1 . More than one-third of the world’s food is wasted or thrown away, most of which ends up in landfills, producing very large amounts of planet-warming greenhouse gases. Now, many studies show that it is becoming harder to grow enough food to feed an increasing population due to climate change and soil degradation.
But one of the most promising and simplest solutions lies in the problem itself: this wasted food — if composted (堆肥) — could slow climate change and improve soil quality. Higher-quality soil also continues to absorb more carbon from the atmosphere, helping to improve plants and contributing further to fighting climate change. Returning one ton of organic matter to each hectare of soil would increase the production of cereal crops each year in Africa, Asia and South America by millions of tons.
While it is true that people can compost in their yards, community gardens, or even on their kitchen counters, larger-scale efforts, including infrastructure (基础设施) and incentives (激励) for consumers, would take it to the next level. Imagine if consumers could just leave unwanted food in a roadside bin for pickup, or drop it off at a local store, earning a few cents a bucket, just like what has been offered for recycling bottles or newspapers.
Moreover, in the case of composting, the payment incentive system would be sustainable because the end-product of compost can be sold to farmers, making it an economically workable model, something that is often lacking in recycling, especially for certain materials, like many types of plastics.
Eventually, more widespread composting of food would pave the way for solutions to additional waste challenges, such as the disposal of packaging and clothing. This will have other positive effects as well; if more consumers compost, companies will be more inspired to make and use compostable packaging, clothing, and other products. While more compostable items are starting to emerge today, additional composting will further drive demand and innovation, and offer a game-changing solution for the planet.

2 . The similarities between elephant and human behaviour have been a curiosity to scientists worldwide. These huge beasts are not so different from us. Their devotion to their family is just as powerful as the friendships between humans. In order to prevent future elephant attacks, people must first understand the similarities between elephants and themselves.
Because deaths are felt so deeply in elephants, memories of people harming or killing elephants are not forgotten. Due to the UgandaTanzania War in Africa, poaching (偷猎) elephants increased during the 1970’s and continued, despite government restrictions. However, ecologists like Eve Abe did not see this as simple poaching; they saw it as a “mass destruction”. Elephants that have witnessed the murder of a matriarch, are more likely to become violent and attack humans. Many aggressive elephants do not act without reasons; they are suffering from Post Traumatic Stress Disorder (PTSD). At their young age, humans invaded their life, killed their parents, and ultimately destroyed their peaceful environment. More and more calves live neglected lives without a mother figure, and have to become a parent early for survival. Humans that have a difficult childhood or early family life also suffer from aggression and pain. Young elephants have been known to have “nightmares”, waking up suddenly and screaming. These are clearly signs of stress, as males grow up to be increasingly hostile (敌对的) to humans and target certain villages where painful experiences have occurred.
Although many see elephants as massive, violent, and simpleminded animals, their social structure is not unlike many human societies. Humans and elephants have been on parallel paths. However, if people continue practising ignorance over the cruel treatment of these creatures, then collision will become inevitable.
Cruel treatment of elephants still goes on, but by understanding the similarities between us, it can be stopped.

3 . Marine life (海洋生物) in Florida Keys is negatively influenced by two forces: human activity and climate change. The former involves fishing, tourism and diving while the latter causes a large increase in intense hurricanes. Fortunately, when the researchers of Florida Museum of Natural History started looking for sea urchins (海胆) on the ocean floor off the coast of Florida Keys in the summer of 2020, they uncovered their population had relatively been stable since the 1960s.
The researchers visited 27 sites along a 20-mile stretch of coast near Florida Keys looking for tracks that reflected the presence of burrowing echinoids (穴居海胆类动物).“The findings that burrowing echinoids have been highly resilient (有适应力的) against climate change and environmental pollution over the last 60 years was a huge discovery for us.” said study co-author Tobias Grun.
Grun said, “However, we know little about their current distribution, population size, and health. The reason is not the lack of interest by the scientific community but lies in that fieldwork is very expensive.” As the climate crisis progresses, it’s important to understand why some marine creatures are more resilient in bearing the impacts of a worsening environment than others. Grun said, “Evolution may be at play. Some marine animals are very opportunistic. They can tolerate a wide range of abiotic factors like pH, temperature, and salinity, to name a few.”
Grun added, “At this point, our data show that burrowing echinoids are more resilient than many other marine species and are doing comparatively well. That does not mean that we can push our luck and keep going the way we are right now. Our study provides some hope that these creatures are resilient, but much more work is needed to translate our findings into a larger scale. The reasons for their resilience are also widely unknown.”

4 . High in the Swiss Alps and the Arctic, scientists have discovered microbes (微生物) that can digest plastics — importantly, without the need to apply extra heat. Their findings, published in the journal Frontiers in Microbiology, could one day improve plastic recycling.
It’s no secret that plastic pollution is still a big, global issue. Since its production exploded during and after World War II, humans have created more than 9.1 billion tons of plastic — and researchers estimate that less than one tenth of the resulting waste has been recycled. To make matters worse, the most common recycling option — when plastic is washed, processed and turned into new products — doesn’t actually reduce waste: The recycled materials are often of lower quality and might later end up in a landfill all the same.
So, researchers are looking for solutions to the plastics problem that go beyond conventional recycling — and one process they’ve experimented with is breaking down plastics using microbes. But the known plastic-digesting microbes can only do so at warm temperatures above 85 degrees Fahrenheit. When done at an industrial scale, the amount of energy needed to generate that much heat makes the process give off more carbon —and cost more money.
But the microbes found in the Arctic and Swiss Alps can function at cooler temperatures: They were able to break down biodegradable (可生物降解的) plastics at 59 degrees Fahrenheit. In the new study, co-author Joel Rüthi and his colleagues discovered that of the total 34 types of microbes examined,19 were successfully able to break down a form of plastic called polyester-polyurethane, and 17 could break down two types of biodegradable plastic mixtures.
Unfortunately, the plastics that the microbes partially degraded represent a “really small amount of plastics in circulation,” said Gavin Lear, an environmental microbiologist, who was not involved in the study. Lear acknowledged that using natural microbes can provide a head start when it comes to designing a strategy for bio-recycling. If we move away from the conventional non-biodegradable materials, “and we start to use more of these biodegradable plastics, then it’s good that we know how to degrade them more quickly so they’re less of an environmental problem,” he concluded.

5 . “From one day to the next, our profession was wiped out. We woke up and discovered our skills were unnecessary.” This is what two successful graphic designers told me about the impact of AI. The old promise—creative workers would be better protected than others from mechanization (机械化) —ruined overnight. If visual artists can be replaced by machines, who is safe?
While there’s plenty of talk about how education might change, little has been done to equip students for a world whose conditions shift so fast. It’s not just at work that young people will confront sudden changes of state. They are also likely to witness more environmental breakdown and the collapse of certain human-made systems.
Why are we so unprepared? Why do we manage our lives so badly? Why are we so expert at material innovation, but so unskilled at creating a society in which everyone can succeed? Why do obvious lies spread like wildfire? What is lacking in our education that leaves such gap s in our lives?
The word education partly comes from Latin, meaning “to lead out”. Too often it leads us in: into old ways of thinking, into dying professions. Too seldom does it lead us out of our cognitive and emotional circles, out of a political and economic system that’s killing us.
I don’t claim to have definitive answers. But I believe the extreme demands, throughout our schooling, of tests and exams reduce the range of our thinking. The exam system creates artificial borders. The intense combined demands of the testing system leave almost no time to respond to opportunities and events, or for children to develop their own interests.
Education should be joyful and delightful, not only because joy and delight are essential to our health and happiness, but also because we are more likely to survive major changes. Schooling alone will not be enough to lead us out of the many crises and disasters we now face. But it should at least lend us a torch.

6 . A community canteen at the Zhanongkou Community in Shangcheng, Hangzhou recently launched “happiness blind boxes”, which cost just 6 yuan per box. Sales start at 7 p. m. each evening.
The dishes are packaged in transparent (透明的) containers, but to maintain an element of surprise, stickers are placed over the lid (盖子) of the “main dish” section of each box. The “blind boxes” have become popular since being introduced, and on some nights they sell out by about 8 p. m.
A meal assistance program introduced in Zhanongkou subdistrict ensures the elderly can access meals within a 10-minute walk of their homes or have them delivered within five minutes. The service has also been welcomed by younger people living and working in the area.
Yan Xuyang, a professor at Beijing Union University’s Tourism College, predicts that by 2035, those born from the 1970s to the 2000s will comprise the main group of customers for such canteens. “This generation has a reasonable level of disposable (可自由支配的) income, and many of its members may also lack the willingness to prepare meals for themselves,” Yan said.
The successful operation of community canteens depends on their ability to integrate into the daily lives and culture of local residents. In addition to serving dishes to suit local tastes and fostering a welcoming environment for diners, it is important to widen the functions of these canteens. They have been used for cultural activities and other events, which helps raise awareness and foster a positive perspective on these canteens among local communities.
In the latter part of last year, the Weikang community canteen in Ziyang subdistrict, Hangzhou, experienced a significant transformation from being a canteen for seniors to catering for the whole community. Its services have been broadened beyond regular operations to include services for hospitals and businesses, complete with home delivery options. Some other community canteens have also made efforts to appeal to more residents.
1. What can we know about the “happiness blind boxes” from the passage?| A．They are sold out every night before 8 p. m. |

| D．To show the innovative reform of community canteens. |
7 . The behavior of beavers and other animals has often inspired expressions in English. If someone is very industrious or hard-working in tackling many things at once, we can say the person is “as busy as a beaver.” This phrase hints at one of the characteristics of these wild animals—they are indeed active creatures.
With their large teeth, which are orange due to iron in the tooth enamel (牙齿的珐琅质), beavers can cut down trees and change their environments like no other animals except humans. They use these fallen trees to build dams, creating safe, watery environments. The busy beavers build homes — called lodges — in the ponds created by the dams. The only way to get in and out of lodges is by entering an underwater opening of the structures. This offers beavers protection from predators such as bears, wolves, or coyotes.
It’s also interesting to note that beavers have another reason for cutting down trees aside from building dams. Beavers can digest cellulose, so wood is a significant food source for them, with their diet 15 also consisting of leaves and aquatic plants. Chewing on trees also helps beavers keep their teeth sharp, making it easier for them to keep chopping down trees.
Of course, no discussion about beavers would be complete without mentioning their most noticeable feature their large, flat tails, which have different uses. One is that they act as a rudder, helping them steer in the water. Another is that the animals pound their tails on the water to warn other beavers of danger. Since beavers work so hard building their homes and warning others of potential harm, it’s no surprise that busy as a beaver is a common phrase.
1. Which of the following usages of “as busy as a beaver” correct?| A．My cat is as busy as a beaver since it always lies on the sofa. |
| B．This kind of tree is as busy as a beaver because it takes hundreds of years for it to be used as timber. |
| C．Hanna is having a cup of coffee and listening to music in the living room. She is truly as busy as a beaver. |
| D．Oliver is responsible for two projects and has to train the three new employees, so he has been as busy as a beaver recently. |

| C．The animals that threaten beavers. | D．The food that beavers eat. |
| A．The wood is very strong. |
| B．The water from dams helps beavers digest wood. |
| C．Dams make it harder for other animals to catch. |
| D．Dams provide beavers with lots of water to drink. |
| A．Tail | B．Teeth | C．Paw | D．Head |
8 . The growth mindset is the belief that intellectual abilities can be developed and are not fixed, which have received a great deal of attention in schools and among researchers.
According to a study, a teacher’s growth mindset acts as a “support” that can draw out a student's growth mindset at the very beginning and make it maintainable and actionable in the classroom. These teachers may convey how, in their classes, mistakes are learning opportunities, not signs of low ability, and back up this view with assignments and evaluations that reward continual improvement. This could encourage a student to continue acting on their growth mindset.
The study analyzed data from the National Study of Learning Mindset, which was an intervention experiment conducted with a sample of ninth-grade students’ math grades. The present focus on math grades is motivated by the fact that students tend to find math challenging and anxiety inducing, and therefore, a growth mindset might help students face those challenges productively.
In the study, researchers show that the positive effect of a short growth-mindset intervention on ninth-grade students’ math grades was concentrated among students whose teachers themselves had growth mindset. They also found that baseline students — serve as a benchmark (基准点) for comparing and evaluating the progress of other students — who reported more fixed mindset in classrooms showed a significantly positive effect on math grades.
Successfully teaching a growth mindset to students lifted math grades overall, but this was not enough for all students to reap the benefits of a growth-mindset intervention. Supportive classroom contexts also mattered.Students who were in classrooms with teachers who approved of more of a fixed mindset did not show gains in their math grades over ninth grade, whereas the same kind of students in classrooms with more growth-mind set teachers showed meaningful gains.
In general, they view the testing and understanding of the causal effect of teacher mindset as the next step for mindset science. Such research will be challenging to carry out, however.

9 . Recently, I accidentally found a set of Hanfu l only wore once from the bottom of the cupboard. I remember buying them simply to match the ancient-style hair accessories (配饰) a friend gave me. It occurred to me that 1 had been trapped in the “birdcage effect”.
“Birdcage effect” means that when you get an item one day, you will prepare more things to match it. Weeks ago, I was in the company of friends engaged in shopping. One said that she wanted to buy a good writing pen to match the delicate notebook that her sister gave her, so that she would fall in love with taking notes on reading, and thus love reading, not just reading. I joked that she must have fallen for the “birdcage effect”. But the friend said with a smile: “Why not use the ‘birdcage effect’ instead?”
For the first time, I heard that the “birdcage effect” can be used in reverse (逆向). However, this can’t help but remind me of middle school, and I seem to have used the “birdcage effect”. Passing by a bookstore one day, I purchased a magazine and saw the call for contributions published in the magazine, so I started writing with eager hands, and then I fell in love with writing.
After shopping with my friends that time, I began to proceed to use the “birdcage effect”. I bought a small fresh tablecloth to decorate my desk, and a beautiful notebook to record my inspiration. When everything was ready, I started writing again.
But how can we get rid of the “birdcage effect” in many things, and even use the “birdcage effect” in the opposite way? Various “birdcages” unavoidably appear in life, but we can distinguish them. If it is not in line with the actual situation, it is a “negative birdcage”, then we must learn to stop losses in time and maintain a heart of abandonment and separation. If it is a “positive birdcage” that motivates us to develop upward, we can clarify our goals, shop or decorate appropriately, and motivate ourselves to move towards our goals. At this time, you will find that the “birdcage effect” is actually not so terrible!

10 . Over 7,000 species around the world are considered endangered. That number doesn’t even include the plants, animals, and other lifeforms that are listed by some scientists as vulnerable, critically endangered, or extinct in the wild.
The International Union for Conservation of Nature (IUCN) maintains the most-comprehensive list of endangered species around the world. The Red List of Threatened Species, as it’s called, judges each species on five different standards for an in-depth scientific approach. According to the IUCN, an endangered species is one that meets any one of the following criteria (标准): a 50%-70% population decrease over 10 years, a total geographic area less than 5,000 square kilometers, a population size less than 2,500 adults, a restricted population of 250 adults, or a statistical prediction that it will go extinct within the next 20 years.
Though the IUCN’s Red List covers a wide range of what qualifies as an endangered species, it doesn’t quite say how a species reaches those low points. Prepare to feel guilty: the most common factor when it comes to species decline is human intervention. Loss of habitat, the introduction of a foreign species into the environment, hunting, pollution, disease, and loss of genetic variation (基因变异) are all causes of species decline and most often are a result of human activities. Take the bald eagle for example: the rise in human population and urban development of North America limited the animal’s habitat; an increase in hunting the eagles for sport lowered their population size; and the use of the pesticide DDT on farms harmed the animal’s reproductive capabilities.
But even though humans are the number one cause of species decline, classifying species as endangered encourages action to reverse the effects of human intervention. Conservation efforts by the US Fish and Wildlife Service criminalized (使非法) the hunting of bald eagles and the use of the pesticide DDT in the mid- to late 20th century. The effect was positive, as bald eagles have been on the rise and were taken off the endangered species list in 1995.
