If you are on a plane with a sick passenger, you are unlikely to get sick. 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 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. litter 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 US. 34 side of a person infected with flu, as well as those sitting one roe in font of or behind this individual, had about an 80 person 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）accurate B）conclusion C）directlyD）either E）evaluate F）explorationsG）flights H）largely I）nearbyJ）respond K）slim L）spreadM）summit N）vividly O）vulnerable【参考答案】26-30 BLKAO31-35 CEGDHSection BA South Korean city designed for the future takes on a life ofits ownA）Getting around a city is one thing —and then there’s the matter of getting from one city to another. 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 hehas pu t it, is to offer 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 conne cted 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 o n the basis of connectivity and competitiveness,”says Kasada. “The gov ernment 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 con siders 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 livingin the business district and 90,000 residents in greater Songdo. It’s about an hour outside Se oul, 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 actu ally seen this place. Songdo appears in the most famous music video ev er to come ou of South Korea. “Gangnam Style” refers tothe 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 Song do,” 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 wor ld. 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 th e 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 p opular 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 happe ned 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 unfinished, 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 o f 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 outthere, too. The world is dotted with futuristic, high-tech cities trying to attract the biggest international companies J）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 utopian （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.36. Son gdo’s popularity lies more in its quality of life than its business attraction.37. The man who conceives Songdo feels disappointed because it has fallen short of his expectations.38. A scene in a popular South Korean music video was shot in Songdo.39. Songdo still lacks the financial stimulus for businesses to set up shop there.40. Airplanes will increasingly become the chief means of transportation, according to a professor.41. Songdo has ended up different from the city it was supposed to be.42. Some of the people who work in Songdo complain about boredom in the workplace.43. A business professor says that a future city should have easy access to international transportation.44. Acording to an urban design professor, it is difficult for city designers to foresee what happen in the future.45. Park Yeon So. Who envisioned Songdo, feels a parental connection with the city.【参考答案】36-40 FIDGB41-45 EHAJCSection CPassage 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）1.5cents 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 bev erage s—including low- and no-calorie choices,” said Lauren Kane, spokeswoman 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 l asting 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 wi ll sure be inspirational to many other places,” said Jim Krieger, executive director of Healthy Food America. “Indeed, we are already hearing 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.46. 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.47. 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.48. What did the industry-backed anti-tax campaign doabout 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.49. 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.50. 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.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 end of the decade.A study by the University of Manchester calculated the emissions of CO2—the main greenhouse gas responsible forclimate change—at every stage of microwaves, from manufacture to waste di sposal. “It is electricity consumption by micr owaves that has the biggest impact on the environment,” say the authors. The authors also calculate that the emissions from using 19 microwaves over a year are the same as those from using a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour. For example, consumers could use appliances in a more efficient way by adjusting the time of cooking to the type of food.However, David Reay, professor of carbon management, argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone, there are around 30 million cars. These cars emit more than all the microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69 million tons of CO2 in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the EU. Further, the energy used by microwaves is lower than any other from of cooking. Among common kitchen appliances used for cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.51. What is the finding of the new study?A）Quick-cooking microwave ovens have become more popular.B）The frequent use of microwaves may do harm to our health.C）CO2 emissions constitute a major threat to the environment.D）The use of microwaves emits more CO2 than people think.52. Why are the sales of microwaves expected to rise?A）They are becoming more affordable.B）They have a shorter life cycle than other appliances.C）They are getting much easier to operate.D）They take less time to cook than other appliances.53. What recommendation does the study by the University of Manchester make? A）Cooking food of different varieties.B）Improving microwave users’ habits.C）Eating less to cut energy consumption.D）Using microwave ovens less frequently.54. What does Professor David Reay try to argue?A）There are far more emissions from cars than from microwaves.B）People should be persuaded into using passenger cars less often.C）The UK produces less CO2 than many other countries in the EU.D）More data are needed to show whether microwaves are harmful.55. What does Professor David Reay think of the use of microwaves?。

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.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 to another. 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 offer 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 increasi ngly 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 ofthe 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 seen this place. Songdo appears in the most famous musi c 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 act ually 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 ov er 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 mi ddle 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 Korean city 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 happened 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 unfinished, 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 wee kend. “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 utopian （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.36. Songdo’s popularity lies more in its quality of life than its business attraction.37. The man who conceives Songdo feels disappointed because it has fallen short of his expectations.38. A scene in a popular South Korean music video was shot in Songdo.39. Songdo still lacks the financial stimulus for businesses to set up shop there.40. Airplanes will increasingly become the chief means of transportation, according to a professor.41. Songdo has ended up different from the city it was supposed to be.42. Some of the people who work in Songdo complain about boredom in the workplace.43. A business professor says that a future city should have easy access to international transportation.44. Acording to an urban design professor, it is difficult for city designers to foresee what happen in the future.45. Park Yeon So. Who envisioned Songdo, feels a parental connection with the city.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 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.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 approve d 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 ta x passed today unfairly singles out beverages—including low- and no-calorie choices,” said Lauren Kane, spokeswoman 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 already hearing 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.46. 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.47. 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.48. 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.49. 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.50. 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.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. Withcosts 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 end of the decade.A study by the University of Manchester calculated the emissions of CO2—the main greenhouse gas responsible for climate change—at every stage of microwaves, from manufacture to wast e disposal. “It is electricity consumption by microwaves that has the biggest impact on the environment,” say the authors. The authors also calculate that the emissions from using 19 microwaves over a year are the same as those from using a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour. For example, consumers could use appliances in a more efficient way by adjusting the time of cooking to the type of food.However, David Reay, professor of carbon management, argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone, there are around 30 million cars. These cars emit more than all the microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69 million tons of CO2 in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the EU. Further, the energy used by microwaves is lower than any other from of cooking. Among common kitchen appliances usedfor cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.51. What is the finding of the new study?A） Quick-cooking microwave ovens have become more popular.B） The frequent use of microwaves may do harm to our health.C） CO2 emissions constitute a major threat to the environment.D） The use of microwaves emits more CO2 than people think.52. Why are the sales of microwaves expected to rise?A） They are becoming more affordable.B） They have a shorter life cycle than other appliances.C） They are getting much easier to operate.D） They take less time to cook than other appliances.53. What recommendation does the study by the University of Manchester make?A） Cooking food of different varieties.B）Improving microwave users’ habits.C） Eating less to cut energy consumption.D） Using microwave ovens less frequently.54. What does Professor David Reay try to argue?A） There are far more emissions from cars than from microwaves. B） People should be persuaded into using passenger cars less often. C） The UK produces less CO2 than many other countries in the EU. D） More data are needed to show whether microwaves are harmful.55. What does Professor David Reay think of the use of microwaves? A） It will become less popular in the coming decades.B） It makes everyday cooking much more convenient.C） It plays a positive role in environmental protection.D） It consumes more power than conventional cooking.Part Ⅳ Translation （30 minutes）Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese 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 thing to do, right? The bottle is 27, and the label says "pure water". But maybe what's inside is not so 28. Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29microplastics?That's the conclusion of a recently 30study, which analysed 259 bottles from 11 brands sold in nine countries, 31an average of 325 plastic particles per litre of water. These microplastics included a 32 commonly known as PET and widely used in the manufacture of clothing and food and 33containers. The study was conducted at the State New York on behalf of Orb Media, a journalism organisation. 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 Coca-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 Organisation has launched a review into the 35health risks of drinking water from plastic bottles.A.adequateB.admiringC.containsD.defendingE.evidenceF.instantG.liquidH.modifiedI.natural J.potential K.released L.revealingf e n b i.co mf e nb i.co mf e n b i.co mf e nb i.co mf e n b i.co mf e nb i.co mThe 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(南极洲), 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 were canceled.[B] Even the United States Postal Service(USPS) suspended mail delivery. "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 some 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 Vann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017's Hurricane 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 (无人机) caught footage(连续镜头) of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. The video 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 came 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 agency'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(邮递员) 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 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 andM.sealed N.solves O.substanceHurricane 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 (物流)companies, which puts them in a special position to help when disasterstrikes. In a 2011 USPS case study, the agency emphasized its massive infrastructure 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 Mike Swigart told me,“ because we're in literally every community in this country.. We're obligated to deliver 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. They also donated space for3.1 million pounds of charitable shipping globally. Last October the company pledged $1 million in cash andtransportation support for Hurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, uses the company's logistics to help disaster-struck areas rebuild. "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,"he said.[K]Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a normal life can be difficult, but some small routines—mail delivery being one of them—may help residentsremember 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 federalagencies.38.Natural disasters can have a long-lasting impact on community life.39.Mail delivery service is 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.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. Professorf e n b i .c o m f e n b i .c o m Goel already had eight teaching assistants, but that wasn't enough to deal with the overwhelming number of daily 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 the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advance and realistic that the students didn't know she was a computer. The students who were studying artificial intelligence, were interacting with the virtual assistant 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 the 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 artificial intelligence than, say Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46.What do we learn about Knowledge-Based Artificial Intelligence?47.What problem did Professor Goel meet with?48.What do we learn about Jill Watson?49.How did the students feel about Jill Watson?50.What does Professor Goel plan to do next with Jill Watson?unch 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.Thinking small, being engaging, and having a sense of humor don't hurt. Those are a few of the traits ofsuccessful 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 producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goals, but others have fallen short of reaching even modest targets.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.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.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.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.f e n b i .c o m f e n b i .c o m f e n b i .c o m f e nb i .c o m To determine what separates science crowdfunding triumphs from failures, a team led by sciencecommunications scholar Mike Schafer of the University of Zurich examined the content of the webpages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in PublicUnderstanding 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 fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% 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 success, most notably, the size of a scientist's personal and professional networks, and how much a researcher promotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers' efforts to reach the public, and people give because"they feeI 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?52.What is the purpose of Mike Schafer's research of recent crowdfunding campaigns?53.What trait contributes to the success of a crowdfunding campaign?54.What did the researchers think of the financial targets of crowdfunding projects?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 IV Translation (30 minutes)For this part, you are allowed 30 minutes to translate a passage from Chinese into English.中国的家庭观念与其文化传统有关，和睦的大家庭曾非常令人羡慕。

"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 some 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 Vann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017's Hurricane 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 (无人机) caught footage(连续镜头) of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. The video 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 came 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 agency'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(邮递员) 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 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 andM.sealed N.solves O.substanceHurricane 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 (物流)companies, which puts them in a special position to help when disasterstrikes. In a 2011 USPS case study, the agency emphasized its massive infrastructure 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 Mike Swigart told me,“ because we're in literally every community in this country.. We're obligated to deliver 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. They also donated space for3.1 million pounds of charitable shipping globally. Last October the company pledged $1 million in cash andtransportation support for Hurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, uses the company's logistics to help disaster-struck areas rebuild. "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,"he said.[K]Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a normal life can be difficult, but some small routines—mail delivery being one of them—may help residentsremember 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 federalagencies.38.Natural disasters can have a long-lasting impact on community life.39.Mail delivery service is 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.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. Professorf e n b i .c o m f e n b i .c o m Goel already had eight teaching assistants, but that wasn't enough to deal with the overwhelming number of daily 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 the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advance and realistic that the students didn't know she was a computer. The students who were studying artificial intelligence, were interacting with the virtual assistant 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 the 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 artificial intelligence than, say Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46.What do we learn about Knowledge-Based Artificial Intelligence?47.What problem did Professor Goel meet with?48.What do we learn about Jill Watson?49.How did the students feel about Jill Watson?50.What does Professor Goel plan to do next with Jill Watson?unch 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.Thinking small, being engaging, and having a sense of humor don't hurt. Those are a few of the traits ofsuccessful 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 producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goals, but others have fallen short of reaching even modest targets.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.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.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.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.f e n b i .c o m f e n b i .c o m f e n b i .c o m f e nb i .c o m To determine what separates science crowdfunding triumphs from failures, a team led by sciencecommunications scholar Mike Schafer of the University of Zurich examined the content of the webpages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in PublicUnderstanding 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 fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% 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 success, most notably, the size of a scientist's personal and professional networks, and how much a researcher promotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers' efforts to reach the public, and people give because"they feeI 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?52.What is the purpose of Mike Schafer's research of recent crowdfunding campaigns?53.What trait contributes to the success of a crowdfunding campaign?54.What did the researchers think of the financial targets of crowdfunding projects?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 IV Translation (30 minutes)For this part, you are allowed 30 minutes to translate a passage from Chinese into English.中国的家庭观念与其文化传统有关，和睦的大家庭曾非常令人羡慕。

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。

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.

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 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.

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.

英语四级听力50篇：45 The Influence of Life
In the early times when human beings hunted and gathered food, they were not in control of their environment. They could only interact with their surroundings as the other lower animals did.
When they learned to make fire, however, they became capable of altering their environment. To provide themselves with fuel, they cut down trees. They also burned clearings in forests to increase the growth of grass and to provide a greater grazing area for the wild animals that human beings fed upon. This development led to famp3ing and the domestication of animals. Fire provided the means for cooking plants which had previously been inedible. Only when the process of meeting the basic need for food reached a certain level was it possible for humans to follow other pursuits such as setting up families, fomp3ing societies and founding cities.
Useful words and Expressions：
1. interact with 与……组合
2. clearing 空旷地
3. grazing 放牧，牧草
4. domestication 驯养，驯服
5. previously 先前，以前
6. inedible 不能吃的，不适于食用的
