The natural world includes forests, oceans, deserts, mountains and all the living things that inhabit them. Each part of the natural world plays an important role in maintaining the balance of life on Earth. Forests are often called the “lungs of the Earth” because they absorb carbon dioxide and produce oxygen. They are home to more than half of the world’s land-based species. However, forests are being cut down at an alarming rate for timber and to make space for agriculture. This not only threatens biodiversity but also contributes to climate change. Oceans cover about 70% of the Earth’s surface. They regulate the climate, provide food and support a huge variety of marine life. But oceans are suffering from plastic pollution, overfishing and warming temperatures. Coral reefs, which are often called the “rainforests of the sea”, are dying because of rising sea temperatures and ocean acidification. It is our responsibility to protect the natural world. By reducing waste, conserving water and supporting conservation projects, we can help preserve these precious ecosystems for future generations. ( ) 26. Why are forests called the “lungs of the Earth”? A. They produce oxygen and absorb carbon dioxide.B. They are home to many animals.C. They provide timber.D. They cover a large area. ( ) 27. What percentage of the Earth’s surface do oceans cover? A. About 30%.B. About 50%.C. About 70%.D. About 90%. ( ) 28. What is threatening coral reefs? A. Overfishing.B. Rising sea temperatures and ocean acidification.C. Plastic pollution only.D. Deforestation. ( ) 29. What can we do to protect the natural world? A. Cut down more trees.B. Reduce waste and conserve water.C. Increase pollution.D. Use more plastic. ( ) 30. What is the main idea of this passage? A. The natural world is beautiful.B. Forests and oceans are important and need protection.C. Climate change is not a problem.D. We should use more natural resources. B Water is one of the most precious resources on Earth. It covers about 71% of the planet’s surface, but only 2.5% of it is fresh water. Of this, less than 1% is easily accessible for human use. With a growing global population, water scarcity is becoming an increasingly serious issue. Agriculture uses the largest amount of fresh water — about 70% of global water consumption. Industrial processes also consume a significant amount. In many regions, water is used inefficiently, leading to waste. Climate change is making water availability more unpredictable, with some areas experiencing severe droughts while others face flooding. Water pollution is another major problem. Industrial waste, agricultural runoff and untreated sewage contaminate rivers and lakes. This not only harms aquatic life but also threatens human health. Millions of people around the world lack access to clean drinking water. To address water issues, we need to adopt sustainable practices. Individuals can help by conserving water at home — taking shorter showers, fixing leaks and using water-efficient appliances. Governments and industries must invest in water treatment and recycling technologies. Protecting wetlands and forests also helps maintain water cycles. We all have a role to play in protecting this vital resource. ( ) 31. What percentage of the Earth’s water is fresh water? A. About 1%.B. About 2.5%.C. About 71%.D. About 70%. ( ) 32. Which sector uses the most fresh water? A. Industry.B. Agriculture.C. Household use.D. Tourism. ( ) 33. What is one cause of water pollution mentioned in the passage? A. Climate change.B. Water scarcity.C. Industrial waste and agricultural runoff.D. Overpopulation. ( ) 34. What can individuals do to conserve water? A. Take longer showers.B. Fix leaks and use water-efficient appliances.C. Ignore water waste.D. Use more water. ( ) 35. What is the writer’s purpose in writing this passage? A. To describe the beauty of water.B. To explain the importance of fresh water and how to protect it.C. To complain about water pollution.D. To compare different water sources. C Renewable energy is energy that comes from natural sources that are constantly replenished, such as sunlight, wind, rain, tides and geothermal heat. Unlike fossil fuels, which are finite and produce greenhouse gases, renewable energy offers a clean and sustainable alternative. Solar energy is one of the most widely available renewable sources. Solar panels convert sunlight into electricity. As technology improves, the cost of solar energy has decreased significantly. Many homes and businesses are now installing solar panels to reduce their carbon footprint. Wind energy is another important renewable source. Wind turbines harness the power of the wind to generate electricity. Wind farms can be found both on land and offshore. Some countries, like Denmark, generate a large portion of their electricity from wind power. Hydropower uses the energy of flowing water to generate electricity. Dams are built on rivers to control water flow and produce power. While hydropower is a clean energy source, it can have environmental impacts on river ecosystems. Transitioning to renewable energy is essential for mitigating climate change and reducing pollution. Governments around the world are investing in renewable energy infrastructure and offering incentives for adoption. Individuals can also contribute by choosing green energy options and supporting policies that promote sustainability. ( ) 36. What is renewable energy? A. Energy from fossil fuels.B. Energy from sources that are constantly replenished.C. Energy from nuclear power.D. Energy from non-renewable sources. ( ) 37. How has the cost of solar energy changed? A. It has increased significantly.B. It has decreased significantly.C. It has stayed the same.D. It is very expensive. ( ) 38. What is one advantage of renewable energy? A. It produces greenhouse gases.B. It is a clean and sustainable alternative.C. It is finite.D. It is expensive. ( ) 39. What is a potential disadvantage of hydropower? A. It is not renewable.B. It can have environmental impacts on river ecosystems.C. It produces greenhouse gases.D. It is very expensive. ( ) 40. What is the main idea of this passage? A. Renewable energy is not important.B. We should only use fossil fuels.C. Renewable energy is a clean, sustainable alternative and is essential for the future.D. Only governments can use renewable energy. 四、单词拼写(共5小题；每小题1分，满分5分) 根据句意和首字母或中文提示，写出单词的正确形式。 41. The government is working to r ______ (减少) pollution levels in the city. 42.

It refers to long-term changes in temperature and weather patterns. While natural factors have influenced the climate in the past, the current rapid warming is largely caused by human activities. The main cause of climate change is the burning of fossil fuels like coal, oil and gas. When these fuels are burned, they release greenhouse gases such as carbon dioxide into the atmosphere. These gases trap heat from the sun, causing the Earth’s temperature to rise. This is known as the greenhouse effect. Deforestation also contributes to climate change because trees absorb carbon dioxide. When forests are cut down, this carbon dioxide remains in the atmosphere. Climate change has many effects. Rising temperatures are causing glaciers and ice caps to melt. This leads to rising sea levels, which threaten coastal communities. Weather patterns are becoming more extreme, with more frequent and severe storms, droughts and floods. Agriculture is affected as crop yields decline in many regions. Biodiversity is also threatened as species struggle to adapt to changing conditions. To address climate change, we need to reduce greenhouse gas emissions. This can be done by transitioning to renewable energy sources, improving energy efficiency, and protecting forests. Individuals can also contribute by reducing their carbon footprint: walking or cycling instead of driving, using less energy at home, and consuming less meat and dairy products. International cooperation is essential to meet this global challenge. Understanding Climate Change Aspect Key Information Definition Long-term changes in temperature and weather [71] ______.

These problems harm wildlife and endanger the health of our planet. Protecting nature is important because it provides us with clean air, water and food. It also supports biodiversity and helps regulate the climate. Without a healthy environment, life on Earth would be impossible. We can all take action to protect nature. First, we can reduce waste and recycle more. Second, we can save water and electricity at home. Third, we can plant trees and support conservation projects. Every small effort counts. Let’s work together to protect our beautiful planet for future generations. 学科网（北京）股份有限公司 $
