1 . In a study from Washington State University, researchers have uncovered a significant correlation between the closeness of older adults to green and blue spaces and their mental and physical well-being. The study offers convincing evidence that even small increases in access to nature can remarkably improve the health outcomes of older adults.
A mere 10% increase in forest space within a person’s living environment is linked to a noticeable decrease in serious psychological conditions. This type of suffering includes mental health challenges that need treatment and block normal social, occupational, or educational functioning. Similarly, the new study proves that enhancing green spaces, water bodies, or trail lengths by 10% appears to lower the likelihood of older individuals reporting their overall health as poor.
The researchers analyzed health survey data from over 42,000 people aged 65 and above living in urban areas of Washington state, spanning (跨越) the years 2011 to 2019. The experts related the health outcomes of these individuals to various measures quantifying their access to nature within their living areas.
Initially presented at the American Academy of Neurology Annual Meeting in April 2023, the research focused only on the link between psychological depression and closeness to natural spaces. The final study expanded to include additional metrics (指标) such as green space percentage and trail length, also taking into account demographic variables (人口统计变量) like race and education.
“Our findings suggest that abatement of our urban green and blue spaces due to rapid urbanization may not just have an environmental impact but could have a public health impact as well,” said Adithya Vegaraju, first author of the study.
Vegaraju said this research is among the first in the U. S. to specifically investigate the relationship between access to nature and health in the older population.

2 . If you’ve ever seen elephant seals (象海豹) lying on a beach, you might think that they’re always. sleeping. But in fact, they spend about seven months of the year in the ocean. So how do they sleep while they’re in the ocean?
Even though elephant seals are large animals, they have to be careful in the ocean. Near the surface, some dangerous animals like sharks might attack(攻击)them. So elephant seals spend most of their time diving (下潜) deep underwater, looking for food.
To find out how they sleep in the deep, a scientist named Jessica Kendall-Bar created a special cap. She and her team put the caps on thirteen female young elephant seals. The caps recorded the elephant seals brain activities. They also collected information on the elephant seals’ heart rates (心率), how their bodies were moving, and how deep they were.
The scientists learned that elephant seals sometimes sleep for a short time while they are diving. They only sleep for about 10 minutes at a time. As they begin to sleep, the elephant seals can control their bodies. But when they are deeply asleep, they simply begin to fall, spinning (快速旋转) in a circle “like a falling leaf”. The elephant seals wake up in time to go up for more air. In shallower (较浅的) areas, the elephant seals sometimes wake upon the seafloor.
Using the information they collected from the cap-wearing elephant seals, the scientists created a computer program to study older records of elephant seal trips. The scientists found that elephant seals only sleep for about two hours a day when they’re in the ocean. That means that the rest on land is very important for them. Back on land, they sleep for about 10. 8 hours a day.
The scientists hope that their work will help to protect the places where elephant seals sleep when. they’re on land.

3 . Most people suffer from what is known as “Just-me-ism”. What is that? Well, say you leave the tap running while you brush your teeth, leave a light on when you go out or you drop a piece of litter (垃圾) and can’t be bothered to pick it up. You know that all those things are wrong. But so what? “What difference can it possibly make?” you say to yourself. There are millions of people in the world and I’m just me. How can it matter if I leave one little tap running, one little light on or leave a little piece of litter on the road? “And anyway, no one will know,” Of course, it wouldn’t matter if there were just a few people in the world. But just think of all the millions of people saying to themselves: “It doesn’t matter. It’s just me. And, anyway, no one knows.” Millions of gallons of water would be wasted; millions of lights would be left on; millions of pieces of litter would be dropped. And all of this would be very harmful.
To inspire young people to take action for the environment, animals and their community, Roots & Shoots was established. This institute was set up in the early 1990s by Dr. Jane Goodall, a scientist who’s the world’s best-known expert on wild chimpanzees (黑猩猩). In addition to her research, she has been whole-heartedly committed to environmental protection, the whole purpose of Roots & Shoots is to educate young people, from preschoolers to university students, so they can help to build a future that is secure and live together in peace with nature. The organization is called Roots & Shoots because roots (根) move slowly under the ground to make a firm (坚实的) foundation, and shoots seem small and weak, but they can break open brick walls to reach the light. The roots and shoots are you, your friends and young people all around the world. Hundreds and thousands of roots and shoots can solve the problems, change the world and make it a better place to live in.
Do you think you help to make the world a better place when you make a sad person smile, when you make a dog wag (摇摆) its tail, and when you water a thirsty plant? One cheered-up person, one happy dog, one flowering plant, and you. That’s what Roots & Shoots is all about: the value and importance of each individual — human, animal or plant. Dr. Jane Goodall believes that the most important thing is that: “Every individual matters. Every individual has a role to play. Every individual makes a difference. You get to choose: Do you want to use your life to make the world a better place for people, animals and the environment? Do you want to make Roots & Shoots rooted in everyone’s heart? Do you want to be a part of a community for a shared future? You cannot be absent.”

4 . When it comes to endangered species, most of you may think of pandas. But did you know that bees are disappearing too? Last year, the US Fish & Wildlife Service added seven bee species to the endangered species list. What if bees die out one day?
Just in case they do, Japanese scientists have created a mini drone to pollinate (给……授粉) plants, just like bees, reported CNN.
The drone has a piece of horsehair with gel (凝胶) on it. The gel lets the drone pick up and put down pollen grains (花粉粒) from flower to flower.
The drone still needs to be improved. It cannot make honey or work without human help. The cost of up to$ 100(about 690 yuan)per drone is also high.
However, it’s still a meaningful exercise, because pollination is important for human beings. Without pollinators, fruit and vegetable production will drop by 23 percent and 16 percent respectively around the world, reported The Lancet, a UK magazine.
Bees are one of the most important pollinators, however, their numbers are dropping quickly. Bee numbers in the US have dropped by 30 percent in the past five years, according to Global Research, a Canadian research organization. The situation is similar in other countries.
Although scientists are still trying to find the cause, there are several possible reasons. First of all, more farmers are using pesticide (杀虫剂). Besides, different illnesses have caused the deaths of many different species of bees. Finally, global warming has changed the bees’ living environment.
In the future, scientists will use GPS and Al to improve the drone.

5 . What is sustainable travel? Traveling sustainably means being aware of the impact of tourism on the environment and following good practices to reduce the negative effects. Planet Earth has limited resources and mass tourism puts their existence at risk.
Let’s find out a few easy ways to travel in an eco-friendly way.
Stay in eco-friendly accommodations.
From renewable energy production to bio-architecture, eco-friendly accommodations focus on preserving the environment and have positive environmental effects.
Take public transportation.
Interaction with locals is one of the most rewarding things about sustainable travel and preserves traditions passed down from generation to generation. It is essential to respect traditions as they form the identity of the local community and create a sense of unity among people.
Say NO to single-use plastics.
Saying NO to single-use plastics reduces pollution. The production of plastics uses fossil fuels(化石燃料) and therefore releases carbon dioxide into the atmosphere, contributing to climate change.
| A．However, this is not all. |
| B．Buy from and support local businesses. |
| C．Respect the culture of local communities. |
| D．Therefore, sustainable travel is a way to preserve nature. |
| E．Traveling slow allows you to enjoy the scenery along the way. |
| F．This practice helps reduce air pollution and improve traffic flow. |
| G．In addition, numerous plastics end up in oceans every year, threatening sea life. |
6 . After a week of talks in Canada, negotiators (谈判者) from 170 countries have a “clear path to landing an ambitious deal” on plastic pollution at a final round of negotiations in South Korea in November, Inger Andersen, executive director of the U. N. Environment Programme, said in a statement.
“The work, however, is far from over,” she added. “Some countries continue to block a crucial measure: a global limit on the production of new plastic, which is essential to control pollution.”
Plastic is made from fossil fuels, and major oil and natural gas producers like Russia and Saudi Arabia have been widely criticized for throwing up roadblocks in the negotiations in order to protect future profits. However, scientists and environmentalists say the United States also bears a lot of blame. The country is the top producer of oil and gas globally, and it has the world’s biggest economy, which has historically given the U. S. huge power in environmental negotiations.
Critics say American negotiators haven’t been willing to push for a global cap (限额) on plastic production, and are instead throwing their weight behind measures like recycling that are favored by the country’s fossil fuel and petrochemical industries.
Erin Simon, head of plastic waste and business at the World Wildlife Fund who attended the talks in Canada, says the U. S. and a lot of other countries are brainstorming and trying to come up with creative solutions to meet everybody’s needs as best as possible.
The State Department has said that for an agreement to be effective, it needs to be supported by every country, including nations that are major producers of fossil fuels and plastics. More than 50 countries now say they want an agreement to include targets for reducing plastic production.
“The drumbeat to reduce plastic production is growing from countries worldwide,” Ana Rocha, the director of global plastics policy in Global Alliance for Incinerator Alternatives, said in a statement. “More and more leaders are waking up to what the science and our lived experiences tell us: plastic is pollution, and we need to stop it where it starts.”
1. What is the key to controlling plastic pollution according to Inger Andersen?| A．Limiting the use of second-hand plastic. |
| B．Raising people’s environmental awareness. |
| C．Reducing the worldwide production of plastic. |
| D．Passing laws to regulate the disposal of waste plastic. |

| B．The plastic pollution should be handled technically. |
| C．People’s awareness of reducing plastic pollution is increasing. |
| D．More leaders realize lived experiences can help handle plastic pollution. |
7 . In the vast desert plains of northwest Namibia, rhino (犀牛) trackers start a journey to monitor the desert-adapted black rhinos. These creatures, known for their poor eyesight, walk freely in this remote region.
Led by Sebulon Hoeb, the principal field office r of Save the Rhino Trust Namibia, the tracker carefully approach a grazing rhino named Matty 2. identified by his partner Ebson Mbunguha. Despite the windy conditions working in their favor, they maintain a safe distance, aware of the potential danger of encountering these massive animals.
Every day and night, devoted trackers and local community ranger s patrol (巡逻) the vast expanse of land, totaling 25, 000 square kilometers, where the desert-adapted black rhino thrives. Armed with extensive knowledge of the rhinos’ behaviors and characteristics, they carefully document their observations, contributing to conservation efforts and fighting poaching (偷猎), which remains a constant threat due to the high demand for rhino horns.
Despite challenges, Namibia’s community conservation model has succeeded in protecting the rhino population. By prioritizing the preservation of wildlife and ensuring local communities to benefit from their natural resources, Namibia has become a lighthouse of conservation efforts in Africa. Save the Rhino Trust, established in 1982, has played a vital role in this achievement, witnessing a remarkable recovery in the black rhino population.
The significance of community conservation is stressed by Namibia’s commitment to environmental protection, written in its constitution since gaining independence in 1990. With the establishment of shared conservancies covering over 20% of the country’s territory, Namibia has pioneered a sustainable approach that balances conservation with economic development.
For the rhino rangers who devote their lives to safeguarding these iconic creatures, the job is rewarding. Living under the vast southern sky, they bear weeks of tented living, braving the dangers of tracking rhinos on foot. Despite the challenges, their serious commitment ensures the continued survival of the desert-adapted black rhino, a testament to the power of community-driven conservation efforts in preserving Earth’s oldest mammals.
1. What is the primary role of the rhino trackers?| A．To relocate rhinos to other habitats. |
| B．To record the exact population of rhinos. |
| C．To offer rhinos food when necessary. |
| D．To learn about the current situation of rhinos. |
| A．They favor windy conditions. | B．They will go extinct. |
| C．They are easy to approach. | D．They can be violent. |

| B．The challenges facing rhino trackers in Namibia. |
| C．The history of rhino poaching in Africa. |
| D．The dangerous situation of rhinos. |
8 . Wild African elephants may break sleep records for mammals (哺乳动物). New data show that they seem to survive on about two hours of shut-eye a night. Much of that sleeping took place while they were standing up. The animals lie down to sleep only once every three to four nights.
Trying to figure out how much wild elephants sleep just by watching them 24 hours a day is tricky, especially in the dark. Much of what scientists had known about sleeping elephants came from animals living in zoos, notes Paul Manger, who is a brain researcher at the University of the Witwatersrand in South Africa. In zoos, elephants have been recorded sleeping from about three hours to nearly seven during a 24-hour period. Using electronic monitors on African elephants in the wild, however, has turned up more extreme behavior.
Manger’s team implanted (植入) activity monitors in the trunks (象鼻) of two elephants. Both were female leaders of their herds in the Chobe National Park. Trunks, like human hands, are important for exploring the world. Elephants hardly keep them still — unless sleeping. The researchers thought that a trunk monitor that didn’t move for at least five minutes likely meant its host was asleep.
The monitors tracked the animals over about a month. During that time, the elephants averaged just two hours of sleep a day. What’s more, the elephants were able to skip a night’s sleep without needing extra rest the next day. Those trunk implants showed there were times when the elephants went up to 46 hours without any sleep.
There has been some thought that animals need sleep to store memories properly. But that can’t explain animals, like the elephants, which skip sleep for a night without needing catch-up rest later. “Elephants are usually not considered to be forgetful animals,” Manger observes. In fact, he notes, studies have found that they can have long memories.

9 . As I stand in my favorite craft store, I’m faced with choices that mirror the world outside. You see, I love my foam (泡沫橡胶) board, which has foam inside and is sandwiched between two layers of paper or plastic. It’s easy to work with and affordable, but not friendly to the environment. Or take a look at the paintbrushes. The plastic handle brushes are cheap while the brushes with wooden handles cost a fair bit more.
Glues are the unsung heroes of my art, yet their plastic containers are far from eco-friendly. And don’t get me started on the packaging that these art supplies come in. It’s all plastic, and it’s a reminder that even in the art world, being green isn’t always easy.
As an artist, I’m not exactly rolling in profits. Most of what I earn goes right back into my materials, leaving little room for choosing green materials. Fresh out of university, I am still searching for a job. Since I currently don’t have a regular income, I’m living with my family to save costs and paying careful attention to what I can afford. But I also care deeply about climate change, since I’ve seen its impact and can’t bear the thought of it getting worse.
So, to reduce my personal impact on climate change while also living within my means, I make full use of my brushes until they’re on their last hair, and I’ve become a master at repurposing cardboard boxes and various packing materials. The firm plastic packaging that once housed my paints finds a second purpose as glass in my miniature (微型的) windows. The cardboard from those boxes’ serves as bases for a range of miniatures. I don’t waste a bit of foam board either; it’s kept for crafting mini-books for my sets.
It’s an ongoing process — a journey of give and take. While I try to reduce my ecological footprint, I am also learning to balance practicality while enjoying creating my own art.

10 . Blood may be thicker than water when it comes to human relationships and it appears that the same is true of jackdaws (寒鸦) after scientists found they readily switch friends to gain food but stick with family even at the risk of going hungry.
Alex Thornton, a professor of cognitive evolution, said, “We monitor hundreds of wild jackdaws, each of which is fitted with a tiny PIT tag like the chips (芯片) used for pet cats and dogs — embedded in (嵌入) a leg ring. In this experiment we randomly divided jackdaws into two groups — A or B — and programmed a pair of automated PIT tag-detecting devices to provide worms only if individuals from the same group(AA or BB) visited together.” If birds from different groups arrived together — A with B — the feeders would remain closed. Single birds would get grain, but not the more desirable worms.
Thornton said, “The idea was to find out if jackdaws could readjust their social associations. They might have friends in the wrong group. Do jackdaws ditch them and start to hang out with individuals who are in the right group? The jackdaws turned out to be very strategic, quickly learning to abandon friends from the other group so they could get the best rewards. However, they made an exception when it came to their close relations even if they got nothing. What we were able to do here was test the idea: can individuals keep track of the outcomes of past interactions and update their relationships? It turns out they can.”
Thornton said jackdaws were an excellent subject matter as they were clever and had dynamic social networks. “You’ve got individuals coming and going so beyond their strong relationships, and they have lots of other associations. They are similar to human society.” Michael Kings, of the University of Exeter, said, “These results help our understanding-of the evolution of intelligence as they show that being able to track and remember information about social partners can bring benefits.”
