Nowadays, human activity produces huge amounts of waste, which has 16. ______ serious pollution to land, water and air. Luckily, everyone can make a difference with small daily changes. First, reduce means cutting down unnecessary waste. Many people buy more goods than they actually 17. Too much packaging, single‑use cups and plastic lunch boxes are the main waste in daily life. If we choose simple packaging and refuse disposable goods, we can greatly 18. our waste output. Second, reuse means using items again instead of throwing them away. Many daily things are still useful after being used once. Empty jars can hold small things. Old clothes can be donated or reused as cleaning tools. Reusing items can greatly 19. the need for new products. Third, recycle is a key way to turn waste into treasure. Paper, metal, glass and plastic can be processed and 20. into new materials.

Single‑use plastic products are the most difficult waste to deal with. They cannot break down easily and will stay in nature for hundreds of years. They pollute soil, rivers and oceans, and even harm wild animals. Reducing disposable waste is the easiest way to practice the 3R rules in daily life. Schools and families can take simple measures. Students can bring their own water cups and lunch boxes instead of using disposable ones. Shoppers can prepare reusable cloth bags and refuse free plastic bags. Many cities have started strict rules to limit disposable plastic products. More green and reusable products are designed to take their place. It proves that reducing waste does not mean lowering our life quality, but means living a healthier and greener life. 26. What is the biggest problem of disposable plastic products? A. They cost too much money. B. They are hard to break down in nature. C. They cannot be used for a long time. D. They make people’s life inconvenient. 27. What does the writer advise students to do? A. Use more disposable lunch boxes. B. Bring reusable cups and boxes. C. Stop shopping in supermarkets. D. Throw plastic waste everywhere. 28. What can we learn from the passage? A. Reducing waste improves our life quality. B. Plastic waste can disappear in several days. C. Only cities need to protect the environment. D. Disposable products should be all forbidden. B Waste sorting is the first step of recycling. In general, daily waste is divided into four kinds: recyclable waste, kitchen waste, harmful waste and other waste. Each kind of waste has its own recycling value and processing method. Recyclable waste includes paper, metal, glass and clean plastic. These wastes can be reprocessed into new products and save raw materials. Kitchen waste is also called wet waste. It can be turned into organic fertilizer to help plants grow. Harmful waste includes used batteries, old medicines and broken fluorescent lamps. They contain poisonous materials. If mixed with common waste, they will pollute soil and underground water seriously. Other waste refers to the waste that cannot be reused or recycled. Many teenagers think waste sorting is troublesome. But in fact, after forming a habit, it will become a natural daily action. Correct waste sorting can reduce recycling costs, save resources and protect our living environment. It is a necessary green skill for modern students. 29. Which waste can be made into fertilizer? A. Metal waste B. Kitchen waste C. Harmful waste D. Paper waste 30. Why must we separate harmful waste from other waste? A. Because it can be recycled easily. B. Because it is too clean to throw away. C. Because it contains poisonous materials. D. Because it can be used as plant food. 31. What is the advantage of waste sorting? A. It makes people’s life busy. B. It increases production costs. C. It helps save resources and protect environment. D. It helps produce more disposable products. 32. What is the best title for the passage? A. The Importance of Waste Sorting B. How to Produce New Products C. The History of Environmental Protection D. Different Kinds of Daily Food C Reusing old items is a low‑cost and eco-friendly way to follow the 3R rules. Different from recycling, reusing does not need industrial processing, so it saves more energy and produces no new pollution. Old containers such as bottles and boxes can be reused for storage. Old clothes can be donated to poor areas or reused as household cleaning cloths. Even broken furniture can be repaired and reused again. Reusing items lengthens their service life and delays waste production. Now “upcycling” is becoming popular among young people. It means turning useless old waste into creative and beautiful handicrafts. For example, wasted glass bottles can be turned into vases, and old cartons can be made into bookcases. Reusing and upcycling teach teenagers to value resources. It helps us realize that most waste is not useless. With creativity and good habits, we can turn waste into wealth and live a low-carbon life. 33. What is the advantage of reusing compared with recycling? A. It needs more factory work. B. It saves energy and has no new pollution. C. It produces more new waste. D. It costs more money and time. 34. What does “upcycling” mean? A. Throwing away all old things. B. Buying more new green products. C. Turning waste into creative handicrafts. D. Sorting waste into four different kinds. 35. Which of the following is reusing behavior? A. Throw old boxes into rubbish bins. B. Repair old chairs and use them again. C. Buy new bottles to replace old ones. D. Burn old paper for heating. 36. What is the writer’s attitude towards reusing? A. Doubtful B. Strict C. Supportive D. Worried D Natural resources are the treasure of the earth. However, many resources are non‑renewable, which means they cannot be produced again in a short time. Oil, coal and minerals all belong to non‑renewable resources. Over‑waste will lead to resource shortage in the future. The 3R rules are effective ways to protect natural resources. Reduce helps cut down resource consumption. Reuse lowers the demand for new resources. Recycling turns waste into reusable materials and reduces resource exploitation. Protecting natural resources is not only for the present, but also for future generations. Teenagers are the future masters of the earth. We should start with small things: save every drop of water, avoid wasting electricity, reuse daily items and sort waste strictly. Small green habits will finally change the whole world. Protecting resources is protecting our home. 37. What does the underlined word “non‑renewable” mean? A. 可再生的 B. 不可再生的 C. 可循环的 D. 可利用的 38. Which is NOT a 3R function according to the passage? A. Reducing resource consumption. B. Lowering demand for new resources. C. Increasing disposable product use. D. Turning waste into new materials. 39. What can we infer from the passage? A. Natural resources will never run out. B. Teenagers should take action to save resources. C. 3R rules only work for big factories. D. Wasting resources has no bad influence. 40. What is the main idea of the last paragraph? A. We should develop green habits to protect our home. B. It is useless to protect natural resources. C. Modern life needs more resource consumption. D. Resource shortage is not a serious problem. Ⅳ. 词汇运用（每空1分，共10分） A. 根据句意及汉语提示写单词 41. We should form the ______（习惯）of sorting rubbish in daily life. 42.
