Air pollution, water pollution, and waste are becoming more and more serious. But the good news is — every one of us can 11 a part in making the world greener. We can start with small things. For example, we should turn off lights when we leave a room. This helps us 12 electricity. We can also reuse plastic bags or use cloth bags when shopping. This reduces the number of plastic bags that 13 each day. Many schools are now teaching students to 14 waste into different groups — paper, plastic, glass, and metal. Then, these materials can be 15 and turned into new products. Recycling is very important, because if we don’t do it, more rubbish 16 in landfills. Trees are also very important. They give us oxygen and help clean the air. But many people still 17 trees to build houses or make paper. This is very 18 to the environment. We must stop this and plant more trees every year. In the future, more 19 will be used in cities. For example, buses and cars may run on solar or electric power. This means less pollution and cleaner air. Also, new laws 20 soon to help protect the environment. Students can also help by joining school clubs. Many schools have “Green Teams” that organize clean-up days or planting activities. If you join one, you’ll find that caring for the Earth is not only useful — it’s also 21 ! Some people say, “One person can’t change the world.” But that’s not true. If every student in our school starts recycling, and every family turns off unused lights, big changes 22 . Remember: every small action matters. You can 23 your friends and family to join you. Don’t wait — start today! We only have one Earth. If we all 24 about it and act now, we can make sure it stays beautiful and healthy for the next generation. The future 25 us — and it starts with you. 11. A. take   B. play   C. make   D. get 12. A. save   B. waste   C. use   D. lose 13. A. produce   B. are produced   C. producing   D. will produce 14.

Every Wednesday afternoon, instead of going straight home, members of the club stay behind to patrol the campus. Armed with gloves and trash bags, they carefully pick up used batteries, empty plastic bottles, and piles of waste paper scattered around the playground and corridors. After sorting these wastes into different categories, they send them to the local recycling center every Friday morning. Last month, the club launched a creative campaign called "No Car Day". They designed posters and gave speeches during the morning assembly, persuading parents and teachers to leave their cars at home. The response was amazing. On that day, the streets around the school were filled with students riding bikes or walking to school. The club even measured the air quality and found that the PM2.5 level dropped significantly. The air felt fresher, and the streets were much quieter. Now, the club plans to make this activity a monthly tradition. 26. What do members of the Green Club do every Wednesday afternoon? A. They play sports on the playground. B. They collect and sort waste on campus. C. They attend extra classes for science. D. They deliver speeches in the hall. 27. How often do they send the sorted waste to the recycling center? A. Once a week. B. Twice a week. C. Once a month. D. Every other day. 28. Which of the following is NOT a result of "No Car Day"? A. The air quality improved. B. The streets became quieter. C. More parents drove their cars. D. Students rode bikes to school. B Imagine waking up in the year 2050. Thanks to breakthroughs in green technology, our cities have transformed dramatically. First, the roads are no longer dominated by noisy, gasoline-powered cars. Instead, most vehicles run on electricity or solar power, gliding silently through the streets. This shift has not only reduced air pollution but also lowered the noise levels, making the city a more peaceful place to live. Second, the gray concrete buildings we see today are covered with lush rooftop gardens. These vertical gardens act as the "lungs" of the city, absorbing carbon dioxide and releasing fresh oxygen. Moreover, smart robots will handle waste management. Equipped with sensors, these robots can automatically identify and separate recyclable materials from household waste with high accuracy. However, scientists warn that technology alone isn't a silver bullet. If we continue to waste resources without thinking, even the smartest robots won't be able to save us. Ultimately, the health of our planet depends on whether we choose to live a simpler, low-carbon lifestyle. 29. What powers most vehicles in the future city described in the text? A. Coal and nuclear energy. B. Electricity and solar power. C. Gasoline and diesel. D. Wind and water. 30. Why are rooftop gardens compared to the "lungs" of the city? A. Because they store fresh water. B. Because they provide shade for people. C. Because they produce vegetables for the market. D. Because they absorb CO₂ and release O₂. 31. What is the main message the writer wants to convey in the second passage? A. Robots will solve all environmental problems. B. Future cities will have no cars at all. C. Technology is useless without a change in lifestyle. D. Living in 2050 will be very expensive. C Every year, millions of tons of plastic waste flow into the oceans. Most of this waste comes from single-use items like straws, bottles, and shopping bags. These plastics do not break down easily. Instead, they break up into smaller pieces called microplastics, which are often eaten by fish and birds. Scientists have found microplastics even in the deepest parts of the sea and in the food we eat. To fight against this, many countries are taking action. For example, some supermarkets have stopped providing free plastic bags. Others encourage customers to bring their own reusable containers. However, experts point out that the best solution is not just cleaning up the ocean, but stopping the use of plastic in the first place. Reducing consumption is the first step toward a cleaner planet. 32. Where does most plastic waste in the ocean come from? A. Natural disasters like storms. B. Single-use daily products. C. Waste from fishing boats. D. Industrial factories. 33. What happens to plastics in the ocean over time? A. They break down into microplastics. B. They sink to the bottom immediately. C. They turn into harmless gas. D. They become food for large fish. 34. What does the underlined word "consumption" in the last paragraph probably mean? A. Saving. B. Throwing. C. Buying and using. D. Producing. 35. What is the main idea of the passage? A. Microplastics are good for fish. B. Cleaning the ocean is impossible. C. Stopping plastic use is the best way to protect the ocean. D. Supermarkets should sell more plastic products. D In recent years, "fast fashion" has become popular around the world. Clothing brands release new styles every week, and clothes are sold at very low prices. As a result, people tend to buy more clothes than they need. Once these cheap clothes go out of style or break, they are often thrown into the trash. In fact, the fashion industry is now one of the largest polluters in the world, second only to the oil industry. To solve this problem, some creative designers are turning waste into treasure. They collect old clothes and even plastic bottles, then process them into new fabric. This kind of "circular fashion" not only reduces waste but also saves water and energy needed to grow cotton. Furthermore, some apps now allow users to exchange clothes online. By choosing second-hand clothing, we can extend the life of garments and reduce our environmental footprint. 36. Why do people buy too many clothes according to Paragraph 1? A. Because clothes are very cheap. B. Because they have no other hobbies. C. Because old clothes wear out quickly. D. Because they want to help the poor. 37. How does the writer describe the pollution caused by the fashion industry? A. It causes the least pollution. B. It is the biggest polluter. C. It is the second-largest polluter. D. It causes no pollution at all. 38. What is "circular fashion" mentioned in the text? A. Making clothes from waste materials. B. Selling clothes in circles. C. Wearing clothes in circles. D. Donating clothes to charity. 39. Which of the following is NOT mentioned as a way to reduce fashion pollution? A. Turning plastic bottles into fabric. B. Exchanging clothes through apps. C. Choosing second-hand clothing. D. Buying more newly released clothes. 40. What is the purpose of this passage? A. To teach people how to design clothes. B. To encourage people to buy more fast fashion. C. To show the harm of fast fashion and suggest solutions. D. To compare oil and cotton industries. （二）阅读下面短文，从所给选项中选出能填入空白处的最佳选项，使短文通顺，结构完整，其中有一项是多余选项。 When we talk about saving the planet, we usually think about recycling or driving less. However, what we eat also has a huge impact on the environment. 41 Here are some simple changes you can make to your diet to help protect the Earth. First, try to reduce food waste. About one-third of all food produced globally is wasted. When food rots in landfills, it produces methane, a greenhouse gas much stronger than carbon dioxide. 42 Plan your meals before shopping and try to use leftovers creatively. Second, consider eating more plant-based meals. Producing meat, especially beef, requires a lot of land, water, and feed. 43 Even if you don't become a vegetarian, just having one meat-free day a week can make a big difference. Third, choose local and seasonal food. Food that travels long distances by plane or truck uses lots of fossil fuels. 44 It is usually fresher, tastier, and better for the environment. Finally, avoid ultra-processed foods. These foods often come in layers of plastic packaging, which adds to pollution. 45 Cooking at home with fresh ingredients is healthier for you and creates less waste. By making smarter choices about what we put on our plates, we can truly play a part in creating a green world.A. Buying local food supports nearby farmers and reduces transport pollution. B. Many people think global warming is not a real problem. C. So, buying only what you need is a powerful way to fight climate change. D. It also takes a lot of energy to process and package these snacks. E. Growing plants generally uses fewer natural resources than raising animals. F. We should never wash fruits before eating them. 四、词汇运用 （一）阅读下列短文，从方框中选出适当的词或短语并用其适当形式填空，使短文通顺，意思完整，每词或短语限用一次。（共10小题;每小题1.5分, 计15分） floor water traveler short think of The Amazon is the world’s second longest river.

The Amazon is part of a large area called the Amazon Rain Forest that has a lot of plants and animals. In some places, the plants are so thick that sunlight can’t reach the rainforest 48 . The famous explorer Francisco de Orellana gave the river its name. At that time, he and his team met a group of wild women. They made him 49 an old story about the brave Amazons.

I’m a little fish from an ocean in the south of the earth. Our home was clean and beautiful many years ago. The water was clear like b 56 glass, and colourful flowers grew around the coast. B 57 now, everything is different. Our ocean is in a mess. Plastic bags, bottles and other rubbish cover the s58 of it. The once clean water is now very dirty and smells bad, making it hard for us to live. Some old fish give suggestions to us—we can try our best to p 59 our home or just move away. We try hard to clean the ocean. We collect waste between rocks and carry it away, but it is too h 60 and more rubbish keeps coming. Many families decide to move to the north.

Before you throw them away, think about "upcycling"! Unlike traditional recycling, which breaks materials down into raw parts, upcycling creatively transforms old items into new products of higher quality or value. For instance, an artist in Nanjing collects discarded wooden pallets and broken skateboards. He sands them down and paints them bright colors to create stylish chairs and bookshelves. This process saves trees and greatly reduces the amount of waste sent to landfills. Many schools are joining this trend, too. Students collect used plastic bottles and turn them into cool pencil cases or art works. This not only saves natural resources but also sparks creativity. Upcycling proves that one person's trash can truly be another person's treasure. Let's start small and make a big difference together. 回答下面五个问题，每题答案不超过5个词。 66.What shouldn't we do with old jeans? 67.What does upcycling turn old things into? 68.Where is the artist mentioned in the text? 69.What do students use to make pencil cases? 70.Whose treasure can old things be? 六、书面表达(共1小题，计20分) 假设你是阳光中学八年级的学生李华。你们学校正在开展“绿色校园”（Green School）项目，校英语报为此征文。请你写一篇短文投稿，介绍你们已经采取的措施，以及未来还计划做些什么来让校园更环保。 内容包括： 现状与行动：你们已经做了什么？（至少两点，如垃圾分类、节约用水等） 未来计划：下个月还将推行什么新措施？（如太阳能板将被安装、旧书将被回收等） 呼吁：号召大家加入行动。 要求： 词数 90 左右（开头已给出，不计入总词数）； 要点齐全，可适当发挥； 文中不得出现真实的人名或校名。 Dear Editor, I am Li Hua from Class 2, Grade 8.

To build a green school, we have taken many actions so far. First, waste is sorted into different groups every day, such as recyclables and kitchen waste. Also, lights are turned off immediately when we leave the classroom to save electricity. To make our school even greener, more measures will be carried out next month. Solar panels will be installed on the roofs to use clean energy. Old textbooks will be collected and shared among students to save paper. More trees will be planted along the school paths, too. Small actions lead to big changes. Let’s work together for a greener world! Yours, Li Hua 2 学科网（北京）股份有限公司 $
