1 . 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.

2 . 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.

3 . 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.

4 . 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.

5 . 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.

6 . An exhibition of vivid photographs and a restored documentary give fresh insight into the Antarctic explorer, who died a century ago.

One hundred years ago, the leader of the last great expedition of the heroic age of polar exploration died from a heart attack as his ship, Quest, headed for Antarctica. The announcement of the death of Ernest Shackleton on 30 January 1922 was greeted with an outpouring of national grief.

This was the man, after all, who had saved the entire crew of his ship Endurance — which had been crushed and sunk by ice in 1915 — by making a daring trip in a tiny open boat over 750 miles of polar sea to raise the alarm at a whaling station in South Georgia.

It remains one of the greatest rescue stories of modern history and led to the idolising of Shackleton in the United Kingdom, a reputation that survived undamaged for the rest of the century. As his contemporary Raymond Priestley, the geologist and Antarctic explorer, later put it: “When disaster strikes and all hope is gone, get down on your knees and pray for Shackleton.”

And here and now in 2022, his death is being marked with an elaborately illustrated exhibition — Shackleton’s legacy and the power of early Antarctic photography — which opens at the Royal Geographical Society (RGS), and which includes a range of images and artefacts from his expeditions. Additionally, a digitally remade version of South, a documentary film of Shackleton’s 1914-16 Endurance expedition, is being screened at the British Film Institute.

The film and most of the exhibition’s finest images are the handiwork of Frank Hurley, who sailed with Shackleton and who was one of the 20th century’s greatest photographers and film-makers. Both film and exhibition feature striking camera work and provide vivid accounts of the hardships that Shackleton and his men endured as they headed off to explore Antarctica.

Even after he survived the great expedition, he still longed for another trip to Antarctica, and after long negotiations set sail in Quest, from England, with the aim of circumnavigating (环航) Antarctica, Shackleton was by now very ill and had suffered at least one heart attack. On 2 January 1922, he wrote in his diary: “I grow old and tired but must always lead on.” Three days later he had a major heart attack and died a few hours later. He is buried on South Georgia, scene of his greatest triumph.

“Shackleton was an inspirational leader. He had an innate sense of what was possible and achievable. He also had a huge personality but led by example. At the same time, he was sensitive to the needs of the individuals he was leading. For example, after Endurance broke up, his men had lost their protection and shelter. Their social fabric had been destroyed. There would have been disagreement. Yet Shackleton succeeded in keeping them together and made sure they survived.”

1. People were overcome with grief when Ernest Shackleton died because          .

A．it was a huge pity that such a brave explorer should have died from a heart attack

B．he was the man that wrote about one of the greatest rescue stories of modern history

C．he came to his entire crew’s rescue and symbolised hope in extreme circumstances

D．It is created by Frank Hurley, who witnessed Shackleton’s heroic acts with his own eyes.

3. Which of the following is NOT true about Ernest Shackleton according to the passage?

A．He was the leader of a heroic exploration to the South pole, who died from a heart attack off shore.

B．He saved the crew members of the sunken Endurance by travelling to raise the alarm in a tiny boat.

C．He is universally recognised as the greatest Antarctic explorer who has enjoyed enduring fame.

D．He was inspirational, practical, responsible, sensitive towards his men, but had a strong character.

4. What does “Their social fabric had been destroyed. ” in the last paragraph most probably mean?

A．What they wore would not be accepted by others upon returning.

B．They could no longer socialise with others even if they went back.

C．The ship could not keep them together even if they survived.

D．They could not function socially as they had when there was shelter.

7 . AI-based Conservation Efforts

When an endangered seabird hits a power line, it makes a sound “very much like the laser sound from Star Wars,” says conservation (野生动物保护) biologist Marc Travers. He should _________ as his team from the Endangered Seabird Recovery Project recorded thousands of hours of audio to determine if power lines affected local seabirds. Travers was trying to help establish how _________ birds were killed by power lines on the island of Kauai in Hawaii in 2011.

His team recorded 600 hours of audio and sent the recordings to Conservation Metrics, a company that assists conservation efforts with AI resources. Conservation Metrics used a program to “listen” to the recordings and _________ the sounds that signified bird electrocutions (触电身亡) . The result was _________, as the number of bird electrocutions was in the thousands. Armed with _________ that power lines were killing a significant number of birds, the team worked with the local utility service to reduce bird deaths.

_________, humans have been poor guardians of the planet. Humans have altered as much as 97 percent of land ecosystems. Key populations of _________ animals have dropped as much as 68 percent since 1970. The _________ in biodiversity around the world has created a depressing situation. Conservation efforts _________ key resources they need to have real impacts.

__________, humans now have AI-based tools that can help. AI can quickly and accurately __________ large amounts of data created by observations in the field. Then other programs such as PAWS (Protection Assistant for Wildlife Security) can help analyze the data and suggest the most __________ ways to focus conservation efforts.

In large national parks and wildlife reserves, poachers (偷猎者) are a danger for animals both big and small. Some animals are worth a lot of money on the black market. Park guards are left with an impossible task because there is too much land to __________. But the PAWS program allows guards to focus their efforts. PAWS has even predicted the __________ of traps in areas not yet patrolled (巡逻) by rangers!

We still face many challenges to __________ the loss of wildlife, but AI-powered programs promise to be a powerful conservation tool.

8 . In 2004, Pen Hadow became the first person to trek (跋涉) to the North Pole alone, without being resupplied on the way. That meant swimming through unimaginably cold waters, and risking encounters with polar bears. Just eight months later, he made a similar trip to the South Pole. Now he is back in the Arctic again, preparing for an expedition (远征) he says is even more ambitious. Explorers are confident, driven individuals. They have to be. This time, however, more significance is attached. Pen and two colleagues will set out on a three-month, 1000-kilometre trek to the North Pole, taking detailed measurements of the thickness and density of the ice. Nobody has ever done this before, and he knows the results will be of vital significance to the scientific community. This will be the truest picture yet of what global warming is doing to the ice that covers the polar region.

Pen and his wife, Mary, live in the country with their two children. “It’s much harder to be away from them this time,” he admits. They were one and five when I last went, and I made a mistake in the way I said goodbye. I thought it would be a good idea to say to my son, “You’re the man of the house now, look after your mum and your sister.” He absolutely took it to heart, asking his mum how she was all the time, but the stress eventually became too much. While it was well intentioned, it was an unfair thing to do.

He is spending these last days before departure preparing his things. “Out on the ice, one is virtually unable to mend things or do anything that isn’t absolutely straightforward,” he says. With him will be Ann Daniels, one of the world’s leading polar explorers, and the photographer, Martin Hartley. They will be supported by a crew of six, flying in supplies. Being part of a team is actually more stressful to someone with his mentality, says Pen, and something else is on his mind too. “I’m going to be 47 on Thursday. I’ve done far less training than I’m comfortable with.” Why? “Organisational things always seem more urgent. So I’m almost fearful of what I’m going to ask of myself.”

Pen believes his mission reconnects exploration with the search for knowledge that drove previous generations into the unknown. “Making it to the North Pole was a personal ambition,’”he admits, “and of limited value to anyone beyond the polar adventuring community. This time, scientists will profit from the data, and we’re creating a platform in which to engage as many people as possible in what’s happening in the Arctic Ocean. This is important work, and nobody can do it but us,” he says. “Our skills, which are otherwise not that necessary, have become really relevant. Suddenly, we’re socially useful again.”

1. In the first paragraph, what do we learn about Pen Hadow’s opinion of the new expedition?

A．He feels certain that it will be stressful.

B．He is aware of the huge importance of its aims.

C．He thinks it may be harder than his previous journeys.

D．He is less than confident of the scientific work it involves.

2. What does “took it to heart” (in paragraph 2) mean?

A．He started to feel unwell.	B．He memorised his father’s words.
C．He was afraid of the responsibility.	D．He carried out his father’s words carefully.

3. What is worrying Pen about the new expedition?

A．Whether he will be mentally prepared

B．Whether he will still be fit enough to take part.

C．Whether the arrangements he has made will turn out well.

D．Whether the equipment will work properly in icy conditions.

4. When he compares the new expedition to his previous ones, Pen feels ________.

A．uncertain if it will collect information.

B．doubtful about its long-term usefulness

C．pleased that more people will benefit from it

D．relieved that the general public will be more supportive

Owning a Pet Is Good for Your Health

Pets in America are incredibly well loved: according to a 2015 Harris poll, 95% of owners think of their animal as a member of the family. About half buy     1     birthday presents. And it’s a two-way street. People who have pets tend to have lower blood pressure, heart rate and heart-disease risk than those who don’t. Those health benefits may come from the extra exercise that playing and walking     2     (require), and the stress relief of having a steady best friend on hand.

Scientists are now digging up evidence     3     animals can also help improve mental health, even for people with challenging disorders. Small     4     the studies are, the benefits are impressive enough that clinical settings are opening their doors to animal assisted interventions — pet therapy, in other words — used alongside conventional medicine. “    5     (think) of an animal in a hospital used to be one of the great no-no’s,” says Alan Beck, director of the Center for the Human-Animal Bond at Purdue University, citing the fear of causing infection. “Now, I don’t know of any major children’s hospital     6     at least some kind of animal program.”

The rise of animal therapy     7     (back) by increasingly serious science showing that social support — a proven antidote to anxiety and loneliness — can come on four legs, not just two. Animals of many types can help calm stress, fear and anxiety in young children, the elderly and everyone in between.

More research is needed     8     scientists know exactly why it works and how much animal interaction is needed for the best results. But     9     (publish) studies show that paws have a place in medicine and in mental well-being. “The data is strong,” Beck says. “If you look at     10     animals do for people and how we interact with them, it’s not surprising at all.”

Venice—The Risk of the Disappearance of an Entire City

Venice is a stunning oddity. It is a city built atop around 120 islands, crisscrossed by 177 canals, and is best explored via the use of its 391 bridges. But the city is not well recently. Indeed,     1     drastic measures are taken, the city’s days could be numbered.

This is far from hyperbole(夸张): Venice is at very real risk of     2     (consume) by the sea. In worst-case scenario, the city could disappear beneath the waves by 2100. Meanwhile, many of its building are sinking     3     being damaged by the wakes of boats. It is also routinely overwhelmed by tourists, while its local population is in continual decline.

Globally, a lot of cities    4     (hit) by similar problems of sinking land and rising sea levels in Venice. Low-lying Jakarta(雅加达), for example, is in such a terrible situation that it is being replaced     5     the capital city of Indonesia by Nusantara, a city not yet even built.

In November 2019, Venice suffered its second-worst flooding. It created headlines around the world, with onlookers     6     (astonish) by the incredible images of Saint Mark’s Square, one of the city’s lowest lying areas, covered in feet of water.

The tide reached a peak height of 187cm above sea level,     7     (result) in more than 80% of the city being under water. A state of emergency was declared, and there was an estimated €1bn euros worth of damage.

The worst ever flooding event, which happened in 1966,     8     (see) water levels rise to 194cm above sea level, and is thought     9     (damage) at least three quarters of the city’s shops, businesses and studios.

    10     a gap of over 50 years separated these events, recent trends suggest that we won’t have to wait half a century to see another disastrous flood. Since water levels started being officially recorded in 1923, they have reached 150cm or more on only 10 occasions, but five of those have been in the last three years.
