(5分) Lucy: Have you seen the news about plastic pollution in the ocean? It said that by 2050, there will be more plastic than fish in the sea. That is terrifying. Tom: I saw that too. It is a huge problem. But I also read about some teenagers who are making a difference. One girl built a robot that can detect plastic in the ocean. Lucy: Really? That is amazing! How did she do it? Tom: She used a remotely-operated vehicle, or ROV, and added sensors to it. The ROV can find plastic waste underwater and send information back to the computer. She won a science award for her invention. Lucy: That gives me hope. It shows that young people can make a real difference. Maybe we should start a recycling programme at our school. Tom: Great idea! If everyone does their part, the situation will improve. Small actions add up to big changes. 21. What prediction does the news make about plastic in the ocean? A. Plastic will disappear by 2050. B. There will be more plastic than fish by 2050. C. Fish will learn to eat plastic. D. The ocean will be completely clean. 22. What did the teenage girl build to help solve the plastic problem? A. A plastic-eating machine. B. A robot that can detect plastic in the ocean. C. A new type of fishing net. D. A solar-powered boat. 23. How does the ROV detect plastic? A. It uses cameras. B. It uses sensors to find plastic underwater. C. It collects all the plastic. D. It makes plastic harmless. 24. What does Lucy suggest they do at school? A. Start a recycling programme. B. Build their own robot. C. Write to the government. D. Stop using plastic completely. 25. What is the main message of the conversation? A. Only scientists can help. B. The situation is hopeless. C. Small actions add up to big changes. D. Plastic is not a problem. B. Read and choose the best answer. (5分) 1.Pollution is one of the biggest challenges facing our planet today. From the air we breathe to the water we drink, no part of the natural world has been left untouched. The good news is that more and more people are becoming aware of the problem and taking action. 2.Air pollution is caused mainly by factories, cars, and power plants that burn fossil fuels. Tiny particles called PM2.5 can enter our lungs and cause serious health problems. In many cities, people are advised to wear masks on heavily polluted days. Governments are working on solutions, but change will not happen overnight. 3.Plastic pollution is another major concern. About eight million tons of plastic waste enter the ocean every year. This plastic does not decompose. Instead, it breaks down into tiny pieces that are eaten by marine animals. Scientists are developing new ways to clean up the plastic, but prevention is still the best solution. 4.However, there are reasons to be hopeful. Young people around the world are taking the lead in environmental activism. They are organising clean-ups, starting recycling programmes, and inventing new technologies to fight pollution. Their actions show that age is not a barrier to making a difference. 5.In conclusion, the fight against pollution will not be won overnight. But with continued effort and innovation, a cleaner, healthier planet is possible. As the saying goes, we do not inherit the Earth from our ancestors; we borrow it from our children. 26. What is the passage mainly about? A. How to wear masks correctly. B. The challenges of pollution and reasons for hope. C. The benefits of plastic. D. How factories operate. 27. What causes air pollution according to Paragraph 2? A. Natural disasters. B. Factories, cars, and power plants burning fossil fuels. C. Volcanic eruptions. D. Too many trees. 28. Why is plastic pollution particularly dangerous? A. It makes the ocean look dirty. B. It does not decompose and breaks into tiny pieces eaten by animals. C. It is too expensive to clean up. D. It only affects beaches. 29. What does the writer say about young people's actions? A. They are too young to help. B. They are leading the fight against pollution. C. They only care about school. D. They are waiting for adults to act. 30. What is the writer's message in the last paragraph? A. The situation is hopeless. B. The Earth can be saved with continued effort. C. We should give up trying. D. Pollution is not a serious issue. C. Choose the best answer and complete the passage. (12分) Every year, about eight million tons of plastic waste enters our oceans. This is equivalent to dumping a garbage truck full of plastic into the sea every minute. If this continues, the amount of plastic in the ocean _______(31) more than the weight of all fish by 2050. The problem with plastic is that it does not break down naturally. Instead, it slowly _______(32) into tiny pieces called microplastics. These tiny particles are eaten by fish and other marine animals. When we eat seafood, these microplastics enter our bodies too. Scientists are still studying the long-term health effects, but the news is not good. However, solutions _______(33). Many countries _______(34) to ban single-use plastics like straws and bags. New technologies _______(35) to clean up the plastic already in the ocean. If we act now, the situation _______(36) before it is too late. The key is to start today, not tomorrow. ( )31.

Answer the questions. (12分) Sophie was 15 years old when she learned about the plastic problem in the ocean. She wanted to help, but she did not know how. Then she had an idea. She would build a remotely-operated vehicle, or ROV, that could detect plastic underwater. Sophie spent months working on her invention. She used a small underwater drone and added special sensors that can identify different types of plastic. The ROV sends real-time data back to a computer, showing where the plastic is located. This makes it much easier for clean-up teams to find and remove plastic waste. Her project won first prize at a national science fair. But more importantly, it caught the attention of several environmental organisations. They offered to help Sophie improve her design and test it in real ocean conditions. Sophie's story shows that you do not need to be a scientist or an adult to make a difference. All you need is a problem you care about and the determination to find a solution. She is now working with a team of engineers and hopes that her ROV will one day be used to clean up plastic pollution around the world. Task 1: Answer the questions. 37.
