In 2015 these ants were joined in the desert by scientists from two Belgian universities, who spent a month in the 28 heat tracking the ants and digging out their nests. The goal was simple, to discover how the 29 adapted to the kind of heat that can 30 melt the bottom of shoes.Back in Belgium, the scientists looked at the ants under an electronic microscope and found that their 31 triangular hair reflects light like a prism (棱镜), giving them a metallic reflection and protecting them from the sun’s awful heat. When Ph.D. student Quentin Willot 32 the hair from an ant with 33 knife and put it under a heat lamp, its temperature jumped.The ants’ method of staying cool is 34 among animals.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The start of high school doesn’t have to be stressful[A] This month, more than 4 million students across the nation will begin high school. Many will do well. But many will not. Consider that nearly two-thirds of students will experience the “ninth- grade shock,” which refers to a dramatic drop in a student’s academic performance. Some students cope with this shock by avoiding challenges. For instance, they may drop difficult coursework. Others may experience a hopelessness that results in failing their core classes, such as English, science and math.[B] This should matter a great deal to parents, teachers and policymakers. Ultimately it should matter to the students themselves and society at large, because students’ experience of transitioning (过渡) to the ninth grade can have long-term consequences not only for the students themselves but for their home communities. We make these observations as research psychologists who have studied how schools and families can help young people thrive.[C] In the new global economy, students who fail to finish the ninth grade with passing grades in college preparatory coursework are very unlikely to graduate on time and go on to get jobs. One study has calculated that the lifetime benefit to the local economy for a single additional student who completes high school is half a million dollars or more. This is based on higher earnings and avoided costs in health care, crime, welfare dependence and other things.[D] The consequences of doing poorly in the ninth grade can impact more than students’ ability to find a good job. It can also impact the extent to which they enjoy life. Students lose many of the friends they turned to for support when they move from the eighth to the ninth grade. One study of ninth-grade students found that 50 percent of friendships among ninth graders changed from one month to the next, signaling striking instability in friendships.[E] In addition, studies find the first year of high school typically shows one of the greatest increases in depression of any year over the lifespan. Researchers think that one explanation is that ties to friends are broken while academic demands are rising. Furthermore, most adult cases of clinical depression first emerge in adolescence (青春期). The World Health Organization reports that depression has the greatest burden of disease worldwide, in terms of the total cost of treatment and the loss of productivity.[F]Given all that’s riding on having a successful ninth grade experience, it pays to explore what can be done to meet the academic, social and emotional challenges of the transition to high school. So far, our studies have yielded one main insight: Students' beliefs about change--their beliefs about whether people are stuck one way forever, or whether people can change their personalities and abilities--are related to their ability to cope, succeed academically and maintain good mental health. Past research has called these beliefs “mindsets (思维模式),” with a “fixed mindset” referring to the belief that people cannot change and a “growth mindset” referring to the belief that people can change.[G]In one recent study, we examined 360 adolescents’ beliefs about the nature of“smartness”--that is, their fixed mindsets about intelligence.. We then assessed biological stress responses for students whose grades were dropping by examining their stress hormones(荷尔蒙).Students who believed that intelligence is fixed--that you are stuck being“not smart” if you struggle in school--showed higher levels of stress hormones when their grades were declining at the beginning of the ninth grade. If students believed that intelligence could improve -- that is to say, when they held more of a growth mindset of intelligence--they showed lower levels of stress hormones when their grades were declining. This was an exiting result because it showed that the body’s stress responses are not determined solely by one’s grades. Instead, declining grades only predicted worse stress hormones among students who believed that worsening grades were a permanent and hopeless state of affairs.[H]We also investigated the social side of the high school transition. In this study, instead of teaching students that their smartness can change, we taught them that their social standing--that is, whether they are bullied or excluded or left out - can change over time. We then looked at high school students’ stress responses to daily social difficulties. That is, we taught them a growth mindset about their social lives. In this study, students came into the laboratory and were asked to give a public speech in font of upper-year students. The topic of the speech was what makes one popular in high school. Following this, students had to complete a difficult mental math task in front of the same upper-year students.[I]Experiment results showed that students who were not taught that people can change showed poor stress responses. When these students gave the speech, their blood vessels contracted and their hearts pumped less blood through the body -- both responses that the body shows when it is preparing for damage or defeat after a physical threat. Then they gave worse speeches and made more mistakes in math. But when students were taught that people can change, they had better responses to stress, in part because they felt like they had the resources to deal with the demanding situation. Students who got the growth mindset intervention (干预) showed less-contracted blood vessels and their hearts pumped more blood- both of which contributed to more oxygen getting to the brain, and, ultimately, better performance on the speech and mental math tasks.[J]These findings lead to several possibilities that we are investigating further. First, we are working to replicate (复制) these findings in more diverse school communities. We want to know in which types of schools and for which kinds of students these growth mindset ideas help young people adapt to the challenges of high school. We also hope to learn how teachers, parents or school counselors can help students keep their ongoing academic or social difficulties in perspective. We wonder what would happen if schools helped to make beliefs about the potential for change and improvement a larger feature of the overall school culture, especially for students staring the ninth grade.36. The number of people experiencing depression shows a sharp increase in the first year of high school.37. According to one study, students’ academic performance is not the only decisive factor of their stress responses.38. Researchers would like to explore further how parents and schools can help ninth graders by changing their mindset.39. According to one study, each high school graduate contributes at least 500,000 dollars to the local economy.，40. In one study, students were told their social position in school is not unchangeable.41. It is reported that depression results in enormous economic losses worldwide.42. One study showed that friendships among ninth graders were far from stable.43. More than half of students will find their academic performance declining sharply when they enter the ninth grade.44. Researchers found through experiments that students could be taught to respond to stress in more positive way.45. It is beneficial to explore ways to cope with the challenges facing students entering high school.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.Educators and business leaders have more in common than it may seem. Teachers want to prepare students for a successful future. Technology companies have an interest in developing a workforce with the STEM (science, technology, engineering and math) sills needed to grow the company and advance the industry. How can they wok together to achieve these goals? Play may be the answer.Focusing on STEM skills is important, but the reality is that STEM sills are enhanced and more relevant when combined with traditional, hands-on creative activities. This combination is proving to be the best way to prepare today’s children to be the makers and builders of tomorrow. That is why technology companies are partnering with educators to bring back good, old-fashioned play.In fact many experts argue that the most important 2lst-century skills aren’t related to specific technologies or subject matter, but to creativity; skills like imagination, problem-finding and problem-solving, teamwork, optimism, patience and the ability to experiment and take risks. These are skills acquired when kids tinker (鼓捣小玩意), High-tech industries such as NASA’s Jet Propulsion Laboratory have found that their best overall problem solvers were master tinkerers in their youth.There are cognitive (认知的) benefits of doing things the way we did as children—building something, tearing it down, then building, it up again. Research shows that given 15 minutes of free pay, four- and five-year-olds will spend a hid of this time engaged in spatial, mathematical，and architectural activities. This type of play—especial with building blocks--helps children discover and develop key principles in math and geometry.If play and building are critical 1o 2lst century skill development, that’s really good news for two reasons: Children are born builders, makers, and creators, so fostering(培养) 2lst-centary skills may be as simple as giving kids room to play, tinker and try thing out,even as they growolder, Secondly, it doesn't take 21st-century technology to foster 2lst-century skills. This is especially important for under-resourced schools and communities. Taking whatever materials are handy and tinkering with them is a simple way to engage those important “maker” skills. And anyone, anywhere. can do it.46. What docs the author say about educators?A) They seek advice from technology companies to achieve teaching goals.B) They have been successful in preparing the workforce for companies.C) They help students acquire the skills needed for their future success.D) They partner with technology companies to enhance teaching efficiency.47. How can educators better develop students’ STEM skills, according to the author?A) By blending them with traditional, stimulating activities.B) By inviting business leaders to help design curriculums.C) By enhancing students’ ability to think in a critical way.D) By showing students the best way to learn is through play.48. How do children acquire the skills needed for the 21st century?A) By engaging in activities involving specific technologies.B) By playing with things to solve problems on their own.C) By familiarizing themselves with high-tech gadgets.D) By mastering basic principles through teamwork.49. What can we do to help children learn the basics of math and geometry?A) Stimulate their interest as early as possible.B) Spend more time playing games with them.C) Encourage them to make things with hands.D) Allow them to tinker freely with calculators.50. What does the author advise disadvantaged schools and communities to do?A) Train students to be makers to meet future market demands.B) Develop students’ creative skills with the resources available.C) Engage students with challenging tasks to foster their creativity.D) Work together with companies to improve their teaching facilities.Passage TwoQuestions 51 to 55 are based on the following passage.Being an information technology, or IT, worker is not a job I envy. They are the ones who, right in the middle of a critical meeting, are expected to instantly fix the projector that’s no longer working. They have to tolerate the bad tempers of colleagues frustrated at the number of times they've had to call the help desk for the same issue. They are also the ones who know there are systems that are more powerful, reliable and faster, but their employer simply will not put up the funds to buy them.According to a recent survey, employees who have a job reliant on IT support consider IT a major source of job dissatisfaction. Through no fault of they own, they can suddenly find their productivity deteriorating or quality control non-existent. And there’s little they can do about it.The experience of using IT penetrates almost the entire work field. It has become a crucial part of employees’ overall work experience. When IT is operating as it should, employee self-confidence swells. Their job satisfaction, too, can surge when well-functioning machines relieve them of dull tasks or repetitive processes. But if there’s one thing that triggers widespread employee frustration, it’s an IT transformation project gone wrong, where swollen expectations have been popped and a long list of promised efficiencies have been reversed.This occurs when business leaders implement IT initiatives with little consideration of how those changes will impact the end user.Which is why managers should appreciate just how influential the IT user experience is to their employees, and exert substantial effort in ensuring their IT team eliminates programming errors and application crashes. Adequate and timely IT support should also be available to enable users to cope with technological issues at work. More importantly, IT practitioners need to understand what employees experience mentally when hey use IT.Therefore, businesses need to set up their IT infrastructure so that it is designed to fit in with their employees’ work, rather than adjust their wok to fit in with the company’s IT limitations.51. What does the author say about working in IT?A)It is envied by many.B) It does not appeal to him.C It is financially rewarding.D) It does not match his abilities.52. What is the finding of a recent survey on employees who have a job reliant on IT support?A) IT helps boost productivity.B) IT helps improve quality control.C) Many employees are deeply frustrated by IT.D) Most employees rely heavily on IT in their work.53. What is said to happen when IT is functioning properly?A) There is a big boost in employees’ work efficiency.B) Employees become more dependent on machines.C) There are no longer any boring or repetitive tasks.D) Employees become more confident in their work.54. What should business leaders do before implementing new IT initiatives?A) Consider the various expectations of their customers.B) Draw up a list of the efficiencies to be promised.C) Assess the swollen cost of training the employees.D) Think about the possible effects on their employees.55. How can a business help improve its employees' experience in using IT?A) By designing systems that suit their needs.B) By ensuring that their mental health is sound.C) By adjusting their work to suit the 1T system.D) By offering them regular in-service training.Part Ⅳ Translation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Despite the excellent work and deep 40 of our nation's teachers and principals, students in high-poverty, high- minority schools are unfairly treated across our country.We have to do better.Local leaders and educators will 41 their own creative solutions, but we must work together to 42 our focus on how to better recruit, support and 43 effective teachers and principals for all students, especially the kids who need them most."Today's announcement is another important step forward in improving access to a quality education, a 44 of President Obama's year of ter today, Secretary Duncan will lead a roundtable discussion with principals and school teachers from across the country about the 45 of working in high-need schools and how to adopt promising practices for supporting great educators in these schools.A.AnnouncingB.beneficialC.challengesmitmentponentF.contestsG.criticallyH.developI.distributingJ.enhanceK.entitledL.potentialM.properlyN.qualifiedO.retainSection BDirections: In this section, you are going to read a passage with ten statements attached to it.Eachstatement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.The Changes Facing Fast FoodA.Fast-food firms have to be a thick-skinned bunch.Health experts regularly criticise them severelyfor selling food that makes people fat.Critics even complain that McDonald's, whose logosymbolises calorie excess, should not have been allowed to sponsor the World Cup.These arethings fast-food firms have learnt to cope with.But not perhaps for much longer.The burgerbusiness faces more pressure from regulators at a time when it is already adapting strategies inresponse to shifts in the global economy.B)Fast food was once thought to be recession-proof.When consumers need to cut spending, the logicgoes, cheap meals like Big Macs and Whoppers become even more attractive.Such "trading down"proved true for much of the latest recession, when fast-food companies picked up customers who could no longer afford to eat at casual restaurants.Traffic was boosted in America, the home of fast food, with discounts and promotions, such as $1 menus and cheap combination meals.C)As a result, fast-food chains have weathered the recession better than their more expensive competitors.In 2020 sales at full-service restaurants in America fell by more than 6% , but total sales remained about thesame at fast-food chains.In some markets, such as Japan, France and Britain, total spending on fast food increased.Same-store sales in America at McDonald's, the world's largest fast-food company, did not decline throughout the downturn.Panera Bread, an American fast-food chain known for its fresh ingredients, performed well, too, because it offers higher-quality food at lower prices than restaurants.D)But not all fast-food companies have been as fortunate.Many, such as Burger King, have seen sales fall.In a severe recession, while some people trade down to fast food, many others eat at home more frequently to save money.David Palmer, an analyst at UBS, a bank, says smaller fast- food chains in America, such as Jack in the Box and Carl's Jr., have been hit particularly hard in this downturn because they are competing with the global giant McDonald's, which increased spending on advertising by more than 7% last year as others cut back.E.Some fast-food companies also sacrificed their own profits by trying to give customers better value.During the recession companies set prices low, hoping that once they had tempted customers through the door they would be persuaded to order more expensive items.But in many cases that strategy did not st year Burger King franchisees (特许经营人)sued (起诉)the company over its double-cheeseburgerpromotion, claiming it was unfair for them to be repuired to sell these for $1 when they cost$1.10 to make.In May a judge ruled in favour of Burger King.Nevertheless, the company may still be cursing its decision to promote cheap choices over more expensive ones because items on its "value menu" now account for around 20% of all sales, upfrom 12% last October.F.Analysts expect the fast-food industry to grow modestly this year.But the downturn is makingcompanies rethink their strategies.Many are now introducing higher-priced items to entice (引诱)consumers away from $1 specials.KFC, a division of Yum! Brands, which also owns Taco Belland Pizza Hut, has launched a chicken sandwich that costs around $5.And in May Burger Kingintroduced barbecue (烧烤)pork ribs at $7 for eight.panies are also trying to get customers to buy new and more items, including drinks.McDonald's started selling better coffee as a challenge to Starbucks.Its " McCafe" line nowaccounts for an estimated 6% of sales in America.Starbucks has sold rights to its Seattle's Bestcoffee brand to Burger King, which will start selling it later this year.H.As fast-food companies shift from "super size" to "more buys", they need to keep customer traffichigh throughout the day.Many see breakfast as a big opporttmity, and not just for fatty food.McDonald's willstart selling porridge (粥)in America next year.Breakfast has the potential to bevery profitable, says Sara Senatore of Bernstein, a research firm, because the margins can be high.Fast-food companies are also adding midday and late-night snacks, such as blended drinks andwraps.The idea is that by having a greater range of things on the menu, "we can sell to consumersproducts they want all day," says Rick Carucci., the .chief financial officer of Yum ! Brands.I.But what about those growing waistlines? So far, fast-food firms have cleverly avoided governmentregulation.By providing healthy options, like salads and low-calorie sandwiches, they have at leastgiven the impression of doing something about helping to fight obesity (肥胖症).These offeringsare not necessarily loss-leaders, as they broaden the appeal of outlets to groups of diners thatinclude some people who don't want to eat a burger.But customers cannot be forced to ordersalads instead of fries.J.In the future, simply offering a healthy option may not be good enough."Every packaged-food and restaurant company I know is concerned about regulation right now," says Mr.Palmer of UBS.America's health-reform bill, which Congress passed this year, requires restaurant chains with 20 ormore outlets to put the calorie-content of items theyserve on the menu.A study by the NationalBureau of Economic Research, which tracked the effects on Starbucks of a similar calorie-postinglaw in New York City in 2007, found that the average calorie-count per transaction fell 6% andrevenue increased 3% at Starbucks stores where a Dunldn Donuts outlet was nearby--a sign, it issaid, that menu-labelling could favour chains that have more healthy offerings.K.In order to avoid other legislation in America and elsewhere, fast-food companies will have tocontinue innovating (创新).Walt Riker of McDonald's claims the change it has made in its menumeans it offers more healthy items than it did a few years ago."We probably sell more vegetables,more milk, more salads, more apples than any restaurant business in the world," he says.But therecent proposal by a county in California to ban McDonald's from including toys in its high-calorie"Happy Meals", because legislators believe it attracts children to unhealthy food, suggests there isa lot more left to do.46.Some people propose laws be made to stop McDonald's from attaching toys to its food specials for children.47.Fast-food finns may not be able to cope with pressures from food regulation in the near future.48.Burger King will start to sell Seattle's Best coffee to increase sales.49.Some fast-food firms provide healthy food to give the impression they are helping to tackle the obesity problem.50.During the recession, many customers turned to fast food to save money.51.Many people eat out less often to save money in times of recession.52.During the recession, Burger King's promotional strategy of offering low-priced items often proved ineffective.53.Fast-food restaurants can make a lot of money by selling breakfast.54.Many fast-food companies now expect to increase their revenue by introducing higher-priced items.55.A newly-passed law asks big fast-food chains to specify the calorie count of what they serve on the menu.Section CDirections: There are 2 passages in this section.Each passage is followed by some questions orunfinished statements.For each of them there are four choices marked A., B), C.andD ).You should decide on the best choice and mark the corresponding letter on AnswerSheet 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on the following passage.If you think a high-factor sunscreen (防晒霜)keeps you safe from harmful rays, you may be wrong.Research in this week's Nature shows that while factor 50 reduces the number of melanomas(黑瘤)and delays their occurrence, it can't prevent them.Melanomas are the most aggressive skin cancers.You have a higher risk if you have red or blond hair, fair skin, blue or green eyes, or sunburn easily, or if a close relative has had one.Melanomas are more common if you have periodic intense exposure to the sun.Other skin cancers are increasingly likely with long-term exposure.There is continuing debate as to how effective sunscreen is in reducing melanomas the evidence is weaker than it is for preventing other types of skin cancer.A 2020 Australian study of 1,621 people found that people randomly selected to apply sunscreen daily had half the rate of melanomas of people who used cream as needed.A second study, comparing 1,167 people with melanomas to 1,101 who didn't have the cancer, found that using sunscreen routinely, alongside other protection such as hats,long sleeves or staying in the shade, did give some protection.This study said other forms of sun protection not sunscreen seemed most beneficial.The study relied on people remembering what they had done over each decade of their lives, so it's not entirelyreliable.But it seems reasonable to think sunscreen gives people a false sense of security in the sun.Many people also don't use sunscreen properly applying insufficient amounts, failing to reapply after a couple of hours and staying in the sun too long.It is sunburn that is most worrying recent research shows five episodes of sunburn in the teenage years increases the risk of all skin cancers.The good news is that a combination of sunscreen and covering up can reduce melanoma rates, as shown by Australian figures from their slip-slop-slap campaign.So if there is a heat wave this summer, it would be best for us, too, to slip on a shirt, slop on (抹上)sunscreen and slap ona hat.56.What is people's common expectation of a high-factor sunscreen?A.It will delay the occurrence of skin cancer.B.It will protect them from sunburn.C.It will keep their skin smooth and fair.D.It will work for people of any skin color.57.What does the research in Nature say about a high-factor sunscreen?A.It is ineffective in preventing melanomas.B.It is ineffective in case of intense sunlight.C.It is ineffective with long-term exposure.D.It is ineffective for people with fair skin.58.What do we learn from the 2020 Australian study of 1,621 people?A.Sunscreen should be applied alongside other protection measures.B.High-risk people benefit the most from the application of sunscreen.C.Irregular application of sunscreen does women more harm than good.D.Daily application of sunscreen helps reduce the incidence of melanomas.59.What does the author say about the second Australian study?A.It misleads people to rely on sunscreen for protection.B.It helps people to select the most effective sunscreen.C.It is not based on direct observation of the subjects.D.It confirms the results of the first Australian study.60.What does the author suggest to reduce melanoma rates?ing both covering up and sunscreen.B.Staying in the shade whenever possible.ing covering up instead of sunscreen.D.Applying the right amount of sunscreen.Passage TwoQuestions 61 to 65 are based on the following passage.Across the rich world, well-educated people increasingly work longer than the less-skilled.Some65% of American men aged 62 -74 with a professional degree are in the workforce, compared with32% of men with only a high-school certificate.This gap is part of a deepening divide between the well-educated well-off and the unskilled poor.Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled.The consequences, for individuals and society, are profound.The world is facing an astonishing rise in the number of old people, and they will live longer than ever before.Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion.The experience of the 20th century, when greater longevity (长寿)translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled.Employment rates are falling among younger unskilled people, whereas older skilled folk are working longer.The divide is most extremein America, where well-educated baby-boomers (二战后生育高峰期出生的美国人)are putting off retirement while many less-skilled younger people have dropped out of the workforce.Policy is partly responsible.Many European governments have abandoned policies that used to encourage people to retire early.Rising life expectancy (预期寿命), combined with the replacement of generous defmed-benefit pension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement.But the changing nature of work also plays a big role.Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than the preceding generation.Technological change may well reinforce that shift: the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.61.What is happening in the workforce in rich countries?A.Younger people are replacing the elderly.B.Well-educated people tend to work longer.C.Unemployment rates are rising year after year.D.People with no college degree do not easily find work.62.What has helped deepen the divide between the well-off and the poor?A.Longer life expectancies.B.A rapid technological advance.C.Profound changes in the workforce.D.A growing number of the well-educated.63.What do many observers predict in view of the experience of the 20th century?A.Economic growth will slow down.ernment budgets will increase.C.More people will try to pursue higher education.D.There will be more competition in the job market.64.What is the result of policy changes in European countries?A.Unskilled workers may choose to retire early.B.More people have to receive in-service training.C.Even wealthy people must work longer to live comfortably in retirement.D.People may be able to enjoy generous defined-benefits from pension plans.65.What is characteristic of work in the 21st century?puters will do more complicated work.B.More will be taken by the educated young.C.Most jobs to be done will be the creative ones.D.Skills are highly valued regardless of age.Part ⅣTranslation ( 30 minutes)Directions: For this part, you are

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.

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.

said of their ability to dominate the corporate boardroom、 And according to a new Pew Research Center survey on women and leadership, most Americans find women indistinguishable from men on key leadership traits such as intelligence and capacity for innovation, with many saying theyre stronger than men in terms of being passionate and organized leaders、So why, then, are women in short supply at the top of government and business in the United States? According to the public, at least, its not that they lack toughness, management talent or proper skill sets、Its also not all about work-life balance、Although economic research and previous survey findings have shown that career interruptions related to motherhood may make it harder for women to advance in their careers and pete for top executive jobs, relatively few adults in the recent survey point to this as a keybarrier for women seeking leadership roles、 Only about one-in-five say womens family responsibilities are a major reason why there aren’t more females in top leadership positions in business and politics、Instead, topping the list of reasons, about four-in-ten Americans point to a double standard for women seeking to climb to the highest levels of either politics or business, where they have to do more than their male counterparts to prove themselves、 Similar shares say the electorate(选民)and corporate America are just not ready to put more women in top leadership positions、As a result, the public is divided about whether the imbalance in corporate America will change in the foreseeable future, even though women have made major advances in the workplace、 While53% believe men will continue to hold more top executive positions in business in thefuture,44% say its only a matter of time before as many women are in top executive positions as men、 Americans are less doubtful when it es to politics:73% expect to see a female president in their lifetime、47、【题干】What do most Americans think of women leaders according to a new Pew Research Center survey?【选项】A、They have to do more to distinguish themselves、B、They have to strive harder to win their positions、C、They are stronger than men in terms of willpower、D、They are just as intelligent and innovative as men、48、【题干】What do we learn from previous survey findings about women seeking leadership roles?【选项】A、They have unconquerable difficulties on their way to success、B、They are lacking in confidence when peting with men、C、Their failures may have something to do with family duties、D、Relatively few are hindered in their career advancement、49、【题干】What is the primary factor keeping women from taking top leadership positions according to the recent survey?【选项】A、Personality traits、B、Family responsibilities、C、Gender bias、D、Lack of vacancies、50、【题干】What does the passage say about corporate America in the near future?【选项】A、More and more women will sit in the boardroom、B、Gender imbalance in leadership is likely to change、C、The public is undecided about whether women will make good leaders、D、People have opposing opinions as to whether it will have more women leaders、51、【题干】What do most Americans expect to see soon on Americas political stage?【选项】A、A woman in the highest position of government、B、More and more women actively engaged in politics、C、A majority of women voting for a female president、D、As many women in top government positions as men、Passage TwoQuestions52 to56 are based on the following passage、People have grown taller over the last century, with South Korean women shooting up by more than20cm on average, and Iranian men gaining、16、5cm、 A global study looked at the average height of18-year-olds in200 countries1914 and全文结束》》、The results reveal that while Swedes were the tallest people in the world in1914, Dutch men have risen from12th place to claim top spot with an average height of182、5cm、 Larvian women、 Meanwhile, rose from28th place in1914 to bee the tallest in the world a century later, with an average height of169、8cm、James Bentham, a co-author of the research from Imperial College, London, says the global trend is likely to be due primarily to improvements in nutrition and healthcare、"An individual’s geics has a big influence on their height, but once you average over whole populations, geics plays a less key role," he added、A little extra height brings a number of advantages, says Elio Riboli of Imperial College、 "Being taller is associated with longer life expectancy," he said、 "This is largely due to a lower risk of dying of cardiova。

2020年12月英语四级真题及参考答案-三套全四级写作第一套Directions: For this part, you are allowed 30 minutes to write an essay on the change of communication. You should write at least 120 words but no more than 180 words.With the development of science and technology, we have witnessed the various huge changes of our daily life, among which, the change of communication is striking. However, people’s view on it never come to consensus. Concerning it, both communication online and offline have their merits.For one thing, no one denies that communication online brings great convenience to us, especially to those who have friends or relatives in remote areas. Because the change makes it possible for them to have frequent chat. And, the way we contact with others is diverse. Video calls and voice message can both meet modern people’s satisfaction. For another, the change is also making us disconnected. Due to the availability, people are gradually reluctant to have face-to-face communication with surrounding people, which is isolating us from the people we love.Given the factors above, the change of communication, we have to admit, is more like a double-edged sword. Neither do we discard it nor completely rely on it. Instead, we should make reasonable use of it so as to maximize its benefits.随着科学技术的发展，我们见证了我们日常生活中的各种巨大变化，其中沟通方式的变化是引人注目的。

It could alsomean training employees how to do their jobs through video game platforms. Companies fromGoogle to L'Oréalto IBM to Wells Fargo are known to use some degree of gamification in theirworkplaces. And more and more companies are joining them. A recent report suggests that theglobal gamification market will grow from $1.65 billion in 2021 to $11.1 billion by 2021.D) The concept of gamification is not entirely new, Werbach says. Companies, marketers and teachershave long looked for fun ways to engage people's reward-seeking or competitive spirits.

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

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

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. From my perspective,the changes in the way of transportation mainly lie in the good respects.As one of the fortunate passengers who live in the age of internet and can get access to online service of transportation,I can*t help exclaiming:it is the best of times.六、翻译部分：春节前夕吃团圆饭是中国人的传统。
