”主题的拓展，则超

越了传统军事防御的范畴，融入了粮食安全、能源安全、网络安全等非传统安全领域，与“总体国家安全

观”紧密相连。这促使学生在学习英语时，需具备更强的信息甄别能力与批判性思维，能够透过纷繁复杂

的国际资讯，理性看待地獴政治格局，筑牢国家安全意识。二者相辅相成，共同构建了“立足中国，放眼

|世界”的育人框架。通过这些主题的学习，学生不仅能提升语言能力，更能塑造兼具家国情怀与全球胜任

；力的新时代公民，体现了英语教育在培养国家未来建设者中的关键作用。

答案与解析：

文章大意：本文介绍了新落成的黄河国家文化公园。文章阐述了该公园旨在保护黄河的自然风光和文

化遗产的双重作用，并着重说明了公园如何通过现代展示手段和活态文化传统，让古老的文明焕发新生，

从而邀请游客体验中华文明的摇篮。

I.B

细节理解题。根据第四段中的“…thepark...breathesnewlifeintoancientculturethroughmodemdisplay

techniquesandinteractiveexperiences.”可知，公园通过现代展示技术和互动体验为古老文化注入新生命。选

项B“通过使用现代技术和互动方法”与此意相符。选项A“建造新寺庙和现代建筑”文中未提及；选项C“只

关注其令人印象深刻的自然风光”与原文不符，公园也关注文化遗产：选项D“向游客销售当地手工艺品和

食物''是文化体验的一部分，但不是为文化“注入新生命”的主要方式。

2.B

推理判断题。根据第三段中的"...fromtheYangshaoculture.,datingback5,000to7,000years...”可知，仰

韶文化距今已有五千至七千年历史。这个时间点表明该地区的文明发展得非常早。选项B“该地区的文明发

展得非常早，，是合理的推断。选项A“黄河地区仅以农业闻名“过于片面，文中还提到了彩陶；选项C“佛教

是该地区最早的文化”与原文信息矛盾，仰韶文化早于佛教传入：选项D“下游文化比上游文化更先进“文中

并未进行比较，属于无中生有。

3.C

主旨大意题。通读全文可知，文章的核心内容是围绕“黄河国家文化公园”展开的。第一段引出黄河的

背景，第二段介绍公园的建立和目标，第三、四段具体介绍公园内的文化遗产和活态传统，第五段总结并

发出邀请。因此，文章的主要目的是介绍这个新建的文化公园及其价值。选项C”介绍一个新的文化公园及

其重要性''最能概括全文主旨和目的的。选项A、B、D虽然都在文中有所提及，但都是为介绍公园服务的

具体信息，不是文章的主要写作H的。

4.A

推理判断题。根据最后一段中的“Whiletheparkisvast,exploringkeycitiescanofferacondensedyet

profoundexperience.”可知，作者认为公园非常广阔，而探索“关键城市”可以提供一种“浓缩而深刻的体验”。

由比可以推断，作者建议游客参观关键城市是因为这些地方能让游客在有限的时间内高效地领略公园的精

华，选项A”因为它们提供了公园亮点的集中体验”符合此推断。选项B、C、D的内容在文中均没有信息

支持。

答案与解析：

文章大意：本文通过敕勒川草原生态修复的成功案例，阐述了“近自然”的修复理念。文章强调了利用

本地植物物种而非外来物种是恢复生物多样性和生态系统稳定性的核心方法。这种以科学研究和数据平台

为支撑的模式，不仅取得了生态却经济效益，还为中国乃至世界的生态修史工作提供了宝贵的经睑°

I.C

主旨大意题。文章通篇围绕敕勒川草原的修复展开，但其核心并非仅仅描述事件本身，而是揭示其成

功背后的关键方法。文章多次强调使用本地物种的重要性，如第二段的核心思想“touselocalplantsrather

thanforeignones",第四段详细介绍了公司对本地物种的研究和利川，第五段则将这一原则推广到国际。因

此，文章旨在传达的核心信息是“利用本地物种是生态修复成功的关键选项A（草原美景吸引游客）和

选项B（公司商业模式带来经济效益）只是成功的结果，并非文章主旨。选项D（新技术使环保更容易）

过于宽泛，文章聚焦的是“本地物种”这一具体方法。

2.B

推理判断题。文章第二段提到“workingwithnature”的方法是利用本地物种，第三段描述了其结果：“the

newgrasslandcannowsustainitselfwithnaturalrainfallalone''（新草原现在可以仅靠自然降雨维持自身）。这

表明修复后的生态系统具备了自我维持的能力，是稳定和平衡的。由此可以推断，这种方法创造了一个更

稳定、更有弹性的生态系统。选项A（比传统方法更快）文章未提及。选项C（依赖人工浇水和施肥）与

第三段“sustainitselfwithnaturalrainfallalone”的信息相悖。选项D（由M-Grass公司首创）文章未提供足

够信息支持，只说该公司是项目参与者。

3.C

细节理解题。根据第四段最后,句，“Theyalsodevelopedasmartdatasystemtohelpchoosethebest

combinationoflocalplantsforanyspecificenvironment...”，这个智能数据系统的作用是帮助“为任何特定环境

选择最佳的本地植物组合选项C（为某个地点选择最合适的本地植物）是时此信息的准确概括。选项A

（为未来生态项目存钱）、B（预测该地区天气变化）和D（在受控环境中种植外来植物）在文章中均未提

及或与原文不符。

4.B

细节理解题。根据文章最后•段，uTheprincipleisnottoexportChineseseeds,buttohelpothercountries

usetheirownnativeplantstorestoretheirdamagedlands.”其核心原则是“帮助其他国家使用它们自己的本地

植物来修灯受损的土地工诜项B星对此句的同义转述，为正确衿案。诜项A（低价向别国出售中国种子）

与原文“nottoexportChineseseeds”直接矛盾。选项C（为外国政府建造大型公园供其模仿）和D（教其他

国家如何发展旅游业）均不是文章提到的核心原则。

答案与解析：

文章大意：本文主要介绍了中国“绿水青山就是金山银山”的生态文明理念。文章阐述了该理念的起源、

其与中国传统哲学的联系，并详细说明了该理念如何帮助中国在实现经济增长的同时保护环境、成功消除

贫困。最后，文章强调中国的经验为其他发展中国家提供了新的发展模式，并指出生态文明建设需要全球

合作。

I.B

本题为主旨大意题。文章开篇即点明主旨，介绍中国的生态文明理念不仅造福本国，也为全球可持续

发展提供了新路径。全文围绕这一核心理念，阐述了其内涵、在国内的成功实践（如经济增长、扶贫、可

再生能源发展）及其对世界的启示。选项B”介绍中国的生态理念及其全球意义”最能全面、准确地概括全

文书旨。诜项A与文章核心观点相反：诜项C过于片面，文章的重点是介绍中国的成功经验而非批评他国：

选项D范围过窄，文章不仅涉及经济发展，更核心的是生态与发展的结合。

2.B

本题为推理判断题。文章笫三段提到，通过生态农业、生态旅游等新模式，中国帮助近亿农村人口脱

贫，这证明了“改善自然环境可以直接改善民生并创造经济价值”。由此可以推断出，环境保护本身可以成

为创造财富的工具。选项B“环境保护可以成为创造经济财富的工具”正是这一深层含义的推断。选项A文

章未提及；选项C中的“copyexactly”过于绝对，文章说的是提供“alternativemodel”（替代模式）；选项D

文章未提及，属于无中生有。

3.A

本题为细节理解题。文章第二段明确指出，这一生态理念"isdeeplyrootedinthetraditionalChinesebelief

thathumanityshouldexistinharmenywithnature”（深深植根于中国关于人与自然和谐共生的传统信仰）。这

说明该理念是对中国传统哲学的现代诠释。选项A“作为中国传统哲学的现代体现”准确地表达了这一信息。

选项B与文章中大量的事实相悖;选项C与文章中“cuncclsIhcoldmudclofsomedevelopednaliuns”的表述

不符：选项D与文章中“deeplyrootedinthetraditionalChinesebelief的表述相矛盾。

4.B

本题为推理判断题。文章第四段集中阐述了中国经验的全球意义，明确指出“China'sexperienceprovides

boththeoreticalandpracticalguidanceforotherdevelopingcountries.Itshowsthemthatitispossibletodevelop

economicallywithoutsacrificingtheenvironment,offeringavaluablealternativetothetraditionalpathof

mcustnalization."（中国的经验为具他发展中国家提供了埋论和实践指导。它向他们表明，在不牺牲环境的

情况下实现经济发展是可能的，为传统的工业化道路提供了宝贵的替代方案）。由此可知，中国提供的是

一个平衡发展与环保的替代模式,选项B"一个平衡增长与环境保护的替代模式”是对此信息的最佳概括。

选项A与文章观点相反：选项C是对文章的曲解，文章强调的是绿色发展，而非没有规则的发展；选项D

中的“guarantee”（保证）-,词过于绝对，文章并未做出此类承诺。

答案与解析：

文章大意：本文主要介绍了北京市如何利用高科技手段，如创新的PM2.5源解析方法、智能监测网络

和“他脸识别”系统，来全面监测和改善其空气、水质和土壤环境，并阐述了该市在未来通过数字化和智能

化手段进一步加强环境保护的计划。

1.B

主旨大意题。题目间文章的主要目的。文章通篇围绕北京如何运用高科技（如PM2.5源解析、智能

监则点、鱼脸识别系统、未来数字化管理系统等）来保护和改善环境展开。选项B”讨论北京用于环境保护

的高科技方法”最准确地概括了全文的核心内容。选项A”论证技术是解决污染的唯一方案”过7绝对，文章

并未提及“唯一选项C”比较北京与其他城市的空气质量”文章未涉及。选项D”列出北京市生态环境局的

官员姓名”只是文章提及的细节，并非主旨。

2.B

推埋判断题。题目问从''鱼脸识别”系统中可以推断出什么。文章第二段提到，该系统通过观察鱼的种

类和多样性来掌握水质，这是一种“novel叩proach”（新颖的方法）。这表明了将AI和5G技术应用于生态

监测的创新思维。选项B”表明技术可以为环境问题提供创造性的解决方案”是对此信息的合理推断。选项

A♦它完全取代了传统的水质检测方法”无法从文中推出，文章只说它是一种新方法，并未说取代了所有旧

方法。选项C“它对于在小河流使用来说太昂贵了”文章未提及成本。选项D“它是由•家外国科技公司开发

的”与原文“由北京市生态环境保护科学研究院开发”信息不符。

3.C

细节理解题。题目问未来的数字系统旨在解决什么问题。文章最后一段明确指出，该市致力于利用

大数据和人工智能解决“suchasinsufficientintegrationofmonitoringdataformotorvehicles^^（例如机动车监

测数据整合不足的问题）。选项C“缺乏来自车辆监测的关联数据”是对此信息的精准同义转述。选项A“建

立监测站的高成本''文章未提及。选项B“追踪PM2.5来源的困难”在文章开头就已通过新方法解决了。选

项D“硝酸盐在大气中的迁移和转化”是未来研究的一个具体科学问题，不是数字管理系统要解决的集成问

顾,

4.B

推理判断题。题目问文章暗示了北京的环境努力是怎样的。文章前半部分详细描述了已经实施并取

得成效的措施（如PM2.5浓度下降），后半部分则用“Lookingahead”和“Finally”引出了未来的研究计划和数

字化管理系统的构建。这表明北京的努力是“正在进行''和"未来规划”的结合。选项B“它们是当前行动与未

来规划的相结合''准确地反映了这•结构。选项A“它们已经实现了拥有完美洁净城市的最终目标”过于夸大,

文章仍在规划未来。选项C“它们更关注水质而非空气污染”不正确，文章用大量篇幅描述了空勺污染治理.

选项D“它们未能有效降低PM2.5浓度”与原文“annualaveragedensityofPM2.5hasseenamajordrop”事实相

答案与解析：

文章大意：本文主要介绍了在青海湖举办的一场独特的观鸟比赛。文章通过描述该活动如何将竞赛与

教育相结合，阐述了其对当地社区居民（牧民、导游）和外地观鸟爱好者产生的积极影响，强调了此次活

动在提升公众生态保护意以、促进国家公园建设以及拓展对青海湖鸟类世界认知方面的重要价值。

1.B

主旨大意题。文章开篇以一场讲麻引出活动，接着描述了讲座对当地人的教育意义（第二段），然后

点明这是一个以教育为主要目的的观鸟比赛（第三段），最后注述了比赛的过程及其在物种发现和生态认

知上的重要成果（第四、五段）。全文围绕“观鸟比赛”展开，但核心在于强调其“教育”和“保护”的双重价值，

而不仅仅是比赛本身。选项A“观鸟比赛的规则”过于片面；选项C“青海湖的旅游潜力”只是活动的次要方

面；选项D“野外观鸟的挑战”仅在第四段提及，不是文章主旨。选项B“观鸟比赛的教育和保护价值”最准

确地概括了全文的核心内容和写作目的。

2.B

推理判断题。根据第二段，牧民通过讲座”终于知道了我经常看到的那些鸟的名字“，并意识到自己所

在的区域是“许多水鸟的重要家园”；导游则表示可以“为我们的游客提供更好的答案”。这表明他们原本为

鸟类有感性认识，但通
