1 . A six-year-old longing to keep a unicorn in her backyard figured she’d get the hard part out of the way first.

Last November, Madeline wrote a letter to the Los Angeles County Department of Animal Care and Control with a straightforward request. “Dear LA County, I would like your approval if I can have a unicorn in my backyard if I can find one. Please send me a letter in response.”

Director Mayeda replied two weeks later. The department does in fact license unicorns, she said, under certain conditions. Those include polishing the unicorn’s horn at least once a month with a soft cloth, feeding it watermelon at least once a week, covering it with only nontoxic and biodegradable sparkles and giving it regular access to sunlight, moonbeams and rainbows. And, because unicorns are indeed very rare to find, the department is also giving Madeline a toy unicorn to keep her company during her search, as a token of appreciation.

“It is always rewarding to hear from young people who thoughtfully consider the requirements of providing a loving home for animals,” Mayeda wrote in the letter. “I like your sense of responsible pet ownership to seek permission in advance to keep a unicorn in Los Angeles County.”

Mayeda told the Washington Post that this is the first time the department has received a request for a license for a unicorn or any mythical creature. They were impressed with the first-grader for wanting to ask permission in the first place, and doing her research to work out how to go about that. She and her colleagues deal with a lot of “life-and-death” issues on the job, whether that’s seeing cases of animal abuse or animals hurting people or making decisions about having to put down dangerous or sick animals. So Madeline’s letter has considerably brightened their spirits, and she is due to visit the department this week to discuss her unicorn license application. Safe to say, she’s in for a magical surprise.

1. Why did Madeline write the letter?

A．To apply to visit a unicorn.	B．To learn to provide animal care.
C．To ask permission to keep a pet.	D．To figure out how to find a unicorn.

2. What can we learn from paragraph 3?

A．Her application was disapproved.	B．Requirements should be met for the license.
C．She was presented with a live unicorn.	D．Guidance was given for her search.

3. Which of the following best describes Mayeda?

A．Imaginative.

B．Sensitive.

C．Flexible.

D．Convincing.

4. Why does the department think the letter “has brightened their spirits”?

A．Because it is the first application letter for a pet.

B．Because animal protection is a life-and-death issue.

C．Because they are worn out with their daily work.

D．Because they are touched with the girl’s deeds.

2 . Wild animals are equipped with a variety of techniques to avoid becoming lunch for a bigger animal, also known as a predator (捕食者) in nature. The most well-known methods include the classic fight and flight as well as freeze.

A team of researchers wondered whether closeness to people might impact those survival strategies. “We often see that animals are more tolerant around us in urban areas, but we don’t really know why.” says evolutionary biologist Dan Blumstein. “Is it individual plasticity, meaning individuals change their fear of us and that leads to tolerance? Or can there be an evolutionary factor involved?”

To find out, Blumstein and his colleagues combined information from 173 studies of over 100 species, including mammals, birds, fish and even mollusks. It turns out that regardless of evolutionary ancestry, the animals react in a similar way to life among humans: they lose their anti-predator characteristics. That pattern is especially pronounced for plant-eating animals and for social species. This behavioral change is perhaps unsurprising when it’s intentional, the result of domestication or controlled breeding. But it turns out that urbanization alone results in a similar change, though around three times more slowly.

The main point is: we’re essentially domesticating animals by urbanization. We’re selecting for the same sorts of characteristics that we would if we were actually trying to domesticate them. If the urbanization process helps animals better co-exist with people, it could be to their benefit. But if it makes them more defenseless to their nonhuman predators, it could be a real problem. Either way, these results mean that city living has enough of an influence on wild animals that evolutionary processes kick in. Those reductions in anti-predator characteristics become encoded in their genes. We’re changing the population genetics one way or another.

What the researchers now wonder is whether the mere presence of tourists in less urbanized areas can cause similar changes in wild animals. If so, serious questions exist for the idea of ethical, welfare-oriented eco-tourism. If we wish to help animals keep their anti-predator defenses, the researchers say, we might have to intentionally expose animals to predators. It’s just yet one other way that we’re changing the world around us.

1. The research led by Blumstein is aimed at ________.

A．determining how animals’ survival is impacted by individual plasticity

B．studying how living among humans affects animals’ survival strategies

C．comparing the effectiveness of different survival techniques

D．finding out which evolutionary factor impacts animals’ survival methods

2. Which of the following practices may contribute to animals losing anti-predator characteristics?

A．Controlled breeding of animals.	B．Banning the operation of eco-tourism.
C．Planned selection of favorable genes.	D．Eliminating domestication.

3. Which of the following statements is Blumstein likely to agree with?

A．Urbanization has made wild animals more alert.

B．Urbanization has brought concrete benefits to animals.

C．City living has led to animals’ genetic variations.

D．City living has helped to preserve animal species.

4. The animal rescue center spotted an injured fox a year ago and has since nursed it back to health. Before releasing it back to the wild, the center should probably ________.

A．expose the fox to the urban environment repeatedly

B．train the fox to co-exist with the less aggressive predators

C．intentionally get the fox accustomed to the presence of humans

D．purposefully adapt the fox to predator related environment

3 . On a dark night, 11-year-old Joe was playing hide-and-seek with his friends in the backyard when he thought he saw Magellan—a huge housecat. However, when the cat suddenly jumped on his head, Joe found it turned out a young cougar. He backed away from the animal, then turned and ran inside the house.

Cougar encounters like this one are becoming increasingly common in the U.S. Most people assume that’s because cougar populations are growing, or because the big cats are coming into closer contact with the expanding web of human suburbs. But Professor Robert Wielgus at Washington State University argues that poorly designed hunting policies might be causing an increase in cougar-human conflicts.

Wielgus’s research teams have been fitting the big cats with radio collars and monitoring their movements. They find that the cougar population is actually declining rapidly and almost no male cougars are over four years of age. And a study shows that the heavily hunted area has five times as many cougar complaints as the lightly hunted area—even though the density of cougars is about the same in both areas.

Wielgus suspects that hunting policies, which allow older males to be killed to keep cougar populations in check, were the culprit and teenage cougars in the heavily hunted area may be responsible for most of the trouble. To test his theory, he adds two more groups of cougars to the tracking program—one in a heavily hunted area and another in a comparable but lightly hunted area. He concludes that heavy hunting indeed almost wipes out older males and the population structure in the heavily hunted area shifts toward younger animals.

With these findings, Wielgus believes without adults to keep them under control, the disorderly teens are more likely to come into conflict with humans, farm animals and pets.

Wielgus’s ideas don’t sit well with everyone. “Hunting definitely does cause lots of teenage males to flow in, but I don’t yet see solid proof that they are more likely to cause trouble than older cats,” says the University of Montana’s Robinson. “In many cases, the new arrivals have been squeezed out of remote wilderness habitat and forced into areas where they are more likely to encounter humans. I think humans are primarily responsible for all the interaction you see. We’re moving into these areas where cougars and deer are,” according to Alldredge, a researcher at the Colorado Division of Wildlife.

We may not understand what makes 18-year-old males more likely than 48-year-old men to do dangerous things, Wielgus says, but we know that the world would be a different place, if teenagers were in charge.

4 . What do you know about fashion? The fashion industry, which has become one of the most _________ to the planet, is having a moment of punishment. But which changes make a difference, and which ones just _________ in the wash? In fact, the fashion industry is second only to the oil industry, the most environmentally unfriendly industry.

A friend of mine _________ an antique clothes store in the north of London. Business has been good for many years, which makes her acquire a large fortune. Every few weeks, she visits a vast storehouse on the edge of the city to go through piles of clothing. Most of it is _________, but if you know what you are looking for, there are raw diamonds. The storehouse has a long history. It was once a clearing house for the low-quality wool scraps(碎料) that were used to make cheap clothing for the _________ in Victorian Britain. A century on, _________ has changed. Nowadays, it is full of modern-day inferior products, all _________ cheap clothing made for the masses around the world. Except that this stuff is going to be burned or buried, not being reused.

The items are the products of an industry that, in the past 30 years, has become one of the most successful and also most _________ on the planet. Known as fast fashion, it has filled our wardrobes(衣柜) with cheap and cheerful clothes. But after three decades of continuous growth, the model is in _________ with fundamental environmental limits and there is widespread agreement – even from within the industry – that it is time to ____________. Otherwise, “Fast fashion” creates a mountain of unsellable, cheap clothing that ends up in a terrible place.

“The fashion industry represents a key environmental ____________,” says Kirsi Niinimäki at Aalto University in Espoo, Finland. “Eventually, the long-term stability of the fashion industry ____________ the total abandonment of the fast-fashion model.” Like fast food, fast fashion is all about instant ____________ on the cheap.

One wonders: What can we do about it? Don’t you have any clothes on? It’s not that ____________. More importantly, don’t waste, learn to control your desires and ____________ falling into this “Fast fashion” lifestyle. As the guardian columnist Lucy Seagal once said, the “Fast fashion” industry is profit-driven, but consumers who have experienced “over-consumption” will naturally grow tired of it, and the market will have its choice.

5 . When it comes to black holes, we are caught between a rock and a hard place. In the 1970s, Stephen Hawking showed that all black holes give off thermal radiation(热辐射)and eventually evaporate(蒸发). In doing so, they seemed to be destroying information contained in the matter that fell into them, therefore going against a rule of quantum mechanics(量子力学): information cannot be created or destroyed.

Some argued that the outgoing “Hawking radiation” preserved the information. However, if this were the case, then given certain assumptions, the event horizon(视界)—— the black hole’s boundary of no return—— would become intensely energetic, forming a firewall. But such firewalls go against the theory of general relativity, which says that space-time near the event horizon should be smooth. The black hole firewall paradox was thus born.

Now, Sean Carroll at the California Institute of Technology and his colleagues have shown that the paradox disappears when the evolution of black holes is understood in the context of the many-worlds interpretation of quantum mechanics.

The quantum state of the universe is described by something called the global wave function(全局波函数). According to traditional quantum mechanics, whenever there are many possible outcomes for physical process, this wave function ”collapses“ to represent one outcome. But in the many-worlds Interpretation, the wave function doesn’t collapse-rather, it branches, with one branch for each outcome. The branches evolve independently of each other, as separate worlds.

In this way of thinking, the formation of a black hole and its evaporation due to Hawking radiation lead to multiple branches of the wave function. An observer monitoring a black hole also splits into multiple observers, one in each branch.

The new work shows that from the perspective of an observer in a given branch, space-time behaves as described by general relativity and the black hole has no firewall.

But does that imply loss of information? No, says team member Aidan Chatwin-Davies, also of Caltech. That is because the principle of preservation of information applies to the global wave function and not to its individual branches, he says. Information is preserved across all branches of the global wave function, but not necessarily in any one branch. Given this case, a black hole that doesn’t lose information and yet has a smooth, uneventful event horizon without a fire wall isn’t a contradiction.

Yasunori Nomura at the University of California at Berkeleyy has independently arrived at some similar conclusions in his work. He agrees that the many-worlds approach resolves the paradox around information loss from black holes. “Many worlds should be taken seriously,” he says.

6 . When Mexican scientist of the evolution of animal behavior, Laura Cuaya, moved to Hungary for her postdoctoral studies in Budapest, she brought her pet dog, Kun-kun, along for the ride. Cuaya couldn't help noticing how locals warmed to dogs. This prompted her naturally curious scientific mind to start asking questions. “Here people are talking all the time to Kun-kun, but I always wonder if Kun-kun can recognize that people in Budapest speak Hungarian, not Spanish?” So she set out to find an answer through a scientific study.

Cuaya and her colleagues decided to use brain images from MRI scanning to shed light on her hunch. They worked with dogs of various ages that had, until the experiment, only heard their owners speak just one of the two languages, Spanish or Hungarian. Not surprisingly, getting the dogs to happily take part in the experiment took some creative coaxing and animal training! The researchers first needed to teach Kun-kun and her 17 fellow participating dogs including a labradoodle, a golden retriever and Australian shepherds, to lie still in a brain scanner. Their pet parents were always present, and they could leave the scanner at any point.

The research team played children's book classic The Little Prince in both Spanish and Hungarian while scanning the dogs' brains with an MRI machine. They were looking for evidence that their brains reacted differently to a familiar and unfamiliar language. The researchers also played scrambled versions of the story to find out if dogs could distinguish between speech and non-speech.

The images reveal that dogs' brains show different patterns of activity for an unfamiliar language than for a familiar one — the first time anyone has proved, researchers say, that a non-human brain can distinguish between two languages. This means that the sounds and rhythms of a familiar language are accessible to non-humans.

Interestingly, the team also found that the brains of older dogs were more skilled at detecting speech “suggesting a role for the amount of language exposure”. They suggest that dogs have refined their ability to distinguish between human languages over the long process of domestication.

1. What is paragraph 1 mainly about?

A．The background of the study.	B．The significance of the study.
C．The concern of the researcher.	D．The introduction to the researcher.

7 . Last week came solid evidence that living in toxic Britain can seriously harm your health. Cardiologists at Queen Mary University of London found that even "safe" levels of air pollution are linked to heart abnormalities similar to those seen during the early stages of heart failure. Their study of almost 4,000 people was backed up by a major US study which showed that higher exposure to fine particles and nitrogen oxides is linked to an acceleration in the hardening of the arteries (动脉).

We have long known that air pollution leads to coughing, shortness of breath and irritation in the eyes, nose and throat. It is also clearly linked to respiratory diseases such as asthma and bronchitis, as well as diabetes and some cancers. It is now beyond doubt that children's health is greatly affected, and links have been made between it and Parkinson's, Alzheimer's, dementia and congenital birth defects.

The statistics are alarming. In the UK, more than 2 million people suffer from cardiovascular (心血管的) diseases, and nearly one in seven men and one in 12 women will go on to die from them. Heart disease costs the UK economy nearly £30 bn a year to treat, as much as the state spends on secondary education. It is one of the greatest single drains on the public purse. Britain, however, rejects common sense, and shows little sign that it wants to seriously address pollution any time soon.

Despite the mounting evidence of air pollution's costs and health impact, Britain has had to be dragged screaming through the courts to make it comply with minimal clean air guidelines and laws. Successive governments have continually tried to evade their legal responsibilities, spending millions of pounds fighting in the courts and lobbying the EU to be allowed to continue to pollute.

The government now has a new draft clean air strategy our for consultation until 14 August and claims to be acting faster to tackle air pollution than almost every other major developed economy. It pledges to halve the number of people living in places that do not meet World Health Organization pollution guidelines, and it propose to end the sale of new diesel and petrol cars and vans by 2040.

But intending to cut the air pollution bill by around 12.5% in 12 years and waiting 20 years to be rid of the worst vehicles seems criminally weak. Meanwhile, government is knowingly forging ahead with infrastructure plans that will inevitably increase air pollution. The effect will inevitably be to massively increase air pollution and health costs for millions of Britons.

So could the car-clogged streets of Sunder-land, Birmingham and London, where I lived for many years, have contributed to my disease and those of millions of others? Probably. Could the oil companies be responsible for far more than climate change? Certainly. Could Britain's monstrous and mounting bill for heart disease be partly due to the highly polluting diesel cars that governments so scandalously encouraged us to drive? Quite possibly.

What is certain is that air pollution is now an international scandal, and the cause of a health emergency that governments and industry have failed to address. It undoubtedly threatens life more than any war or disaster. When there are clear alternatives to burning fossil fuels then politicians who do not act to prevent it must stand accused not just of failing to act, but of condoning the mass poisoning of their people.

1. According to the study, ________ is probably unrelated to air pollution.

A．diabetes

B．stomachaches

C．Alzheimer

D．artery hardening

2. The writer thinks Britain shows little sign to tackle air pollution because ________.

A．British government has been screaming for help in court

B．EU has dissuaded British government for help in court

C．British government has tried to have EU's permission for more pollution

D．The government firmly refused to act in accordance with the clean air guideline.

3. What is the writer's attitude toward the new draft?

A．Britain will implement it faster than other major developed economies.

B．It presents a practical way to end pollution from vehicles.

C．Its goal will be achieved at the price of massive health cost.

D．It's aiming too low when more pollution is expected.

4. What can be inferred from the article?

A．Government officials should feel disgraced for non-action as leaders.

B．The government should cover the bills for air pollution and related diseases.

C．Oil companies should not be held accountable for the international scandal.

D．British government is an irresponsible one for encouraging people to use vehicles.

8 . Brazil’s election offers hope for the rainforest

A presidential election in 2022 will offer a chance for Brazil’s government to reverse policies that have________to global climate change. The country is home to 60% of the Amazon rainforest, which has historically been an important carbon________. But a worrying study published in 2021 in Nature found that over the past decade it has________become a carbon source. The culprits: forest fires and deforestation, which has soared by more than 40% since President Jair Bolsonaro________in 2019.

On his watch, environmental enforcement and fines dropped to record lows. Activists say this has encouraged________logging, mining, and land-grabbing. In June the environment minister, Ricardo Salles, resigned after federal police began investigating him for alleged________in timber trafficking.

A greener president would try to crack down on such crimes. Polls________that Mr Bolsonaro is likely to lose the election. His successor could convince Germany and Norway to unfreeze the Amazon Fund, a pot of money for enforcement and________development that was withdrawn in 2019 amid concerns about Mr Bolsonaro’s policies. A new president could also revive talks with President Joe Biden, who has offered to________a $20bn fund for the rainforest once Brazil starts showing results.

But even an enlightened president will have to battle a________Congress, which is considering a number of laws that threaten the rainforest and its inhabitants. These include a land-regularisation bill nicknamed the “land-grabbing law” and a bill that would________wildcat mining on indigenous territories. In August thousands of indigenous people camped out in the capital as the supreme court debated a case that would restrict their territories to land that was________when a new constitution was passed in 1988. The court postponed its________, but Congress is considering a law that would have the________effect.

Better leadership in Brazil could jump-start regional efforts to boost enforcement and find sustainable________to deforestation for the rainforest’s inhabitants. But if Mr Bolsonaro wins again, his determination to fill the forest with roads, dams and mines could cause destruction far beyond the borders of Brazil.

9 . The part of the environmental movement that draws my firm’s attention is the design of buildings. Today, thousands of people come to ________ building conferences, and the idea that buildings can be good for people and the environment will be increasingly ________ in years to come. Back in 1984 we discovered that most manufactured products for decoration weren’t designed for ________ use. The “energy-efficient” sealed commercial buildings constructed after the 1970s energy crisis ________ indoor air quality problems caused by materials such as paint, wall covering and carpet. So for 20 years, we’ve been looking for ways to make these materials ________   for people and the planet.

Home builders can now use materials, such as green paints, that release significantly ________   amounts of chemical compounds, which people believe don’t ________ the quality of the air.   ________, our basic design strategy is focused not simply on being “less bad” but on creating ________ healthful materials that can be either safely returned to the soil or ________ by industry again and again. For example, the world’s largest carpet manufacturer has already ________ a carpet that is fully and safely recyclable.

Look at it this way: no one ________ to create a building that destroy the planet. But our current industrial systems are basically causing these conditions, whether we like it or not. So   ________ of simply trying to reduce the damage, we are ________ a positive approach. We’re giving people high-quality, healthful products and an opportunity to make choices that have a ________   effect on the world. It is not just the building industry, either. Entire cities are taking these environmentally positive approaches to design, planning and building.

10 . Many people learn at an early age to associate the color red with danger. So might it make sense to print medication   ________ in red ink? And since the color blue is known to call to mind the freedom of open skies, might it help artists to   ________ in a studio painted in that color? According to new research into how the brain reacts to ________ , the answer to both of these questions is yes. The study revealed that the color red seems to improve a subject’s attention to ________ , while blue appears to stimulate creativity—all without the subject realizing that his or her brain is being influenced.

“People are not ________ this effect at all,” marveled the study’s lead researcher Juliet Zhu, who studies the effects of environmental cues on behavior. To study the brain’s response to specific colors, Zhu’s team administered a series of   ________ tests to college students. For most of the tests, the students were placed in front of a computer screen that was colored either red or blue.

The researchers found that when the screen was red, subjects performed better on detail-oriented tasks. In one test,   ________ , students were asked to memorize a list of words. Zhu found that students who studied the list displayed on a red screen were able to recall more words than students who studied the list on a ________ screen.

In other tests, creative abilities seemed to be ________ by looking at the color blue. For instance, the students were asked to brainstorm potential uses for bricks. Students sitting in front of blue screens tended to come up with ideas that were   ________ , such as “make a paperweight” and “build a pet scratching post.” Students sitting in front of a red screen, on the other hand, were more likely to list ________ uses for bricks, such as “build a house.”

Researchers concluded from the tests that seeing red causes people to take the extra time to think ________ when performing detail-oriented tasks, such as ________ , proofreading— and, of course, reading those all-important warning labels. ________ most people learn early in their development that red signifies potential danger, Zhu said, seeing red perhaps helps people to slow down in order to perform at their best in a potentially risky situation. Seeing blue, on the other hand, produces images of the sky, freedom and peace. Perhaps these images, researchers supposed, ________ feelings. “It’s really this learned association with these colors that drives these different motivations,” Zhu said.
