Although researchers have long known that the rich live longer than the poor, this education gap is less well documented. And although the average American’s expected span(预期寿命) has been smooth in recent year—and, shockingly, even fell between 2015 and 2017—that of the one-third with a bachelor’s degree has continued to lengthen.This gap in life expectancy is growing, according to new research published in the report of the National Academy of Sciences. Anne Case and Angus Deation ofPrincetonUniversityfound that the lifespans of those with and without a bachelor’s degree started to become different in the 1990s and 2000s. This gap grew even wider in the 2010s.What is the link between schooling and longevity(长寿)? Some argue that better-educated people develop healthier lifestyles: each additional year of study reduces the chances of being a smoker and of being overweight. The better-educated earn more, which in turn is associated with greaterhealth.Ms Case and Mr Deaton argue that changes in labor markets, including the rise of automation and increased demand for highly-educated workers, coupled with the rising costs of employer-provided health care, have decreased the supply of well-paid jobs for those without a degree. This may be contributing to higher rates of alcohol and drug use, suicide and other “deaths of despair”.The authors argued that the educational gap in mortality(致死率) will widenin the wake ofthe covid-19 pandemic. ForAmerica’s overall life expectancy to start climbing again, improvements will be needed across all social groups, not just among the privileged few.4. When did the lifespans of people with and without a degree vary greatly?A. In the 1990s.B. In the 2020sC. In the 2000sD. In the 2010s5.

The gap in life expectancy.C. Raised request for better-educated workers.D. The development of automation.6. What does the underlined phrase “in the wake of” probably mean ?A. afterB. untilC. beforeD. while7. What is the best title for the text?A. Changes in labor market.B. Quit bad habits by Further studyC. Educated Americans live longer.D. Highly-educated people develop healthier lifestyles.CShanghairesidents passing through the city’s eastern Huangpu district in Octobermight have astonished at an unusual sight: a “walking” building. An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors help control how the building moves forward.TheLagenaPrimary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used inShanghaito relocate a historical building.In recent years,China’s rapid modernization has seen many historic buildingsrazedto clear land for skyscrapers and office buildings. But there has been growing concern about the architectural heritage loss as a result of destruction across the country.Shanghaihas beenChina’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life. The city also has a track record of relocating old buildings. In 2018, the city relocated a 90-year-old building in Hongkou district, which was then considered to beShanghai’s most complex relocation project to date.8. How did the primary school get moved?A. By reducing the weight of it.B. By using movable supports.C. By dividing it into several parts.D. By using robotic legs.9. What does the underlined word “razed” probably mean in Paragraph 5?A. Replaced.B. Burnt.C. Protected.D. Destroyed.10. What can we infer about the heritage preservation inChina?A. The use of advanced technology leads to growing concern.B. Shanghai is the pioneer in preserving architectural heritage.C.A number of old buildings have been given new life.D. Many historic buildings will be relocated.11. What is the passage mainly about?A. New preservation campaigns are launched inChina.B. New technology gives new life to historic buildings.C. A building inShanghai“walks” to a new location.D. “Walking machine” makes heritage protection simpler.DMy school appeared on the news last week because we had made an important change in our local area. Our class had planted a large garden in what was once only a vacant lot. It was a lot of work but it was all worth it. I got blisters(水泡) from digging, and we all got insect bites, too.I learned a lot about gardening and collaboration(合作), and then I learned about the media. Our teacher telephoned the TV station and informed them of what we had accomplished. She spoke with the producer. The producer checked with the directors, but they said there were plenty of stories similar to ours. They wanted to know what was special about our particular garden, since many schools plant them.The teacher explained that, after going on the Internet to learn about the prairie(大草原), we had made a prairie garden. We had gone to a prairie and gotten seeds from the plants, and then we planted them. We did not water the garden, but we did weed it. We decided to let nature water it with rain, since that was how prairiesgrew in the past. We sent a picture of the garden to the news station. In the picture, the grass was so high that it stood taller than the fourth grade students.As a result, the producer sent a reporter to our school. He interviewed the headmaster and asked him many questions about the garden. After that, they interviewed us, and we explained to them what we had learned through this project.That night, we watched the news, and there we were. The news reporter told our story. It was only two minutes long, but it was us. We were famous. All that work, all those blisters, it was worth it. We knewthatwhen we saw the garden every day, but now we knew that the whole city thought so, too.12. What seemed to be the TV directors’ initial reaction to the garden?A. They were excited.B. They were surprised.C. They were worried.D. They were uninterested.13. What is special about the garden?A. Weeds were allowed to spread naturally.B. The grass grew faster than common grass.C. The seeds came from the plants of a prairie.D. Underground water was used for the plants.14. What does the underlined word “that” refer to in the last paragraph?A. We got blisters on our hands.B. Our hard work was worthwhile.C. The garden would be famous.D. The project would be finished.15. How did the author feel about the project?A. Annoyed.B. Curious.C. Proud.D. Regretful.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
2019-2020学年昆明学校高三英语一模试题及答案
2019-2020学年昆明学校高三英语一模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AMy Biggest ChallengeAs a writer on an adventure sports magazine, I’dalways fought shy of doing the adventurous stuff myself, preferring instead to observe the experts from a safe distance and relay their experiences to readers in the form of written language. Thus, when I was challenged to take part in a mountain climb in aid of raising money for charity-and to write about it afterwards-I was unwilling, to say the least.I was lucky enough to have a brilliant climbing coach called Keith, who put me through my paces after my daily work. He gave me knowledge about everything from the importance of building muscle groups to how to avoid tiredness through nutrition. It quickly became apparent that the mechanics of climbing were more complex than I had imagined. There was the equipment and techniques I’d never even heard of, all of which would come in handy on the snow-capped peak I’d be climbing.Aware of the challenge, Keith made a detailed action plan and I forced myself to stick to it, doing a daily workout at the gym and going on hikes with a heavy pack. I perfected my technique on the climbing wall and even went to climb the mountains to get vital experience. My self-belief increased alongside my muscle power and I became confident about finishing the climb.All too soon I was on a plane to my destination. On that day, when I looked up at the mountain, I thought of abandoning it. But then I remembered all the hard work I’d done and how disappointed Keith would be if I gave up at the last minute-not to mention letting down the charity and the sense of failure I’d experience myself. With a deep breath I gathered my equipment and headed out into the sunshine to meet the rest of the group.And as I sit here now, tapping away on my laptop, I’m amazed at the details in which I can recall every second of the climb: the burning muscles, the tiredness, the minor problems along the way. Could I have been better prepared? Possibly. Would I be back for another go? Thankfully not. The feeling of being excited when I stood on top of the world is a never-to-be-repeated experience but one I will enjoy forever nevertheless.1. At the beginning of the activity, the author revealed his ______.A. disappointment in the coming adventure.B. expectation of writing about his experience.C. lack of enthusiasm for the challenge he’d been offered.D. curiosity about taking part in the mountain climb for charity.2. What did the author realise during his climb training?A. The knowledge about climbing was really confusing.B. The equipment was the key factor to reach the peak.C. Climbing was much more complicated than expected.D. Hard training was far more important than making plans.3. How did the author feel after he succeeded in climbing the mountain?A. He was relieved that he wouldn’t have to do it again.B. He was well satisfied that he had done his best for it.C. He was surprised that he had managed to complete it.D.He was regretful that it wasn’t as smooth as imagined.BSummer heat can be dangerous, and heat leads to tragedy far toooften. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch (草图) of a device he called “Oasis.”The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry alsodesigns the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of this technology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’ potential that they have raised more than twice that — over $46,000.Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of a solution,” he said. “We always just complain about things and rarely offer solutions.”4. What inspired Curry to invent Oasis?A. His narrow escape from death after being locked in a car.B. His knowledge of many children’s death because of car heat.C. The death of his neighbor’s baby after being left in a hot car.D. The injury of 37 children in his school in a car accident.5. What would Oasis do if it was hot in a car with a child?A. It would inform the parents or even the police.B. It would pump out the hot air in the car.C. It would sound the alarm attached to the car.D. It would get the window open to save the child.6. What does Curry’s father think is cool about Curry’s invention?A. It used some of the most advanced technology.B. It simply combined technologies that existed.C. It could accelerate production of new technology.D. It is the most advanced among similar products.7. Why did Curry’s father start a campaign to raise money?A. To conduct experiments to test the invention.B. To get other children devoted to inventions.C. To support a charity of medical aid for children.D. To get the patent and bring it to production.CThe COVID-19 vaccination（接种疫苗）rate in the US has fallen to newlows in recent weeks, threatening President Joe Biden’s goal of having 70 percent of American adults with at least one shot by July 4.With just less than one month from July 4, the current vaccination rate will put the US at somewhere between 67 percent and 68 percent of the adult population with at least one dose（剂量）by Independence Day. To reach 70 percent by July 4, around 1.6 percent of the population needs to get their first dose per week from now until July 4.The Centers for Disease Control and Prevention（CDC）reported last week that 63 percent of adultshadreceived their first dose of a COVID-19 vaccine. That was up slightly from 62 percent from the report a week before. The additional 1 percent of adults completing their first dose is the lowest since the CDC started tracking the vaccination rate in mid-February.On average, fewer than 1 million shots are given out per day, a decline of more than two-thirds from the peak of 3.4 million in April, The Washington Post reported. In South Carolina, about 71,000 residents got a shot in the week leading up to June 3, compared to a high of nearly 300,000 in one week in early April, according to data from the CDC.The slowdown is moreprominentacross the South and Midwest. Twelve states have seen vaccinations fall to 15 daily shots per 10,000 residents. Less than a quarter of black Americans had received their first COVID-19 shot as of June 7.James Hildreth, CEO of Meharry Medical College, told Politico, “We need to make a stronger effort to bring the vaccine to the communities, rather than relying on the communities to come to vaccination centers.”The sharp decline in vaccination began in mid-April when federal officials temporarily stopped the use of the Johnson＆Johnson vaccine while they investigated rare blood-clotting（凝血）reactions.The “low-hanging fruit—thosepeople who ly want to get vaccinated without you telling them anything” have already been vaccinated, which has led to the slowdown, Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said on a White House-organized call with community leaders last week, according to the Post.8. What can we learn from the text?A. Dr Anthony Fauci is in charge of the Centers for Disease Control and Prevention.B. In South Carolina, about 300,000 residents got a shot in the week leading up to June 3C. In mid-April federal officials temporarily suspended the Johnson＆Johnson vaccine.D. Less than one fourth of Americans had received their first COVID-19 shot by June 7.9. Which of the following can replace the underlined word “prominent” in Para. 5?A. Meaningful.B. Obvious.C. Inspiring.D. Complex.10. How can America increase the COVID-19 vaccination rate according to James Hildreth?A. By giving the vaccine shot at the communities.B. By offering the vaccine to the public for free.C. By frequently informing the public of the vaccine.D. By urging the communities to come to vaccination centers.11. What can be the best title for the text?A. Biden wishes to have 70% of adults with one shot by July 4B. CDC has been trackingthe vaccination rate since mid-FebruaryC. Some Americans need to get vaccinated without telling them toD. Biden’s July 4th vaccine goal may be missedDAccording to statistics published by the BPI (Buying Power Index) a couple of months ago, digital streaming (流媒体) now accounts for 80 percent of the music consumption in the UK. Despite the incredible growth of online streaming platforms like iTunes, Apple Music and Tidal over the past 15 years, a more traditional medium has also seen a return of interest and sales in the music industry. In 2020, almost one in five of all albums purchased in the UK is vinyl (黑胶唱片), and it has once again become the most popular physical musical medium.With digital streaming so easy and convenient, why are so many peopledrawn to traditional records? Some experts claim that vinyl is a physical medium for experiencing music, something tangible (有形的) to hold and own. For most people, having something tangible and interacting with it gives depth to the experience of music. Listening to an album and touching it the way the artist intended can make them feel more connected to the music and the artist. Records are physical products that can be not only displayed but also gifted, shared, traded and passed down through generations.Sound quality is another hot topic. A lot of music lovers feel that the analogue sound (模拟声音) vinyl offers is superior to modern digital audio, particularly with regards to the compressed formats streaming platforms use. There’s a common belief that old-school analogue audio has a warmer, fuller sound than digitised music. For vinyl followers, the very defect traditional recorders often have, such as the familiar crackle (劈啪作响) when the record starts, bring the music to life in a different way.There’s aritualisticaspect to vinyl that a lot of people are drawn to, too. The act of putting a record on—carefully removing the record from the sleeve, placing it on the record player and gently dropping the needle on the right groove (凹槽)—is a more assiduous (一丝不苟的), mindful way of engaging with music. When you’re listening to vinyl, you can’t tap abutton and go about your day while the streaming service provides hours of music. You need to stay close to the record player to move the needle and flip the record over.It’s clear that the vinyl interest is well underway, and vinyl records are truly making a comeback. In an increasingly digital society, there’s something to be said for analogue experiences. Perhaps one of the great things about being alive in the 21st century is our ability to have the best of both worlds—the timeless appeal of physicalrecords alongside the easy access to vast music libraries that streaming offers.12. What are the statistics published by the BPI used to show?A. An increase in music consumption.B. The recovery of music industry.C. A comeback of a physical medium.D. The acceptance of online streaming.13. According to some experts, why does vinyl interest many people?A. It attracts people by its realistic feel.B. It offers simple access to different music.C. It shares a new way to enjoy music.D. It provides people with perfect sound effect.14. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B. Updated very frequently.C. Performed as part of a ceremony.D. Kept for a long time without changing.15. How does the writer feel about the future development of music medium?A. Traditional records will get underway.B. The analogue experiences may matter more.C. Vinyl sales will boom with technological advance.D. There should be a good mix of old and new.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成下面小题。
这几天，知名视频博主李子柒，因在境外视频网站上拥有超高人气和关注度，再次引发人们的讨论。
有文章认为，这位博主主打传播中国传统美食文化，通过镜头语言呈现田园生活，令外国网友喜爱并评价说“她在重新向全世界介绍，被我们忘记的那些中国文化、艺术和智慧。
”从这个角度而言，李子柒的作品具有文化输出的意义。
当然，这一结论也引发了不小争议。
浏览李子柒微博的主页，不难发现这位拥有两千万粉丝的大V与众不同之处。
在她更新频率不算高的视频中，能够看到黄豆如何变成酱油、纯手工造纸等等传统文化遗产，也能读到蕴藏于田园生活背后的脉脉温情，这些满足了现代都市人对于田园牧歌的向往，也打开了西方世界欣赏中国文化的一个窗口。
由此而言，李子柒的走红不难理解。
但能不能把这种走红视作文化输出，以及中国需不需要这样的输出，在网上言人人殊。
有人认为李子柒的视频不真实，拔高了现实生活；也有人认为乡土社会代表不了中国全貌，会带来误解；还有人质疑其包装炒作的成分，担当不起“文化输出”的重任。
必须承认的是，作为视频内容行业的从业者，李子柒已经用粉丝和流量证明了自己的成功，但究竟是不是要抢占“文化输出”的名头，目前来看，更多是公众讨论中赋予的意涵。
每一个新媒体产品都有自身的定位，喜欢与否都是双向选择，只要符合法律要求和道德规范，他人无需苛责。
实际上，在互联网连接世界、中国影视作品不断走出去的今天，某个博主的视频走红也存在着必然因素。
网友的争议，表面上是探讨文化输出，但更多折射出对待传统文化传承发展的不同态度：在今天这样一个商业社会，“采菊东篱下，悠然见南山”的田园牧歌是否还有时代价值？面对互联网包装和营销手段，传统文化如何自洽地走向未来、走向世界？沿着这个视角望去，那么在李子柒镜头下，传统的笔墨纸砚、蜀绣，古法制作的苏式鲜肉月饼、桂花酒，这些流传于上千年历史之中的技艺，浸润着岁月的打磨和一代代人的匠心。

A maverick refuses to follow the customs or rules of a group to which he or she belongs. In the US, a maverick is often admired for his or her free spirit, although others who belong to the maverick’s group may not like the maverick’s independent ways.But where did the word “maverick” come from?Early in the 1800s, a man named Samuel Augustus Maverick settled down in Texas, which was a place of wide-open land, rich soil, cattle ranches(牛场) and cowboys. As the years passed, Mr. Maverick increased his property(财产) in Texas. Before long, he owned huge pieces of land that were good for raising cattle. But he had no cattle. He wasn’t a rancher.One day, a man came to Samuel Maverick to pay him an old debt. But the man didn’t have enough money. So he offered Mr. Maverick 400 head of cattle. Mr. Maverick accepted them, but he didn’t really want them. He simply put the cattle on his land to eat and care for themselves.It was not long before the cows reproduced(繁殖). The calves grew and had more calves. Soon, hundreds of cows and calves moved freely across Samuel Maverick’s land. They also moved across the land of nearby ranch owners.It was a tradition among ranchers in the West to put a mark of ownership on newborn calves. They burned the name of their ranch into the animal’s skin with a hot iron. The iron made a clear mark called a “brand”. Brands allowed ranchers to easily see who owned which cattle.Samuel Maverick refused to brand his calves. “Why should I?” he asked. If all the other cattle owners brandedtheirs, then those without a brand belonged to him.And this is how the word “maverick” entered the American language. It meant a calf without a brand. As time passed, the word “maverick” took on a wider meaning. It came to mean a person who was too independent to follow even his or her own group.4. Why did the man give Samuel Maverick 400 head of cattle?A. To get some money.B. To return what he owed him.C. To buy some of his land.D. To ask him to raise them.5. How could the ranchers easily know who the cattle belonged to?A. Through the brand on the cattle.B. Through the name of the cattle.C. Through the appearance of the cattle.D. Through the land on which the cattle stayed.6. What can we learn about Samuel Augustus Maverick from the text?A. He was born in Texas.B. He took good care of all his cattle.C. He didn’t really want to accept the cattle.D. He followed the tradition of ranchers in the West.7. What is the text mainly about?A. How to become an independent thinker.B. “Maverick” means a calf without a brand.C. The life story of Samuel Augustus Maverick.D. How the word “maverick” got into American English.CWhen girls play with cars, they're serious. It was at primary school that Gu Huijing first became interested in cars after watching some car-themed movies. Born in2004 inShenzhen, Guangdong province, Gu decided to major in automobiles (汽车) when she was in junior high.She's driven by interest, but she is also a realist. “I think the future of the automobile industry is bright because we cannot live without food, clothes, houses and cars,” she said.In April, she won first prize at a competition for vehicle maintenance (车辆维修) in Dongguan city, which drew 33 teams from different cities across the province.“I thought it couldn't be that hard to repair cars when I started to take courses, but I was totally wrong,” Gu said. When she started learning in 2019, she was frequently confused by various problems. “And competition within our school is intense, so I had to work extra hard,” she said.Her teacher once tried to persuade her to give up as she was a sophomore (大二学生), and wasn't as knowledgeable as the seniors, and no women had ever been selected for the competition before. “But I insistedthat I would carry on,” she said. Finally, her training and hard work won her the only place to stand for her school at the competition.A woman winning first prize in a vehicle maintenance competition became a hot topic on-line, causing heated discussions over gender (性别) and career choices. “Women should not be influenced by old-fashioned thinking, and should do whatever it takes to discover their interests and strengths. There are more possibilities out there,” one netizen wrote.Gu said, “Many people think vehicle maintenance is a job for men. That's wrong. I don't think gender has anything to do with choice of jobs.” “I have a goal and I will work harder to make it happen,” she added. “I will be responsible for my choices.”8.

文化相对主义是看待不同民族文化的主要视角之一。
文化相对主义是针对文化普遍主义提出的，后者认为欧洲文化是超越民族和国家的世界文化标准，其他文化只有进化为欧洲文化才会走出野蛮、步入文明。
与之相较，文化相对主义放弃从整体的角度对文化进行把握，认为每个民族文化都具有其合理性，文化的价值不是外在的而是内在的；文化相对主义反对文化形态间进行优劣比较，强调文化间不可比较的独特性和文化价值的多样性，提倡尊重文化差异。
文化相对主义为人们客观地认识多元的民族差异及历史演进提供了理论基础。
在文化全球化的今天，为后发达地区增强文化自信、保持文化独立和对抗“文化殖民主义”提供了理论支撑和文化逻辑。
然而，就文化本身来看，文化相对主义也有其局限。
在文化的产生和延续上，文化相对主义认为文化因其特定的空间性和时间性而有特殊的个性，文化的产生和发展是人完全适应客观环境的结果。
一方面，这种观念忽略了文化创造主体的能动性。
人的自我实现是文化产生的动力，也是文化的归宿。
人在对自然的理性超越中，采取具有目的性和创造性的实践活动，在改变环境的同时塑造了人自身，从而产生了文化。
作为文化主体的人不断冲破各种障碍、超越自我，逐渐实现人的自身价值。
另一方面，文化相对主义忽视了文化的创造性和自我超越性品格。
作为人实践活动的产物，文化表现为一定的历史性，并在一定程度上决定了人当下的行为方式。
同时，作为有目的性的文化创造，文化还具有引领未来的超越性。
我们不能因为文化具有时间性和空间性的特征，就故步自封、放弃文化创造的能动性和超越性，否则文化相对主义就会成为一个民族进步发展的障碍。
从文化的评价来看，文化相对主义强调每一种文化都是一种独特的价值存在，文化价值评判的标准在于其自身，而且这种价值标准只对一种民族有效，对其他民族就失去了意义。
2019-2020学年昆明市实验中学高三语文一模试卷及答案
2019-2020学年昆明市实验中学高三语文一模试卷及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下列小题。
疫，这一中国古代史书中的常见名称，是指由各种致病性微生物或病原体引起的传染性疾病，自有人类以来，疫病就伴随而生。
中华民族始终在同疫病进行着顽强的斗争，并在斗争中把疫病的防治和自然环境、社会人生联系在一起，逐步形成了自己独有的天道、人道、医道合一的思想。
天道、人道、医道合为一体，使得中国古代的医学理论不仅仅是疫病医学，还是具有丰富人文内涵，包括哲学、艺术、道德、宗教等在内的一种综合性的人文生命学，一种被古人称之为“生生之具”的关于生命智慧和生命艺术的学问，是中华优秀传统文化的一部分。
中华医道以天人合一思想为核心，形成了天人感应、顺应自然、整体关联、阴阳平衡、调和致中、五行生克的阴阳五行学说和脏肺经络学说相结合的整体医道观，构建起一整套“治未病”的养生之道和望闻问切诊断，针灸、按摩推拿、经方等“治已病”的理论和方法。
在这种整体论的指导下，中国医学形成了“阴阳四时者，万物之终始也，死生之本也，逆之则灾害生，从之则苛疾不起”的疫病生成观；形成了“医之上者，理于未然，患居虑后，防处事先”的疫病预防观；形成了防微杜渐，治病求本，适时为度，辨证施治、扶正祛邪的疫病治疗观；形成了“病从心起”，故“治心”“修养”的修心养性观和饮食法地道，居处法天道，制喜制怒的养生观；形成了驱邪避毒、斋戒沐浴、打扫庭院、掸尘扫房，强身健体的卫生健康观；形成了“悬壶济世”“大医精诚、仁心仁术”“医者仁心，医德为先”“妙手回春，杏林春暖”的医德观。
医道与中国传统文化中的天人合一思想“道合理同”，密切关联。
医道作为天道与人道在自然与人之间的体现者和践行者，从知行合一的实践层面把天道与人道中许多抽象的理念体现出来。
因此，要理解天道和人道合一的思想，就应当对医道有所了解，否则对天人合一的理解只能够停留在一个抽象的哲学理论层面。

公元前11世纪，武王伐纣，建立了周王朝。
两年后，武王去世，周公摄政。
周公分析了殷代列王的为政之道，得出了殷亡于“失德”的结论。
鉴于此，他提出了施行“德政”的政治纲领。
而要保证“德政”的实施，首先是要建立一套全新的政治制度，其次是要为统治者制订一套系统的行为规范。
二者可以统称为“礼”。
这是一场比武王克商意义还要重大的革命。
风俗的转换要比政权的转换困难得多，也复杂得多。
如何移风易俗？儒家认为，应该“因俗制礼”，即尽可能利用既有风俗的形式和内在的合理部分，再加整理、提高，注入新的精神，如此方可使人民喜闻乐见，被其所化。
因此，《周礼》中的大司徒官政之法有几条很重要的原则：一是“辨五地之物生”，全国的土地可以大体分为山林、川泽、丘陵、坟衍、原隰五类，其物产及居民的体质特征也各不相同，这是为政者首先要分辨的；二是“因此五物者民之常，而施十有二教焉”，辩明上述五类地区，目的在于摸清各自的风俗，然后才可以藉此而施以“十二教”礼仪；三是“以本俗六安万民”，要沿袭当地原有的宫室、族葬、衣服等六类旧俗，使人民安于其居。
