1 . The opening of California’s commercial crab season, which normally starts in November, is delayed once again to protect whales searching for their prey (猎物) along the coast.
California has been affected by a marine heat wave since May. The Blob, as this mass of warm water has become known, is squeezing cooler water preferred by whales and their prey close to shore, where fishermen set their traps. This crowding can lead to tangle (缠结) between whales and fishing equipment, endangering the animals’ lives and requiring rescue missions.
In a new study, scientists say they can now use global temperature models, commonly used in climate science, to predict up to a year in advance when hot ocean temperatures raise the risk of tangles between whales and fishing equipment.The tool analyzed in the new study, called the Habitat Compression Index, works by feeding sea-surface temperature measurements into an equation (方程式) that estimates the likelihood of whale habitat shrinking closer to shore.Regulators and fishermen agree that the new forecasting research could help them walk the tightrope between protecting whales and protecting local livelihoods (生计).
Mr Ogg, a commercial fishing boat captain, describes himself as a conservationist who doesn’t want to see whales harmed.“Fishermen have a big motivation to protect the natural environment,” he said, “because that’s where they make their living.” Previously, the challenge was adapting to changing conditions and fishing regulations on short notice, especially for smaller business owners and their crews.“One of the biggest problems we had was the unpredictability,” Mr Ogg said, “We were living from week to week then.”
Though scientists have shown the Habitat Compression Index can now forecast months in advance, state officials would probably wait to see conditions in real time before making decisions about the crab fishery, said Ryan Bartling, an environmental scientist at the California Department of Fish and Wildlife.

3 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.
In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.
Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.
Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.
This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

4 . Inside a fishbowl, the goldfish — a species of carp native to East Asia, bred for aesthetic delight and traditionally believed to bring good fortune — is among the easiest of pets to keep. But released into the wild, the seemingly humble goldfish, freed from glass boundaries, can grow to large proportions. They can even kill off native marine wildlife and help destroy fragile and economically valuable ecosystems.
“They can eat anything and everything,” said Christine Boston, an aquatic research biologist with Fisheries and Oceans Canada. Over the past several years, Ms. Boston and her colleagues have been tracking invasive goldfish in Hamilton Harbour, which is on the western tip of Lake Ontario (安大略湖), about 35 miles southwest of Toronto.
Their study, published last month in the Journal of Great Lakes Research, could help pinpoint goldfish populations for culling, said Ms. Boston, who is the lead author. “We found out where they are before they start spawning (产卵),” she said. “That’s a good opportunity to get rid of them.”
The fast-growing female goldfish, Ms. Boston noted, can also reproduce several times in one season. “They have the resources,” she added, “and they can take advantage of them.” Their football-shaped bodies can swell to a size that makes them too large a meal for predators (捕食者) — up to about 16 inches long. The feral goldfish are also destructive, uprooting and consuming plants that are home to native species.
Nicholas Mandrak, a professor of biological sciences at the University of Toronto Scarborough, studies in the “dramatically increase” of the wild population in the past two decades. Their spawning explosion, he said, resulted partly from people in densely-populated areas releasing pets in urban ponds. He added, environmental managers tend to forget the goldfish. “They just assume, ‘It’s been there for 150 years — there’s nothing we can do about it.’”
The problem is not unique to Canada. In Australia, a handful of unwanted pet goldfish and their offspring took over a river in the country’s southwest. And the discovery of football-size creatures in a lake in 2021 even led British officials to beg their citizens: “Please don’t release your pet goldfish into ponds and lakes!”
People wrongly believe that because goldfish are “small and cute” they won’t pose a problem when released into the wild, said Anthony Ricciardi, a professor of invasion ecology at McGill University in Montreal.
Goldfish, he added, are just a small part of a vast invasion of non-native species whose outcomes can be unpredictable, and in some cases, are worsened by climate change.
“Under human influence, beasts are moving faster farther in greater numbers, reaching parts of the planet they could never reach before,” he said. “We’re talking about the redistribution of life on Earth.”

| C．They will grow well over 16 inches. | D．They only invade Lake Ontario. |
| A．Killing | B．Controlling | C．Catching | D．Observing |
| A．Citizens wrongly set free the fish. | B．Climate change has a negative impact. |

5 . Cell phones, tablets, laptops, smart-watches: the modern world is packed with a lot of devices that bring us connectivity, entertainment and information. Our hunger for the latest models leads to the “throwaway” culture, which means consumers often throw away old devices as soon as new ones come to the market, a habit that can have a significant effect on waste streams and the environment.
With concerns about e-waste growing, some companies are now turning to chemistry to develop solutions to recycle items like old cell phones, extracting value at the same time. One such example is the work being carried out by Mint Innovation, a clean tech firm based in Auckland, New Zealand. “We’ve developed a biological process for recovering valuable metals from electronic waste,” said Ollie Crush, the company’s chief scientific officer.
Crush explained that Mint Innovation’s system included grinding(磨碎)waste up into a powder. “The reason why we must do this is that we need to make sure that we’re exposing all the metal contained within to a chemical filtering(过滤)process,” he added.
When it comes to recovering a valuable material like gold, the technique used by Mint Innovation has a number of steps. According to a video, chemicals dissolve (溶解) the powdered waste into a solution, with any materials that haven’t dissolved filtered out. Microbes are then added to the mix. Gold atoms catch on to them in a process called “selective biosorption”. Next, the microbes coated gold are filtered, producing a paste which is then turned into a solid, “recycled” gold.
“Nearly 50% of the value of e-waste comes from the gold,” Cameron Weber, a senior lecturer at Chemical Sciences, said. “In fact, there’s actually more gold in e-waste as a concentration than there is in gold that’s been mined, which shows you the value of being able to take your e-waste and recycle and reuse some of the elements that are found in it,” he added.
Looking ahead, Crush, explained the process could potentially have a number of interesting applications. “The future for Mint Innovation is to prove that our technology works with a number of different materials,” he said. “So, we’ll just keep trying to see where our microbial process makes more sense.”

7 . Mobile Bay in Alabama is home to a strange and unique occurrence. During the summer months, hundreds of fish and crustaceans (甲壳纲动物) from the deep waters of the bay move to the shallow waters. The free seafood is so plentiful and easy to catch with nets or bare hands that locals gather to fill their buckets with it. This natural phenomenon has existed for centuries.
Sarah Van Winkle, a student at the Alabama School of Math & Science, is no stranger to the scene. Growing up there, the rich plants and animals never stop to amaze her.
As the world’s oceans face numerous issues such as pollution, overfishing, and habitat destruction, she intended to figure out whether Mobile Bay was experiencing similar environmental threats in her most recent science project. Sarah studied the environment of Mobile Bay and she even extended the range of the research to the Mobile Tensaw-Delta, and the canals of a living district in Fairhope, Alabama. She analyzed key nutrient and metal levels in the ocean ecosystem.
Through the project, Sarah found that turbidity, an important indicator of water quality, increased sharply. This result showed, clearly that the area is filled with tiny pieces of matter, making the water there quite opaque.
For the project. Sarah was chosen as one of this year’s 24 Society for Science & the Public Community Innovation Award winners. “To me, this honor symbolizes that the ten months of late night readings, weekend field trips, and after-school sessions in the laboratory have truly come to fruition and impacted lives,” Sarah noted.
“Our local ocean ecosystem is in danger of chemical pollution from a variety of sources,” Sarah explained in an interview. “The bay plays a vital role in our community and every local should value what the bay offers. It’s our responsibility to work together to preserve it.”
1. What’s the unusual scene in Mobile Bay in summer months?| A．The water’s becoming shallow and clear. | B．The decline of the natural environment. |
| C．The flood of seafood into shallow waters. | D．The locals’ growing interest in fishing with buckets. |
| A．Fresh. | B．Cloudy. | C．Clear. | D．Shallow. |
| A．Hard work pays off. | B．Time waits for no man. |
| C．Practice makes perfect. | D．Failure is the mother of success. |
| A．The focus of her future work. | B．Her concern for the local people. |
| C．The complexity of the local ocean system. | D．Her expectation of protecting the bay. |
8 . In late spring and early summer each year, tens of millions of butterflies come out of their chrysalises (蚕蛹) in the butterfly valley in southwest China’s Yunnan province. For butterfly expert Yang Zhenwen, it is the busiest time of the year, but he greets it with great enthusiasm.
Before the break of dawn, Yang has already arrived at the observation point, busily tending to the needs of the awakening butterflies. “Due to warmer temperatures, the ‘butterfly explosion’ this year occurred slightly earlier than usual, and the size of the butterflies is larger than that in previous years,” said 46-year-old Yang, curator (馆长) of the butterfly valley museum. “We expect that there will be about 80 million to 100 million butterflies in the valley during this year’s ‘butterfly explosion’. That seems so crazy,” said Yang. According to Yang, in the valley, more than 320 butterfly species have been identified in specimens or photographs, including the rarest, most primitive, largest and smallest butterflies in China.
Besides Yang, many local villages have also assumed the role of butterfly guardians. However, the journey toward achieving human-butterfly harmony was far from easy. Some two decades ago, the villagers had little awareness of butterfly protection, believing wrongly that butterflies could endanger their food crops. They viewed them as pests that should be removed.
In 1998, Yang began his journey at the agricultural science station in Ma’an’di Township, the very place where the butterfly valley lies. “It was there that I got into a frequent dilemma— the local villagers, seeking to protect their crops, would often turn to pesticides to kill the butterflies,” he said. “However, my sincere love for these creatures forced me to prevent them from harming the delicate insects.”
Now, the development of ecotourism relying on butterfly resources has successfully changed the once extremely poor township. More villagers have started reproducing butterflies. He describes the butterfly valley as a “dream-making machine”, which extends the “butterfly dream” of harmonious coexistence between humans and nature.
1. What made Yang’s aim to reach human-butterfly harmony hard in the beginning?| A．Warm temperatures in local villages. | B．The number and size of the butterflies. |
| C．Improper location of the butterfly valley. | D．Lack of awareness of butterfly protection. |
| A．A choice difficult to make. | B．A fact easy to understand. |
| C．A duty hard to carry out. | D．A situation smooth to deal with. |
| A．Honest and professional. | B．Humorous and creative. |
| C．Hard-working and strong-willed. | D．Generous and easy-going. |
| A．Changing the Poor State of a Town | B．Volunteering as a Butterfly Guardian |
| C．Helping Butterflies Spread Their Wings | D．Developing a Relationship with the Locals |
9 . Working at an investment bank in New York City in the mid-2010s. Anna Sacks was living the life—just not the life she wanted. Sure, she was happy. But she wanted to do something that felt important and was fulfilling on a deeper level.
Sacks packed up her life and moved to Connecticut for three months to participate in Adamah, a Jewish farming program that focuses on sustainable living and growing sustainable food. The Adamah program opened Sacks’s eyes to the damage consumer culture is doing on a local, national, and global level, and the need to find solutions. From then on, she began what she calls “trash (垃圾) walking.”
While walking around her neighborhood, Sacks, 31, picked through rubbish to look for reusable items. Soon, her trash walks expanded to include company rubbish along with residential trash. Surprisingly, she discovered a wide range of really great stuff—like clothing, dinnerware, and food—all of which she documents on Instagram and TikTok.
Under the name The Trash Walker, Sacks quickly gained popularity for her educational, funny, and surprising videos that highlight the problems with consumerism and share information about how to live a more sustainable life. “The root issue is overproduction, which leads to overconsumption, which leads to a large amount of waste,” she says. Sacks’s videos have gone viral many times, causing shockwaves through the industries she calls out.
Trash walking has given Sacks a nearly endless supply and she shares much of her “treasure” with others. She tries giving them informally to family, friends, or individuals she knows may need a specific item. Then she takes the remaining items to free stores so other New Yorkers can benefit from her treasure-hunting.
Sacks’s main focus is simply getting people to pay attention to how many unnecessary things they buy and then throw away. “Once you become aware of the way you consume, you can see ways you improve,” she says.
1. What inspired Sacks to begin her “trash walking”?| A．Her desire to live a richer life. | B．The great need for household stuff. |
| C．Her involvement in a project. | D．The wish to be an Internet star. |
| A．Funny stories. | B．Views on consumption. |
| C．Educational courses. | D．Solutions to problems. |
| A．She donates all to the charity. | B．She keeps most for her family. |
| C．She gives away much to others. | D．She sells some to individuals. |
| A．Trash Walker: Find Treasure in Trash. |
| B．Trash Walking: A Tough Journey. |
| C．Trash Walker: Live in the Moment. |
| D．Trash Walking: A New Career. |
10 . This summer we witnessed interview teams at the North Pole wearing short sleeve shirts due to the warm weather. A study published on Aug 29 revealed more concerning issues in the supposedly coldest area of the world. Zombie ice from a massive Greenland ice sheet was confirmed to be melting, which would eventually raise global sea levels by at least 10 inches (27 centimeters) on its own, reported Associated Press (AP).
Zombie ice is the kind of ice that is still attached to thicker areas of ice but is no longer getting fed by larger glaciers. Since glaciers are getting less snow to make up for the amount of ice melted, once the zombie ice is melted, it cannot be re-formed.
Scientists decided to look at the balance of the ice. In perfect equilibrium (平衡), snow in the mountains of Greenland flows down and thickens the sides of glaciers, balancing out what’s melting on the edges, according to AP. But in the last few decades, there is less refill and more melting, creating an imbalance.
Study co-author William Colgan at the Geological Survey of Denmark and Greenland told AP that 3.3 percent of Greenland’s total ice volume will melt eventually. “Starying would be a good phrase” for what’s happening to the ice, Colgan added.
With a great number of natural resources buried under the earth, areas of melted ice revealed treasures that attracted the world’s richest men. According to CNN, in early August, there was a “treasure hunt” in Greenland. Billionaires, including Bill Gates and others, financially backed KoBold Metals, a US-based mineral exploration company, to explore the rare metals under the glaciers in Greenland. The company told CNN that since there were enough minerals to power hundreds of millions of electric vehicles, the critical resource is capable of powering the green energy transition.
While investors are taking advantage of global warming, experts express their concerns that the mineral exploration is likely to worsen the local environment, running out of the world’s resources at a faster rate.
