单选题{{B}}Text 2{{/B}} An industrial society, especially one as centralized and concentrated as that of Britain, is heavily dependent on certain essential services: for instance, electricity supply, water, rail and road transport, and harbors. The area of dependency has widened to include removing rubbish, hospital and ambulance services, and, as the economy develops, central computer and information services as well. If any of these services ceases to operate, the whole economic system is in danger. It is this economic interdependency of the economic system which makes the power of trade unions such an important issue. Single trade unions have the ability to cut off many countries' economic blood supply. This can happen more easily in Britain than in some other countries, in part because the labor force is highly organized. About 55 percent of British workers belong to unions, compared to under a quarter in the United States. For historical reasons, Britain's unions have tended to develop along trade and occupational lines, rather than on an industry-by-industry basis, which makes a wages policy, democracy in industry and the improvement of procedure for fixing wage levels difficult to achieve. There are considerable strains and tensions in the trade union movement, some of them arising from their outdated and inefficient structure. Some unions have lost many members because of their industrial changes. Others are involved in arguments about who should represent workers in new trades. Unions for skilled trades are separate from general unions, which mean that different levels of wages for certain jobs are often a source of bad feeling between unions. In traditional trades which are being pushed out of existence by advancing technologies, unions can fight for their members' disappointing jobs to the point where the jobs of other union members are threatened or destroyed. The printing of newspapers both in the United States and in Britain has frequently been halted by the efforts of printers to hold on to their traditional highly-paid jobs. Trade unions have problems of internal communication just as managers in companies do, problems which multiply in very large unions or in those which bring workers in very different industries together into a single general union. Some trade union officials have to be re-elected regularly; others are elected, or even appointed, for life. Trade union officials have to work with a system of "shop stewards" in many unions, "shop stewards" being workers elected by other workers as their representatives at factory or works level.

单选题Despite the fact that comets are probably the most numerous astronomical bodies in the solar system aside from small meteor fragments and the asteroids, they are largely a mystery. Scientists do not know exactly what comets are or where they come from. Educated guesses are the best we have in hand. Considering the role of comets in legend and the memory of man, it is remarkable that we still know so little, relatively, about them. The most famous comet of all, Halley's Comet ( named for the man who predicted its return), was first sighted by the Chinese in 240 B．C．, and it has returned to terrify the people of the world on a regular basis every since then. The ancient considered it an object of ill omen. By mysterious coincidence, the arrival of Halley's Comet coincided with such events as the battle of Hastings in 1066, the Jewish revolt of 66 A．D．, and the last battle of Attila the Hun against the Romans. Nor is it the only comet to fill man with awe, but merely the most famous in a rich aristocracy of blood-freezers. Comets are even more fascinating to amateur astronomers than to professionals, because this is one area where amateurs can make major discoveries. Comet Ikeya Seki, one of the brightest comets to appear in this century was discovered in 1965 by a pair of Japanese amateurs, Ikeya and Seki. The person who discovers a new comet gets his (or her) name put on it. And amateurs have a head start in the race to discover new comets; the shorter focal lengths on their smaller telescopes give them a positive advantage over the huge telescopes such as Mount Wilson which is built to scan for galaxies, not comparatively short distances. Most scientists tend to agree with astronomer Fred T. Whipple that a comet is really a large mushy snowball of frozen ices and gases ( ammonia, methane, possibly carbon dioxide) with a few bits of solid particles stuck inside. But no one is sure how comets are created in the first place. Scientist believe that comets don't exhibit their characteristic tail while they lurk fat out in space away from the warmth of the sun but, rather, wander in the form of frozen lumps, like icebergs. This is the core of the comets. Only when the comet approaches the heat of the sun, does the ice begin to melt and stream away in the form of visible gases. The tails of the comets stream out behind for, literally, astronomical distances. Halley Comet had a tail of 94 million miles long when it visited here in 1910．The Great Comet of 1843 had a tail of 186 million miles long.

单选题With a series of well-timed deals, private-equity firms are giving traditional media- managers cause to be envious. The Warner Music transaction, in which Edgar Bronfman junior and three private-equity firms paid Time Warner ＄ 2.6 billion for the unit in 2003, is already judged a financial triumph for the buyers. Their success is likely to draw still more private -equity into the industry. And the investments are likely to get bigger: individual private- equity funds are growing—a ＄10 billion fund is likely this year—so even the biggest media firms could come within range, especially if private-equity investors club together. Some private-equity firms have long put money in media assets, but mostly reliable, relatively obscure businesses with stable cash flows. Now, some of them are placing big strategic bets on the more volatile bits, such as music and movies. And they are currently far more confident than the media old guard that the advertising cycle is about to turn sharply up- wards. One reason why private-equity is making its presence felt in media is that it has a lot of money to invest. Other industries are feeling its weight too. But private-equity's buying spree (狂购乱买) reveals a lot about the media business in particular. Media conglomerates (联合公司) lack the confidence to make big acquisitions, after the last wave of deals went wrong. Executives at Time Warner, for instance, which disastrously merged with AOL in 2000, wanted to buy MGM, a movie studio, but the board (it is said) were too nervous. Instead, private-equity firms combined with Sony, a consumer-electronics giant, to buy MGM late last year. Private-equity's interest also reflects the fact that revenue growth in media businesses such as broadcast TV and radio is now hard to come by. The average annual growth rate for 12 categories of established American media businesses in 1998-2003, excluding the internet, was just 3.4%, says Veronis Suhler Stevenson, an investment bank. Private-equity puts a higher value on low-growth, high cashflow assets than the public stockmarket, says Jonathan Nelson, founder of Providence Equity Partners, a media-focused private-equity firm. What private-equity men now bring to the media business, they like to think, is financial discipline plus an enthusiastic attitude towards new technology. Old-style media managers, claim the newcomers, are still in denial about how technology is transforming their industry. Traditional media managers grudgingly agree that, so far, private-equity investors are doing very nicely indeed from their entertainment deals. The buyers of Warner Music have already got back most of their $ 2.6 billion from the firm by cutting costs, issuing debt and making special payouts to shareholders. This year, its investors are expected to launch an initial public offering, which could bring them hundreds of millions more.

单选题It is not just Indian software and "business-process outsourcing" firms that are benefiting from the rise of the internet. Indian modern art is also on an upward spiral, driven by the aspirations of newly rich Indians, especially those living abroad, who use the internet to spot paintings and track prices at hundreds of gallery and auction websites. Prices have risen around 20-fold since 2000, particularly for prized names such as Tyeb Mehta and F. N. Souza. There would have been "no chance" of that happening so fast without the internet, says Arun Vadehra, who runs a gallery in Delhi and is an adviser to Christie's, an international auction house. He expects worldwide sales of Indian art, worth $200million last year, to double in 2006. It is still a tiny fraction of the $ 30 billion global art market, but is sizeable for an emerging market. For newly rich often very rich-non-resident Indians, expensive art is a badge of success in a foreign land. "Who you are, and what you have, are on your walls," says Lavesh Jagasia, an art dealer in Mumbai. Indian art may also beat other forms of investment. A painting by Mr. Mehta that fetched $1.58million last September would have gone for little more than $100,000 just four years ago. And a $22million art-investment fund launched in July by Osian's, a big Indian auction house, has grown by 4.1 work by younger artists such as Surendran Nair and Shibu Natesan beat estimates by more than 70%. Sotheby's and Christie's have auctions in New York next week, each with a Tyeb Mehta that is expected to fetch more than $1 million. The real question is tee fate of other works, including some by Mr. Souza with estimates of up to $600,000. If they do well, it will demonstrate that there is strong demand and will pull up prices across the board. This looks like a market with a long way to run.

单选题{{B}}Text 2{{/B}} The biggest danger facing the global airline industry is not the effects of terrorism, war, SARS and economic downturn. It is that these blows, which have helped ground three national flag carriers and force two American airlines into bankruptcy, will divert attention from the inherent weaknesses of aviation, which they have exacerbated. As in the crisis that attended the first Gulf War, many airlines hope that traffic will soon bounce back, and a few catastrophic years will be followed by fuller planes, happier passengers and a return to profitability. Yet the industry's problems are deeper--and older--than the trauma of the past two years implies. As the centenary of the first powered flight approaches in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carriers and another 500-plus domestic ones. The world's biggest carrier, American Airlines, has barely 7% of the global market, whereas the world's biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world's automobile market. Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else, governments dictate who flies under what rules. These aim to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership impede cross-border airline mergers. In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Paris, or Lufthansa offering transatlantic flights from London's Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways. In airlines, the optimists are those who think that things are now so had that the industry has no option but to evolve. Frederick Reid, president of Delta Air Lines, said earlier this year that events since the September 11th attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after five years of accelerated development?
