Paragraph 1:
On the next morning,Xiao Yu and her friends met at the park gate as they agreed.They brought garbage bags,gloves and a small net with them.First,they used the net to fish out plastic bottles and food bags from the lake.Then they picked up litter on the bank and sorted it into different garbage bags carefully.Though they were tired and their clothes got a little dirty,they felt happy when they saw the lake bank become cleaner little by little.
Paragraph 2:
Their actions also attracted the attention of other people in the park.Some parents stopped their children from littering and joined in the cleaning voluntarily.A park worker came over to thank them and said he would suggest adding more trash cans in the park.Weeks later,Xiao Yu visited the park again.The lake water turned clear,lotus flowers bloomed beautifully and wild ducks swam on the water again.She knew that everyone’s small effort could help keep the balance of nature.

第二部分阅读（共20小题，每题2.5分，满分50分）
第一节阅读理解（21-35题）
A篇（应用文·生态保护倡议书）
语篇解读：本文以城市湿地保护为主题，指出湿地面临的非法乱扔、过度踩踏、随意钓鱼等威胁，介绍湿地的生态价值，向市民发出保护湿地的行动号召，并说明具体参与方式，紧扣“自然平衡”单元核心，语言简洁、号召性强。
21.答案：B
段落定位：全文（最后一段Let’s work together to protect our urban wetland and keep the natural balance for our city!（让我们共同努力保护城市湿地，守护城市的自然平衡！））
解析：主旨大意题，文章核心目的是号召市民参与城市湿地保护行动；A（介绍湿地美景）、C（解释湿地生态价值）是铺垫，D（宣布湿地公园开放）无原文依据。
22.答案：B
段落定位：第一段illegal littering,excessive walking on the wetland grass,and random fishing have broken its natural balance（非法乱扔垃圾、过度踩踏湿地草地、随意钓鱼破坏了它的自然平衡）
解析：细节理解题，A、C、D均为湿地面临的威胁，B（志愿清洁）是保护湿地的行为，并非威胁。
23.答案：C
段落定位：第三段The activity will start on May 1st,2026（该活动将于2026年5月1日启动）
解析：推理判断题；A与第二段the wetland...adjusts the climate矛盾，B与第二段Protecting it is not just the government’s duty矛盾，D与第二段provides a living space for more than 50 kinds of birds and 30 kinds of aquatic animals矛盾。
B篇（记叙文·少年守护家乡溪流）
语篇解读：本文讲述14岁少年林浩发现家乡溪流被工厂废水污染后，主动拍照举报、组织同学清理溪流，面对阻挠仍不放弃，最终让溪流恢复清澈的故事，体现“普通人皆能为守护自然平衡贡献力量”的主题，情节简单、情感真挚。
24.答案：B
段落定位：第一段Some small factories nearby began to pour waste water into the stream,and soon the water turned black（附近的一些小工厂开始向溪流排放废水，溪水很快就变黑了）
解析：细节理解题，直接点明溪流污染的核心原因是工厂排放废水，A、C、D均无原文依据。
25.答案：C
段落定位：第二段First,he took photos of the polluted stream and the waste water from the factories,and sent them to the local environmental protection bureau（首先，他拍下污染的溪流和工厂的废水照片，发送到当地环保局）
解析：细节理解题，林浩保护溪流的第一个行动是向环保局举报，A、B为后续行动，D无原文依据。
26.答案：B
段落定位：第四段The villagers all praised Lin Hao for his courage and persistence（村民们都称赞林浩的勇气和坚持），结合前文林浩面对工厂阻挠、村民质疑仍不放弃的情节。
解析：词义猜测题，persistence意为“坚持、毅力”；A（遇困难轻易放弃）、C（害怕面对工厂主）、D（快速改变想法）均与文意相反。
27.答案：C
段落定位：最后一段Lin Hao said.“Nature is our home,and everyone should protect it to keep the balance.”（林浩说：“自然是我们的家，每个人都应该保护它，保持平衡。”）
解析：推理判断题，林浩作为少年守护溪流的故事印证“每个人都能为自然平衡出力”；A（青少年无法为环保做事）、B（保护自然只需要政府行动）、D（被污染的溪流无法恢复）均与文意相反。
C篇（说明文·碳中和下森林的生态价值）
语篇解读：本文以“碳中和”社会热点为背景，介绍森林的核心生态价值（碳汇、防止水土流失、调节气候等），指出全球森林面积减少的现状及危害，列举中西方各国保护森林的具体措施，最后展望森林保护的未来，紧扣“自然平衡”与生态保护主题。
28.答案：B
解析：主旨大意题，文章前两段讲森林的生态价值，第三段讲森林破坏的现状及危害，第四段讲保护森林的措施；A（全球变暖的原因）、C（全球森林火灾现状）、D（中国植树造林的历史）均为文章局部内容。
29.答案：D
段落定位：第二段forests play a key role in absorbing carbon dioxide and releasing oxygen...They can prevent soil erosion...They can also adjust the local climate（森林的作用是吸收二氧化碳释放氧气、防止水土流失、调节气候）
解析：细节理解题，D（为人类生产更多塑料产品）并非森林的生态功能，且塑料产品会污染环境，与森林保护相悖。
30.答案：B
段落定位：第三段This not only reduces the earth’s carbon sink capacity but also destroys the living space of wild animals and plants...For example,the Amazon rainforest...has lost 15%of its area...leading to the extinction of more than 200 kinds of rare species（这不仅降低了地球的碳汇能力，还破坏了野生动植物的生存空间，举亚马逊雨林的例子是为了具体说明森林破坏带来的严重恶果。
31.答案：A
解析：最佳标题题，全文围绕“森林的生态价值”和“森林保护”展开，核心是森林对维持地球自然平衡的关键作用；B（碳中和：世界的新挑战）、C（砍伐森林：全球变暖的主因）、D（中国的植树造林工程：巨大的成功）均偏离核心主题。
D篇（议论文·人类活动与自然平衡）
语篇解读：本文围绕“人类活动与自然平衡的关系”展开论述，先指出工业革命后人类活动破坏自然平衡的现状及危害，再介绍全球各地保护自然、恢复平衡的积极行动，最后反驳“发展经济比环保重要”的错误观点，提出“经济发展与环保并行”的可持续发展理念，是单元主题的深度延伸。
32.答案：C
段落定位：第四段Only when we develop the economy while protecting the environment,and take the road of sustainable development,can we live in harmony with nature forever（只有在保护环境的同时发展经济，走可持续发展道路，我们才能永远与自然和谐共处）
解析：观点态度题，作者主张经济发展与环境保护同时进行；A、B、D均与作者观点相悖。
33.答案：B
段落定位：第一段But since the Industrial Revolution,human activities have had an increasingly great impact on nature,and the natural balance has been broken in many parts of the world（但自工业革命以来，人类活动对自然的影响越来越大，自然平衡在世界许多地方被打破）；第二段具体介绍工业、农业发展带来的环境问题。
解析：细节理解题，工业革命后自然平衡被破坏的主要原因是工业、农业等人类活动。
34.答案：C
段落定位：第三段More and more citizens have changed their lifestyles,choosing low-carbon travel such as walking and taking public transport...（越来越多的市民改变生活方式，选择步行、乘坐公共交通等低碳出行方式……）
解析：细节理解题，C是文中提到的保护自然的积极行动；A、B、D均为破坏自然的行为。
35.答案：B
段落定位：第二段All these activities have destroyed the ecological chain and broken the natural balance,resulting in more and more natural disasters such as floods,droughts and sandstorms（所有这些活动都破坏了生态链，打破了自然平衡，导致洪水、干旱、沙尘暴等自然灾害越来越多）
解析：推理判断题，文中明确指出自然平衡被破坏引发了更多自然灾害，二者联系紧密；A与第一段For thousands of years,human beings lived in harmony with nature矛盾，C与第三段These actions have helped to restore the natural balance in some areas矛盾，D与第三段*Many countries have formulated strict environmental protection laws...*的积极影响相悖。
第二节七选五（36-40题，说明文·日常生活守护自然平衡）
语篇解读：本文为说明文，核心是“普通人如何通过日常小事守护自然平衡”，先提出核心观点，再从节约用水电、低碳出行、减少塑料使用、种植绿植四个方面给出具体方法，最后总结升华，考点涵盖逻辑衔接题、细节匹配题，贴合高考题型。
36.答案：E
解析：逻辑衔接题，前文说“每个人都能通过小事守护自然平衡”，E（事实上，正是日常的小事带来了最大的改变）承接上文，引出下文具体方法，衔接自然。
37.答案：D
解析：细节匹配题，前文列举“关水龙头、关灯/空调”的小事，D（这些小事能节约大量自然资源）解释这些行为的意义，与后文“水电源于自然资源，节约即减少开采”呼应。
38.答案：F
解析：细节匹配题，前文讲“低碳出行”，后文说“远路坐公共交通”，F（近路可以步行或骑自行车）与后文形成“近路+远路”的完整低碳出行建议，逻辑连贯。
39.答案：C
解析：逻辑衔接题，前文提出“减少塑料使用”，C（塑料是白色污染的主要成因之一）解释原因，引出后文“用可循环用品替代塑料”的具体做法。
40.答案：B
解析：细节匹配题，前文讲“种植绿植”，B（绿植能吸收二氧化碳、释放氧气）介绍绿植的生态作用，与后文“让生活环境更美丽”形成并列，贴合自然平衡主题。

14-year-old Lin Hao has lived in a small village by the stream since he was born.The stream used to be clear and clean,with small fish swimming in it and villagers taking water for daily use.But half a year ago,things changed.Some small factories nearby began to pour waste water into the stream,and soon the water turned black,with a terrible smell.The fish died,and villagers had to buy bottled water for drinking.
Lin Hao felt sad and angry when he saw the dirty stream.He decided to do something to change it.First,he took photos of the polluted stream and the waste water from the factories,and sent them to the local environmental protection bureau.Then,he organized his classmates to pick up litter along the stream every weekend and put up warning signs that read“Protect the Stream,Keep Nature in Balance”.
At first,some factory owners wanted to stop him,and some villagers thought he was wasting time.But Lin Hao didn’t give up.He kept calling the environmental bureau to ask about the progress of the investigation.After two months,the local government took action:the illegal factories were closed,and workers were sent to clean the stream.
Now the stream is becoming clear again,and small fish have come back.The villagers all praised Lin Hao for his courage and persistence.“I just did what I should do,”Lin Hao said.“Nature is our home,and everyone should protect it to keep the balance.”
24.Why did the village stream become polluted

In the context of carbon neutrality,forests have become one of the most important natural resources for keeping the earth’s ecological balance,and their ecological value is getting more and more attention worldwide.As the“carbon sink of the earth”,forests play a key role in absorbing carbon dioxide and releasing oxygen,which can effectively reduce greenhouse gas emissions and slow down global warming.
A mature forest can absorb about 22 tons of carbon dioxide per hectare every year,according to the latest environmental research in 2025.Besides carbon sequestration,forests also have many other ecological functions.They can prevent soil erosion,because tree roots can fix the soil and reduce the loss of fertile land caused by rain and wind.They can also adjust the local climate by increasing air humidity and reducing temperature in hot summer.
However,the world’s forest area is decreasing at a speed of 10 million hectares every year due to deforestation,forest fires and agricultural expansion.This not only reduces the earth’s carbon sink capacity but also destroys the living space of wild animals and plants,breaking the natural balance.For example,the Amazon rainforest,the largest rainforest in the world,has lost 15%of its area in the past 20 years,leading to the extinction of more than 200 kinds of rare species.
To protect forests and maintain natural balance,many countries have taken active measures.China has carried out the afforestation project for more than 40 years,and the forest coverage rate has increased from 12%to 24.02%by 2025.Many countries also have made laws to stop illegal deforestation and set up more nature reserves to protect forest resources.
With the joint efforts of all countries,it is believed that the world’s forest area will stop decreasing and even increase in the near future,which will help the earth achieve carbon neutrality and keep the ecological balance stably.

Nature is a complex and balanced system,and every living thing in it has its own role to play.For thousands of years,human beings lived in harmony with nature,depending on it for food,water and shelter,and taking only what they needed.But since the Industrial Revolution,human activities have had an increasingly great impact on nature,and the natural balance has been broken in many parts of the world.
On one hand,the rapid development of industry and agriculture has brought great convenience to human life,but it has also caused serious environmental problems.Factories pour waste water and gas into rivers and the air,leading to water and air pollution;excessive use of chemical fertilizers and pesticides in agriculture damages the soil and kills beneficial insects;deforestation for urban expansion and wood makes many wild animals lose their homes.All these activities have destroyed the ecological chain and broken the natural balance,resulting in more and more natural disasters such as floods,droughts and sandstorms.
On the other hand,more and more people have realized the importance of keeping nature in balance,and positive changes have taken place around the world.Many countries have formulated strict environmental protection laws,closed illegal polluting factories,and carried out afforestation and wetland restoration projects.More and more citizens have changed their lifestyles,choosing low-carbon travel such as walking and taking public transport,reducing the use of plastic products,and participating in voluntary environmental protection activities.These actions have helped to restore the natural balance in some areas and reduced the frequency of natural disasters.
Some people think that human development is more important than environmental protection,and that protecting nature will slow down economic growth.But this idea is wrong.In fact,keeping nature in balance is the foundation of sustainable human development.If the natural balance is broken completely,human beings will lose their living environment,and economic development will become meaningless.Only when we develop the economy while protecting the environment,and take the road of sustainable development,can we live in harmony with nature forever.
Nature is our only home.It’s time for all human beings to take joint action.No matter how small the action is,as long as we stick to it,we can help restore the natural balance and create a better world for ourselves and future generations.
32.What is the author’s attitude towards the relationship between human development and environmental protection
A.Human development is more important than environmental protection
B.Environmental protection will completely stop economic development
C.We should develop economy and protect the environment at the same time
D.We should give up economic development to protect nature completely
33.What is the main cause of the broken natural balance since the Industrial Revolution
A.The change of the earth’s climate and natural disasters
B.Human activities such as industrial and agricultural development
C.The decrease of the world’s population and living space
D.The extinction of many wild animals and plants
34.Which of the following is a positive action for protecting nature mentioned in the passage
A.Pouring factory waste water into rivers randomly
B.Using a lot of chemical fertilizers in agriculture
C.Choosing low-carbon travel such as walking and taking public transport
D.Cutting down trees for urban expansion and wood
35.What can we infer from the passage
A.Human beings have never lived in harmony with nature
B.Natural disasters are closely related to the broken natural balance
C.There is no way to restore the broken natural balance
D.Environmental protection laws have no effect on protecting nature

Keeping nature in balance is not a big thing that only the government can do.Every one of us can make it in our daily life with small actions.36.______Here are some simple and practical ways for us to follow.
First,save water and electricity in our daily life.Turn off the tap when we brush our teeth,and turn off the lights and air conditioners when we leave the room.37.______Water and electricity are mostly produced by natural resources,and saving them means reducing the exploitation of natural resources.
Second,change our travel habits and choose low-carbon travel.38.______If we need to go to a far place,we can take public transport such as buses and subways instead of driving private cars.Low-carbon travel can reduce carbon emissions and air pollution effectively.
Third,reduce the use of plastic products.39.______We can use reusable shopping bags,glass water bottles and wooden chopsticks instead of plastic ones.Plastic products are difficult to decompose and will pollute the soil and water for hundreds of years.
Fourth,plant more green plants in our living space.We can plant some flowers and trees in our yard or put some potted plants on the balcony.40.______They can also make our living environment more beautiful.
Small actions accumulate into great power.Let’s start from ourselves and from small things,and use our own actions to protect nature and keep the natural balance.
A.Private cars are the only way for us to travel far
B.Green plants can absorb carbon dioxide and release oxygen
C.Plastic is one of the main causes of white pollution

It was a sunny weekend morning,and 16-year-old Xiao Yu went to the city park with her little sister.The park is near their home,and they used to go there to play every weekend,because there is a beautiful lake in the park with many lotus flowers and wild ducks on it.But this time,Xiao Yu found that the park was not as beautiful as before.
The lake water was no longer clear,and there was a lot of litter such as plastic bottles,food bags and paper boxes floating on the surface.The lotus flowers were withered in some places,and the wild ducks were nowhere to be seen.Some children were throwing stones into the lake,and some adults were sitting on the grass and littering randomly.
Xiao Yu felt very sad.She remembered that the lake was clean and clear last year,with lotus flowers blooming in summer and wild ducks swimming happily on the water.She knew that the random littering had polluted the lake and broken the natural balance of the park.
Xiao Yu told her little sister not to litter and picked up a plastic bottle from the lake bank.Then she looked around and found that there were only a few trash cans in the park,and some of them were full.She thought for a while and decided to do something to change the situation.
