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. What should you do before you go into the woods?A)Inform somebody of your plan.B)Prepare enough food and drink.C)Check the local weather.D)Find a map and a compass.答案：A) Inform somebody of your plan.12月四六级真题答案去哪找？12月16日锁定###四六级频道，超全四级真题及答案考试结束后免费供应，想第一时间查答案的小朋友快来查看！！！！更多四级真题答案请见>>>。

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。

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。

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 to sleep.

According to the park’s manager, Mr. Villiers, the goal is not just to clear up the park. He says visitors are already good at keeping things clean. Instead, he wants to show that nature itself can teach us to take care of the environment. He says that rooks, the chosen birds, are considered to be particularly intelligent. In the right circumstances, they even like to communicate with humans and establish a relationship through play. The birds will be encouraged to clean the park through the use of a small box that delivers a small amount of bird food. Each time, the rook deposits a cigarette end or a small piece of rubbish. So far, visitors to the theme park have been excited to see the birds in action. However, some parents are concerned that it encourages their children to drop litter so they can watch the birds to pick it up. Villiers is not concerned about this criticism. He maintains most of the feedback he has received has been overwhelmingly positive. He hopes now to train more birds Q5: What have six birds been trained to do at a French historical theme park?A) Pick up trash.B) Amuse visitors.C) Deliver messages.D) Play with children.Q6: Why were rooks chosen by the park manager?A) They are especially intelligent.B) They are children’s favorite.C They are quite easy to tame.D) They are clean and pretty.Q7: What is the concern of some parents?A) Children may be harmed by the rooks.B) Children may be tempted to drop litter.C) Children may contract bird diseases.D) Children may overfeed the rooks.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.

What will Science Nation be about?Woman: It will be about science, all sorts of science. Each episode will focus on a different area of science, and tell us what we know, how we know it, and what we still don't know. The show will have one host only, and this will be Professor Susan Paul from Harvard University. She's a great public speaker.Man: So, just to be clear, will the show its format be like that of the documentary?Woman: Kind of. It will be like a documentary in the sense, that it will be non-fiction and fact-based. However, our idea is for it to be also fun and entertaining, something which traditional documentaries aren't so much. Please keep in mind, this will be a new TV show, like nothing ever done before.Man: Okay, so it will be both educational and entertaining, and your audience will be anyone interested in science, right?Woman: That's correct, yes.Man: Right, thank you. So, I think we're more or less clear what the show will be like. Could you please tell us now, what exactly you want from us?Woman: Yes, of course. Basically, what we need from you is financial support. In order to go ahead with this idea, we need 2 million dollars. This will cover the cost of making all 12 shows in the first season for the first year. If the show is a success, we can then look at making a second season for the following year.Q8. What do we learn about the TV show Science Nation?A) It will be produced at Harvard University.B) It will be hosted by famous professors.C) It will cover different areas of science.D) It will focus on recent scientific discoveries.Q9. In what way will the TV show Science Nation differ from traditional documentaries?A)It will be more futuristic.B) It will be more systematic.C) It will be more entertaining.D) It will be easier to understand.Q10. Who will be the intended audience of the TV show Science Nation?A) People interested in science.B) Youngsters eager to explore.C) Children in their early teens.D) Students majoring in science.Q11.

You don’t look very happy.M: I feel like I’m a failure. I can’t seem to do anything very well.W: I wouldn’t say that. You do very well in a lot of things. That presentation you gave last week was excellent.M: Yes, but I have this urge to strive for perfection. I really want to push harder and progress further.W: Well, that’s v ery admirable. But be careful. Overconcern with being perfect can damage our confidence if we never achieve it.M: Yes, I know. I feel awful whenever I make a mistake in whatever I’m trying to do.W: Well, think about it. You can’t make progress without ma king mistakes and learning from them. Thomas Edison, the famous inventor, once said “I’ve not failed. I’ve just found 10,000 ways that won’t work.”M: You may well be right. I guess I should recognize my mistakes and learn the lesson they teach me and move forward.W: Also, remember a successful ending is not the only thing worthy of a celebration. You need to recognize each step of progress you take towards achieving your goals. And no matter how tiny it is, it’s still good news.M: I always feel down when I see others accomplishing things and I feel miserable about my own achievements. I’m always trying to be as good as others, but I never seem to get there.W: Listen. If you always compare yourself with others, you’ll never feel good enough. You’re the on ly person you should be comparing yourself with. When you compare your current status with the starting point, you’ll find you’ve made progress, right? That’s good enough.M: That’s great advice. Thank you.

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 1Single-sex education can have enormous benefits for female students. Numerous studies have shown that women who attend single-sex schools tend to have stronger self-confidence, better study habits and more ambitious career goals than women who attend coeducational schools. Girls who graduate from single-sex schools are three times more likely to become engineers than those who attend coeducational schools. The reason is that all-girls schools encourage women to enter fields traditionally dominated by men such as science, technology and engineering. In coeducational schools, girls are often expected to succeed only in humanities or the art. Research has also shown that in coeducational settings, teachers are more likely to praise and give in-depth responses to boys’ comments in class. In contrast, they might only respond to a girl’s comments with a nod. They are also more likely to encourage boys to work through problems on their own, while they tend to step in and help girls who struggle with a problem.In an all girls setting, girls are more likely to speak up frequently and make significant contributions to class than in acoeducational setting. Girls studying in a single-sex setting also earn higher scores on their College Board and advanced placement exams than girls who study in coeducational settings. All girls schools tend to be smaller than coeducational schools, which means teachers would be able to tailor the materials to girl students’ personal learning styles and interest.Questions 16 to 18 are based on the passage you have just heard.Q16: What advantage does the speaker say girls from single-sex schools have over those from coeducational schools?A) They have a stronger sense of social responsibility.B) They are more likely to succeed in the humanities.C) They are more likely to become engineers.D) They have greater potential to be leaders.Q17: What do teachers tend to do in coeducational settings?A) Praise girls who like to speak up frequently.B) Encourage girls to solve problems on their own.c) Insist that boys and girls work together more.D) Respond more positively to boys’ comments.Q18: What are teachers more likely to do in an all-girls’ school?A) Offer personalized teaching materials.B) Provide a variety of optional courses.C) Place great emphasis on test scores.D) Pay extra attention to top students.Passage 2Today I found out that Seattle doesn’t really get that much rain compared with most US cities. In fact, Seattle ranks 44th among major US cities in average annual rainfall. Cities that get more rainfall than Seattle include Huston, Memphis, Nashville, and pretty much every major city on the eastern coast, such as New York, Boston, and Miami.So, why does everyone think of Seattle as a rainy city? The primary root of this misconception lies in that Seattle has a relatively large number of days per year with rainfall compared with New York and Boston, which get an average of about 16% more rain per year than Seattle, but also average between them about 36 fewer days a year of rainfall. So it rains a lot less in Seattle. And the rain is spread out over more days than those cities. This is why few locals in Seattle carry an umbrella generally. When it does rain, it tends to be a very light rain tha t isn’t troublesome. It almost never really rains as most people think. On top of that, it never really storms in Seattle, either. Seattle gets an average of a mere 7 days a year with thunder.So in short, if you like sunny but not too hot summers, mild winters but with lots of cloudy days, Seattle’s the place to be. Anyway, if you visit Seattle, don’t bring an umbrella. People will look at you, thinking you are funny.Questions 19-21 are based on the passage you have just heard.Q19. What does the speaker find out about Seattle?A) It often rains cats and dogs.B) It seldom rains in summer time.C) It does not rain as much as people think.D) It is one of the most rainy cities in the US.Q20. Why do local people in Seattle seldom carry an umbrella?A) They drive most of the time.B) The rain is usually very light.C) They have got used to the rain.D) The rain comes mostly at night.Q21. Why does the speaker say ‘Seattle is a good place to be’?A) It has a lot of places for entertainment.B) It has never seen thunder and lighting.C) It has fewer cloudy days than any other coastal city.D) It has mild weather both in summer and in winter.Passage 3After tough workout or a day full of physical activity, it’s common to find your muscles aching, but where do these pains come from? According to a German professor, the soreness comes from straining your muscles in an uncommon way, for example, jumping on a bicycle for a ride, because you haven’t ridden in a long time. Soreness occurs since your leg muscles aren't used to that movement. When muscles perform an activity they aren’t regularly expose to, the tiny fibers that are inside them are being torn apart. As muscle soreness develops, the body has to work to repair the muscle tears, but this doesn’t happen immediately. First, the body must realize the muscles are damaged. When the body realizes the muscles are hurt, the response is to increase blood flow to the area and increase body heat, damaged cells are then cleaned up and the body sends cells specially designed to break down the large muscle fiber fragments. Healing can take place after this. It takes about a day until these cells make it to your aching muscles. That’s why there is most often a delay associated with muscle soreness. Repair of damaged cells takes about two days, and afterwards the soreness disappears. Unfortunately, there is little that can be down to relieve muscle soreness. Pain relieving creams don’t work, but a hot shower, or warm bath can provide some relief.Questions 22-25 are based on the passage you have just heard.22. What does the German professor say about muscle soreness?A) It occurs when people are doing a repetitive activity.B) It results from exerting one’s muscles continuously.C) It happens when people engage in an uncommon activity.D) It comes from staining one’s muscles in an unusual way.23.

2019年12月四级真题及答案
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。

Overnight,Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colderthan Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zeroin Park Rapids, Minnesota, and 45 degreesbelow zero in Buffalo, North Dakota,according to the National Weather Service. Schools, restaurants, and businessesclosed, and more than l ,000 flights have been canceled.【[B] Even the United States Postal Service (USPS) suspended mail deliverytemporarily. "Due to this arctic outbreak and concerns for the safety of USPSemployees," USPS announced Wednesday morning, the Postal Service is suspendingdelivery Jan. 30 in the following 3-digit ZIP Code locations." Twelve regions werelisted as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extremeweather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and othernatural disasters cost at least $49 billion in the United States. As my colleague VannNewkirk reported, Puerto Rico is still confronting economic and structural destructionand resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck acommunity'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 dronecaught footage of a USPS worker, Trevor Smith, driving through burned homes in thatfamiliar white van, collecting mail in an affected area. The video is striking: Theoperation is familiar, but the scene looks like the end of the world. According to RaeAnn Haight, the program manager for thenational-preparedness office at USPS,Smith was fulfilling a request made by some of the home owners to pick up any mailthat was left untouched. For Smith, this was just another day on the job. I followedmy route like I normally do," Smith told a reporter. As I'd come across a box thatwas up but with no house, I checked, and there was mail- -outgoing mail- -in it. Andso we picked those up and carried on.'[E] USPS has sophisticated emergency plans for natural disasters. Across thcountry, 285 emergency-management teams are devoted to crisis control. These teamsare trained annually using a framework known as the three Ps: people, property,product. After mail service stops due to weather, the agency 's top priority is ensuringthat employees are safe. Then it evaluates the health of infrastructure, such as theroads that mail carriers drive on. Finally, it decides when and how to re-openoperations. If the destruction is extreme, mail addressed to the area will get sentelsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming NewOrleans mail to existing mail facilities in Houston. Mail that was already processed inNew Orleans facilities was moved to an upper floor so it would be protected fromwater damage.[F] As soon as it's safe enough to be outside,' couriers start distributingaccumulated mail on the still-accessible routes. USPS urges those without standingaddresses to file change-of- address forms with their new location. After HurricaneKatrina hit in 2005, mail facilities were set up in dozens of other locations across thecountry in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, million pieces ofmail -anything from postcards to Social Security checks to medicine. Spokespeoplefrom both USPS and UPS told me all mail is important. But some mail can beextremely sensitive and timely. According to data released in January 2017, 56percent of bills are paid online, which means that just under half of payments still relyon delivery services to be completed.[H]It can be hard to identify which parcels are carrying crucial items such asSocial Security checks, but USPS and UPS try their best to prioritize sensitivematerial. They will coordinate with the Social Security Administration to make surethat Social Security checks reach the right people in a timely fashion. After HurricaneFlorence and Hurricane Michael last fall, USPS worked with state and local electionboards to make sure that absentee ballots were available and received on time.^[I] Mail companies are logistics companies, which puts them in a special positionto help when disaster strikes. In a 2011 USPS case study, the agency emphasized itsmassive infrastructure as a unique federal asset" to be called upon in a disaster orterrorist attack. I think we're unique as a federal agency," USPS official MikeSwigart told me, because we're in literally every community in this countryWe' re obligated to deliver to that point on a daily basis.'[J]Private courier companies, which have more dollars to spend, use theirexpertise in logistics to help revitalize damaged areas after a disaster. For more than adecade, FedEx has supported the American Red Cross in its effort to get emergencysupplies to areas affected by disasters, both domestically and internationally. In 2012,the company distributed more than 1,200 MedPacks to Medical Reserve Corps groupsin California, and donated space for million pounds of charitable shipping October, the company pledged $1 million in cash and transportation support forHurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, usesthe company 's logistics to help disaster-struck areas rebuild. We realize that as acompany with people, trucks, warehouses, we needed to play a larger role," saidEduardo Martinez, the president of the UPS Foundation. The company employs it:trucks and planes to deliver food, medicine, and water. The day before I spoke toMartinez in November, he had been touring the damage from Hurricane Michael inFlorida with the American Red Cross. Wehave an obligation to make sure ourcommunities are thriving, prosperous," he said.[K] Rebuilding can take a long time, and even then, impressions of the disastermay still remain. Returning to a sense of normalcy can be difficult, but some smallroutines- -mail delivery being one of them- -may help residents remember that theircommunities are still their communities. When they see that carrier back out on thestreet," Swigart said, that's the first sign to them that life is starting to return tonormal."36. The United States Postal Service has a system to ensure its employees' safety.37. One official says USPS is unique in that it has more direct reach tccommunities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half ofpayments.！40. The sight of a mailman on the street is a reassuring sign of life becomingnormal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail servicepoints were set up.42. Postal service in some regions in the . was suspended due to extreme coldweather.43. Private postal companies also support disaster relief efforts by distributingurgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite ofextreme conditions.45. Postal services work hard to identify items that require priority treatment.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 fourchoices marked A), B), C) and D). You should decide on the best choiceand 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.Professor Ashok Goel of Georgia Tech developed an artificially intelligentteaching assistant to help handle the enormous number of student questions in theonline class, Knowledge Based Artificial Intelligence. This online course is a corerequirement of Georgia Tech's online Master of Science in Computer Scienceprogram. Professor Goelalready had 8 teaching assistants, but that wasn t enough todeal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching students feel isolated or confused and reach out with questions that gounanswered, their motivation to continue begins to fade. Professor Goel decided to dosomething to remedy this situation and his solution was to create a virtual assistantnamed Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill W atson before releasing herto the online forums. At first, the virtual assistant wasnt too great. But Goel and histeam sourced the online discussion forum to find all 40,000 questions that had everbeen asked since the class was launched. Then they began to feed Jill the questionsand answers. After some adjustment and sufficient time, Jill was able to answer thestudents questions correctly 97% of the time. The L virtual assistant became soadvanced and realistic that the students didn t know she was a computer. The students,who were studying artificial intelligence, were interacting with artificial intelligenceand couldn't tell it apart from a real human being. Goel didn 't inform them about Jill'strue identity until April 26. The students were actually very positive about theexperience.The goal of Professor Goel's virtual assistant next year is to take over answering40% of all questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a muchrosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence】A) It is a robot that can answer students' questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet withA) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students questions were too many to handle.】D) Too many students dropped out of his course.48. What do we learn about Jill WatsonA) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.10/23149. How did the students feel about Jill W atson）A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill W atsonA) Launch different versions of her online.B) Feed her with new questions and answers.c) Assign her to answer more of students questions.&D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don' t hurt. 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.

Imagine you are wandering about on a Thai island or 26 the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It’s the safe, sane thing to do, right? 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. These studies showed that their water did contain microplastics, but far less than the Orb study suggested. Regardless, the World Health Organization has now launched a review into the 35 health risks of drinking water from plastic bottles.Section BDirections: In this section, you are going to read a passage with ten statements attached to each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The 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. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague V ann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017’s Hurrican e Maria. 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. Thevideo is striking: The operation is familiar, but the scene looks like the end of the world. 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. And so we picked those up and carried on.”[E] USPS has sophisticated emergency plans for natural disasters. Across the country, 285 emergency-management teams are devoted to crisis control. These teams are trained annually using a framework known as the three Ps: people, property, product. After mail service stops due to weather, the agen cy’s top priority is ensuring that employees are safe. Then it evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations. If the destruction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be protected from water damage.[F] As soon as it’s safe enough to be outside, couriers start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change-of-address forms with their new location. After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of other locations across the country in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces of mail—anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed. [H] It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the agency emphasized its massive in frastructure as a “unique federal asset” to be called upon in a disaster or terrorist attack. “I think we’re unique as a federal agency,” USPS official MikeSwigart told me, “because we’re in literally every community in this country … We’re obligated to d eliver to that point on a daily basis.”[J] Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California, and donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebu ild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving, prosperous,” he said.[K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half of payments.40. The sight of a mailman on the street is a reassuring sign of life becoming normal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up.42. Postal service in some regions in the U.S. was suspended due to extreme cold weather.43. Private postal companies also support disaster relief efforts by distributing urgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions.45. Postal services work hard to identify items that require priority treatment.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.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor G oel already had 8 teaching assistants, but that wasn’t enough to deal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with artificial intelligence and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all questions posed by students on the online forum. The name, Jill Watson, will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students’ questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students’ questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success. B) She got along pretty well with students.C) She was unwelcome to students at first. D) She was released online as an experiment.49. How did the students feel about Jill Watson?A) They thought she was a bit too artificial. B) They found her not as capable as expected.C) They could not but admire her knowledge. D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill Watson?A) Launch different versions of her online.B) Feed her with new questions and answers.C) Assign her to answer more of students’ questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being enga ging, and having a sense of humor don’t hurt. 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.

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. So when I can't do this, I take guys out to dinner one-to-one-to places where I'm most likely to see colleagues. [28]The more your colleagues see you having working dinners with different men, the more they know it is part of your business style.
