My father worked online all day, so he didn't produce any paper waste except paper napkins.He made the least rubbish in our family.

My mother cooked and produced plenty of kitchen waste, such as vegetable leaves, eggshells and food bags. What's worse, we couldn't eat up all the food of the dinner that day. So leftovers couldn't be avoided. It was not easy for mom to deal with all the rubbish, but she found a way to put it all into the bottle. How amazing!

My sister, a 16-year-old student, was busy preparing for her exams. She had to use paper to work out math or physics problems. She used only one side of the paper in the past. But from then on, she tried to use both sides of the paper because she realized we were challenging ourselves.She did a good job!

I was different from my sister. I love snacks and drinks. So my rubbish was almost from them. I was highly alert (警觉的) that I must produce less waste. I had fewer snacks or drinks. It was too difficult, but I did it! I've learnt a lot from this activity. I realize that everyone can produce less rubbish. We should start with small actions to protect the earth!

Dinosaur Provincial Park, Canada

The park is best known for its extensive fossil beds, within which 35 species of dinosaurs from about 100 to 65 million years ago have been identified. There are also fossilized remains of fish, reptiles, and amphibians. The area was listed as a UNESCO World Heritage site in 1979.

Salonga National Park, Congo

This is the largest reserve in Congo, covering more than 14,000 square miles. The park was established in 1970. The thick forest provides habitats for various animals like parrots, elephants and monkeys. Park visitors observe the animals from motorized river boats. The park was entered into the list of UNESCO World Heritage sites in 1984.

Hadrian's Wall, England

This is a Roman barrier that guarded the border of Britain. Hadrian (ruled 117-138 CE) went to Britain in 122 and was the first to build a wall, 80 miles long, to separate the Romans from the barbarians (野蛮人). There was no intention of fighting from the wall top; the soldiers there were trained to encounter the enemy in the open. In 1987, Hadrian's Wall was recognized by UNESCO as a World Heritage site.

Easter Island, Chile

This place is famous for its huge stone statues. The first European visitors, the Dutch, named it Easter Island in memory of their day of arrival. The small and hilly island was formed by volcanoes. Easter Island was added to UNESCO's World Heritage List in 1995.

With the development of network, distance learning is gaining more popular. People's opinions about it varies from one to another. In my opinion, it won't replace with traditional learning. Firstly, it isn't suitably for students who prefer direct communication with teachers. What's bad, studying online too long will do harm to students' eyes. However, it is its flexibility in time and place which benefits teaching and learning. Also, it releases teachers from repeat the same contents since the video or audio materials can played repeatedly. So it is a effective addition to traditional learning.

Briefly, the combination of distance learning and traditional learning can help students realize their potential when putting into practice.

Three million years may seem like a long time. But when you consider that planet Earth is more than 4. 5 billion years old, it is a pretty short period of time.

The blue whale,(weigh) more than even the biggest dinosaurs, is the largest animal has ever lived. They can grow to 30 meters long and be as heavy as 130, 000 kilograms. But for millions of years, they were not nearly that large, scientists said. "All of a sudden — ‘boom' — we see(they) get very big," said scientist Nick Pyenson. He and other (researcher) recently published an article on whale size. "It's like going from whales the size of minivans (面包车) to longer than two school buses," Pyenson added.

The scientists believe caused whales to get so large was a change in the Earth's climate only about 3 million years ago. This change led to food becoming more(easy) available. oncoming ice age made the ocean water cold and(bring) more nutrients, resulting in more food for large whales. Whales which were able to quickly-eat a lot of food survived, and got (large). "Over the next three or four million years, the blue whales grew 10 times bigger than they(be)," the scientists said.

Also, the black walnut produces a chemical substance (物质) through its roots as a4 strategy, which is poisonous to several common plants.

There have been many new plant varieties I brought home with5 that the walnut would6 accept them, but they all failed to grow well.

Give a hug. Hugging someone shows your affection and care. This can make them feel relaxed and open to you. This can also help them recognize that you are there to help them go through this moment. With no kind and loving words, your actions have already said a lot.

Now, go on and say some kind words. Words like "I'm here", "we are in this together", "you'll get over this", "lean on me" and so on, can help a sad person feel better and know that you're there to take him/her through the sad moment.

Use the right tone of voice. They go along with tone to convey a meaning to the listener. To convey your words with faith that would create a positive effect on the sad person, you would need to say it with the right tone of voice.

Listen patiently. People ask lots of questions but they end up paying little attention to getting the feedback (反馈) that they wanted. Don't be that person. After asking the questions, listen patiently to know what the sad person would appreciate at that time.

A. Say kind loving words.

B. Make use of polite expressions.

C. Then choose to appreciate others too.

D. Remember that words do not stand alone.

E. It will help you know how to offer the best fitting help.

F. This knowledge is gained through research and practice.

G. When you do this to someone, they can feel your warmth.

Sebastian Krigel and colleagues asked ChatGPT multiple times whether it is right to sacrifice (牺牲) the life of one person in order to save the lives of five others. They found that ChatGPT wrote random statements arguing both for and against sacrificing one life, indicating that it is not biased towards a certain moral stance (立场).

The authors then presented 767 U. S. participants, who were on average 39 years old, with a dilemma whether to sacrifice one person's life to save five others. Before answering, participants read a statement provided by ChatGPT arguing either for or against sacrificing one life to save five. Statements were from either a moral advisor or ChatGPT. After answering, participants were asked whether the statement they read influenced their answers.

Eighty percent of participants reported that their answers were not influenced by the statements they read. However, the authors found that the answers participants believed they would have provided without reading the statements were still more likely to agree with the moral stance of the statement they did read than with the opposite stance. This indicates that participants may have underestimated the influence of ChatGPT's statements on their own moral judgments.

The authors suggest that the potential for chatbots to influence human moral judgments highlights the need for education to help humans better understand artificial intelligence. They propose that future research should design chatbots that either decline to answer questions requiring a moral judgment or answer these questions by providing multiple arguments and warnings.

The paint was developed by Purdue mechanical engineering professor Xiulin Ruan and his team. It works through a passive cooling technology that offers great promises to reduce space cooling cost and global warming. "When we started this project seven years ago, we had saving energy and fighting climate change in mind," Ruan said in a podcast (播客) episode of This Is Purdue. They wanted to create a paint that would reflect sunlight away from a building, dramatically decreasing the need for air conditioning.

Heating, cooling, and lighting account for 28 percent of the world's total greenhouse gas emissions. And overusing air conditioning can overwhelm a city's power grid and cause blackouts (停电). In a Queens blackout in 2006, 175,000 people were left without power, which lead to 40 deaths. This paint could effectively be an alternative to air conditioners in some places.

The paint reflects 98.1%of solar radiation while also giving out infrared (红外线的) heat. Because the paint takes in less heat from the sun than it gives out, a surface coated with this paint is cooled below the surrounding temperature without using power. Covering a roof area of 1,000 square feet with the paint could create 10 kilowatts ofcooling power, the researchers found."That's more powerful than the air conditioners used by most houses,"Ruan told This Is Purdue.

You can't buy the paint just yet, but researchers are partnering with a company to put the paint on the market. While individual action to fight elimate change can help save our planet, it's important to note that the vast majority of the world's greenhouse gas emissions can be traced back to 100companies. Maybe we can douse(浇) those companies with this white paint, too — it could be worth a shot.

One of the very earliest way-marks discovered is in Cumbria. Dating from Roman times, it had lain fallen until 1836, when a farmer ploughing his fields came across a sandstone shaft (碑文). There are other stone posts that have stood by roadsides for centuries. It wasn't until 1697 that an act was passed declaring that guide-stones must be built.

This applied to remote parts of the country where there might be confusion as to which path led to the nearest market town. Later, with the appearance of the Royal Mail, the number rose still further. Nowadays many of these early road signs are designated (指定) as Listed Monuments.

"How times change!" Lucy, an enthusiastic walker, to whom I loaned the book, exclaimed.

"I suppose now we all rely far more upon mobile phones to guide us."

"Yet they aren't perfect. Whenever I go out, I prefer a map. I never have to worry about running out of battery." "I'm always grateful to whoever is placing way-markers along the route," she added, "I suppose that however sure we are, a little outside confirmation is always welcome."

Lucy is quite right there. Life itself can offer us a great many choices of path, and sometimes it isn't easy to know if we've chosen the best one.

Perhaps when it comes to gratitude, we should also include thanks for those people who appear in our lives when we most need them — either giving us gentle warning that we might be heading in the wrong direction, or reassurance that we are on the right track. After all, we'd be lost without them!

Death Valley, California, USA

Very lively at night but completely dead during the day, this place is nothing but dry hot desert. It actually holds the record for the hottest air temperature. It has an average temperature of 46℃ but it has reached 56.7℃ in 1913 and is considered to be a current record. As the driest place in the USA, this place is actually inhabited even though less than a thousand people live there.

Kebili, Tunisia

Tunisia's close location to the Mediterranean Sea suggests that it should be nice and cool but Kebili is a desert town which has the highest temperature recorded at 55℃. The people inhabiting the area have adjusted to tough conditions and learned to spend most of their time in the shade. Date palms are one of the key features of this place.

Wādī Halfā, Sudan

The city is located on the shores of Lake Nubia, and dust storms are a pretty common thing in the summer. With an average temperature of 41℃, it still managed to make it to 53℃ in 1967. You would think that it should be a little bit cooler for it is the most northern place in Sudan.

Dasht-e Lut Desert, Iran

It's another uninhabited desert which is actually getting super hot. In the past 20 years, the temperatures of 70℃ have been recorded. The salt desert spreads over 200 miles and even wildlife is not that spread. The place is popular with tourists and naturalists who would like to experience extreme landscapes.

The Historical Figure in China

_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

When Tom transferred from his rural middle school to a bustling city high school, he faced a crushing academic gap. Raised in a village where math lessons focused on basic addition and subtraction, Tom felt utterly unprepared for the city school's rigorous curriculum. Algebra equations and geometric theorems seemed like a foreign language. His first math test — a humiliating 42/100 — left him paralyzed with shame. "I'll never catch up," he thought, feelingoverwhelmed and avoiding eye contact with classmates who scored effortlessly in the 90s.

Ms. Liu, a patient and observant math teacher, recognized Tom's silent struggle. After class, she handed him a neatly printed practice sheet. "Let's tackle this step by step," she said. For the next three months, Ms. Liu dedicated two afternoons weekly to one-on-one tutoring. She broke complex problems into visual diagrams, comparing algebraic variables to "missing puzzle pieces" and geometric angles to "folded paper edges." To help him memorize formulas, she created catchy mnemonics (助记符，顺口溜), like "All Students Take Coffee" for trigonometric (三角函数) ratios. Additionally, she invited Tom to join her after-school study group, where peers shared problem-solving shortcuts in a judgment-free zone.

Tom's determination matched his teacher's effort. He transformed every spare moment into a learning opportunity: reviewing flashcards during his hour-long bus commute, solving practice problems during lunch breaks, and rewriting notes until his hands cramped. Each evening, he emailed Ms. Liu his homework drafts, and she responded with detailed corrections by dawn. Progress was painfully slow—his next test climbed to 65, then 78 — but Tom clung to Ms. Liu's mantra: "Small steps still move mountains."

The turning point arrived when Ms. Liu surprised him with an application for the Regional Math Olympiad. "You're ready," she insisted, though Tom doubted himself. For weeks, he drilled past competition papers, often working past midnight. On the day of the event, his palms sweat as he faced the first algebra problem, but Ms. Liu's voice echoed in his mind: "Focus on what you know." When results were announced, Tom's name appeared under "Honorable Mentions" — an achievement he'd never imagined possible.

At the award ceremony, Tom clutched (紧握，抱紧) his certificate, tears blurring the stage lights. "Ms. Liu didn't just teach me math," he told the crowd, his voice trembling. "She showed me that failure is just the first draft of success." The applause from classmates and teachers cemented a truth Tom now embraced: perseverance could bridge even the widest gaps.

Recent studies reveal an intriguing paradox: individuals who prioritize personal fulfillment over external validation report 37% higher life satisfaction. Take Dr. Maya Lin for an example: she was a scientist who abandoned a lucrative corporate career to research renewable energy in rural communities. Though her income dropped significantly, she described her work as "a daily discovery of purpose." Thisaligns with psychologist Abraham Maslow's theory that self-actualization — not basic needs — defines peak human experiences.

Cultural perspectives further complicate this discussion. In Eastern traditions, Confucianism emphasizes contributing to societal harmony. A 2024 survey showed 68% of Japanese youth view "fulfilling family duties" as central to life value, contrasting with Western emphasis on individualism. Yet Martin Luther King Jr.'s famous words —"Life's most urgent question is: what are you doing for others?" — bridge this gap, proposing that personal growth and social responsibility are inseparable.

Ultimately, defining life value requires balancing three elements: self-awareness, contribution to others, and adaptability in changing circumstances. As technology accelerates societal shifts, the ability to redefine one's purpose may become humanity's greatest wealth.

Artificial Intelligence Revolutionizing Farming

The integration of artificial intelligence (AI) into agriculture is transforming traditional farming practices, offering innovative solutions to challenges like climate change, labor shortages, and food security. Here are key applications of AI in modern agriculture:

Precision Farming

AI-powered sensors and drones collect real-time data on soil moisture, nutrient levels, and crop health. Machine learning algorithms analyze this data to optimize irrigation, fertilizer use, and pest control. For example, a farmer in California reduced water usage by 30% using AI-guided irrigation systems.

Crop Disease Detection

AI image recognition tools can identify plant diseases early by analyzing photos of leaves or fruits. A study by the University of Tokyo showed that AI systems achieved 98% accuracy in detecting tomato blight, far surpassing human capabilities.

Autonomous Farming Equipment

Self-driving tractors and harvesters equipped with AI navigate fields, plant seeds, and harvest crops with minimal human intervention. These machines use GPS and computer vision to avoid obstacles and ensure precise operations.

Yield Prediction

By processing historical data, weather patterns, and satellite imagery, AI models predict crop yields months in advance. This helps governments and organizations plan food distribution and prevent shortages. In India, AI-based predictions helped farmers increase wheat production by 15% in 2024.

Livestock Monitoring

Wearable AI devices track animal health, detecting illnesses or stress through changes in movement, temperature, or vocalizations. Dairy farms in the Netherlands reported a 20% drop in cattle mortality after adopting AI monitoring systems:

Despite its benefits, we must bevigilant of challenges AI adoption faces, such as high initial costs and the need for digital infrastructure in rural areas. However, as technology becomes more accessible, AI is poised (保持) to play a vital role in sustainable agriculture.

Their friendship once thrived on mutual trust. In freshman year, Leo taught Jay calculus under the bleachers when bullies mocked his learning disability. Last winter, Jay spent nights debugging Leo's programming errors before a critical demo. But senior year's pressure warped (扭曲) their teamwork into silent competition.

The competition's first round proved disastrous. A glitch (小毛病) caused their rover to spin wildly, drawing judges' frowns. During the lunch break, Jay found Leo hunched over a notebook, sketching (简述) a circuit (电路) diagram with familiar intensity — the same focus he' d once used to explain quadratic equations. "I found the bug," Leo muttered, circling a sensor code. "Your redesign ignored terrain friction variables (地球摩擦变量)."

Swallowing pride, Jay whispered, "I should've asked for help." Leo's pen paused. "And I should've told you I was taking night shifts to pay for college apps." Their eyes met, acknowledging unspoken fears.

They worked through the break, combining Jay's efficiency algorithms with Leo's mechanical insights. When their rover flawlessly climbed the final obstacle course slope, the applause mattered less than Leo's fist bump — a gesture revived from their freshman year.

That evening, Jay scribbled in his journal "Friendship isn't a solo sprint (冲刺) but arelay race— sometimes you carry the baton (接力棒), sometimes you pass it." Psychologists affirm this observation; a 2024 MIT study found teams balancing trust and accountability outperform purely competitive groups by 63%. True friendship, the data suggests, thrives not in perfect harmony but in the courage to bridge vulnerabilities.

Earthquakes can strike without warning, making preparation crucial. As students, understanding proper safety measures can protect lives during such emergencies. Here's a step-by-step guide to staying safe before, during, and after an earthquake.

Before an Earthquake

Build an Emergency Kit: Include a flashlight, bottled water, non-perishable food, a first-aid kit, a whistle, and spare batteries. Store it in an accessible location. Learn Safe Zones: Identify sturdy furniture (e. g., desks. or structural supports (e. g., load-bearing walls. in classrooms. Avoid windows or heavy objects that may fall. Practice Drills: Participate in school earthquake drills to react quickly. Familiarize yourself with evacuation routes and assembly points.

During an Earthquake

/ Drop, Cover, and Hold On:

/ Drop to your hands and knees to avoid being knocked over.

/ Cover your head and neck under a desk or table. If no shelter is nearby, crouch near an interior wall.

/ Hold On to your shelter until shaking stops.

/ Stay Indoors: Do not run outside during shaking. Falling debris poses a major risk.

/ Avoid Hazards: Stay away from shelves, glass, or hanging objects.

After an Earthquake

Evacuate Safely: Exit the building calmly once shaking stops. Use stairs, not elevators, in case of off power.

Check for Injuries: Assist others if safe to do so. Report serious injuries to teachers or emergency responders.

Avoid Damaged Areas: Do not re-enter buildings until authorities declare them safe.

Stay Informed: Listen to a battery-powered radio for updates from official sources.

Remember: Panic worsens emergencies. Staying calm and following protocols greatly improves survival chances. Share this knowledge with peers to build a safer community.
