1 . In a Parisian old shoe factory on the city ‘s outskirts, a new kind of life is taking root. Neoplants, a startup from Paris, has developed a special houseplant that could potentially help improve indoor air quality by removing harmful pollutants.

The plant is a modified variety of one of the most popular and low-maintenance houseplants. Its DNA has been altered to enhance its capacity to absorb volatile organic compounds (VOCs) from the air we breathe inside our homes. These VOCs include substances like formaldehyde, benzene. toluene. ethylbenzene, and xylene, which are commonly found indoors and can be harmful in large quantities.

The genetic tweaking also allows the plant to convert the absorbed VOCs into substances it can use. such as sugars and carbon dioxide, which then fuel its growth. While Neoplants’concept is quite promising, proving its effectiveness is a challenge.

Plant shops often claim their greenery can purify the air, but much of this belief stems from research conducted by NASA back in 1989. They found that houseplants could indeed absorb certain toxins. However, achieving the same level of toxin removal as simply opening a window would require an impractical number of plants—anywhere from 10 to 1.000 per square meter.

So, does Neoplants’genetically modified houseplant offer a better solution? Field tests haven’t yielded definitive results yet, but there is hope for more conclusive testing in the future with the help of a new lab equipped with unique non-absorbent rooms that mimic real-life conditions . Additionally, the company is exploring potential applications for its gene-editing technology in areas such as carbon capture and phytoremediation, where plants are used to clean up contaminated environments

Neoplants is relying on patience and a bit of faith. It takes time for innovations to mature. “This will be the first time such a product exists.” says the company’s CEO. drawing a parallel to the early days of computers, which were not very powerful initially but still represented a significant breakthrough.

With Neoplants’ vision, the old shoe factory on the edge of Paris isn’t just a place where shoes were made; it’s where a novel approach to cleaning our indoor air is being cultivated—one that could someday make our homes healthier and more environmentally friendly.

Longmen Grottoes

Set on the banks of the Yi River, 12km south of the current Luoyang City, the Longmen Grottoes are ranked first of the Four Great Grotioes in China, together with Mogao Grottoes in Dunhuang, Yungang Grottoes in Datong and Mount Maiji Grottoes in Tianshui. They were also listed in the World Cultural Heritages and Relics by UNESCO in 2000.

    1     (Locate) between the Xiangshan Mountain and the Longmen Mountain, with the YiRiver flowing below, the Longmen Grottoes are     2     (harmony) with mountains, forests and rivers displaying a peaceful atmosphere. Viewing it at a distance, it looks like     3     natural gate, which gave it the name “Yi Que (the gate of the Yi River)”. According to legend,     4     Emperor Yang of the Sui Dynasty climbed on Mount Mang north of Luoyang, he was very pleased and ordered the eastern capital     5     (build) here with its palace gate opposite the Yique. Thus, it came to be named, Longmen Gate.

Longmen Gate also houses     6     (rough) 2860 stele inscriptions (碑刻), making     7     a treasure for ancient calligraphy study. In total, more than 100,000 Buddhist statues and niches     8     (carve) into the cliffs by ancient Chinese people ranging from the largest one, the Vairocana Buddha with a     9     (high) of 17.14 meters,     10     the smallest one of 2 centimeters.

Wandering in the Longmen Grottoes, one is amazed by the delicate carving skills, deep Buddhist culture and great art achievements of Chinese people.

3 . My family always had some sort of animal around, but none of them were truly mine. My parents didn’t permit me to _________ my own until I was seven years old. Finally, I was _________ to have my own _________, a fish called George. I said it was my responsibility to _________ it.

Every Friday I would clean out his bowl. I found myself _________ invitations to go somewhere immediately after school, because I would have to feed my fish first. Every day he would remind me that I was _________ and that I had someone depending on me.

One day, I came home from school and headed to my room to _________George. I found a _________ thing had happened. I _________ my bag and ran over to the bowl. I saw my best friend George floating around lifeless.

My mom walked into my room. I turned around as tears started to well in my eyes. “Mommy, George d…d…died.” With that __________ word I started crying uncontrollably. My mom came to my side as I hid my face in my pillows.

Suddenly, I realized that George hadn’t just __________ me. He had taught me what __________ meant. I learned it through feeding him and cleaning his bowl. This made me feel __________ . To my seven-year-old self, this was a great __________ . Slowly, a smile crossed my face. George was gone.__________ , the lessons he taught me would forever be carved into my memory.

5 . 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.”

Nature’s Lungs

We know that trees are nature’s purifier (净化器): They absorb carbon emissions (碳排放)and release oxygen. But their     1       (able) to do that changes as they age. According to Newsweek, trees     2       are at least 20 years old can absorb carbon better than younger ones and older ones. And a recent study by researchers from South Korea’s Forest Research Institute     3       (find) exactly how much carbon that each 25-year-old cherry tree can absorb: 20 pounds (9.1 kilograms) each year.

According to the study, there are     4       (current) about 1.5 million cherry trees in South Korea, which means they can take in as much as 13,650 tons of carbon each year.

This may sound like a lot,     5       it’s only the annual emissions of 6,000 cars. And it’s pretty     6       (shock) if you think about it: The annual emissions of a single-car requires 250 mature cherry trees to absorb     7       carbon.

Yet, planting trees is still considered the most effective way     8       (reduce) global warming, according to Professor Tom Crowther of the Swiss university ETH Zurich. “Forest restoration isn’t just one of our climate change     9       (solution), it’s the top one,” he told the Guardian. “What blows my mind is the scale. I thought restoration would be in the top 10, but it is much    10     (powerful) than all of the other climate change solutions proposed.”

7 . On Sunday night, the police found a baby koala in a bag in the town of Wishart in Queensland, Australia, during a traffic stop. Queensland police spokesperson Michael Beatty said that the officers asked a 50-year-old driver if she had anything to report. She then told the officers that she had a baby koala in her bag.

“Not quite believing their ears, the officers cautiously opened the bag and found this lovely boy and we’ve called him Alfred,” the spokesperson said. “The young koala is about 6 months old and weighs 1.5 kg. It appears to be healthy, though it was very thirsty.”

The police are warning people who find koalas to turn them over to authorities, rather than try to take care of them themselves. Koalas are protected in parts of Australia, including in Queensland, where they have been listed as “threatened” under the Nature Conservation Act.

Of course, koalas are also violent animals. One particularly wild koala even attacked a farmer in South Australia when she was riding along a muddy road.

“As it started running towards me, I thought I’d better speed up,” the terrified farmer told reporters. “But the road was too muddy, So I abandoned my bike and ran away. Fortunately, it ran up and attached itself to the dirty wheel — perhaps mistaking it for a eucalyptus tree.”

Deakin University biologist Desley. Whisson has some tips in case you experience this predicament. “Koalas more generally run from than to people. The farmer did the right thing by moving away from her bike,” she said. “The best advice I can give to people is to not fight with a koala displaying unusual behaviour. Make sure that there is another object between you and the koala so that it can’t climb you. Or you can just simply run. Their fingers are very sharp.”

She also believed the koala might have been confusing the sound of the bike with that of a koala mate.

Over the summer break, a wave of fashionably     1     (dress) young people went to Kaifeng in Central China’s Henan province to explore the city     2     was the ancient capital of eight dynasties through a trendy “Citywalk”. They     3     (eager) shared fresh perspectives and travel encounters on various social media platforms.

“Citywalk” means the act     4     walking freely along city     5     (street) free of large and heavy bags. Such a convenient form of travel has emerged as     6     popular trend among young people in China,     7     (offer) them an avenue to experience urban culture and local traditions.

“Kaifeng is one of China’s first national historical and cultural cities, boasting a deep-seated cultural heritage. It’s an ideal destination for unhurried exploration, encouraging visitors     8     (take) a leisurely pace as they step into Kaifeng’s embrace. The heart of Kaifeng’s cultural tourism     9     (lie) in the profound culture of the Song Dynasty (960-1279). Through cultural tourism products with different themes, including architecture, cuisine     10     opera, we aim to help visitors gain a deeper appreciation of Kaifeng’s history and heritage,” said Wei, head of the city’s cultural, radio, film and tourism bureau.
