Ⅰ.阅读理解(每小题5分，共40分) A (2025·福建泉州高二上期末) 　　One of the world's rarest birds，the greater adjutant stork (大秃鹳)，known locally as the Hargila was once considered “disease carrier” and “ugly” by the villagers in Assam who would destroy their nests.Dr Purnima Devi Barman，an Indian wildlife biologist，has been committed to protecting the endangered birds and changing the opinion of villagers. Barman's love of animals started at age five while she lived with her grandparents by the Brahmaputra River，where she often encountered all sorts of birds coming to the fields and wetlands. 素能提升练 Recalling one of the moments that changed her life，Barman said that while she was doing her PhD paper on the greater adjutant stork，she got a call telling her that a villager had cut the nest-tree of adjutant storks and nine chicks fell down.When she communicated with the villager and his neighbours，she was shouted at and laughed at.“The villager was so angry at me for rescuing the birds.One of his neighbours said that ‘we cannot keep it in our backyard.It makes our area very dirty and smelly’，” Barman recalled.But with her tireless effort，she managed to change his views and the villager joined her in protecting the birds. “After that，I experienced the power of the community and decided to make use of it for stork conservation，” Barman added.She then started the Hargila Army of villagers，especially the network of thousands of families across villages who travel door to door with her in spreading awareness and educating people about stork conservation. “Initially women hesitated to come out and volunteer.But one day，I organized a cooking contest and scores of people participated and that's how all our gatherings revolved (围绕) around stork conservation and restoring their ecosystem.Slowly and gradually，we increased the network，and now we are saving many other endangered species，” Barman said. 语篇解读　本文是一篇记叙文。文章主要讲述了印度野生生物学家普尔尼玛·德维·巴曼博士对于大秃鹳的保护工作。 1.What has led to the decrease of the storks in Assam？ A.The attack of diseases. B.High demand for wood. C.Villagers' negative attitude. D.Ignorance of their situation. 细节理解题。根据第一段“One of the world's rarest birds，the greater adjutant stork (大秃鹳)，known locally....destroy their nests.”可知，村民的消极态度导致了大秃鹳的减少。故选C。 √ 2.What drove Barman to found “the Hargila Army of villagers”？ A.Her bird-watching experience. B.Her PhD study on the bird. C.Her effort to prevent tree cutting.

D.By hosting voluntary activities. 细节理解题。根据最后一段“But one day，I organized a cooking contest and scores of people participated...their ecosystem.”可知，巴曼一开始通过组织烹饪比赛让女人参与进来。故选B。 √ 4.What can we learn about Barman from her deeds？ A.She strives to preserve wildlife. B.She values diverse views. C.She prioritises academic education. D.She cares about villagers' welfare. 细节理解题。根据第一段“Dr Purnima Devi Barman，an Indian wildlife biologist，has been committed...opinion of villagers.”以及倒数第二段“She then started the Hargila Army of villagers，especially...stork conservation.”可知，巴曼努力保护野生动物。故选A。 √ B (2025·山东济南高二期中) Coral reefs in Florida have lost an estimated 90％ of their corals in the last 40 years.This summer，a marine heat wave hit Florida's coral reefs.The record high temperatures created an extremely stressful environment for the coral reefs，which are currently also experiencing intense coral bleaching (白化). A coral is an animal，which has a symbiotic relationship with a microscopic algae (藻类).The algae gets energy from the sun and shares it with the coral internally.The coral builds a rock-like structure，which makes up most of the reef，providing homes and food for many organisms that live there.Coral bleaching is when the symbiotic relationship breaks down.Without the algae，the corals appear white because the rock skeleton becomes visible.If the bleaching continues for an extended period，the corals can starve to death without the energy. Florida is on the front lines of climate change.It is also on the cutting edge of restoration science.Many labs，institutions and other organizations are working nonstop to protect and maintain the coral reefs.This includes efforts to understand what is troubling the reef，from disease outbreaks to coastal development impacts.It also includes harvesting coral spawn (卵)，or growing and planting coral parts.Scientists moved many coral nurseries into deeper water and shore-based facilities during this marine heat wave.They are digging into the DNA of the coral to discover which species will survive best in future. There are some bright spots in the story，however.Some corals have recovered from the bleaching，and many did not bleach at all.In addition，researchers recorded coral spawning.Although it's not clear yet whether the larvae (幼虫) will be successful in the wild，it's a sign of recovery potential.If the baby corals survive，they will be able to regrow the reef.They just have to avoid one big boss：human-induced climate change. 语篇解读　本文是一篇说明文。文章主要介绍了佛罗里达州的珊瑚礁因受高温天气影响而出现白化现象以及专家们为保护珊瑚礁所采取的措施。 5.What does the underlined word “symbiotic” in Paragraph 2 mean？ A.Reliable. B.Opposite. C.Harmonious. D.Contradictory. 词义猜测题。根据画线词所在句的下文“The algae gets energy from the sun and shares it...food for many organisms that live there.”可知，珊瑚分享藻类从太阳获得的能量，珊瑚礁为生活在那里的许多生物提供了家园和食物；因此，藻类与珊瑚之间是相互依存的共生关系。由此可知，画线词所在句子意为“珊瑚是一种动物，它与一种微小的藻类有共生关系”，因此画线词symbiotic的意思是“共生的，相互依赖的”，与reliable的意思一致。故选A项。 √ 6.What caused the coral bleaching？ A.The rock skeleton. B.The microscopic algae. C.The high temperatures. D.The symbiotic relationship. 细节理解题。根据第一段中“The record high temperatures...experiencing intense coral bleaching(白化).”可知，高温引起了珊瑚礁的白化现象。故选C项。 √ 7.Which is NOT the efforts scientists made to help coral reefs？ A.Transferring coral nurseries. B.Growing and planting coral spawn. C.Researching the DNA of the coral. D.Figuring out the reasons for problems. 细节理解题。根据第三段中“Many labs，institutions and other organizations...which species will survive best in future.”可知，科学家们在不遗余力地保护和维护珊瑚礁，他们研究困扰珊瑚礁的因素、孵化珊瑚卵、种植珊瑚枝节、高温中把许多珊瑚苗圃移到了更深的水域和海岸设施中以及深入研究珊瑚的DNA以发现未来存活最好的物种。故B选项“种植珊瑚卵”不是科学家所采取的保护措施。故选B项。 √ 8.Which of the following best describes the impact of scientists' efforts？ A.Identifiable. B.Predictable. C.Far-reaching. D.Effective. 推理判断题。根据最后一段中“There are some bright spots in the story，however.Some corals have recovered from the bleaching，and many did not bleach at all.”可知，经过科学家的努力，一些珊瑚已经从白化中恢复过来，许多珊瑚根本没有白化。由此可知，科学家们的努力有了成效。故选D项。 √ Ⅱ.完形填空(每小题2分，共30分) (2025·贵州遵义高二上期末) 　　Near my home there is a small lake with a walk path.Back in the days when my children were younger，we would 　1　 to it sometimes and walk the path.It always felt so good to be close to nature and the 　2　 of Nature's creation.
