2021届东莞市南开实验学校高三英语期中考试试题及参考答案第一部分阅读（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ANo one knows when the first printing press was invented or who invented it. but the oldest known printed text originated in China during the first millennium (千年) AD.The Diamond Sutra (《金刚经》), a Buddhist book from Dunhuang, China during the Tang Dynasty, is said to be the oldest known printed book.The Diamond Sutrawas created with a method known as block printing (雕版印刷), which used boards of hand-carved wood blocks in reverse.It was said that the moveable type was developed by Bi Sheng. He was fromYingshan,Hubei,China, living from 970 to 1051 AD. His method replaced panels of printing blocks with moveable individual Chinese characters that could be reused. The first moveable Chinese Characters were carved into clay and baked into hard blocks that were then arranged onto an iron frame that was pressed against an iron plate.The earliest mention of Bi Sheng’s printing press is in the bookDream Pool Essays, written in 1086 by Shen Kuo, who noted that his nephews came into possession of Bi Sheng’s typefaces (字体) after his death. Shen Kuo explained that Bi Sheng did not use wood because the texture is inconsistent (不一致的) and absorbs wetness too easily.By the time of the Southern Song Dynasty, which ruled from 1127 to 1279 AD, books had become popular in society and helped create a scholarly class of citizens who had the capabilities to become civil servants. Large printed book collections also became a status symbol for the wealthy class.1. When was Bi Sheng’s printing press first introduced in history?A. After Bi Sheng died and his nephews owned his typefaces.B. When books became popular in the Southern Song Dynasty.C. After the block printing was replaced by the moveable type printing.D. WhenThe Diamond Sutrawas printed into a book.2. What can we infer from the passage?A. Shen Kuo made great contributions to printing.B. The moveable type printing was invented earlier than block printing.C. Printed books were hard to get in the Song Dynasty.D. By the Southern Song Dynasty, books had helped people get to higher social positions.3. Why does the author write this passage?A. To show that Buddhism was popular in the Tang Dynasty.B. To introduce the early history of printing.C. To memorize Bi Sheng, developing the moveable type printing.D. To indicate the advantages of moveable type printing.BA teenager in Georgia will no longer have to walk 7 miles to work after school thanks to one woman’s act of kindness.Jayden Sutton, a high school senior, went on foot each day from school to his job at a restaurant and then back home. Sutton was determined to work and make enough money to eventually buy his own vehicle.Sutton said he’d leave school at 3:30 pm, then walk miles to his job at the restaurant. After his work, which usually lasted six to eight hours, he walked home, sometimes not arriving back until almost midnight.That all changed when Myers saw him walking down the road in the rain in December. “The young man was insistently in a rush walking to work, saying ‘I can’t be late,’” Myers said. “He begged me to give him a ride. I told him I could take him as far as I was going. I began to create small talk along the way. It wasrevealedto me that his name was Jayden, 12th grader, worked 40 hours a week, walked 5 miles to work immediately after school, got off at 10:30 pm at night and walked back home another 5 miles if co-workers didn’t offer a ride.”After dropping Sutton off, Myers said his heart and determination filled her with tears. “He was smiling in good spirits and that’s a child worth blessing,” she told Fox News. So, Myers shared Sutton’s story on the GoFundMe page, which raised more than $ 9, 000 from 186 donors.She surprised Sutton with a new car after she managed to convince the general manager to drop the price of the vehicle to meet the budget.4. Why did Sutton work so hard in his spare time?A. To gain working experience.B. To pay for his education.C. To own a car.D. To support his family.5. What difficulty did Sutton have in his work at the restaurant?A. He worked longer than other workers.B. His work was too tiring.C. His job was much less paid.D. He had to walk to work.6. What does the underlined word “revealed” in paragraph 4 mean?A. Known.B. Attached.C. Believed.D. Limited.7. What do we know about the money donated online?A. It could buy more than a new car.B. It was not enough to buy a new car.C. It was given to Myers to buy herself a new car.D It mainly came from a car sales manager.CSometimes people make history. George Washington became the first president of theUnited Statesand made history. Sometimes wars make history. The two World Wars are examples. Sometimes nature even becomes part of history. Shaking earthquakes are recorded in history books.Sixteen years ago, nature caused just such a history-making event. In September 2005, Hurricane Katrina came ashore inNew Orleans,Louisiana. The deadly storm floodedNew Orleans. Before Katrina, no other big American city had ever flooded in the history of the country. This natural disaster caused great harm and death.New Orleansis located below sea level. This location places it at great risk. Levees were built to protectNew Orleansfrom the ocean. (A levee is like a wall between the city and the ocean.) When Hurricane Katrina came ashore, water moved over the levees into the city. Flooding made it necessary for everyone to leave the city. Before Katrina, Creole food (a special kind of cooking only inLouisiana) filled the air with delicious smells. The sound of jazz music traveled through the streets. Now the city has to return to its former glory.Before Katrina, ernment had never made everyone leave a city. People inNew Orleanshad to find shelter quickly. Some had to stay at theSuperdomeSportsCenter. Some rode on buses to other towns. Thousands drove their cars to get away from the storm. The roads and shelters filled up fast.The lesson learned from Katrina was that cities must be better prepared for big storms and other terrible disasters caused by nature. Being prepared might have kept more people safe. Hurricane Katrina is one of the history-making events that will be remembered forever. Today, history is still being made that will shape the future.8. What does the author tell us aboutNew Orleans?A. It was built above sea level.B. It had few jazz musicians after Katrina.C. It was the firstU.S.city that had been flooded.D. It created a wholly new way to cook after Katrina.9. What can we say about the levees?A. They were almost useless for fighting Katrina.B. They helped people leaveNew Orleansquickly.C. They made NewOrleansa special American city.D. They should be built to match the size ofNew Orleans.10. What might the author advise city governments to do?A. Put up more shelters in the city.B. Build more levees around the city.C. Teach people how to avoid floods.D. Try to get ready for natural disasters.11. What is the best title for the text?A. Storms are dangerousB. Katrina makes historyC. Floods shapeLouisianaD. History must be rememberedDAs I work in theLarkwhistle Garden in Dyer's Bay, Ontario, I take my time and the garden is teaching me about working with the earth. I recognize that there will be both successes and failures and there are many variables(变量)that affect them both.The quality of the seeds planted has a bearing on how the plants will grow. The weather can be too hot, too cold, or exactly right, and usually varies between all three. Weeds seem to grow in the garden and need to be taken care of, pulled, and removed to ensure they do not eat into the fruits, vegetables, and flowers we have so lovingly planted.I take time to stand back and rest, and to observe the plants and how they are growing. Each plant is unique and develops in the way that is best for them. Some have large broad leaves to shadow their fruit from the severe rays of the sun, while other plants are more open, their fruit needing the light to grow and ripen.Getting my hands dirty, feeling the sweat on my forehead, and the strength and flexibility of my body as I dig, bend and work under the warm summer sun, reminds me I am alive in ways I would not have remembered sitting on the couch.It is attractive to move things around, to transplant, and to disturb the natural order of how plants grow. The garden teaches me that it is important to know when to disturb things and when to let them be. The garden's life cycle follows a pattern that is repeated according to laws of nature, birth, growth, and then dies and it teaches us to accept this fact.12. How many variables may affect the growth of plants in the garden?A. Two.B. Three.C. Four.D. Five.13. What can we learn about the author?A. He feels exhausted while gardening.B. He enjoys life from working practice.C. He takes pleasure in harvesting fruits.D. He dreams away his time in the garden.14. How is the garden tended by the author?A. Its rank grass is got rid of.B. Its plants are left to grow freely.C. Its temperature is controlled properly.D. Its plants with large broad leaves are cut off.15. What fact does the author learn from gardening?A. Life takes its course.B. Hard work benefits health.C. Time is short and precious.D. Gardening brings good harvest.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。

2021届东莞市南开实验学校高三英语期中试题及答案解析
2021届东莞市南开实验学校高三英语期中试题及答案解析第一部分阅读（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AWhile Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past？Or was she slowing down？In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of online education. This technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't searched the Internet to get the right answers.Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses". Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.1. Why was Jennifer watched in an online exam?A. To correct her typing mistakes.B. To find her secrets in the room.C. To keep her from dishonest deeds.D. To prevent her from slowing down.2. What does the underlined expression "cutting edge" in Paragraph 3 probably mean?A. sharpening toolB. advanced techniqueC. effective ruleD. dividing line3. How can some programs find out possiblecheaters?A. By scanning the Internet test questions.B. By checking the question answering speed.C. By producing a large number of questions.D. By giving difficult test questions.BBrain cells work to actively forget memories during a specific period of sleep. When we sleep our brains clear out the memories we’ve made while we’re awake, deciding what to keep and what to get rid of. Forgetting is an active process, explained the authors of the study published in the journal Science. But less is known about this process during the different periods of sleep.They found that during the rapid eye movement (REM ) sleep period — or active sleep when we are thought to dream — special nerve cells appear to actively contribute to forgetting. What are known as melanin-concentrating hormone-producing (MCH) neurons (神经元) sit in the hypothalamus (下丘脑): a part of the brain which helps with a range of functions such as sleep, appetite and emotions. Past research has suggested these cells help to control REM sleep patterns: activating the MCH neurons increasing time spentin this period, while preventingthemreducing changes into this period.The scientists looked at MCH cells in mice, and found 52.8 percent were active during REM sleep, compared with 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.4. What can we infer from paragraph 1?A. Forgetting is a passive process.B. The forgetting process is known to us.C. Some memories are forgotten while we are awake.D. Certain memories are removed while we are asleep.5. What does the underlined word “them” in paragraph 2 refer to?A. REM sleep patterns.B. Past researches.C. MCH neurons.D. A range of functions.6. Why did Kilduff’s team conduct the research?A. To publish the study in the journal Science.B. To know more about Alzheimer’s disease.C. To contribute to human’s forgetting.D. To explore our everyday lives.7. What can we know about MCH?A. MCH cells takes control of REM sleep patterns .B. MCH neurons may disturb memory consolidation.C. MCH neurons have nothing to do with forgetting.D. MCH cells help mice performing better on learning.CScientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color1 from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, theyhaltthe interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 millionevery year.To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.8. What does the underlined word "halt" in the first paragraph mean?A. End.B. Develop.C. Strengthen.D. Weaken.9. What do Muller and her team do to save corals?A. Restore the damaged reefs.B. Grow corals by hand underwater.C. Create more protected areas.D. Move corals to unpolluted areas.10. What do Gunning's words suggest?A. Many corals have been genetically improved.B. Cooling down the waters is key to rescuing corals.C. Reasons for corals surviving heat waves are shocking.D. The highest temperature corals can survive is unclear.11. Which can be a suitable title for the text?A. Relationship between corals and algaeB. Efforts made to save coralsC. Impact of climate warming on coralsD. Survival crisis faced by coral reefsDJapan has announced emergency Covid measures in Tokyo and three other areas in order to control rising infections (传染病), just three months before the country is set to host the Olympics. The government said the state of emergency — set to last for about two weeks— would be “short and powerful”. Under the measures, bars will be required to close and big sporting events will be held without audience. The government has insisted that the Olympics will go ahead in July.Prime minister Yoshihide Suga announced the measures on Friday, saying they would begin on Sunday and remain in place until 11 May. In addition to to Tokyo, Osaka, Kyoto and Hyogo will be affected. It has marked the third state of emergency in japan since the pandemic began. “I sincerely apologize for causing trouble for many people again,” he said. “It is feared that infection in major cities will spread across the whole country if we take no measures.”Under the rules, major facilities like department stores will close, as well as restaurants, bars, and KTV rooms serving alcohol. Restaurants that do not serve alcohol are being told to close early, and companies are being asked to make arrangements for people to work remotely. Schools will remain open. Besides, the emergency measurescoincide withthe country’s “Golden Week” holiday, which runs from late April to the first week of May and is the busiest travel period of the year. Tokyo governor Yuriko Koike urged residents to start taking precautions immediately. In an effort to discourage people from going out at night. She said neon signs (霓虹灯) would be turned off.The coronavirus toll in Japan has been much lower than that in many other countries, with about 558,000 cases and fewer than 10,000 deaths, according to figures collected by Johns Hopkins University. But there are concerns over the latest rise in infections, with reports of hospital bed shortages in some areas.Tokyo 2020 president Seiko Hashimoto said at a news conference on Friday that organizers were not considering canceling the event. “I hope the coronavirus situation improves with the prevention measures the government, Tokyo, and other regional governments have put into place,” she said. “We, as Tokyo 2020, continue to wish for the swift return to normal and will continue to work closely to make sure a safe and secure Olympics can happen.”12. According to the passage, what does Japanese government advise people to do?A. To watch a live game.B. To work at home.C. To hang out in the evening.D. To study at home.13. What is the aim of bringing in emergency Covid measures?A. To relieve people's fear of the the pandemic.B. To settle the problem of hospital bed shortages.C. To test government’s management of emergency.D. To ensure the smooth running of the upcoming Olympics.14. Which words can best describe the government’s action?A. generous and brilliant.B. costly but useless.C. positive and considerate.D. accidental but efficient.15. What does the underlined phrase “coincide with” in Paragraph 3 mean?A. meet withB. deal withC. make upD. set up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。

2021年东莞市南开实验学校高三英语期中考试试题及参考答案第一部分阅读（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AOver the years, I’ve been guilty of hastily shutting the front door to many strangers when they came knocking with the intention of selling things. But earlier this year, around Easter time, a dear friend of mine had an experience that changed my mind and perception towards these “intruders”.Linda, who recently moved to a new neighbour hood, had been housebound all week suffering from a severe case of flu when, early one morning, there was the terrible knock on her front door. Peering out the window, she saw two young ladies demurely (端庄地) holding leaflets and a TV set model. She knew of a large TV set establishment nearby and assumed a message was about to be gently delivered. “This is the last thing I need today,” she muttered to herself and hesitantly opened the door.Coughing, she poked her head out and impatiently informed them she wasn’t the slightest bit interested in any TV whatsoever. Furthermore, she added, she was feeling quite unwell and abruptly shut the door. The ladies politely turned and left in silence.A few hours later, another knock. Linda glanced out the window and to her surprise, there were the same two ladies, back again. Really annoyed this time, she opened the door ready togive them a piece of her mind. Before she could speak, with concerned looks on their faces, these women handed Linda what looked to be a dish, saying, “We’re so sorry we disturbed you earlier. We thought you may like this homemade chicken soup. Hopefully it might make you feel a little better.”Linda was taken aback by this lovely gesture. Being new to the area, she didn’t know many neighbours or people who could assist her with shopping or errands (跑腿) so the gesture was all the more appreciated. She could only smile sheepishly and sincerely thanked them. With that, the ladies left.After she related this story to me, I thought about how touching this deed really was. Especially in today’s world where sadly, kindness and thoughtfulness seem so rare. I also realized that thinking about others and showing kindness is the real essence of love.1. What does the expression “give them a piece of her mind”in Paragraph 4 mean?A. Scold them severely.B. Drive them away.C. Refuse them directly.D. Speak out her idea.2. What can be learned about Linda from the passage?A. Linda always hastily shut the front door to many people.B. Linda was not a little interested in any TV whatsoever.C. Linda was very grateful to the ladies for their chicken soup.D. Linda would buy their TV set in reward for the ladies’ chicken soup.3. What’s the best title for the passage?A. A Chicken SoupB. Soup for the soulC. The Real Essence of LoveD. A Friend’s experienceBOnce small farmers in Masii, a remote village in Kenya, have picked their crops, all they can do is wait until a buyer trucks through. The system works fairly well for beans and corn, but mangoes-the area’s other main crop-spoil (腐烂) more quickly. If the trader is late, they rot.However, a simple coating could change that. A company, SmartTech, has created a product that doubles the shelf life of fresh produce, enabling farmers to access far-off, larger markets. More time forfresh produce on grocers’ shelves also means less food waste-a $2.6 trillion problem, according to the United Nations’ Food and Agriculture Organization (FAO).James Rogers, CEO of SmartTech, wanted to solve the problem for food much in the same way that oxide barriers preventing rust (锈) have achieved for steel. Fortunately, researchers have found when plants made the jump from water to land, they developed cutin(蜡质), a barrier which is made of fatty acids that link together to form a seal around the plant, helping keep water in.The cutin was such a grand strategy that today you’ll still find it across the plant kingdom. SmartTech discovered through researches that an orange can last longer than a strawberry not so much because of the thickness of its skin, but because of the difference in the arrangement of those cutin molecules (分子)on the surface. After extensive trials, Rogers and his team developed a natural and tasteless protective coating from plant material-stems, leaves and skins. The product extends the sweet spot between ripening and rot. And best of all, the treated produce doesn’t require refrigeration.“SmartTech has huge potential to turn poor farmers in Africa into commercial farmers,” says Rogers. “That means more money in pockets, and more food in stomachs.” But whether the company can cost-effectively reach small farmers in far-off areas still remains a challenge.4. The author mentions the small farmers in Kenya to ________.A. stress their need for preserving produceB. show their challenge in harvesting cropsC. express their wish to reach larger marketsD. evaluate their loss caused by slow transport5. What can we learn about SmartTech’s product?A. It is financially supported by FAO.B. It is intended to replace refrigeration.C. It is designed to thicken produce’s skin.D. It is based on plants’own defence system.6. What will James Rogers probably focus on next?A. How to expand farms.B. How to earn more money.C. How to produce more tasty food.D. How to profit farmers in remote area.7. The main purpose of the passage is to ________.A. promote a productB. present a technologyC. advertise SmartTechD. introduce James RogersCA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed theequivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”8. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.9. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA10. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible11. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effectDWhat acts of kindness will make us the happiest, and who tends to benefit the most? A newly-published review of decades of kindness research provides some answers.In this paper, researchers analyzed the results from 126 research articles looking at almost 200, 000 participants from around the world. The studies they chose measured well-being in various ways, including both mental and physical health. Some were experiments, where people did a kindness practice to observe its effects, while others just surveyed people about how kind and happy they were.As expected, people who were kind tended to have higher well-being. Lead researcher Bryant Hui wasastoundedthat the relationship wasn't stronger than it was, but he was still encouraged by the results.One thing Hui and his colleagues found was that people who performed random, informal acts of kindness, like bringing a meal to a sad friend, tended to be happier than people who performed more formal acts of kindness, like volunteering in a soup kitchen.The researchers also found that people who were kind tended to be higher in "eudaimonic happiness"(a sense of meaning and purpose in life) more than "hedonic happiness"(a sense of pleasure and comfort). Perhaps this makes sense, given that being kind takes effort, which reduces comfort but could make people feel better about themselves and their abilities, which would provide a sense of meaning.Being kind came with greater eudaimonic happiness for women than for men, too. According to Hui, this could be because, in many cultures, women are expected to be kinder than men; so, they may have more to gain from it. And younger participants experienced more happiness when they were kind than older participants, perhaps for developmental reasons, he says.Hui isn't sure why acting kind might have these different effects on different groups, but he points to theories put forth by researcher Elizabeth Midlarsky: Being kind may make us feel better about ourselves as a person or about the meaning of our lives, help us forget our own troubles and stresses, or help us be more socially-connected with others.12. What does the data in the second paragraph intend to show?A. The recent paper is worthy of being read.B. The recent paper gives convincing results.C. Kindness is always a hot topic of research.D. Kindness is closely linked to one's well-being.13. What does the underlined word "astounded" in paragraph 3 mean?A. Afraid.B. Certain.C. Excited.D. Surprised.14. Which of the following acts of kindness can make one feel happier according to paragraph 4?A. Volunteering in a hospital.B. Cleaning a community.C. Returning a lost item to its owner.D. Collecting donations for the poor.15. What do the researchers find from the paper?A. Being kind has different effects on different groups.B. Eudaimonic happiness makes people feel comfort.C. The younger experienced more happiness than the older.D. Female participants are kinder than male ones.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。

At 8 p.m.BYou may have heard of the famous saying, “East or West, home is the best.” What does the word “home” mean to you? How do you say the word in French, in Chinese, in your language? Although people usually know what the word means, it sometimes has no exact translation. It’s not surprising, because the idea of home is different from country to country, and from person to person. A home is more than a roof and four walls. It’s the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there’s a f ire in the living room or kitche and all the chairs face it. In the south, where the sun shines a lot and it’s more inportant to keep the heat out, there are small windows and cool stone floors.We asked some people about their homes.How often do people move house in your country?“In my countr y many people don’t stay in one place for a very long lime. They often move every ten years or so.”---Chery, Boston, USA.What are features(特征) of homes in your country?“In Britain, even in town, there’s always a garden. We have separate bedrooms and living room. But we don’t often have balconies(阳台). The weather isn’t warm enough!”---Pat. Exeter, England( )61.
