1 . On a September afternoon in 1940, four teenage boys made their way through the woods on a hill overlooking Montignac in southwestern France. They had come to explore a dark, deep hole said to be an underground passage to the nearby manor（庄园）of Lascaux. Squeezing through the entrance one by one, they soon saw wonderfully lifelike paintings of running horses, swimming deer, wounded wild oxen, and other beings—works of art that may be up to 20,000 years old.

The collection of paintings in Lascaux is among some 150 prehistoric sites dating from the Paleolithic period（旧石器时代）that have been documented in France's Vezere Valley. This corner of southwestern Europe seems to have been a hot spot for figurative art. The biggest discovery since Lascaux occurred in December 1994, when three cave explorers laid eyes on artworks that had not been seen since a rockslide 22,000 years ago closed off a large deep cave in southern France. Here, by unsteadily shining firelight, prehistoric artists drew outlines of cave lions, herds of rhinos（犀牛）and magnificent wild oxen, horses, cave bears. In all, the artists drew 442 animals over perhaps thousands of years, using nearly 400,000 square feet of cave surface as their canvas（画布）. The site, now known as Chauvet-Pont-1'Arc Cave, is sometimes considered the Sistine Chapel of prehistory.

For decades scholars had theorized that art had advanced in slow stages from ancient scratchings to lively, naturalistic interpretation. Surely the delicate shading and elegant lines of Chauvet's masterworks placed them at the top of that progression. Then carbon dates came in, and prehistorians felt shocked. At some 36,000 years old—nearly twice as old as those in Lascaux—Chauvet's images represented not the peak of prehistoric art but its earliest known beginnings.

The search for the world's oldest cave paintings continues. On the Indonesian island of Sulawesi, for example, scientists found a large room of paintings of part-human, part-animal beings that are estimated to be 44,000 years old, older than any figurative art seen in Europe.

Scholars don't know if art was invented many times over or if it was a skill developed early in our evolution. What we do know is that artistic expression runs deep in our ancestry.

2 . The 2021 Nobel Economics Prize has been awarded to Robert Wilson and Paul Milgrom for their work in analyzing auctions and how to make them more efficient.

At the heart of the work for which Milgrom and Wilson have been awarded is the winner's curse.     1     . An example might be the right to mine a certain area for gold. If no gold is found, the right will be worthless; but if there turns out to be a lot of gold, it will be valuable. Different bidders may have different opinions about how much hold is on the site.The more optimistic they are, the more they will be willing to bid. The most optimistic bid will win. But the true value is likely to turn out much closer to the average rather than the highest valuation,so winning bidders are likely to overpay.

Wilson's work has shown that the fear of the winner's curse leads rational bidders to bid less than the own valuation.     2     .Their final price will therefore be lower.

Milgrom built on this to examine the case of auctions where there is not only a common value but also a private value that differs between bidders. In focusing again on the winner's curse, Milgrom determined that English-style auctions, where the price starts low and is bid upward, are better at avoiding the winner's curse than Dutch-style auctions---where the price starts high and is bid downward.This is because bidders gain more information about an item's value during an English-style auction,as other bidders drop out.     3     .

How have such insights help society? For one thing, Milgrom and Wilson developed the Simultaneous Multiple Round Auction'(SMRA). In these auctions, all biddable items are offered at the same time and bidders can bid on any portion of the items.The SMRA is useful,for example,if a company wants to bid for a license in one area only if it can also have the license in another area.    4     . Running auctions simultaneously allows governments to maximize the prices of valuable assets.This gives governments more money to spend on public services like health and education.

A．If the auctions were held sequentially,the uncertainty about winning the second auction would depress bids in the first auction.

B．It arises from common value auctions where people bid for something whose value is unknown at the time but will be agreed upon later.

C．From determining the placement of every ad on a webpage to assigning the rights to fly to hub airports,auctions play a big role in contemporary society.

D．Greater uncertainty or the belief that some participants have more information than others will make bidders even more cautious.

E．He found that more details about the object's value,such as other bidders' valuations,tend to result in higher revenue.

F．This year's Nobel Economics Prize is a clear example of the practical effects on the interests of the public.

China's BeiDou System Prepared for Serving Whole World

China launched the last satellite of the BeiDou Navigation Satellite System (BDS) on June 23, marking the completion of the country's homegrown orbital navigation network in a(n)     1    step towards the peaceful exploration of space.

The BeiDou network, a major infrastructure domestically constructed and operated, can better meet the demands of China's national security, economic as well as social development. It can also provide more stable and reliable services, as well as a(n)     2     to the U.S.-owned Global Positioning System(GPS) for global users.

Given the national security concerns due to GPS's     3    ,China has not been the only nation in the world to have striven to develop its own satellite navigation system.Thus one of the BDS's primary principles has been local innovation. The key components as well as     4     technologies and software of the BDS have all been independently developed and manufactured by China itself. Such an independent drive in the field of scientific and technological research and development     5     the very spirit that had been pursued by many Chinese scientists who had once dedicated themselves to the "Two Bombs, One Satellite" project when China had been under nuclear threat by some of the world's major powers.

After 26 years of difficult work, the BDS has now earned a global reputation for its high-accuracy service and various service capabilities. According to the United Nations Office for Outer Space Affairs, the services provided by BeiDou are already helping to     6    social and economic development around the world.

Indeed, the BDS-based solutions have already been successfully adopted in     7    field as land registration, precise agriculture, digital construction and the monitoring and management of vehicles and ships. Also, the BDS-enabled products have already been exported to more than 100 countries, providing users with a variety of choices and an enhance     8     experience.

Thousands of years ago, the Chinese invented the compass, which had made long-range voyages on rough and vast seas possible, helping to give directions in the Age of Discovery.

Today, the BDS network is prepared to promote an even stronger global     9    in this age of globalization, helping countries worldwide to     10     their own courses towards a better future.

A Deeper Meaning behind Souvenirs

“Nobody sits us down and tells us to collect objects when we’re young,” writes Rolf Potts, “it’s just something we do, as a way to    1    ourselves with the world, its possibilities, and our place in it.”

Few of us would call ourselves collectors, but most travelers     2    a seashell from a vacation, or bring a keychain. As Mr. Potts notes in a book called “Souvenir,” there is more to this     3    simple practice than meets the eye. For one thing, it can date back to the oldest described journeys, so it’s a    4    practice that goes back thousands of years. And academic researchers have classified souvenirs -- even    5    items like “I Love New York” T-shirts and plastic miniatures of Michelangelo’s David -- into various categories, likely unknown to many travelers.

Which categories do the things we’ve bought or found in our travels fall into? Further, what’s     6    behind our need to bring home souvenirs?

Over time, intellectual curiosity became the driving    7    for personal travel. Yet even as travelers began collecting historical and scientific souvenirs, not just religious items, the things they brought home stood for feelings for holy objects.

Scholars    8    these souvenirs into different buckets, including “markers” (location branded items like T-shirts and teacups), “pictorial images” (postcards and posters), and “    9    landmarks” (for example, Statue of Liberty key chains), with the latter two categories symbolizing, though not exclusive to, mass tourism.

In the end, “Souvenir” suggests that its meaning is not fixed because its importance to the owner can change over time and that its significance is closely related to the traveler’s identity. Mr. Potts himself has had plenty of souvenirs, things that remind him not merely of the places he’s been and the extraordinary     10    between him and local people, but of former life phases. “When we collect souvenirs,” he writes, “we do so not to evaluate the world, but to tell the self.”

5 . Last year Miranda Lim found that taking care of three young children homebound by the pandemic meant she often had to work late into the evening to stay on top of her job. Concerned that the _________ hours were having a bad effect on her sleep, Lim started tracking her sleep time with an app on her mobile phone. She wasn’t quite _________ the results. “I saw my bedtime was _________ anywhere between 9 p.m. and 3 a.m.,” she says. “I was just horrified.” As a result, she immediately set up a daily alarm — not for waking up, but for _________ to bed at a reasonable hour.

It’s _________ why Lim would be a bit of an alarmist when threatened with a lack of a constant night’s sleep. As a sleep disorders physician at the VA Portland Health Care System, Lim is at the forefront of a global team of medical researchers who have in recent years been _________ the ways in which even moderate sleep shortage in middle age strongly link to Alzheimer’s disease later in life. She says, “Our big discovery was that the lack of sleep involves brain processes that may _________ into the disease.”

The finding that getting more and better sleep could offer the best, and _________ only, way to significantly reduce the risks of neuro-degeneration (神经退化) in older age is likely to further _________ an already hot sleep industry. Market research firm Infinium Global Research puts the current worldwide market for sleep __________ — including drugs, special bedding, and health care services — at an estimated $80 billion–plus, and predicts it will __________ to $114 billion over the next five years. Research firm BCC has been projecting a similar growth rate. Now Tim O’Brien, who heads life sciences content at BCC, says he’s watching for “a sudden leap”.

That leap would be driven not only by consumer’s __________ pursuit of better sleep-related health, but also by a stream of new __________ and technologies that are emerging to help achieve it, from sleep drugs to implantable medical devices to smart pillows. Fitbit’s companion app offers a range of insights and exercises aimed at __________ sleep, including sleep “scores” that break down different aspects of sleep, recommendations for when to get to bed and when to wake up, deep breathing and mindfulness exercises, and more. In addition, a big push into the market is being made by __________ a number of sleep-tracking and sleep-promoting features into the latest version of its “Nest Hub” smart speaker-and-screen device.

Nevertheless, some experts think the tech can help with slight pushes, but people still have to develop the healthy habits.

6 . Hugely ambitious in scope, The Lord of the Rings occupies an uncomfortable position in 20th century literature. This book of J.R.R.Tolkien’s poses a challenge to modern literature and its defenders. (Tolkien on his _______: “Some who have read the book, or at any rate have reviewed it, have found it boring, ridiculous, or annoying; and I have no cause to complain, since I have similar opinions of their works, or of the kinds of writing that they evidently _________.”) Yet The Lord of the Rings has enjoyed massive and enduring popularity. It would seem that Tolkien’s work supplied something that was _________ among the formal innovations of 20th century fiction, something for which readers were hungry. But what was it, and why was it important?

It seems that the key point lies in Tolkien’s wholehearted rejection of modernity and modernism. This is what so powerfully _________ some readers, and just as powerfully drives away others. In his book J.R.R.Tolkien: Author of the Century, T.A. Shippey expands on this idea by arguing that Tolkien saw his story of Middle-earth not as fiction or invention, but as the _________ of something genuine that had become buried beneath the fairy tale and nursery rhythm.

“However fanciful Tolkien’s creation of Middle earth was,” Shippey writes, “he did not think that he was entirely _________. He was ‘reconstructing’, he was harmonizing conflicts in his source-texts, sometimes he was supplying entirely new concepts, but he was also reaching back to an imaginative world which he believed had once really _________, at least in a collective imagination.”

The book is also deeply grounded in Tolkien’s linguistic expertise （语言专长） —he _________ whole languages for his characters. Sometimes he became so absorbed in the creation of languages, in fact, that he _________ the story itself for months or years at a time, believing he could not continue until some inconsistency（不一致）in his invented world had been resolved. But Tolkien’s great intellect and knowledge is not the source of his ____________; without his storytelling gift, The Lord of the Rings would be little more than a curiosity. And this gift seems to originate straight from his ____________ to break from classical and traditional forms.

Tolkien himself often spoke of his work as something ‘found’ or ‘discovered’, something whose existence was ____________ of him. It’s wise to be careful with this sort of interpretation, but it seems ____________ that he believed his work to be something given, something revealed, which contained a kind of truth beyond measure. ____________, his details have the weight of reality, and because of this his great sweep of story feels real as well; you might say that his ____________ castles are built with a certain amount of genuine stone.

7 . The Thai government intends to further deepen its digital cooperation with Chinese technology company Huawei, senior Thai officials said at a cloud event held in Bangkok this week.

During the Powering Digital Thailand 2022 on Nov 17-19, Thai deputy Prime Minister Prawit Wongsuwon said digital infrastructure (基础设施), such as5G, is crucial to Thailand’s _________ and social development, especially for the country’s post-pandemic economic _________.

Badly hit by the COVID-19 pandemic, the tourism-reliant nation registered an economic reduction of 6.1 percent last year, the worst in more than 20 years. However, the pandemic has significantly speeded the _________ of digital technologies in Thailand, where Chinese tech companies have _________ advantages.

During the pandemic, Huawei used its technology to help local hospitals implement systems for automated medical supply, AI-backed _________ and remote treatment, which greatly improved the _________ of hospitals and made healthcare more _________.

Fueled by Thailand’s digital roadmap, Huawei has focused on helping the country build 20,000 5G stations in the past two years. _________, Thailand has more than 4.2 million 5G subscribers leading in 5G adoption among ASEAN (Association of Southeast Asian Nations) countries.

Another strength of Huawei has been its cloud capabilities. Deng Feng, general manager of Huawei Thailand, said Huawei Cloud is the only cloud service _________ with local data centers in Thailand, considering that data localization is a key trend of global enterprises due to government regulations as well as security concerns.

He emphasized the Huawei will support Thailand’s low-carbon and digital development in the future in four areas, including expanding 5G coverage and usage, providing cloud services, creating low-carbon development with digital energy, and __________ industry talents.

Thai Minister of Digital Economy and Society Chaiwut Thanakamanusorn expressed his hopes for __________ cooperation between the Thai government and Huawei to __________ the country’s digital economy, which is targeted to __________ 30 percent of the GDP by 2030.

According to a joint report released by Google, Temasek and Bain & Company earlier this month Thailand’s digital economy is expected to __________ $30 billion this year, up 51 percent, making it the second-largest market in Southeast Asia after Indonesia.

Huawei’s Rotating Chairman Guo Ping said the company will continue __________ and building a tech ecosystem to facilitate faster digitalization in Asia-Pacific, and invest $100 million over the next three years to build a startup ecosystem in the region.

8 . This era of “Industry 4. 0” is being driven by the same technological advances that enable the capabilities of the smartphones in our pockets. It is a mix of low-cost and high-power computers, high-speed communication and artificial intelligence. This will produce smarter robots with better sensing and communication abilities that can _________ different tasks, and even adjust their work to meet demand without the input of humans.

In the manufacturing industry, where robots have arguably made the most headway of any division, this will mean a(n) _________ shift from centralized to decentralized cooperative production. _________ robots focused on single, fixed, high - speed operations and required a highly skilled human workforce to operate and maintain them. Industry 4. 0 machines are flexible, cooperative and can operate more independently which _________ removes the need for a highly skilled workforce.

For large-scale manufacturers, Industry 4. 0 means their robots will be able to sense their environment and communicate in an industrial network that can be run and _________ remotely. Each machine will produce large amounts of data that can be _________ studied using what is known as “big data” analysis. This will help _________ ways to improve operating performance and production quality across the whole plat, for example by better predicting when repairing is needed and automatically _________ it.

For _________ manufacturing businesses, Industry 4. 0 will make it cheaper and easier to use robots. It will create machines that can be rearranged to perform __________ jobs and adjusted to work on a more diverse product range and different production volumes. This part is already beginning to benefit from robots designed to cooperate with human workers and analyse their own work to look for __________.

While these machines are getting smarter, they are still not as smart as us. Today's industrial artificial intelligence operates at a __________ level, which gives the appearance of human intelligence exhibited by machines, but designed by humans.

What's coming next is known as “deep learning”. Similar to big data analysis, it involves processing large quantities of data in real time to __________ what is the best action to take, The __________ is that the machine learns from the data so it can improve its decision making. A perfect example of deep learning was __________   by Google's Alpha Go software, which taught itself to beat the world's greatest Go players.

9 . Hello, Stranger

Attitudes to strangers tend to follow a familiar pattern. Children are taught never to speak to unknown grown-ups, especially those regarded by their parents as untrustworthy. The onset of adolescence and young adulthood brings a bursting desire to interact with all sorts of people, which. of course, might not gain family approval.

    1    

Social circles generally narrow again as people find life-partners, form households and produce offspring of their own. Time becomes scarce; new friendships are often based on sharing the burden of child care.     2    As is often the ease, that is because professional duties expand even as parental ones diminish. Then in old age, even if ouriosity and charisma remain undimmed, lack of mental and psychological energy makes new serendipitous connections harder to establish.

But that is not the whole story.     3     However short, it somehow touches a nerve. It might involve nothing more than a smile, or a chance remark that hits an emotional spot; or it might be an unexpectedly deep conversation on a plane or train, a surge of mutual understanding that is life-affirming even if the companion is never seen again.

In the age of covid-19 and Zoom, the chronological pattern has been changed. Instead of their vague possibilities and risks, strangers have assumed the all-too-literal role as a looming source of infection. During lock-downs they are officially to be avoided. Yet youngsters still long dangerously, for the pleasure of interaction, not just with individuals but anonymous crowds.     4     And we can hear the burden of wearing a mask through the whole movie just to enjoy the comforting sense of fellowship in a cinema or theatre audience.

A．This aspect of the story and fear of strangers has bring about frustration among people.

B．Some people never recover the youthful enthusiasm for unforeseen encounters.

C．Middle-aged people gradually realize that the exchange will be a one-off which can permit freedom and frankness.

D．People of all ages have come to miss the human stimulation of busy high streets or trains.

E．In mid-life and beyond people can still experience the joy of a random meeting.

F．Despite this, the resulting interactions can generate an appealing feeling of escaping familiarity.

10 . In American culture, I am noticing a lack of respect, especially among children. This should be treated _________ since disrespectful children will become disrespectful teenagers, and then disrespectful adults. American culture is _________ the ways of teaching respect, while other cultures have methods that Americans could learn from.

In 1995, I spent a couple of months in Kenya where I lived with a pastor’s family. This pastor was a part of the Maasai tribes that have some unique customs. One of them is the _________ that the children give the adults. When an adult approaches a Maasai child, the child will _________ and tilt their head slightly saying “Suppa”. The adult responses by saying “Ippa” touching the top of their heads. This simple act shows respect for the adult. The children _________ that they are their elder and that the adult deserves respect.

In my early 20’s, I worked at a children’s home in South Carolina where the children from 4 to 19 years old were taught to respect their elders. They _________ me as “Mr. Vince” and every adult worker there with a “Mr, Mrs, or Ms.”. However, as I counsel and talk to teachers and other professionals who work with children now, there seems to be a _________ in such as friendly behavior that children give adults. Fewer students treat teachers with respect: Children frequently talk back to their teachers, parents or seniors, interrupt conversations, and disregard their _________. Children casually speak with other adults like waiters, store clerks, postmen, cashiers, etc. in the way as if they are children’s _________.

Immanuel Kant expressed two __________ attitudes in Europe that are still dominant today. One is that only humans are persons because they have autonomy—they freely choose to act on principles by __________ laws on themselves, and not on desires. It is this mind based on __________ that gives humans special status. Second, to learn to follow principles instead of desires, a human child needs to learn __________ to the laws of adults. They must practice __________ regulation before they are able to practice autonomy. Kant said that “act in the way you want others to act in the situation, taking other people as persons, not __________ you use for your own goals”. Only in this way can you become a real person with intrinsic values.
