美国数学建模题目2017至2017翻译篇一：2017年建模美赛C题带翻译Problem C: “Cooperate and navigate”Traffic capacity is limited in many regions of the United States due to the number of lanes of roads.For example, in the Greater Seattle area drivers experience long delays during peak traffic hoursbecause the volume of traffic exceeds the designed capacity of the road networks. This is particularlypronounced on Interstates 5, 90, and 405, as well as State Route 520, the roads of particular interestfor this problem.Self-driving, cooperating cars have been proposed as a solution to increase capacity of highwayswithout increasing number of lanes or roads. The behavior of these cars interacting with the existingtraffic flow and each other is not well understood at this point.The Governor of the state of Washington has asked for analysis of the effects of allowing self-driving,cooperating cars on the roads listed above in Thurston, Pierce, King, and Snohomish counties. (Seethe provided map and Excel spreadsheet).In particular, how do the effects change as thepercentage of self-driving cars increases from 10% to 50% to 90%? Do equilibria exist? Is there atipping point where performance changes markedly? Under what conditions, if any, should lanes bededicated to these cars? Does your analysis of your model suggest any other policy changes?Your answer should include a model of the effects on traffic flow of the number of lanes, peak and/oraverage traffic volume, and percentage of vehicles using self-driving, cooperating systems. Yourmodel should address cooperation between self-driving cars as well as the interaction between self-driving and non-self-driving vehicles. Your model should then be applied to the data for the roads ofinterest, provided in the attached Excel spreadsheet.Your MCM submission should consist of a 1 page Summary Sheet, a 1-2 page letter to theGovernor’s office, and your solution (not to exceed 20 pages) for a maximum of 23 pages. Note: Theappendix and references do not count toward the 23 page limit. Some useful background information:On average, 8% of the daily traffic volume occurs during peak travel hours. ? The nominal speed limit for all these roads is 60 miles per hour.? Mileposts are numbered from south to north, and west to east.? Lane widths are the standard 12 feet.? Highway 90 is classified as a state route until it intersects Interstate 5.? In case of any conflict between the data provided in this problem and any other source, use thedata provided in this problem.Definitions:milepost: A marker on the road that measures distance in miles from either the start of the route or astate boundary.average daily traffic: The average number of cars per day driving on the road.interstate: A limited access highway, part of a national system.state route: A state highway that may or may not be limited access.route ID: The number of the highway.increasing direction: Northbound for N-S roads, Eastbound for E-W roads.decreasing direction: Southbound for N-S roads, Westbound for E-W roads.问题C：“合作和导航”由于道路的数量，美国许多地区的交通容量有限。

2017年5月CATTI英语二级笔译真题一、英译汉第一篇：出自The 2030 Agenda For Sustainable DevelopmentThis Agenda is a plan of action for people, planet and prosperity. It also seeks to strengthen universal peace in larger freedom. We recognize that eradicating poverty in all its forms and dimensions, including extreme poverty, is the greatest global challenge and an indispensable requirement for sustainable development.We are resolved to free the human race from the alleviation of poverty and heal and protect our planet.We are determined to take the bold and transformative steps which are urgently needed to shift the world onto a sustainable and resilient path.The 17Sustainable Development Goals and 169 targets which we are announcing today demonstrate the scale and ambition of this new universal Agenda. They seek to build on the Millennium Development Goals and complete what these did not achieve. They seek to realize the human rights of all and to achieve gender equality and the empowerment of all women and girls. They are integrated and indivisible and balance the three dimensions of sustainable development: the economic, social and environmental.We are meeting at a time of immense challenges to sustainable development.Billions of our citizens continue to live in poverty and are denied a life of dignity.There are rising inequalities within and among countries. Gender inequality remains a key challenge. Unemployment, particularly youth unemployment, is a major concern. Global health threats, more frequent and intense natural disasters, spiraling conflict, violent extremism, terrorism and related humanitarian crises and forced displacement of people threaten to reverse much of the development progress made in recent decades.Natural resource depletion and adverse impacts of environmental degradation, including desertification, drought, land degradation,freshwater scarcity and loss of biodiversity, add to and exacerbate the list of challenges which humanity faces.Climate change is one of the greatest challenges of our time and its adverse impacts undermine the ability of all countries to achieve sustainable development.The Millennium Development Goals were agreed 15 years ago provided an important framework for development and significant progress has been made in a number of areas. But the progress has been uneven, particularly in Africa, least developed countries, landlocked developing countries, and small island developing States, and some of the Millennium Development Goalsremain off-track,in particular those related to maternal, newborn and child health and to reproductive health. We recommit ourselves to the full realization of all the Millennium Development Goals, including the off-track Millennium Development Goals, in particular by providing focused and scaled-up assistance to least developed countries and other countries in special situations, in line with relevant support programs. The new Agenda builds on the Millennium Development Goals and seeks to complete what these did not achieve, particularly in reaching the most vulnerable countries.二、英译汉第二篇：出自2010年EconomistEntrepreneurs in Silicon Valley, only half-jokingly, call it the URL strategy.The three letters usually stand for Uniform Resource Locator—the unique address of any file that is accessible via the internet. But in the world of internet start-ups, URL has another meaning: Ubiquity first, Revenue Later. This pretty much describes the strategy of most big online social networks, which over the past few years have concentrated on piling on users rather than worrying aboutprofits.That has allowed them to build huge followings, but it has also raised a big question-mark over their ability to make money from the audiences they have put together.At issue is whether the social-networking industry can come up with a wildly successful form of advertising in the same way that Google has been able to make billions of dollars from the targeted ads that run alongside the search results it serves up. Without such a formula,runs the argument, social networks such as Facebook will never amount to much.Doubters claim that the networks face two big handicaps. The first is that people logged into social-networking sites are there to hang out with their friends, so they will pay no attention to ads. The second is that because the sites let users generate their own content, they will find it hard to attract advertisers because brands will not want to take the risk of appearing alongside examples of profanity,obscenity or nudity—or all three at once.But the broader outlook for networking sites is more encouraging. One reason is that advertisers are being drawn to the leading sites by their sheer scale. Facebook's audience is bigger than any TV network that has ever existed on the face of the earth. Another thing that has attracted companies is the networks' ability to target ads with laser-like precision, thanks to the data they hold on their users' ages, gender, interests and so forth. Although there are still lingering concerns about brands appearing next to racy content, firms seem more willing to run this risk now that the networks' advertising proposition has become more compelling.In addition to advertising-driven business model, networks are already making healthy profits from sales of games and virtual goods. The beauty of this business for social networks is that the cost of producing and storing virtual inventory is minimal. Moreover, because these are closed markets, networks can fix prices at levels that generate fat margins. To some, the notion that big money can be made from selling make-believe items may seem bizarre. But the practice replicates the physical presents that people give to one another to cement relationships in the real world.三、汉译英第一篇：出自中国五矿集团公司介绍本公司是全球最大最强的冶金建设运营服务商，拥有24万在职员工，资产规模超7000亿元，境外机构、资源项目与承建工程遍布全球60多个国家和地区。

2017年考研英语二翻译试题答案及解析

2017年考研英语二翻译试题答案及解析My DreamMy dream has always been to work somewhere in an area between fashion and publishing. Two years before graduating from secondary school, I took a sewing and design course thinking that I would move on to a fashion design course. However, during that course I realised that I was not good enough in this area to compete with other creative personalities in the future, so I decided that it was not the right path for me. Before applying for university I told everyone that I would study journalism, because writing was, and still is, one of my favourite activities. But, to be absolutely honest, I said it, because I thought that fashion and me together was just a dream - I knew that no one, apart from myself, could imagine me in the fashion industry at all!2017年英语二的翻译题是一篇关于梦想的小短文，全文共5句话，前两句话比较简短且简单，后三句较长，但难度也都不大。

In just a few hours, she was due to depart on her first trip to Africa. A school friend had moved to a farm outside Nairobi and, knowing Goodall ' s childhood dream was to live among the African wildlife, invited her to stay with the family for a while. Goodall, then 22, saved for two years to pay for her passage toKe nya: waitress ing, doing secretarial work, temp ing at the post office in her hometown, Bournemouth, on England ' southern coast. Now all this was for n aught, it seemed.It ' s hard not to wonder how subsequent events in her liferather conseque—ial as they have turned out to be to con servati on, to scie nee, to our sense of ourselves as a species—might have un folded differe ntly had some one not found her passport, along with an it in erary from Cook ' s, the travel age ncy, folded in side, and delivered it to theCook' s office. An agency representative, documents in hand, found her on the dock.“In credible, ” Goodall told me last mon th, recalli ng that day. “ Amazi ng.With in two mon ths of her arrival, Goodall met the pale on tologist Louis Leakey——Nairobi was a small town for its white population in those days ——and he immediately offered her a job at the n atural-history museum where he was curator. He spe nt much of the n ext three years test ing her capacity for repetitive work.He believed in a hypothesis first put forth by Charles Darwin that humans and chimpa nzees share an evoluti onary an cestor. Close study of chimpa nzees in the wild, he thought, might tell us someth ing about that com mon proge nitor. He was, in other words, look ing for some one to live among Africa ' s wild an imals. One ni ght, he told Goodall that he knew just the place where she could do it: Gombe Stream Chimpa nzee Reserve, in the British colony of Tangany ika (now Tanzani a).In July 1960, Goodall boarded a boat and after a few hours motoring over thewarm, deep waters of Lake Tangany ika, she stepped onto the pebbly beach at Gombe.Her finding, published in Nature in 1964, that chimpanzees use tools —extract ing in sects from atermite mound with leaves of grass —drastically and forever altered huma nity ' understa nding of itself; man was no Ion ger the n atural world ' s only user of tools.After two and a half decades of liv ing out her childhood dream, Goodall made an abrupt career shift, from scie ntist to con servati oni st.Passage 2Scien tists have found the first evide nee that briny water flowed on the surface of Mars as rece ntly as last summer, a paper published on Mon day showed, rais ing the possibility that the pla net could support life.Although the source and the chemistry of the water is unknown, the discovery will cha nge scie ntists ' thinking about whether the pla net that is most like Earth in the solar system could support prese nt day microbial life.The discovery was made whe n scie ntists developed a new tech nique to an alyze chemical maps of the surface of Mars obtained by NASA s Mars Reconnaissanee Orbiter spacecraft.They found telltale fingerprints of salts that form only in the presence of water in narrow channels cut into cliff walls throughout the planet region. s equatorial The slopes appear duri ng the warm summer mon ths on Mars, the n vanish whe n the temperatures drop.

That data was the n correlated with high-resolutio n images of the streaks.

PROBLEM A:Managing The Zambezi RiverThe Kariba Dam on the Zambezi River is one of the larger dams in Africa.Its construction was controversial,and a2015report by the Institute of Risk Management of South Africa included a warning that the dam is in dire need of maintenance.A number of options are available to the Zambezi River Authority(ZRA)that might address the situation.Three options in particular are of interest to ZRA:(Option1)Repairing the existing Kariba Dam,(Option2)Rebuilding the existing Kariba Dam,or(Option3)Removing the Kariba Dam and replacing it with a series of ten to twenty smaller dams along the Zambezi River.There are two main requirements for this problem:Requirement1ZRA management requires a brief assessment of the three options listed, with sufficient detail to provide an overview of potential costs and benefits associated with each option.This requirement should not exceed two pages in length,and must be provided in addition to your main report.Requirement2Provide a detailed analysis of Option(3)-removing the Kariba Dam and replacing it with a series of ten to twenty smaller dams along the Zambezi river.This new system of dams should have the same overall water management capabilities as the existing Kariba Dam while providing the same or greater levels of protection and water management options for Lake Kariba that are in place with the existing dam.Your analysis must support a recommendation as to the number and placement of the new dams along the Zambezi River.In your report for Requirement2,you should include a strategy for modulating the water flow through your new multiple dam system that provides a reasonable balance between safety and costs.In addition to addressing known or predicted normal water cycles,your strategy should provide guidance to the ZRA managers that explains and justifies the actions that should be taken to properly handle emergency water flow situations(i.e. flooding and/or prolonged low water conditions).Your strategy should provide specific guidance for extreme water flows ranging from maximum expected discharges to minimum expected discharges.Finally,your recommended strategy should include information addressing any restrictions regarding the locations and lengths of time that different areas of the Zambezi River should be exposed to the most detrimental effects of the extreme conditions.Your MCM submission should consist of three elements:a standard1page MCM Summary Sheet,a1-2page brief assessment report(Requirement1),and your main MCM solution (Requirement2)not to exceed20pages for a maximum submission of23pages.Note: Any appendices or reference pages you include will not count towards the23page limit.A题中文翻译：问题A：管理赞比西河赞比西河上的卡里巴水坝是非洲较大的水坝之一。

每头牛的名字有一个“独特因数”，这个独特因数指的是区别于其他牛的名字的子字符串的数目。

举个例子，只是amy，那么她的独特因数就是6。

如果是只是Tommy的话，他是独特因数将是14。

如果他们作为一个群体，amy的独特因数只有3，Tommy的只有11。

给定一群奶牛，请确定每头牛的独特因数。

Airline OverbookingYou're all packed and ready to go on a trip to visit your best friend in New York City. After you check in at the ticket counter, the airline clerk announces that your flight has been overbooked. Passengers need to check in immediately to determine if they still have a seat.Historically, airlines know that only a certain percentage of passengers who have made reservations on a particular flight will actually take that flight. Consequently, most airlines overbook-that is, they take more reservations than the capacity of the aircraft. Occasionally, more passengers will want to take a flight than the capacity of the plane leading to one or more passengers being bumped and thus unable to take the flight for which they had reservations.Airlines deal with bumped passengers in various ways. Some are given nothing, some are booked on later flights on other airlines, and some are given some kind of cash or airline ticket incentive.Consider the overbooking issue in light of the current situation:●Less flights by airlines from point A to point B.●Heightened security at and around airports.●Passengers' fear.●Loss of billions of dollars in revenue by airlines to date.Build a mathematical model that examines the effects that different overbooking schemes have on the revenue received by an airline company in order to find an optimal overbooking strategy, i.e., the number of people by which an airline should overbook a particular flight so that the company's revenue is maximized.Insure that your model reflects the issues above, and consider alternatives for handling “bumped” passengers. Additionally, write a short memorandum to the airline's CEO summarizing your findings and analysis.。

"You must see Boston, visit Niagara Falls, go to Virginia, fly down to Florida, and so on; but first, of course, you will want to see New York. It is not the capital city of the United States(that is Washington, D.C. , where the President lives) or even the capital city of New York State(that is Albany), but many people call it 'the greatest city on earth'."The five parts, or boroughs, of New York City are Manhattan, Queen, Bronz, Richmond and Brooklyn. Although Manhattan is not all of New York, it is the heart of the city. It is an island, which is only about 13 miles long and 2 miles wide. From the air its shape looks like a long finger, and from the sea it's just like the picture we all know. Those tall, straight buildings--the skyscrap- ers-packed so close together on that island of rocks are sometimes seen in the distance through a veil of early morning mist. You have imagined it so often that now it's difficult to believe this beautiful sight is real, and unless your heart is as hard as a stone, excitement will lake it beat a lit- tle faster.Perhaps "greatest", "tallest", "longest", "biggest", "brightest", are words you will find most often in the city guide books.1.How many places in America are mentioned in this passage besides New York City?A.6.B.4.C.7.D.5.2. Which of the following statements is NOT TRUE?A. Manhattan is the centre of New York City.B. New York City is made up of five parts.C. New York looks like a long finger from the air.D.
