中国石油化工集团公司2007年工程系列高级任职资格外语考试试卷英语(炼化工程)(120分钟内完成)一、阅读理解(阅读短文,简要回答问题,共25分)短文1(12.5分)Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. Banks may agree to provide short-term finance, they are generally unwilling to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits, this they do by issuing stocks and shares in the business through The Stock Exchange. By doing so they can put into circulation the savings of individuals and institutions, both at home and overseas.When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seeking to invest his money.Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, local authorities, and nationalized industries therefore frequently needed to borrow money to finance major capital spending, and they, too, come to The Stock Exchange.1. What must almost all companies involved in new production and development depend on according to the passage?2. How is the money which enables these companies to go ahead with their projects raised?3. What do the savers do when they want their money back?4. In what conditions are all the essential services on which we depend?5. Why do companies invite people to lend money to them or take a share in the business?短文2(12.5分)Like street–corner prophets proclaiming that the end is near, scientists who study the earth’s atmosphere have been issuing predictions of impending doom for the past few years without offering any concrete proof. So far even the experts have had to admit that no solid evidence has emerged that this is anything but a natural phenomenon. And the uncertainty has given skeptics—especially Gingrichian politicians—plenty of ammunition to argue against taking the difficult, expensive steps required to stave off a largely hypothetical calamity.Until now, a draft report currently circulating on the Internet asserts that the global-temperature rise can now be blamed, at least in part, on human activity. Statements like this have been made before by individual researchers—who have been criticized for going too far beyond the scientific consensus. But this report comes from the International Panel on Climate Change(IPCC), a respected UN-sponsored body made up of more than 1,500 leading climate experts from 60 nations.This shift in scientific consensus is based not so much on new data as on improvements in the complex computer models that climatologists use to test their theories. Unlike chemists or molecular biologists, climate experts have no way to do lab experiments on their specialty. So they simulate them on supercomputers and look at what happens when human-generated gases —carbon dioxide from industry and auto exhaust, methane from agriculture, chlorofluoro-carbon from leaky refrigerators and spray cans—are pumped into the model’s virtual atmospheres.Until recently, the computer models weren’t working very well. When the scientists tried to simulate what they believe has been happening over the past century or so, the results didn’t mesh with reality; the models said the worldshould now be warmer than it actually is. The reason is that the computer models had been overlooking an important factor affecting global temperatures; sulfur dioxide that are produced along with CO2 when fossil fuels are burned in cars and power plants. Aerosols actually cool the planet by blocking sunlight and mask the effects of global warming.Once the scientist factored in aerosols, their models began looking more like the real world. The improved performance of the simulations was demonstrated in 1991, when they successfully predicted temperature changes in the aftermath of the massive Mount Pinatubo eruption in the Philippines. A number of studies since have added to the scientists’confidence that they finally know what they’re talking about—and can predict what may happen if green house gases continue to be pumped into the atmosphere unchecked.1. Why can’t scientists and experts offer any concrete proof of impending doom?2. What does a current draft report on the Internet confirm?3. How do climate experts do lab experiments on their specialty?4. What important factor mentioned in paragraph four can also affects global temperatures?5. The simulated computer models are proved reliable when__________.二、英译汉(将下列短文译成汉语,共45分)短文1(20分,A、B两篇,只翻译一篇,任选其一)A How do scientists separate the hydrocarbons? They distil the oil. They turn the oil into vapor and then turn the vapor into liquids.The theory of distillation is very easy. Most liquids boil when they reach a certain temperature. When crude oil boils, it sends out vapor and condenses. All the different hydrocarbons in crude oil are at different temperatures. And their vapors all make separate liquids. So, in order to separate the hydrocarbons, the scientists distill the crude oil. Because the hydrocarbons boil at different temperatures, their vapors must also condense at different temperatures.When the hydrocarbons boil, their vapors condenses separately. So the oil breaks down into its fractions and forms different liquids.The oil distilled in a very large steel tower, the technical name of which is the “fractionating tower.” The tower is thirty to fifty meters tall and its diameteris one to three meters. It is divided into “chambers”, each of which contains a layer of trays. There are holes in the trays. The vapors go through these holes and condense on the trays. The chambers are at different heights, and the temperature at each height is different. The temperature inside the tower is highest at the bottom, and it is lowest at the top. So each layer of trays is cooler than the layer below it. There are not enough chambers of different temperatures in one tower, so two or three towers are needed.B The chemical industry depends very heavily on petroleum, natural gas, and natural gas liquids as source of raw materials. It is likely that in excess of 90% of the literally thousands of different basic organic chemicals employed today are derived from these sources.The petrochemical industry has grown with the petroleum industry and is considered by some to be a mature industry. However, as is the case with the latest trends in changing crude oil types, it must also evolve to meet changing technological needs.The manufacture of chemicals or chemical intermediates from petroleum and natural gas constituents is an excellent example of the conversion of such materials to more valuable products. The individual chemicals made from petroleum and natural gas are numerous and include industrial chemicals, household chemicals, fertilizers, and paints, as will as intermediates for the manufacture of products, such as synthetic rubber and plastics.Petrochemicals are generally chemical compounds derived from petroleum either by direct manufacture or by indirect manufacture as by-products from the variety of processes that are used during the refining of petroleum. Gasoline, kerosene, fuel oils, lubricating oils, waxes, asphalts, and the like are excluded from the definition of petrochemicals, since they are not, in the true sense, chemical compounds but are in fact intimate mixtures of hydrocarbons.短文2(25分,A、B两篇,只翻译一篇,任选其一)A The energy efficiency of an ethylene plant can be improved in many ways. Modification of a basic plant design to improved energy efficiency can be divided into two categories.(1) Those that reduce the energy requirements of the individual processsteps, and(2) Those that provide these energy requirements in the most efficient manner possible.This article will deal with recent optimization studies that fall into this latter category. The objective in carrying out these studies was to make full use of well-known energy saving principles, while staying within the bounds of proven technology and equipment. Two basic schemes were developed, both based on an energy balanced plant in which neither steam nor electric power are exported or imported.The feature in both schemes that provides the greatest savings in energy is the use of a gas turbine. It is necessary, of course, to recover the sensible heat in the turbine exhaust gas to realize energy savings. In the first scheme, this heat is recovered in a heat recovery boiler. A small amount of supplemental firing is also used here to generate sufficient steam balance. In the second scheme, the gas turbine exhaust is used as combustion air for the pyrolysis furnaces. In this case, steam balance is effected by a small economizer coil, which supplements heat input from the transfer line exchanger system.B The objective of evaporation is to concentrate a solution consisting of a nonvolatile solute and a volatile solvent. In the great majority of evaporations the solvent is water. Evaporation is conducted by vaporizing a portion of the solvent to produce a concentrated solution or thick liquor. Evaporation differs from drying in that residue is a liquid rather than solid; it differs from distillation in that the vapor is usually a single component, and even when the vapor is a mixture, no attempt is made in the evaporation step to separate the vapor into fractions; it differs from crystallization in that emphasis is placed on concentrating a solution rather than forming and building crystals. In certain situations, e.g., in the evaporation of brine to produce common salt, the lie between evaporation and crystallization is far from sharp. Evaporation sometimes produces a slurry of crystals in a saturated mother liquor.Normally, in evaporation the thick liquor is the valuable product and the vapor is condensed and discarded. Mineral-bearing water is often evaporated to give a solid-free product for boiler feed, for special process requirements, or for human consumption. This technique is often called water distillation, buttechnically it is evaporation. Large-scale evaporation process is being developed and used for recovering potable water from sea water. Here the condensed water is the desired product. Only a fraction of the total water in the feed is recovered, and the remainder is discarded.三、汉译英(将下列句子、段落译成英语,共30分)1. 句子翻译(10分)(1)从另一方面说,可供选择的替代燃料也有其缺陷。

For each of them, there are four choices marked A,B,C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.Questions 11-15 are based on the following passage:A mother dolphin(海豚) chats with her baby over the telephone! They were in separate tanks connected by a special underwater audio link.” It seemed clear that they knew who they were talking with” says Don White, whose Project Delphis ran the experiment. But what were they saying?Scientists think dolphins “talk” about everything from basic facts like age to their emotional state. “I speculate that they say things like ‘there are some good fish over here,’or ‘watch out for that shark because he’s hunting.’” says Denise Herzing, who studies dolphins in the Bahamas.Deciphering(译解) “dolphin speak” is also tricky because their language is so dependent on what they’re doing, whether they’re playing, fighting, or going after tasty fish. During fights, for example, dolphins clap(碰撞) their jaws to say “Back off!” But their jaws clap while playing, too as if to show who’s king of the underwater playground.11. How did the mother dolphin talk with her baby over the telephone?A. Two connected tanks were separated for the talk.B. A special underwater audio link was set up for the talk.C. Both the mother dolphin and the baby knew each other.D. A clear voice could be heard in the two separate tanks.12.Dolphins seem to talk to each other about any of the following EXCEPT___.A. their ageB. their emotional stateC. food sourcesD. audio link13. Why is it challenging to interpret “dolphin speak”?A. Because dolphins’ language heavily relies on their actions.B. Because dolphins like to talk about their language.C. Because playing and fighting are part of dolphins’ life.D. Because tasty fish are difficult for dolphins to catch.14. A dolphin might be saying “____” when it claps its jaws.A. Go back to your home!B. Who is playing here!C. I am the king here!D. Show me who the king is!15. When scientists describe dolphins’ communicative skills, their tone is rather___.A. affirmativeB. speculativeC. playfulD. negativeQuestions 16-20 are based on the following passage:An American company has started testing a new program aimed at increasing security. Three workers from , a company that provides security came equipment, have volunteered to be electronically monitored. They will have a silicon chip put inside their arms. The tiny device is the size of a grain of rice and will send out radio signals. These will provide information to a central monitoring system that will give the workers access to secure areas of the workplace. The chips were originally designed for medical purposes.Sean Darks, CEO of City Watcher, said the chips were like identity cards. He said the only difference is that they are inserted inside the person’s body. He added they are very different from Global Positioning Satellite technology, which allows people’s location to be monitored. Mr. Darks insisted that they were not dangerous and even decided to have a chip implanted in his own body. However, many people are worried about the issue of privacy. Many believe the technology could be abused and that new laws will have to be made. Mr. Darks said his workers can always choose to have the chips removed.16. This passage is mainly about__.A. the increasing security of U.S. companies.B. the test of a new security programC. a new central monitoring systemD. Global Positioning Satellite technology17. The three workers from City have___.A. volunteered to provide security camera equipmentB. agreed to have silicon chips planted in their brainC. offered to be monitored in the new security programD. had access to secure areas of their workplace18. Which of the following is NOT true about the silicon chips in trial?A. They are as tiny as a grain of rice.B. They will send out radio signals.C. They function like identity cards.D They will be developed for medical uses.19. The chips are different from the Global Positioning Satellite technology in that ____.A. they are inserted into a person’s body as ID cardsB. they allow people’s location to be monitoredC. they provide information to a central monitoring systemD. they bring more danger to the carriers.20. Many people are worried about the silicon chips because _____.A. they are not assured of the effect of the chips.B. they cannot get the implanted chips removedC. the new laws about the technology might be abusedD. the new technology may intrude on people’s privacyQuestions 21-25 are based on the following passage:In fall 2006, the National Basketball Association (NBA) started using basketballs made with synthetic, or manmade, material instead of leather. They made the switch because they wanted every basketball they use to fell and bounce(弹起) the same.However, some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones. Dallas Mavericks owner Mark Cuban asked for help from the Department of physics at the University of Texas, The scientists investigated friction that affects the ability of a player to hold onto a ball. “The greater the friction, the better it will stick to his hand,” explains Horwitz, one of the physicists who worked on the project.Tests on both wet and dry ball showed that while the plastic ball was easier to grip when dry, it had less friction and became much harder to hold onto when wet. That’s because sweating stays on the surface of the synthetic ball but get absorbed into the leather balls —an important detail for sweaty athletesIn January, the NBA went back to using the traditional leather balls. They aren’t perfect, but for now, that’s just the way the ball bounces.21. The NBA started using synthetic basketballs instead of leather ones because____.A. they wanted every basketball to feel and bounce the sameB. NBA officials wanted a switch with which to start a reformC. they emphasized that synthetic materials are manmadeD.NBA players had used the leather balls for too long a time22.How did some NBA players respond to the switch to synthetic balls?A. They felt much more comfortable with the synthetic balls .B. They thought differently about the leather balls.C. They felt that the new balls were worse than the leather ones.D. They believed the new balls would soon be replaced.23 Which of the following contributes to the better control of the balls?A. Greater friction.B. More ownershipC. Stronger affectionD. Fewer investigations.24. When is it harder for an NBA player to hold onto a synthetic ball?A. When the ball is dried with a towel.B. When the ball is wetted by water.C. When tests are done on the ball.D. When sweating sticks to the ball.25. In the last paragraph ,”that’s just the way the ball bounces” probably means_____.A. tradition offers the best choiceB. the ball bounces ass best it canC. the NBA made a mistakeD, the ball bounces perfectlyQuestions 26-30 are based on the following listing:26.The above listing is most probably___.A. an advertisement placed by an airline companyB. a notice placed by an international air committeeC. an information board provided by a travel agencyD. a ticketing message provided by a hotline company27.

We call this force gravity. This is something we live 22 all the time, and we take it 23 granted and 24 ever think about it. But it is the most important factor in rocket operation and must be overcome if we are to get anywhere in space, or off the ground at all.25 the throwing of a ball as an example. The 26 the ball is thrown, the faster and higher it willgo. What is the secret? Its speed. If we 27 throw the ball hard enough it would go up and up forever and never come down. The speed 28 which it would have to be thrown to do this is 29 as escape speed. Of course, we cannot throw a ball hard enough because the speed30 to escape completely 31 the Earth’s gravity is seven miles per second, or over twenty-five thousand miles per hour.Once escape speed has been 32 by a spacecraft, 33 further power is needed. A rocket aimed 34 the Moon, for 35 , will “coast” (滑行) the rest of the way because the Earth’s. 36 cannot then pull it back, and there is no air resistance in space to slow it down. This “coasting” is known as “free fall. ”That does not mean the rocket is falling down 37 the Earth but that it is traveling 38 in space without the aid of power, 39 a bicycle coasting downhill.Free fall is an important feature of space travel: it would be impossible to carry 40 fuel to provide powered flight all the time.21.

For each of them there are four choices marked A, B, C and D. Read each passage carefully and decide on the best answer. Then write the answer on the ANSWER SHEET.Passage OneBefore the 1500’s, the western plains of North America were dominated by farmers. One group, the Mandans, lived in the upper Missouri River country, primarily in present-day North Dakota. They had large villages of houses built close together. The tight arrangement enabled the Mandans to protect themselves more easily from the attacks of others who might seek to obtain some of food these highly capable farmers stored from one year to the next.The women had primary responsibility for the fields. They had to exercise considerable skill to produce the desired results, for their northern location meant fleeting growing seasons. Winter often lingered; autumn could be ushered in by severe frost. For good measure, during the spring and summer, drought, heat, hail, grasshoppers, and other frustrations might await the wary grower.Under such conditions, Mandan women had to grow maize capable of weathering adversity. They began as early as it appeared feasible to do so in the spring, clearing the land, using fire to clear stubble from the fields and then planting. From this point until the first green corn could be harvested, the crop required labor and vigilance.Harvesting proceeded in two stages. In August the Mandans picked a smaller amount of crop before it had matured fully. This green corn was boiled, dried, and shelled, with some of the maize slated for immediate consumption and the rest stored in animal-skin bags. Later in the fall, the people picked the rest of the corn. They saved the best of the harvest for seeds or for trade, with the remainder eaten right away or stored for later use in underground reserves. With appropriate banking of the extra food, the Mandans protect themselves against the disaster of crop failure and accompanying hunger.The women planted another staple, squash, about the first of June, and harvested it near the time of the green corn harvest. They picked it, dried it, and strung the slices before they stored them. Once again, they saved the seed from the best of the year’s crop. The Mandans also grew sunflowers and tobacco; the latter was the particular task of the old men.41. The Mandans build their houses close together in order to ______.A. guard their supplies of foodB. protect themselves against the weatherC. allow more room for growing cornD. share farming implements42. Why does the author believe that the Mandans were skilled farmers?A. They developed effective fertilizers.B. They developed new varieties of corn.C. They could grow crops in most types of soil.D. They could grow crops despite adverse weather.43. Which of the following processes does the author imply was done by both men and women?A. Clearing fieldsB. Planting corn.C. Harvesting corn.D. Harvesting squash.44. According to the passage, the Mandans preserve their food by ______.A. smokingB. dryingC. freezingD. squash45. Which of the following crops was cultivated primarily by men?A. Corn.B. Squash.C. Sunflower.D. Tobacco.Passage TwoWe’ve already pushed the world oceans close to—and in some cases, past—their natural limits, according to a recently released report on the state of our oceans by the World Watch Institute.The increasing number of citizen groups, businesses and governments taking an active interest in slowing down the destruction and pollution of the ocean is encouraging, says senior researcher and author Anne Platt McGinn, citing a host of efforts already under way: 1. Unilever, which controls 20 percent of the whitefish market in Europe and US, has agreed to buy only fish caught and produced in an environmentally sustainable manner. 2. Volunteers in the Philippines, Thailand, India and Ecuador are replanting mangrove areas to repair earlier damage from shrimp farming. 3. In northern Sulawesi, citizens have cleared coral reefs of harmful invasive species. 4. The United States and Canada have each banned oil drilling on large portions of their continental shelves.On the downside, Safeguarding the Health of Oceans says that seven out of ten commercial fish species are fully or overexploited, and even worse, many of their spawning grounds have been cleared to make room for shrimp ponds, golf courses and beach resorts. Habitat degradation, resulting from development, agricultural run off, sewage pollution and destructive fishing practices has led to a tripling in the number of poisonous algal species identified by scientists, increasing fish kills, beach closures, and economic losses.The impact on the economy is significant. People obtain an average of 16 percent of their animal protein from fish, and people in developing countries are extremely dependent on reef fisheries for both food and income. Tourism accounts for a large piece of coastline economies and medicines are being found in reef ecosystems every day. Even toothpaste and ice cream depend on the gel-forming properties of brown algae.The problems facing the oceans are legion: the marine conservation community is fragmented, bans on destructive activities are routinely ignored, too many regulatory organizations have a development-first mindset and enforcement and oversight are ineffective, if not altogether lacking.Oceans need to be protected locally, nationally and internationally, according to McGinn. Right now, the United Nations General Assembly spends just one day a year covering issues that affect more than half of the planet. The report suggests that a tax of one tenth of one percent on industrial and recreational ocean activities would generate $500 million a year, more than five times the annual budgets of the International Maritime Organization and the Fisheries Department of the U. N. Food and Agriculture Organization.However, the most productive areas of the ocean are under national jurisdiction and 80 percent of oceanic pollution originates on land. This means that addressing global marine issues requires strong national and local policies.Problems remain far from resolved.46. The word “sustainable” in Paragraph 2 is closest in meaning to ______.A. maintainableB. reasonableC. understandableD. respectable47. What’s the probable relationship between mangrove growing and shrimp farming in the Philippines?A. The growth of mangroves kept shrimps from reproducing.B. Large areas of mangroves were damaged because of shrimp farming.C. Mangroves helped shrimps grow fast.D. Shrimp farming gave rise to rapid growth of mangroves.48. Which of the following statements is not the result of destructive fishing practices?A. Seventy percent commercial fish species are over exploited.B. Many of fishes’ spawning grounds have been destroyed.C. Economic losses are on the increase.D. Each country has already taken measures to ban destructive activities.49. What will happen if an organization takes a development—first attitude in environmental context?A. It will take strong measures to prevent oceans from being further polluted.B. It is going to exploit the oceanic resources first regardless of environmental protection.C. It will not ignore bans on destructive activities.D. It will not place development above other factors.50. We can infer from the passage that ______.A. problems at the international level continue to be difficult to resolveB. all countries are going to impose taxes on fishers and touristsC. the UN General Assembly has made strong policies with regard to oceanic protectionD. the problems facing the oceans have already aroused sufficient attentionPassage ThreeLast Christmas season, Michelle Speetzen’s life was like yours: Mall Hell. Enduring hour-long traffic jams on the road from her suburban home to Willowbreek Mall, the 36-year-old mom would puff on her shopping list and get back in the car to fight traffic headed for other packed stores. The craziest moment came when she triumphantly got hold of a coveted Sleep-N-Snore— the key to her 5-year-old son’s happiness and barely escaped a mob of similarly desperate parents who’d picked up the scent of fake fur.But this year, Speetzen has it wired. After young Dylan’s bedtime, she steals to the spare bedroom upstairs, her face illuminated by the glow of her computer. And mouseclick by mouseclick, her shopping list shrinks. Her crowning achievement came last Friday when she painfully realized that Dylan had his little heart set on this year’s must-have-but-impossible-to-get toy, the baffling, babbling Furby. After 20 minutes of Web-browsing she located one at America Online’s shopping site. It cost more than three times the $30 list price. “Hey, I want it under the tree for my son,” she says. “It will be at my door in a few days, and I don’t have to fight anybody in a store. ”Michelle Speetzen represents the advance guard of an army that’s about to change not only the nature of holiday shopping, but the face of retailing itself. After years of failing to live up to exaggerated promises, e-commerce — online buying—is finally taking off. All over America, millions set out to procure presents over the Internet — and many of them are succeeding. “This isn’t going to be a white Christmas,”says Amazon. com founder Jeff Bezos. “It’s going to be a Web Christmas. ”True, even in this breakthrough year, the estimated $2. 3 billion Americans will spend on Web gifts is only a fraction of the total holiday sales. But it’s well over double last year’s total, and many people expect a threefold increase in Christmas sales. You can view this year-end boom as the culmination of a lucrative trend. According to Jupiter Communications, almost 17 million people will buy something from a Web site this year, up from 10 million last year and 5 million in 1996. Within a decade, the Jupiter people believe, the mouseclickers will eclipse catalog buyers.51. Mall Hell (Line 1, Paragraph 1) means ______.A. the painful experience of people doing holiday shoppingB. the chaotic condition of shopping mallsC. the long traffic jams from suburbs to downtown shopping centersD. the desperation of parents who bought faulty goods52. Sleep-N-Snore (Line 5, Paragraph 1) is most probably a ______.A. computer gameB. toy animalC. small boy’s keyD. famous brand53. It can be inferred from the passage that ______.A. e-sales had fallen short of expectation until this yearB. electronic commerce grew faster than predictedC. the volume of e-sales had been exaggeratedD. it’s cheaper to buy over the Internet than at the mall54. Which of the following statements is true?A. Most people now prefer to shop over the Internet.B. The number of e-mail shoppers is likely to surpass that of conventional shoppers in ten years’ time.C. With the emergence of electronic commerce, the holiday sales have increased significantly.D. Some popular toys are impossible to procure except from a Web site.55. This passage is mainly about ______.A. the difficulty in getting holiday presentsB. electronic shoppingC. Christmas salesD. the growth of computer networksPassage FourOne of the more discernible trends in the financial-service industry in recent times has been the adoption of programs designed to encourage more personalized relationships between an institution’s employees and its clients, particularly those clients who are major depositors. The expression most commonly used to describe this type of program is “relationship banking”. A good definition is provided in the 1985 book Marketing Financial Services:In relationship banking the emphasis is on establishing a long-term, multiple-service relationship; on satisfying the totality of the client’s financial service needs; on minimizing the need or desire of clients to splinter their financial business among various institutions.Implicit within any definition of relationship banking is recognition that the financial-service requirements of one individual or relatively homogeneous group will likely be substantially different from those of another individual or group. A successful relationship banking program is, therefore, dependent in a large part on the development of a series of financial—service “packages”, each designed to meet the needs of identifiably homogeneous groups.Another dimension of relationship banking is the development of highly personalized relationships between employee and client. In most financial institutions today the client is serviced by any employee who happens to be free at the time, regardless of the nature of the transaction. Personalized relationships are therefore difficult to establish. In a full relationship banking program, however, the client knows there is one individual within the institution who has intimate knowledge of the client’s requirements and preferences regarding complex transactions. Over time, the client develops a high level of confidence in this employee. In short, a personalized relationship evolves between client and employee.56. With what subject is the passage mainly concerned?A. The decline of the financial-service industry.B. Variety within financial services.C. A way of making banking more personal.D. Increasing everyday banking transactions.57. Which of the following can be inferred from the passage about relationship banking programs?A. They have recently been discontinued.B. They are already being used.C. They will shortly be used.D. They will be used in the distant future.58. What is the meaning of the word “institutions” in the first paragraph?A. Banks.B. Schools.C. Hospitals.D. Police stations.59. According to the definition of relationship banking quoted in the passage, one of the main aims of this type of banking is to encourage clients to ______.A. consult with each other concerning their financesB. keep all their business with a single bankC. recognize their own bankingD. keep their financial requirement to a minimum60. According to the passage, what is a necessary first step in instituting relationship banking?A. Resigning bank buildings.B. Hiring congenial staff who makes clients welcome.C. Recognizing the needs of groups and individuals.D. Teaching bank employees to be more confident.Part IV.

中国石油化工集团公司2007年工程系列高级任职资格外语考试试卷英语(炼化工程)(120分钟内完成)一、阅读理解(阅读短文,简要回答问题,共25分)短文1(12.5分)Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. Banks may agree to provide short-term finance, they are generally unwilling to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits, this they do by issuing stocks and shares in the business through The Stock Exchange. By doing so they can put into circulation the savings of individuals and institutions, both at home and overseas.When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seeking to invest his money.Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, local authorities, and nationalized industries therefore frequently needed to borrow money to finance major capital spending, and they, too, come to The Stock Exchange.1. What must almost all companies involved in new production and development depend on according to the passage?2. How is the money which enables these companies to go ahead with their projects raised?3. What do the savers do when they want their money back?4. In what conditions are all the essential services on which we depend?5. Why do companies invite people to lend money to them or take a share in the business?短文2(12.5分)Like street–corner prophets proclaiming that the end is near, scientists who study the earth’s atmosphere have been issuing predictions of impending doom for the past few years without offering any concrete proof. So far even the experts have had to admit that no solid evidence has emerged that this is anything but a natural phenomenon. And the uncertainty has given skeptics—especially Gingrichian politicians—plenty of ammunition to argue against taking the difficult, expensive steps required to stave off a largely hypothetical calamity.Until now, a draft report currently circulating on the Internet asserts that the global-temperature rise can now be blamed, at least in part, on human activity. Statements like this have been made before by individual researchers—who have been criticized for going too far beyond the scientific consensus. But this report comes from the International Panel on Climate Change(IPCC), a respected UN-sponsored body made up of more than 1,500 leading climate experts from 60 nations.This shift in scientific consensus is based not so much on new data as on improvements in the complex computer models that climatologists use to test their theories. Unlike chemists or molecular biologists, climate experts have no way to do lab experiments on their specialty. So they simulate them on supercomputers and look at what happens when human-generated gases —carbon dioxide from industry and auto exhaust, methane from agriculture, chlorofluoro-carbon from leaky refrigerators and spray cans—are pumped into the model’s virtual atmospheres.Until recently, the computer models weren’t working very well. When the scientists tried to simulate what they believe has been happening over the past century or so, the results didn’t mesh with reality; the models said the worldshould now be warmer than it actually is. The reason is that the computer models had been overlooking an important factor affecting global temperatures; sulfur dioxide that are produced along with CO2 when fossil fuels are burned in cars and power plants. Aerosols actually cool the planet by blocking sunlight and mask the effects of global warming.Once the scientist factored in aerosols, their models began looking more like the real world. The improved performance of the simulations was demonstrated in 1991, when they successfully predicted temperature changes in the aftermath of the massive Mount Pinatubo eruption in the Philippines. A number of studies since have added to the scientists’confidence that they finally know what they’re talking about—and can predict what may happen if green house gases continue to be pumped into the atmosphere unchecked.1. Why can’t scientists and experts offer any concrete proof of impending doom?2. What does a current draft report on the Internet confirm?3. How do climate experts do lab experiments on their specialty?4. What important factor mentioned in paragraph four can also affects global temperatures?5. The simulated computer models are proved reliable when__________.二、英译汉(将下列短文译成汉语,共45分)短文1(20分,A、B两篇,只翻译一篇,任选其一)A How do scientists separate the hydrocarbons? They distil the oil. They turn the oil into vapor and then turn the vapor into liquids.The theory of distillation is very easy. Most liquids boil when they reach a certain temperature. When crude oil boils, it sends out vapor and condenses. All the different hydrocarbons in crude oil are at different temperatures. And their vapors all make separate liquids. So, in order to separate the hydrocarbons, the scientists distill the crude oil. Because the hydrocarbons boil at different temperatures, their vapors must also condense at different temperatures.When the hydrocarbons boil, their vapors condenses separately. So the oil breaks down into its fractions and forms different liquids.The oil distilled in a very large steel tower, the technical name of which is the “fractionating tower.” The tower is thirty to fifty meters tall and its diameteris one to three meters. It is divided into “chambers”, each of which contains a layer of trays. There are holes in the trays. The vapors go through these holes and condense on the trays. The chambers are at different heights, and the temperature at each height is different. The temperature inside the tower is highest at the bottom, and it is lowest at the top. So each layer of trays is cooler than the layer below it. There are not enough chambers of different temperatures in one tower, so two or three towers are needed.B The chemical industry depends very heavily on petroleum, natural gas, and natural gas liquids as source of raw materials. It is likely that in excess of 90% of the literally thousands of different basic organic chemicals employed today are derived from these sources.The petrochemical industry has grown with the petroleum industry and is considered by some to be a mature industry. However, as is the case with the latest trends in changing crude oil types, it must also evolve to meet changing technological needs.The manufacture of chemicals or chemical intermediates from petroleum and natural gas constituents is an excellent example of the conversion of such materials to more valuable products. The individual chemicals made from petroleum and natural gas are numerous and include industrial chemicals, household chemicals, fertilizers, and paints, as will as intermediates for the manufacture of products, such as synthetic rubber and plastics.Petrochemicals are generally chemical compounds derived from petroleum either by direct manufacture or by indirect manufacture as by-products from the variety of processes that are used during the refining of petroleum. Gasoline, kerosene, fuel oils, lubricating oils, waxes, asphalts, and the like are excluded from the definition of petrochemicals, since they are not, in the true sense, chemical compounds but are in fact intimate mixtures of hydrocarbons.短文2(25分,A、B两篇,只翻译一篇,任选其一)A The energy efficiency of an ethylene plant can be improved in many ways. Modification of a basic plant design to improved energy efficiency can be divided into two categories.(1) Those that reduce the energy requirements of the individual processsteps, and(2) Those that provide these energy requirements in the most efficient manner possible.This article will deal with recent optimization studies that fall into this latter category. The objective in carrying out these studies was to make full use of well-known energy saving principles, while staying within the bounds of proven technology and equipment. Two basic schemes were developed, both based on an energy balanced plant in which neither steam nor electric power are exported or imported.The feature in both schemes that provides the greatest savings in energy is the use of a gas turbine. It is necessary, of course, to recover the sensible heat in the turbine exhaust gas to realize energy savings. In the first scheme, this heat is recovered in a heat recovery boiler. A small amount of supplemental firing is also used here to generate sufficient steam balance. In the second scheme, the gas turbine exhaust is used as combustion air for the pyrolysis furnaces. In this case, steam balance is effected by a small economizer coil, which supplements heat input from the transfer line exchanger system.B The objective of evaporation is to concentrate a solution consisting of a nonvolatile solute and a volatile solvent. In the great majority of evaporations the solvent is water. Evaporation is conducted by vaporizing a portion of the solvent to produce a concentrated solution or thick liquor. Evaporation differs from drying in that residue is a liquid rather than solid; it differs from distillation in that the vapor is usually a single component, and even when the vapor is a mixture, no attempt is made in the evaporation step to separate the vapor into fractions; it differs from crystallization in that emphasis is placed on concentrating a solution rather than forming and building crystals. In certain situations, e.g., in the evaporation of brine to produce common salt, the lie between evaporation and crystallization is far from sharp. Evaporation sometimes produces a slurry of crystals in a saturated mother liquor.Normally, in evaporation the thick liquor is the valuable product and the vapor is condensed and discarded. Mineral-bearing water is often evaporated to give a solid-free product for boiler feed, for special process requirements, or for human consumption. This technique is often called water distillation, buttechnically it is evaporation. Large-scale evaporation process is being developed and used for recovering potable water from sea water. Here the condensed water is the desired product. Only a fraction of the total water in the feed is recovered, and the remainder is discarded.三、汉译英(将下列句子、段落译成英语,共30分)1. 句子翻译(10分)(1)从另一方面说,可供选择的替代燃料也有其缺陷。
