It has done so, in part, by surrendering to Google, the younger Internet company that is its main rival. Yahoo! lives, but on the web's equivalent of life support. Yahoo! 's descent, first gradual then sudden, during this decade marks a surprising reversal of the fates of the only three big Internet firms to have survived since the web's earliest days. Back in 1994, Jerry Yang and David Filo, truant PhD students at Stanford, started to publish a list, eventually named Yahoo!, of links to cool destinations on the nascent web. Around the same time, Jeff Bezos was writing his business plan for a website, soon to be called Amazon, for selling books online. The following year, Pierre Omidyar, a French-born Iranian-American, put an auction site on the web that would become eBay. Even as hundreds of other dotcoms fell by the wayside at the turn of the century, these three made it through the great Internet crisis and have since prospered, to varying degrees and at different times. Their fates have reflected the evolution of the web as a whole, and now suggest its future direction. For many years eBay and Yahoo! made more money than Amazon, which, as a capital-intensive retailer, struggled longer with losses and then made profits at lower margins. And yet, says Pip Coburn of Coburn Ventures, an investment adviser, Yahoo! is now drifting and eBay is a washed-up quasi-monopoly, whereas Amazon finds itself at the Internet's cutting edge. Yahoo! set out to be a new sort of media company. Its site became a tawdry strip mall, with big, flashing advertisements next to users' e-mail inboxes. The firm slipped into a mindset of product silos, with the teams for the home-page, e-mail, finance and sports pages competing with each other and for advertisers, and confusing users. Yahoo! 's bigger mistake was not to see how the web was changing. Google, also founded by two truant Stanford PhD students, became the leader of a new generation with a vision that web search, rather than Yahoo! 's "portal" approach, would guide surfers around the Internet. Yahoo! belatedly tried to keep up and bought sites such as flicker, corn for photo-sharing and del.icio.us.com for bookmark-sharing, but it "put them in the curio cabinet" without transforming the company, say's Jerry Michalski, a technology consultant. EBay took a different route, recognising that its business—in effect, online yard sales—had potential network effects: in short, that sellers and buyers would flock to whichever site already did the most trading. The firm became a de facto monopoly, but with that came a culture that left many of its users disenchanted, and growth slowed. Some measures, such as the number of new listings of items for sale, are even in decline. Buyers and sellers increasingly rely on Google's search model, or online social networks, to find things and one another. EBay's new boss, John Donahoe, is not facing a crisis like Yahoo! 's—but neither does he appear to have a big idea for the future. Amazon, by contrast, has found exactly that. It is the only one of the three that has been led continuously by the same man, its founder Jeff Bezos. Unlike his peers at the other two firms, Mr. Bezos has stuck to his original vision—while adding two new ideas as they presented themselves. His original plan was to become "Earth's biggest fiver" of merchandise, from books and toys to electronics and almost anything else that can be shipped. Then Mr. Bezos realised that the same online store-front and logistics system that worked for Amazon itself could also work for others. So he added an entirely new category of customers: third-party sellers, who account for 30% of all items sold through Amazon's site today. Then, about four years ago, another, and potentially bigger, idea struck Mr. Bezos. Their infrastructure is rivalled in scale by only a few other firms in the world, including Google. So Mr. Bezos again added an entire category of customers: firms that wanted to rent computing capacity from Amazon over the Internet, rather than build their own data centres in a warehouse. It has signed up over 370,000 customers. Almost by accident, Amazon has thus "backed into cloud computing". If there is a leader in the cloud, it is Google. But Amazon is now fight up there. Better yet, although Amazon overlaps with Google in the cloud, it does not rival it directly. Google mostly offers entire applications, such as word processing or spreadsheets, to consumers through their web browsers. Amazon offers services to programmers so they can build and run their own applications. So there they are. Jerry Yang is still boss of Yahoo !, although angry, restive shareholders may oust him at their annual meeting on August 1st, and his top lieutenants are leaving in droves. John Donahoe is looking hard for a purpose that will enable eBay to survive another decade. And Mr. Bezos is right where he wants to be.

填空题A=James Hargrove B=John Joe C=Sergeant Jackson Which black officer... ● staged in the car and radioed for help when seeing a robbery? 1 ● is a son of retired Los Angeles police officer? 2 ● believes that in most cases white and black officers would help each other in case of the danger? 3 ● thinks that the conflicts arising from being" black in blue" can be humiliating? 4 ● said he and the white officers didn"t talk to each other for eight hours when at work? 5 ● thinks that the relationship between black officers and the black community has improved? 6 ● mentioned that black and white officers were partners on the job, but the story was different when they were off duty? 7 ● said that when black officers took off their uniforms, whites would treat them as the ordinary black? 8 ● prefers to work in minority communities? 9 ● mentioned that they were asked to think of themselves as being blue rather than black? 10 James Hargrove He remembers the time he saw a robbery in progress in Manhattan. As a police officer, he wanted to jump out of his patrol car. As a black man in civilian clothes, carry a weapon, he knew better. So Patrolman Hargrove did what most other off-duty black police officers have been trained by instinct and by the job to do in such situations: he stayed in the car and radioed for help. It underscores a more complex issue: how the pervasive stereotype of criminals as young black males may influence police officers" responses. That point was illustrated in December in Prince Georges country, Md., when a black Washington, D. C. police officer was shot and killed in his home by a white country police officer who mistook him for an armed burglar. In an interview, Patrolman Hargrove, who lives in a predominantly black section of the capital, said the conflicts and ambiguities that arise from being "black in blue" can be humiliating and demoralizing. "When the white guys finish work, they go home to their white neighborhoods and the black guys go home to the black community." He continued, "You may be their partner on the job, but the minute you"re off duty, it"s a different story. It"s like you"ll find a bunch of white cops hovering in the locker room snickering at something—then when you walk in they stop. Now what are you supposed to think?" John Joe "I work in a white area on the West Side. Being black, in plain clothes, people might mistake me for a burglar and shoot me. It"s better for me to be in a black area. Very few black officers work in white areas. The majority of the policeman in the station where I work are young whites," said John Joe. In an interview he said, "Most of us believe that regardless of personal likes, dislikes or prejudice, white officers would come to our aid and we would aid them. And we share the view that the relationship between black police officers and the black community, where the black officer is sometimes regarded as a traitor and often shunned, has improved in recent years, in part because of attempts by black police officers to control the high incidence of crime in black neighborhoods." "We"re tied to the black community by this umbilical cord," he continued, "We can"t sever it because we have a commonality, and that is our color. We know that if we take off our uniforms, whites would treat us the same as they do other blacks in Anacostia," a predominantly, low-income black community in the District of Columbia. "On the one hand, we"re asked to think of ourselves as being blue, not black. I had one fellow officer, who was white, tell me that if he calls blacks niggers it shouldn"t offend me because I"m blue, not black." Sergeant Jackson He is 29 years old, a graduate of California Lutheran College and the son of a retired Los Angeles police officer. In an interview, he said, "They give you a different partner about every day. You ride around, patrol the area, answer the phone calls, write tickets—it gets pretty dull. You and the white don"t talk to each other for eight hours." The white guys feel, "I"m with this black to put on a comrade of integration." I am saying to myself, "The only reason I"m with this white cop is to protect his life while he"s riding around in the black community." "We can always feel that we are treated differently from whites in assignments and promotions. We are more likely to be assigned to high crime areas in which minority groups live. I preferred to work in minority communities, even with the greater potential for danger. We serve a dual purpose in the black community in that we are seen as protectors of the community and in some respects as role models. Most of us have learned how to respond to the pressures we face on and off the job, and most also concede that constant stress may eventually begin to take its toll." "Sometimes I feel that it was destroying me as a black man. When I joined the force eight years ago I went along with the racial slurs in order to be accepted by the police fraternity. It began to turn me against my own people. I began to see fellow blacks as untrustworthy, as thieves and criminals. I began to shut myself off from my family and friends."

填空题A= BOOK1 B= BOOK2 C= BOOK3 D= BOOK4 Which book(s) say(s) that... · the climate affects the future sustainable agricultural development? (71) · environmental control is related with the national revenues? (72) · the environmental problems are not caused overnight? (73) · a variety of species are on the decrease? (74) · agriculture is also a factor for the degradation of environment? (75) · pollution can be controlled by increasing the production cost of polluting goods? (76) · pollution control needs the support of technology and techniques? (77) · provides lessons for agriculture, trade, land use and tax policy from an economic perspective? (78) · the degradation of environment causes the change of climate? (79) · the approaches to research should be adjusted to the changing situation? (80) A BOOK 1 The book offers a comprehensive perspective on the consequences and possible policy solutions for climatic change as we move into the twenty-first century. It assesses the impact of potential feature global climate change on agriculture and the need to sustain agricultural growth for the economic development. The book begins by examining the role of international research institutions in overcoming environmental constraints on sustainable agricultural growth and economic development. The authors then discuss how agricultural research systems may be restructured to respond to global environmental problems such as climate change and loss of genetic diversity. The discussion then extends to consider environmental accounting and indexing, to illustrate how environmental quality can be included formally in measures of national income, social welfare and sustainability. The third part of the book focuses on the effects of and policy responses to climate change. Chapters in this part examine the effect of climate change on production, trade, land use patterns and livelihoods. They consider impacts on the distribution of income between developed and developing countries remain a major economic activity. Authors take on an economy-wide perspective to draw lessons for agriculture, trade, land use and tax policy. B BOOK 2 The ozone layer is threatened by chemical emissions; the climate is endangered from fossil and deforestation, and global biodiversity is being lost by reason of thousands of years of habitat conversions. Global environmental problems arise out of the accumulated impacts from many years' and many countries' economic development. In order to address these problems the states of the world must cooperate to manage their development processes together—this is what an international environmental agreement must do. But can the world's countries cooperate successfully to manage global development? How should they manage it? Who should pay for the process, as well as for the underlying problems? This book presents an examination of both the problem and the process underlying international environmental lawmaking: the recognition of international interdependence, the negotiation of international agreements and the evolution of international resource management. It examines the general problem of global resource management by means of general principles and case studies and by looking at how and why specific negotiations and agreements have failed to achieve their targets. The book is designed as an introductory text for those studying global environmental policy making and institution building. It will also be of interest to practitioners and policy makers and scholars in the areas of environmental economics and law. C BOOK 3 Industrialization to achieve economic development has resulted in global environmental degradation. While the impacts of industrial activity on the natural environment are a major concern in developed countries, much less is known about these impacts in developing countries. This source book identifies and quantifies the environmental consequences of industrial growth, and provides policy advice, including the use of clean technologies and environmentally sound production techniques, with special reference to the developing world. The developing world is often seen as having a high percentage of heavily polluting activities within its industrial sector. This, combined with a substantial agriculture sector, which contributes to deforestation, the erosion of the top soil and desertification, has led to extreme pressures on the environment and impoverishes the population by destroying its natural resource base. This crisis suggests that sound industrialization policies are of paramount importance in developing countries' economic development, and calls for the management of natural resources and the adoption of low-waste of environmentally clean technologies. The authors consider the industrial sector as a pollutant to other sectors of the economy, and then focus on some industrial-specific pollutants within the manufacturing sector and some process-specific industrial pollutants. They conclude by reviewing the economic implications of promoting environmentally sound industrial development, specially adressing the question of the conflict or complementarily which may exist between environmental goods and industrial production. D BOOK 4 This is an important book which presents new concepts of the marginal cost of substituting non-pollutive for pollutive goods. Technically in its approach it complements the other literature in the field and will be a significant contribution to the understanding of microeconomic issues in pollution control. The book focuses on the three main concepts: substitutions in consumption, emission abatement and exposure avoidance. The first part considers the adjustment of the scope and combination of goods produced as a method for controlling pollution. The author argues that pollution is controlled by increasing the relative price of the polluting goods in the production process, thereby reducing demand and subsequent production of the goods. In the second part, the discussion is extended to include the possibilities of preventing or abating emissions in relation to three models: first, pollution prevention when non-polluting inputs and processes are substituted for pollutants; second, when a proportion of the polluting output is recycled rather than being discarded; and finally end-of-pipe abatement where additional technology is used. In conclusion, the author assesses the extent to which pollution damage is controlled by avoidance of emissions, with avoidance being modeled as an add-on technology with its own returns to scale.

C. Washington, the capital of the United States, is in Washington D. C. and is situated on the Potomac River between the two states of Maryland and Virginia. The population of the city is about 800,000 and it covers an area of over 69 square miles (including 8 square miles of water surface). The section was named the District of Columbia after Christopher Columbus, who discovered the continent. The city itself was named Washington after George Washington, the first president of U. S. A. The building of the city was accomplished in 1800 and since that year, it has served as the capital of the country. Thomas Jefferson was the first president inaugurated there. In the War of 1812, the Britain army seized the city, burning the White House and many other buildings. Washington is the headquarters of all the branches of the American federal system: Congress, the Supreme Court and the Presidency. Apart from the government buildings, there are also some other places of interest such as the Washington Monument, the Lincoln Memorial, the Jefferson Memorial, the Literary of the Congress and Mt. Vernon, home of George Washington. B New York City New York City, located in New York State, is the largest city and the chief port of the United States. The city of New York has a population of over 7 million (1970) and Metropolitan, 12 million. The city with its good harbor was discovered as early as 1524, and it was established by Dutch who named the city New Amsterdam. In 1664, the city was taken by the English and it got the name New York as it bears now. During the American Revolution in 1776, George Washington had his head-quarters for a time in New York City. The Declaration of Independence was first read there in July 4th, 1776. The city remained the nation's capital until 1790. New York became an important port early in the last century. A large portion of the national exports passed through New York Harbor. New York has become one of the world's busiest ports and also the financial, manufacturing, and travel center of the country. Some of the places of interest in the city are: the State of Liberty (152 meters high) which was given by the French people to the American people as a gift in 1877. It was erected on Liberty Island in the middle of New York Harbor. Broadway, Wall Street and Fifth Avenue are a few of New York's most famous streets. Wall Street, where many famous banks are centered, is the financial center of America and has be come a symbol of the American monopoly capitalism. Fifth Avenue is the street with famous stores and shops. Time Square is in the center of New York City, at Broadway and 42nd Street. Greenwich Village is an art center. Many American artists and writers have lived and worked there. The group of the third largest city buildings of the United Nations stands along the East River at the end of the 42nd Street. C Chicago Chicago, the second largest city in population in the United States, lies on the southwestern shore of the Lake Michigan at a point where the Chicago River enters the lake. The city is now the largest industrial city in the country. Both heavy and light industries are highly developed, particularly the former. Black metallurgical industry and meat processing are assumed to be the head in the U. S. . It is now considered the center of industry, transportation, commerce and finance in the mid-west area. The working class in Chicago has a glorious revolutionary tradition. On May lst, 1886, thousands upon thousands of workers in the city and the country went on strike for the eight-hour workday and succeeded. Since 1890, May 1 st has been observed every year as an International Labor Day. On March 8th, 1909, women workers in Chicago held a big strike for freedom and equal rights with men and since 1910, March 8th has been celebrated each year as an International Working Women's Day. D Los Angeles Los Angeles is situated near the Pacific coast in California. It is an important center of shipping, industry and communication. The city was first founded by a Spanish explorer in 1542 and turned over to the US in 1846. The city leads the country in the manufacture of aircraft and spare parts and the area has become an aviation center. California is a leading state in the production of electronic products and the area of Los Angeles has grown into an important electronic center. Since the first American movie was made in Los Angeles in 1908, the city has remained the film center of the United States. Hollywood, the base of the film industry in the city, is a world famous film producing center.

填空题There is one kind of pain for which nobody has yet devised a cure—the pain that comes from the ending of a relationship. The relationship—it can be a marriage, a love affair, or a deep friendship, in fact, any emotional bond between two people—may have come to an abrupt but premeditated end, or it may have simply fizzled out as people and circumstances change. You may have been the one to break it off, or you may have been on the receiving end a brief phone call, a "Dear John" letter such as soldiers at the front used to dread receiving from their girlfriends back home who had got tired of waiting, or simply a quiet fading away. 1 Although there is no cure for grief, we cannot help looking for one to ease the pain, and help us forget our tears. We seek refuge in other relationships, keep ourselves busy with work, try to immerse ourselves in our hobbies. Perhaps we start to drink a little more than is good for us to "drown our sorrows", or we heed the conventional advice and join a club or society. 2 Moreover, we are always in a hurry to get rid of our grief. It is as if we were ashamed of it, feeling that we should be able to "pull ourselves together", and trying to convince ourselves as we bite on the pillow that we are much too old to be crying. 3 It is not easy to explain why we adopt this attitude to emotional pain, when it would never occur to us to suggest that we ought to overcome physical pain by a simple effort of will power. Part of the answer must lie in the nature of grief itself. When the love affair dies, you cannot believe that you will ever find another to replace the one who has gone so completely out of your life. 4 And yet, grief is like one of those illnesses that must run their course, regardless of what we might do. Memories do fade, a healing skin does start to grow over the wound, the intervals between sudden glimpses of the love you have lost do get longer and longer, and bit by bit, painfully, life resumes its normal flow. Such is the perversity of human nature that we can even start to feel guilty as these things start to happen, as if it were an insult to the lost loved one that we can begin to forget at all. 5 How much time is needed will vary from person to person, but psychiatrists have a rule of thumb: your grief will last as long as the original relationship. The sad thing is that when the breakdown occurs we can only stumble forward over the stones beneath our feet. It is dark ahead and we must be prepared to fall painfully many times on the way before we begin to discern the light at the end of the tunnel. A. Some bury their grief deep inside themselves so that few realize what they are going through; others seek relief by pouring their hearts out to their friends, or to anyone else who is prepared to offer a sympathetic shoulder to lean on. But even our friends after a while start to show their irritation, and suggest with their reproachful glances that it is about time we stopped our crying. They, too, are in a hurry for the thing to be over. B. The future stretches endlessly and bleakly ahead of you: you are utterly alone and without hope of consolation. Even after many, many months, when you think that you have begun to learn to live without your lost love, something—a familiar place, a snatch of music, a whiff of perfume, a casual work—will suddenly bring the bittersweet memories flooding back. You choke back the tears and the desperate, almost angry feeling that you are no better now than the day the affair ended. C. The important thing to admit about grief is that it will take its time. By trying to convince ourselves that it ought to be over sooner, we create an additional tension which can only aggravate the condition. People who have gone through the agony of a broken relationship—and there must be few who have not—agree that time is the great healer. D. The cultivation of a hobby and new forms of interest is therefore a policy of first importance to us. But this is not a business that can be undertaken in a day. The growth of alterative mental interest is a long process. E. Unfortunately, all of these things do little more than alleviate the symptoms without touching the cause of the ailment. F. However it ended and whoever took the initiative to end it, the pain is equally intense and hard to bear. It is a sort of death, and it requires the same period of mourning, the same time for grief.

填空题{{B}} A = Superficial Spreading Melanoma B = Nodular Melanoma C = Lentigo Maligna Melanoma D = Acral Lentiginous Melanoma Which type(s) has/ve the trait that ...{{/B}} Melanoma, also referred to as "malignant melanoma", is the most serious form of skin cancer. It is the skin cancer most likely to spread to lymph nodes and internal organs. There are four most common types of melanoma, which accounts for about 100% of diagnosed cases. {{B}}A{{/B}} {{B}}Superficial Spreading Melanoma:{{/B}} Superficial spreading melanoma (SSM) is the most common type of melanoma in the United States, accounting for about 70% of all diagnosed melanoma cases. This type of melanoma can strike at any age and occurs slightly more often in females than males. SSM is the leading cause of death from cancer in young adults. When SSM occurs in females, it most commonly appears on the legs. In males, it is more likely to develop between the neck and pelvis. However, this does not mean that females do not get SSM on their trunks or that males do not see SSM on their legs. This melanoma can occur anywhere on the skin's surface. A typical SSM lesion has irregular borders and various shades of black, brown, gray, blue, pink, red, or white. Within the lesion there can be a remarkable variation in color involving white, pink, brown, and black. In the early stages, SSM usually appears as a flat spot that looks like a freckle that is spreading sideways on the skin. Over time, the pigmentation in the lesion may darken, and the lesion may grow, develop increasingly irregular borders, and have areas of inflammation within the lesion. The area around the lesion may begin to itch. Occasionally, a SSM may become "less" pigmented as a person's immune responses try to destroy it. Superficial spreading melanoma can progress rapidly. {{B}}B{{/B}} {{B}}Nodular Melanoma:{{/B}} Nodular melanoma (NM) is the most aggressive type of melanoma and accounts for about 15% of all melanomas diagnosed in the United States. It can appear anywhere on the body and occurs more often in males than females. It can develop at any age; however, it is most often seen in people aged 60 and older. NM is different from other types of melanoma. It tends to grow more rapidly in thickness than in diameter and it may not have a readily visible phase of development. Instead of arising from a pre-existing mole, it may appear in a spot where a lesion did not previously exist. Since NM tends to grow deeper more quickly than it does wide and can occur in a spot that did not have a previous lesion, the prognosis is often worse because it takes longer for a person to be aware of the changes. NM is most often darkly pigmented; however, some NM lesions can be light brown or even colorless (non-pigmented). A light-colored or non-pigmented NM lesion may escape detection because the appearance is not alarming. An ulcerated and bleeding lesion is common. {{B}}C{{/B}} {{B}}Lentigo Maligna Melanoma:{{/B}} Lentigo maligna melanoma (LMM) typically occurs on sun-damaged skin in the middle-aged and elderly, especially on the face. This melanoma may be mistaken in its early, and most treatable, stages for a benign "age spot" or "sun spot". LMM accounts for about 10% of the melanomas diagnosed in the United States. Since LMM is so easily mistaken, it can go undetected for years. This can be quite dangerous. LMM begins as a spreading, flat, patch with irregular borders and variable colors of brown. This lesion is called "lentigo rnaligna". This spreading brownish patch may grow slowly for years and is often mistaken for lentigo simplex—a benign (non cancerous) brownish patch that can develop in the elderly after years of sun exposure. As the lesion grows and evolves, both the pigmentation and borders tend to become more irregular. This often occurs slowly over a period of 10 to 15 years. It also can happen rapidly--in a matter of weeks or months. As the lesion grows deeper into the skin (thickness increases), it may become various shades of black and brown. Dark nodules may appear within the irregular borders. These nodules me the invasive tumor, and if large enough to be felt by touch, will feel lumpy. {{B}}D{{/B}} {{B}}Acral Lentiginous Melanoma:{{/B}} In the United States, acral lentiginous melanoma (ALM) accounts for about 5% of all diagnosed melanomas. It also is the most common form of melanoma in Asians and people with dark skin, accounting for 50% of melanomas that occur in people with these skin types. ALM is sometimes referred to as a "hidden melanoma" because these lesions occur on parts of the body not easily examined or not thought necessary to examine. ALM develops on the palms, soles, mucous membranes (such as those that line the mouth, nose, and female genitals), and underneath or near fingernails and toenails. ALM is often overlooked until it is well advanced because in the early stages, it often looks like a bruise or nail streak. As an ALM tumor increases in size, it usually becomes more irregular in shape and color. However, some ALM lesions can be lightly colored or colorless. The surface of the ALM lesion may remain flat, even as the rumor invades deeply into the skin. Thickening ALM on the sole of the foot can make walking painful and be mistaken for a plantar wart.· it is the most common form of melanoma in people of color? 71. ______· this type of melanoma occurs more often in males than females? 72. ______· dark nodules may appear within the irregular borders of the lesions? 73. ______· it may develop on mucous membranes? 74. ______· it can occur anywhere on the skin's surface? 75. ______ 76. ______· this type of melanoma occurs more often in females than males? 77. ______· it often looks like a bruise or nail streak in the early stages? 78. ______· it can develop on sun-damaged skin especially on the face? 79. ______· it looks like a freckle that is spreading sideways on the skin in the early stages? 80. ______

It is still much cheaper than its waterside neighbors. The housing stock is predominately 1980s flats, many arranged in cul-de-sacs(死胡同) and closes around Surrey Quays Road. The unpopular architecture has led to the area being called the Milton Keynes of London but properties are spacious and unfashionable style has kept prices down. Paul Mitchell, of estate agents Alex Neil, says, "There is precious little period property, but you will get far more for your money here than a Victorian house with lots of original features down the road in Bermondsey. " Surry Quays shopping center provides all the amenities of a high street but the area is lacking in fun. However, Southwark Council is in talks to develop the "night time economy" which could well lead to an increase in bars and restaurants to cater for the growing number of young professional residents. "It is possible to get a good three-bedroom house in Rotherhithe for 280000," says Wumine Jordan Robinson, of agents Burwood Marsh. "About eight minutes' walk from the Jubilee Line which will have you in Bond Street in 15 minutes. There are not that many areas in London where that is possible." B Barnes Barnes sits just across the river from Hammersmith in southwest London, but it could not be more different from the noise and bustle of the opposite bank. It has been called one of the last true London "villages" with happy residents keeping its old school charms quiet from nosey outsiders and potential developers. Being by the river and predominately residential gives Barnes an attractively lazy vibe. It has a traditional village green complete with idyllic duck pond and quaint pub. The high street is about as far from the Pound Shop and Primark ambience of its neighbors as is possible. But buying into Barnes is not cheap. "Family houses are snapped up incredibly quickly," claims Chris Carney, sales negotiator at Boileaus estate agents. "It is very hard to get properties of this size, with outside space so close to London, which is why they are expensive." Large detached Victorian houses on the two main roads, Casttenau and Lonsdale, normally have between five and seven bedrooms, gardens of 120 ft and off-street parking. These sell for anything between ￡2 million and ￡5 million. By the village green there are rows of immaculate terraced houses on a number of streets that run off Church and Station roads, and four-bedroom houses of this kind sell for around ￡1 million. C Willesden Green Willesden Green has both suffered and benefited from its famous neighbors. Despite its growing popularity, the area remains interesting and multi-cultural, injecting a little bit of soul into what could otherwise become just another yuppie backwater. "Willesden Green has a diverse range of properties from 1930s semi-detached houses to large Victorian properties and new-builds which attract all kinds of buyers," says Richard Chiti, sales manager at estate agents Ellis ＆ Co. "The roads bordering West Hampstead are popular, as they are wide, tree-lined streets with sizeable family houses. Properties in and around Dobree Road, which lead down to Kensal Rise, are also in high demand." Estate agents and residents agree that the area used to be regarded as dangerous and undesirable, but this has changed over the last decade. It's popular because it is still affordable, although prices have rocketed over the last year. D King's Cross King's Cross used to be renowned for problems including drugs, prostitution and street crime but a ￡2 billion regeneration programme should help the area lose its seedy reputation. The project includes a new Eurostar terminal opening this year and a spruced-up tube station, alongside hundreds of new homes, offices and leisure facilities set to be completed in 2015. Such development has had a predictable effect on house prices. "There are a lot more amenities now, such as supermarkets, cafes and bars, and the issue people used to have with safety a few years ago has disappeared. " By the canal basin, new-built flats and luxury warehouse conversions from the bulk of property, and at the top end of the market there are stunning penthouses available with views across London. Much of the new development is centered on the back of the station, off York way, and flats are being sold to eager buyers off plan. The older properties are mainly mid-Victorian terraces around Caledonian Road and the streets heading towards Angel, and ex-local authority blocks where it is possible to pick up a two-bedroom refurnished flat for under ￡250000. Smith adds, "Investment-wise, King's Cross is a good bet. There is a big rental market here and prices will go up. There are still cheaper properties available, one- to two-bedroom flats in Victorian conversions, or ex-council properties. But people are holding on to them for dear life in the hope they will go up in value. If you find one, it is worth investing in./

填空题{{B}} A ＝ REPORT 1 B ＝ REPORT 2 C ＝ REPORT 3 D ＝ REPORT 4 Which report(s) say(s) that:{{/B}} {{B}} A Report 1{{/B}} A new study requested by the U. S. Congress is helping clear up some of the controversies regarding global warming. It finds the warming of the northern hemisphere in the last decades of the 20th century was unprecedented in the past thousand years. It also says the decade of the 1990s was the warmest on record. Authors believe human activities are at least partly responsible for recent warming. The study comes as extreme weather has shuck many parts of the United States. There was flooding in parts of the Midwest last week, more heavy rains this week in the southern and eastern United States. Scientists say that the warmer the air, the more evaporated water it holds. Winds pick up more moisture from the hotter ocean surfaces, resulting in heavier and more frequent downpours. Recent data compiled on wildfires indicate an increasing frequency in North America and elsewhere around the world. Scientists say generally over the last five decades snows are melting sooner and faster, producing hot, dry drought conditions in many parts of the world. Weather patterns have natural cycles, but this latest study suggests more frequent extremes of too dry and too wet conditions may exist for the rest of the decade and beyond.{{B}} B Report 2{{/B}} Scientists observed the highest air pollution on record above the Arctic Circle in May. Air pollution has been linked to a number of medical problems including heart attacks, asthma and stroke. It is so hot in many parts of the U. S. that officials are cautioning people to stay indoors. Even short exposure to high temperatures can cause serious health problems. Heat is not the only danger factor. Hot weather with little or no wind can lead to high levels of air pollution, especially ozone. Last year researchers in Boston analyzed pollution rates in nine major U. S. cities. They found the risk of stroke was one percent higher on days with relatively higher air pollution. Scientists say while this increase may seem small, it has a huge effect, since the number of people living in pollution-prone cities is so great. Researchers say pollution particles in the air may enter the body through the lungs and irritate the walls of blood vessels, encouraging clots that travel to the brain. The Hopkins scientists found these fine particles can reach the small airways and the air sacks in the lungs. A study found a link between fine particles in air pollution and risk of death. It also found that reducing exposure to air pollution decreased the number of deaths associated with pollution.{{B}} C Report 3{{/B}} Europe is baking under a heat wave that has sent temperatures soaring past 36 degrees Celsius in some places. The sizzling weather is blamed for the deaths of at least half a dozen people. Temperatures in parts of France were expected to soar as high as 36 degrees celsius Wednesday. Other parts of Europe are expected to be even hotter. So far, the heat wave has killed at least six people around Europe, including three in France. The heat is accompanied by unusually dry weather in many places. The sizzling scenario seems eerily similar to the heat wave of 2003, when heat was linked to the deaths of roughly 30,000 people around Europe, half of them in France. Things are different this summer. French social workers and ordinary French are checking in on older people, to make sure they're OK. The government has established a weather warning system, and a help hot line for the elderly and other fragile people. Other European countries are taking similar preventative measures. Nobody wants a repeat of the killer heat wave of 2003.{{B}} D Report 4{{/B}} Eleven days of triple digit temperatures in California are taking a toll on the state agricultural industry. Meteorologists expect the deadly heat wave that has killed at least 60 people could subside by this weekend. But the relief may be too late for many California farmers. California dairy farmer Hank Van Exel is doing his best to keep his herds comfortable. But the effect of the heat on his dairy cows is evident. He has lost 14 cows and says milk production is down more than 20 percent. The heat has led to emergency declarations in several counties. The heat has been unprecedented. It's been oppressively hot at night. All of these factors coming together have made it very challenging for the local community. "And California's $ 50-billion a year dairy industry is not the only victim. In vineyard, the scorching temperatures will affect the taste of the wines and grapes are beyond raisin. Over in the tomato fields, the heat has killed about 15 percent of the blossoms that typically yield 46,000 tons of tomatoes per season. People obviously losing money as the days continue to be hot. It's a story repeated in peach orchards and walnut groves and melon patches up and down the state. It's too early to assess total damages but consumers will feel the heat in their pocketbooks.

填空题No matter what your situation is, one of the greatest dangers now is that you'll stop doing what you're already doing right. 66. ______ The first fundamental is maintaining a clear-eyed view of reality, no matter how unpleasantly it may differ from what you expected. It's amazing how many executives are driven by management fads and slogans, big hairy audacious goals (BHAGs), quantum leaps, inspirational leadership--and then refuse to deviate from course even when the environment changes dramatically. 67. ______ As the economy slows, you need to wipe your whiteboard clean and rethink your strategy based on what's realistically achievable. We know of a major chemical company that in the recent era of super growth declared a goal of growing ten times bigger in ten years. It' s a wonderful aspiration, but it shouldn't be the company's focus now. 68. ______ The second fundamental--like the others, it must be non--is to focus on the quality of your people. We hope it' s no longer necessary to argue that this is increasingly your company' s only source of competitive advantage. Yet when times get tough, many companies ease up on recruiting, figuring a slow economy will drive more applicants their way, and they spend less on training as a way to raise profits quickly without doing immediate damage to the business. That's just dumb, people do become obsolete~ they also grow. To put it in old economy terms, can you imagine postponing maintenance on an aircraft for six months? You wouldn't consider it, yet you may be tempted to do something even worse. Successful companies avoid this mistake. 69. ______ The third fundamental is continual, day by day insistence on improving productivity. In a slowdown, productivity typically tanks, leading some people to conclude that it is an unavoidable fact of life. It isn' t, and improving productivity during a downturn puts a company in a stronger competitive position when things turn up. 70. ______ Maintaining a commitment to reality, a focus on people, and rising productivity--assuming you can keep those three plate spinning, you' ll want to make several other moves quickly. (No one said this was easy. ) Speed is the key. Most companies will make most of these eventually, when they' re forced to. Your challenge is to make them first. A. Indeed, researchers have found that when the pressure is on, people exhibit a dismaying tendency to focus on insignificant problems while their perceptions become distorted and they insist on proving that their mistaken view of the situation is actually correct. B. Colgate Palmolive has a remarkable record of improving productivity, as reflected in gross margin, virtually every year for the past ]5 years, even during the last recession. In the brutally competitive slow growing business of household products. Colgate' s stock has risen an average of 28% annually over the past five years. C. This company, like most, should be asking how it' s going to be No. 1 in a new environment. The winning strategies and tactics will not be the same as those for growing tenfold in ten years. All managers will have to be prepared for more frequent shifts in priorities, not just at their own companies but also with customers and supply chain partners. D. Based on our long experience--as a consultant working with some of America' s most important companies and as a journalist investigating them---we're confident that as the economy slows, you' 11 be tempted to forget three of the most important fundamentals for keeping any business successful. This is the time when it's most crucial not to forget them. E.We need to acknowledge when we haven't done things as well as we would like or when we do something wrong, but getting things wrong does not make us useless people. That does not mean we should not face up to our deficiencies, but facing up means moving forward, not allowing in the past. F.The most valuable airline in the world, Southwest, is one of America's most desirable employers and in 1999 received 170, 000 applications for just 6, 000 positions. Yet the company recruits vigorously and never lets up, nor does it get stingy on training. The story is similar at Trilogy, General Electric, McKinley--getting the best people and malting them better is in the DNA of the most successful companies.

填空题A = Benjamin Franklin B = Washington Irving C = James Fenimore Cooper D = Philip Freneau Who... ※ is the first important writer to be critical of his country. 72. ______ ※ advocated old beliefs in some eases. 73. ______ ※ lived 76 years. 74. ______ ※ unfolded an epic account of a frontiersman in his novels. 75. ______ ※ is remembered more for his poetry than his prose. 76. ______ ※ uses many long words, often from Latin, in his book. 77. ______ was once a sailor. 78. ______ ※ wrote a novel in 1826 as the second in the series. 79. ______ ※ got the idea for his most famous story from a German 80. ______ legend. ※ in his short stories, the incidents anti descriptive details 81. ______ usually have symbolic significance. Benjamin Franklin Franklin(1706-1790) was a universal genius who did not realize that his Autobiography would eventually become a classic of its kind. The part of it given here shows the beginnings of his personal, civic, anti political success, yet the account is uncolored by vanity. Franklin shows us that he is a human being as well as a successful man. Though his style of writing was clear anti even plain in his time, we now find it a bit hard to read. It has many long words, often from the Latin language, anti long sentences. But we must remember that he was writing two centuries ago. It is true that Franklin's style is formal. The organization of much of what he says if not how he says it is informal, however. In his famous Autobiography, in particular, he talks first about one thing and then another with little attempt at connecting them. Of course, not all of his ideas were new. In some cases he simply became the most prominent advocate of old ones, especially the beliefs that we should work hard and that we should save our money. These principles had been current since Puritan times but Franklin spread them widely by putting them into a popular almanac or calendar called Poor Richard's Almanac, which he himself printed. Washington Irving Irving (1783—1859) was America's first man of letters, devoting much of Iris career to literature. In his short stories, he usually starts with standard characters-the lazy husbands, for instance, and the termagant wife. He is able, however, in his better stories to place them in a home-like situation and in surroundings that give the stories a kind of vitality. Irving's choice of incidents and descriptive details adds a note of symbolism to the basic themes, creating an almost Gothic atmosphere. Irving got the idea for his most famous story, "Rip Van Winkle," from a German legend about a sleeping emperor, which he points out in a mock-scholarly note added at the end of the story. According to the note, the tale originated with Diedrich Knickerbocker, an old Dutch gentleman of New York, who is really a fictional character created by Irving. (The old gentleman's name was later adopted by a group of New York writers of the period, among whom Irving, James Fenimore Cooper, and William Cullen Bryant were the foremost Knickerbockers.) "Rip Van Winkle" is found in Irving's longer work, The Sketch Book of Geoffrey Crayon, Gent. , published serially in the United States from 1819 to 1820.James Fenimore Cooper Cooper (1789—1851 ) wrote both novels and social criticism. It is his fiction which has become famous, but it is worth remembering that he also wrote books criticizing the shortcomings of democracy in his own country. He is the first important writer to be critical of the United States but he will by no means be the last. His fiction is much more memorable, however. The Last of the Mohicans, written in 1826, is the second novel in Cooper's Leatherstocking Series. Consisting of five novels, the series gets it title from one of the names applied to its frontiersman hero, Natty Bumppo, who is also called Deerslayer, Hawkeye, Pathfinder, and l,eatherstocking. Tile five novels tell the story of Bumppo from youth to old age. The creation of the character of Natty Bumppo is probably the most significant thing that happened in American literature during the first 50 years of its history. Like Sir Walter Scott and other romantic writers who dealt with historical or legendary characters, Cooper, in his tales about Bumppo, unfolded an epic account. Bumppo, a frontiersman whose actions were shaped by the forest in which he lived, seems to be related in some way to the deepest meaning of the American experience itself. Philip Freneau PHILIP FRENEAU was an ardent patriot who is still remembered as the "Poet of the American Revolution." While in college, he had already determined to become a poet. After his experience as a sailor in the Revolutionary War, he turned to newspaper and pamphlet writing. Today, however, Freneau is remembered more for is poetry than his prose. Two of his poems are reprinted below. The first, "The Wild Honey Suckle" was virtually unread in the poet's lifetime, yet it deserves a place among major English and American works of poetry of that time. Much of the beauty of the poem lies in the sounds of the words and the effects created through changes in rhythm. The idea for the second poem, "The Indian Burying Ground, "was suggested by the fact that some Indian tribes buried their dead in a sitting, instead of a lying position. This poem, too, is marked by a regularity of rhythm and meter and by the use of "Reason" as an abstraction which is personified.
