The mangrove wetlands(红树林湿地)of Shenzhen’s Futian and Hong Kong’s Mai Po are very valuable. Every year, many waterbirds fly from East Asia to Australia. These wetlands are a key place for them to rest. These years, Shenzhen and Hong Kong have worked together to protect these important wetlands.
Why are these mangrove wetlands so important? Because they are like nature’s protectors. They make a natural wall, protecting coasts from big storms(暴风雨). Besides, the thick forest of mangrove trees provides a perfect home for birds. They build nests there and look after their babies. “Even during storms, baby birds are safe in the mangroves,” said Simon Wong from Hong Kong’s nature team. What’s more, mangroves help take in CO₂ and clean the water. As a result, they are helpful for both nature and humans.
To protect the wetlands together, Shenzhen and Hong Kong have used different ways since 2023. One of them is to protect birds’ homes with the help of modern AI technology. Thanks to their efforts, the population(数量)of endangered birds in the wetlands has grown. For example, there were only about 300 black - faced spoonbills(黑脸琵鹭)around 30 years ago. Now there are nearly 7,000.
In November 2024, the two cities started a new part of their teamwork. The International Mangrove Center(IMC)in Shenzhen opened. The IMC does research on mangrove protection, shares useful ideas and gives classes to the public. Its opening helps Shenzhen and Hong Kong work better to protect the wetlands. It also shows the world how cities can join hands to protect the environment.

答案
【文章大意】本文是一篇说明文，主要讲述深圳和香港合作保护红树林湿地，介绍了湿地的价值、保护措施、成效和 IMC 的成立。
21. C 代词指代题。根据“Every year, many waterbirds fly from East Asia to Australia. These wetlands are a key place for them to rest.”可知，每年都有许多水鸟从东亚飞到澳大利亚，这些湿地是它们休息的关键场所。所以画线词指代水鸟。故选 C。
22. D 段落大意题。根据“As a result, they are helpful for both nature and humans.”并结合本段内容可知，本段明确说明红树林的作用：形成天然屏障保护海岸，为鸟类提供安全家园，吸收 CO₂和净化水源。即红树林不仅对自然有好处，对人类也有好处。故选 D。
23. D 写作意图题。根据“Thanks to their efforts, the population of endangered birds in the wetlands has grown.”可知，第三段提到黑脸琵鹭的数量从 30 年前的约 300 只增加到近 7000 只，是为了举例证明保护措施（如 AI 技术）的成功。故选 D。
24. B 推理判断题。根据“Its opening helps Shenzhen and Hong Kong work better to protect the wetlands. It also shows the world how cities can join hands to protect the environment.”可知，它的开放有助于深圳和香港更好地保护湿地，它还向世界展示了城市如何携手保护环境。即 IMC 指导城市更好地合作，保护自然。故选 B。
25. D 主旨大意题。本文主要讲述深圳和香港合作保护红树林湿地，介绍了湿地的价值、保护措施、成效和 IMC 的成立。所以本文的主旨是：两个城市共同保护红树林湿地。故选 D。

解析
【分析】
这是一篇环保主题的说明文阅读，解题的整体思路是先通读全文梳理核心脉络，明确文章围绕深港两地合作保护红树林湿地展开，再针对每道小题回原文精准定位对应内容，逐一排除干扰项得出答案：做代词指代题要往前文找距离代词最近的相关指代对象；细节理解题要将选项和原文内容逐一比对，排除和原文表述相反、无中生有的错误选项；写作意图题要找到例子所支撑的前文观点；推理判断题不能选原文直接明确给出的内容，要做合理的延伸推导；主旨大意题要选择能覆盖全文核心内容的选项，排除仅描述局部细节的干扰项。
【解析】
21. 代词指代题：定位第一段划线词所在句，前一句提到“Every year, many waterbirds fly from East Asia to Australia. These wetlands are a key place for them to rest”，湿地是供长途迁徙的水鸟休息的关键场所，因此划线的them指代前文提到的水鸟，选C。
22. 细节理解题：逐一比对第二段内容：A选项和原文“Even during storms, baby birds are safe in the mangroves”表述相反；B选项原文说明红树林是保护海岸抵御暴风雨，并非保护高楼；C选项原文提到红树林可以吸收二氧化碳、净化水体，并非产生大量二氧化碳和脏水；D选项完全对应第二段尾句“they are helpful for both nature and humans”，说明红树林对自然和人类都有益，选D。
23. 写作意图题：第三段举黑脸琵鹭数量从300只增长到近7000只的例子，是为了佐证前文的观点“Thanks to their efforts, the population of endangered birds in the wetlands has grown”，直观展示保护鸟类栖息地的工作取得了显著成效，选D。
24. 推理判断题：逐一比对最后一段内容：A选项原文仅说明IMC会开展红树林保护相关研究、给公众授课，并未提到学生可以在IMC内部做研究；C选项原文没有提到IMC的核心工作是建造更多红树林；D选项属于完全不符合逻辑的错误表述，不可能仅靠IMC就无需担忧湿地问题；B选项对应原文“Its opening helps Shenzhen and Hong Kong work better to protect the wetlands. It also shows the world how cities can join hands to protect the environment”，可合理推断出IMC能够引导城市更好协作、共同保护自然，选B。
25. 主旨大意题：全文依次介绍了红树林湿地的价值、深港两地多年来的联合保护措施、保护取得的成效、国际红树林中心的成立，核心主线是深圳和香港两座城市携手共同保护红树林湿地，A、B、C都属于文章的局部细节，无法覆盖全文内容，选D。
【答案】
21.C 22.D 23.D 24.B 25.D
【知识点】
代词指代判断，细节信息理解，主旨大意把握
【点评】
本题属于初中英语阅读的典型常规题型，考点覆盖了阅读理解最常考的5类经典题型，整体贴合环保热点主题，难度梯度设置合理，学生解题时要注意避开“以偏概全选局部细节当主旨”“主观臆断脱离原文推导”两类常见失分陷阱，所有判断都要严格依托原文给出的信息。
