It is in our water bottles, shopping bags, and food containers. It is even in our clothes. Since the 1950s, humans have produced about 8.3 billion tons of plastic. Most of it — about 79% — has ended up in landfills or the natural environment. Plastic is useful because it is light, strong, and cheap. But it is also a huge problem. Most plastic is not biodegradable, which means it does not break down naturally. A plastic bottle can take up to 450 years to decompose（分解）. Even then, it does not really disappear — it just becomes tiny pieces called microplastics. Microplastics have been found everywhere: in the deepest oceans, on the highest mountains, and even in our food and drinking water. Scientists are still studying the effects of microplastics on human health, but the results so far are worrying. So what can we do? Many countries are banning single-use plastics like straws and bags. Some companies are developing new materials that can break down more easily. But the most important thing is for each of us to change our habits — use fewer plastic products, reuse what we can, and recycle properly. The plastic problem is huge, but it is not too late to solve it. Every small step counts. 26. How much plastic has ended up in landfills or the natural environment? A. About 8.3 billion tons. B. About 79% of all plastic produced. C. About half of all plastic produced. D. About 450 million tons. 27. What does the word "biodegradable" mean in the passage? A. Able to be recycled into new products. B. Able to be broken down naturally. C. Able to be used again. D. Able to be burned safely. 28. How long can a plastic bottle take to decompose? A. About 50 years. B. About 100 years. C. Up to 450 years. D. Up to 1,000 years. 29. What are microplastics? A. Tiny pieces of plastic. B. A new type of plastic. C. Plastic that can decompose. D. Plastic used for food containers. 30. What is the main message of the passage? A. Plastic is too useful to give up. B. We should stop using all plastic products immediately. C. Everyone can help solve the plastic problem by changing habits. D. The plastic problem is impossible to solve. B How One Person Can Make a Difference When we hear about environmental problems, it is easy to feel powerless. We might think, "I'm just one person. What can I do?" But the truth is that every person can make a difference. Here are some simple actions that can help protect our planet. First, reduce your waste. Think before you buy. Do you really need that new item? Can you borrow it instead? When you shop, bring your own bags and avoid products with too much packaging. Second, reuse what you have. Before throwing something away, ask yourself if it can be used again. Glass jars can become storage containers. Old clothes can be turned into cleaning rags. Even broken furniture can be repaired or repurposed. Third, recycle properly. Learn what can be recycled in your area and separate your waste correctly. Rinse（冲洗）containers before putting them in the recycling bin. A small mistake can ruin a whole batch of recyclables. Fourth, spread the word. Talk to your family and friends about environmental protection. Share what you have learned on social media. When more people join the effort, the impact becomes much bigger. One person's actions may seem small, but imagine if everyone did the same. Together, we can create a cleaner, healthier world. 31. What is the first action suggested to help protect the planet? A. Reuse what you have. B. Reduce your waste. C. Recycle properly. D. Spread the word. 32. What should you do with glass jars according to the passage? A. Throw them away. B. Recycle them only. C. Turn them into storage containers. D. Sell them. 33. Why is it important to rinse containers before recycling? A. To make them look clean. B. To prevent ruining a whole batch of recyclables. C. To save space in the bin. D. To make them heavier. 34. What does "spread the word" mean in the passage? A. Write a book about the environment. B. Tell others about environmental protection. C. Start a recycling company. D. Give speeches every day. 35. What is the writer's attitude toward environmental protection? A. Pessimistic — it is already too late. B. Hopeful — small actions can make a big difference. C. Doubtful — one person cannot change anything. D. Indifferent — it is not our problem. 第四部分 七选五（共10分，每小题2分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Ways to Live a Greener Life Living a greener life doesn't mean you have to make big changes overnight. 36. _______ Here are some easy ways to start.

The goal of zero waste is to send nothing to landfills. People who follow this lifestyle try to produce as little waste as possible. The movement was started by Bea Johnson, a woman from California. In 2008, she decided to reduce her family's waste. She started by refusing single-use plastics and buying products with no packaging. Her family now produces only a small jar of waste per year. How do they do it? They follow five rules: refuse, reduce, reuse, recycle, and rot（腐烂）. They refuse things they don't need, like free plastic bags. They reduce what they buy. They reuse items as much as possible. They recycle whatever they can. Finally, they compost（堆肥）food waste, letting it rot and become soil. The zero waste lifestyle is not easy. It requires planning and effort. But Johnson says it has many benefits. Her family saves money, eats healthier food, and lives a simpler life. Today, the zero waste movement has spread to many countries. More and more people are trying to reduce their waste. They are learning that a different way of life is possible. 51. What is the goal of the zero waste movement? 52. Who started the zero waste movement and when? 53. How much waste does Bea Johnson's family produce each year now? 54.
