Most of us see them in zoos. But there is one kind of tiger you might never see—the South China Tiger. It is one of the most endangered (濒危的) animals in the world. “Endangered” means there are very, very few of them left alive in the wild. Long ago, thousands of these beautiful tigers lived in the mountains and forests of south China. They had bright orange fur with dark black stripes. They were strong and skilled hunters (捕猎者). But now, scientists think there are almost no South China Tigers living freely in nature. What happened? First, people cut down many forests to build farms and cities. This destroyed the tigers’ habitat—the natural place where an animal lives. Without a forest, tigers lose their home and their food. Second, some people hunted tigers for their fur or for medicine. This made the number of tigers drop quickly. Is there any hope for the South China Tiger? Yes! China is trying very hard to save them. Special places called reserves (保护区) are built. A reserve is a protected area where animals can live safely. Some tigers live in zoos, and scientists hope to teach their babies how to live in the wild again. It is a difficult plan, but people are working on it. We must remember: Every animal is important in our world. Losing the South China Tiger would not just mean losing a big cat. It would mean losing a part of China’s natural beauty forever. Protecting them is protecting our future. 11. What is TRUE about the South China Tiger in the past? A. They lived in zoos around the world. B. They had yellow fur with white stripes. C. They were good at hunting in forests. D. They were found in many countries. 12. In Paragraph 3, the underlined word “destroyed” most probably means ________. A. 建造 B. 破坏 C. 描绘 D. 寻找 13. Which is NOT a reason for the South China Tiger becoming endangered? A. Losing their habitat because of building. B. Being hunted by people for different uses. C. Living in reserves that are too small. D. Not having enough food and home. 14. What can we infer from Paragraph 4? A. All South China Tigers now live in the wild freely. B. It is an easy job to save the South China Tiger. C. People have given up trying to protect this tiger. D. China is taking action to help the tigers survive. 15. What is the main purpose of this passage? A. To tell people how to hunt South China Tiger. B. To describe the life of South China Tiger in a zoo. C. To explain why and how to save the South China Tiger. D. To ask more people to visit forests of south China. 【答案】11. C 12. B 13. C 14. D 15. C 【解析】本文是一篇说明文，主要介绍了华南虎这一濒危动物的现状，阐述了其濒临灭绝的原因，包括栖息地破坏、人类捕猎等，并说明了中国为保护华南虎所采取的措施，最后强调保护华南虎的重要意义。 11. 根据第二段 “They were strong and skilled hunters.” 可知，过去的华南虎是强大且技艺高超的捕猎者，即擅长捕猎。 12. 根据第三段 “First, people cut down many forests to build farms and cities. This destroyed the tigers’ habitat—the natural place where an animal lives.” 可知，人类砍伐森林建农场和城市，导致老虎失去了赖以生存的自然栖息地。 13. 第三段提到了两个原因：一是人类砍伐森林破坏了栖息地，使老虎失去家园和食物；二是人类猎杀老虎。选项C“保护区太小”文中并未提及，因此不是导致华南虎濒危的原因。 14. 根据第四段 “China is trying very hard to save them. Special places called reserves are built. A reserve is a protected area where animals can live safely.” 可知，中国正在努力拯救华南虎，建立了保护区等，说明中国正采取行动帮助老虎生存。 15. 全文先介绍华南虎的濒危现状，接着分析原因，最后说明中国正在采取的保护措施并呼吁人们保护它们，因此主要目的是解释为什么以及如何拯救华南虎。 B 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 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. 16. What does the underlined word “them” in paragraph 1 mean? A. Cities. B. Wetlands. C. Waterbirds. D. Mangroves. 17. What can we learn from paragraph 2? A. Mangroves are unsafe for baby birds. B. Mangroves can protect tall buildings from storms. C. Mangroves can produce a lot of CO₂ and dirty water. D. Mangroves are good for not only nature but also people. 18. Why does the writer talk about black-faced spoonbills’ population? A. To introduce modern AI technology. B. To tell readers what the birds look like. C. To explain why endangered birds are important. D. To show the success of protecting birds’ homes. 19. What can we infer (推断) from the last paragraph? A. Students can do research on mangrove protection in the IMC. B. The IMC guides cities to work better together and protect nature. C. The IMC mainly helps the two cities to build more mangrove forests. D. People don’t need to worry about wetland problems because of the IMC. 20. What is the main idea of the passage? A. Mangroves provide safe homes for waterbirds. B. The IMC in Shenzhen helps protect the wetlands. C. There are more black-faced spoonbills in Shenzhen. D. The two cities protect the mangrove wetlands together. 【答案】16. C 17. D 18. D 19. B 20. D 【解析】本文主要讲述深圳和香港合作保护红树林湿地，包括湿地的价值、保护措施、成效和IMC的成立。 16. 词句猜测题。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。所以划线词指代水鸟。故选C。 17. 主旨大意题。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。 18. 推理判断题。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）的成功成果。故选D。 19. 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。 20. 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，包括湿地的价值、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。 C More researchers are turning to artificial intelligence (AI) to monitor the environment and support endangered creatures. Unlike traditional methods that can damage the environment or require considerable time and physical work, AI has the ability to quickly and effectively deal with large quantities of data (数据). Creatures are disappearing at a speed thousands of times faster than that millions of years ago, with one million creatures endangered. The United Nations set a goal in 2020 to safeguard at least 30% of Earth’s land and oceans by the end of 2030. AI is “imperfect” but could make important discoveries faster and earlier, says Nicolas Miailhe, founder of The Future Society, an organization that aims to better manage AI. “We need skilled humans to design AI models and check and collect data.” A type of AI model called a convolutional neural network (CNN) has been developed to recognize bird sounds. The CNN is able to pick out 75 kinds of the birds the researchers have. “Our results prove that AI is ready for recognizing creatures in the wild from sound,” says Maller, the team leader. “All that is needed now is more training data collected by humans.” Besides monitoring creatures in real time, AI can be used to model the impacts of human activities on the environment and rebuild historical changes. Researchers have used AI to discover how a century’s environmental damage in a river has led to creature loss. Although it is well-known that human activities have resulted in creature loss in rivers and lakes, little is known about which activities have the largest impact. “AI will do soon,” says Luisa Orsini, a researcher from the University of Birmingham. 21. Which is true about AI used in monitoring the environment? A. It is being in fashion. B. It will do the job more quickly and effectively. C. Considerable time and physical work are needed. D. It does less harm to the environment than the traditional methods. 22. What can we infer from Nicolas Miailhe’s and Muller’s words? A. AI’s ability is greater than human’s. B. AI’s ability is not as great as people think. C. AI’s ability is much greater than people imagine. D. AI’s ability cannot be achieved without human supports. 23. What does the underlined word “impacts” in Paragraph 4 mean? A. Effects. B. Choices. C. Benefits. D. Purposes. 24. What is the structure of the article? (P=paragraph) A. ①/②③④/⑤ B. ①/②③/④/⑤ C. ①②/③④/⑤ D. ①/②③④⑤ 25. What is the best title for the passage? A. Why Researchers has Turned to AI. B. How AI Can Help Save Endangered Creatures. C. Why AI Can Help with Environmental Protection. D. How Scientific Researches have Been Changed by AI. 【答案】21. B 22. D 23. A 24. D 25. B 【解析】本文是一篇说明文。文章主要介绍应用人工智能来监测环境并拯救濒危生物。 21. 细节理解题。根据第一段中的“Unlike traditional methods that can damage the environment or require considerable time and physical work, AI has the ability to quickly and effectively deal with large quantities of data (数据).”可知，人工智能将更快、更有效地完成监测环境这项工作。故选B。 22. 推理判断题。根据第二段中的“AI is ‘imperfect’ but could make important discoveries faster and earlier”以及第三段中的“Our results prove that AI is ready for recognizing creatures in the wild from sound”可知，人工智能的需要人收集数据来训练。故选D。 23. 词句猜测题。根据倒数第二段中的“Besides monitoring creatures in real time, AI can be used to model the impacts of human activities on the environment and rebuild historical changes.”可知，除了实时监测生物外，人工智能还可以用来模拟人类活动对环境的影响，重建历史变化，所以划线词的含义是“影响”，所以A项符合。故选A。 24. 篇章结构题。通读全文可知，第一段总述应用人工智能来监测环境并拯救濒危生物；第二段至第五段具体介绍人工智能具体的用途及方法。故选D。 25. 最佳标题题。通读全文可知，文章主要介绍应用人工智能来监测环境并拯救濒危生物，所以B项符合。故选B。 第二节 短文填空 以下是一则短文, 请阅读短文, 并从下列六个句子中选择五个还原到原文中, 使原文的意思完整、连贯。并在答题卡上将相应的字母编号涂黑。（共5 小题, 每小题1分） Today, a kind of animal is an endangered species (物种). This means there are very few animals of that kind left on Earth. The animals could face extinction. 26 When a type of animal is extinct, it is gone forever. One problem for animals is that their living places are sometimes destroyed by humans. As human populations increase, more and more space is needed. Building houses for people to live in forces animals to leave their natural homes. Trees are cut down to make room for homes and businesses. Swamps (沼泽) are filled in so that neighborhoods can expand (扩展). The living places are destroyed. The animals have nowhere else to go. 27 Humans must stop the extinction of animals because of the loss of their living places. We have to learn more about animal populations when considering building things. Other choices may not be so convenient. 28 Better planning can make a difference. It is still possible to keep so many kinds of animals for future children to enjoy. Another major problem is overhunting by humans. 29 The governments of countries around the world must agree on laws about protecting animals. Some animals may have large enough populations so hunting will not put them in danger. Others must be protected. 30 Some organizations are working hard to create living places for them. Breeding (繁殖) programs are helping animal populations increase. We all have to know the problem and think before we act. The things we do can have an effect on more than just ourselves. A. This is a worldwide problem. B. Extinction is when all the animals of that kind die. C. However, they can be helpful to the lovely animals. D. It is important for animals to have enough food to eat. E. There is still hope for animals on the endangered species list. F. Without a living place, the number of animals begins to go down. 【答案】26. B 27. F 28. C 29. A 30. E 【解析】本文主要讲述了动物正面临着灭绝的风险以及人类应该采取的措施。 26. 根据“The animals could face extinction.”可知，讲述什么是灭绝，选项B“灭绝是指那种动物全部死亡。”符合语境，故选B。 27. 根据“The animals have nowhere else to go.”可知，本段主要讲述了动物没有了生存空间，选项F“没有了生存的地方，动物的数量开始减少。”符合语境，故选F。 28. 根据“Other choices may not be so convenient.”和“Better planning can make a difference. It is still possible to keep so many kinds of animals for future children to enjoy.”可知，人类能够帮助动物，选项C“然而，他们可以帮助可爱的动物。”符合语境，故选C。 29. 根据“Another major problem is overhunting by humans.”可知，讲述过度捕猎是一个全球性问题，因此需要全世界政府的帮助，选项A“这是一个世界性的问题。”符合语境，故选A。 30. 根据“Some organizations are working hard to create living places for them.”可知，讲述一些机构为动物所作的努力，选项E“濒危物种名单上的动物仍然有希望。”符合语境，故选E。 第三节 信息匹配（共 5小题, 每小题1分） 配对阅读。左栏是五位学生的需求，右栏是七条关于动物的信息，请为每位学生找到合适的信息。选项中有两项为多余项。 31 Lin Mei hears that tigers are in danger now.

Emperor penguins can grow up to 1.2 meters tall, and they are the 36 (large) of all the penguin kinds. In 2022, they were listed as endangered animals because the Antarctic sea ice that they live 37 is becoming smaller and smaller. Now scientists are using high technology to follow them and learn more about how 38 (protect) them. One of the 39 (way) researchers are able to do this is by looking at pictures taken by satellites above the Earth. Large groups of emperor penguins can be seen from space. When scientists first started using satellites to look at the penguins, there were only 28 groups. So far, scientists have discovered 66 groups. Even 40 (use) satellites, it is so difficult to count how many penguins live in different groups. Scientists can improve population estimates (估计) by watching the area’s weather 41 (careful). Measuring the wind speed and temperature can help predict if the penguins gather closely together or spread apart across the ice. If scientists know 42 the weather was like when the pictures were taken, they can estimate how many penguins are pictured. Scientists can also watch penguins' movements by giving 43 (they) special electronic tags. A scanner is carried by a robot, 44 it can read information on the tags. The robot also uses AI to recognize the penguins. It moves very slowly so that it doesn’t make the birds stressed. Daniel, one of the penguin researchers, 45 (hope) the technology will lead us to a “golden age of research”. Thanks to technology, we are seeing more things that no one has ever seen before. 【答案】36. largest 37. on 38. to protect 39. ways 40. using 41. carefully 42. what 43. them 44. and 45. hopes 【解析】本文主要讲述了科学家利用高科技手段研究和保护帝企鹅的情况。 36. 句意：帝企鹅可以长到 1.2 米高，它们是所有企鹅种类中体型最大的。根据“of all the penguin kinds”可知，此处是在所有企鹅种类中作比较，要用形容词的最高级形式，large的最高级为largest，故填largest。 37. 句意：2022 年，它们被列为濒危动物，因为它们赖以生存的南极海冰正变得越来越小。根据“the Antarctic sea ice that they live...” 可知，帝企鹅生活在南极海冰之上，live on意为“生活在……上面”，故填on。 38. 句意：现在科学家们正利用高科技追踪它们，学习更多保护它们的方法。此处是“疑问词+不定式”的结构，在句中作宾语，how to do sth.意为“如何做某事”，故填to protect。 39. 句意：研究人员能够做到这一点的方法之一是查看来自地球上方卫星拍摄的照片。one of后接可数名词的复数形式，意为“……之一”，way的复数为ways，故填ways。 40. 句意：即使使用卫星，统计不同群体中有多少企鹅也非常困难。分析句子结构可知，句中已有谓语动词 is，此处应用非谓语动词形式，主语it指代的是统计企鹅数量这件事，与use之间是主动关系，所以用现在分词作状语，故填using。 41. 句意：科学家们可以通过仔细观察该地区的天气来改进种群数量的估计。分析句子可知，此处需要用副词来修饰动词watching，careful的副词形式为carefully，意为“仔细地”，故填carefully。 42. 句意：如果科学家们知道拍摄照片时的天气状况，他们就能估计出照片中有多少企鹅。根据“scientists know...the weather was like”可知，询问天气状况的固定表达为“What’s the weather like”，此处是宾语从句，要用陈述语序，所以用what引导宾语从句，故填what。 43. 句意：科学家们还可以通过给企鹅贴上特殊的电子标签来观察它们的活动。动词giving后接人称代词的宾格形式作宾语，they的宾格为them，代指前文的penguins，故填them。 44. 句意：一个机器人携带着扫描仪，并且它可以读取标签上的信息。分析句子结构可知，前半句和后半句之间是顺承关系，应用并列连词and连接，故填and。 45. 句意：企鹅研究人员之一丹尼尔希望这项技术能带领我们进入一个 “研究的黄金时代”。根据全文语境可知，该句为一般现在时，主语Daniel是第三人称单数，谓语动词用第三人称单数形式形式，故填hopes。 第四节、书面表达（15分） 如今，很多野生动物濒临灭绝，假如你是苏珊，英语老师要求你在明天的英语课上，以“Let’s Protect the Endangered Animals!”为主题进行英语演讲，号召大家保护这些动物。请你根据下面的信息，用英语准备一篇演讲稿 要求：1. 演讲稿要包括以下给出的所有提示，可适当拓展； 1.

It’s my great honour to stand here and give a speech today! __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文1 Let’s Protect the Endangered Animals     Hello, everyone. It’s my great honour to stand here and give a speech today! Nowadays, many wild animals are endangered. Some are even dying out. For example, pandas and tigers are disappearing rapidly. This is alarming because animals are important to our ecosystem.     There are two main reasons. First, people cut down forests, so animals lose their homes. Second, some hunt animals for fur or food.     We must take action! We should build more nature reserves to protect habitats. Also, never buy products made from endangered animals. Finally, tell others about animal protection.     Let’s work together to save these animals. Remember: every small action counts! Thank you! 例文2 Hello, everyone. It’s my great honour to stand here and give a speech today! Now many kinds of endangered animals are becoming fewer and fewer. Some are even dying out. They are in great danger. Why is this happening? First, people cut down many trees, so animals lose their homes. Second, some people hunt animals for money. They kill them for their fur or meat. What’s more, pollution makes their living conditions worse. Animals are our friends. We can’t live without them. We must do something to help. We should stop killing animals and protect nature reserves. We mustn’t buy things made of animals. We can also plant more trees and tell others to love animals. Let’s try our best to protect endangered animals. I believe they will live in peace with us. Thank you for listening!

But there is one kind of tiger you might never see—the South China Tiger. It is one of the most endangered (濒危的) animals in the world. “Endangered” means there are very, very few of them left alive in the wild. Long ago, thousands of these beautiful tigers lived in the mountains and forests of south China. They had bright orange fur with dark black stripes. They were strong and skilled hunters (捕猎者). But now, scientists think there are almost no South China Tigers living freely in nature. What happened? First, people cut down many forests to build farms and cities. This destroyed the tigers’ habitat—the natural place where an animal lives. Without a forest, tigers lose their home and their food. Second, some people hunted tigers for their fur or for medicine. This made the number of tigers drop quickly. Is there any hope for the South China Tiger? Yes! China is trying very hard to save them. Special places called reserves (保护区) are built. A reserve is a protected area where animals can live safely. Some tigers live in zoos, and scientists hope to teach their babies how to live in the wild again. It is a difficult plan, but people are working on it. We must remember: Every animal is important in our world. Losing the South China Tiger would not just mean losing a big cat. It would mean losing a part of China’s natural beauty forever. Protecting them is protecting our future. 11. What is TRUE about the South China Tiger in the past? A. They lived in zoos around the world. B. They had yellow fur with white stripes. C. They were good at hunting in forests. D. They were found in many countries. 12. In Paragraph 3, the underlined word “destroyed” most probably means ________. A. 建造 B. 破坏 C. 描绘 D. 寻找 13. Which is NOT a reason for the South China Tiger becoming endangered? A. Losing their habitat because of building. B. Being hunted by people for different uses. C. Living in reserves that are too small. D. Not having enough food and home. 14. What can we infer from Paragraph 4? A. All South China Tigers now live in the wild freely. B. It is an easy job to save the South China Tiger. C. People have given up trying to protect this tiger. D. China is taking action to help the tigers survive. 15. What is the main purpose of this passage? A. To tell people how to hunt South China Tiger. B. To describe the life of South China Tiger in a zoo. C. To explain why and how to save the South China Tiger. D. To ask more people to visit forests of south China. B 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 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. 16. What does the underlined word “them” in paragraph 1 mean? A. Cities. B. Wetlands. C. Waterbirds. D. Mangroves. 17. What can we learn from paragraph 2? A. Mangroves are unsafe for baby birds. B. Mangroves can protect tall buildings from storms. C. Mangroves can produce a lot of CO₂ and dirty water. D. Mangroves are good for not only nature but also people. 18. Why does the writer talk about black-faced spoonbills’ population? A. To introduce modern AI technology. B. To tell readers what the birds look like. C. To explain why endangered birds are important. D. To show the success of protecting birds’ homes. 19. What can we infer (推断) from the last paragraph? A. Students can do research on mangrove protection in the IMC. B. The IMC guides cities to work better together and protect nature. C. The IMC mainly helps the two cities to build more mangrove forests. D. People don’t need to worry about wetland problems because of the IMC. 20. What is the main idea of the passage? A. Mangroves provide safe homes for waterbirds. B. The IMC in Shenzhen helps protect the wetlands. C. There are more black-faced spoonbills in Shenzhen. D. The two cities protect the mangrove wetlands together. C More researchers are turning to artificial intelligence (AI) to monitor the environment and support endangered creatures. Unlike traditional methods that can damage the environment or require considerable time and physical work, AI has the ability to quickly and effectively deal with large quantities of data (数据). Creatures are disappearing at a speed thousands of times faster than that millions of years ago, with one million creatures endangered. The United Nations set a goal in 2020 to safeguard at least 30% of Earth’s land and oceans by the end of 2030. AI is “imperfect” but could make important discoveries faster and earlier, says Nicolas Miailhe, founder of The Future Society, an organization that aims to better manage AI. “We need skilled humans to design AI models and check and collect data.” A type of AI model called a convolutional neural network (CNN) has been developed to recognize bird sounds. The CNN is able to pick out 75 kinds of the birds the researchers have. “Our results prove that AI is ready for recognizing creatures in the wild from sound,” says Maller, the team leader. “All that is needed now is more training data collected by humans.” Besides monitoring creatures in real time, AI can be used to model the impacts of human activities on the environment and rebuild historical changes. Researchers have used AI to discover how a century’s environmental damage in a river has led to creature loss. Although it is well-known that human activities have resulted in creature loss in rivers and lakes, little is known about which activities have the largest impact. “AI will do soon,” says Luisa Orsini, a researcher from the University of Birmingham. 21. Which is true about AI used in monitoring the environment? A. It is being in fashion. B. It will do the job more quickly and effectively. C. Considerable time and physical work are needed. D. It does less harm to the environment than the traditional methods. 22. What can we infer from Nicolas Miailhe’s and Muller’s words? A. AI’s ability is greater than human’s. B. AI’s ability is not as great as people think. C. AI’s ability is much greater than people imagine. D. AI’s ability cannot be achieved without human supports. 23. What does the underlined word “impacts” in Paragraph 4 mean? A. Effects. B. Choices. C. Benefits. D. Purposes. 24. What is the structure of the article? (P=paragraph) A. ①/②③④/⑤ B. ①/②③/④/⑤ C. ①②/③④/⑤ D. ①/②③④⑤ 25. What is the best title for the passage? A. Why Researchers has Turned to AI. B. How AI Can Help Save Endangered Creatures. C. Why AI Can Help with Environmental Protection. D. How Scientific Researches have Been Changed by AI. 第二节 短文填空 以下是一则短文, 请阅读短文, 并从下列六个句子中选择五个还原到原文中, 使原文的意思完整、连贯。并在答题卡上将相应的字母编号涂黑。（共5 小题, 每小题1分） Today, a kind of animal is an endangered species (物种). This means there are very few animals of that kind left on Earth. The animals could face extinction. 26 When a type of animal is extinct, it is gone forever. One problem for animals is that their living places are sometimes destroyed by humans. As human populations increase, more and more space is needed. Building houses for people to live in forces animals to leave their natural homes. Trees are cut down to make room for homes and businesses. Swamps (沼泽) are filled in so that neighborhoods can expand (扩展). The living places are destroyed. The animals have nowhere else to go. 27 Humans must stop the extinction of animals because of the loss of their living places. We have to learn more about animal populations when considering building things. Other choices may not be so convenient. 28 Better planning can make a difference. It is still possible to keep so many kinds of animals for future children to enjoy. Another major problem is overhunting by humans. 29 The governments of countries around the world must agree on laws about protecting animals. Some animals may have large enough populations so hunting will not put them in danger. Others must be protected. 30 Some organizations are working hard to create living places for them. Breeding (繁殖) programs are helping animal populations increase. We all have to know the problem and think before we act. The things we do can have an effect on more than just ourselves. A. This is a worldwide problem. B. Extinction is when all the animals of that kind die. C. However, they can be helpful to the lovely animals. D. It is important for animals to have enough food to eat. E. There is still hope for animals on the endangered species list. F. Without a living place, the number of animals begins to go down. 第三节 信息匹配（共 5小题, 每小题1分） 配对阅读。左栏是五位学生的需求，右栏是七条关于动物的信息，请为每位学生找到合适的信息。选项中有两项为多余项。 31 Lin Mei hears that tigers are in danger now. She wants to know more about them. 32 Linda wants to find somewhere to see whales and play with them. 33 Tony wants to do something to help save animals in danger. 34 Alice wants to know if (是否) whales are in danger or not. 35 Wei Fang wants to know why animals are in danger. A. You can see whales in the water around Tonga (汤加) between August and October. Welcome to Tonga to play with the whales. B. Many kinds of animals are endangered when the number of their adult (成年的) ones is under 2,500. Very endangered animals may have no more than 50 adult members. C. You can help save endangered animals. Try to call for more people to keep them safe or give your money to the WWF. D. There’s good news. The number of tigers living in the wild rises to about 5,500. However, tigers lived in about 25 countries many years ago, but today they only live in 13 countries. E. The WWF chose the panda as its symbol. It works in more than 100 countries around the world to help with the diversity (多样性) of life. F. Why do animals become endangered? It’s because of people’s activities, like cutting down trees and killing. Then they don’t have many places to live or food to eat. G. There are many kinds of whales in the sea. Not all of them are endangered. But there are 11 kinds on the endangered list. 第二部分 非选择题（25分） III. 语法填空（10分） 阅读下面短文, 在空白处填入一个适当的单词或括号内单词的正确形式。 With the development of science and technology, we have learned a lot about animals. Emperor penguins can grow up to 1.2 meters tall, and they are the 36 (large) of all the penguin kinds. In 2022, they were listed as endangered animals because the Antarctic sea ice that they live 37 is becoming smaller and smaller. Now scientists are using high technology to follow them and learn more about how 38 (protect) them. One of the 39 (way) researchers are able to do this is by looking at pictures taken by satellites above the Earth. Large groups of emperor penguins can be seen from space. When scientists first started using satellites to look at the penguins, there were only 28 groups. So far, scientists have discovered 66 groups. Even 40 (use) satellites, it is so difficult to count how many penguins live in different groups. Scientists can improve population estimates (估计) by watching the area’s weather 41 (careful). Measuring the wind speed and temperature can help predict if the penguins gather closely together or spread apart across the ice. If scientists know 42 the weather was like when the pictures were taken, they can estimate how many penguins are pictured. Scientists can also watch penguins' movements by giving 43 (they) special electronic tags. A scanner is carried by a robot, 44 it can read information on the tags. The robot also uses AI to recognize the penguins. It moves very slowly so that it doesn’t make the birds stressed. Daniel, one of the penguin researchers, 45 (hope) the technology will lead us to a “golden age of research”. Thanks to technology, we are seeing more things that no one has ever seen before. 第四节、书面表达（15分） 如今，很多野生动物濒临灭绝，假如你是苏珊，英语老师要求你在明天的英语课上，以“Let’s Protect the Endangered Animals!”为主题进行英语演讲，号召大家保护这些动物。请你根据下面的信息，用英语准备一篇演讲稿 要求：1. 演讲稿要包括以下给出的所有提示，可适当拓展； 1.
