1 . The fruit-tree pinhole borer (针孔蛀虫), as its name implies, makes holes in fruit trees. It lays its eggs and raises its young in the galleries thus created . Yet the beetles (甲虫) do not feed directly on the wood they bore into. Instead, they devour fungi (真菌) that grow on the wood thus exposed.
Researchers have long suspected that this is a form of farming, because they have evidence that the beetles carry spores (孢子) of their preferred crop, R. sulphurea, into their smallholdings—in effect, sowing it there.
Observations of natural fruit-tree pinhole-bore r dwellings suggest that R. sulphurea grows in them more abundantly (大量地) than might be expected, given all the fungal competition around—but not why. To check whether the beetles are, indeed, weeding their crop, Janina Diehl and Peter Biedermann of the University of Freiburg did an experiment.
In the laboratory, they had mother beetles of the little wood bore restablish nests, in which the typical fungal gardens formed. But before the beetles had started laying their eggs, they collected all of the beetles and then returned half to their dwellings while leaving the other nests empty. Genetic analysis of the fungal gardens after 40 days showed that the presence of the beetles had greatly changed the fungal community. Twenty days after that, they sampled the gallery walls for fungi.
As they had hoped and expected, R. sulphurea was much more abundant in beetle-tended galleries than in those without residents. In the former, it made up half of the fungal mass extracted. In the latter, less than a third. These beetles are indeed weeding their crop.
“Further research into how exactly the beetles suppress the growth of weed fungi could alsoprovide worthwhile insights for human agriculture, which is struggling with weed resistance, for example,” says Biedermann. “It’s highly exciting for us to see how nature has been doing this for 60 million years. We humans can still learn something from these mechanisms.”

My sister-in-law Carol said she’d already picked out a kitten for me. I agreed to go with her… just to look. I made no promise to take one home. After all, only two months had passed since I lost my beloved calico cat, Mandi. Maybe I needed to be pet-free for a while.
When we got there, three of the four kittens remained in the litter. Carol picked up one and handed it to me. The beautiful face and white fur on the right side of her nose reminded me of a clown-like mask. How could I resist? Then another kitten, with an evenly balanced white face, jumped into my lap and purred.
Driving home in my British sports car proved difficult with two mischievous kittens. One clung to my left arm and shoulder, watching the fast-moving scenery outside. The other paced back and forth from my lap to the passenger’s seat, making it hard for me to shift gears. Both mewed in a loud duet(二重奏) of protest. Of course, I hadn’t brought a cage. I had not planned to take home a kitten — or two.
The clown-like-masked female earned the name Squeakette with her tiny voice squeaking about each new discovery as she explored her new home. The male, lacking only a black tie in his formal clothes, took the name Sebastian for my favorite composer, Johann Sebastian Bach.
A few weeks later, a neighbor helped me carry down my six-foot artificial Christmas tree from the attic(阁楼). I thanked him with a batch of cookies, and then set up the tree in the comer of my living room.
Sebastian and Squeakette knocked it down before I opened the box of decorations. After setting it upright, I straightened the few bent wire branches back into place. As I checked for any other damage, a quick flash of black-and-white fur passed by me. Up they went, branch by branch. The tree danced around as the two kittens took turns climbing it together. Sebastian made it to the top a moment ahead of Squeakette.

3 . Several security guards of residential compounds in Beijing and workers were seen shoveling snow and some parked vehicles were covered by thick overnight snow. The first snowfall of winter arrived in Beijing early Monday, covering the Chinese capital with a mantle (披风) of white overnight and plunging (使……下降) the city into freezing temperatures, with even colder weather coming this week in northern China.
Snowfall reached 5.8 mm on average by early Monday, with the highest snowfall of 10.2 mm recorded in Fangshan district, Beijing Meteorological (气象的) Service data showed. Beijing typically sees its first snow of the season between late November and February, or even none at all. More snowfall is expected this week, with temperatures seen further sliding to as low as -20°Celsius. The Chinese capital last saw such similarly extremely cold weather on Jan. 7, 2021, when the temperature dropped to -19.6℃.
The cold snap (寒潮) in Beijing this week, compared with the autumn-like conditions a week ago, mirrored the sharp swings in temperatures recently. In October, Beijing experienced one of its warmest Octobers in decades in a year of weather extremes.
On Monday, the government warned of road icing in large parts of the city of nearly 22 million, with authorities shutting some expressways or partially closing sections. By 10 a. m. local time, 62 out of a few hundred flights had been cancelled at the Beijing Capital Airport. Railway authorities enforced speed limits on lines connecting Beijing and Guangzhou in southern China, causing delays in some passenger trains. By 7 a. m. Monday, more than 180 bus routes in Beijing had been suspended.
The official Beijing Daily reported that vegetable stocks were enough, hitting this year’s highest daily market volume of 23,800 tons, as merchants stocked up (备货) ahead of time. Huang, a Beijing resident working in the internet sector, said the snow in Beijing came early. “Normally, it doesn’t snow until the Spring Festival,” Huang said, referring to the start of the Lunar New Year, which typically falls in January or February.
1. Which of the following is not used to show the seriousness of the snowfall in paragraph?| A．By listing out numbers. | B．By illustrating a viewpoint. |

4 . For the first time in about 100 years, a rare bird called the takahē is walking freely along the Lake Whakatipu Waimaori Valley in New Zealand after 18 captive birds were released into the wild. The area is also home to a Maori tribe called Ngai Tahu, which has spent years campaigning for the birds to return to their land. The Maori are New Zealand’s Indigenous people (first people known to live there), and they consider the takahē bird to be “taonga”, meaning a treasure.
Takahē are large, round, flightless birds with red legs, and they have lived in New Zealand since prehistoric times. Like many New Zealand birds, takahē evolved to be flightless because there were no mammals to compete with. When Europeans arrived in New Zealand, however, predators such as cats and ferrets were introduced and killed off many flightless birds. Takahē were declared extinct in 1898, but a small number of the birds were discovered in 1948 in a remote part of the Murchison Mountains.
Since then, conservationists have been trying to restore the takahē population in captivity. They gathered the bird’s eggs in order to keep the chicks safe from predators. The chicks were raised by volunteers, who fed them while wearing sockpuppets on their hands to imitate the parent birds. There are now about 500 takahē birds in captivity. Several pairs of adult birds have been released into the island’s sanctuaries and national parks. Experts will monitor them to see how they adapt to their new environment. If everything goes well, they hope to release seven more birds this month and 10 young birds next year.
Ta Tipene O’Regan, an elder of the Ngai Tahu tribe, helped to release the birds. He told The Guardian newspaper, ”There are few things more beautiful than to watch these large birds running back into lands where they haven’t walked for over a century. ”O’Regan said, “It’s an absolute joy. ”

In the grip of a cold wave, with temperatures plummeting below minus 10 degrees Celsius, the plateau county of Jishishan in Northwest China’s Gansu province was jolted from its slumber midnight Monday by a 6.2-mngnitude earthquake, causing death,

Members of the Gansu branch of the Blue Sky Rescue Team,
In Dahejia township,
One spring, I was hired as groundskeeper at a Country Inn, a famous bed-and-breakfast located in Washington state. The grand house is in a beautiful place. Many famous people have visited and even had their own rooms there. The owners, Philip and Cecelia, have done a perfect job for the house. However, the gardens were very overgrown. Worse yet, there was another problem: a very persistent doe (母鹿).
Every day when I came to work, there was new evidence of the deer’s big appetite. I tried many preventives: spray, human hair, soap, you name it-but none of those things had effect. Often when I was weeding, I’d look over and there she’d be, munching some tasty pieces. Worst of all, she feasted on the roses, in which Cecelia took great pride. I became so frustrated that I named her “Dinner”— and wanted to serve her on plates.
One morning, I was on my hands and knees pulling out vines and bushes when I caught a movement out of the corner of my eye. There was Dinner, not five feet away, munching a large leaf and staring at me. I felt a connection with this animal. We did have something in common-we were both mothers. I got the crazy idea of communicating with her and it seemed she wanted the same thing.
What’s up? I asked in my head.
I’m here because I feel safe, was the gentle reply I felt I heard. I have my fawns (幼鹿) bedded down nearby, and there is plenty to eat. When the twins are older after summer, I will move them deeper into the forest.
I understand that, I assured her. People come here too, from far away. I guess they’ll be interested to see you. I promise that nobody will harm you or your children. I don’t mind sharing the vegetation but Cecelia loves roses, too. She is very upset when they are all eaten.
A loud crash broke the magic. Our eyes met again briefly before she leaped off across the driveway, disappearing into the forest. Has I really communicated with the deer?
Paragraph1.
I went into the kitchen where Cecelia was preparing the evening meal.

7 . Growing up on a mountain farm in Tyrol, Fritz enjoyed watching how cows and horses interacted with each other more freely, once they’d been led out of the barn and into pasture. It was what he observed in his boyhood that took root in his pursuit of becoming a biologist. After he finished his study at university. Fritz landed work at Austria’s Konrad Lorenz Research Center, raising raven chicks by hand and teaching graylag geese how to open boxes as he pursued his PhD. Working this closely with free-living animals was exactly what he’d dreamed of as a boy.
In 1997, a zoo gave the research center its first northern bald ibis chicks (隐鹮) Nowhere near as teachable as geese—and not even close to super intelligent ravens—the ibises frustrated most of the scientists. But Fritz was fascinated. He devoted himself to taking care of them. After the ibises were first released back into the wild more than 20 years ago, Fritz learned that spending generations in zoo hadn’t reduced their drive to migrate (迁徙), though it did leave them geographically uninformed. In their search for “south”, some ended up in Russia. What the ibises needed, Fritz thought, was a guide.
Fritz decided he would teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. And he was confident he could succeed in this daring, unconventional plan—because he had done it before. “Around that time, the movie ‘Fly Away Home’ was a huge hit with us biologists,” Fritz says. When he announced that he’d do the same with the ibises, he was initially laughed at. But Fritz didn’t give up. He modified an ultralight aircraft so it would travel at speeds slow enough for his winged students to keep up. He had been his young pupils’ only provider of food, love and hugs since they were just a few days old, and the ibises eagerly followed their teacher, who just happened to pilot a fairly noisy machine.
In 2004, three years after some initially bumpy (颠簸的) experiments, Fritz led the first batch of birds from Austria to Italy, and has since led 15 such migrations. Over that time, he has rewilded 277 young ibises, many of which then started to pass the route on to their own young.

8 . Conservation organization Plantlife is urging people to put away their lawnmowers (除草机) for a month and let wild flowers grow instead, as part of its No Mow May project.
Leaving the grass uncut will create a habitat that will benefit bees and other insects, the organization says. Plantlife says lawns could be biodiversity hot-spots if left alone. It says those who participated in its campaign last year reported the growth of more than 250 plant species on their lawns. Among these were wild strawberry and wild garlic. There were also sightings of declining species like green-winged orchids.
One gardener who has been enjoying a more relaxed approach is Tom Jennings, 45, from Buckinghamshire. He says it’s a chance to reconnect with the natural world. “Those fascinated by neat gardens use not only lawnmowers but chemicals.” says Tom.
After letting his back garden grow out, Tom witnessed an explosion of wild flowers—important for pollinators (授粉者) such as bees. Tom says he’s been shocked at how quickly insects have returned to his back garden: an encouraging signal given the global decline of insect populations.
According to Colette Webb, 42, who lives in West Sussex, there are added benefits to letting nature gradually take its course in the garden. “It saves you a bit of time and arguments with the husband about getting the lawnmower out—something my husband hates doing,” she says. “There’s a part of me that thinks the garden is really messy, but when you sit there for some time a day and look at what’s it’s supporting, you realize it’s for the benefit of nature.”
But not everyone is on board with the idea, says David. One of his neighbours is pursuing their own re-wilding project in their own garden—but the other is yet to be convinced. “And my mother, who’s 81, still says it looks untidy,” he laughs.

9 . Recently, China has announced the list of the first five national parks. Each of them is divided into two parts — the core protection area and the general control area. In the core protection area, only research and surveillance (监视) in science are allowed. And the general control area is open to the public, allowing travel activities such as camping and hiking. In the future, national parks are expected to be natural classrooms. People can learn about different kinds of animals and plants through eco-friendly travel activities.
Three River-Source National Park on the Qinghai-Tibet Plateau is the largest national park in China. Because it is home to the sources of the Yangtze, Yellow and Lancang rivers, people call it “China’s water tower”.
Northeast China Tiger and Leopard National Park is in Heilongjiang and Jilin Provinces. It covers an area of 14,100 square kilometers. It is our country’s biggest and only place for wild Siberian tigers and Amur leopards to live in.
Wuyi Mountain National Park in Fujian Province is a UNESCO natural and cultural heritage site. The forest makes up over 96 percent of the park. The park is the paradise of birds, kingdom of snakes and world of insects. You can also see the Danxia landform there.
Giant Panda National Park connects panda habitats in Sichuan, Shaanxi and Gansu Provinces. Inside the park are more than 1,600 wild giant pandas. They make up over 70 percent of the pandas in China.
Hainan Tropical Rain forest National Park is the largest tropical forest in China. There are more than 400 kinds of plants that can only be found in Hainan.

10 . An impressive invention made by a 17-year-old teenager, called Anna Du, is helping to clean up small pieces of plastic from the ocean.
While walking along her local beaches in Massachusetts, the young student began collecting waste plastic bags and bottles. But what she noticed was a large number of tiny pieces of plastic or microplastics that were impossible to pick up. At just 12 years old, Du set out to solve the problem. After testing a few prototypes(原型)in her backyard, she invented a remotely operated vehicle that uses the infrared camera(红外摄像机)to detect microplastics on the ocean floor. More recently, Du has also created a simulation(模拟)model that uses artificial intelligence to predict where microplastics are located.
Du’s robot invention has earned her awards at top science fairs in the US, and she’s now a nationally recognized advocate for microplastic awareness and pollution prevention. “When I first started doing science fairs, I had no idea that a young girl without lots of money and just a little advanced engineering knowledge could make a difference in the world. I’ve learned that I truly love working on a problem that’s so much larger than me,” Du said.
Du has also released a new book to help spread the word not only about the dangers of microplastics but also about the ways to relieve the problem. Titled Microplastics &Me, the book follows Du’s own story of how she went from worrying about the environment to designing award-winning solutions. Writing for kids her own age, the young girl alerts her readers to the threat of microplastic pollution and urges them to care about the environment. The book hopes to encourage young students to get into science, technology, engineering and math(STEM)subjects and to inspire a new generation of inventors and engineers. What’s more, Du has even raised more than $7,000 to distribute the book free to kids and libraries in high-need communities.
1. What inspired Du to make the invention?| A．There was too much rubbish along the beaches. | B．The plastics were too small to collect by hand. |
| C．The sea was polluted seriously. | D．She was interested in AI. |
