Dear Ms. Jenkins,
I am writing to submit my article for the "Technology for a Greener Future" essay competition.
My article focuses on biodegradable plastics made from agricultural waste, such as corn stalks and rice husks. Unlike conventional plastics that persist for centuries, these materials decompose within six months under natural conditions, significantly reducing white pollution in soil and oceans. I illustrate how a startup in my city has replaced plastic packaging with these materials, cutting landfill waste by 40% annually.
I firmly believe that technology, when guided by ecological wisdom, offers powerful solutions to environmental crises. However, technology alone is insufficient—it must be combined with conscious consumption and policy support to create lasting change.
Yours sincerely,
Li Hua

Paragraph 1:
"This was my grandmother," she said, her voice barely audible. The photograph showed an elderly woman sitting at a wooden table, her fingers folding a paper crane with the same precision Lin Yue now possessed. "She was a sanitation worker for forty years. Every morning, she would leave a crane on the desk of the young environmental science teacher who helped her sort recyclables after school." Lin Yue's eyes glistened. "When I was eight, she told me that paper cranes carry souls to peaceful places. After she passed, I started folding them for you—because you remind me of him. You see the beauty in what others discard." Chen Wei felt his throat tighten. He looked at the cranes he had collected in a box under his bed, suddenly understanding their weight. They were not mere gifts; they were bridges between generations, between loss and hope, between a grandmother's gratitude and a girl's silent admiration.
Paragraph 2:
On the day of the competition presentation, Chen Wei and Lin Yue stood together before the judges. Their project—a comprehensive waste-to-resource system powered by student volunteers and smart sorting technology—glowed on the screen behind them. But instead of beginning with data, Chen Wei held up a paper crane. "This crane is made from last week's chemistry notes," he said. "It represents what we believe: that everything deserves a second life." Lin Yue stepped forward, her voice steady now. "My grandmother taught me that the smallest acts of care can span decades. Our project is not just about waste reduction. It is about seeing value in the overlooked, about building connections that outlast any competition." The judges were silent. Then one asked, "How will you sustain this beyond graduation " Chen Wei and Lin Yue exchanged glances, and in that moment, both knew the answer had already begun—with a paper crane, a shared purpose, and a promise to keep folding hope into every discarded thing.人教版高中英语选择性必修三

A篇
The Bamboo Weaver's Green Revolution
Seventy-two-year-old Wang Dexiang who lives in the misty mountains of Zhejiang, has spent fifty years weaving bamboo baskets. His calloused hands move with the precision of a musician, splitting strips, soaking them in stream water, and weaving them into containers that last decades. For generations, this craft became a way to earn modest income in a region with limited farmland.
But everything changed in 2019, Wang's grandson, Wang Jun, returned from university with an environmental science degree and a radical proposal: transform the family workshop into a zero-waste enterprise and make his Grandpa’s baskets revolutionary.
The revolution began with sourcing. Instead of purchasing bamboo from distant plantations, the Wangs established a community-managed grove using traditional agroforestry techniques. They planted nitrogen-fixing trees between bamboo clusters, eliminated chemical fertilizers, and harvested using lunar cycles—an ancient practice Wang's grandmother had taught him. Modern soil testing confirmed what tradition already knew: the grove's carbon sequestration exceeded industrial bamboo farms by 40%.
Next came design innovation. Jun collaborated with industrial designers to create modular baskets—containers with interchangeable components that could be repaired rather than discarded. When a handle wore out, customers replaced just the handle. When a base cracked, they swapped it for a new one. The old parts returned to the workshop for reweaving. "Your grandmother would mend clothes," Jun told his grandfather. "We're mending baskets for the same reason—respect for materials."
The most transformative change, however, was cultural. Wang began hosting workshops where urban visitors learned not just weaving techniques but the philosophy behind them. Participants’leaving with handmade baskets and a changed perspective on consumption is his sincere hope.
By 2024, the Wang workshop had trained forty young apprentices, diverted twelve tons of plastic containers from local markets, and inspired three neighboring villages to revive traditional crafts with environmental adaptations. Wang Dexiang tells audiences at regional environmental conferences ,"Technology gives us tools. But wisdom about living with nature—that comes from those who came before."
1. What initially motivated Wang Jun to transform the family workshop
A. The declining market for traditional bamboo products.
B. His environmental science background and belief in sustainability.
C. Government pressure to modernize rural industries.
D. Competition from cheaper plastic container manufacturers.
2. What does the underlined word "sequestration" in Paragraph 3 most probably mean
A. The process of capturing and storing atmospheric carbon.
B. The method of separating bamboo from other plants.
C. The technique of preserving bamboo strips in water.
D. The practice of selling bamboo at higher prices.
3. What is the main purpose of the modular basket design
A. To reduce production costs for the workshop.
B. To make baskets more fashionable for urban consumers.
C. To extend product lifespan and minimize waste.
D. To increase the variety of products available.
4. What can we infer about Wang Dexiang's attitude toward tradition and innovation
A. He believes tradition should remain unchanged.
B. He initially resisted change but later embraced the integration of tradition and modern environmental science.
C. He thinks modern technology is superior to traditional wisdom.
D. He regrets not adopting new methods earlier in his career.

Ancient Wisdom, Modern Crisis:
Traditional Ecological Knowledge in the Climate Era
Indigenous and traditional communities occupy approximately 22% of Earth's land surface, yet their territories contain 80% of the planet's biodiversity. This striking statistic, published in a 2024 Nature synthesis, has prompted renewed scientific interest in Traditional Ecological Knowledge (TEK)—the accumulated understanding of ecosystems developed over millennia through direct interaction with local environments.
TEK operates on fundamentally different principles from Western scientific ecology. While modern science often isolates variables in controlled experiments, TEK embraces complexity and interconnection. The Saami people of northern Scandinavia, for instance, recognize over 180 types of snow, each with distinct implications for reindeer herding, travel safety, and ecosystem health. This granular knowledge enabled them to detect climate changes decades before instrumental records confirmed warming trends.
In the Amazon basin, where deforestation threatens global climate stability, indigenous management practices offer proven alternatives to industrial agriculture. Research by the Woods Hole Research Center demonstrates that indigenous forest gardens—poly-culture systems mimicking natural forest structure—maintain soil fertility without chemical inputs for centuries. These "agroforestry mosaics" sequester 30% more carbon than monoculture plantations while supporting food security for local communities.
The integration of TEK into modern environmental policy, however, faces significant obstacles. Intellectual property systems often fail to protect communal knowledge, leading to "biopiracy" where corporations patent traditional plant uses without compensation. Furthermore, the oral transmission of TEK becomes threatened as younger generations migrate to urban centers. A 2023 UNESCO report estimated that one indigenous language—and its associated ecological knowledge—disappears every two weeks.
Some nations are pioneering solutions. New Zealand's Whanganui River was granted legal personhood in 2017, incorporating Maori concepts of reciprocal relationships between humans and nature into statutory law. Australia's Indigenous Protected Areas program combines traditional fire management with modern conservation science, reducing catastrophic wildfires while preserving cultural practices.
The path forward requires what researchers term "two-eyed seeing"—using the strengths of both Western science and traditional knowledge. As climate change accelerates, this integration may prove essential. The solutions we seek may already exist, preserved in languages we are only beginning to understand.
5. What is the passage mainly about
A. The history of indigenous communities in biodiversity hotspots.
B. The value, applications, and challenges of Traditional Ecological Knowledge in modern environmental protection.
C. The conflicts between Western science and traditional practices.
D. The economic benefits of biopiracy for corporations.
6. According to the passage, how does TEK differ from Western scientific ecology
A. TEK relies on written records while Western science uses oral transmission.
B. TEK focuses on complexity and interconnection rather than isolated variables.
C. TEK is less accurate than modern instrumental measurements.
D. TEK is only applicable in tropical rainforest environments.
7. What does the example of New Zealand's Whanganui River illustrate
A. The economic potential of river tourism.
B. A successful integration of traditional concepts into modern law.
C. The superiority of Western legal systems over indigenous governance.
D. The environmental damage caused by industrial agriculture.
8. What is the author's attitude toward the future of TEK in environmental policy
A. Entirely pessimistic due to rapid language loss.
B. Cautiously optimistic, provided integration efforts continue.
C. Dismissive of its practical value compared to modern technology.
D. Uncritical and overly enthusiastic about indigenous solutions.

Artificial Intelligence: Earth's New Guardian or Its Next Threat
In the race to address climate change, artificial intelligence has emerged as both a promising tool and a potential liability. On one hand, AI-powered systems are revolutionizing environmental monitoring, optimizing renewable energy grids, and accelerating the discovery of new materials for carbon capture. On the other hand, the computational infrastructure powering these systems consumes staggering amounts of electricity, generating carbon footprints that rival small nations.
The benefits are substantial and growing. Google's DeepMind has developed AI algorithms that reduce the energy consumption of data center cooling systems by 40%. Microsoft employs machine learning to forecast wind patterns with 20% greater accuracy, enabling more efficient turbine placement. In materials science, AI has identified novel catalysts for splitting water into hydrogen fuel—discoveries that might have taken human researchers centuries.
Yet the environmental cost of AI itself is escalating rapidly. Training a single large language model like GPT-4 requires electricity equivalent to the annual consumption of 120 average American households, emitting approximately 500 tons of CO . The global AI sector's energy demand is projected to increase tenfold by 2030, potentially consuming 3.5% of worldwide electricity—more than most countries.
This paradox has sparked intense debate among technologists and environmentalists. Some argue for "green AI"—developing more efficient algorithms, powering data centers with renewable energy, and prioritizing applications with the highest environmental returns. Others contend that AI represents a dangerous distraction, offering technological fixes for problems that require systemic social and political transformation.
The most nuanced perspective recognizes that AI is neither savior nor villain but a powerful tool whose impact depends entirely on human choices. Used wisely, AI can optimize global supply chains to eliminate food waste, predict extreme weather events with life-saving precision, and model complex climate scenarios that inform policy. Used recklessly, it can accelerate consumption, enable surveillance capitalism, and consume resources that might otherwise fund direct emissions reductions.
The critical question is not whether to use AI for environmental protection but how to govern its development. This requires international agreements on AI energy standards, transparent reporting of computational carbon footprints, and rigorous evaluation of whether each application delivers genuine environmental benefits or merely technological spectacle.
As we stand at this crossroads, we must remember that intelligence—artificial or human—is merely a capacity. Wisdom lies in how we choose to direct it. The algorithms we build today will shape the ecosystems our grandchildren inherit. We owe them careful, conscious design.
9. What does the author mean by calling AI "Earth's New Guardian or Its Next Threat"
A. AI will either protect the environment or destroy human civilization.
B. AI has the potential to either help or harm environmental efforts depending on how it is used.
C. AI is currently the biggest threat to global security.
D. AI guardians will replace human environmental scientists.
10. According to the passage, what is a major environmental concern about AI
A. AI algorithms are too complex for most people to understand.
B. The energy consumption and carbon emissions of AI training and operation.
C. AI systems frequently malfunction and cause industrial accidents.
D. AI replaces too many workers in the renewable energy sector.
11. What does the author suggest is the "most nuanced perspective" on AI
A. AI should be banned entirely to protect the environment.
B. AI is inherently good and will solve all environmental problems.
C. AI's impact depends on human choices and governance.
D. AI is less important than traditional conservation methods.
12. What is the author's main purpose in writing this passage
A. To promote specific AI products for environmental monitoring.
B. To argue that AI is too dangerous to be used for any purpose.
C. To present a balanced analysis of AI's environmental potential and risks.
D. To criticize technology companies for their energy consumption.
13. Which of the following would the author most likely support
A. Unrestricted development of all AI technologies.
B. International regulations on AI energy consumption and environmental applications.
C. Complete replacement of human scientists with AI systems.
D. Abandoning renewable energy in favor of AI-powered fossil fuel extraction.
D篇
Imagine a building that breathes like a tree, capturing carbon dioxide and releasing oxygen. A structure that heals its own cracks, adapting to stress like living tissue. A facade that changes color with the seasons, optimizing light absorption without mechanical systems. This is not science fiction—it is the emerging field of living architecture, where biotechnology and construction converge to create structures that function as ecosystems.
The concept draws inspiration from nature's 3.8 billion years of evolutionary engineering. Termite mounds, for instance, maintain remarkably stable internal temperatures despite extreme external conditions, using passive ventilation systems that human architects are only beginning to replicate. The Eastgate Centre in Zimbabwe, modeled on termite mound physiology, uses 90% less energy for climate control than conventional buildings of comparable size.
Recent breakthroughs have pushed biomimicry toward literal living systems. Researchers at the University of Colorado have developed "living concrete" using cyanobacteria—photosynthetic microbes that capture CO and produce calcium carbonate, essentially growing building material from sunlight and atmospheric carbon. Initial prototypes achieve compressive strengths suitable for non-load-bearing applications, with the remarkable capacity to self-heal minor cracks through continued bacterial metabolism.
Perhaps more revolutionary are "biofacades"—building skins incorporating algae or moss colonies. The BIQ House in Hamburg, completed in 2013, features transparent panels containing microalgae that generate biomass for energy while shading interiors from summer heat. Updated systems under development promise to capture more carbon annually than the building's construction and operation emit, achieving net-negative carbon performance.
The implications for urban sustainability are profound. Buildings account for 39% of global carbon emissions—28% from operational energy and 11% from materials and construction. Living architecture addresses both simultaneously: reducing operational energy through biological processes and sequestering carbon in structural materials. A 2024 study estimated that widespread adoption of bio-based building materials could offset 15% of global construction emissions by 2050.
Challenges remain substantial. Living materials require moisture and nutrients, creating durability concerns in harsh climates. Building codes developed for inert materials struggle to accommodate biological systems. And public acceptance of "growing" buildings lags behind technological capability.
Yet the trajectory is clear. As climate targets tighten and material science advances, the boundary between building and organism will continue to blur. The cities of the future may not merely contain green spaces—they may themselves be alive.
14. What does the underlined word "biomimicry" in Paragraph 2 most probably mean
A. The study of ancient building techniques.
B. The imitation of natural systems and processes in human design.
C. The use of biological weapons in military architecture.
D. The preservation of endangered species in urban environments.
15. What makes the "living concrete" developed by University of Colorado researchers special
A. It is completely transparent like glass.
B. It uses bacteria to grow building material from CO and can self-heal.
C. It is the strongest building material ever created.
D. It changes color depending on the weather.
16. What is the main advantage of biofacades mentioned in the passage
A. They are cheaper than traditional building materials.
B. They can achieve net-negative carbon performance.
C. They require no maintenance whatsoever.
D. They are completely fireproof.
17. What challenge does living architecture currently face
A. There is no scientific basis for the technology.
B. Building codes are not adapted to biological building materials.
C. The public is overly enthusiastic about the technology.
D. Living materials are too heavy for most structures.
18. What is the best title for this passage
A. The History of Green Building Design
B. Living Buildings: Architecture That Breathes and Grows
C. Why Traditional Concrete Is Superior to New Materials
D. The Economic Costs of Sustainable Construction

Digital Detox for the Planet: Rethinking Our Screen Time
The environmental impact of digital technology extends far beyond the electricity powering our devices. Every email sent, video streamed, and cloud photo stored contributes to a vast, invisible infrastructure with a surprisingly substantial carbon footprint. 　19　
Data centers—massive warehouses of servers processing our digital lives—consume approximately 1% of global electricity, a figure projected to rise to 8% by 2030. These facilities require constant cooling, often using water-intensive systems in regions already facing scarcity. 　20　
The manufacturing of devices presents equally troubling statistics. Producing a single smartphone generates 85 kilograms of CO and requires mining rare earth elements that devastate local ecosystems. 　21　 Yet the average user replaces their phone every 2.5 years, driven by planned obsolescence and marketing rather than genuine need.
What can individuals do The answer is not to abandon technology but to use it more intentionally. 　22　 For cloud storage, regularly deleting unnecessary files reduces server load. For devices, extending usage to five years or more dramatically reduces lifetime environmental impact per user.
Systemic changes are equally crucial. Tech companies must transition to renewable energy for data centers and design products for longevity and repairability. 　23　 Some European nations now require "right to repair" legislation, ensuring consumers can fix devices rather than replace them.
A. Streaming video accounts for nearly 60% of global internet traffic.
B. Consumers should demand longer product lifespans from manufacturers.
C. For video consumption, choosing lower resolution reduces data transmission energy.
D. The problem lies not in technology itself but in how we consume it.
E. A single data center can consume as much water as a city of 50,000 residents.
F. The average laptop requires even more resources to produce than a smartphone.
G. Digital technology has revolutionized education and communication worldwide.

"When the glacier 'sweats'—releases meltwater prematurely—the Naxi elders know the mountain is 　31　," Dr. Li noted. "Modern sensors confirm what their observations predicted weeks earlier."
This collaboration has yielded unexpected insights. Naxi oral histories described a "white dragon" that periodically emerged from the glacier, which scientists initially 　32　 as mythological fantasy. Further investigation revealed that the "dragon" was actually a periodic glacial surge—a rapid advance followed by retreat—that occurred approximately every 80 years. This 　33　, previously unknown to glaciology, has now been incorporated into predictive models.
The documentary project, funded by an international climate foundation, aims to 　34　 both the scientific urgency and cultural significance of the melting glaciers. Dr. Li hopes it will inspire action beyond academic circles. "Science gives us the 　35　," she says. "But culture gives us the reason to care. Without both, we won't act fast enough."
Local responses have been mixed. Tourism operators fear that 　36　 the glacial retreat will discourage visitors. Some Naxi elders worry that excessive attention will 　37　 the spiritual sanctity of the mountains. Yet younger community members, trained by Dr. Li as citizen scientists, have become passionate 　38　 for conservation.

Sixteen-year-old Chen Wei would find a paper crane on his desk every spring, when cherry blossoms painted the old campus pink. No note, no signature . For three years, since middle school, this mysterious ritual had continued, and Chen Wei had never discovered who left them.
He suspected Lin Yue, the quiet girl who sat two rows behind him in environmental science club, often watched him with an expression he couldn't decipher. But whenever he approached her, she would bury her face in a book about renewable energy or disappear into the school's recycling station, where she spent hours sorting waste with obsessive precision.
Chen Wei appreciated the cranes, though he never understood their meaning. He was the school's "trash king"—a nickname he wore with pride. While other students saw garbage, he saw resources. "Waste is just resources in the wrong place" ,he quoted his father’s words. Although he knew Lin Yue shared his passion ,she remained distant, communicating with him only through data sheets and occasional nods during club meetings.
The spring of their senior year brought change. The city announced a "Zero Waste Campus" competition, offering funding for the most innovative student environmental project. Chen Wei proposed an ambitious plan: converting the school's entire waste stream into reusable resources within one semester. He needed a partner. He needed Lin Yue.
He found her in the recycling station, as expected, separating aluminum from steel with gloved hands. "I know about the cranes," he said, though he didn't. Her hands paused. "And I need your help with the competition. But more than that, I want to understand why you keep folding them."
Lin Yue was silent for a long moment. Then she reached into her bag and pulled out a worn photograph.
