1、Amid mounting global plastic pollution — a crisis worsened by 400 million tons of annual waste, 46% of which are single-use PET plastics — researchers have engineered PETase Plus, a bioengineered enzyme (酶) capable of degrading PET polymers (聚合物) 90% faster than natural enzymes. Published in Nature Biotechnology, this breakthrough, achieved through multinational cooperation, could redefine waste management by transforming non-recyclable plastics into reusable raw materials. Yet, its significance extends far beyond laboratories, sparking heated debates among scientists, policymakers, and environmentalists.
Unlike conventional recycling, which demands energy-intensive processes (exceeding 250℃) to melt plastics and produces useless materials, PETase Plus operates under mild conditions. By degrading PET's molecular bonds, it breaks down plastics into base components that can be re-integrated into high-quality products or even biofuels. According to Dr. Liam Harper, lead author of the study, "This method cuts energy consumption by 60% and carbon emissions by 80%, offering industries a cost-effective and eco-friendly alternative to traditional methods."
However, critics caution against unchecked optimism. While PETase Plus excels in controlled lab environments, applying it for industrial or environmental use risks unintended ecological harm. Dr. Emily Carter, a biochemist, warns, "Engineered enzymes released into landfills or oceans might also degrade natural polymers, destabilizing soil structures or marine ecosystems. Without proper restrictions, the solution to plastic waste could become an ecological disaster."
Ethical conflicts further complicate its adoption. Environmental advocates insist plastic manufacturers — responsible for 70% of global PET production — should fund large-scale application of the technology. However, industry leaders argue that governments must provide financial support to encourage innovation. Meanwhile, developing nations, where waste management system is underdeveloped, view PETase Plus as a potential lifeline, though fears spread that wealthy countries might not share the technology.
As research advances, PETase Plus is facing a challenge: a scientific success shadowed by ethical and ecological dilemmas. Its success relies not merely on biochemical efficiency but on multi-party cooperation to balance innovation with caring for our planet.
(1)、According to paragraph 2, what is one advantage of PETase Plus over traditional recycling methods?A、It produces biofuels straight from plastic waste. B、It functions effectively at relatively low temperatures. C、It removes the need for industrial funding. D、It reduces the cost by 60%.(2)、What concern do critics emphasize about PETase Plus?A、Its funding resource is still not clear. B、It may disturb natural ecosystems. C、It requires expensive lab equipment. D、Its mechanism is not yet understood.(3)、Why does the author quote Dr. Emily Carter?A、To stress the necessity for ecological regulations. B、To question the enzyme's degradation efficiency. C、To advocate for industry-led innovation. D、To highlight the technical limitations of PETase Plus.(4)、What can be a possible result of the future application of PETase Plus?A、Developing nations will reject the technology due to high costs. B、Ethical conflicts might prevent its widespread application. C、Governments will cease funding traditional recycling. D、Ecological risks will be removed. -
2、Since its announcement in 2020, Black Myth: Wukong has captured global attention, not only for its visually stunning gameplay but also for its deep cultural roots. Developed by Chinese game studio Game Science, the production is based on Journey to the West, one of China's most celebrated classical novels. The game aims to bring the legendary Monkey King, Sun Wukong, to life in a way that blends traditional Chinese mythology with modern gaming technology.
Unlike many Western fantasy games, which draw inspiration from European myths, Black Myth: Wukong presents a world filled with Chinese folk tales, Taoist philosophy, and Buddhist symbolism. The game's artistic design, from its landscapes to its supernatural creatures, reflects traditional Chinese aesthetics. Additionally, the developers have worked hard to ensure that the combat system and storytelling remain faithful to the spirit of the original novel while making them accessible to a global audience.
Despite its widespread popularity, the game has sparked discussions among different groups. Some Chinese players take immense pride in seeing their cultural heritage represented in a high-quality video game, believing it could introduce international audiences to Chinese mythology. Others, however, worry that certain adaptations may oversimplify or commercialize the story, reducing its philosophical depth to mere action and visual wonders.
Dr. Lin Zhi, a cultural analyst at Beijing University, points out: "The success of Black Myth: Wukong could mark a turning point for Chinese game developers, proving that homegrown games can compete on the world stage. However, whether it will truly deepen global appreciation for Journey to the West remains to be seen."
While debates continue, one thing is certain: Black Myth: Wukong represents more than just a game. It is an effort to reinterpret Chinese mythology for a new generation, illustrating how digital entertainment can bridge cultural divides.
(1)、What is the main purpose of Black Myth: Wukong?A、To promote Taoist philosophy to Western players. B、To combine Chinese mythology with modern gaming. C、To provide an exact retelling of Journey to the West. D、To recreate European fantasy elements in an Eastern setting.(2)、What do some Chinese players worry about?A、The game might not appeal to an international audience. B、The high difficulty level could discourage new players. C、The game's adaptation might philosophically weaken the novel's depth. D、The developers might change the main character's identity.(3)、What does Dr. Lin Zhi's statement emphasize?A、The challenges of adapting literature into video games. B、The game's impact on China's gaming industry. C、A comparison with other adaptations of Journey to the West. D、A doubt regarding the game's ability to promote a Chinese classic globally.(4)、What can we infer from the last paragraph?A、The game will likely increase international interest in Chinese games. B、There is no argument over what cultural influence the game has. C、Most players believe the game expands cultural divides. D、The game promotes China's cultural heritage among younger people. -
3、The world is emerging from the shadow of the pandemic, and I notice a curious transformation in how people approach their daily lives. The initial excitement of returning to "normal" quickly gives way to something more profound—a collective reevaluation of what truly matters.
During those long months of isolation, people developed what they thought were temporary coping mechanisms. Some planted small gardens on balconies, others mastered the art of bread-making, and many discovered the joy of daily neighborhood walks. What surprises us isn't that these activities helped through difficult times, but rather how reluctant people are to abandon them although restrictions are lifted.
My neighbor Sarah, who never showed interest in gardening before, still tends to her balcony garden even though grocery stores operate normally now. "These tomatoes aren't just about food anymore," she explains, her hands covered in soil. "Watching something grow gives you a sense of progress, of moving forward, even when everything else feels uncertain."
The most striking change is in how people value their time. Many realize that their previous definition of "being busy" often meant being disconnected-from themselves, their families, and their immediate surroundings. While video calls initially felt like a poor replacement for real interaction, they unexpectedly brought some families closer, establishing regular virtual dinner dates that continue even though travel is possible again.
Local communities strengthen in unexpected ways. The neighborhood chat groups that formed to help residents in need during lockdown evolve into active social networks. People who lived on the same street for years without speaking now organize weekly farmers' markets and community events. These connections, born from necessity, become vital threads in the fabric of daily life.
Perhaps the most significant shift is in people's approach to work-life balance. The proof that remote work is viable for many jobs leads to widespread questioning of traditional office culture. Companies that insist on returning to "business as usual" find themselves losing talents to organizations that embrace flexibility. People aren't just seeking higher salaries; they pursue arrangements that allow them to maintain the positive changes they discovered during the pandemic.
Now, as we move further from the height of the crisis, these changes become woven into the texture of our lives. The pandemic, for all its hardships, teaches us that resilience isn't just about enduring difficulties—it's about learning to flourish in new ways.
(1)、Which word can best replace the underlined word in paragraph 2?A、eager. B、motivated. C、guilty. D、unwilling.(2)、Why does the author mention Sarah's gardening experience?A、To criticize the shortage of grocery supplies during isolation. B、To show people's courage and wisdom during emergent period. C、To illustrate how temporary solutions become meaningful practices. D、To demonstrate the economic benefits of home gardening.(3)、According to the passage, which of the following statement is NOT true?A、Some activities during isolation have been kept. B、Families spend more time dining together after travel becomes possible again. C、Neighborhood bond is strengthened through community activities. D、Companies that support flexible work environment become appealing.(4)、Which is the best title for the article?A、The Unintended Legacy: How Pandemic Coping Mechanisms Redefined Modern Life. B、Beyond Survival: Reevaluation of Work-life Balance after the Pandemic. C、The Remote Revolution: Workplace Flexibility as the New Normal. D、Temporary Adaptations: The Short-Lived Impact of Lockdown Habits. -

14、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Lena had always been a quiet girl who struggled to make friends. At school, whenever someone tried to talk to her, her mind would race with worries: "What if I say something wrong? What if they think I'm strange? " These thoughts always made her stumble over her words or give awkward replies. Once, after she accidentally gave a wrong answer in class, she heard some classmates giggling (咯咯地笑). Since then, she had become even more afraid to speak up.
One rainy afternoon, while walking home from school, she noticed a small dog huddled (蜷缩) under a bush. The dog looked lost and scared, just like how she felt whenever she tried to join a conversation. It was shivering, wet, and alone. Lena crouched down and gently approached it.
The dog wagged (摇摆) its tail slightly and came closer. Lena noticed a blue collar hidden under its wet fur. Something about its trusting eyes made her heart ache. She decided to take it home. Her parents agreed to keep it temporarily while searching for its owner. Lena named the dog "Shadow" because it followed her everywhere, just like her own shadows of self-doubt.
As days passed, Lena noticed how naturally Shadow interacted with everyone. At the park, he would approach others with complete confidence and make friends effortlessly. Even when he made mistakes, like accidentally knocking over someone's water bottle, his friendly tail wag would make everyone laugh with him, not at him.
Taking Shadow for walks gave Lena unexpected friendships. Emily, a girl from her class, often came to the park with her own dog. They started talking about their pets, and soon Emily became Lena' s first real friend. Through Emily, Lena met other kids and gradually found herself part of a group that would meet at the park to play with their dogs. For the first time, she felt like she belonged.

17、This holiday, I chose to journey to the romantic city of Paris. My flight was at 6 in the morning, and I1 slept the night before. Instead, I was2 my luggage again and again, worrying about whether I had brought everything. My mom drove me to the airport at 3 am. Then, I was completely on my own. I took a deep3 to calm myself and walked into the terminal where I4 the security check without any problems.
Then I got onto the plane. When I5 the fuel of the airplane and fastened my seat belt, all of my memories of traveling came flooding back. I was no longer6. I then started figuring out how I could7 the 22 hours ahead. The seats next to me were empty, so I8 the armrest (扶手) and lay down. I now had a couch (长沙发) on the plane! I felt so9 that I slept for seven hours in total during the flight.
What about the 15 hours10? Watching some episodes would be fun. Luckily, I soon discovered a better way: onboard Wi-Fi. It was not cheap, but I would then get access to the Internet. The minute I11 into the Wi-Fi with my phone,12 started popping up. I texted back my friends, scrolled through my social media and read13 on my phone. Time passed quickly when I was lost in words. Also,14 to the internet gave me a feeling that I was still on the ground with my friends. At last, I15 the 22-hour flight, landed in Paris and started my exciting trip!

19、A puzzling primate (灵长类动物) might be the offspring (后代) of two distantly related species. And this monkey business is worrying scientists. Six years ago, tour guide Brenden Miles was traveling down the Kinabatangan River. He was on the Southeast Asian island of Borneo. Suddenly, he spotted an odd-looking primate, so he snapped a few photos. At first, he thought it could be a silvered leaf monkey with rare coloring. But then he noticed other details: The monkey's tail was thicker than it should be, and its nose was long like that of a proboscis monkey.
Scientists have now studied those photos. They suspect that this mystery monkey is a hybrid (杂交物种). Sometimes closely related species hybridize. This happens only occasionally in the wild. But what was especially surprising in this case is that the monkey's suspected parents a male proboscis monkey and a female silvered leaf monkey — are distant relatives. Scientists are concerned that this might signal that the creature's parent species are in trouble.
"Changes to the parent monkeys' habitat might explain a hybrid," said Nadine Ruppert, a primatologist who studied the mystery monkey. Oil palm plantations have been expanding along the Kinabatangan River. As forests turn to farmland, wildlife habitats can be harmed or lost. "In some spots, the suspected parent monkey species have been squeezed into small patches of forest along that river," Ruppert said. "Monkeys there could have to compete more for mates. In close quarters, the male of the bigger species can dominate. In this case, the proboscis male might easily displace males of the silvered leaf monkey."
The mystery monkey has made people living in the area very excited. "The hybrid is gorgeous, but we don't want to see more of them," Ruppert said. "Both proboscis monkeys and silvered leaf monkeys may lack enough food and space to behave as they would naturally." In Borneo and around the world, human activities and climate change are hurting animal habitats. As natural habitats are lost, mating between different species might increase.
(1)、What is the second paragraph mainly about?A、The discovery of a rare species. B、A photographer's unusual adventure. C、The new features of a strange primate. D、Differences between two monkey species.(2)、What can be inferred about the two suspected parent monkey species?A、They have to fight for oil palm fruit. B、They were previously close relatives. C、Proboscis monkeys are smaller in size. D、Shared habitats influence their interaction.(3)、What may cause hybridization according to the text?A、Natural disasters. B、Unsustainable farming. C、Extensive deforestation. D、Competitions within the species.(4)、How does Nadine Ruppert feel about the appearance of the "mystery monkey"?A、Puzzled. B、Concerned. C、Excited. D、Relieved. -
20、Your genes are inherited from parents and ancestors, picking up traits that help us survive and evolve with environments around us.
Much of this is encoded as natural instinct. When a baby is born, it needn't be taught how to breathe or cry —this is hard-wired into our DNA. We know that when tired we need to sleep and when hungry we need to eat. The same goes for animals. Within two hours of being born, a foal attempts its first steps with little guidance from its parent, all from instinct.
As well as our basic instincts, our genetics can carry more complex abilities, knowledge and reflexes. Findings have also hinted that our facial expressions could be hard-wired behaviors. Babies start to smile at around two — again, this isn't specifically taught. Although they may take in the expressions of people around, it's hard to test if they connect emotion to the faces they see. However, a 2019 study showed that athletes who had been born blind made the same disheartened expressions when losing as athletes with sight, suggesting that facial expressions may not be learnt from watching others.
While genetics play a part, infants are also heavily influenced during their time in the womb (子宫). Mothers who eat strong-tasting foods such as garlic can affect children's taste buds, giving them a fancy for the same tastes later in life. Taste and smell are important triggers that babies look for when first feeding, as the mother's milk will carry the same flavors experienced in the womb. This pre-birth taste sampling increases their chances of survival.
Generational memory could also explain why certain people are naturally gifted in areas like music or sport. Actually, the existence of it is hard to prove, since so many environmental and outside factors change behaviour and personality, especially with young minds, which are easily developed. However, the theory is starting to be taken more seriously, and studies involving short-generation life forms such as nematode worms are making significant breakthroughs. We may soon have undeniable proof that our genetics pass down more than we think.
(1)、Which of the following behavior is hard-wired into our genes?A、Learning to walk at two years old. B、Having meals due to hunger. C、Recognizing parents' voices after birth. D、Using tools to solve problems.(2)、What does the author imply in paragraph 3?A、Facial expressions may have a genetic basis. B、Babies learn facial expressions from their parents. C、Emotional responses are totally shaped by environment. D、Blind athletes can't express emotions effectively.(3)、What does paragraph 4 mainly talk about?A、The role genetics play in babies' survival. B、Significance of taste and smell in infants' growth. C、Infants' adaptability to food flavors in the womb. D、Impact of pregnant mothers' diets on babies' taste preferences.(4)、What can we know about generational memory?A、Environmental factors deny its existence. B、Promising scientific studies show its significance. C、It has been proven by existing evidence. D、It powerfully explains people's talent.
