Reading comprehension（阅读理解选择题）（12分） Read the passage and choose the best answer for each question. The world's oceans are facing a plastic pollution crisis. According to a recent study, more than 8 million tons of plastic enter the ocean every year. This is equivalent to dumping one garbage truck of plastic into the ocean every minute. By 2050, it is estimated that there will be more plastic in the ocean than fish by weight. Plastic does not biodegrade like organic materials. Instead, it breaks down into smaller particles called microplastics, which are less than 5 millimetres in size. These microplastics are easily ingested by marine animals, including fish, sea turtles, and whales. When we eat seafood, we are also consuming these tiny plastic particles. Studies have found microplastics in human blood and organs. In response to this crisis, scientists and engineers are developing innovative solutions. One promising technology is the Ocean Cleanup System, designed by a Dutch inventor. This system uses a large floating barrier that captures plastic waste while allowing marine life to swim safely underneath. The collected plastic is then taken to land for recycling. Another solution is the development of biodegradable plastics made from plant-based materials. These plastics can break down naturally in the environment without leaving harmful residues. However, these alternatives are still more expensive to produce than traditional plastics. The fight against plastic pollution requires action from everyone — governments, companies, and individuals. Many countries have already banned single-use plastics. Businesses are investing in sustainable packaging. And individuals are making environmentally conscious choices every day. While the problem is enormous, collective action can lead to real change. 1. How much plastic enters the ocean every year according to the study? A. More than 8 million kilograms. B. More than 8 million tons. C. More than 80 million tons. D. More than 8 billion tons. 2. What are microplastics? A. Large pieces of plastic waste. B. Plastic particles smaller than 5 millimetres. C. Biodegradable plastic materials. D. Plastic that has been recycled. 3. Why are microplastics dangerous to humans? A. They are very sharp and can cut our skin. B. They release harmful chemicals into the air. C. They enter our bodies when we eat seafood. D. They cause global warming. 4. What is the Ocean Cleanup System designed to do? A. To produce more biodegradable plastic. B. To capture plastic waste in the ocean. C. To ban single-use plastics globally. D. To create new types of plastic. 5. Why are biodegradable plastics not widely used yet? A. They are harmful to marine life. B. They break down too quickly. C. They are more expensive to produce. D. They are not effective. 6. What is the main message of the passage? A. Plastic pollution is a serious problem, but there are solutions. B. Plastic pollution is not a serious problem. C. We should stop eating seafood. D. Only governments can solve the plastic problem. C. Cloze test（完形填空）（12分） Read the passage and choose the best answer for each blank. E-waste, or electronic waste, is one of the fastest-growing types of pollution in the world. Every year, we produce over 50 million tons of e-waste — that's the ____(1)____ of about 4,500 Eiffel Towers. This waste includes old phones, computers, TVs, and other electronic devices. These devices ____(2)____ valuable materials like gold, silver, and copper. However, they also contain harmful substances such as lead and mercury. When e-waste is not properly ____(3)____, these toxic materials can leak into the soil and water. This ____(4)____ serious health problems for people living near dumping sites. The good news is that up to 80% of e-waste can be ____(5)____. The materials inside old electronics can be recovered and used to make new products. However, less than 20% of e-waste is currently recycled. This is a huge missed opportunity. To ____(6)____ this problem, governments around the world are creating new laws. Many countries now require electronics manufacturers to take back and recycle old products. As consumers, we can also help by repairing our devices instead of replacing them. 1.

Answer the questions（回答问题）（12分） Read the passage and answer the questions below. Renewable energy is energy that comes from natural sources that are constantly replenished. The five main types are solar, wind, hydroelectric, geothermal, and biomass energy. Unlike fossil fuels, which are finite and release harmful greenhouse gases when burned, renewable energy sources produce little to no pollution. In China, the transition to renewable energy has been remarkable. In 2022, China installed more solar panels than the rest of the world combined. The country is also the world's largest producer of wind energy. In addition, China is investing heavily in hydroelectric power, with the Three Gorges Dam being the world's largest power station. However, renewable energy also has challenges. Solar and wind power are weather-dependent, meaning they produce electricity only when the sun shines or the wind blows. This makes it difficult to ensure a constant supply. To solve this problem, experts are working on energy storage technologies. Batteries are becoming more efficient and affordable. Another solution is the development of smart grids, which can balance energy supply and demand in real time. These systems use advanced software to manage electricity flow. In some regions, homes can even sell excess solar energy back to the grid. The future of energy is likely to be a mix of different renewable sources. By diversifying our energy supply and improving storage technology, we can create a clean, sustainable, and reliable energy system for generations to come. Task 1: Answer the following questions. 1. Are there five or six main types of renewable energy mentioned in the passage? _________________________________________________________________ 2. What is the Three Gorges Dam known for? _________________________________________________________________ 3. When did China install more solar panels than the rest of the world combined? _________________________________________________________________ 4. Where do solar and wind power face challenges? _________________________________________________________________ 5. Why are energy storage technologies important for renewable energy? _________________________________________________________________ Task 2: Personal response.（请写出自己的看法，约30词） 6. Do you think renewable energy can completely replace fossil fuels in the future? Why or why not? Please write down your own understanding. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Part 4 Writing（第四部分 写作）（共18分） VII.

VIII. 写作 Dear Alex, How's everything going? I'd like to share with you my growing concern about plastic pollution. Every day, I see people using plastic bags, bottles, and straws without thinking about the consequences. It breaks my heart to know that millions of marine animals die each year because of plastic waste. I've decided to take action by refusing single-use plastics and bringing my own reusable bags and bottles. I believe it is important for teenagers like us to take action because we are the ones who will inherit this planet. Even small actions add up to make a difference. We don't need to solve the whole problem overnight — we just need to start somewhere. I also started an environmental club at school and we are planning a beach clean-up next month. What are you doing to help the environment? I'd love to hear your ideas! Yours, Li Ming 学科网（北京）股份有限公司 $
