Plastic pollution, overfishing and ocean acidification are threatening marine ecosystems. The Great Pacific Garbage Patch, a collection of marine debris in the North Pacific Ocean, is now estimated to be twice the size of Texas. Plastic waste is particularly harmful to marine life. Sea turtles mistake plastic bags for jellyfish. Seabirds ingest plastic fragments, filling their stomachs and causing starvation. Microplastics, tiny particles of plastic, have been found in the deepest parts of the ocean and in the bodies of fish that we eat. Overfishing is another major problem. Many fish populations have been depleted to unsustainable levels. The loss of top predators like sharks disrupts the balance of marine ecosystems. Bycatch — the unintentional capture of non-target species — also contributes to the decline of marine life. Ocean acidification, caused by the absorption of carbon dioxide, is making the oceans more acidic. This affects the ability of marine organisms, particularly shellfish and coral reefs, to build their shells and skeletons. Coral reefs, which support 25% of marine life, are especially vulnerable. Addressing these challenges requires international cooperation. Reducing plastic use, establishing marine protected areas, and promoting sustainable fishing practices are all essential steps. The health of our oceans is directly linked to our own survival. ( ) 36. What is the Great Pacific Garbage Patch? A. A collection of marine debris in the North Pacific Ocean.B. A type of fish found in the Pacific.C. A protected marine area.D. A coral reef in the Pacific. ( ) 37. How do microplastics affect humans? A. They cause skin irritation.B. They have been found in fish that humans eat.C. They are harmless to humans.D. They only affect marine animals. ( ) 38. What is bycatch? A. The target species of fishing.B. The intentional capture of fish.C. The unintentional capture of non-target species.D. The breeding of fish in captivity. ( ) 39. How does ocean acidification affect coral reefs? A. It helps them grow faster.B. It has no effect on coral reefs.C. It affects their ability to build skeletons.D. It makes them stronger. ( ) 40. What is the main message of this passage? A. The oceans are healthy and thriving.B. The oceans face multiple threats and require urgent action.C. Only plastic pollution affects the oceans.D. Overfishing is not a serious problem. B Rewilding is a conservation strategy that aims to restore natural processes and ecosystems to a state that is self-sustaining and resilient. Unlike traditional conservation, which often focuses on protecting individual species, rewilding seeks to bring back the ecological processes that support biodiversity. One of the key elements of rewilding is the reintroduction of keystone species. These are species that have a disproportionately large effect on their environment. Wolves, beavers and large herbivores like bison are all examples of keystone species. Their presence can trigger a cascade of positive ecological changes. The reintroduction of wolves to Yellowstone National Park is a well-known example. Wolves controlled the elk population, which allowed vegetation to recover. This led to the return of birds, beavers and fish. The entire ecosystem became more diverse and resilient. This shows how a single species can help restore the balance of a whole ecosystem. Rewilding also involves allowing natural processes to operate without human intervention. This means letting rivers meander, allowing forests to regenerate naturally, and letting wildfires burn when they are not a threat to human communities. By stepping back, we can let nature heal itself. However, rewilding is not without controversy. Some people worry about the reintroduction of predators, which can threaten livestock and human safety. There are also concerns about the cost and the long-term commitment required. Despite these challenges, rewilding offers a hopeful vision for the future of conservation. ( ) 41. What is rewilding? A. Protecting individual species.B. Restoring natural processes and ecosystems.C. Creating artificial habitats for animals.D. Eliminating predators from ecosystems. ( ) 42. What is a keystone species? A. A species that is most abundant in an ecosystem.B. A species that has a disproportionately large effect on its environment.C. A species that is endangered.D. A species that only lives in a specific area. ( ) 43. How did the reintroduction of wolves affect Yellowstone? A. It caused the elk population to grow uncontrollably.B. It had no effect on the ecosystem.C. It helped restore the balance of the ecosystem.D. It led to the extinction of other species. ( ) 44. What is one controversy associated with rewilding? A. It is too expensive.B. It is always successful.C. The reintroduction of predators can threaten livestock and human safety.D. It requires no human intervention. ( ) 45. What is the writer’s attitude towards rewilding? A. Highly critical.B. Neutral.C. Optimistic but acknowledges challenges.D. Completely dismissive. C Glaciers are among the most powerful symbols of climate change. These massive rivers of ice are retreating at an unprecedented rate, with devastating consequences for ecosystems and human communities. As glaciers melt, they contribute to sea-level rise and affect the availability of freshwater for billions of people. The Himalayas, often called the “Third Pole,” hold the largest amount of ice outside the polar regions. The region’s glaciers feed rivers that provide water to over 1.5 billion people in South Asia. However, these glaciers are melting faster than ever before. A study published in 2023 found that Himalayan glaciers have lost 65% of their ice since 1970. In the Andes, glaciers are also retreating rapidly. Communities that depend on glacial meltwater for agriculture and drinking water are facing water shortages. In Peru, some communities have already experienced conflicts over water resources. As the glaciers disappear, entire ecosystems and ways of life are threatened. The loss of glaciers also affects biodiversity. Species that have adapted to life in glacial environments are losing their habitats. Mountain ecosystems are particularly vulnerable because species have limited space to migrate to higher altitudes. The extinction of species that depend on glacial environments is a real possibility. Reducing greenhouse gas emissions is the only way to slow the melting of glaciers. However, even if emissions are reduced, some glacier loss is already inevitable. We must adapt to these changes while working to preserve what remains of these essential natural resources. ( ) 46. What is the main cause of glacier melting? A. Natural climate cycles.B. Climate change.C. Volcanic activity.D. Ocean currents. ( ) 47. Why are the Himalayas called the “Third Pole”? A. Because they are the third highest mountain range.B. Because they hold the largest amount of ice outside the polar regions.C. Because they are the third oldest mountain range.D. Because they are located in three countries. ( ) 48. How has the Himalayan glacier ice volume changed since 1970? A. It has increased by 65%.B. It has remained stable.C. It has lost 65% of its ice.D. It has lost 35% of its ice. ( ) 49. What problem is the loss of glacial meltwater causing in the Andes? A. Increased tourism.B. Water shortages and conflicts.C. More agriculture.D. Higher incomes for farmers. ( ) 50. What is the writer’s main message about glacier melting? A. It is a natural and unavoidable process.B. It is caused by climate change and requires urgent action.C. It only affects polar regions.D. It has no effect on human communities. D The concept of the Anthropocene has gained increasing attention among scientists and policymakers. This proposed geological epoch recognizes the profound impact that human activities have had on the Earth’s ecosystems. From the Industrial Revolution to the present day, human actions have transformed the planet in ways that are comparable to major natural events. One of the most visible signs of the Anthropocene is the widespread presence of plastic. Plastic has been found in the deepest ocean trenches, on the highest mountains, and even in the air we breathe. The accumulation of plastic waste is a lasting legacy of our consumption patterns. Future geologists will be able to identify our era by the layer of plastic in the Earth’s strata. Climate change is another defining feature of the Anthropocene. The increase in greenhouse gas emissions has led to rising temperatures, melting ice caps and more extreme weather events. These changes are altering the natural world in ways that will persist for thousands of years. However, the Anthropocene is not just a story of destruction. It is also a story of awareness and action. The recognition of our impact has led to the development of renewable energy technologies, conservation efforts and international agreements like the Paris Accord. The future of the Anthropocene depends on the choices we make today. We have the power to either continue on a destructive path or to build a more sustainable future. ( ) 51. What is the Anthropocene? A. A geological epoch defined by human impact on the Earth.B. A type of fossil fuel.C. A climate change denial theory.D. A natural geological period. ( ) 52. Why is plastic mentioned as a sign of the Anthropocene? A. Because it is a valuable resource.B. Because it has become widespread and will leave a lasting mark.C. Because it is biodegradable.D. Because it is only found in oceans. ( ) 53. What is one defining feature of the Anthropocene? A. Natural disasters.B. Climate change caused by greenhouse gas emissions.C. The extinction of dinosaurs.D. The Ice Age. ( ) 54. What positive development is associated with the Anthropocene? A. Increased deforestation.B. The development of renewable energy and conservation efforts.C. More plastic production.D. Ignoring environmental problems. ( ) 55. What is the writer’s overall message about the Anthropocene? A. It is unavoidable and there is nothing we can do.B. It is a destructive era, but we have the power to choose a sustainable future.C. It is only about destruction.D. It is not a real concept. 五、用所给词的适当形式填空(共5小题；每小题1分，满分5分) 根据句意，用括号内所给单词的正确形式填空。 56. The ________ (pollute) of the river has caused severe damage to the local ecosystem. 57.

Parks, community gardens and green roofs provide essential benefits for both the environment and human well-being. Urban green spaces help reduce air pollution, lower temperatures and provide habitats for wildlife. One of the most significant benefits of green spaces is their ability to absorb carbon dioxide and produce oxygen. Trees and plants act as natural air filters, removing harmful pollutants from the air. This is especially important in cities, where air quality is often poor. A single tree can absorb up to 48 pounds of carbon dioxide per year. Green spaces also help to reduce the urban heat island effect. Cities are often several degrees warmer than surrounding rural areas because of the heat absorbed by concrete and asphalt. Green spaces provide shade and release moisture through evapotranspiration, which cools the air. This can reduce the need for air conditioning and lower energy consumption. In addition to environmental benefits, urban green spaces also have social and psychological benefits. They provide places for recreation, relaxation and social interaction. Studies have shown that access to green spaces can reduce stress, improve mental health and increase physical activity. However, green spaces in cities often face threats from development. It is important for city planners to prioritize the creation and maintenance of green spaces. Community involvement is also crucial. When residents take part in gardening and conservation activities, they develop a stronger connection to their neighbourhood and a greater appreciation for the environment. 71. What are the environmental benefits of urban green spaces? (Give two examples) 72. How do green spaces help reduce the urban heat island effect? 73. What social and psychological benefits do green spaces provide? 74. Why is community involvement important for urban green spaces? 75. According to the passage, what is one challenge that urban green spaces face? 八、短文填空(共10小题；每小题1.5分，满分15分) 阅读下面短文，在空白处填入一个适当的单词或括号内所给单词的正确形式。 In the heart of Africa, the Okavango Delta is one of the world’s most [76] ______ (remark) wetland ecosystems.
