When the visitors took a closer look, they found these colorful fish were actually robots! This amazing scene happened at the World Digital Education Exhibition in Wuhan. Scientists from Wuhan University spent much time developing these red, yellow and blue robotic fish. The fish are about 53 centimeters long. The joints (关节) in their heads and tails are designed in a special way, allowing them to swim smoothly and naturally. ________ This is the fruit of the latest development of bionic engineering (仿生工程). It cleverly mixes nature and technology to create new inventions. James Crabbe, a scientist at the University of Oxford, explained the bionic fish could help researchers learn more about how fish behave. Take fish swarming for an example: it is a way for fish to swim in large groups to stay safe. In this way, they can also save energy and find food more easily. Studying fish swarming helps scientists understand how fish live and how the environment influences them. To scare away dangerous animals, the bionic fish show different colors with the lights built into their bodies. Inside each fish, there is a sender to give out signals (信号). When meeting things, the signals are sent back quickly and caught by the receiver in the body. In this way, the bionic fish can “see” and stay away from things in their way. Now they are being used to study the Yangtze River’s water quality and play a key role in protecting our living environment. ( ) 31. How did the visitors probably feel when seeing the robotic fish in paragraph 1? A. Happy. B. Surprised. C. Moved. D. Comfortable. ( ) 32. Which of the following can be put in “________” in Paragraph 2? A. They act almost like real ones. B. Scientists are interested in them. C. It is not difficult to make them. D. Visitors can easily buy them now. ( ) 33. What does the underlined word “swarming” mean in Paragraph 3? A. Swimming quickly. B. Swimming alone. C. Swimming smoothly. D. Swimming together. ( ) 34. What is the reason for the bionic fish to “see” things? A. They have some lights inside. B. They can see with their eyes. C. They have a sender and receiver. D. They show different colors. ( ) 35. What’s the best title for the passage? A. Amazing World Exhibition B. Hard-working Scientists C. Interesting Studies of Fish D. Helpful Robotic Fish 【主旨大意】 本文是一篇说明文，介绍武汉大学生研发的仿生机器鱼：外观如真鱼，通过仿生工程设计实现自然游动，可帮助研究鱼类行为、监测水质，体现科技与自然的结合。 31.B【解析】第一段提到：“these colorful fish were actually robots! This amazing scene”，“amazing”（令人惊奇的）表明游客会感到惊讶，Surprised符合。 32.A【解析】第二段前半部分描述机器鱼的关节设计让它们“swim smoothly and naturally”（游动流畅自然），后文提到“仿生工程将自然与科技结合”，空格处应衔接“机器鱼接近真实鱼类”的内容。 33.D【解析】第三段解释“fish swarming”是“swim in large groups”（成群游动），说明“swarming”意为“一起游动”。 34.C【解析】第四段明确指出：“Inside each fish, there is a sender to give out signals...caught by the receiver in the body. In this way, the bionic fish can ‘see’”，说明“看见”是因为有发送器和接收器。 35.D【解析】文章围绕仿生机器鱼展开，介绍其特点、用途（帮助研究、监测水质），核心是“有用的机器鱼”。 B In the shallow waters of the Pacific Ocean lie coral reefs colored by some algae that live with coral. Coral usually provides nitrogen (氮) to algae, and in return it gets carbon (碳), which gives it energy. In the early 1980s, a huge heat wave turned more than 90 percent of the coral (珊瑚) pale, lifeless white. And it was believed that about 50 percent of reefs with beautiful coral might disappear by 2030. Heat waves warmed up the same Pacific waters in the late 1990s and again in 2015-2016, but scientists noticed that these heat waves didn't influence the reefs as badly as the first. Maybe coral has found a way to adapt (适应). Swimming to cooler waters is not a good choice for coral, for it makes coral easily hurt by the changing climate. But coral is able to adapt. Some coral turns to those algae that can deal well with heat. Other coral can use rows of tiny hairs on its body to “fan” away too much harmful oxygen let out by stressed-out algae. Certain baby coral changes its own metabolism (新陈代谢) in order to fight the warming waters. But all these adaptations can protect themselves only to some degree. After studying and understanding these adaptations, scientists are trying to find ways to help coral fight. If researchers can make coral accept algae that can deal with heat pressure or if they energize genes (基因) that can deal with heat pressure, it will raise the coral’s chance of living through future ocean heat waves. “When I go down to the sea and see a beautiful healthy reef with the colorful coral, I feel this pleasure of being in this underwater world,” a famous biologist says. “It will be really sad to see it dead. But that does drive you to want to use your skills and your love to help fight.” ( ) 36. What can we know from Paragraph 1? A. Coral makes algae more colorful. B. Algae provide room for coral to live in. C. Coral and algae depend on each other. D. Algae produce nitrogen to influence coral. ( ) 37. What does the underlined part “the first” in Paragraph 2 refer to? A. The heat wave in the early 1980s. B. The heat wave in the late 1990s. C. The Pacific waters in 2015-2016. D. The reefs' disappearance by 2030. ( ) 38. What difficulty does coral face? A. It cannot completely adapt to heat waves. B. It cannot change its own metabolism. C. It has no ability to swim to cooler waters. D. It has no ability to drive away harmful oxygen. ( ) 39. What can we infer from the last paragraph? A. It’s necessary to live with coral. B. The ocean has become unhealthy. C. We should try our best to save coral. D. Making a study of the ocean is a must. ( ) 40. Which would be the best title for the text? A. Coral Dies Out. B. Coral Fights Back. C. Coral Breaks Down. D. Coral Comes into Being. 【主旨大意】 本文是一篇说明文，介绍了太平洋珊瑚礁与藻类的共生关系、热浪对珊瑚的影响、珊瑚的自我适应机制，以及科学家为保护珊瑚所做的努力，呼吁人们重视并保护珊瑚生态。 36.C【解析】第一段提到“Coral usually provides nitrogen (氮) to algae, and in return it gets carbon (碳), which gives it energy.”，说明珊瑚为藻类提供氮，藻类为珊瑚提供碳，二者是相互依存的关系。 37.A【解析】第二段先介绍了“20世纪80年代初的热浪导致90%以上的珊瑚变白”，接着提到“90 年代末、2015-2016年的热浪对珊瑚的影响没有第一次那么严重”，因此“the first”指代的是20世纪80年代初的那次热浪。 38.A【解析】第三段提到“But all these adaptations can protect themselves only to some degree.”，说明珊瑚的适应能力有限，无法完全适应热浪，这是它面临的核心困境。 39.C【解析】最后一段引用生物学家的话，表达了对珊瑚死亡的惋惜，以及“用技能和热爱去帮助对抗（珊瑚消亡）”的决心，核心是呼吁尽最大努力拯救珊瑚。 40.B【解析】全文围绕“珊瑚面对热浪威胁，通过自身适应机制对抗生存危机，同时科学家助力保护”展开，核心是珊瑚的“反击”。 C The ocean covers most of our planet, yet we know very little about it. Our ocean is as mysterious as it is beautiful. In fact, we have better maps of Mars than we do of the ocean floor. Why? Exploring (探索) the ocean is a really hard job. There’s a lot of ocean—about 1.4 billion trillion litres (升). That’s 1,400,000,000,000,000,000,000! ★ . One of their most important goals is to learn about coral reefs (珊瑚礁), which are home to lots of sea plants and animals. Do you know that coral is an animal, not a plant? Tiny animals called polyps (珊瑚虫) build the hard part of the coral as a home to live in. They are called “architects” in the ocean. However, many coral reefs around the world are in danger. That’s where a clever method called “coral gardening” comes in—giving reefs a second chance. Here’s how it works in four steps: First, scientists collect small pieces of coral from coral reefs. Then they break them into even smaller ones—tiny pieces grow faster. After that, they place the pieces in lab-controlled or underwater nurseries (苗圃), where tiny pieces are taken good care of. Finally, once strong enough, they are planted onto rock or man-made reefs so that they can grow on their own. A typical example is the L-shaped Reef. Since 1982, scientists have placed old subway cars into the sea. These strange “homes” have created a huge man-made reef. Now, polyps and fish are moving in! To know more about the ocean, a volunteer, Paul Green started the Big Bag Project in 2025. It calls on beach visitors to help collect information on plastics and water temperature through a bag which is connected with an app. Next time you go to the beach, take a bag, pick up some rubbish, and have a closer connection with the ocean. ( ) 41. What does the number in paragraph 1 tell us about the ocean? A. How much salt there is. B. How cold the deep ocean is. C. How large the ocean is. D. How many sea plants there are. ( ) 42. Which of the following can be put in ★ ? A. Some sea animals are making a comeback B. The ocean is full of wonders to be discovered C. But many scientists are taking on this challenge D. So protecting the ocean is everyone’s responsibility ( ) 43. What does the underlined word “architects” mean? A. People who build houses. B. Machines that carry things. C. Workers who collect coral. D. Animals that live in the sea. ( ) 44. In the picture CORAL GARDENING, what is the third step? A. Breaking. B. Nursing. C. Planting. D. Collecting. ( ) 45. What’s the writer’s main purpose in writing this passage? A. To introduce the Big Bag Project. B. To show the hidden beauty of the ocean. C. To teach us how to become an ocean biologist. D. To encourage more people to explore the ocean. 【解析】 【主旨大意】 本文是一篇说明文，介绍了海洋的神秘性和探索难度，以及科学家通过“珊瑚园艺”和公众参与的“Big Bag Project”来研究保护海洋的方法。 41.C【解析】文章第一段指出“There’s a lot of ocean—about 1.4 billion trillion litres.”，直接说明这个数字告诉我们海洋有多大。 42.C【解析】文章第一段提到探索海洋是一项艰难的工作，第二段指出“One of their most important goals is to learn about coral reefs”，科学家们的重要目标是了解珊瑚礁。由此推断，空白处应填入“但是许多科学家正在接受这一挑战”来承上启下。 43.A【解析】文章第四段指出“Tiny animals called polyps build the hard part of the coral as a home to live in. They are called ‘architects’ in the ocean.”，珊瑚虫建造珊瑚的坚硬部分作为居住的家，就像人类建造房屋一样。由此推断，“architects”意为“建造房屋的人”。 44.B【解析】文章第五段介绍了珊瑚园艺的四个步骤，并结合图片，可知步骤为：收集→破碎→育苗→种植。第三步是“place the pieces in lab-controlled or underwater nurseries, where tiny pieces are taken good care of”，即育苗（nursing）。 45.D【解析】文章介绍了探索海洋的困难、科学家的努力以及普通人通过Big Bag Project参与保护海洋的方式。由此推断，作者的主要目的是鼓励更多人探索海洋。 五、任务型阅读(共5小题，每小题2分，共10分) Imagine an underwater camera that could take photos anywhere in the sea. Until now, the use of underwater cameras still has many problems. Some must be connected to power lines and others depend on batteries (电池) that don't last long. Such problems have kept scientists from discovering most of the ocean world. But now researchers have found a way to solve these problems. They’re powering a new camera with sounds-ocean sounds. The camera has two sensors (传感器) at the bottom. Each is made of special materials. When sound travels through the water, it creates shakes of pressure. These cause the sensors’ material to shake and then the special material changes the shaking into electric energy. An electronic instrument stores the energy, which can be compared to a reusable battery. Once the electronic instrument has enough energy, it turns on the camera and takes pictures. Then, it lets the sensors store more sound energy to receive and send the camera’s pictures-as sound-to some underwater microphones or receivers. In this way, the sensors not only power the camera, but also send out the data (数据) carrying its pictures. The sea is noisy. This makes sure there’s a ready power station to use for the new camera. Any sound can power it-whether it is a swimming fish, passing boats, or falling rocks. That underwater receiver picks up the camera’s data and brings the data together and changes it into a picture. And with that, an undersea photo shoot (拍摄) is done. 46. What are the two problems with old underwater cameras? _________________________________________________________________ 47. How many sensors does the new underwater camera have? _________________________________________________________________ 48. What does sound create when it travels through the water? _________________________________________________________________ 49. Besides powering the camera, what else do the sensors do? _________________________________________________________________ 50. Do you like the new underwater camera? Why or why not? _________________________________________________________________ 【主旨大意】 本文主要介绍了一种利用海洋声音供电的新型水下相机。文章首先指出了传统水下相机需要连接电源线或依赖电池、续航时间短等问题，接着重点介绍了新型相机如何通过底部的传感器将声波震动转化为电能，从而实现自主供电并发送图像数据，解决了旧相机的难题。 46. Some must be connected to power lines and others depend on batteries that don’t last long. 【解析】根据文章第一段第三句“Some must be connected to power lines and others depend on batteries that don't last long.”可知，旧式相机要么必须连接电源线，要么依赖不耐用的电池，答案几乎是原文引述。 47. Two. 解析】根据文章第二段第一句“The camera has two sensors at the bottom.”可知，相机有两个传感器，因此答案是原文直接信息。 48. It creates pressure vibrations. 【解析】根据文章第二段第三句“When sound travels through the water, it creates shakes of pressure.”可知，声音在水中传播时会产生压力震动，因此答案是原文直接信息。 49. They also send out the data carrying the camera’s pictures.【解析】根据文章第三段倒数第二句“In this way, the sensors not only power the camera, but also send out the data carrying its pictures.”可知，传感器不仅为相机供电，还发送携带图像的数据，因此答案是原文直接信息。 50. Yes. Because it can be powered by ocean sounds and work anywhere in the sea, which helps scientists discover the ocean world.【解析】此题属于开放性问答，询问是否喜欢这款新相机及原因。结合文章主旨，这款相机解决了旧相机的痛点，有助于探索海洋，因此回答“Yes”并给出合理的理由，答案不唯一，言之有理即可。 六、补全对话(共5小题，每小题2分，共10分) A: Hi, Tom. What are you looking at? B: I’m watching a video about the ocean. 51 A: Why? What’s wrong with the sea? B: Lots of rubbish goes into the ocean. 52 A: That’s terrible. 53 B: First, we should stop throwing rubbish into rivers or seas. A: Right. And we can use fewer plastic bags and plastic bottles. B: 54 We can also tell our friends not to buy products made from sea animals. A: Will small actions really help? B: Sure. If everyone tries their best, the ocean will become cleaner again.

When the visitors took a closer look, they found these colorful fish were actually robots! This amazing scene happened at the World Digital Education Exhibition in Wuhan. Scientists from Wuhan University spent much time developing these red, yellow and blue robotic fish. The fish are about 53 centimeters long. The joints (关节) in their heads and tails are designed in a special way, allowing them to swim smoothly and naturally. ________ This is the fruit of the latest development of bionic engineering (仿生工程). It cleverly mixes nature and technology to create new inventions. James Crabbe, a scientist at the University of Oxford, explained the bionic fish could help researchers learn more about how fish behave. Take fish swarming for an example: it is a way for fish to swim in large groups to stay safe. In this way, they can also save energy and find food more easily. Studying fish swarming helps scientists understand how fish live and how the environment influences them. To scare away dangerous animals, the bionic fish show different colors with the lights built into their bodies. Inside each fish, there is a sender to give out signals (信号). When meeting things, the signals are sent back quickly and caught by the receiver in the body. In this way, the bionic fish can “see” and stay away from things in their way. Now they are being used to study the Yangtze River’s water quality and play a key role in protecting our living environment. ( ) 31. How did the visitors probably feel when seeing the robotic fish in paragraph 1? A. Happy. B. Surprised. C. Moved. D. Comfortable. ( ) 32. Which of the following can be put in “________” in Paragraph 2? A. They act almost like real ones. B. Scientists are interested in them. C. It is not difficult to make them. D. Visitors can easily buy them now. ( ) 33. What does the underlined word “swarming” mean in Paragraph 3? A. Swimming quickly. B. Swimming alone. C. Swimming smoothly. D. Swimming together. ( ) 34. What is the reason for the bionic fish to “see” things? A. They have some lights inside. B. They can see with their eyes. C. They have a sender and receiver. D. They show different colors. ( ) 35. What’s the best title for the passage? A. Amazing World Exhibition B. Hard-working Scientists C. Interesting Studies of Fish D. Helpful Robotic Fish B In the shallow waters of the Pacific Ocean lie coral reefs colored by some algae that live with coral. Coral usually provides nitrogen (氮) to algae, and in return it gets carbon (碳), which gives it energy. In the early 1980s, a huge heat wave turned more than 90 percent of the coral (珊瑚) pale, lifeless white. And it was believed that about 50 percent of reefs with beautiful coral might disappear by 2030. Heat waves warmed up the same Pacific waters in the late 1990s and again in 2015-2016, but scientists noticed that these heat waves didn't influence the reefs as badly as the first. Maybe coral has found a way to adapt (适应). Swimming to cooler waters is not a good choice for coral, for it makes coral easily hurt by the changing climate. But coral is able to adapt. Some coral turns to those algae that can deal well with heat. Other coral can use rows of tiny hairs on its body to “fan” away too much harmful oxygen let out by stressed-out algae. Certain baby coral changes its own metabolism (新陈代谢) in order to fight the warming waters. But all these adaptations can protect themselves only to some degree. After studying and understanding these adaptations, scientists are trying to find ways to help coral fight. If researchers can make coral accept algae that can deal with heat pressure or if they energize genes (基因) that can deal with heat pressure, it will raise the coral’s chance of living through future ocean heat waves. “When I go down to the sea and see a beautiful healthy reef with the colorful coral, I feel this pleasure of being in this underwater world,” a famous biologist says. “It will be really sad to see it dead. But that does drive you to want to use your skills and your love to help fight.” ( ) 36. What can we know from Paragraph 1? A. Coral makes algae more colorful. B. Algae provide room for coral to live in. C. Coral and algae depend on each other. D. Algae produce nitrogen to influence coral. ( ) 37. What does the underlined part “the first” in Paragraph 2 refer to? A. The heat wave in the early 1980s. B. The heat wave in the late 1990s. C. The Pacific waters in 2015-2016. D. The reefs' disappearance by 2030. ( ) 38. What difficulty does coral face? A. It cannot completely adapt to heat waves. B. It cannot change its own metabolism. C. It has no ability to swim to cooler waters. D. It has no ability to drive away harmful oxygen. ( ) 39. What can we infer from the last paragraph? A. It’s necessary to live with coral. B. The ocean has become unhealthy. C. We should try our best to save coral. D. Making a study of the ocean is a must. ( ) 40. Which would be the best title for the text? A. Coral Dies Out. B. Coral Fights Back. C. Coral Breaks Down. D. Coral Comes into Being. C The ocean covers most of our planet, yet we know very little about it. Our ocean is as mysterious as it is beautiful. In fact, we have better maps of Mars than we do of the ocean floor. Why? Exploring (探索) the ocean is a really hard job. There’s a lot of ocean—about 1.4 billion trillion litres (升). That’s 1,400,000,000,000,000,000,000! ★ . One of their most important goals is to learn about coral reefs (珊瑚礁), which are home to lots of sea plants and animals. Do you know that coral is an animal, not a plant? Tiny animals called polyps (珊瑚虫) build the hard part of the coral as a home to live in. They are called “architects” in the ocean. However, many coral reefs around the world are in danger. That’s where a clever method called “coral gardening” comes in—giving reefs a second chance. Here’s how it works in four steps: First, scientists collect small pieces of coral from coral reefs. Then they break them into even smaller ones—tiny pieces grow faster. After that, they place the pieces in lab-controlled or underwater nurseries (苗圃), where tiny pieces are taken good care of. Finally, once strong enough, they are planted onto rock or man-made reefs so that they can grow on their own. A typical example is the L-shaped Reef. Since 1982, scientists have placed old subway cars into the sea. These strange “homes” have created a huge man-made reef. Now, polyps and fish are moving in! To know more about the ocean, a volunteer, Paul Green started the Big Bag Project in 2025. It calls on beach visitors to help collect information on plastics and water temperature through a bag which is connected with an app. Next time you go to the beach, take a bag, pick up some rubbish, and have a closer connection with the ocean. ( ) 41. What does the number in paragraph 1 tell us about the ocean? A. How much salt there is. B. How cold the deep ocean is. C. How large the ocean is. D. How many sea plants there are. ( ) 42. Which of the following can be put in ★ ? A. Some sea animals are making a comeback B. The ocean is full of wonders to be discovered C. But many scientists are taking on this challenge D. So protecting the ocean is everyone’s responsibility ( ) 43. What does the underlined word “architects” mean? A. People who build houses. B. Machines that carry things. C. Workers who collect coral. D. Animals that live in the sea. ( ) 44. In the picture CORAL GARDENING, what is the third step? A. Breaking. B. Nursing. C. Planting. D. Collecting. ( ) 45. What’s the writer’s main purpose in writing this passage? A. To introduce the Big Bag Project. B. To show the hidden beauty of the ocean. C. To teach us how to become an ocean biologist. D. To encourage more people to explore the ocean. 五、任务型阅读(共5小题，每小题2分，共10分) Imagine an underwater camera that could take photos anywhere in the sea. Until now, the use of underwater cameras still has many problems. Some must be connected to power lines and others depend on batteries (电池) that don't last long. Such problems have kept scientists from discovering most of the ocean world. But now researchers have found a way to solve these problems. They’re powering a new camera with sounds-ocean sounds. The camera has two sensors (传感器) at the bottom. Each is made of special materials. When sound travels through the water, it creates shakes of pressure. These cause the sensors’ material to shake and then the special material changes the shaking into electric energy. An electronic instrument stores the energy, which can be compared to a reusable battery. Once the electronic instrument has enough energy, it turns on the camera and takes pictures. Then, it lets the sensors store more sound energy to receive and send the camera’s pictures-as sound-to some underwater microphones or receivers. In this way, the sensors not only power the camera, but also send out the data (数据) carrying its pictures. The sea is noisy. This makes sure there’s a ready power station to use for the new camera. Any sound can power it-whether it is a swimming fish, passing boats, or falling rocks. That underwater receiver picks up the camera’s data and brings the data together and changes it into a picture. And with that, an undersea photo shoot (拍摄) is done. 46. What are the two problems with old underwater cameras? _________________________________________________________________ 47. How many sensors does the new underwater camera have? _________________________________________________________________ 48. What does sound create when it travels through the water? _________________________________________________________________ 49. Besides powering the camera, what else do the sensors do? _________________________________________________________________ 50. Do you like the new underwater camera? Why or why not? _________________________________________________________________ 六、补全对话(共5小题，每小题2分，共10分) A: Hi, Tom. What are you looking at? B: I’m watching a video about the ocean. 51 A: Why?
