Before the trip, I thought farms only grew crops and raised animals separately. But this farm taught me what “ecological balance” really means. When I arrived, the farmer, Uncle Li, showed me around. He explained that they don’t use chemical fertilizers or pesticides. Instead, they feed crop straw to cows, and use cow dung to fertilize the fields. The leftover cow dung is even turned into biogas for cooking — nothing is wasted. “In the past, we used chemicals to grow more crops, but the soil became hard and the river nearby turned black,” Uncle Li said. “Now we balance resource use, and the farm produces healthier food while protecting the environment.” I helped pick tomatoes and feed the cows that afternoon. The tomatoes tasted sweeter than those in supermarkets, and the cows were calm and healthy. Before leaving, Uncle Li gave me a basket of vegetables. “Small farms like this are the future,” he said. “We don’t need to produce the most food — we need to produce food that’s good for people and the planet.” On the way home, I thought about how our daily choices affect the environment. Buying locally grown, chemical-free food is a small step, but it helps keep the balance of nature. 21. Where did the story take place? A. In a suburban ecological farm. B. In a downtown supermarket. C. In a chemical factory. D. In a city park. 22. What was the writer doing when he visited the farm? A. Selling chemical fertilizers. B. Volunteering and learning about eco-farming. C. Raising cows for profit. D. Cleaning up the black river. 23. Why did Uncle Li stop using chemical fertilizers? A. Because they were too expensive. B. Because they damaged the soil and river. C. Because the government banned them. D. Because cows refused to eat straw. 24. How does the farm achieve ecological balance? A. By growing as many crops as possible. B. By using leftover materials for multiple purposes. C. By killing all pests with pesticides. D. By selling biogas to nearby villages. 25. What is the main lesson the writer learned? A. Farms should produce the most food to make money. B. Chemical fertilizers help grow sweeter tomatoes. C. Small daily choices can help protect natural balance. D. Supermarket vegetables are healthier than farm-grown ones. B Cities around the world are facing a serious problem: the urban heat island effect. Concrete buildings and asphalt roads absorb heat during the day and release it at night, making city temperatures 3-5℃ higher than surrounding rural areas. To balance urban development and climate regulation, many cities in China have launched “cool city” projects. Shanghai is a leading example. Since 2020, the city has added 1,200 hectares of green space, including rooftop gardens, vertical green walls and pocket parks. Data shows these green areas have reduced average summer temperatures by 1.2℃ in downtown areas. The city also replaced 30% of asphalt roads with permeable pavement (透水路面), which absorbs rainwater and reduces surface heat. Another effective measure is reflective roofing. The city government subsidizes (补贴) residents to paint their rooftops white or light gray. Reflective surfaces reflect up to 80% of sunlight, reducing air conditioning use by 15% in summer. A 2025 report found that Shanghai’s “cool city” projects have cut carbon emissions by 420,000 tons per year — equivalent to planting 23 million trees. Experts say balancing urban growth and environmental protection is not just about adding green space. It also requires smart urban planning: locating industrial zones away from residential areas, limiting high-rise buildings in wind corridors, and promoting public transportation. “Cities don’t have to choose between development and a comfortable climate,” said Dr. Wang, an urban planning expert. “With the right policies, they can have both.” 26. How does the writer show the effect of Shanghai’s “cool city” projects? A. By telling a personal story. B. By listing specific data. C. By giving an example of a resident. D. By comparing different cities. 27. What does the underlined phrase “urban heat island effect” mean? A. 城市绿岛效应 B. 城市热岛效应 C. 城市光岛效应 D. 城市雨岛效应 28. Which of the following is TRUE about Shanghai’s “cool city” projects? A. They replaced all asphalt roads with permeable pavement. B. They reduced summer temperatures by 3-5℃ across the city. C. Reflective roofing helps cut down air conditioning use. D. They have planted 1,200 million trees since 2020. 29. What is the structure of the passage? A. ①/②③④⑤ B. ①/②③④/⑤ C. ①②③④/⑤ D. ①②/③④/⑤ 30. What is the best title for the passage? A. Balancing Urban Development and Climate Regulation B. The History of Shanghai’s Green Space Construction C. How to Build More High-Rise Buildings in Cities D. The Disadvantages of Asphalt Roads and Concrete Buildings C The Hulunbuir Grassland in Inner Mongolia is one of China’s largest natural grasslands. For decades, it has maintained a delicate balance: grass feeds deer, deer feed wolves, and wolf droppings fertilize the soil to help grass grow. But in the 1980s, this balance was broken. Local herders killed large numbers of wolves to protect their sheep, as wolves occasionally preyed on livestock. Without wolves, the deer population exploded — from 50,000 to 200,000 in just 10 years. Too many deer ate grass faster than it could grow. By the 2000s, 40% of the grassland had turned into sand, and many deer died of starvation. In 2010, the local government launched a “grassland restoration” project. They reintroduced 200 wolves to the grassland and restricted overgrazing by herders. At first, some herders opposed the plan, fearing more sheep would be killed. But within 5 years, the results were clear: the deer population dropped to a sustainable level, grass grew back, and the sandified land decreased by 60%. Scientists say the Hulunbuir case proves that human intervention (干预) must respect natural balance. “We can’t remove one species and expect the ecosystem to stay healthy,” said Dr. Li, an ecologist. “Every creature plays a role — even predators like wolves.” Today, the grassland is thriving again, and herders earn more money from eco-tourism than they ever did from raising sheep. 31. What was the original ecological balance of Hulunbuir Grassland? A. Grass → deer → wolves → fertile soil → grass. B. Sheep → wolves → grass → sand → sheep. C. Wolves → deer → grass → herders → wolves. D. Grass → sheep → herders → wolves → grass. 32. Why did the deer population drop sharply in the 2000s? A. Because wolves killed too many deer. B. Because herders hunted deer for meat. C. Because overgrazing led to food shortage. D. Because the government moved deer to other areas. 33. What was the key measure of the 2010 grassland restoration project? A. Killing more wolves to protect sheep. B. Reintroducing wolves and restricting overgrazing. C. Planting artificial grass to feed deer. D. Moving all herders away from the grassland. 34. What can we infer from the passage? A. Predators like wolves are harmful to grassland ecosystems. B. Human intervention always destroys natural balance. C. Respecting natural balance leads to sustainable development. D. Eco-tourism is more harmful than raising sheep. 35. What is the main purpose of the passage? A. To encourage people to hunt wolves for livestock protection. B. To introduce the history of sheep raising in Inner Mongolia. C. To explain the importance of maintaining natural ecological balance. D. To compare different grassland restoration methods. D Fifteen-year-old Chen Mo from Hangzhou invented a “water balance device” to help households save tap water. The device, which won the 2025 National Youth Innovation Award, collects rainwater and reuses household greywater (laundry and shower water) for toilet flushing and garden watering. “I got the idea when I saw my grandma using tap water to water her potted plants,” Chen said. “Hangzhou gets over 1,500 millimeters of rain every year, but most of it goes down the drain. I wanted to balance water use and reduce waste.” The device has three parts: a rainwater collector on the roof, a filter to clean greywater, and a storage tank. It costs only 200 yuan to make, using recycled plastic barrels and simple filters. Tests show it can save a family of three up to 40% of their monthly tap water use. Unlike expensive commercial water recycling systems, Chen’s device is affordable for low-income families. Chen faced many challenges during development. Finding a filter that could clean greywater without getting clogged (堵塞) took 6 months of trial and error. He also had to convince his parents that the device wouldn’t leak or smell. Now, 20 families in his community use the device, and the local government plans to promote it across the city. “Innovation doesn’t have to be complicated,” Chen said. “Small ideas from students can make a big difference in balancing resource use and protecting the environment.” 36. What is the main function of Chen Mo’s “water balance device”? A. To purify drinking water for families. B. To collect rainwater and reuse greywater. C. To increase the city’s rainfall. D. To heat water for showers. 37. Why did Chen Mo invent the device? A. Because his grandma asked him to water plants. B. Because he wanted to win an innovation award. C. Because he noticed rainwater was being wasted. D. Because his family couldn’t afford tap water. 38. What is an advantage of Chen’s device compared to commercial systems? A. It is much cheaper to make. B. It can purify drinking water. C. It never gets clogged. D. It uses electricity to filter water. 39. What difficulty did Chen face during development? A. Finding a filter that didn’t clog easily. B. Convincing the government to fund him. C. Collecting enough rainwater in dry seasons. D. Teaching families how to use the device. 40. What is the main idea of the passage? A. Commercial water recycling systems are too expensive. B. A teenager’s simple invention helps balance water use. C. Hangzhou gets too much rain every year. D. Greywater is harmful to the environment. E (七选五) 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项，选项中有两项为多余选项。 As students, we often struggle to balance heavy schoolwork and environmental protection.

Before the campaign, the school canteen wasted over 100 kilograms of food every day — students often took more than they could eat, and leftover rice, vegetables and meat were thrown into trash cans. Under the new campaign, students are encouraged to take half a plate of food first. If they are still hungry, they can go back for more. The canteen also adjusted portion sizes: small portions for younger students and large portions for older students. Student volunteers stand by the trash cans every lunchtime to record food waste and remind students to take only what they need. In just one month, food waste dropped by 70%. The canteen saved over 3,000 yuan on food costs, which was used to buy books for the school library. “The campaign taught me to value food,” said Wang Lin, a Grade 8 student. “I used to take too much and throw away half. Now I only take what I can finish.” The school plans to expand the campaign next semester, adding a “Zero Waste Day” every Friday. Teachers say the campaign not only reduces waste but also teaches students the importance of balancing resource use. 66.

Instead, they can coexist in harmony if we find the right balance. My hometown used to have a polluted river — factories poured waste into it, and fish disappeared. Five years ago, the government closed the illegal factories and built a wetland park along the river. Now the river is clear, and many tourists come to visit, bringing income to local businesses. This proves that protecting the environment can actually boost economic growth. To achieve this balance, we should promote eco-friendly industries and avoid high-pollution projects. Small actions like sorting garbage and saving water also help. Let’s work together for a greener and more prosperous future. 1 学科网（北京）股份有限公司 $
