Every year, about 8 million tons of plastic waste enter the ocean. This harms sea animals and damages the ecosystem. Many fish and birds eat plastic pieces by mistake and die. Some animals get trapped in plastic waste and cannot move. Scientists have found plastic in the deepest parts of the ocean and on the highest mountains. This shows that plastic pollution is everywhere. It takes about 500 years for a plastic bottle to break down. That means the first plastic bottles ever made are still on the earth today. Many countries are now taking action to reduce plastic pollution. Some places have banned single-use plastic bags and straws. People are encouraged to use reusable bags and bottles. By making small changes in our daily lives, we can all help solve this problem. (　) 21. How much plastic waste enters the ocean every year? A. About 8,000 tons.　　B. About 80,000 tons. C. About 8 million tons.　　D. About 80 million tons. (　) 22. How long does it take for a plastic bottle to break down? A. About 50 years.　　B. About 100 years. C. About 500 years.　　D. About 1,000 years. (　) 23. What action have some countries taken to reduce plastic pollution? A. They have banned all plastic products. B. They have banned single-use plastic bags and straws. C. They have stopped using plastic forever. D. They have made plastic free for everyone. B ★★中等题（第24-27题） The three R's — Reduce, Reuse, Recycle — are a simple but powerful way to help protect our environment. First, we should reduce the amount of waste we produce. This means buying only what we truly need and avoiding products with too much packaging. For example, we can choose to buy fruits and vegetables without plastic wrapping. We can also use digital files instead of printing papers. Second, we should reuse items whenever possible. Instead of throwing away glass jars, we can use them to store food or small objects. Old clothes can be made into cleaning cloths. Reusing items saves resources and reduces the amount of waste that goes into landfills. Third, we should recycle things that cannot be reused. Recycling turns old materials into new products. For example, used paper can be made into new paper. Plastic bottles can be turned into new plastic items. Many cities have recycling programs where people can separate their waste into different bins. By following the three R's, each of us can make a positive difference to the environment. Even small efforts, when multiplied by millions of people, can create great changes. (　) 24. What does "Reduce" mean according to the passage? A. Using more products with packaging. B. Buying only what we truly need. C. Throwing away everything we use. D. Printing more papers. (　) 25. What can old clothes be reused as? A. Plastic bags.　　B. Glass jars. C. Cleaning cloths.　　D. Paper files. (　) 26. What happens to recycled materials? A. They are thrown away. B. They are turned into new products. C. They are stored in landfills. D. They are burned. (　) 27. What does the passage mainly tell us? A. Recycling is the only way to protect the environment. B. The three R's can help us protect the environment. C. We should not use any plastic products. D. Environmental problems are too big to solve. C ★★★拔高题（第28-30题） Air pollution is one of the most serious environmental problems in the world. It is caused by many human activities, including burning fossil fuels, driving cars, and running factories. The effects of air pollution are harmful to both human health and the natural environment. Studies show that air pollution can cause respiratory diseases, heart problems, and even cancer. Children and elderly people are especially at risk. In many cities, people have to wear masks to protect themselves from harmful particles in the air. In addition, air pollution damages crops and forests. It also contributes to climate change by increasing greenhouse gases in the atmosphere. There are several solutions to air pollution. First, we can use clean energy sources like solar, wind, and hydro power. These sources do not produce harmful emissions. Second, we can improve public transportation so that fewer people use private cars. Third, factories should use better technology to reduce their emissions. Many countries have already set strict laws to limit pollution from vehicles and factories. However, solving air pollution requires not only government action but also individual efforts. Each person can help by walking, cycling, or taking public transport. We can also save electricity, which reduces the amount of fossil fuels burned. Small actions, when repeated by many people, can make a big difference. (　) 28. What are some health problems caused by air pollution? A. Skin diseases and headaches. B. Respiratory diseases and heart problems. C. Stomach problems and fever. D. Eye problems and allergies. (　) 29. What clean energy sources are mentioned in the passage? A. Coal and oil.　　B. Natural gas and wood. C. Solar, wind, and hydro power.　　D. Nuclear and chemical power. (　) 30. What is the author's opinion about solving air pollution? A. Only the government should take action. B. It requires both government action and individual efforts. C. There are no effective solutions to air pollution. D. Only factories need to reduce emissions. 第四部分 词汇运用（共10小题，每小题1分，满分10分） ★基础题（第31-35题） 根据句意和汉语提示写出单词的正确形式。 31. We should reduce the use of __________ (塑料) bags. 32.

In many cities, garbage is taken to landfills. A landfill is a large area where waste is buried underground. However, landfills take up a lot of land and can pollute the soil and water nearby. Some cities use incinerators to burn garbage. Burning reduces the volume of waste, but it also produces harmful gases that pollute the air. In recent years, scientists have been looking for better ways to deal with waste. One good solution is waste-to-energy technology. This method turns garbage into electricity or heat. Another solution is composting. Food waste and other organic materials can be broken down into soil fertilizer through composting. This helps plants grow and reduces the need for chemical fertilizers. The best way to reduce garbage is to produce less of it. By choosing reusable products and avoiding unnecessary packaging, we can greatly reduce the amount of waste that ends up in landfills. 46. What is a landfill? 47. What is one problem with incinerators? 48. What can be done with food waste? ★★★拔高题（第49-50题） 49. What is waste-to-energy technology? （请用完整句子作答） 50.

We should protect it because pollution is harming our planet and our health. At home, we can turn off lights to save electricity. We can also separate waste into different bins for recycling. At school, we should not waste paper and we can use both sides of each sheet. I plan to start bringing a reusable water bottle instead of buying plastic bottles. Small actions can make a big difference if everyone joins in. Let's do our part to protect the environment! 任务二参考范文 Why should we reduce, reuse, and recycle? There are several reasons. First, reducing waste helps save natural resources. Second, reusing items reduces the amount of garbage that goes into landfills. Third, recycling turns old materials into new products and saves energy. For example, we can reuse glass jars to store food instead of throwing them away. This simple action reduces waste and saves resources. I hope more people will follow the three R's in their daily lives. To make our planet a better place, everyone needs to take action. If we all work together, we can create a cleaner and healthier world for future generations. 学科网（北京）股份有限公司 $
