But today’s teens have grownup with smartphones. Compared with teens a couple of decades ago, the way they interact with traditional media like books and movies is fundamentally diff erent.B) Analysis of surveys of over one million teens in the United States collected since 1976 reveals a major shift inhow teens are spending their leisure time. Paper books are being ignored, in favor of screens. Digital devices are changing other behaviors, too. More and more, young people choose spending time on their electronic devices over engaging in other activities, regardless of the type. Indeed, by 2016, the average American high school senior said they spent six hours a day writing text messages, on social media, and online during their free time. And that covers just three activities, and if other digital media activities were included, that estimate would no doubt rise.C)Teens did not always spend that much time with digital media. Online time has doubled since 2006, andsocial media use has moved from a periodic activity to a daily one in the same period. By 2016, nearly nine out of ten young women in the 12th grade said they visited social media sites every day. Meanwhile, time spent playing video games rose from under an hour a day to an hour and a half on average. One out of ten American 8th grade students in 2016 spent 40 hours a week or more playing video games. Let me emphasize that this is equal to the time most adults spend per week at work.D)If teens are spending so much time using electronic devices, does that mean they have to give up some otheractivities? Maybe not. Over the years, many scholars have insisted that time online does not necessarily take away time spent engaging with traditional media or on other activities. Some people, they argue, are just more interested in certain kinds of media and entertainment. Thus, using more of one type of media does not necessarily mean less of the other.E)That may be true, but that still does not tell us much about what happens across a whole generation of peoplewhen time spent on digital media grows. Large surveys conducted over the course of many years tells us that American youth are not going to the cinema nearly as often as they did in the past. While 70 percent of 8th and 10th grade students used to go to the movies once a month or more, now only about half do this.More and more, watching a movie is something teens choose to do on their electronic devices. Why is thisa problem? One reason is that going to the cinema is generally a social activity. Now, watching movies issomething that most teens do alone. This fits a larger pattern. In another analysis, researchers found that today’s teens go out with their friends much less often than previous generations did.F)But the trends related to movies are less disturbing compared with the change in how teens spend their time.Research has revealed an enormous decline in reading. In 1980, about 60 percent of senior high school students said they read a book, newspaper or magazine every day that was not assigned for school. By 2016, only 16 percent did. This is a huge drop and it is important to note that this was not merely a decline in reading paper books, newspapers or magazines. The survey allowed for reading materials on a digital device.G)Indeed, the number of senior high school students who said they had not read any books for pleasure in thelast year was one out of three by 2016. That is triple the number from two decades ago. For today’s youth, books, newspapers and magazines have less and less of a presence in their daily lives. Of course, teens are still reading. But they are generally reading short texts. Most of them are not reading long articles or books that explore deep themes and require critical thinking and refl ection. Perhaps not accidentally, in 2016 reading scores were the lowest they have ever been since 1972.H)This might present problems for young people later on. When high school students go on to college, theirpast and current reading habits will infl uence their academic performance. Imagine going from reading texts as short as one or two sentences to trying to read entire books written in complex language and containing sophisticated ideas. Reading and comprehending longer books and chapters takes practice, and American teens are no longer getting that practice.I)So how can this problem be solved? Should parents and teachers take away teens’ smartphones and replacethem with paper books? Probably not. Research has shown that smartphones are currently American teens’ main form of social communication. This means that, without a smartphone, teens are likely to feel isolated from their peers. However, that does not mean teens need to use electronic devices as often as they do now.Data connecting excessive digital media time to mental health issues suggests a limit of two hours a day of free time spent with screens, a restriction that will also allow time for other activities—like going to the movies with friends or reading longer, more complicated texts.J)The latter is especially important. I would argue that of all the changes brought about by the widespread use of digital devices, the huge decline in reading is likely to have the biggest negative impact on today’s teens because reading books and longer articles is one of the best ways to learn critical thinking. It helps people to understand complex issues and to separate fact from fi ction. Thus, deep reading is crucial for being a good citizen, a successful college student and a productive employee. If serious reading dies, a lot will go with it.36. Many years’ surveys reveal that young people in America are going to the cinema much less often than theyused to.37. Survey analysis shows American teens now spend their leisure time on digital devices rather than readingprinted books.38. The number of senior high schoolers not reading books for pleasure in a year increased three times over 20years.39. Many scholars claim that spending time on electronic devices doesn’t necessarily mean a decrease of time forother activities.40. Most people spend much more time interacting with digital media than they did ten years ago.41. The author claims that it will be a great loss if we no longer read books and longer articles.42. Over a decade or so, American teens’ social media use shifted from an occasional activity to a routine one.43. A more disturbing trend in America today is that teens are spending far less time reading than around fourdecades ago.44. Some fi ve years ago, high school seniors in America generally spent more than six hours a day on electronicdevices.45. It was found that American youngsters today don’t socialize nearly as much as the earlier generations.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Have you ever wondered how acceptable it is to hug or touch someone? While it may sound safe to avoid all physical contact so as not to off end anyone, the lack of touching might imply cold attitudes or indiff erence in interpersonal relationships.So, what should we do? The simple answer is to thoroughly learn unique cultural norms for physical contact. In nonverbal communication terminology (术语)，physical contact and the study of touching are generally referred to as haptics.Haptics in communication often suggest the level of intimacy. They are usually classifi ed into two groups: high-contact and low-contact.Asia and quite surprisingly the United States, Canada and Britain belong to low-contact cultures. People from the rest of the world, such as Latin America, are considered to be in high-contact cultures, where they tend to expect touching in social interactions and feel more comfortable with physical closeness. Despite the classifi cation, there are more complex factors such as relational closeness, gender, age, and context that can aff ect how someone views physical contact.One common French custom of greetings is cheek-kissing, but it is mostly restricted to friends, close acquaintances and family members. While cheek-kissing for Latin Americans is also a universal greeting form, it does not require such a high degree of relational closeness. However, gender matters more for them because cheek-kissing often only happens between women or a man and a woman but not two men.In contrast, in certain Arabian, African, and Asian countries, men can publicly hold hands or show physical affection as signs of brotherhood or friendship while these behaviors may suggest a romantic relationship in other parts of the world. Although men’s touching is more normal in these cultures, physical contact between persons of opposite sexes who are not family members is negatively perceived in Arabian countries.These factors could definitely affect the degree to which someone is comfortable with tactile(触觉的) communication and physical intimacy. Therefore, if you are someone who loves to show physical aff ection, you should not be afraid to show it or drastically change your behaviors—just ask for consent beforehand!46. What does the author say in the fi rst paragraph about physical contact?A)Its role in interpersonal relationships is getting increasingly important.B)It is becoming more acceptable to many who used to think it off ensive.C)Its absence might suggest a lack of warmth in interpersonal relationships.D)It might prompt diff erent responses from people of diff erent social backgrounds.47. What does physical contact in communication suggest?A)What social class people belong to.C)What family background people come from.B)How civilized the communicators are.D)How close the communicators’ relationships are.48. What do we learn about p eople in high-contact cultures?A)They are sensitive to the way people express their emotions.B)They take touching as a cultural norm in social interactions.C)They attach great importance to close ties among people.D)They tend to be more open in interpersonal relationships.49. What do we learn about social customs in Arabian countries?A)Men can show friendship in public through physical aff ection.B)Non-traditional romantic relationships are simply unacceptable.C)Physical contact between unfamiliar people is negatively perceived.D)People of diff erent ages and genders show aff ection in diff erent ways.50. What does the author tell us to do concerning tactile communication?A)Lay emphasis on nonverbal communication.C)Pay attention to the diff erences between genders.B)Learn to use appropriate body language fi rst.D)Take other people’s preference into consideration. Passage TwoQuestions 51 to 55 are based on the following passage.From climate change to the ongoing pandemic (大流行病) and beyond, the issues facing today’s world are increasingly complex and dynamic. Yet solving problems like these requires new approaches that extend beyond traditional ways of thinking. A study led by Yale Professor of Psychology, Paul O’Keefe, found that having a growth mindset (思维倾向) of interest may spark this type of innovation.Professor O’Keefe established in earlier studies that people hold diff erent beliefs about the nature of interest. Those with a growth mindset of interest tend to believe that interests can be developed and cultivated, while those with a fi xed mindset of interest tend to believe that interests are inherent (与生俱有的) and simply need to be ‘found.’ Building on these fi ndings, the latest research examined how a growth mindset of interest can boost integrative thinking across the traditional disciplinary boundaries of arts and sciences.For example, in one task, research participants were instructed to create new college majors by combining two or more existing academic Arts or Science programs at their university. After coding and analyzing the ideas they generated, the team found that people with a growth mindset of interest were more likely to bridge programs across the arts and sciences to create new majors like computational economics rather than creating majors that drew from only one of those areas, like computational chemistry.As Professor O’Keefe pointed out, “This research provides a useful direction for organizations whose products and services call for integrated and creative solutions. Take smartphones for example. You need not only computer science and engineering knowledge, but also an understanding of psychology and visual design to create a better product. Employees with a growth mindset may be more likely to devise innovative ideas that bridge multiple areas of knowledge to achieve better solutions. ”The benefi ts of a growth mindset of interest may also extend to those seeking employment. This is a pressing issue because many people are becoming unemployed due to the COVID-19 pandemic. Having a growth mindset of interest can help job seekers expand their interests and become more adaptable to diff erent fi elds, and take the initiative to learn new skills.51. What does the author say about the world today?A)It faces problems that are getting more varied and complicated.B)It has done away with many of the traditional ways of thinking.C)It is undergoing radical and profound changes.D)It is witnessing various types of innovations.52. What did Professor O’Keefe fi nd in his earlier studies?A)People’s interests tend to change with age.C)People are divided about the nature of interest.B)People’s interests determine their mindsets.D)People of diff erent ages have diff erent mindsets.53. What is the focus of Professor O’Keefe’s recent research?A)How boundaries can be removed between arts and science disciplines.B)How feasible it is to create new disciplines like computational economics.C)How students in arts and sciences view the two types of mindset of interest.D)How a growth mindset of interest can contribute to cross-disciplinary thinking.54. What does the author want to illustrate with the example of smartphones?A)Hi-tech products are needed in interdisciplinary research.B)Improved technology gives birth to highly popular products.C)Making innovative products needs multidisciplinary knowledge.D)Hi-tech products can boost people’s integrative thinking.55. What is the author’s suggestion to those who are seeking employment?A)Learning practical skills.C)Staying safe in the pandemic.B)Broadening their interests.D)Knowing their pressing issues.Part IV Translation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

The 26 is that loneliness is a huge, if silent, risk factor.Loneliness affects physical health in two ways. First, it produces stress hormones that can lead to many health problems. Second, people who live alone are less likely to go to the doctor 27, to exercise or to eat a healthy diet.Public health experts in many countries are 28 how to address widespread loneliness in our society. Last year Britain even appointed a minister for loneliness. "Loneliness 29 almost every one of us at some point," its minister for loneliness Baroness Barran said. "It can lead to very serious health 30 for individuals who become isolated and disconnected."Barran started a "Let's Talk Loneliness" campaign that 31 difficult conversations across Britain. He is now supporting 32 benches, "which are public seating areas where people are encouraged to go and chat with one another. The minister is also 33 to stop public transportation from being cut in ways that leave people isolated More than one-fifth of adults in both the United States and Britain said in a 2018 34 hat they often or always feel lonely.More than half of American adults are unmarried, and researchers have found that even among those who are married, 30% of relationships are 35 strained.

Each paragraph is markedwith a letter. Answer the question by marking the corresponding letter on Answer Sheet 2.What happens when a language has no words for numbers?[A] Numbers do not exist in all cultures. There are numberless hunter-gatherers embedded deep in Amazonia,living along branches of the world s largest river tree. Instead of using words for precise quantities, these people rely exclusively on terms analogous to “a few” or “some.”In contrast, our own lives are governed by numbers. As you read this, you are likely aware of what time it is, how old you are, your checking account balance, your weight and so on. The exact (and exacting) numbers we think with impact everything from our schedules to our self-esteem.[B] But, in a historical sense, numerically fixated people like us are the unusual ones. For the bulk of ourspecies’approximately 200,000-year lifespan, we had no means of precisely representing quantities.What’s more, the 7,000 or so languages that exist today vary dramatically in how they utilize numbers. [C] Speakers of a numeric, or numberless, languages offer a window into how the invention of numbersreshaped the human experience. In a new book, I explored the ways in which humans invented numbers, and how numbers subsequently played a critical role in other milestones, from the advent of agriculture to the genesis of writing. Cultures without numbers, or with only one or two precise numbers, include the Munduruku and Piraha in Amazonia. Researchers have also studied some adults in Nicaragua who were never taught number words. Without numbers, healthy human adults struggle to precisely differentiate and recall quantities as low as four. In an experiment, a researcher will place nuts into a can one at a time, then remove them one by one. The person watching is asked to signal when all the nuts have been removed. Responses suggest that anumeric people have some trouble keeping track of how many nuts remain in the can, even if there are only four or five in total.[D] This and many other experiments have converged upon a simple conclusion: When people do not havenumber words, they struggle to make quantitative distinctions that probably seem natural to someone like you or me. While only a small portion of the world s languages are anumeric or nearly anumeric, they demonstrate that number words are not a human universal.[E] It is worth stressing that these anumeric people are cognitively normal, well-adapted to the environs theyhave dominated for centuries. As the child of missionaries, I spent some of my youth living with anumeric indigenous people, the aforementioned Piraha who live along the sinuous banks of the black Maici River. Like other outsiders, I was continually impressed by their superior understanding of the ecology we shared. Yet numberless people struggle with tasks that require precise discrimination between quantities. Perhaps this should be unsurprising. After all, without counting, how can someone tell whether there are, say, seven or eight coconuts in a tree? Such seemingly straightforward distinctions become blurry through numberless eyes.[F] This conclusion is echoed by work with anumeric children in industrialized societies. Prior to beingspoon-fed number words, children can only approximately discriminate quantities beyond three. We must be handed the cognitive tools of numbers before we can consistently and easily recognize higher quantities. In fact, acquiring the exact meaning of number words is a painstaking process that takes children years. Initially, kids learn numbers much like they learn letters. They recognize that numbers are organized sequentially, but have little awareness of what each individual number means. With time, they start to understand that a given number represents a quantity greater by one than the preceding number.This "successor principle" is part of the foundation of our numerical cognition, but requires extensive practice to understand.[G] None of us, then, is really a "numbers person." We are not predisposed to handle quantitative distinctionsadroitly. In the absence of the cultural traditions that infuse our lives with numbers from infancy, we would all struggle with even basic quantitative distinctions. Number words and written numerals transform our quantitative reasoning as they are coaxed into our cognitive experience by our parents, peers and school teachers. The process seems so normal that we sometimes think of it as a natural part of growing up, but it is not. Human brains come equipped with certain quantitative instincts that are refined with age, but these instincts are very limited. For instance, even at birth we are capable of distinguishing between two markedly different quantities – for instance, eight from 16 things. But we are not the only species capable of such abstractions.[H] Compared to chimps and other primates, our numerical instincts are not as remarkable as many presume.We even share some basic instinctual quantitative reasoning with distant non-mammalian relatives like birds. Indeed, work with some other species, including parrots, suggests they too can refine their quantitative thought if they are introduced to the cognitive power tools we call numbers.[I] So, how did we ever invent "unnatural" numbers in the first place? The answer is, literally, at yourfingertips. The bulk of the world's languages use base-10, base-20 or base-5 number systems. That is, these smaller numbers are the basis of larger numbers. English is a base-10 or decimal language, as evidenced by words like 14 ("four" + "10") and 31 ("three" x "10" + "one"). We speak a decimal language because an ancestral tongue, proto-Indo-European, was decimally based. Proto-Indo-European was decimally oriented because, as in so many cultures, our linguistic ancestors' hands served as the gateway to realizations like "five fingers on this hand is the same as five fingers on that hand." Such transient thoughts were manifested into words and passed down across generations. This is why the word "five" in many languages is derived from the word for "hand." Most number systems, then, are the by-product of two key factors: the human capacity for language and our propensity for focusing on our hands and fingers. This manual fixation – an indirect by-product of walking upright on two legs – has helped yield numbers in most cultures, but not all.[J] Cultures without numbers also offer insight into the cognitive influence of particular numeric traditions.Consider what time it is. Your day is ruled by minutes and seconds, but these entities are not real in any physical sense and are nonexistent to numberless people. Minutes and seconds are the verbal and written vestiges of an uncommon base-60 number system used in Mesopotamia millennia ago. They reside in ourminds, numerical artifacts that not all humans inherit conceptually.[K] Research on the language of numbers shows, more and more, that one of our species' key characteristics is tremendous linguistic(语言的) and cognitive diversity. If we are to truly understand how much our cognitive lives differ cross-culturally, we must continually sound the depths of our species' linguistic diversity.36. It is difficult for anumeric people to keep track of the change in numbers even when the total is very small.37. Human numerical instincts are not so superior to those of other mammals as is generally believed.38. The author emphasizes being anumeric does not affect one's cognitive ability.39. In the long history of mankind, humans who use numbers are a very small minority.40. An in-depth study of differences between human languages contributes to a true understanding ofcognitive differences between cultures.41. A conclusion has been drawn from many experiments that anumeric people have a hard timedistinguishing quantities.42. Making quantitative distinctions is not an inborn skill.43. Every aspect of our lives is affected by numbers.44. Larger numbers are said to be built upon smaller numbers.45. It takes great efforts for children to grasp the concept of number words.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decideon the best choice and mark the corresponding letter on Answer Sheet 2 with a single linethrough the centre.Passage OneQuestions 46 to 50 are based on the following passage.Sugar shocked. That describes the reaction of many Americans this week following revelations that, 50 years ago, the sugar industry paid Harvard scientists for research that shifted the focus away from sugar's role in heart disease-and put the spotlight（注意的中心）squarely on dietary fat.What might surprise consumers is just how many present-day nutrition studies are still funded by the food industry. Nutrition scholar Marion Nestle of New York University spent a year informally tracking industry-funded studies on food."Roughly 90%of nearly 170 studies favored the sponsor's interest," Nestle tells us. Other systematic reviews support her conclusions.For instance, studies funded by Welch Foods the brand behind Welch's 100%Grape Juice found that drinking Concord grape juice daily may boost brain function. Another, funded by Quaker Oats, concluded, as a Daily Mail story put it, that" hot oatmeal（燕麦粥）breakfast keeps you full for longer."Last year, The New York Times revealed how Coca-Cola was funding well-known scientists and organizations promoting a message that, in the battle against weight gain，people should pay more attention toexercise and less to what they eat and drink. Coca-Cola also released data detailing its funding of several medical institutions and associations between 2010 and 2015."It's certainly a problem that so much research in nutrition and health is funded by industry," says Bonie Liebman, director of nutrition at the Center for Science in the Public Interest."When the food industry pays for research, it often gets what it pays for."And what it pays for is often a pro-industry finding.Given this environment, consumers should be skeptical（怀疑的）when reading the latest finding in nutrition science and ignore the latest study that pops up on your news feed."Rely on health experts who've reviewed all the evidence," Liebman says, pointing to the official government Dietary Guidelines which are based on reviews of hundreds of studies."And that expert advice remains pretty simple," says Nestle." We know what healthy diets are lots of vegetables, not too much junk food, balanced calories. Everything else is really difficult to do experimentally."46. What did Harvard scientists do 50 years ago?A. They raised public awareness of the possible causes of heart disease.B. They turned public attention away from the health risks of sugar to fat.C. They placed the sugar industry in the spotlight with their new findings.D. They conducted large-scale research on the role of sugar in people's health.47. What does Marion Nestle say about present-day nutrition studies?A. They took her a full year to track and analyze.B. Most of them are based on systematic reviews.C. They depend on funding from the food industries.D. Nearly all of them serve the purpose of the funders.48. What did Coca-Cola funded studies claim?A. Exercise is more important to good health than diet.B. Choosing what to eat and drink is key to weight control.C. Drinking Coca-Cola does not contribute to weight gain.D. The food industry plays a major role in fighting obesity.49. What does Liebman say about industry-funded research?A. It simply focuses on nutrition and health.B. It causes confusion among consumers.C. It rarely results in objective findings.D. It runs counter to the public interest50. What is the author s advice to consumers?A. Follow their intuition in deciding what to eat.B. Be doubtful of diet experts' recommendations.C. Ignore irrelevant information on their news feed.D. Think twice about new nutrition research findings.Passage TwoQuestions 51 to 55 are based on the following passage.Success was once defined as being able to stay at a company for a long time and move up the corporate ladder. The goal was to reach the top, accumulate wealth and retire to a life of ease. My father is a successful senior executive. In 35 years, he worked for only three companies.When I started my career，things were already different. If you weren't changing companies every three or four years, you simply weren't getting ahead in your career. But back then, if you were a consultant or freelancer（自由职业者）, people would wonder what was wrong with you. They would assume you had problems getting a job.Today, consulting or freelancing for five businesses at the same time is a badge of honor. It shows how valuable an individual is. Many companies now look to these "ultimate professionals" to solve problems their full-time teams can't. Or they save money by hiring "top-tier(顶尖的)experts" only for particular projects.Working at home or in cafes，starting businesses of their own，and even launching business ventures that eventually may fail, all indicate "initiative,""creativity," and "adaptability," which are desirable qualities in today’s workplace. Most important, there is a growing recognition that people who balance work and play, and who work at what they are passionate about，are more focused and productive，delivering greater value to their clients.Who are these people? They are artists, writers，programmers，providers of office services and career advice. What's needed now is a marketplace platform specifically designed to bring freelancers and clients together. Such platforms then become a place to feature the most experienced，professional，and creative talent. This is where they conduct business. Where a sense of community reinforces the culture and values of the gig economy(零工经济)，and where success is rewarded with good reviews that encourage more business.Slowly but surely, these platforms create a bridge between traditional enterprises and this emerging economy. Perhaps more important, as the global economy continues to be disrupted by technology and other massive change, the gig economy will itself become an engine of economic and social transformation.51. What does the author use the example of his father to illustrate?A. How long people took to reach the top of their career.B. How people accumulated wealth in his father's time.C. How people viewed success in his father's time.D. How long people usually stayed in a company.52. Why did people often change jobs when the author started his career?A. It was considered a fashion at that time.B. It was a way to advance in their career.C. It was a response to the changing job market.D. It was difficult to keep a job for long.53. What does the author say about people now working for several businesses at the same time?A. They are often regarded as most treasured talents.B. They are able to bring their potential into fuller play.C. They have control over their life and work schedules.D. They feel proud of being outstanding problem-solver54. What have businesses come to recognize now?A. Who is capable of solving problems with ease.B. How people can be more focused and productive.C. What kind of people can contribute more to them.D. Why some people are more passionate about work.55. What does the author say about the gig economy?A. It may force companies to reform their business practice.B. It may soon replace the traditional economic model.C. It will drive technological progress on a global scale.D. It will bring about radical economic and social changes.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.铁观音(Tieguanyin)是中国最受欢迎的茶之一，原产自福建省安溪县西坪镇，如今安溪全县普遍种植，但该县不同地区生产的铁观音又各具风味。

They were first introduced to California by Spanish and Russian explorers and settlers many centuries ago. In the early times, pigs were allowed to wander freely and search a food. This practice also allowed many pigs to escape from farms and live in the wild, which became a problem.In fact, as one of the most damaging invasive species on the continent, wild pigs caused millions of dollars in crop damage yearly. TheyOY also harbored dozens of diseases that threaten both humans and farm animals. Forest patcheswith wild pigs have been found to have considerably reduced plant and animal diversity.In addition to either eating other animals or their food supply, wild pigs damaged native habitats by reaching up crosses and rubbing on trees. Their activities may also create opportunities for invasive plants to colonize these areas. Wild pigs will eat almost anything containing calories. Mice, deer, birds, snakes and frogs are among their victims.They can also harm other wild species through indirect competition rather than eating them or shrinking their food supply. On one particular United States island, wild pigs themselves became an attractive food source for a species of mainland eagle. Eagles began breeding on the island and also feeding on a species of native fox. The foxes were almost wiped out completely.Q16. What do we learn about early pigs in north America?Q17. Why are wild pigs a threat to humans?Q18. What does the passage say about the native foxes on a U.S. island? PASSAGE 2(19) A pair of entrepreneurs are planning to build and launch a spacecraft that would carry and roast coffee beans in outer space. The craft will use the heat of re-entry to roast coffee beans, as they float inside it in a pressurized tank. The effect would be to roast the beans all over and produce perfect coffee. (20) The businessmen say that on earth, beans can easily break apart and get burned in the roaster. But if gravity is removed, the beans float around and heated oven, received 360 degrees of evenly distributed heat and roast to near perfection. The spacecraft will reach a height of around200 kilometers. The beans would WANGYI then be roasted and the heat generated by the crafts 20 minute re-entry into earth's atmosphere. Temperatures and the pressurized tank will be kept to around 200 degrees Celsius. Once back on earth, the planet's first space roasted beans would be used to make coffee that would be sold for the first time in Dubai. This is where the Pairs company is based. It is not clear how much they would charge for a cup. Surprisingly, the space roaster concept should it go ahead will not be the first attempt to take coffee into space. (21) In 2015, two Italian companies collaborated on the construction of a similar type of spacecraft, which was the first coffee machine designed for use in space.Q19. What are a pair of entrepreneurs planning to do?Q20 . What does the passage say about coffee beans roasted on earth?Q21. What did the two Italian companies do in 2015?PASSAGE 3Passage threeIn cold and snowy Alaska, there’s a village called Takotna. It has a population of a mere 49 adults. Each March, this tiny village swells up in numbers because it is located in the middle of a race that takes place every year. It is a seven-day race called “The Iditarod Trail”. And participants stop at Takotna for the obligatory 24 hour rest.Lucky for them, Takotna is famous OY for its delicious fruit pies. Weeks before the competitors arrive, the residents of Takotna start preparing what is without question their biggest event of the year. The whole village chips in to help, including the kids, who end up developing their baking skills at an early age. Exhausted and hungry racers are greeted with delightful pies of all kinds, such as apple, orange, lemon, or banana.They consume the pies and a stomach warming race fuel. The toughness of the race allows for racers to eat pretty much whatever they want. The more calories, the better. Takotna has gained a reputation for its dessert-based hospitality since the 1970s. It started with one person, Jane Newton. Jane moved from Iditarod with her husband in 1972 and opened a restaurant. A rich and filling fruit pies quickly got the races attention, and the village gained some fame as a result. Proud residents then started to refer to Jane as queen of Takotna.Questions 22 to 25, or based on the passage, you have just heardQ22. Why do a lot of people come to the village of Takotna every March?Q23. What is the village of Takotna famous for?Q24. Who comes to help with the event of the year?Q25.

There are numberless hunter-gatherers embedded deep in Amazonia, living along branches of the world’s largest river tree. Instead of using words for precise quantities, these people rely exclusively on terms analogous to “a few”or “some.”In contrast, our own lives are governed by numbers. As you read this, you are likely aware of what time it is, how old you are, your checking account balance, your weight and so on. The exact (and exacting) numbers we think with impact everything from our schedules to our self-esteem.But, in a historical sense, numerically fixated people like us are the unusual ones. For the bulk of our species’approximately 200,000-year lifespan, we had no means of precisely representing quantities. What’s more, the 7,000 or so languages that exist today vary dramatically in how they utilize numbers.Speakers of anumeric, or numberless, languages offer a window into how the invention of numbers reshaped the human experience. In a 2017 book, I explored the ways in which humans invented numbers, and how numbers subsequently played a critical role in other milestones, from the advent of agriculture to the genesis of writing.Cultures without numbers, or with only one or two precise numbers, include the Munduruku and Pirahã in Amazonia. Researchers have also studied some adults in Nicaragua who were never taught number words.Without numbers, healthy human adults struggle to precisely differentiate and recall quantities as low as four. In an experiment, a researcher will place nuts into a can one at a time, then remove them one by one. The person watchingis asked to signal when all the nuts have been removed. Responses suggest that anumeric people have some trouble keeping track of how many nuts remain in the can, even if there are only four or five in total.This and many other experiments have converged upon a simple conclusion: When people do not have number words, they struggle to make quantitative distinctions that probably seem natural to someone like you or me. While only a small portion of the world’s languages are anumeric or nearly anumeric, they demonstrate that number words are not a human universal.It is worth stressing that these anumeric people are cognitively normal, well-adapted to the environs they have dominated for centuries. As the child of missionaries, I spent some of my youth living with anumeric indigenous people, the aforementioned Pirahã who live along the sinuous banks of the black Maici River. Like other outsiders, I was continually impressed by their superior understanding of the riverine ecology we shared.Yet numberless people struggle with tasks that require precise discrimination between quantities. Perhaps this should be unsurprising. After all, without counting, how can someone tell whether there are, say, seven or eight coconuts in a tree? Such seemingly straightforward distinctions become blurry through numberless eyes.This conclusion is echoed by work with anumeric children in industrialized societies.Prior to being spoon-fed number words, children can only approximately discriminate quantities beyond three. We must be handed the cognitive tools of numbers before we can consistently and easily recognize higher quantities.In fact, acquiring the exact meaning of number words is a painstaking process that takes children years. Initially, kids learn numbers much like they learn letters. They recognize that numbers are organized sequentially, but have little awareness of what each individual number means. With time, they start to understand that a given number represents a quantity greater by one than the preceding number. This “successor principle”is part of the foundation of our numerical cognition, but requires extensive practice to understand.None of us, then, is really a “numbers person.”We are not predisposed to handle quantitative distinctions adroitly. In the absence of the cultural traditions that infuse our lives with numbers from infancy, we would all struggle with even basic quantitative distinctions.Number words and written numerals transform our quantitative reasoning as they are coaxed into our cognitive experience by our parents, peers and school teachers. The process seems so normal that we sometimes think of it as a natural part of growing up, but it is not. Human brains come equipped with certain quantitative instincts that are refined with age, but these instincts are very limited. For instance, even at birth we are capable of distinguishing between two markedly different quantities –for instance, eight from 16 things. But we are not the only species capable of such abstractions. Compared to chimps and other primates, our numerical instincts are not as remarkable as many presume. We even share some basic instinctual quantitative reasoning with distant nonmammalian relatives like birds. Indeed, work with some other species, including parrots, suggests they too can refine their quantitative thought if they are introduced to the cognitive power tools we call numbers.The birth of numbersSo, how did we ever invent “unnatural”numbers in the first place?The answer is, literally, at your fingertips. The bulk of the world’s languages use base-10, base-20 or base-5 number systems. That is, these smaller numbers are the basis of larger numbers. English is a base-10 or decimal language, as evidenced by words like 14 (“four”+ “10”) and 31 (“three”x “10”+ “one”).We speak a decimal language because an ancestral tongue, proto-Indo-European, was decimally based. Proto-Indo-European was decimally oriented because, as in so many cultures, our linguistic ancestors’hands served as the gateway to realizations like “five fingers on this hand is the same as five fingers on that hand.”Such transient thoughts were manifested into words and passed down across generations. This is why the word “five”in many languages is derived from the word for “hand.”Most number systems, then, are the by-product of two key factors: the human capacity for language and our propensity for focusing on our hands and fingers. This manual fixation –an indirect by-product of walking upright on two legs –has helped yield numbers in most cultures, but not all.Cultures without numbers also offer insight into the cognitive influence of particular numeric traditions. Consider what time it is. Your day is ruled by minutes and seconds, but these entities are not real in any physical sense and are nonexistent to numberless people. Minutes and seconds are the verbal and written vestiges of an uncommon base-60 number system used in Mesopotamia millennia ago. They reside in our minds, numerical artifacts that not all humans inherit conceptually.Research on the language of numbers shows, more and more, that one of our species’key characteristics is tremendous linguistic and cognitive diversity. While there are undoubtedly cognitive commonalities across allhuman populations, our radically varied cultures foster profoundly different cognitive experiences. If we are to truly understand how much our cognitive lives differ cross-culturally, we must continually sound the depths of our species’linguistic diversity.答案Educators and business leaders have more in common than it may seem46.C)They help students acquire the skills needed for their future success.47.A)By blending them with traditional, stimulating activities.48.B) By playing with things to solve problems on their Own.49.

"Roughly 90% of nearly 170 studiesfavored the sponsor's interest," Nestle tells us via email. Other, systematic reviews support her conclusions.For instance, studies funded by Welch Foods —the brand behind Welch's 100% Grape Juice —found that drinking Concord grape juice daily may boost brain function. Another, funded by Quaker Oats, concluded, as a Daily Mail story put it, that "hot oatmeal breakfast keeps you full for longer."While these examples might induce chuckles, the past year has seen several exposes that have raised serious concerns about the extent of industry's influence on food and nutrition research outcomes.Last year, The New York Times revealed how Coca-Cola was funding high-profile scientists and organizations promoting a message that, in the battle against weight gain, people should pay more attention to exercise and less to what they eat and drink. In the aftermath of that investigation, Coca-Cola released data detailing its funding of several medical institutions and associations between 2010 and 2015, from the Academy of Family Physicians to the American Academy of Pediatrics. All told, Coca-Cola says it gave $132.8 million toward scientific research and partnerships.And earlier this summer, the Associated Press released an investigation that looked at research funded by the National Confectioners Association, a trade group whose members include the makers of Tootsie Rolls, Hershey's kisses and Snickers bars. One study the group funded concluded that kids who eat candy tend to weigh less than those who don't. In an email to her co-author, the AP reported, one of the scientists behind that study wrote that the finding was "thin and clearly padded." Nonetheless, the paper was published in a journal called Food & Nutrition Research."It's definitely a problem that so much research in nutrition and health is funded by industry," says Bonnie Liebman, director of nutrition at the Center for Science in the Public Interest, a nonprofit advocacy group. "When the food industry pays for research, it often gets what it pays for." And what it pays for is often a pro-industry finding.。

(10 points) Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and 21 worlds, while during the fifteenth century the term “reading”22 meant reading aloud. Only during the nineteenth century did silent reading become commonplace. One should be wary, however, of 23 that silent reading came about simply because reading aloud is a(n) 24 to others. Examination of factors related to the 25 development of silent reading reveals that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in 26 .The last century saw a steady gradual increase in 27 , and thus in the number of readers. As readers increased, the number of potential listeners 28 , and thus there was some 29 in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a 30 activity in such public places as libraries,railway carriages and offices, where reading aloud would 31 distraction to other readers.Towards the end of the century there was still 32 argument over whether books should be used for information or treated 33 , and over whether the reading of material such as newspapers was in some way 34 weakening. Indeed this argument remains with us still in education. 35 , its virtues, the old shared literacy culture had gone and was 36 by the printed mass media on the one hand and by books and periodicals for a 37 readership on the other.By the end of the century students were being recommended to adopt attitudes to books and to use skills in reading them which were inappropriate, 38 not impossible, for the oral reader.

that just as apparent personality can affect the personality of a child,the same is true for a cat and its owner.Owners defined as individuals with high levels of anxiety,fear,anger,depression and loneliness were more likely to have cats with behavioral issues.Such cats display more aggressive and anxious behavioral styles as well as more stress related sickness.They will also more likely to have an ongoing medical condition and be overweight.The research also found that mentally well-adjusted owners had come from happier and healthier cats.Researchers explained that many owners regard their pets as a family member and form close social bonds with them.(17)The majority of owners want to provide the best care for their pets and is therefore possible that pets could be affected by the way their owners interact with and manage them.The study highlights an important relationship between our personalities and the well-being of our pets.(18)Further research is needed to investigate the cause of nature of this relationship and look at how owners’personalities are directly influencing their pet’s behavior and well-being.It is possible that the well-being of pets is driven by the underlying nature of the owner not simply by their conscious decisions and behaviors.16.What do we learn from the new study by the University of Lincoln?17.What does the passage say most pet owners want to do?18.What does the passage say it’s still needed to understand the effects of owners’personalities on their pets?Passage Two(19)One 50-minute run can add seven hours to your life.This was a claim made by The Times last week.The claim was based on a new review of studies about the effects of running.The review concluded that an average runners live three years longer than non-runners and that running doesmore to extend life than any other form of exercise.But there’s more to running than its health benefits.(20)Research published in recent years have shown that running changes your brain and mind in some fascinating ways from increasing your brain function to regulating your emotions.However,the precise effects vary according to whether you engage in short fast running or long distance runni ng.For example,in one study,researchers compared participants’ability to learn new words after several minutes of intense running,and after 40 minutes of gentlerunning,participants were able to learn 20 percent faster after the intense running and they showed a superior memory when tested again a week later.In another study,researchers asked volunteers to jog for 30 minutes and then showed them clips from a sad movie.Participants who usually struggled to handle negative emotions were more intensely affecte d by the sad clips just as you’d expect.But crucially,this was less so if they had completed the 30 minutes jog.(21)The researchers said moderate exercise appears to have helped those participants to be less vulnerable to the impact of the sad movie.19.What did the new review of studies claim?20.What is one effect that running has on people according to recent research?21.What did another study find about the participant after they had a 30 minutes jog?Passage ThreeWelcome to the tour of the Hill House.This house built in 1904 is one of the most well-known works of Charles Hill,the famous architect.It was designed and built for local entrepreneur and his family.Before starting the tour,let me give you a brief introduction about the design of this amazing building.(23)Prior to beginning his design,the architect spends sometime in the client’s old home,observing their life and studying their habits.This meant that he could design the house according to the needs of the family.(24)The client’s main desire w as to have a home with unique design,so the architect was given complete freedom.The building style is radically different from what was the fashion of the period.At the time,most large homes were constructed of timber and brick.This one,however,is made of concrete,a novel construction material in those days.The interior of the house,including the fittings and furniture,was also designed by the same person.Most of the furniture you will see is original and in good condition.However,(25)both pieces in the ch ildren’s bedrooms are copies built to the designs of the architect.Fortunately,all the blueprints for both the building and its contents have been preserved,so we’ve been able to replace badly damaged furniture.Let’s begin our tour,starting from the rooms.22.What do we learn about the speaker?He is the guide of the tour.23.What dis the architect do before beginning his design?24.What did the architect’s client mainly want?25.What do we learn about the pieces of furniture in the children’s bedrooms?1.D)He did an unusual good deed2.C)Give some money to the waiter3.A)Whether or not to move to the state's mainland4.B)It costs too much money5.A)To investigate whether people are grateful for

transportation emerge abundantly,contributing to the fact that people*s lifestyle has been changed as well.The changes in the way of transportation can be listed as follows.First of all,with the development of technology,the price of transportation is much cheaper than before.Moreover,compared with traditional ways of buying tickets,transportation applications and websites give passengers the opportunity to book tickets online without going outside to particular ticketoffices.Besides,highspeed railways gradually replace the oldfashioned green trains,which can tremendously improve travelers’comfort during the journey and shorten the time spent on the way.
