It is run by Kevin Cillen, a 28-year-old Belgian who is passionate about the land. With his parents and siblings, they have combined Western farming techniques with local countryside practices to cultivate an “ecological oasis”.The family’s pursuit of their farming dream in China began in 2000, when Kevin’s mother Hetty Cillen visited China as a volunteer for the first time. The enchanting landscapes and rich cultural heritage of Guizhou fascinated her, causing her to make this foreign country her home. Soon after, his father Patrick Jan Cillen joined her. In 2017, the family rented a plot amid the forest to establish an ecological farm where they laid the foundation, leveling the land, sowing pastures and rearing lambs and chicks.The locals have openly embraced the foreigners, inviting them to festivities and celebrating traditional Chinese holidays together. In 2018, Yang Chengkai, a 34-year-old villager, befriended the family, often assisting them on the farm. “The community has embraced this family. Even the vendors at the local market contribute by giving them vegetable scraps for free to feed their livestock.” Yang says.The family farm, hidden within the dense forest, is proof of Guizhou’s ecological progress. The farm practices diversified grass cultivation for high-quality animal feed, uses solar panels for clean energy and employs rainwater harvesting systems for a stable water supply.Living in China, the 28-year-old Belgian has witnessed the country’s remarkable changes.He has also seized the opportunities of the Internet and new media to increase the farm’s visibility. Partnering with Qiu Ye, a social media influencer, he has set up accounts like “Kevin’s family in Guizhou” on various platforms. By sharing their daily lives on the farm and the natural beauty of rural China, their content has quickly earned over 700,000 subscribers.4.What made Hetty Cillen decide to settle in Guizhou?A.The natural beauty.B.V olunteer work.C.A research project.D.Career prospects.5.How does the family farm contribute to ecological progress in Guizhou?A.By creating jobs for the locals.B.By introducing Western equipment.C.By practising sustainable way of farming.D.By facilitating eco-tourism and green living. 6.How has Kevin promoted the farm?A.He has created a website.B.He has set up social media accounts.C.He has it advertised by local villagers.D.He has organized events for subscribers. 7.What might be the best title for the text?A.Belgians Harvest a Good Farm Life in GuizhouB.Belgians Get Enchanted by the Beauty of GuizhouC.Belgians Become a Social Media Influencer in ChinaD.Belgians Live in a Local Chinese CommunityIn the Roman times and throughout the Middle Ages, salt was a valuable commodity (商品), and also served as “white gold”. Soldiers in the Roman army were sometimes paid with salt instead of money. Their monthly allowance was called “salarium” (“sal” being the Latin word for salt). This Latin root can be recognized in the French word “salaire” and it eventually made it into English as the word “salary”.Language is something we take for granted. However, as the example with the word “salary” shows, languages are not static. Like biological species, languages change over time, and sometimes develop to give rise to several descendant (后代) languages. For example, French, Italian, and Spanish are among the languages that have evolved from Latin. And like species, languages can go extinct, too.Given all these similarities, linguists (语言学家) who study the evolution of languagesoften use tools that are similar to those used by evolutionary biologists. One such tool is the reconstruction of a species tree. Such a tree shows the evolutionary history and relationships within a given group of biological species.Using a reconstructed species tree, evolutionary biologists can often infer specific characteristics of ancestral species. Or they can match up common ancestors in the tree with actual fossils that have been found by paleontologists (古生物学家). This allows them to put real dates at various branching points in the tree. Thus, species tree reconstruction is an essential tool in studying biological evolution.A similar technique can be used to study language evolution because languages also evolve and consist of words that can be easily compared. Indeed, linguists have reconstructed entire language trees. And as with species trees, characteristics of ancient ancestral languages can be derived (衍生) from them.Of course, there also are some differences between species evolution and language evolution, each requiring unique additional methods to study them in detail. But, overall, it is fascinating to see how the basic ideas and research tools of language evolution are similar to those of biological evolution.8.Why does the author mention the word “salary” in paragraph 1?A.To illustrate the evolution of language.B.To present the effect of Latin on languages.C.To stress the value of salt in ancient times.D.To show developments in linguistic theory.9.What can we infer from paragraph 2?A.Cultural diversity and biodiversity are linked.B.Species and languages have a lot in common.C.Human-caused mass extinction is accelerating.D.Languages influence and learn from each other.10.What can we know about the reconstructed species tree?A.It is currently in the design stage.B.It facilitates the research of linguists.C.It can be used in a variety of ways.D.It is the first choice for biologists. 11.What can be the best title for the text?A.The Language System Evolved Over TimeB.The Twin Extinctions of Species and LanguagesC.Salt Played a Crucial Role in Early Human HistoryD.From Salt to Salary: Linguists Take a Page from BiologyHere’s a quick quiz. Person A does a favor for you. Person B asks you to do a favor for him. Who do you tend to like more? Surprisingly, the answer is Person B.This quirk (怪癖) of human nature is known as the Ben Franklin Effect.Benjamin Franklin came across the phenomenon in 1736 when serving as a clerk to the Pennsylvania Assembly. A powerful member didn’t care for Franklin and threatened to make life miserable for him. What to do? Instead of winning him over with sweet talk, Franklin asked if he could borrow a rare and valuable book the man owned. This request altered the man’s attitude and paved the way for their friendship. Franklin’s takeaway: “He that has once done you a kindness will be ready to do you another, than he whom you yourself have obliged.”Several studies have confirmed this. But how can we explain the Ben Franklin Effect? Some psychologists refer to cognitive dissonance (失调). It’s difficult to hold two contradictory thoughts at the same time. It makes us uncomfortable. We resolve this tension by changing our mind. “I don’t like Joe, but I am doing him a favor,” we might think. “So maybe I do like him.”While cognitive dissonance explains a lot, it alone doesn’t explain the Ben Franklin Effect. One 2015 study found that it was, rather, the affiliative (亲和的) motive that the requests convey. That is, we humans want to maintain good relations with other humans, and one way to achieve this is by doing favors for others. This explains a lot about altruistic behavior. We like being useful and, by extension, we like those who give us the opportunity to do so. It’s in our genes.Yet there is much we still don’t know about the Ben Franklin Effect. Does it apply equally across cultures? Is there a point beyond which asking a favor makes you less, not more likable? Asking to borrow a book is one thing; asking to borrow a car is another.12.Why does the author mention Benjamin Franklin’s experience?A.To illustrate a dilemma in making choices.B.To suggest a way of striking upfriendships.C.To stress the importance of strategic requests.D.To introduce the origin of the BenFranklin Effect.13.What is a reason for people’s tendency to like those asking for favors?A.Reducing the tension caused by social contact.B.Increasing the chance of getting help in return.C.Avoiding the discomfort from conflicting thoughts.D.Establishing a cooperative community of shared trust.14.What does the underlined word “altruistic” probably mean in paragraph 4?A.Selfless.B.Impolite.C.Aggressive.D.Responsible. 15.What does the author think of the Ben Franklin Effect?A.It makes little sense.B.It applies to most cultures.C.It has situational limitations.D.It has great practical significance.In the dynamic world of fitness, where treadmills (跑步机) hum and weights clink, an emerging concern for sustainability is reshaping the gym experience. 16 ? In this guide, we’ll navigate through key aspects of eco- conscious fitness to help you figure out if your gym is on the sustainable track.●Energy-efficient equipmentA sustainable gym starts with the tools that push your workout.

Are the machines equipped with energy-efficient features? Do they employ the energy generated during workouts to contribute back to the gym’s power needs?● 18The infrastructure (基础设施) of a gym plays a crucial role in its sustainability journey. The use of eco-friendly materials, energy-efficient lighting and strategic design for natural air circulation are key elements of a green fitness space.Explore the infrastructure of your gym. Does the overall design facilitate natural air circulation and use sustainable construction practices?●Waste managementAs you are sweating it out at the gym, what happens to the waste generated? Sustainable fitness spaces prioritise comprehensive waste management systems. 19 .Direct your attention to how your gym manages waste. Are there visible recycling programs for plastics, paper and other common gym materials? Does the gym use eco-friendly cleaning products, demonstrating a commitment to minimising its environmental impact?● Renewable energy integration20 , but sustainable fitness facilities find innovative ways to employ renewable energy. Solar panels and other renewable energy sources are integrated into the gym’s infrastructure to offset power consumption, reducing the facility’s carbon footprint and contributing to a greener energy landscape.Investigate whether your gym is tapping into renewable energy sources. Are there solar panels or wind turbines integrated into the infrastructure?A.This involves recycling programs for common gym materialsB.Green building practicesC.Adaptable fitness facilitiesD.But how do you know if your gym is truly sustainableE.The energy demands of a busy gym can be considerableF.It’s now contributing to the joint efforts for a greener planetG.Are there signs that your workout increases carbon footprint二、完形填空My grandmother suffers from Alzheimer’s disease.

About a month ago, while in the drive through at Starbucks, I noticed a woman in a car behind me who appeared to be having a bad day.

AMy father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks.It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I’ve never been late for any job since. I also learned about being respectful and faithful to the people you work for. More importantly, I earned my pay, it never entered my mind to say I was sick just be cause I didn’t want to work.I was only six years old, but I was doing a man’s job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem(自尊心), one of the most important things a person could have.When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dream of making thousands of dollars by playing golf and being able to buy a bicycle.The more I dreamed, the more I thought. Why not ? I made my first golf club out of guava limb (番石榴树枝) and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity. I learned working in the field --- except now I was driving golf balls with club, not oxen with a broomstick.26. The writer’s first job was ___________.A. to stand down the fairway at the golf courseB. to watch over the sugar-cane plantationC. to drive the oxen that ploughed the cane fieldsD. to spot the balls as they landed so the golfers could find them27. The underlined word ―tedious‖ in Paragraph 2 most probably means ___________.A. difficultB. boringC. interestingD. unusual28. The writer learned that ________ from his first job.A. he should work for those who he liked mostB. he should work longer than what he was expectedC. he should never fail to say hello to his ownerD. he should show respect and faith to the people he worked for29. ________ gave the writer self-esteem.A. Having a family of eight peopleB. Owning his own golf courseC. Bringing money back home to help the familyD. Helping his father with the work on the plantation30. Which of the following statements is TRUE according to the passage?A. He wanted to be a successful golfer.B. He wanted to run a golf course near his house.C. He was satisfied with the job he got on a plantation.D. He wanted to make money by guiding oxen with a broomstick.BAttempts to understand the relationship between social behavior and health have their origin in history. Dubos (1969) suggested that primitive(原始的)humans were closer to the animals because they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain things and alleviating (减轻)symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes and cures of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual (礼仪) to drive harmful spirits away from a diseased body.One of the earliest attempts in the Western world to formulate principles of health care based upon rational thought and rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B.C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings attributed to him have provided a number of principles underlying modern medical practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics (道德). Among other things, it requires a physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor-patient relationship.Hippocrates also argued that medical knowledge should be derived(源自于)from an understanding of the natural sciences and the logic of cause and effect relationships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human-being is influenced by thetotality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.31. The topic of the first paragraph is summarized in ________.A. the first sentence of the paragraphB. the second sentence of the paragraphC. the third sentence of the paragraphD. the last sentence of the paragraph32. Why did primitive humans rely on magic in their beliefs about the causes and cures ofdiseases?A. Because magic was an inseparable part of their life.B. Because they had little knowledge about the functioning of the body.C. Because the diseases were caused by the evil spirits.D. Because magic must be used in going through the rituals to drive out the evil spirits.33. Considering Hippocrates’ background, we can see from the second paragraph that ________.A. he was the forefather of modern medicineB. experts are sure that the books bearing his name were not written by himC. he had a rational mind aided by supernatural instinctsD. experts do not know much about him except when and where he lived34. All of the following are included in the Hippocratic Oath EXCEPT ________.A. helping patientsB. keeping oneself from harming patientsC. keeping secret all matters to maintain a good relationship with the patientsD. obeying rules for modern medicine practice35. Which of the following best expressed the main idea of the last paragraph?A. Doctor’s concerns remain unchanged.B. Medicine comes from nature.C. Environment affects health.D. Climate determines lifestyle.CGovernments all over the world make public reports about the condition of their economies. Most countries, including the United States, have used a measure called the gross national product (国民生产总值)or GNP. It includes all goods and services produced by citizens of the country anywhere in the world.Recently the American Commerce Department has started using a new method to measure production. It is known as the gross domestic product(国内生产总值)or GDP. It counts only goods and services that have been produced within the nation’s borders. Money earned by foreign companies operating in the United States is included in the GDP, but money earned by American companies operating in other countries is not.Economic experts generally approve of the change. They say that the gross domestic product provides a truer measure of the economy. They also note that most other industrial countries use this method. Therefore it will be easier to study the economies of different countries. Some officials also hope the new system will help them make better economic policy decisions. It will provide them with a clearer understanding of economic activity in the U.S. . The new measure is less likely to be affected by sudden changes in foreign oil prices or in the value of the American dollar in other countries.Economic experts believe that the change from GNP to GDP will immediately reduce the value of American production by at least 40,000 million dollars a year. But that is really a very small change in the American economy –less than 1% . The Commerce Department reports the unofficial gross domestic product once every three months. The government also continues to report GNP as it has four times a year since 1941.36. To report the American GNP, the government should not consider goods and services produced________.A. by American companies at homeB. by American companies in ChinaC. by American companies in SingaporeD. by Japanese companies in the United States37. To report the American GDP, the Commerce Department should count money earned________.A. by both American and foreign companies in AmericaB. by American companies within its own bordersC. by foreign companies in the United StatesD. by American companies in its foreign markets38. GDP is considered better than GNP by some economists because ________.A. it is something newB. it is used by most countriesC. it is easier to calculateD. it is less likely to be affected by the foreign market39. What will happen to the value of American economy if GDP is used to replace GNP?A. It will be seriously affected.B. It will not be affected.C. It will come down a little.D. It will slightly go up.40. How often are the reports of GDP issued by the American Commerce Department?A. once every four monthsB. once every three monthsC. once every six monthsD. once a yearDDonna is 19 years old and loves animals, which is why I’m always happy to leave my dog with her when I go on holiday. Donna also helps to train hunting dogs, but recently, her boyfriend told me, she returned home from a farm in tears after being told to hit some dogs.―She wasn’t being asked to hit them because they didn’t behave well,‖ he said. ―She was told to punch these puppies with a closed fist simply to let them know who is the boss,‖ Donna refused. Good for Donna. In my view, you hit an animal for only two reasons: as a way to teach it an important lesson to protect it from danger, such as not into the road; or because you like hurting animals.Last summer, I attended a horse race. I don’t know much about horses, but I was alarmed when I saw a horse with a huge ulcer (溃疡) on its legs. ―Surely this horse won’t race?‖ I asked. I was very surprised that nobody in the crowd seemed concerned.The horse began the race, but later it fell heavily. It had broken its leg. The next thing I saw was its dead body in a bag, being driven past. No one seemed to care, except those who had bet on it. I know people care for horse racing, but do they really care for horses? I doubt it.Oh, but it’s a tradition, I hear you say. Wouldn’t the world be a boring place if we didn’t occasionally hit, shoot and chase animals? Traditions are made by man and can be unmade. It was once acceptable to kill servants when their master died, to visit the mental hospitals to laugh at the patients or to watch public execution (执行死刑).Nor should it be forgotten that in our progress to a more civilized world, animals have played an important role: they have fed us, carried us, worked for us, rescued us, died for us and sometimes just saved us from loneliness. Surely by now they deserve our kindness. At the very least, they deserve our respect.41. Donna was asked to hit the young dogs because ________.A. they misbehavedB. their owner disliked themC. people on the farm enjoy hurting themD. it was a way to train them to obey people42. What does the underlined word in paragraph 2 probably mean?A. strikeB. strokeC. scoldD. pump43. What is the author’s purpose in telling the readers the story about the horse?A. To explain the traditional horse race to readers.B. To prove that the weak horse can’t win in the race.C. To show that animals are treated unfairly by humans.D. To say that people care more for horses than horse racing.44. Which of the following is NOT true?A. People no longer watch killing criminals in public.B. The author cannot accept anyone who hits the animals.C. It was a traditional practice to kill servants for their dead master.D. The author thinks it is possible to change the traditions made by man.45. What’s the best title of the passage?A. No One Cares for Animals Nowadays.B. Let’s Protect the Endangered Animals.C. Show Animals the Respect They Deserve.D. The Stories Between Animals and People.第二节:信息匹配(共5小题,每小题2分,满分10分)阅读下列应用文及相关信息,并按要求匹配信息,在答题卡上将对应题号的相应选项字母涂黑。
