Addison Witulski's grandmother Kim Allred said Addison probably overheard a conversation between family members talking about the funds needed to get herlittle brother to treatment." I guess she overheard her grandfather and me talking about how we’re worried about how we’re going to get to Houston, for my grandson’s heart surgery,” said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.”That’s when Addis on and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.Before Allred knew it, New Mexico State Police Officers were among the many stopping by helping them reach a total of $568.The family turned to social media expressing their gratitude saying, “From the bottom of our hearts, we would like to deeply thank each & every person that stopped by!Questions 1 and 2 are based on the news report you have just heard.Q1： Who did Addison raise money for?A)Her friend Erika.B)Her little brother.C)Her grandfather.D)Her grandmother.答案：B) Her little brother.Q2： How did Addison raise money?A)By taking pictures for passers-by.B)By working part time at a hospital.C)By selling lemonade and pictures.D)By asking for help on social media.答案：C) By selling lemonade and pictures.News 2：Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years, with the goal of providing cheap, renewable energy to five million people.Called “the Wattway,” the roads will be built through joint efforts with the French road-building company Colas and the National Institute of Solar Energy. The company spent the last five years developing solar panels that are only about a quarter of an inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roads more slippery. The panels are also designed so that they can be installed directly on top of existing roadways, making them relatively cheap and easy to install.France isn’t the first country to kick around the idea of paving its roads with solar panels. In November 2015, the Netherlands completed a 229-foot-long bike path paved with solar panels as a test for future projects. However, this is the first time a panel has been designed to be laid directly on top of existing roads and the first project to install the panels on public highways.Questions 3 and 4 are based on the news report you have just heard.Q3： What was France's purpose of constructing the Wattway?A)Finding cheaper ways of highway construction.B)Generating electric power for passing vehicles.C)Providing clean energy to five million people.D)Testing the efficiency of the new solar panel.答案：C) Providing clean energy to five million people.Q4： What is special about the solar panels used in the Wattway?A)They can stand the wear and tear of natural elements.B)They can be laid right on top of existing highways.C)They can only about half an inch thick.D)They are made from cheap materials.答案：B) They can be laid right on top of existing highways.News 3：Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. Continuous fighting in the region has made surveys difficult.But scientists released a report Monday documenting, with hard evidence, the discovery of "lost lions."A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in the National Park in northwest Ethiopia, on the Ethiopia-Sudan border. The researchers set out six camera traps capturing images of lions, and they identified lion tracks.The scientists concluded that lions are also likely to live in the neighbouring National Park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.Questions 5 and 7 are based on the news report you have just heard.Q5： What has made it difficult to survey lions in remote parts in Sudan and Ethiopia?A)Endless fighting in the region.B)The hazards from the desert.C)Inadequate funding for research.D)The lack of clues about the species.答案：A) Endless fighting in the region.Q6： What was the main purpose of the research?A)To observe the wildlife in the two national parks.B)To identify the reasons for the lions’ disappearance.C)To study the habitat of lions in Sudan and Ethiopia.D)To find evidence of the existence of the “lost lions”.答案：D) To find evidence of the existence of the "lost lions".Q7： What did the researchers find in the National Park?A) Lions walking. C) Some camping facilities.B) Lion’s tracks. D) Traps set by local hunters.答案：B) Lions' tracks.Section BDirections： In this section, you will hear two long conversations. At the end of each conversation, you will hear four questions. Both the conversation and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D). Then mark the corresponding letter on Answer sheet 1 with a single line through the centre.Passage 1M： I bet you're looking forward to the end of this month. Are you?W： Yes, I am. How did you know?M： David told me you had a special birthday coming up.W：Oh…yeah that's right. This year will be my golden birthday.M： What does that mean? I've never heard of a golden birthday.W： I've actually just learnt this concept myself. Fortunately, just in time to celebrate. A golden or lucky birthday is when one turns the age of their birth date. So,for example, my sister's birthday is December 9th and her golden birthday would have been the year she turned nineyears old. Come to think of it, my parents did throw her a surprise party that year.M： Interesting. Too bad I missed mine. My golden birthday would've been four years ago. I assume you got big plans then.W： Actually yes. My husband is planning a surprise holiday for the two of us next week. I have no idea what he's got in mind, but I'm excited to find out. Has he mentioned anything to you?M： He might have.W： Anything you'd like to share? I'm dying to know what kind of trip he has planned on where we're going.M： You know nothing at all?W：Not a clue. Hard to imagine, isn’t it? Though I must say I think he's been having even more fun keeping the secret from me in the past few weeks.M： I'm sure both of you will have a fantastic time. Happy golden birthday! I can't wait to hear all about it when you get back.Questions 8 to 11 are based on the conversation you have just heard.Q8. What is the woman looking forward to?A) Her ‘lucky birthday’ C) Her wedding anniversary.B) A call from her dad. D) A special gift from the man.答案：A) Her 'lucky birthday'.Q9. What did the woman's parents do on her sister'slucky birthday?A) Gave her a big model plane. C) Took her on a trip overseas.B) Bought her a gold necklace. D) Threw her a surprise party.答案：D) Threw her a surprise party.Q10. What is the woman eager to find out about?A) The gift her husband has bought.B) The trip her husband has planned.C) What has been troubling her husband.D) What her husband and the man are up to.答案：B) The trip her husband has planned.Q11. What does the man say at the end of the conversation?A) He will be glad to be a guide for the couple’s holiday trip.B) He will tell the woman the secret if her husband agrees.C) He is eager to learn how the couple’s holiday turns out.D) He wants to find out about the couple’s holiday plan.答案： C) He is eager to learn how the couple's holiday turns out.Passage 2W： Mr. Green, what do you think makes a successful negotiator?M：Well, that’s hard to define. But I think successful negotiators have several things in common. They are always polite and rational people. They are firm but flexible. They can recognize power and know how to use it. They aresensitive to the dynamics of the negotiation. The way ofrises and falls and how it may change direction. They project the image of confidence, and perhaps most importantly, they know when to stop.W： And, what about an unsuccessful negotiator?M： Well, this is probably all of us when we start out. We are probably immature and over-trusting. Too emotional or aggressive. We are unsure of ourselves and we want to beliked by everyone. Good negotiators learn fast. Poor negotiators remain like that and go on losing negotiations.W： In your opinion, can the skills of negotiation be taught?M： Well, you can teach someone how to prepare for a negotiation. There are perhaps six stages in every negotiation. Get to know the other side. State your goals. Start the process. Clarify areas of disagreement or conflict. Reassess your position. Making acceptable compromises. And finally, reach some agreement in principle. These stages canbe studied. And strategies to be used in each can be planned beforehand. But I think, the really successful negotiator is probably born with six sense about responding appropriatelyto the situation at hand.W：The artistic sense you’ve just described?M：Yes. That’s rig ht.Questions 12 to 15 are based on the conversation you have just heard.Q12： What does the man say about good negotiators?A) They are sensitive to the dynamics of a negotiation.B) They see the importance of making compromises.C) They know when to adopt a tough attitude.D) They take the rival’s attitude into account.答案：A) They are sensitive to the dynamics of a negotiation.Q13： What does the man say may be the most important thing to a successful negotiator?A) They know how to adapt. C) They know when to make compromises.B) They know when to stop. D) They know how to control their emotion.答案：B) They know when to stop.Q14： How is a good negotiator different from a poor one?A) They are patient. C) They learn quickly.B) They are good at expression. D) They uphold their principles.答案： C) They learn quickly.Q15： What is the first stage of negotiation according to the man?A) Make clear one’s intentions. C) Formulate one’s strategy.B) Clarify items of negotiation. D) Get to know the other side.答案：D) Get to know the other side.Section CDirections： In this section, you will hear three passages. At the end of each passage, you will hear three or four questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C), D). Then mark the corresponding letter on Answer Sheet 1 with a single line through the centre.Passage 1Some people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on Earth. Actually space technology helps people on Earth every day. This is called "spin-off technology."Spin-off technology is space technology that is now used on Earth.In early space programs, such as the Apollo missions of the 1960s and 1970s, and in the Space Shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day.For example, we have Quartz crystal clocks and watches accurate to within one minute a year. We purify the water we drink with a water filter designed for the astronauts' use in space.The cordless, hand-held tools we use in our homes, such as vacuum cleaners, flashlights, drills and saws came fromthe technology of these early space programs.On cold winter days we can stay warm with battery-operated gloves and socks, and specially made coats and jackets. All of these clothes are similar to the spacesuit designs that kept astronauts comfortable in the temperatures of the moon, and are spin-offs from space technology.These products are only a few examples of the many ways space technology helps us in our everyday lives. No one knows how new spin-off technology from the International Space Station will help us in the future.Questions 16 to 18 are based on the passage you havejust heard.Q16： What do some people want to know about space exploration?A) When America’s earliest space program started.B) When the International Space Station was built.C) How many space shuttle missions there will be.D) How space research benefits people on Earth.答案： D) How space research benefits people on Earth.Q17： What did scientists do for the space shuttle missions?A) They accurately calculated the speed of the orbiting shuttles.B) They developed objects for astronauts to use in outer space.C) They tried to meet astronauts’ specific requirements.D) They tried to make best use of the latest technology.答案：B) They developed objects for astronauts to use in outer space.Q18： What does the speaker say about Quartz crystal clocks and watches?A) They are extremely accurate. C) They were first made in space.B) They are expensive to make. D) They were invented in the 1970s.答案：A) They are extremely accurate.Passage 2Well, if I could go back in history and live, I'd like to go back to the 18th century and perhaps in colonial America in Yankee, New England, where one of my ancestors lived, because it was the beginning of something.By the 18th century, there was a feeling of community that had grown. My ancestor was a preacher, traveling around the countryside. People lived in small communities. There were fishermen and farmers who provided fresh food that tasted and looked like food, unlike that in today's supermarkets, and there were small towns, and New York wasn't that far away. I'm deeply attached to the Puritan tradition, not in a religious sense, but they believed in working for something, working for goals, and I like that.They worked hard at whatever they did, but they had a sense of achievement. They believed in goodness in community and helping one another. I love the colonial fabrics, all the silver work, the furnishings, the combination of elegance and simplicity. I love it. The printing, the books, I'm very attached to all that kind of thing that may not all be very entertaining in the modern sense of the world. But I would have enjoyed spending my evenings in that environment, discussing new ideas, building a new world. And I can see myself sitting on a small chair by the fire doing needlework.Questions 19 to 21 are based on the passage you havejust heard.Q19： Why does the speaker say she would like to go back and live in the 18th century America?A) It was when her ancestors came to America.B) People had plenty of land to cultivate then.C) It marked the beginning of something new.D) Everything was natural and genuine then.答案：C) It marked the beginning of something new.Q20： What does the speaker say about the Puritans?A) They believed in working for goals. C) They had all kinds of entertainment.B) They enjoyed living a life of ease. D) They were known to be creative.20. A) They believed working for goals.答案：What would the speaker like doing if she could go back to the past?21.What would the speaker like doing if she could go back to the past?A)Chatting with her ancestors.B)Furnishing her country house.C)Polishing all the silver work.D)Doing needlework by the fire.答案：D) Doing needlework by the fire.Passage 3If you are lost in the woods, a little knowledge can turn what some people call a hardship into an enjoyable stay away from the troubles of modern society. When you think youare lost, sit down on a log, or a rock, or lean against a tree, and recite something that you have memorized, to bring you mind to a point where it’s under control. Don’t run blindly. If you must move, don’t follow a stream unless you know it, and in that case, you are not lost. Streams, normally flow through wetland before they reach a lake or a river. Though there are more eatable plants, there may also be wild animals, poisonous snakes, and other hazards. Many experts feel that it’s wisest to walk uphill. At the top of most hills and mountains, are trails leading back to civilization. If there are no trails, you are much easier to be seen on top of a hill, and you may even spot a highway, or a railroad from this point. Nowadays, the first way someone will search for you is by air. In a wetland, or in dense growth, you are very hard to spot. Anytime you go into the woods, somebody should know where you are going, and when you expect to return. Also, when someone comes looking, you should be able to signal to them.Questions 22-25 are based on the passage you have just heard.22. What does the speaker advise you to do first if you are lost in the woods?A)Use a map to identify your location.B)Call your family or friends for help.C)Sit down and try to calm yourself.D)Try to follow your footprints back.答案：C) Sit down and try to calm yourself23. What will happen if you follow an unknown stream in the woods?A)You may find a way out without your knowing it.B)You may expose yourself to unexpected dangers.C)You may get drowned in a sudden flood.D)You may end up entering a wonderland.答案： B)You may expose yourself to unexpected dangers.24. What do many experts think is the wisest thing to do if you are lost in the woods?A)Look for food.B)Wait patiently.C)Start a fire.D)Walk uphill.答案：D)Walk uphill.25.

2019年12月大学英语四级听力改革练习题及答案(2)英语四级听力习题：26.A. Watching TV can cause physical diseases.B. TV places the viewer in a completely passive position.C. People are too dependent on TV.D. The quality of some TV programs is poor.27.A. Television has more advantages than disadvantages.B. Television has more disadvantages than advantages.C. It is no use watching TV.D. Television in itself is neither good nor bad.28.A. How much a TV set costs.B. The quality of TV programs.C. How people put it to use.D. The number of people watching TV.英语四级听力材料Television now plays such an important part in so many people's lives that it is essential for us to try to decide whether it is a blessing or a curse. Obviously television hasboth advantages and disadvantages. But do the former outweigh the latter? In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. They just sit comfortably at home and enjoy endless series of programs rather than to go out in search of amusement elsewhere. Some people, however, maintain that this is precisely where the danger lies. The television viewer needs to do nothing. [26]He is completely passive and has everything presented to him without any effort on his part. Secondly, television keeps one informed about current events, allows one to follow the latest developments in science and politics. Yet here again there is a danger. The television screen itself has a terrible, almost physical fascination for us. [26]We get so used to looking at its movements, so dependent on its pictures that it begins to dominate our lives. There are many other arguments for and against television. [26]The poor quality of its program is often criticized. But it is undoubtedly a great comfort to many lonely elderly people. And does it corrupt or instruct our children? [27]I think we must realize that television initself is neither good nor bad. [28]It is the uses to whichit is put that determine its value to society.Questions 26 to 28 are based on the passage you have just heard.英语四级听力参考答案：26. Which of the following is NOT mentioned as the disadvantages of TV?准确答案：A解析：本文分析电视的利弊，它带来益处的同时也有潜在的弊端。

2019年12月大学英语四级听力改革练习题及答案(5)

2019年12月大学英语四级听力改革练习题及答案(5)英语四级听力习题：26.A. To know their business partner better.B. To enjoy the dishes only.C. To have a relaxation.D. To escape from the company.27.A. It must be something unusual.B. It's a business appointment.C. It's a hot debate on their life.D. It's a private talk.28.A. Because they would admire her for having so many clients.B. Because she doesn't want to dine far from the office.C. Because she doesn't care what people think of her.D. Because they would believe she is doing business.英语四级听力材料In the world of business, it is not always easy for women to do the same things as men. Consider the working dinner.In order to do your job well, it's important to sometimes see clients and business contacts away from the office. [26]In a more relaxed atmosphere, you can get to know your business partner better. In the end, after all, people do business with people they like.Women start out at a disadvantage because it's tough to invite men out for a game of golf or tennis. Men usually prefer to play sports with other men.You might think that restaurants are the perfect playing field. But they can be dangerous ground. [27]If people from the office see two men they know having dinner together, they think it's business. If colleagues see a woman dining with a man, they often wonder if it's another kind of business.One answer is to take another colleague or client to dinner. Of course, this isn't always convenient.

Each passage is followed by some questions or unfinished statements. For each of them there are four choicesmarked A), B), C) and D). You should decide on the best choice and markthe corresponding letter on the Answer Sheet with a single line through thecentre.Passage OneQuestions 21 to 25 are based on the following passage.I’m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today’s children aresignificantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America’s kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in community, among other things—and a growing perception that the world is a more dangerous place.Given that we can’t turn the clock back, adults can still do plenty to help the next generation cope.At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of virtual (虚拟的) violence your children are exposed to. It’s not just video games and movies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn’t have to ruin your life.21. The author thinks that the conclusions of any research about people’s state of mindare ________.A) surprisingB) confusingC) illogicalD) questionable22. What does the author mean when he says, “we can’t turn the clock back” (Line 1,Para. 3)?A) It’s impossible to slow down the pace of change.B) The social reality children are facing cannot be changed.C) Lessons learned from the past should not be forgotten.D) It’s impossible to forget the past.23. According to an analysis, compared with normal children today, children treated asmentally ill 50 years ago ________.A) were less isolated physicallyB) were probably less self-centeredC) probably suffered less from anxietyD) were considered less individualistic24. The first and most important thing parents should do to help their children is________.A) to provide them with a safer environmentB) to lower their expectations for themC) to get them more involved sociallyD) to set a good model for them to follow25. What conclusion can be drawn from the passage?A) Anxiety, though unavoidable, can be coped with.B) Children’s anxiety has been enormously exaggerated.C) Children’s anxiety can be eliminated with more parental care.D) Anxiety, if properly controlled, may help children become mature.Passage TwoQuestions 26 to 30 are based on the following passage.It is easier to negotiate initial salary requirement because once you are inside, the organizational constraints (约束) influence wage increases. One thing, however, is certain: your chances of getting the raise you feel you deserve are less if you don’t at least ask for it. Men tend to ask for more, and they get more, and this holds true with other resources, not just pay increases. Consider Beth’s story:I did not get what I wanted when I did not ask for it. We had cubicle (小隔间) offices and window offices. I sat in the cubicles with several male colleagues. One by one they were moved into window offices, while I remained in the cubicles, several males who were hired after me also went to offices. One in particular told me he was next in line for an office and that it had been part of his negotiations for the job. I guess they thought me content to stay in the cubicles since I did not voice my opinion either way.It would be nice if we all received automatic pay increases equal to our merit, but “nice” isn’t a quality attributed to most organizations. If you feel you deserve a significant raise in pay, you’ll probably have to ask for it.Performance is your best bargaining chip (筹码) when you are seeking a raise. You must be able to demonstrate that you deserve a raise. Timing is also a good bargaining chip. If you can give your boss something he or she needs (a new client or a sizable contract, for example) just before merit pay decisions are being made, you are more likely to get the raise you want.Use information as a bargaining chip too. Find out what you are worth on the open market.What will someone else pay for your services?Go into the negotiations prepared to place your chips on the table at the appropriate time and prepared to use communication style to guide the direction of the interaction.26. According to the passage, before taking a job, a person should ________.A) demonstrate his capabilityB) give his boss a good impressionC) ask for as much money as he canD) ask for the salary he hopes to get27. What can be inferred from Beth’s story?A) Prejudice against women still exists in some organizations.B) If people want what they deserve, they have to ask for it.C) People should not be content with what they have got.D) People should be careful when negotiating for a job.28. We can learn from the passage that ________.A) unfairness exists in salary increasesB) most people are overworked and underpaidC) one should avoid overstating one’s performanceD) most organizations give their staff automatic pay raises29. To get a pay raise, a person should ________.A) advertise himself on the job marketB) persuade his boss to sign a long-term contractC) try to get inside information about the organizationD) do something to impress his boss just before merit pay decisions30. To be successful in negotiations, one must ________.A) meet his boss at the appropriate timeB) arrive at the negotiation table punctuallyC) be good at influencing the outcome of the interactionD) be familiar with what the boss likes and dislikesPassage ThreeQuestions 31 to 35 are based on the following passage.When families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma’s generation. Their tables will be set with the good dishes andsilver, and the dress code will be Sunday-best.But in many other homes, this china-and-silver elegance has given way to a stoneware (粗陶)-and-stainless informality, with dresses assuming an equally casual-Friday look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it spells economic hard times.Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is eliminating 1,000 jobs—one-fifth of its total workforce. That brings to more than 4,000 the number of positions lost in 18 months in the pottery (陶瓷) region. Wedgwood and other pottery factories made cuts earlier.Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts. A spokesman for Royal Doulton admitted that the com pany “has been somewhat slow in catching up with the trend” toward casual dining. Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television;Even dinner parties, if they happen at all, have gone casual. In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it’s better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a “real” dinner party. Too often, the perfect moment never comes. Iron a fine-patterned tablecloth? Forget it. Polish the silver? Who has time?Yet the loss of formality has its down side. The fine points of etiquette (礼节) that children might once have learned at the table by observation or instruction from parents and grandparents (“Chew with your mouth closed.” “Keep your elbows off the table.”) must be picked up elsewhere. Some companies now offer etiquette seminars for employees who may be competent professionally but clueless socially.31. The trend toward casual dining has resulted in ________.A) bankruptcy of fine china manufacturersB) shrinking of the pottery industryC) restructuring of large enterprisesD) economic recession in Great Britain32. Which of the following may be the best reason for casual dining?A) Family members need more time to relax.B) Busy schedules leave people no time for formality.C) People want to practice economy in times of scarcity.D) Young people won’t follow the etiquette of the older generation.33. It can be learned from the passage that Royal Doulton is ________.A) a retailer of stainless steel tablewareB) a dealer in stonewareC) a pottery chain storeD) a producer of fine china34. The main cause of the layoffs in the pottery industry is ________.A) the increased value of the poundB) the economic recession in AsiaC) the change in people’s way of lifeD) the fierce competition at home and abroad35. Refined table manners, though less popular than before in current social life________.A) are still a must on certain occasionsB) axe bound to return sooner or laterC) are still being taught by parents at homeD) can help improve personal relationshipsPassage FourQuestions 36 to 40 are based on the following passage.Some houses are designed to be smart. Others have smart designs. An example of the second type of house won an Award of Excellence from the American Institute of Architects.Located on the shore of Sullivan’s Island off the coast of South Carolina, th e award-winning cube-shaped beach house was built to replace one smashed to pieces by Hurricane (飓风) Hugo 10 years ago. In September 1989, Hugo struck South Carolina, killing 18 people and damaging or destroying 36,000 homes in the state.Before Hugo, many new houses built along South Carolina’s shoreline were poorly constructed, and enforcement of building codes wasn’t strict, according to architect Ray Huff, who created the cleverly-designed beach house. In Hugo’s wake, all new shoreline houses are required to meet stricter, better-enforced codes. The new beach house on Sullivan’s Island should be able to withstand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour.At first sight, the house on Sullivan’s Island looks anything but hur ricane-proof. Its redwood shell makes it resemble “a large party lantern (灯笼)” at night, according to one observer. But looks can be deceiving. The house’s wooden frame is reinforced with long steel rods to give it extra strength.To further protect the house from hurricane damage, Huff raised it 2.7 meters off the ground on timber pilings—long, slender columns of wood anchored deep in the sand. Pilings might appear insecure, but they are strong enough to support the weight of the house. They also elevate the house above storm surges. The pilings allow the surges to run under the house instead of running into it. “These swells of water come ashore attremendous speeds and cause most of the damage done to beach-front buildings,” said Huff.Huff designed the t imber pilings to be partially concealed by the house’s ground-to-roof shell. “The shell masks the pilings so that the house doesn’t look like it’s standing with its pant legs pulled up,” said Huff. In the event of a storm surge, the shell should break apart and let the waves rush under the house, the architect explained.36. After the tragedy caused by Hurricane Hugo, new houses built along SouthCarolina’s shore line are required ________.A) to be easily reinforcedB) to look smarter in designC) to meet stricter building standardsD) to be designed in the shape of cubes37. The award-winning beach house is quite strong because ________.A) it is strengthened by steel rodsB) it is made of redwoodC) it is in the shape of a shellD) it is built with timber and concrete38. Huff raised the house 2.7 meters off the ground on timber pilings in order to________.A) withstand peak winds of about 200 km/hrB) anchor stronger pilings deep in the sandC) break huge sea waves into smaller onesD) prevent water from rushing into the house39. The main function of the shell is ________.A) to strengthen the pilings of the houseB) to give the house a better appearanceC) to protect the wooden frame of the houseD) to slow down the speed of the swelling water40. It can be inferred from the passage that the shell should be ________.A) fancy-lookingB) waterproofC) easily breakableD) extremely strongPart III Vocabulary (20 minutes)Directions: There are 30 incomplete sentences in this part.

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 Sheet2.A South Korean city designed for the future takes on a life of its ownA) Getting around a city is one thing - and then there’s the matter of getting from one city toanother. One vision of the perfect city of the future: a place that offers easy access to air travel.In 2011, a University of North Carolina business professor named John Kasarda published a book called Aerotropolis: The Way We’ll Live Next. Kasarda says future cities should be built intentionally around or near airports. The idea, as he has put it, is to of fer businesses “rapid, long-distance connectivity on a massive scale.”B) “The 18th century really was a waterborne (水运的) century, the 19th century a rail century. the 20th century a highway, car, truck century一and the 21st century will increasingly be an aviation century, as the globe becomes increasingly connected by air,”Kasarda says. Songdo, a city built from scratch in South Korea, is one of Kasarda’s prime examples. It has existed for just a few years.“ From the get-go, it was designed on the basis of connectivity and competitiveness,”says Kasada. “The government built the bridge directly from the airport to the Songdo International Business District. And the surface infrastructure was built in tandem with the new airport.”C) Songdo is a stone’s throw from South Korea’s Incheon Airport, its main international hub (枢纽). But it takes a lot more than a nearby airport to be a city of the future. Just building a place as an “international business district”doesn’t mean it will become one. Park Yeon Soo conceived (构想) this city of the future back in 1986. He considers Songdo his baby. “I am a visionary,”he says. Thirty years after he imagined the city, Park’s baby is close to 70 percent built, with 36.000 people living in the business district and 90,000 residents in greater Songdo. It’s about an hour outside Seoul, built on reclaimed tidal flats along the Yellow Sea, There’s a Coast Guard building and a tall trade tower, as well as a park, golf course and university.D) Chances are you’ve actually se en this place. Songdo appears in the most famous music video ever to come ou of South Korea. “Gangnam Style” refers to the fashionable Gangnam district in Seoul. But some of the video was filmed in Songdo.“I don’t know if you remember, there was a scene in a subway station. That was not Gangnam. That was actually Songdo,” says Jung Won Son, a professor of urban development at London’s Bartlett School of Planning, “Part of the reason to shoot there is that it’s new and nice.”E) The city was supposed to be a hub for global companies, with employees from all over the world. But hat’s not how it has turned out. Songdo’s reputation is as a futuristic ghost town. But the reality is more complicated. A bridge with big, light-blue loops leads into the business district. In the center of the main road, there’s a long line of flags of the world. On the corner, there’s a Starbucks and a 7-Eleven--all of the international brands that you see all over the world nowadays.F) The city is not empty. There are mothers pushing strollers, old women with walkers -- even in the middle of the day. when it’s 90 degrees out. Byun Young-Jin chairs the Songdo real estate association and started selling property here when the first phase of the city opened in 2005. He says demand has boomed in the past couple of years. Most of his clients are Korean. In fact, the developer says, 99 percent of the homes here are sold to Koreans. Young families move here because the schools are great. And that’s the problem: Songdo has become a popular Koreancity 一more popular as a residential area than a business one. It’s not yet the futuristic international business hub that planners imagined. “It’s a great place to live. And it’s becoming a great place to work,”says Scott Summers, the vice president of Gale International, the developer of the city. The floor-to-ceiling windows of his company’s offices overlook Songdo Central Park, with a canal full of kayaks and paddle boats. Shimmering (闪烁的) glass towers line the canal’s edge.G) “What’s happen ed is, because we focused on creating that quality of life first, which enabled the residents to live here, what has probably missed the mark is for companies to locate here,” he says. “There needs to be strong economic incentives.” The city is still unfin ished, and it feels a bit like a theme park. It doesn’t feel all that futuristic. There’s a high-tech underground trash disposal system. Buildings are environmentally friendly. Everybody’s television set is connected to a system that streams personalized language or exercise classes.H) But Star Trek this is not. And to some of the residents, Songdo feels hollow. “I’m, like, in prison for weekdays. That’s what we call it in the workplace,” says a woman in her 20s. She doesn’t want to use her name for fear of being fired from her job. She goes back to Seoul every weekend. “I say I’m prison-breaking on Friday nights.” But she has to make the prison break in her own car. There’s no high-speed train connecting Songdo to Seoul, just over 20 miles away.I) The man who first imagined Songdo feels frustrated. too. Park says he built South Korea a luxury vehicle, “like Mercedes or BMW. It’s a good car now. But we’re waiting for a good driver to accelerate.” But there are lots of other good cars out there, too. The world is dotted with futuristic, high-tech cities trying to attract the biggest international companiesJ) Songdo’s backers contend that it’s still early, and business space is filling up-about 70 percent of finished offices are now occupied. Brent Ryan, who teaches urban design at MIT, says Songdo proves a universal principle. “There have been a lot of utop ian (乌托邦的) cities in history. And the reason we don’t know about a lot of them is that a lot of them have vanished entirely.”In other words, when it comes to cities-or anything else-it is hard to predict the future.第36题Songdo’s popularity lies more in its quality of life than its business attraction._______第37题The man who conceives Songdo feels disappointed because it has fallen short of his expectations._______第38题A scene in a popular South Korean music video was shot in Songdo._______第39题Songdo still lacks the financial stimulus for businesses to set up shop there._______第40题Airplanes will increasingly become the chief means of transportation, according to a professor._______第41题Songdo has ended up different from the city it was supposed to be._______第42题Some of the people who work in Songdo complain about boredom in the workplace. _______第43题A business professor says that a future city should have easy access to international transportation._______第44题Acording to an urban design professor, it is difficult for city designers to foresee what happen in the future._______第45题Park Yeon So. Who envisioned Songdo, feels a parental connection with the city._______上一题下一题(46~50/共30题)Part ⅢReading Comprehension(40 minutes)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.The fifth largest city in the US passed a significant soda tax proposal that will levy (征税)1.5 cents per liquid ounce on distributors.Philadelphia’s new measure was approved by a 13 to 4 city council vote. It sets a new bar for similar initiatives across the county. It is proof that taxes on sugary drinks can win substantial support outside super-liberal areas. Until now, the only city to successfully pass and implement a soda tax was Berkeley, California, in 2014.The tax will apply to regular and diet sodas, as well as other drinks with added sugar, such as Gatorade and iced teas. It’s expected to raise $410 million over the next five years, most of which will go toward funding a universal pre-kindergarten program for the city.While the city council vote was met with applause inside the council room, opponents to the measure, including soda lobbyists made sharp criticisms and a promise to challenge the tax in court.“The tax passed today unfairly singles out beverages-including low- and no-calorie choices,” said Lauren Kane, spokesw oman for the American Beverage Association. “But most importantly, it is against the law. So we will side with the majority of the people of Philadelphia who oppose this tax and take legal action to stop it.”An industry backed anti-tax campaign has spent at least $4 million on advertisements. The ads criticized the measure. characterizing it as a“grocery tax.”Public health groups applauded the approved tax as a step toward fixing certain lasting health issues that plague Americans. “The move to recapture a small part of the profits from an industry that pushes a product that contributes to diabetes, obesity and heart disease in poorer communities in order to reinvest in those communities will sure be inspirational to many other places,” said Jim Krieger, executive director of Healthy Food America. “Indeed, we are alreadyhearing from some of them. It’s not just Berkeley’ anymore.”Similar measures in California’s Albany, Oakland, San Francisco and Colorado’s Boulder are becoming hot-button issues Health advocacy groups have hinted that even more might be coming.第46题What does the passage say about the newly-approved soda tax in Philadelphia?A.It will change the lifestyle of many consumers.B.It may encourage other US cities to follow suit.C.It will cut soda consumption among low-income communities.D.It may influence the marketing strategies of the soda business.第47题What will the opponents probably do to respond to the soda tax proposal?A.Bargain with the city council.B.Refuse to pay additional tax.C.Take legal action against it.D.Try to win public support.第48题What did the industry-backed anti-tax campaign do about the soda tax proposal?A.It tried to arouse hostile feelings among consumers.B.It tried to win grocers’ support against the measure.C.It kept sending letters of protest to the media.D.It criticized the measure through advertising.第49题What did public health groups think the soda tax would do?A.Alert people to the risk of sugar-induced diseases.B.Help people to fix certain long-time health issues.C.Add to the fund for their research on diseases.D.Benefit low-income people across the country.第50题What do we learn about similar measures concerning the soda tax in some other cities?A.They are becoming rather sensitive issues.B.They are spreading panic in the soda industry.C.They are reducing the incidence of sugar-induced diseases.D.They are taking away lot of profit from the soda industry.上一题下一题(51~55/共30题)Part ⅢReading Comprehension(40 minutes)Passage TwoQuestions 51 to 55 are based on the following passage.Popping food into the microwave for a couple of minutes may seem utterly harmless, but Europe’s stock of these quick-cooking ovens emit as much carbon as nearly 7 million cars, a new study has found. And the problem is growing. With costs falling and kitchen appliances becoming “status” items, owners are throwing away microwaves after an average of eight years. This is pushing sales of new microwaves which are expected to reach 135 million annually in the EU by。

That is the 26 of a new study that looked at how respiratory (呼吸道) viruses 27 on airplanes. Researchers found that only people who were seated in the same row as a passenger with the flu, for example – or one row in front of or behind that individual –had a high risk of catching the illness. All other passengers had only a very 28 chance of getting sick, according to the findings. Media reports have not necessarily presented 29 information about the risk of getting infected on an airplane in the past. Therefore, these new findings should help airplane passengers to feel less 30 to catching respiratory infections while traveling by air.Prior to the new study, little was known about the risks of getting 31 infected by common respiratory viruses, such as the flu or common cold, on an airplane, the researchers said. So,to 32 the risks of infection, the study team flew on 10 different 33 in the U.S. during the flu season. The researchers found that passengers sitting within two seats on 34 side of a person infected with the flu, as well as those sitting one row in front of or behind this individual, had about an 80 percent chance of getting sick. But other passengers were 35 safe from infection. They had a less than 3 percent chance of catching the flu.A) accurateB) conclusionC) directlyD) eitherE) evaluateF) explorationsG) flightsH) largely I) nearbyJ) respond K) slimL) spread M) summit N) vividly O) vulnerableSection BDirections: In this section, you are going to read a passage with ten statements attached to it. 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 correspondingletter on Answer Sheet 2.Is Breakfast Really the MostImportant Meal of the Day?A) Along with old classics like “carrots give you night vision” and “Santa doesn’t bring toys to misbehaving children”, one of the most well-worn phrases of tired parents everywhere is that breakfast is the most important meal of the day. Many of us grow up believing that skipping breakfast is a serious mistake, even if only two thirds of adults in the UK eat breakfast regularly, according to the British Dietetic Association, and around three-quarters of Americans.B) “The body uses a lot of energy stores for growth and repair through the night,” explains diet specialist Sarah Elder. “Eating a balanced breakfast helps to up our energy, as well as make up for protein and calcium used throughout the night.” But there’s widespread disagreement over whether breakfast should keep its top spot in the hierarchy (等级) of meals. There have been concerns around the sugar content of cereal and the food indust ry’s involvement in pro-breakfast research –and even one claim from an academic that breakfast is “dangerous”.C) What’s the reality? Is breakfast a necessary start to the day or a marketing tactic by cereal companies? The most researched aspect of breakfast (and breakfast-skipping) has been its links to obesity. Scientists have different theories as to why there’s a relationship between the two. In one US study that analysed the health data of 50,000 people over seven years, researchers found that those who made breakfast the largest meal of the day were more likely to have a lower body mass index (BMI) than those who ate a large lunch or dinner. The researchers argued that breakfasthelps reduce daily calorie intake and improve the quality of our diet – since breakfast foods are often higher in fibre and nutrients.D) But as with any study of this kind, it was unclear if that was the cause – or if breakfast-skippers were just more likely to be overweight to begin with. To find out, researchers designed a study in which 52 obese women took part in a 12-week weight loss programme. All had the same number of calories over the day, but half had breakfast, while the other half did not. What they found was that it wasn’t breakfast itself that caused the participa nts to lose weight: it was changing their normal routine.E) If breakfast alone isn’t a guarantee of weight loss, why is there a link between obesity and breakfast -skipping? Alexandra Johnstone, professor of appetite research at the University of Aberdeen, argues that it may simply be because breakfast-skippers have been found to be less knowledgeable about nutrition and health. “There are a lot of studies on the relationship between breakfast eating and possible health outcomes, but this may be because those who eat breakfast choose to habitually have health-enhancing behaviours such as regular exercise and not,” she says.F) A 2016 review of 10 studies looking into the relationship between breakfast and weight management concluded there is “limited evidence” supporting or refuting (反驳) the argument that breakfast influences weight or food intake, and more evidence is required before breakfast recommendations can be used to help prevent obesity.G) Researchers from the University of Surrey and University of Aberdeen are halfway through research looking into the mechanisms behind how the time we eat influences body weight. Early findings suggest that a bigger breakfast is beneficial to weight control. Breakfast has been found to affect more than just weight. Skipping breakfast has been associated with a 27% increased risk of heart disease, a 21% higher risk of type 2 diabetes in men, and a 20% higher risk of type 2 diabetes in women. One reason may be breakfast’s nutritional value – partly because cereal is fortified (增加营养价值) with vitamins. In one study on the breakfast habits of 1,600 young people in the UK, researchers found that the fibre and micronutrient intake was better in those who had breakfast regularly. There have been similar findings in Australia, Brazil, Canada and the US.H) Breakfast is also associated with improved brain function, including concentration and language.A review of 54 studies found that eating breakfast can improve memory, though the effects on other brain functions were inconclu sive. However, one of the review’s researchers, Mary Beth Spitznagel, says there is “reasonable” evidence breakfast does improve concentration – there just needs to be more research. “Looking at studies that tested concentration, the number of studies show ing a benefit was exactly the same as the number that found no benefit,” she says. “And no studies found that eating breakfast was bad for concentration.”I) What’s most important, some argue, is what we eat for breakfast. High-protein breakfasts have been found particularly effective in reducing the longing for food and consumption later in the day, according to research by the Australian Commonwealth Scientific and Industrial Research Organisation. While cereal remains a firm favourite among breakfast consumers in the UK and US, a recent investigation into the sugar content of ‘adult’ breakfast cereals found that some cerealscontain more than three-quarters of the recommended daily amount of free sugars in each portion, and sugar was the second or third highest ingredient in cereals.J) But some research suggests if we’re going to eat sugary foods, it’s best to do it early. One study recruited 200 obese adults to take part in a 16-week-long diet, where half added dessert to their breakfast, and half didn’t. Those who added dessert lost an average of 40 pounds more – however, the study was unable to show the long-term effects. A review of 54 studies found that there is no consensus yet on what type of breakfast is healthier, and concluded that the type of breakfast doesn’t matter as much as simply eating something.K) While there’s no conclusive evidence on exactly what we should be eating and when, the consensus is that we should listen to our own bodies and eat when we’re hungry. “Breakfast is most importan t for people who are hungry when they wake up,” Johnstone says. “Each body starts the day differently –and those individual differences need to be researched more closely,” Spitznagel says. “A balanced breakfast is really helpful, but getting regular meal s throughout the day is more important to leave blood sugar stable through the day, which helps control weight and hunger levels,” says Elder. “Breakfast isn’t the only meal we should be getting right.”36. According to one professor, obesity is related to a lack of basic awareness of nutrition and health.37. Some scientists claim that people should consume the right kind of food at breakfast.38. Opinions differ as to whether breakfast is the mist important meal of the day.39. It has been found that not eating breakfast is related to the incidence of certain diseases in some countries.40. Researchers found it was a change in eating habits rather than breakfast itself that induced weight loss.41. To keep oneself healthy, eating breakfast is more important than choosing what to eat.42. It is widely considered wrong not to eat breakfast.43. More research is needed to prove that breakfast is related to weight loss or food intake.44. People who prioritise breakfast tend to have lower calorie but higher nutritional intake.45. Many studies reveal that eating breakfast helps people memorise and concentrate.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.Textbooks represent an 11 billion dollar industry, up from $8 billion in 2014. Textbook publisher Pearson is the largest publisher – of any kind – in the world.It costs about $1 million to create a new textbook. A freshman textbook will have dozens of contributors, from subject-matter experts through graphic and layout artists to expert reviewers and classroom testers. Textbook publishers connect professors, instructors and students in ways that alternatives, such as open e-textbooks and open educational resources, simply do not. This connection happens not only by means of collaborative development, review and testing, but also at conferences where faculty regularly decide on their textbooks and curricula for the coming year.It is true that textbook publishers have recently reported losses, largely due to students renting or buying used print textbooks. But this can be chalked up to the excessively high cost of their books –which has increased over 1,000 percent since 1977. A restructuring of the textbook industry may well be in order. But this does not mean the end of the textbook itself.While they may not be as dynamic as an iPad, textbooks are not passive or lifeless. For example, over the centuries. they have simulated (模拟) dialogues in a number of ways. From 1800 to the present day, textbooks have done this by posing questions for students to answer inductively (归纳性地). That means students are asked to use their individual experience to come up with answers to general questions. Today’s psychology texts, for example, ask: “How much of your personality do you think you inherited?” while ones in physics say: “How can you predict where the ball you tossed will land?”Experts observe that “textbooks come in layers, something like an onion.” For an active learner, engaging with a textbook can be an interactive experience. Readers proceed at their own pace. They “customize” their books by engaging with different layers and linkages. Highlighting, Post-It notes, dog-ears and other techniques allow for further customization that students value in print books over digital forms of books.46. What does the passage say about open educational resources?A) They contribute to teaching as much as to learning.B) They don’t profit as much as traditional textbooks do.C) They can’t con nect professors and students as textbooks do.D) They compete fiercely for customers with textbook producers.47. What is the main cause of the publishers’ losses?A) Failure to meet student need.B) Industry restructuring.C) Emergence of e-books.D) Falling sales.48. What does the textbook industry need to do?A) Reform its structures.B) Cut its retail prices.C) Find replacements for printed textbooks.D) Change its business strategy periodically.49. What are students expected to do in the learning process?A) Think carefully before answering each question.B) Ask questions based on their own understanding.C) Answer questions using their personal experience.D) Give answers showing their respective personality.50. What do experts say about students using textbooks?A) They can digitalize the prints easily.B) They can learn in an interactive way.C) They can purchase customized versions.D) They can adapt the material themselves.Passage TwoQuestions 51 to 55 are based on the following passage.When we think of animals and plants, we have a pretty good way of dividing them into two distinct groups: one converts sunlight into energy and the other has to eat food to make its energy.Well, those dividing lines come crashing down with the discovery of a sea slug (海蛞蝓) that’s truly half animal and half plant. It’s pretty incredible how it has managed to hijack the genes of the algae (藻类) on which it feeds.The slugs can manufacture chlorophyll, the green pigment (⾊素) in plants that captures energy from sunlight, and hold these genes within their body. The term kleptoplasty is used to describe the practice of using hijacked genes to create nutrients from sunlight. And so far, this green sea slug is the only known animal that can be truly considered solar-powered, although some animals do exhibit some plant-like behaviors. Many scientists have studied the green sea slugs to confirm that they are actually able to create energy from sunlight.In fact, the slugs use the genetic material so well that they pass it on to their future generations. Their babies retain the ability to produce their own chlorophyll, though they can’t generate energy from sunlight until they’ve eaten enough algae to steal the necessary genes, which they can’t yet produce on their own.“There’s no way on earth that genes from an alga should work inside an animal cell,” says Sidney Pierce from the University of South Florida. “And yet here, they do. They allow the animal to rely on sunshine for its nutrition. So if something happens to their food source, they have a way of not starving to death until they find more algae to eat.The sea slugs are so good at gathering energy from the sun that they can live up to nine months without having to eat any food. They get all their nutritional needs me t by the genes that they’ve hijacked from the algae51. What is the distinctive feature of a sea slug?A) It looks like both a plant and an animal.B) It converts some sea animals into plants.C) It lives half on animals and half on plantsD) It gets energy from both food and sunlight.52. What enables the sea slug to live like a plant?A) The genes it captures from the sea plant algae.B) The mechanism by which it conserves energy.C) The nutrients it hijacks from other species.D) The green pigment it inherits from its ancestors.53. What does the author say about baby sea slugs?A) They can live without sunlight for a long time.B) They can absorb sunlight right after their birth.C) They can survive without algae for quite some time.D) They can produce chlorophyll on their own.54. What does Sidney Pierce say about genes from an alga?A) They are stolen from animals like the sea slug.B) They can’t function unless exposed to sunlight.C) They don’t usually function inside animal cells.D) They can readily be converted to sea slug genes.55. What do we learn about sea slugs from the passage?A) They behave the way most plant species do.B) They can survive for months without eating.C) They will turn into plants when they mature.D) They will starve to death without sunlight.Part IV TranslationDirections: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

参考答案2019.12第三套真题参考范文Dear Jack ,I am delighted to hear that you are going to learn Chinese in a Chinese university. Since you have asked for my advice about choosing which university, I will try to give you some useful suggestions here.It is well known that Peking University is a great place to learn Chinese. There are several factors accounting for this choice and the following are the most typical ones. First and foremost, Peking University is one of the top universities in China and the birthplace of many great minds. Therefore, it can provide high-quality teaching resources, which is essential for a foreigner learner.In addition, Beijing is the capital of China and there are various historic buildings. They provide foreign students a good chance to know Chinese culture and history.I hope you will find these suggestions helpful and wish you all the best.Yours,Li Ming26-30 OADCG 31-35 HKNEF36-40 FIDGB 41-45 EHAJC46-50 BCDBA 51-55 DDABA参考翻译The full name of China's Han ethnic group is made up of family name and given name. One characteristic of the Chinese name is that the family name always comes first, followed by given name. For thousands of years, the father's family name has been passed on from generation to generation. However, it is not uncommon now for a child to have the mother’s family name. Generally speaking, a given name contains one or two Chinese characters, which carries the parents' hope for the kid. Therefore, it's easy to infer from the name what kind of person the parents expect their child to be, or what kind of life to lead. Parents attach great importance to naming their kid as names usually go with them for a whole life.资料来源于网络，大学生资源共享平台收集整理。

2019年12月四级真题及答案2019年12月英语四级听力真题原文及答案News report 11）New York City police captured a cow on the loose in Prospect Park onTuesday after the animal became an attraction for tourists while walking along the streets and enjoying the park facilities. The confused creature and camera-holding humans stared at each other through a fence for several minutes. At other times the cow wandered around the 526 acre park and the artificial grass field normally used for human sporting events. Officers use soccer goals to fence the animal in. However, the cow then moved through one of the nets knocking down a police officer in the process. Police eventually trapped the cow between two vehicles parked on either side of a baseball field’s bench area. An officer then shot an arrow to put it t o sleep. Then officers waited for the drug to take effect. After it fell asleep they loaded the cow into a horse trailer. It was not clear where the cow came from or how it got lost. 2）Police turned it over to the animal control department after they caught it.一头奶牛于周二出现在公园里，警察最终抓住了它并将其送还至动物管理局。

Thoseare a few of the traits of successful science crowdfunding efforts that emerge from arecent study that examined nearly 400 campaigns. But having a large network andsome promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken offin recent years for everything from making movies to building water-saving have tried to tap Internet donors, too, with mixed success. Some raisedmore than twice their goal, but others have fallen short of reaching more modesttargets.To determine what separates science crowdfunding triumphs from failures, ateam led by science communications scholar Mike Schäfer of the University of Zurichin Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report inPublic Understanding of Science. For one, they use a crowdfunding platform thatspecializes in raising money for science, and not just any kind of project. Althoughsites like Kickstarter take all comers, platforms such as Experiment. com,, and Petridish. org only present scientific projects. For another, theypresent the project with a funny video because good visuals and a sense of humorimproved success. Most of them engage with potential donors since projects thatanswered questions from interested donors and posted lab notes fared better. And theytarget a small amount of money. The projects included in the study raised $4000 onaverage, with 30% of projects receiving less than $ 1000. The more money a projectsought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably,the size of a scientist's personal and professional networks, and how muchresearcher promotes a project on his or her own. Those two factors are by far morecritical than the content on the page. Crowdfunding can be part of researchers effortsto reach the public, and people givebecause they feel a connection to the person"who is doing the fundraising- -not necessarily to the science."11/3151. What do we learn about the scientists trying to raise money online for theirprojectsA) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schafer's research of recent crowdfundingcampaignsA) To create attractive content for science websites.^B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaignA) The potential benefit to future generations.为B) Its interaction with prospective donors.C) Its originality in addressing financial issues.$D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfundingprojectsA) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaignA) The ease of access to the content of the webpage.：B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you cre allowed 30 minutes to translate a passage from( 'hinese into English.

The bottle is27 , and the label says “pure water”, but maybe what’s inside is not so28 . Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29 microplastics?That’s the conclusion of a recently 30 study, which analyzed 259 bottles from 11 brands sold in nine countries, 31 an average of 325 plastic particles per liter of water. These microplastics included a 32 commonly known as PET and are widely used in the manufacture of clothing and food and 33 containers. The study was conducted at the State University of New York on behalf of Orb Media, a journalism organization. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.Confronted with this 34 , several bottled-water manufacturers including Nestle and Coco-Cola undertook their own studies using the same methodology.

Answer the questions by marking the corresponding letter on Answer Sheet 2.The Quiet Heroism of Mail Delivery[A] On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colder than Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail delivery temporarily. “Due to this arctic outbreak and concerns for the safety of USPS employees,” USPS announced Wednesday morning, “the Postal Service is suspending delivery Jan. 30 in the following 3-digit ZIP Code locations.” Twelve regions were listed as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extreme weather.

Natural disasters can wreck a community’s infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal.[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a drone caught footage of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area.

According to Rae Ann Haight, the program manager for the national-preparedness office at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith, this was just another day on the job. “I followed my route like I normally do,” Smith told a reporter. “As I’d come across a box that was up but with no house, I checked, and there was mail—outgoing mail—in it.

Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael.

Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to building water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goal, but others have fallen short of reaching more modest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich in Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as , , and only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors since projects that answered questions from interested donors and posted lab notes fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% of projects receiving less than $1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project’s s uccess, m ost notably, the size of a scientist’s personal and professional networks, and how much a researcher promotes a project on his or her own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researc hers’ efforts to reach the public, and people give because “they feel a connection to the person” who is doing the fundraising—not necessarily to the science.51. What do we learn about the scientists trying to raise money online for their projects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schäfer’s research of recent crowdfunding campaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations. B) Its interaction with prospective donors.C) Its originality in addressing financial issues. D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfunding projects?A) They should be small to be successful. B) They should be based on actual needs.C) They should be assessed with great care. D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part ⅣTranslation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

英语四级听力材料
[32]May and June are the months when most American
colleges and universities hold their graduation ceremonies. These ceremonies are a time for family and friends to gather and celebrate a student's completion of an academic degree. Most ceremonies are traditional. The students wear caps and gowns over their clothing. One by one, their names are called. They go to the front, shake hands with school officials and receive a document of some kind. But first they must sit and listen to speeches. Colleges and universities often invite famous guests or former students who have been successful. Schools often want speakers to comment on world events. This Saturday, for example, Senator Hillary Rodham Clinton will speak at the graduation ceremony at the Rensselaer
Polytechnic Institute in Troy, New York. [33]News people are often invited to speak at graduations. So are
entertainers.[34]Actor John Lithgow, a 1967 graduate of Harvard, will speak at the university on June 9th. Then there are speakers like Jon Stewart. He entertains by making fun of the news. His popular program, "The Daily Show," appears on Comedy Central on cable television. Last year, Jon Stewart spoke at the College of William and Mary in Williamsburg, Virginia. He graduated from there in 1984. He did offer some serious advice. He said： "College is something you complete. Life is something you experience. [35]So don't worry about
your grade, or the results or success. Success is defined in
various ways, and you will find it... Love what you do. Get good at it."
Questions 32 to 35 are based on the passage you have just heard.
32. When do most American universities hold their graduation ceremonies?
[C]解析：短文开头说：“5、6月是绝大部分美国大学举行毕业典礼的月份”。

故答案为C。

细节题，问月份。

短文开头处的信息。

听到什么选什么。

33. Who are often invited to speak at the graduation ceremonies?
[C]解析：文中谈到，“常常会邀请新闻人物和艺人在毕业典礼上
致辞”，故选C。

由选项知本题问到某一类人物。

能够边听边做笔记。

根据“听到什么选什么”的原则，能够得到准确选项。

34. Which university did the actor John Lithgow graduate from?
[A]解析：文中提到“演员John Lithgow是哈佛大学1967届毕业生”，根据问题，选A。

35. What advice did Jon Stewart give at the ceremony of
the College of William and Mary?
[A]解析：短文最后引用了Jon Stewart的忠告：“不要为成绩、
分数、成功担心。

成功有着不同的定义，你们会获得成功的。

”其含
义是要乐观向上，故选A。

B、D与Jon的话无关，C说“使你的校园生活丰富多彩”，与本文主旨不符。

本文讨论毕业典礼而不是入学典礼，所以来宾的话重点不会谈大学生活，而是谈毕业后的人生。
