Allen was playing in his room. He heard a familiar chirping and rustling from the cage in the bedroom corner. It was his beloved Blue Finch, named Mary. The boy had cared for the bird since he was six, a gift from his mother for graduating from kindergarten and entering primary school. Now, at 12 years old, Allen had just recently celebrated his primary school graduation and was about to take another step in his life journey toward junior high school. For the past six years, Mary was his constant companion and closest friend.
As he grew up, Allen found it difficult to make friends or be close to others. Having had to move around many times and transfer schools due to his father’s work in the military, Allen never felt like he truly belonged in any one place. He always knew it wouldn’t be long before he would have to move yet again. The stress and pressure of a constantly mobile life also led to strain and pressure at home, leading to loud arguments and fights between his mother and father which he could hear from behind closed doors.
But, throughout all of this. Allen’s closest friend and companion-the true source of stability in his life — was Mary, his finch. But Mary was more than just a simple, calm pet: whenever Allen felt sad, the bird would always be singing and chirping, almost as if she sensed how he felt and wanted to lift his spirits. And when Allen fed the bird, Mary always moved across her branch to rest against his finger, never failing to bring a smile to Allen’s face. Yet, one summer day after Allen had come home after a walk at the park he found the window of his bedroom open and the door of Mary’s cage open-the-bird was gone. Suddenly, Allen realized that he must have left the cage open after cleaning it and forgot about the window being open on such a hot day. Upset, Allen fell down to the floor sobbing.

Baby seabirds that have not yet hatched communicate with their siblings (兄弟姐妹) in neighbouring eggs by vibrating (震动) their shells, scientists have discovered.
A study of yellow-legged gul s revealed one of the known examples of embryonic (胚胎期的) communication. When exposed to the alarm calls of an adult bird responding to a predator (捕食者) , developing chicks apparently were able to convey the presence of danger to their nest mates by vibrating inside their eggs.
The team collected 90 yellow-legged gull eggs from Sálvora Island and sorted them into nests of three. When the eggs were six days off hatching, two of the three eggs in each nest were temporarily removed from the nest and exposed to either a recording of a predator alarm call or white noise each day until the chicks hatched. The noise was delivered four times a day at random for three minutes at a time. The third egg from each group remained in the nest.
It was found that the embryos responded to the external alarm calls by vibrating or and vocalizing (发声) less — and that this in or matin appear d to be passed on to the third nestmate. It was seen to copy the vibrations. It also underwent genetic changes and had an increase in the production of stress hormones (荷尔蒙).
“This kind of communication — embryo to embryo — can generate developmental changes that can have potential benefits to the birds after hatching,” said Noguera, the lead author of the study.
A rise in stress hormones makes birds more aware of their surroundings after hatching. When hatched chicks were exposed to alarm sounds, it was found that those who had listened to the noises previously in the egg were quicker to run away and hide.
Noguera said the phenomenon was likely to occur in other bid species. His team now plans to investigate whether the chicks are able to pick up other clues about their external environment before hatching, such a show many other eggs are in the nest.

4 . I met the Man of the Trees in summer ten years ago, when I was visiting Uncle Jita.
Those were difficult times. People were cutting down our forest, and there was often flooding. Sometimes our water supply was dirty. When our pump(水泵)did have clean water, we had to wait in line for ages. When the pump wasn’t working, we had to walk five kilometres to the closest stream.
But I was happy. I was going to see my favorite uncle. When the day finally arrived, Dad drove me to Uncle Jita’s house and left. Once he saw me, Uncle Jita announced, “Tomorrow we’re going to explore a magical place. Here is my camera, Amy. You can take photos of what you see.”
The following day, we woke up and left early on a boat. The trip was exciting. But when we got off, there was ... nothing in front of us. “I don’t want to take pictures of this,” I complained.
Uncle laughed,“Start walking, Amy. I promise you’ll be surprised.” After some time, I could see the outline of a forest in the distance. A little closer, there was a man waving to us.
“That’s Kabir. The forest you see is his. He planted every single tree.” As we walked towards Kabir, Uncle explained that thirty years ago, the whole area was a wasteland. But one day Kabir decided to change all that and started planting trees. Thanks to him, part of the wasteland is now a paradise(天堂).
Uncle introduced me to Kabir, who had gray hair and a determined face. “Jita told me you like animals. Are you ready to see some?” he asked. “Of course!” I replied. We continued walking and soon were under the trees. I turned my head and was amazed at the difference between the two places. All because of the efforts of one man.
Like Uncle said, Kabir’s forest was magical. We saw deer, rhinos, and even tigers. During lunchtime, Kabir explained how, by planting trees, it was possible to stop the land from eroding(侵蚀).

The streets of Cotonou, Benin’s largest city, have been Domingo Soule’s workplace for 35 years. The 50-year-old motorcycle taxi driver spends his days driving for miles on roads blanketed in exhaust fumes (尾气), picking up customers and taking them to where they want to go. But Soule has developed a cough from breathing in air pollution, he believes, and at the end of each day his eyes hurt.
Things maybe about to change, however. In recent months, he’s seen more and more electric motorbikes on the streets of Cotonou. The Indian manufacturer (制造商) M Auto introduced its electric bikes in Benin in July 2022 and there are already 2,000 on the roads; an additional 2,000 people have paid deposits (定金) and are waiting for delivery.
Shegun Bakari, M Auto’s chief executive, has ambitions to get all moto-taxi drivers in Benin to switch to electric. This month he plans to launch a campaign to encourage them to swap (交换) their old bikes for new electric models.
The only sticking point is the battery. M Auto’s business model relies on “swap stations” throughout the city. When the battery runs out after about 60 miles, drivers must visit a station and pay to exchange the empty battery for a full one. Concerns about the battery are also preventing Soule form buying an electric bike. It could cost him 4,000 CFA ￡(5.40) a day to replace batteries, Soule says, whereas at the moment he can buy five litres of petrol (enough for one day) for 3,000CFA.
Bakari understands his concerns. In Beni, close to 40% of the population live under the poverty line, earning less than US$2 a day. “If I’m living with $2 a day, I can’t afford to pay more just because I want to save the planet,” he says.
He and his team are working to persuade governments in Africa to reduce taxes on electric vehicles, as well as putting plans in place to produce the electric bikes in Benin. They are also in talks with the government to build a solar plant to provide the extra energy that will be needed.

6 . Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue, but these gains are fragile, a new study suggests. Researchers found that these accurate beliefs fade quickly when people are exposed to coverage skeptical of climate change.
“It is not the case that the American public does not respond to scientifically informed reporting when they are exposed to it,” said Thomas Wood, associate professor of political science at the Ohio State University. “But even truly accurate science reporting recedes from people’s frame of reference very quickly.”
Results showed that accurate science reporting didn’t persuade only politicians and people who initially rejected human-caused climate change also had their opinions shifted by reading accurate articles. The study involved 2,898 online participants who participated in four waves of the experiment during the fall of 2020.
In the first wave, they all read authentic articles in the popular media that provided information reflecting the seientifie views on climate change. In the second and third waves, they read either another scientific article, an opinion article that was skeptical of climate science, or an article on an unrelated subjeet. In the fourth wave, the participants simply were asked their beliefs about the science of climate change and their policy attitudes.
To rate participants’ scientific understanding. the researchers asked after each wave if they believed that climate change is happening and has a human cause. To measure their attitudes, researchers asked participants if they favored government action on climate change and if they favored renewable energy.
“What we found suggests that people need to hear the same accurate messages about climate change again and again. If they only hear it once, it recedes very quickly,” Wood said. It was significant that accurate reporting had positive effects on all groups, including those who originally rejected climate change. But it was even more encouraging that it affected attitudes.

7 . During World War II, Duchess Nina Douglas-Hamilton played a vital role in looking after animals.
As the war broke out, the government issued orders for the mass killing livestock (家畜) to prevent them from being captured or destroyed by the enemy. Duchess Nina launched a campaign to save as many animals as possible, and soon became known as the “animal heroine” for her efforts.
Duchess Nina worked with local farmers and animal owners to relocate animals to safer areas, such as the Scottish Highlands. She also established a network of volunteers who helped to care for animals during the war. She organized feeding programs, medical care and transportation, ensuring that animals were well looked after even during the most difficult times. The most challenging aspect of her work was the shortage of food during the war. So she established a vegetable garden and used leftovers to create nutritious meals for animals. She also reached out to the public for donations of food and supplies, and was able to secure enough resources to keep animals healthy and fed.
In addition to her work with domestic animals, Duchess Nina was also a strong advocate for wildlife conservation. She established a center for wild animals Scotland, where she provided a safe place for deer, foxes and other animals that were threatened by the war. She also worked with local protection groups to protect natural habitats.
Duchess Nina’s work during World War II was not without its risks. She frequently risked her life to save animals, often driving through perilous areas.
Sadly, some people saw her efforts as a distraction from the war effort. However, she continued to work tirelessly for animals. After the war, Duchess Nina’s work was recognized by the government and she got an important award for her services to animals.
1. How did Duchess Nina probably feel when she heard the government’s orders?| A．Calm. | B．Worried. | C．Excited. | D．Encouraged. |
| A．Nobody gave her any donations. |

8 . Research led by ecologist Bart Hoekstra of the University of Amsterdam shows that birds are affected by the mass use of fireworks on New Year’s Eve up to a distance of 10 km (6 miles) away.
With data from weather radars and bird counts an international team of researchers revealed how many birds take off immediately after the start of the fireworks, at what distance from fireworks this occurs and which species groups mainly react. “Birds take off as a result of an acute flight response due to sudden noise and light. We already knew that many water birds react strongly, but now we also see the effect on other birds throughout the Netherlands, ”says ecologist Bart Hoekstra of the University of Amsterdam. In the scientific journal Frontiers in Ecology and the Environment, the researchers therefore argue for large fireworks-free zones.
Last year, other researchers at IBED discovered that geese are so affected by fireworks that they spend an average of 10% longer looking for food than normal during at least the next 11 days. They apparently need that time to restore their energy to their former condition, after fleeing from the fireworks.
Because 62% of all birds in the Netherlands live within a radius of 2. 5 km of inhabited areas, the consequences of fireworks are high for all birds throughout the country. “Flying requires a lot of energy, so ideally birds should be disturbed as little as possible during the cold winter months. Measures to ensure this are especially important in open areas such as grasslands, where many larger birds spend the winter. The effects of fireworks on birds are less pronounced near forests and semi-open habitats. In addition, smaller birds such as tits and finches live there, which are less likely to fly away from disturbance.”
The authors argue for fireworks-free zones in areas where large birds live. Hoekstra: “These buffer zones could be smaller in areas where light and sound travel less far, such as near forests. Furthermore, fireworks should mainly be lit at central locations in built-up areas, as far away from birds as possible. It would be best for birds if we moved towards light shows without sound, such as drone shows or decorative fireworks without very loud bangs.”

| B．It’s conducted by collecting data from weather radars. |
| C．It shows the extent of the fireworks’ influence on birds. |

10 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair（婴儿车）, she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.
The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma（哮喘）.
Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."
“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets（小装置）. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution？'So we did it."
Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."
