1 . Artificial intelligence (AI) is showing promise in earthquake prediction, challenging the long-held belief that it is impossible. Researchers at the University of Texas, Austin, have developed an AI algorithm(算法) that correctly predicted 70% of earthquakes a week in advance during a trial in China and provided accurate strength calculations for the predicted earthquakes.
The research team believes their method succeeded because they stuck with a relatively simple machine learning approach. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI provided its prediction by listening for signs of incoming earthquakes within the background rumblings(隆隆声) in the Earth.
This work is clearly a milestone in research for AI-driven earthquake prediction. “You don’t see earthquakes coming,” explains Alexandros Savvaidis, a senior research scientist who leads the Texas Seismological Network Program (TexNet). “It’s a matter of milliseconds, and the only thing you can control is how prepared you are. Even with the 70% accuracy, that’s a huge result and could help minimize economic and human losses and has the potential to remarkably improve earthquake preparation worldwide.”
While it is unknown whether the same approach will work at other locations, the researchers are confident that their AI algorithm could produce more accurate predictions if used in areas with reliable earthquake tracking networks. The next step is to test artificial intelligence in Texas, since UT’s Bureau TexNet hastions and over six years worth of continuous records, making it an ideal location 300 earthquake sta for these purposes.
Eventually, the authors hope to combine the system with physics-based models. This strategy could prove especially important where data is poor or lacking. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.

2 . As my husband and I drove down a country road, we passed a fire station with a sign that read. “Are you ready for the next storm?” Our area had just been in the path of Hurricane Irma, causing downed trees and power off.
We have had our share of storms in the past — a snowstorm and other heavy snows that knocked down trees, sometimes up to a week at a time. Those days weren’t fun, but we learned so much from those early storms. It made later storms easier to bear.
We’re ready for the next storm, but we wouldn’t have learned to do all those things if we hadn’t faced a storm in the past. The same is true spiritually. Those little storms in our lives are never fun, but they prepare us for the big trials coming to us.
Are you ready for the next storm?

3 . Eradajere Oleita thinks she may have a partial solution to two of her country’s problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than throw your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.
Chip waters drop off their empty bags from Doritos. Lays. and other favorites at two locations in Detroit:a print shop and a clothing store. where Oleita and her volunteer helpers collect them. After they clean the chip bags in soapy hot water, they slice them open, lay them flat, and iron them together. They use padding (衬垫) and liners (衬里) from old coats to line the insides.
It takes about four hours to sew a sleeping bag and each takes around 150 to 300 chip bags depending on whether they’re single-serve or family size. The result is a sleeping bag that is “waterproof lightweight and easy to carry around”. Oleita told the Detroit News.
Since its start in 2020, the Chip Bag Project has collected more than 800,000 chip bags and, as of last December, created 110 sleeping bags. Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita — whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life —and her fellow volunteers. “We are devoted to making an impact not only socially, but environmentally,”she says.
And, of course, there’s the symbolism of rescuing bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental problem and poverty often go hand in hand. As Oleita told hourdetroit.com, “I think it’s time to show connections between all of these issues.”

4 . Two and a half months before the 2024 Atlantic hurricane season officially begins, and almost six months before it enters its peak (高峰), weathermen are already predicting (预测) that it could be particularly active.
Officially, hurricane season begins from June 1 and runs through November. One reason is that sea surface temperatures in the tropical (热带的) Atlantic are already at record highs.
Meanwhile, another significant potential factor in this year’s hurricane season is taking shape thousands of miles away in the Pacific. Over periods ranging from three to seven years, the waters of the central and eastern tropical Pacific Ocean warm and cool in turn as a result of a repeating climate pattern called the El Niño-Southern Oscillation (ENSO). El Niño makes Atlantic hurricanes less likely to form but La Niña does.
During the 2023 season, ENSO was in an El Niño period. However, by the time the 2024 season starts, it will have changed into a “neutral(中立)” period, but that by the peak months, it is likely to have changed fully into a La Niña.
“How quickly that change occurs can affect everything as well,” says DaSilva, a lead hurricane weatherman. “There’s a lag time. So, while we expect the change to occur in mid-summer, it may not be until late summer or fall where we really see those effects across the Atlantic basin.” As a result, he says, this year’s hurricane season could remain particularly active deep into November.
Of course, no report can predict when individual storms will come or the paths they will take, but DaSilva warns that those who live in areas likely to suffer hurricanes, especially around the Caribbean and Gulf of Mexico, should prepare. “If a tropical storm system comes into this area, it could rapidly strengthen, potentially close to land,” he also warns. “And that’s why people need to be careful and have their hurricane plans ready. Because any system with these kinds of conditions can explode very quickly. That’s what we’re concerned about.”

8 . The Forest Eye project aims to create the largest living forest feature in England by growing 5,000 alder, beech and maple trees into the shape of a child’s eye. The trees are being planted in Dalby Forest, North Yorkshire, with the help of local young people. The trees will form an eye 300 meters wide that will be visible from the sky in about six years, when they have grown.
The project hopes to focus on the importance of young people’s ideas for creating a health y natural environment. It was designed by a company called Sand in Your Eye and has been created by Forestry England, an organization that protects forests and woodlands.
Josephine Lavelle, director at Forestry England, says, “Having the gaze of a child growing in the heart of this beautiful and ever-changing forest is a powerful symbol of how we need to listen and respond to the needs and vision of future generations.”
The project also aims to highlight the important role that forests play in fighting climate change. As well as providing a home for wildlife, trees absorb carbon dioxide from the atmosphere and create oxygen that humans need to breathe. When the trees have grown, they will provide a place for lots of wild animals, like bats, birds and small mammals to live. The Forest Eye will also create a space for people to explore and connect with nature.
Jamie Wardley, artistic director at Sand in Your Eye, has plenty of experience creating pieces of “land art”. These are huge drawings and sculptures made from grass, ice and sand, including a 60-meter portrait of Swedish climate-change campaigner Greta Thunberg on a school field in Yorkshire. He says, “The trees are my paint.” “Our work is about prompting people to think deeply and respond emotionally to some of the biggest issues facing us, including the climate crisis.” Wardley also plans to develop the Forest Eye into an even bigger project. “It is our ambition to create the whole face of a young girl at the same scale, measuring 2,000 meters across. Those trees that are planted in the Forest Eye are the very beginning of this,” he says.

9 . In many ways, life has become far more comfortable and convenient in the past few decades.
Air Pollution
The main cause of air pollution is the burning of fossil fuels by vehicles and power plants. Other human activities, such as construction and the burning of waste, also contribute to air pollution. The effects on our health can be very serious.
You can easily contribute to reducing air pollution by only using a car to make journeys when it’s absolutely necessary.
Global Warming
Global warming is the increase in the temperature of the Earth’s near-surface air and oceans. It’s caused by the build-up of carbon dioxide and other pollutants in the atmosphere. These trap the Sun’s heat and warm up the planet.
Global warming has already caused a wide range of problems.
Overflowing Landfills
Landfills are used for waste disposal (处理) in many countries around the world. However, these landfills are now nearing their limit. When this happens, the chances of dangerous chemicals in the waste entering our water supply increase.
The amount of waste in landfills in China has risen sharply over the last ten years.
| A．If it isn’t, try using public transport instead. |
| B．Sea levels are rising due to the melting of polar ice sheets. |
| C．However, this has come at a huge cost to the environment. |
| D．This resulted in the flooding of the River Po near Turin in Italy. |
| E．For instance, that in Hong Kong is likely to reduce within a few years. |
| F．Thus, the government is now trying to find alternative waste disposal methods. |
| G．Apart from the three Rs, some experts have called for the fourth R—Responsibility. |
10 . Topher White spends so much time walking in the forest and thinking about how quickly we’re losing it. The engineer is determined to stop global deforestation. Founder of the San Francisco-based non-profit Rainforest Connection, White has developed a small but clever strategy: using old cell phones to listen for the sound of destruction.
Forests are disappearing worldwide, and fast：an area about half the size of England is lost each year. The Amazon has lost close to one-fifth of its rainforest cover in the last four decades. Forest loss not only harms wildlife, including many species that live nowhere else, but it’s also a big contributor to the greenhouse gas emission(排放)that cause climate change.
”I didn’t know any of this when I started,“ says White, who began his journey in 2011, when he traveled to Indonesian Borneo to help decreasing gibbons(长臂猿).
Between 50 and 90 percent of the logging that happens in the world’s rainforests is illegal, according to White, yet detecting chainsaws(电锯)and other sounds related to that activity can be tough, because the air is already filled with the loud unpleasant mixture of sounds from nature. So he has developed a system in which he installs a cell phone that stays charged by solar cells, attaches an extra microphone, and listens. From there, the device can detect the sounds of chainsaws nearly a mile away.
Because it’s unfeasible to have people listening to the devices all the time, he added some “old-school data analysis”, so that the cell phone’s computers can distinguish a chainsaw’s sound from others in the forest. This way, his device can automatically detect logging activity and send a text alert to authorities who can determine if it’s illegal and then stop it.
White notes that he’s not alone in the fight: Many people and organizations are working tirelessly to stop forests from disappearing. For instance, local groups are particularly active in forest conservation efforts, White says.
So far, his monitoring devices have been used in Cameroon, Ecuador, Peru, and Brazil and will soon be used in Bolivia. It’s not just about listening for logging. The same technology that can pick out the buzz of a chainsaw can pick out the sounds of specific birds, which is why Whtie sees the forest recordings as a potential science tool. He’s urging biologists and ecologists to use his monitoring system anywhere, whether it’s a remote forest or a park in London. “The more we learn about these places,” he says, “the easier it’ll be to protect them.”
