主题：跨越代沟的环保行动（Environmental Action Across Generations）
题源说明：本文为原创试题，素材参考中国乡村环境治理报道（如福建多地“婆婆妈妈”志愿队、农村垃圾分类推广等）
字数：约340词
Last summer, I volunteered for a local environmental group in a remote village in Fujian. My task was to promote waste sorting among the elderly residents. I had imagined it would be a simple job—handing out flyers and explaining the benefits. However, the reality was far more challenging than I had anticipated.
The villagers, most of whom were over sixty, lived a frugal（节俭的） life shaped by decades of scarcity. To them, throwing away plastic bottles or old clothes was not "wasteful," but rather a betrayal of their hard-earned resources. When I tried to explain the concept of "landfill pollution," they looked at me with confusion and a bit of skepticism. One old man, Grandpa Lin, even told me bluntly, "Young lady, we survived hardships you cannot imagine. Don't lecture us about rubbish."
I felt frustrated and helpless. Standing in the narrow alley, I realized that my textbook knowledge was useless here. I needed a different approach. Instead of talking about "carbon footprints," I started helping them repair broken bamboo baskets and showed them how to turn kitchen waste into fertilizer for their vegetable gardens. I listened to their stories about how they used to reuse everything during the famine years.
Gradually, the atmosphere changed. Grandpa Lin, who had initially rejected me, began to invite me for tea. He even organized a small group to help me collect recyclables. By the end of the month, the village had established its first waste-sorting corner. More importantly, I had bridged the gap between modern environmental theory and traditional wisdom. I learned that true environmental protection is not just about changing habits, but about respecting people's lives and histories.
4.What was the author’s initial expectation of the volunteer job
A. It would be a demanding and complex task.
B. It would be an easy job of distributing leaflets.
C. It would involve building relationships with the elderly.
D. It would require professional knowledge of chemistry.
5.Why did the villagers resist the idea of waste sorting at first
A. They were unfamiliar with modern technology.
B. They believed recycling was a waste of time.
C. They associated discarding items with past hardships.
D. They preferred to keep their village dirty.
6.How did the author finally manage to persuade the villagers
A. By giving speeches on environmental science.
B. By forcing them to follow the rules strictly.
C. By connecting environmental ideas with their traditional values.
D. By offering them financial rewards.
7.Which of the following best describes the author’s journey in the village
A. A frustrating failure.
B. A cultural misunderstanding.
C. A growing process of mutual respect.
D. A conflict between generations.

主题：全球绿色行动与可持续发展的挑战

字数：约 390 词
Global Green Actions for a Sustainable Future
While global leaders gathered in Geneva last month to discuss ambitious climate targets, a new report from the Global Sustainability Indexhas cast a shadow over the optimism. The report reveals a widening gap between political rhetoric and the slow pace of actual implementation on the ground. Although investments in green technology are breaking records, the planet’s temperature continues to climb.
According to the data, renewable energy sources like wind and solar are growing faster than ever. In Europe, solar power capacity increased by 25% last year, and electric vehicle sales have doubled. However, the report points out that this growth is dangerously uneven. Developing countries, particularly in Southeast Asia and Africa, often lack the necessary funds and technology to build large-scale green infrastructure. As a result, they continue to rely heavily on coal and oil to fuel their economic growth. "We are seeing a split world," says Dr. Kenji Tanaka, an economist at the report. "The rich get greener, while the poor are left with the bill."
Another major challenge highlighted is "greenwashing." Many large corporations claim to be "carbon neutral" by buying cheap carbon credits from forest conservation projects abroad, rather than reducing emissions from their own factories. Scientists criticize this practice, arguing that it creates an illusion of progress while the planet continues to heat up. "We cannot buy our way out of the climate crisis," says Dr. Elena Rodriguez, a lead researcher. "Real change requires cutting emissions at the source."
espite these setbacks, the report highlights successful local initiatives that offer hope. In Kenya, a partnership between the government and local communities has successfully combined wildlife protection with solar power generation, providing both jobs and clean energy. Similarly, Costa Rica’s policy to pay landowners for preserving forests has restored biodiversity and boosted eco-tourism. These examples prove that practical, well-funded actions can work. The report concludes that international cooperation must move beyond empty promises and focus on providing real financial support to ensure a "just transition" for all nations.
8.What is the main purpose of the first paragraph
A. To introduce a new climate agreement signed in Geneva.
B. To highlight the contradiction between promises and reality.
C. To explain why renewable energy is growing so rapidly.
D. To criticize the economic policies of developing countries.
9.What does the underlined word "greenwashing" in Paragraph 3 probably mean
A. Making misleading claims about being environmentally friendly.
B. Investing heavily in new green technologies and innovations.
C. Cleaning up polluted industrial sites and rivers.
D. Planting trees to absorb carbon dioxide from the air.
10. According to Dr. Elena Rodriguez, what is the fundamental solution to the climate crisis
A. Buying more international carbon credits.
B. Shifting entirely to renewable energy sources.
C. Cutting emissions directly at the source.
D. Cooperating with large multinational corporations.
11.Why does the author mention Kenya and Costa Rica in the last paragraph
A. To illustrate the uneven distribution of global wealth.
B. To provide evidence of successful local green actions.
C. To compare different approaches to wildlife protection.
D. To explain why solar power is more popular in Africa.

主题：蓝色碳汇（Blue Carbon）—— 被忽视的海洋固碳力量
When we talk about fighting climate change, images of vast forests usually come to mind. Trees are indeed vital "carbon sinks," absorbing carbon dioxide from the atmosphere. However, scientists are increasingly pointing to a less visible but far more efficient ally beneath the waves: Blue Carbon.
Blue carbon refers to the carbon captured and stored by coastal and marine ecosystems, specifically mangroves, tidal marshes, and seagrass meadows. While these "blue forests" cover less than 2% of the seafloor, they are responsible for absorbing nearly half of the total carbon buried in the ocean each pared to terrestrial forests, which store carbon in wood and soil for decades or centuries, coastal blue carbon ecosystems can lock carbon away in deep sediments for thousands of years. This makes them a critical weapon in the fight against global warming.
Beyond carbon storage, these ecosystems provide essential services. Mangrove forests act as natural barriers, protecting coastal communities from storm surges and erosion. Seagrass meadows improve water quality by trapping sediments and releasing oxygen. Yet, despite their importance, these habitats are disappearing at an alarming rate—up to three times faster than tropical rainforests. The primary drivers are coastal development, pollution, and destructive fishing practices. When these ecosystems are damaged, the massive amounts of carbon stored in their soils are released back into the atmosphere, turning a climate solution into a source of emissions.
Recognizing this, a new movement called "Blue Carbon Finance" is emerging. Countries like Indonesia and Australia are creating markets where companies can invest in restoring mangroves to offset their emissions. For instance, a project in Kenya’s Mikoko Pamoja has successfully sold carbon credits to fund local schools and clinics. This model demonstrates that environmental protection and economic development can go hand in hand. Nevertheless, challenges remain. Measuring the exact amount of carbon stored in underwater sediments is technically difficult, and ensuring that local communities benefit fairly from these projects requires careful governance. The race to save our blue planet is not just about planting trees; it is about saving the roots beneath the sea.
12.What is the main purpose of Paragraph 1 and 2
A. To introduce a new concept and explain its mechanism.
B. To compare the sizes of different forest ecosystems.
C. To criticize the inefficiency of traditional carbon sinks.
D. To describe the beauty of coastal landscapes.
13.According to the passage, what is a unique advantage of Blue Carbon ecosystems
A. They cover more than half of the Earth's surface.
B. They can store carbon for thousands of years underground.
C. They grow faster than any terrestrial plants.
D. They are easier to restore than tropical rainforests.
14.What does the author suggest about "Blue Carbon Finance"
A. It focuses solely on punishing polluting companies.
B. It has completely solved the problem of coastal erosion.
C. It links environmental restoration with community benefits.
D. It discourages investment in renewable energy.
15.Which of the following is the best title for the text
A. The Disappearance of Coastal Wetlands
B. Blue Carbon: The Ocean's Secret Weapon Against Climate Change
C. How to Invest in Green Energy Projects
D. The Comparison Between Trees and Seaweed

主题：亲近自然是最好的减压药（Nature: The Best Stress Reliever）
How Nature Helps Teens Beat Stress
Being a teenager today is stressful. With academic pressure, social media anxiety, and uncertain futures, many young people feel exhausted. While therapy and medication are common solutions, there is a simpler, cheaper, and more effective remedy available to everyone: spending time in nature. 16
It calms the nervous system.
When you walk into a forest or sit by a lake, your body relaxes. Studies show that exposure to natural environments lowers cortisol (the stress hormone) levels. 17 Your heart rate slows down, and your breathing becomes deeper. It is like hitting a reset button for your brain.
It improves focus and creativity.
Modern life bombards us with screens and notifications, which fragment our attention. Nature provides a soft fascination. 18 This allows your directed attention to rest, improving your ability to concentrate when you return to your studies. Many famous thinkers, including Einstein, credited their best ideas to moments spent walking alone in nature.
It builds resilience.
Spending time outdoors often involves unpredictable elements, like sudden rain or a steep hill. 19 Learning to adapt to these small discomforts teaches you that you can handle unexpected changes in life. You realize that you are stronger and more capable than you thought.
It fosters connection.
Social media often makes teens feel isolated and inadequate. In nature, these barriers fall away. 20 Whether you are hiking with friends or volunteering for a tree-planting project, sharing experiences in nature helps you form deeper, more authentic bonds.
So, put down your phone, step outside, and let nature do its magic. Your mind and body will thank you.
A. It is a powerful tool for mental health.
B. Overcoming these challenges builds confidence.
C. Your muscles loosen, and your mind stops racing.
D. Nature offers a break from the noise of daily life.
E. It is much easier to talk to someone while walking side by side.
F. Doctors suggest that teens spend at least two hours a week outdoors.
G. The beauty of nature distracts you from your worries and fears.

主题：我的一个月“绿色生活”挑战
My One-Month Green Life Challenge
I used to think environmental protection was something only scientists or politicians worried about. As a college student, I was too busy with assignments and social life to care about my 21 footprint. However, an article in Reader’s Digest challenged me to try a "Green Life" for a month. Curious but 22, I accepted, thinking it would be easy.
The first week was a 23. I tried to cut down on single-use plastics. I carried a reusable water bottle and a cloth bag everywhere. Once, I 24 a convenience store to buy a drink, only to find I had left my bottle at home. I stood there, 25 whether to buy a plastic one or go thirsty. Finally, I chose to go thirsty. It was a small 26, but it made me realize how deeply convenience had taken root in my life.
Over the next few weeks, I started biking to campus instead of taking the bus. I also began to 27 food labels, avoiding products with excessive packaging. My roommates laughed at my "hippie" habits, but I didn't 28. Slowly, I noticed changes. Not in the world, but in me. I felt more 29 and connected to my surroundings. The constant rush slowed down, and I started noticing the changing colors of the leaves on my bike ride.
By the end of the month, the challenge was over, but my new habits weren't. I realized that living green isn't about being perfect; it's about making better 30 when we can. It is not a burden, but a way to live a more mindful life. The biggest 31 was not just the reduction of waste, but the shift in mindset. Previously, I saw environmental protection as a 32 list of "don'ts"—don't use plastic, don't waste water. Now, I see it as a 33 way of living that brings joy and purpose. I may not save the planet alone, but I can 34 a difference, one day at a time. And that realization is the most 35 gift of all.

The Empty Mountain
When Dad told me we were going to Green Hill to plant trees for the summer vacation, I was totally against it. I was sixteen, and the last thing I wanted was to leave my video games and friends to sweat in the dirt of a barren mountain.
“You spend too much time indoors,” Dad said firmly. “You need to see what real work looks like.”Green Hill was exactly what its name suggested—green in name only. It was dry, dusty, and covered with rocks. The wind blew constantly, carrying sand that stung my face. The other volunteers were mostly local villagers, silent and serious. They treated me like a spoiled kid, which I probably was. I tried to slack off, pretending to dig holes while secretly playing games on my phone.
One afternoon, an old man named Mr. Zhang, the leader of the team, stopped me. He didn't scold me. Instead, he handed me a seedling（幼苗）. “This little guy needs a home,” he said, pointing to a shallow pit. “But the soil is too hard. It needs your hands to soften it.”
I looked at the fragile green stem and then at the rocky ground. I sighed and started digging. It was harder than it looked. My palms blistered（起泡）, and my back ached. But as I placed the seedling into the earth and covered its roots with soft soil, I felt a strange sense of calm.
That night, a sudden sandstorm hit. The wind howled like a wild beast, shaking our tents. I lay awake, worrying about the little trees we had planted. Would they survive the wind

参考范文
Dear Principal,
I am Li Hua, a member of the Green Campus Initiative Group. I am writing to express my concern about the severe waste on campus and offer some suggestions.
Although environmental protection is advocated, food waste in the cafeteria remains shocking. Besides, lights are often left on in empty classrooms, and disposable plastic utensils are overused.
To tackle these problems, I suggest setting up a "Clear Your Plate" campaign to raise awareness. Additionally, installing motion-sensor lights can effectively reduce electricity waste. I hope my suggestions will contribute to building a greener campus.
Yours sincerely,
Li Hua

Paragraph 1:
When the storm finally stopped at dawn, I rushed out of the tent. My heart sank as I looked at the mountain. Many of the seedlings we had carefully planted were gone, either broken or buried under the rocks. A wave of guilt washed over me. I remembered how I had slacked off and complained. Now, seeing the damage, I realized how much effort it took to heal even a tiny part of nature. Without hesitation, I grabbed a shovel and started to dig again. This time, I worked with all my strength, making sure the soil around the new trees was firm and deep.
Paragraph 2:
Mr. Zhang came up to me, patting me on the shoulder. He looked at the barren land and then at my blistered hands. “Nature is tough, kid,” he said with a smile. “But so are you.” His words warmed me more than the morning sun. I looked at the rows of tiny trees standing bravely against the wind. They were fragile, yet they held the hope of a green future. From that moment on, I was no longer a reluctant visitor. I was a protector of the Green Hill. I finally understood that real growth happens when we stop running from hard work and start caring for the world around us.
