1 . As more and more people speak the global language of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will be likely to die out by the next century, according the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations — UNESCO and National Geographic among them — have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following in that tradition. His recently published book, A Grammar of Thangmi and Their Culture, grows out of his experience living, working, and raising a family in a village in Nepal.
Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials —including photographs, films, tape recordings, and field notes — which had remained unstudied and were badly in need of care and protection. Now, through the two organizations that he has founded — the Digital Himalaya Project and the World Oral Literature Project — Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to schools but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

2 . Humans’ overconsumption of resources is a leading contributor to global climate change, says University of Arizona researcher Sabrina Helm. Therefore, it’s increasingly important to understand the choices consumers make and how those decisions affect the health of a planet with limited resources. In a new study, published in the journal Young Consumers, Helm and her colleagues explore how materialistic values influence pro-environmental behaviors in millennials, who are now the nation’s most influential group of consumers.
The researchers focused on two main categories of pro-environmental behaviors: reduced consumption, which includes actions like repairing instead of replacing older items; and “green buying,” or purchasing products designed to limit environmental impacts. The researchers also looked at how engaging in pro-environmental behaviors affects consumer well-being.
More materialistic participants, the researchers found, were unlikely to engage in reduced consumption. However, materialism did not seem to have an effect on their likelihood of practicing “green buying.” That’s probably because “green buying,” unlike reduced consumption, still offers a way for materialists to fulfill their desire to get new items, Helm said.
Study participants who reported having fewer materialistic values were much more likely to engage in reduced consumption. Consuming less was, in turn, linked to higher personal well-being and lower psychological suffering. Green buying—which may have some positive environmental effects, although to a smaller degree than reduced consumption—was not found to improve consumer well-being, Helm said.
The take-home message for consumers: “The key is to reduce consumption and not just buy green stuff. Having less and buying less can actually make us more satisfied and happier,” Helm said. “If you have a lot of stuff, you have a lot on your mind,” she said. “For example, it requires maintenance and there’s a lot of burdens of ownership, and if you relieve yourself of that burden of ownership, most people report feeling a lot better and freer.”
Helm and her colleagues additionally looked at how materialism affects millennial consumers’ proactive financial behaviors, such as budgeting and saving. Examining financial behaviors alongside pro-environmental behaviors provides a picture of how young adults proactively deal with resource limitations in two contexts: environmental and financial, Helm said.
As expected, Helm and her colleagues found that those who reported having more materialistic values engaged in fewer proactive financial behaviors than their less materialistic counterparts (对应的人). The researchers also found that, consistent with previous studies, proactive financial behaviors were associated with better personal well-being, life satisfaction and financial satisfaction, as well as lower psychological suffering.
Understanding how materialistic values impact consumer behaviors, and how those behaviors in turn affect personal and environmental well-being, is important, Helm said. However, she acknowledges that for many consumers, shifting behaviors to be more financially proactive and consume less will be challenging.

3 . Blood-Doping Champion
Blood doping (违规输血) to improve performance is forbidden in professional sports. Athletes can use this technique to fuel their muscles with more oxygen-carrying red blood cells—for example, by receiving a transfusion. But many animals dope naturally: sheep, fishes and horses can boost their blood’s capacity to carry oxygen by 16 to 74 percent in physically demanding situations. Now a study shows that an Antarctic fish called the bald notothen can increase its carrying capacity by more than 200 percent to pursue an active life in cold waters.
Like most fishes native to Antarctica, the bald notothen’s blood contains anti-freeze proteins that help it withstand extreme cold. But these proteins, along with red blood cells (RBCs), can make blood sticky and hard to circulate. Some Antarctic fishes adapt by removing RBCs altogether, absorbing oxygen directly from the water via skin as they passively await prey (猎物). Bald notothens, however, actively swim below surface ice to chase other active life when avoiding seals and penguins. For this behavior, “you need to supply more oxygen to the muscles,” says Michael Axelsson, a physiologist at the University of Gothenburg in Sweden and co-author of the new study.
The scientists compared RBC levels in samples collected from bald notothens relaxing in glass tanks with those in samples drawn from fish they “chased” using a plastic tube. RBC levels were at 9 percent in the resting animals but 27 percent in the exercised ones, showing a 207 percent increase in the latter’s blood oxygen carrying capacity. “No other fish we’ve seen can more than double their RBCs or drop their numbers to such a low level when resting,” Axelsson says. The fish’s spleen (脾) stores RBCs, and the researcher found that to release more into the bloodstream, the organ shrinks to weigh 41 percent less.
The enormous changes in RBC levels initially surprised Gerald Kooyman, a biologist at the Scripps Institution of Oceanography, who was not involved in the study. He notes, however, that these animals have fewer blood cells to begin with, so maintaining circulation with a tripled RBC count is less difficult. If a diving Weddell seal pushed its RBC levels from 40 to 90 percent, for instance, its blood would be dangerously hard to pump.
Yet bald notothens do face trade-offs for their ability. The scientists found blood pressure was 12 percent higher and the heart worked 30 percent harder in active individuals. Bald notothens can rest during quiet times, but when they need to use their abilities, Axelsson says, “these fish have to live with more RBCs because they need more oxygen.”

4 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.

5 . Bird pattern carved on Yubi in Chinese, comes alive and circles around, while an audio guide introduces the cultural relic and the bird’s connotation (寓意). Such is the experience of watching a cultural relic through a pair of augmented reality (AR) glasses at the Liangzhu Museum.
The museum displays various burial objects found in the Archaeological Ruins of Liangzhu City in Hangzhou, showcasing the civilization of prehistoric rice agriculture and a state-level society between 3,300 B.C. and 2,300 B.C. The site was included on the UNESCO World Heritage List in July 2019, providing profound and compelling evidence that Chinese civilization started 5,000 years ago.
Using AR to tell Liangzhu’s ancient story and let the young people sense and feel close to cultural relics through modern technology is an important task at the museum, making it a pioneer in using modern technology and a hot place for tourists.
“I found that most students were very curious about it, and it could inspire students to have the desire to learn more,” said Chen Xi, the AR glasses provider. “I’ve never seen this before. The illustration of the ancient wild birds above is not that clear. But with the AR glasses, I know what the ancient wild bird exactly looks like and how it is different from what we see on TV,” said Rong Mei, a visitor in her twenties. “Compared with traditional ways of appreciating a cultural relic, AR glasses guide has virtual images which help people visually understand the information behind the relic, such as in which life scenarios was the relic used, its function and its cultural connotation,” said Zhou Liming, director of the Liangzhu Museum.
From digitalization to intelligentization (智能化), the Liangzhu Museum took more than five years. It started to collect the digital information of the ruins and relics since 2015. It paves the way for the museum to deliver Liangzhu’s story through multimedia approaches to attract more people, especially the youth, as modern technology bridges the gap between young people and cultural relics.

6 . You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place.“They” did things to you which caused all of your pain and suffering.“They” are wrong and bad, and life is terrible as long as “they” are around.Or you may blame yourself for all your problems, thus internalizing(内化)your victimization.The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.
Those who choose to be creators look at life quite differently.They know there are individuals who might like to control their lives, but they don't let this get in the way.They know they have their weaknesses, yet they don't blame themselves when they fail.Whatever happens, they have choice in the matter.They believe their dance with each sacred(神圣的)moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart.Victims relish(沉溺)in anger, guilt, and other emotions that cause others--and even themselves---to feel like victims, too.Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but al1around them.Both victims and creators always have choice to determine the direction of their lives.
In reality, all of us play the victim or the creator at various points in our lives.One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime.Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.
1. What does the word “they” in Paragraph 1 probably refer to?| A．People and things around you. | B．Opportunities and problems. |
| C．Creators and their choices. | D．Victims and their sufferings. |
| A．seem willing to experience failures in life | B．possess the ability to predict future life |
| C．handle ups and downs of life wisely | D．have potential to create something new |
| A．To define victims and creators. |
| B．To evaluate victims against creators. |
| C．To explain the relationship between victims and creators. |
| D．To suggest the transformation from victims to creators. |
| A．strong attachment to sufferings in life pulls people into victims. |
| B．people need family support to deal with challengers in life. |
| C．it takes creators quite a long time to get rid of their pains. |
| D．one's experiences determine his attitude toward life. |
7 . The twilight zone (朦胧地带) contains the largest and least explored fish stocks (储备) of the world’s oceans. Ranging from just below 200 metres to 1,000 metres deep, it is an interface between the well-studied sea life in the sunlit zone above and the ecosystems of the darkest territory below. It has a major role in removing carbon dioxide from the atmosphere and storing it for centuries or longer. The twilight zone is also known to the largest migration on Earth. Huge numbers of fishes and zooplankton (浮游动物) move hundreds of metres towards the surface each night to feed, before withdrawing back down at dawn.
Yet the zone is poorly understood — physically, biogeochemically and ecologically. Even the number of organisms that live there remains a mystery, let alone their diversity and function.
It is alarming, then, that this vast ocean domain is at risk in three ways-even before any of the potential consequences are understood. First, the world’s growing population has an increasing need for food. Second, sea-floor mining for minerals and metals could release waste into the region. And third, climate change is varying temperature, acidification and oxygen levels in ways that are likely to affect life there.
The twilight zone is hard Io study. Its organisms are difficult to sample and analyse, being thinly distributed, almost invisible and often fragile. They also live at pressures of up to 100 atmospheres, which poses problems for laboratory-based investigations.
Critics might argue that walers near coasts and above shelves are more deserving of study, given the huge environmental pressures there, as well as their importance to societies. And, of course, they need attention. Sadly, however, it is too late to avoid widespread environmental damage to these inshore regions. Instead, research efforts and local policies must aim at minimizing the worst effects.
By contrast, the twilight zone is almost left in its original condition. Moreover, the majority of it lies beyond national administration. This makes it of common interest and responsibility, and means that global agreement is necessary to manage it.

8 . Success and Risk in Extreme Sports
What is it that drives some to take extreme risks, while the rest of us hurry for the safety of the sidelines?
Lester Keller, sports-psychology expert, says that not everyone has the mental makeup to do well in extreme sports. He notes that most of us hit a natural ceiling that limits our appetite for extreme risk in tricky conditions. But others have a much higher tolerance for risk. Keller points to a top ski racer. He told Keller that “the high element of risk makes you feel alive, tests what you are made of and how far you can take yourself”. He said he would get nervous on some of the courses, but that this would just make him fight more.
Psychologists note that some people seem to have a strong desire for adrenaline (肾上腺素) rushes as a behavior seeking excited feelings. Like many extreme athletes, Emily Cook’s appetite for risk appeared at a young age. “I was a gymnast,” she said. “I was one of those kids who enjoyed and did well at anything where you were upside down.” As she started doing harder tricks, she was drawn to the challenge. “There are moments when you’re up there doing a new trick and it seems like an impossible thing. But overcoming that is just the coolest feeling in the world.”
Shane Murphy, sports professor, has worked with groups climbing Everest. “To me, that just seems like the height of risk,” he said. “But to them it was the next step in an activity that they’ve prepared for years.” Murphy said the view of extreme athletes is different from our own. “We look at a risky situation and know that if we were in that situation we would be out of control. But from the athletes’ view, they have a lot of control, and there are many things that they do to minimize risk.”
Another aspect of risk perception (认知) may be something referred to as “the flow”, a state in which many athletes become absorbed in the acts that focus the mind completely on the present. “Something that makes you try doing a tougher climb than usual, perhaps, is that your adrenaline flows and you become very concentrated on what you’re doing,” Murphy says. “After it’s over, there’s great excitement.”
People of different skill levels experience the flow at different times. Some may always be driven to adventures that others consider extreme. “I can enjoy hitting a tennis ball around, because that’s my skill level,” Murphy says. “But others might need the challenge of Olympic competition.”
1. By using the term “natural ceiling” in Paragraph 2, Lester Keller points out that ______.| A．extreme athletes must learn special skills |

| C．Most people lack the focus required to take bigger risks. |
| D．A certain state of mind makes attempting an activity more likely. |
| A．risk-taking is something you either naturally do or avoid |
| B．those who take risks are more likely to be successful in life |
| C．extreme athletes are driven by a need to be better than others |
| D．taking part in extreme sports is not as difficult as people think |
9 . Alzheimer's AI
An estimated 5.7 million people in the U.S. have Alzheimer's disease-the most common type of dementia(痴呆）－and that number is expected to more than double by 2050. Early diagnosis is crucial for patients to benefit from the few therapies available. But no scans can deliver a conclusive diagnosis while a person is alive; instead doctors have to conduct numerous and complicated clinical and neuropsychological tests.So there is growing interest in developing artificial intelligence to identify Alzheimer's based on brain imaging.
Researchers at the University of California,San Francisco, have now successfully trained an AI algorithm(算法）to recognize one of the early signs of Alzheimer's-a reduction in the brain's glucose（葡萄糖）consumption-in positron emission tomography (PET) imaging.
The algorithm accurately predicted an eventual Alzheimer's diagnosis in nearly all the test cases, according to the study. In PET imaging, a very small amount of a radioactive compound are injected into the body, producing three-dimensional images of metabolism(新陈代谢）,circulation and other cellular activities. PET is well suited for an AI diagnostic tool because Alzheimer's leads to subtle changes in the brain's metabolism that begin years before neural(神经的） tissue starts to go downhill, says study co-author Jae Ho Sohn,a radiologist at UCSF. These changes are "very hard for radiologists to pick up,"he notes.
The algorithm was trained and tested on 2,100 PET brain images from about 1,000 people 55 years and older. The images came from a 12-year study that tracked people who would ultimately be diagnosed with Alzheimer's, as well as those with mild memory declines and healthy control participants. The algorithm was trained on 90 percent of the data and tested on the remaining 10 percent. It was then retested on a second, independent data set from 40 patients monitored for 10 years. The algorithm was highly sensitive and was able to recognize 81 percent of the patients in the first test group and 100 percent in the second who would be diagnosed with Alzheimer's six years later, on average. The findings were published in February in Radiology.
The algorithm is based on "deep learning ,a machine-learning technique that uses artificial neural networks programmed to learn from examples. "This is one of the first promising,preliminary(初步的） applications of deep learning to the diagnosis of Alzheimer's," says Christian Salvatore, a physicist at Italy's National Research Council, who was not involved in the study. “The model performs very well when identifying patients with mild or late diagnoses", he says, “but catching it in the earliest stages remains one of the most critical open issues in this field."

10 . “Do not tell anyone”. We often hear these words when someone tells us a secret. But keeping a secret is hard. We’re often tempted（引诱）to “spill the beans”, even if we regret it later.
According to the professor, Asim Shah, keeping a secret may well “become a burden”. This is because people often have an “eager and anxious urge（冲动）to share it with someone”. An earlier study, led by Anita, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted（托付）with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.
Secrets are so often getting out. Why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone, ”according to Shah.
He added that talkative people could let secrets slip out. But this doesn’t mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.
Shah said that to judge whether to tell someone a secret, you’d better put yourself in their position, Think about how you would feel to be told that you mustn’t give the information away. Shah also recommended that if you accidentally give up someone’s secret you should come clean about it. Let the person know that their secret isn’t so secret anymore.
1. Why does the author say keeping a secret may “become a burden”?| A．Because people are born not to be able to keep secrets. |
| B．Because when people have secrets, their bodies ache. |
| C．Because keeping secrets is certain to cause depression. |
| D．Because keeping secrets could probably be harmful to health. |
| A．2. | B．3. | C．4. | D．5. |
| A．To fall by accident. | B．To let out secrets on purpose. |
| C．To spread secrets to everyone around. | D．To give away secrets unintentionally. |
| A．Quiet people are more likely to keep the secrets to themselves. |
| B．Sharing secrets helps establish friendship or get over the, sense of guilt. |
| C．Putting yourself in others’ shoes helps realize the importance of keeping secrets. |
| D．A person who is asked to keep a secret will suffer from psychological problems only. |
