However, a new trend is changing the way we see buildings. Architects and city planners are now designing "green roofs"—transforming the tops of office blocks and schools into beautiful gardens filled with grass, colorful flowers, and even small vegetable farms. These rooftop gardens are much more than just pretty scenery; they are a powerful tool for fighting environmental problems. Scientists say that green roofs act like giant sponges. They can absorb up to 70% of rainwater, which prevents the city's drainage system from overflowing and stops the streets from flooding during heavy storms. Moreover, the plants work hard to filter the air. They take in harmful carbon dioxide and release fresh oxygen, making the air cleaner for everyone to breathe. The benefits are also felt inside the building. The layer of soil and plants acts as a natural insulator. In summer, it keeps the heat out, and in winter, it keeps the warmth in. This means people use less electricity for air conditioning and heating, saving both energy and money. Many schools have joined this movement. Students are excited to get their hands dirty, learning how to grow organic food and studying the insects and birds that are attracted to these sky-high habitats. 1. What is the main purpose of Paragraph 1? A. To describe the color of buildings. B. To introduce the new idea of green roofs. C. To complain about the cost of space. D. To explain how to build a farm. 2. What does the underlined word "filter" in Paragraph 2 most probably mean? A. Clean. B. Dry. C. Pollute. D. Heat. 3. How much rainwater can green roofs absorb according to scientists? A. 50%. B. 60%. C. 70%. D. 80%. 4. Which of the following is NOT a benefit of green roofs mentioned in the text? A. Preventing street floods. B. Making the building heavier. C. Saving energy. D. Providing habitats for wildlife. 5. Why are students described as "excited to get their hands dirty"? A. Because they like playing in the mud. B. Because they prefer outdoor activities only. C. Because the classrooms are not clean. D. Because they enjoy the practical gardening work. 七、阅读并回答问题 Qing Shan City is a small city in China that has become famous for its efforts in environmental protection. The local government and citizens work together to keep their home clean and green. One of the most important rules in the city is about waste sorting. Every household has three different colored bins: blue for recyclables like paper and bottles, green for kitchen waste that can be turned into compost, and gray for other trash. At first, people found it difficult, but now most residents do it without thinking. Another big change happened last year when the city banned single-use plastic bags in supermarkets and shops. Instead, people bring their own cloth bags or use paper bags. The city also encourages everyone to drink from reusable cups. As a result, the streets are much cleaner, and there is less plastic pollution in the rivers. The city also plants trees every spring. Last year, volunteers planted over 10,000 trees to make the air fresher. Now, birds and small animals are returning to the city parks. Qing Shan City shows that if everyone tries a little, the whole place can become much greener. 回答下面五个问题，每题答案不超过5个词。 1. What color bin is for kitchen waste? 2. What did the city ban last year? 3. What do people use instead of plastic bags? 4. How many trees were planted last year? 5.
