Despite these impacts, the problem appears overlooked by the tech industry. "If you examine tech companies' sustainability reports, they mention carbon emissions (碳排放) and water use, but completely ignore harmful air pollutants already damaging public health," explains Shaolei Ren, a study author.

The research team recommends that tech companies report air pollution from their electricity use and generators. They also call for proper compensation for communities suffering the worst health effects from this pollution.

Notably, AI-related air pollution harms certain low-income neighborhoods more severely, partly because they often sit closer to power sources. Furthermore, pollution spreads across state boundaries. "Data centers pay local taxes," Ren notes, "but health impacts reach nationwide. Other affected areas receive no compensation." For example, pollution from Virginia data centers spreads into seven neighboring regions.

As tech companies compete to launch new AI services, dangerous air pollutants — especially tiny particles entering lungs — are expected to rise sharply. By 2030, health damage from AI pollution could match that of all vehicles in California.

"AI's growth hugely increases demand for data centers and energy, making it the fastest-growing energy user across all industries," Ren states. Training just one major AI model creates pollution equal to 10,000 car trips between Los Angeles and New York.

"If your relatives have asthma or heart conditions, this pollution may harm them today. This serious health problem cannot wait," Ren warns.

In 2017, Rao won the first place in the Discovery Education 3M Young Scientist Challenge. This brought her wide attention. She decided to use her talents to solve real problems. After learning about unsafe drinking water in Flint, Michigan, she created Tethys. This device tests water for dangerous lead and sends results to a phone. Later, she designed Kindly, an app that uses computer smarts to find hurtful online messages early. She also built Epione, a tool to help doctors spot signs of drug addiction.

Rao is also a writer. Her first book, Baby Brother Wonders, came out in 2015 when she was just ten. In 2020, she published A Young Person's Guide to Science and Technology. That same year, TIME Magazine chose her as the first ever Kid of the Year, featuring her on its cover. She also received other important awards including a place on Forbes Magazine's 30 Under 30 list.

Outside of science, Rao enjoys Indian classical dance, singing and playing the piano. She has shared her ideas at TEDx events and appeared in a Marvel television show. Her story teaches us that young people can make a big difference in the world.

Zhong Nanshan, is considered one of the most outstanding doctors in China, has made numerous contributions to our country. He is a courageous and kind figure(love) by many people.

This devoted and patient physician was born in Nanjing, Jiangsu Province in October,1936. He(commit) himself to caring for and treating patients ever since he graduated from Peking Medical School. In 2020, Wuhan encountered COVID-19. impressed us most was that this 84-year old man rushed to the front line without (hesitate). Dangerous as it was, he and his team risked (they) lives, working day and night to search for the treatment for the disease. Despite many (fail), they never acknowledged defeat. Finally, the team succeeded in the fight against the disease,(save) numerous lives. With their efforts, the spread was control and our country got back on its feet.

Doctor Zhong has won great respect    admiration from all the people and has been awarded the Medal of the Republic.

I moved to a/an5 near home. Every Sunday, with all schoolwork finished, I went home and helped Dad. To my sadness, he6 everything I did. "It's not you." Mom explained to me. "What7 him makes him feel bad about himself. His anger was masking (掩饰) his frustration (挫败)." I was so8 to hear that. Now I saw his pain went beyond the bodily pain, and that made me try harder to9 him.

One day we were watching a football game. I said, "I'll10you $2 million that Dallas wins." Dad looked at me. "You don't have $2 million." he11. After that, every time we watched the game, we made the same bets. Dad laughed more easily and accepted my help more12. Our relationship was13.

Find shelter immediately

If you find yourself caught in a lightning storm, never stand under a tree, and avoid being close to power lines as they're both excellent conductors (导体) of electricity and could potentially cause death, if not serious injury. . It's the key to minimizing danger.

Watch out for dangers

Windows provide a direct path for the lightning to travel. Keep windows closed, stay away from them and try to stay within inner rooms of the structure. Using a landline phone is the main cause of lightning-related injuries. Lightning can travel into the home from through any material that conducts electricity. This includes landlines, electrical wiring, and plumbing.

Being near water is extremely dangerous during a lightning storm, so move away from the body of water. If you are fishing, swimming or on a boat, get out of the water immediately and hurry back to the bank.

Stay inside

Stay inside at least 30 minutes after the last strike. Don't go out just because the rain is starting to let up. There is still a significant risk of lightning strikes from a departing storm. .

Lightning is dangerous but you can minimize your risk. The advice is simple: increase the awareness of avoiding danger and master proper knowledge to protect yourself from a thunderstorm.

A. Get away from the water

B. Prepare enough water

C. Go to hospital quickly

D. Don't touch anything metal or electrical

E. Find shelter near or under a stony shelter

F. Wait for news that the danger has passed

G. Fortunately, most lightning-related deaths are preventable

This phenomenon can be seen in most colleges. For example, at Dartmouth there was a section of the main library that was open twenty-four hours a day and the students I used to see in there late at night crowded in groups, drinking coffee, were definitely pseudo-working.

By placing themselves in distracting environments and insisting on working long hours, these students are damaging their brain's ability to think clearly and efficiently to accomplish the task at hand. In the end they get half the results with twice the effort.

The bigger problem here is that most students don't even realize that they're pseudo-working. To them pseudo-working is work — it's how they've always done it, and it's how all of their friends do it. It never crosses their mind that there might be a better way. Straight-A students, on the other hand, know all about pseudo-working. They fear it, and for good reason it not only wastes time, but it's also mentally tiring.

In fact, the most important skill in becoming a better student is the ability to get work done quickly and with a minimum of wasted effort. Some cognitive science research concludes that about 50 minutes is the optimal learning period to maximize the material learned per time unit.

So how can students manage to study efficiently? One key factor is captured in the following simple formula: work accomplished = time spent×intensity of focus. Pseudo-working features a very low intensity of focus. Therefore, to accomplish something by pseudo-working, you need to spend a lot of time. The straight-A approach, on the other hand, maximizes intensity in order to minimize time.

The outbreak of World War II led to a national shortage of chemists and scientists. In spite of the fact that she was still a student and a woman, she was offered a job as a chemical analyst due to her talents, producing explosives (爆炸物) for the wartime effort. She put her degree on hold and moved to Ohio, taking on the dangerous job of analyzing unstable chemicals to produce weapons. 

After the war ended there was a fall in demand for explosives, so she made a move to the field of aeronautics, moving to California to work for NAA (North American Aviation). The only woman out of 900 engineers, she was soon promoted to a role which involved calculating the performance of rocket propellants (推进剂) and designing special fuels to work with different engines. However, never having returned to complete her degree, she was not afforded the rank or higher pay of an engineer, even though she had all the skills and knowledge of one. 

Her experience with propellants meant that when NAA was tasked to find a fuel capable of lifting the redesigned Redstone missiles into space, Morgan was appointed technical lead on the project. National pride was on the line, so Morgan set about investigating fuels. After countless trials, she finally designed her own mixture, which was named Hydyne. 

Hydyne tested well with the Redstone missiles and subsequently other aircraft (飞行器) , such as Jupiter-C rockets, proving to be a quick solution to getting to space without a total rocket redesign. The fuel made the first successful US satellite launch possible, even if Morgan silently slipped away from her success, retiring to focus on her family and leaving her chemistry career behind.

The blind box phenomenon isn't limited to collectibles. Businesses across sectors can incorporate this trend to increase customer engagement, attract a wider audience, and enhance the shopping experience. Here are a few ideas for how different types of businesses can incorporate blind box concepts.

Create mystery product boxes.

Introduce a line of mystery boxes for your products. For example, a beauty brand could create blind boxes with a mix of skincare or makeup products. Each box could include items of varying values, creating an element of surprise for customers.

Create exclusive (独有的) blind box series that feature one-of-a-kind items or unique packaging, which can increase demand and bring in regular customers. Offering these boxes on a seasonal or limited-time basis also adds an element of urgency, motivating customers to act quickly.

Incorporate blind boxes in loyalty programs.

For businesses with loyalty programs, offering blind boxes as part of a rewards program can drive engagement. This would give them a unique stimulation to continue buying and interacting with your brand.

Adopting the blind box model can help businesses tap into the excitement and mystery that drives this trend, while also providing a fun and memorable experience for customers. By adding elements of exclusivity and variety, brands can boost sales and customer loyalty, turning each purchase into an engaging experience.

A. Consider rarity an artistic focus.

B. Launch limited-edition blind boxes.

C. This trend started in Japan and quickly spread worldwide.

D. And a fashion shop might offer mystery gift packs.

E. Regular customers could exchange points for mystery boxes.

F. There are countless social media groups discussing the blind boxes.

G. It has also become a business model for industries ranging from fashion to beauty.

The Coller Dolittle Challenge financed by Jeremy Coller, a vegan and animal lover, is unashamedly modelled on the Turing test (图灵测试). That 20th-century test promotes efforts to design a machine capable of imitating human conversation, and became a touchstone in the evolution of AI. It also became a focus for concerns about machines tricking, even taking over, humans. The ability to commune with other species is likely to raise similar, unsettling questions as research progresses. If we were able to decode animal chatter, should this knowledge change how we treat them, whether as pets, labour or food? The prize presents a moral challenge and it forces us to reconsider our relationships with other species.

Philosopher Jonathan Birch, also a judge of the Jeremy Coller Centre, stressed that the Challenge is looking beyond the interspecies communication we have with pets, or that a farmer has with a sheepdog. Those relationships involve signalling and behavioural responses, Birch explains, "but that's not telling us how animals communicate with each other... this prize is about understanding it so well that we can start to join the conversation."

While Coller hopes his charity will reshape our attitude to animals, the truth is that even groundbreaking research has largely failed to move the dialon their welfare. Recent work on cephalopod's (头足类动物) intelligence has not stopped plans to farm the creatures. We might one day be able to understand what animals are saying — but there is no guarantee we will listen.

But some worry that so much messaging leads to less communication. For instance, when hanging out with friends, we'd be texting secretively at the same time, pretending to maintain eye contact but mentally somewhere else.

New technologies often upset the way we relate to one another, of course. But such division caused by texting has a strong echo in the arguments we had over telephone a hundred years ago. The small device gave us a new way to contact one another and quickly promote new forms of socializing. Callers arranged regular "visiting" calls, dialing remote family to catch up on news.

Soon, though, social critics thought it would be so easy to talk that we'd never leave each other alone. Others worried that the telephone sped up life, demanding instant reactions. The use of the telephone gave little room for reflection. It produced a craziness in the ordinary concerns of life which didn't make for domestic happiness. "We shall soon be nothing but transparent piles of jelly (果冻) to each other," a London writer moaned in 1897.

However, nowadays the telephone call seems like a throwback to a gentler era. When Jenna Birch, a communication professor at the University of Iowa, started dating a man who insisted on calling her on the phone, she found it warm and delightful. So she doesn't think the shift to texting has degraded our interactions. According to her study, teenagers who text the most are also those who spend the most time face to face with friends. Communication, it seems, brings more communication, and — as she argues — just because talk happens in text doesn't mean it's not meaningful.

Michéle Martin of Carleton University, thinks we're living through a replay of the telephone, where the things that made it valuable — instant communications — are the same that made it annoying. "People believe they are liberated because they can bring the mobile phone everywhere," Martin says. "But at the same time, they are slaves to it."

Norton built his own career in a different field, becoming one of his generation's most respected actors. When Norton first became famous, he concluded that he wasn't interested in ordinary celebrity ambassador work. "I am not interested in being some weak sauce kind of spokesperson," he says. "It's not that I don't believe those things are important, but that held no nourishment for me."

What does nourish Norton is his work with a Kenya-based organization called the Maasai Wilderness Conservation Trust which helps the Maasai people to make a living from their land through innovative means. One project that Norton is particularly proud of channels profits from the sale of carbon offsets (碳补偿) to local Maasai communities who use that money to support health, education, and conservation initiatives.

One challenge that concerns Norton would be familiar to his father and grandfather: raising funds. This led Norton to a realization. "We can't have the conservation movement depend only on donor-funded charity," he says, "It not only can't scale; it's fundamentally unstable."

A new model is needed. Norton and his partners argue that tourist dollars being spent in fragile places ought to remain in-country — or better yet, in-community. Norton and his team have started a company called Conservation Equity that will invest in tourism in critical places and will reinvest its profits locally, instead of paying distant shareholders.

Norton is optimistic about the model's prospects, "I think what we are doing has no previous example to follow. The needs of people are not going to take a lower priority to the spiritual value of nature. If protecting and restoring nature can't produce a stronger and more reliable economy, the effort will fail."

How often do we get(stick) in traffic jams? How often do we arrive at work or school,(stress) out, tired and angry? For many, the answer is every day. But personal(angry) and stress are nothing(compare) to the real costs socially.

Can a sixth extinction(avoid)? Experts say it is not yet too late if we take action now. We need to take steps to save endangered species, including setting up special areas plants and animals can be protected. We need to change how we work and travel by using cleaner,(natural) sources of energy. If we want to survive, we need to stop(destroy) the planet.

The third mass extinction was known as the "Great Dying", killed 90% to 96% of all species. And the fifth event, which(occur) 66 million years ago, caused the death of the dinosaurs. The reasons for extinctions are varied, including volcanic eruptions, asteroids(hit) the earth from space and global warming. Many scientists say we are entering the sixth mass extinction. This time, human activity will be(blame). Although it is not unusual for species to die naturally, the rate at which this is now happening is cause for concern.
