Read the passages and then mark your answers on your coloured answer sheet~TEXT AHostility to Gypsies has existed almost from the time they first appeared in Europe in the 14th century. The origins of the Gypsies, with little written history, were shrouded in mystery. What is known now from clues in the various dialects of their language, Romany, is that they came from northern India to the Middle East a thousand years ago, working as minstrels and mercenaries, metal-smiths and servants. Europeans misnamed them Egyptians, soon shortened to Gypsies. A clan system, based mostly on their traditional crafts and geography, has made them a deeply fragmented and fractious people, only really unifying in the face of enmity from non-Gypsies, whom they call gadje. Today many Gypsy activists prefer to be called Roma, which comes from the Romany word for “man”. But on my travels among them most still referred to themselves as Gypsies.In Europe their persecution by the gadje began quickly, with the church seeing heresy in their fortune-telling and the state seeing anti-social behaviour in their nomadism. At various times they have been forbidden to wear their distinctive bright clothes, to speak their own language, to travel, to marry one another, or to ply their traditional crafts. In some countries they were reduced to slavery it wasn't until the mid-1800s that Gypsy slaves were freed in Romania. In more recent timesthe Gypsies were caught up in Nazi ethnic hysteria, and perhaps half a million perished in the Holocaust. Their horses have been shot and the wheels removed from their wagons, their names have been changed, their women have been sterilized, and their children have been forcibly given for adoption to non-Gypsy families.But the Gypsies have confounded predictions of their disappearance as a distinct ethnic group and their numbers have burgeoned. Today there are an estimated 8 to 12 million Gypsies scattered across Europe, making them the continent's largest minority. The exact number is hard to pin down. Gypsies have regularly been undercounted, both by regimes anxious to downplay their profile and by Gypsies themselves, seeking to avoid bureaucracies. Attempting to remedy past inequities, activist groups may overcount. Hundreds of thousands more have emigrated to the Americas and elsewhere. With very few exceptions Gypsies have expressed no great desire for a country to call their own -unlike the Jews, to whom the Gypsy experience is often compared. “Romanestan” said Ronald Lee, the Canadian Gypsy writer, "is where my two feet stand."16. Gypsies are united only when theyA are engaged in traditional crafts.B. call themselves Roma.C. live under a clan system.D. face external threats.17. In history hostility to Gypsies in Europe resulted in their persecution by all the followingEXCEPTA. the Egyptians.B the state.C. the church.D. the Nazis.18. According to the passage, the main difference between the Gypsies and the Jews lies in their concepts ofA.language.B. culture.C. identity.D. custom.TEXT BI was just a boy when my father brought me to Harlem for the first time, almost 50 years ago. We stayed at the Hotel Theresa, a grand brick structure at 125th Street and Seventh Avenue. Once, in the hotel restaurant, my father pointed out Joe Louis. He even got Mr. Brown, the hotel manager, to introduce me to him, a bit paunchy but still the champ as far as I was concerned.Much has changed since then. Business and real estate are booming. Some say a new renaissance is under way. Others decry what they see as outside forces running roughshod over the old Harlem.New York meant Harlem to me, and as a young man I visited it whenever I could. But many of my old haunts are gone. The Theresa shut down in 1966. National chains thatonce ignored Harlem now anticipate yuppie money and want pieces of this prime Manhattan real estate. So here I am on a hot August afternoon, sitting in a Starbucks that two years ago opened a block away from the Theresa, snatching at memories between sips of high-priced coffee. I am about to open up a piece of the old Harlem- the New York Amsterdam News—when a tourist asking directions to Sylvia's, a prominent Harlem restaurant, penetrates my daydreaming. He's carrying a book: Touring Historic Harlem.History. I miss Mr. Michaux's bookstore, his House of Common Sense, which was across from the Theresa. He had a big billboard out front with brown and black faces painted on it that said in large letters: "World History Book Outlet on 2,000,000,000 Africans and Nonwhite Peoples." An ugly state office building has swallowed that space.I miss speaker like Carlos Cooks, who was always on the southwest comer of 125th and Seventh, urging listeners to support Africa. Harlem's powerful political electricity seems unplugged-although the sweets are still energized, especially by West African immigrants.Hardworking southern newcomers formed the bulk of the community back in the 1920s and'30s, when Harlem renaissance artists, writers, and intellectuals gave it a glitter and renown that made it the capital of black America. From Harlem, W.E.B. DuBois, Langston Hughes, Paul Robeson, Zora Neal Hurston, and others helped power America's cultural influence around the world.By the 1970s and '80s drugs and crime had ravaged parts of the community. And the life expectancy for men in Harlem was less than that of men in Bangladesh. Harlem had become a symbol of the dangers of inner-city life.Now, you want to shout “Lookin’good!”at this place that has been neglected for so long. Crowds push into Harlem USA, a new shopping centre on 125th, where a Disney store shares space with HMV Records, the New York Sports Club, and a nine-screen Magic Johnson theatre complex. Nearby, a Rite Aid drugstore also opened. Maybe part of the reason Harlem seems to be undergoing a rebirth is that it is finally getting what most people take for granted.Harlem is also part of an “empowerment zone”—a federal designation aimed at fostering economic growth that will bring over half a billion in federal, state, and local dollars. Just the shells of once elegant old brownstones now can cost several hundred thousand dollars. Rents are skyrocketing. An improved economy, tougher law enforcement, and community efforts against drugs have contributed toa 60 percent drop in crime since 1993.19. At the beginning the author seems to indicate that HarlemA. has remained unchanged all these years.B. has undergone drastic changes.C. has become the capital of Black America.D. has remained a symbol of dangers of inner-city life.20. When the author recalls Harlem in the old days, he has a feeling ofA. indifference.B, discomfort.C. delight.D. nostalgia.21. Harlem was called the capital of Black America in the 1920s and '30s mainly because of itsA. art and culture.B. immigrant population.C. political enthusiasm.'D. distinctive architecture.22. From the passage we can infer that, generally speaking, the authorA. has strong reservations about the changes.B. has slight reservations about the changes,C. welcomes the changes in Harlem.D. is completely opposed to the changes.TEXT CThe senior partner, Oliver Lambert, studied the resume for the hundredth time and again found nothing he disliked about Mitchell Y. McDeere, at least not on paper. He had the brains, the ambition, the good looks. And he was hungry; with his background, he had to be. He was married, and that was mandatory. The firm had never hired an unmarried lawyer, and it frowned heavily on divorce, as well as womanizing and drinking. Drug testing was in the contract. He had a degree in accounting, passed the CPA exam the first time he took it and wanted to be a tax lawyer, which of course was a requirement with a tax firm. He was white, and the firm had never hired a black. They managed this by being secretive and clubbish and never soliciting job applications. Other firms solicited, and hired blacks. This firm recruited, and remained lily white. Plus, the firm was in Memphis, and the top blacks wanted New York or Washington or Chicago. McDeere was a male, and there were no women in the firm. That mistake had been made in the mid-seventies when they recruited the number one grad from Harvard, who happened to be a she and a wizard at taxation. She lasted four turbulent years and was killed in a car wreck.He looked good, on paper. He was their top choice. In fact, for this year there were no other prospects. The list was very short. It was McDeere, or no one.The managing partner, Royce McKnight, studied a dossier labeled "Mitchell Y. McDeere-Harvard." An inch thick with small print and a few photographs; it had been prepared by some ex-CIA agents in a private intelligence outfit in Bethesda. They were clients of the firm and each year did the investigating for no fee. It was easy work, they said, checking out unsuspecting law students. They learned, for instance, that he preferred to leave the Northeast, that he was holding three job offers, two in New York and one in Chicago, and that the highest offer was $76,000 and the lowest was $68,000. He was in demand. He had been given the opportunity to cheat on a securities exam during his second year. He declined, and made the highest grade in the class. Two months ago he had been offered cocaine at a law school party. He said no and left when everyone began snorting. He drank an occasional beer, but drinking was expensive and he had no money. He owed close to $23,000 in student loans. He was hungry.Royce McKnight flipped through the dossier and smiled. McDeere was their man. Lamar Quin was thirty-two and not yet a partner. He had been brought along to look young and act young and project a youthful image for Bendini, Lambert & Locke, which in fact was a young firm, since most of the partners retired in their late forties or early fifties with money to bum. He would make partner in this firm. With a six-figure income guaranteed for the rest of his life, Lamar could enjoy the twelve-hundred-dollar tailored suits that hung so comfortably from his tall, athletic frame. He strolled nonchalantly across the thousand-dollar-a-day suite and poured another cup of decaf. He checked his watch. He glanced at the two partners sitting at the small conference table near the windows.Precisely at two-thirty someone knocked on the door. Lamar looked at the parmers, who slid the resume and dossier into an open briefcase. All three reached for their jackets. Immar buttoned his top button and opened the door.23. Which of the following is NOT the firm’s recruitment requirement?A. Marriage.B. Background.C. Relevant degree.D. Male.24. The details of the private investigation show that the firmA. was interested in his family background.B. intended to check out his other job offers.C. wanted to know something about his preference.D. was interested in any personal detail of the man.25. According to the passage, the main reason Lama Quin was there at the interview was thatA. his image could help impress McDereer.B. he would soon become a partner himself.C. he was good at interviewing applicants.D. his background was similar to MeDereer's.26. We get the impression from the passage that in job recruitment the firm was NOTA. selective.B. secretive.C. perfunctory.D. racially biased.TEXT KFirst read the questions.39. When did Moore receive his first commission?A. In 1948.B. In 1946.C. In 1931.D. In 1928.40. Where did Moore win his first international prize?A. In London.B. In Venice.C. In New York.D. In Hamburg.Now go through TEXT K quickly to answer questions 39 and 40.Henry Moore, the seventh of eight children of Raymond Spencer Moore and his wife Mary, was born in Yorkshire on 30 July 1898. After graduating from secondary school, Moore taught for a short while. Then the First World War began and he enlisted in the army at the age of eighteen. After the war he applied for and received an ex-serviceman's grant to attend Leeds School of Art. At the end of his second year he won a scholarship to the Royal College of Art in London.In 1928 Moore met Irina Radetsky, a painting student at the college, whom he married a year later. The couple then moved into a house which consisted of a small ground-floor studio with an equally small flat above. This remained their London home for ten years.Throughout the 1920's Moore was involved in the art life of London. His first commission, received in 1928, was to produce a sculpture relief for the newly opened headquarters of London Transport. His first one-man exhibition opened at the Warren Gallery in 1928; it was followed by a show at the Leicester Galleries in 1931 and his first sale to a gallery abroad- the Museum fur Kunst und Gewerbe in Hamburg. His success continued.In 1946 Moore had his first foreign retrospective exhibition at the Museum of Modem Art, New York. In 1948 he won the International Sculpture Prize at the 24th Venice Biennale, the first of countless international accolades acquired in succeeding years. At the same time sales of Moore's work around the world increased, as did the demand for his exhibitions. By the end of 1970's the number of exhibitions had grown to an average of forty a year, ranging from the very small to major international retrospectives taking years of detailed planning and preparation. The main themes in Moore's work included the mother and child, the earliest work created in 1922, and the reclining figure dating from 1926. At the end of the 1960's came stringed figures based on mathematical models observed in the Science Museum, and the first helmet head, a subject that later developed into the internal-external theme- variously interpreted as a hard form coveting a soft, like a mother protecting her child or a foetus inside a womb.A few years before his death in 1986 Moore gave the estate at Perry Green with its studios, houses and cottages to the Trustees of the Henry Moore Foundation to promote sculpture and the fine arts within the cultural life of the country and in particular the works of Henry Moore.ANSWER SHEET ONEPART I LISTENING COMPREHENSIONSECTION D NOTE-TAKING & GAPFILING (15 MIN)Fill in each of the gaps with ONE word You may refer to your notes.

When a natural history museum wants an exhibition, it must often build it.Demographic indicators show that Americans in the postwarperiod were more eager than ever to establish families.

Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题(20分)最著名的互联网例子是因特网。

Passage 1:Nowadays, with the rise of electronic devices, the habit of reading seems to be declining among young people. Many argue that traditional books will soon become obsolete. However, a study conducted by the University of Sussex suggests otherwise.According to the study, reading books not only provides entertainment but also has numerous mental health benefits. Regular reading can improve cognitive abilities, enhance concentration, and even prevent cognitive decline in old age. The study also indicates that reading fiction can improve empathy and enhance social skills.Furthermore, reading physical books promotes better sleep quality. Unlike electronic devices such as tablets or smartphones, which emit blue light and disrupt sleep patterns, traditional books do not have such negative effects on sleep. This makes reading before bedtime an excellent option for achieving sound and restful sleep.In conclusion, while electronic devices offer convenience, there are still significant benefits to be gained from reading traditional books. Therefore, it is essential to encourage and cultivate the habit of reading among young people.3. According to the study conducted by the University of Sussex, reading books can _______.A. improve physical healthB. prevent cognitive declineC. enhance concentration答案:B. prevent cognitive decline解析:这道题目要求根据文章的内容选择正确答案。

It was that strange hour in downtown New York when the workers were pouring homeward in the twilight. I marched among thousands of tired men and women whom the factory whistles had unyoked. They flowed in rivers through the clothing factory districts, then down along the avenues to the East Side.I met my father near Cooper Union. I recognized him, a hunched, frozen figure in an old overcoat standing by a banana cart. He looked so lonely, the tears came to my eyes. Then he saw me, and his face lit with his sad, beautiful smile -Charlie Chaplin's smile."Arch, it's Mikey," he said. "So you have sold your papers! Come and eat a banana." He offered me one. I refused it. I felt it crucial that my father sell his bananas, not give them away. He thought I was shy, and coaxed and joked with me, and made me eat the banana. It smelled of wet straw and snow."You haven't sold many bananas today, pop," I said anxiously.He shrugged his shoulders."What can I do? No one seems to want them."It was true. The work crowds pushed home morosely over the pavements. The rusty skydarkened over New York building, the tall street lamps were lit, innumerable trucks, street cars and elevated trains clattered by. Nobody and nothing in the great city stopped for my father's bananas."I ought to yell," said my father dolefully. "I ought to make a big noise like other peddlers, but it makes my throat sore. Anyway, I'm ashamed of yelling, it makes me feel like a fool. "I had eaten one of his bananas. My sick conscience told me that I ought to pay for it somehow. I must remain here and help my father."I'll yell for you, pop," I volunteered."Arch, no," he said, "go home; you have worked enough today. Just tell momma I'll be late."But I yelled and yelled. My father, standing by, spoke occasional words of praise, and said I was a wonderful yeller. Nobody else paid attention. The workers drifted past us wearily, endlessly; a defeated army wrapped in dreams of home. Elevated trains crashed; the Cooper Union clock burned above us; the sky grew black, the wind poured, the slush burned through our shoes. There were thousands of strange, silent figures pouring over the sidewalks in snow. None of them stopped to buy bananas.I yelled and yelled, nobody listened.My father tried to stop me at last. "Nu," he said smiling to console me, "that was wonderful yelling. Mikey. But it's plain we are unlucky today! Let's go home."I was frantic, and almost in tears. I insisted on keeping up my desperate yells. But at last my father persuaded me to leave with him.11.

A business firm chooses the price that maximizesits net revenues, irrespective fluctuations in income; and increasingly the ___2 outlook of universities in the United States is indistinguishable from those of ___3 business firms. The rise in tuitions mayreflect the fact economic uncertainty ___4 increases the demand for education. The biggest cost of beingin the school is foregoing income from a job (this isprimarily a factor in ___5 graduate and professional-school tuition); the poor one' s job prospects, ___6 the more sense it makes to reallocate time from the job market to education,in order to make oneself more marketable. The ways which universities make themselves attractive to students ___7include soft majors, student evaluations of teachers, giving studentsa governance role, and eliminate required courses. ___8Sky-high tuitions have caused universities to regard their students as customers. Just as business firms sometimes collude to shorten the ___9rigors of competition, universities collude to minimize the cost to them of the athletes whom they recruit in order to stimulate alumni donations, so the best athletes now often bypass higher education in order to obtain salaries earlier from professional teams. And until they were stopped by the antitrust authorities, the Ivy League schools colluded to limit competition for the best students, by agreeing not to award scholarships on the basis of merit rather than purelyof need-just like business firms agreeing not to give discounts on their best ___10 customer.PART V TRANSLATION (60 MIN)提示:今年专八翻译部分的选材均出自《散文佳作108篇(汉英•英汉对照)》作者:乔萍翟淑蓉宋洪玮,建议大家熟读此书。

1.Why are cast metal sheet ingots hot-rolled first instead of being cold-rolled?Because of cold rolling is to use hot rolled steel coils as the raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts2.What type of heat treatment is given to the rolled metal sheet after hot and“warm” rolling? What is its purpose?轧钢的热处理的类型?轧钢热处理的目的?Heat treatment of the main types are annealing, normalizing, quenching and tempering, solution treatment and aging treatment, cold treatment, chemical treatment, etc.Annealing:The steel is heated to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Steel annealing is a heat the steel to the phase change or part of the phase change temperature, slow cooling after heat preservation heat treatment method. The purpose of annealing is to eliminate tissue defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the steel, reduce residual stress; Can decrease the hardness at the same time, improve the plasticity and toughness, improve machinability. So before annealing in order to eliminate and improve both the legacy of tissue defects and internal stress, and to prepare for the follow-up process, so the annealing is belong to the intermediate heat treatment, also called heat treatment in advance Normalizing:Normalizing is heated to above the critical temperature of steel, to all into homogeneous austenitic steel, heat treatment and natural cooling in air. It can eliminate hypereutectoid steel mesh cementite, for hyposteel normalizing can refine crystal lattice, improve comprehensive mechanical properties, low requirements for the parts use the normalized instead of the annealing process is more economic.Quenching:Quenching is the steel is heated to above the critical temperature, heat preservation for a period of time, then quickly into the quenching medium, the temperature plummeted, rapid cooling at greater than the critical cooling rate of speed, which is mainly composed of martensite and unbalanced heat treatment method of the organization. Can increase strength and hardness of the steel quenching, but to reduce its plasticity. That is commonly used in quenching hardening agent are: water, oil, caustic soda, and salt solution, etc3.How are metal alloys made by the casting process? (b) Distinguish betweenwrought alloy products and cast alloy products.金属铸造合金的过程是怎样的?区分可锻合金产品和铸造合金产品。
First stage: liquid contraction, the metal liquid from a cooled to near liquidus temperature contraction, when the falling of the liquid surface in the casting.The second stage: solidification shrinkage, the metal solidification, the contraction of the shift from liquid into solidThe third stage: solid shrinkage, i.e., the shrinkage of metal during solidification cooling to room temperature after, this process of contraction is not uniform, because in the process of phase change.Forging belongs to building materials industry, has many USES, from the concept: forging is a metal pressure, through the shape of the plastic deformation shape requirements or suitable compression force. Forgings in the process of manufacturing is to use a hammer or pressure that power. And in the process of casting, change the structure and physical properties of metal particlesAccording to the model of sand mold, material according to your drawings to melt into a liquid, pour the liquid into the sand mould, unpacking after solidification, out from the sand, and the model of object is casting4.Distinguish between elastic and plastic deformation (use schematics).弹性应变和塑性应变的区别Material deformation under the external force, when the external force to cancel, mate rial deformation can disappear and be able to fully recover the original shape of prope rty is called elasticity.This recoverable deformation is called elastic deformation. Plastic deformation is the material - including fluid and solid under certain conditions, deformation under the action of external force, when imposed by external forces to re move or disappear after the object cannot be reinstated a physical phenomenon.5.Define (a) engineering stress and strain, and (b) true stress and strain, (c)Distinguish between tensile/compressive stress (also called normal stress) and shear stress, (d) Distinguish between tensile/compressive strain (also called normal strain) and shear strain.定义工程应变和应力、真应力应变、区分拉伸/压缩应力和剪切应力、区分拉伸/压缩应变和剪切应变The shape of the curve reaction material under the action of external force of brittleness, plasticity, yield, such as the deformation fracture process.The stress-straincurve is usually referred to as the engineering stress-strain curve.True stress - strain curve, because the area of the sample at any instant in the process of drawing A and gage length L (L = L0 + delta L) are changing frequently, the nominal stress and the nominal strain is calculated on the initial area of A0 and standard of L0.At the exit of specimens under tensile stress, the value of the force imposed by the ratio of the sample of the original cross-sectional area, the unit for the MPaIn the process of compression test, and try them on compression load divided by the value of the original cross-sectional area of the sample unit of MPaDue to external objects (load, temperature, etc.) and deformation, in which any section (shear plane) on both sides of the internal forces, known as "internal".Set of internal force, namely, per unit area of the internal force is called the "stress".Stress can be decomposed into component perpendicular to the section (shear plane), known as "asymmetric" or "method to stress";Tangent to section (shear plane) component is called "shear stress.6.Define the hardness of a metal. (b) How is the hardness of a material determined by ahardness testing machine?定义金属的硬度,金属硬度是怎样测试的?When HB > 450 or sample hours, brinell hardness test and will not be used to switch to rockwel l hardness measurement.It is a diamond cone apex Angle 120 ° or 1.59 and 3.18 mm steel ball d iameter, under certain load down into the material surface under test, the hardness of materials b y indentation depth.7.What are the load used in (a) Rockwell B hardness test, and (b) Rockwell C hardness test?8.What is the difference between Vickers and Knoop hardness tests?I n Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.9.Describe the slip mechanism that enables a metal to be plastically deformed withoutfracture.10.Why does slip in metals usually take place on the densest-packed planes?11.Why does slip in metals usually take place in the closest-packed directions?Slip always take place along the atomic density maximum directions (closest-pack ed)and the density on the largest crystal(closest-packed directions),This is due to th e close, close direction between surface spacing between maximum, binding force is wea kest.So the slip plane is the secret of the crystal surface, on the surface of the sliding di rection for the close direction.12.What are the principal slip planes and slip directions for FCC metals? (b) What are theprincipal slip planes and slip directions for BCC metals? (c) What are the principal slip planes and slip directions for HCP metals?13.Describe the deformation twinning process that occurs in some metals when they areplastically deformed.14.What is the difference between the slip and twinning mechanisms of plastic deformation ofmetals?15.What important role does twinning play in the plastic deformation of metalswith regard to deformation of metals by slip?16.Define the critical resolved shear stress for a pure metal single crystal?
