in criticism or appreciation of the arts have been to 【1】______
to deny the existence of any valid criteria and to
make the words "good" or "bad" irrelevant,
immaterial, and inapplicable. There is no such a
thing, we are told, like a set of standards first 【2】______
acquired through experience and knowledge and
late imposed on the subject under discussion. This 【3】______
has been a popular approach, for it relieves the critic
of the responsibility of judgment and the public by the 【4】______
necessity of knowledge. It pleases those resentful of
disciplines, it flatters the empty-minded by calling
him open-minded, it comforts the confused. Under 【5】______
the banner of democracy and the kind of quality
which our forefathers did not mean, it says, in effect,
"Who are you to tell us what is good or bad?" This
is same cry used so long and so effectively by the 【6】______
the producers of mass media who insist that it is the
public, not they, who decide what it wants to hear and 【7】______
to see, and that for a critic to say that this program is
bad and that program is good is pure a reflection of 【8】______
personal taste. Nobody recently bas expressed this
philosophy most succinctly than Dr. Frank Stanton , 【9】______
the highly intelligent president of CBS television. At
a hearing before the Federal Communications
Commission, this phrase escaped from him under 【10】______
questioning: "One man's mediocrity is another
man's goed program".

Prada claims a new Web site is "under development." But having a mysteriously useless home page, it admits, has an allure. It screams exclusivity: you can see, but you can't click. It's a uniquely Prada solution to this riddle: how to make your luxury brand work on the Internet without diminishing its value. In a sense, the Internet is antithetical to the "high touch" luxury experience. There is no indulgence by sales staff, and customers have come to see the Net as a path to cheap prices, not top-dollar goods. There's no velvet rope: anyone can place an order, or set up shop. That's why Prada strives to maintain the link between its name and the extravagant experience of shopping at stores like its $40 million New York flagship, designed by Rem Koolhaas.
Unlike Prada, most luxury companies can't afford to ignore the Web: in the United States, ecommerce accounted for $2.5 billion in luxury sales. That figure is expected to grow to $7 billion by 2010, says Forrester Research. It's still a small fraction of the total market compared to other retail sectors, but five years ago analysts said there was "no way" luxury would sell online. They were betting customers wouldn't pay that much on the Web, and top brands wouldn't go slumming in this bargain basement. One of the first high-end luxury retailers, Ashford. com, had many well-publicized struggles, with its stock dropping to near rock bottom in 2001.
Companies like Neiman Marcus that have strong catalog sales have made the transition to the Web more easily; online sales are the company's fastest-growing source of revenue. Swiss watchmakers Breitling and Patek Philippe have taken another tack with Web sites that offer only information, not sales. Breitling director of marketing Ben Balmer says a luxury brand needs to offer "a buying experience" that only a well-run store can provide. However, he notes that since 2002, it has presented 30 percent fewer catalogs in the United States, and seen sales rise more than 35 percent, thanks to exposure on the Internet. Prada may not need a working Web site after all.
In the first paragraph, the internet of Prada is mentioned to
A．stress the importance of Web Site.
B．emphasize the peculiarity of Prada.
C．introduce the topic of online sale.
D．solve the doubt of Nina Dietzel.

It is my pleasure to address you as a United Nations Goodwill Ambassador to this Second WorldAssembly on Ageing, an honour which I truly welcome, and one which has provided me with an excellentopportunity to promote awareness of ageing. I congratulate the Secretary-General of the United Nations, thechairmen and the executive heads of the organizations of the United Nations system on their excellent work,the Chairman and Vice-Chairmen of the Preparatory Committee on their dedication, and the many individualswho have helped to make this Second World Assembly possible. [TONE]∥[TONE]
We are honoured to be hosting this world event in Spain. Our interest stems from our realization thatthe ageing of the population presents a challenge for which we must prepare ourselves and that we must beready to take advantage of the abilities of older persons. Therefore, in offering to be the host country, Spainwished to demonstrate its interest in policies for the integration of older persons and to give impetus to aninnovative debate in our society. [TONE]∥[TONE]
We are living through a period of major demographic change. The elderly are ever more numerous.That people are living longer and under better conditions, as a result of social progress, is one of humanity'sgreatest achievements. Older persons are a universal force with the potential to transform. the future. Thisglobal transformation is going to affect individuals, families, communities and virtually every area of society.[TONE]∥[TONE]
Accordingly, we must prepare ourselves for this new challenge by promoting changes in attitude towardsthis demographic revolution, which is taking place because of the increase in the number of older personsin the world. Achieving a society for all ages involves analysing society from a broader perspective andhighlights the role played by relations between the various generations making up society. Solidarity betweenthe generations in all areas of family, community and national life is essential for social cohesion. [TONE]∥[TONE]
We younger people must be increasingly aware that, in order to move forward in building a more just society, we must recognize the advances made by older generations and value their experience and currentabilities appropriately. At the same time, we must be able to transmit such values to coming generations.Inter-generational solidarity is a natural setting within which encounter, learning and exchange take placeamong individuals. It offers advantages to all and helps in achieving a more integrated society. [TONE]∥[TONE]
Together we will build a positive image of ageing, which should involve not simply prolonging life, but also ensuring that old age is healthy, independent, active and fully integrated in society. Ageing should be seen as astage in life during which men and women can still develop their skills, as active agents in our societies, in whichthey should continue to participate as full citizens with full social recognition. [TONE]∥[TONE]
I hope that all the proposals that result from this World Assembly will enable our society to face the challenges posed by the ageing of the population, and that they will be translated into practice by the greatestpossible number of countries in such a way that older persons will benefit from them as soon as possible.
Thank you. [TONE]∥[TONE]
第6题
Five years ago, Europe's aircraft industry needed only 8,000 tonnes of aluminium plate a year for its products. Last year the figure reached 21,800 tonnes. By 2004 it should total 30,000 tonnes. Each airliner contains 180 tonnes of it. That is why the plant is being rebuilt to increase both the quality and the amount of its product.
Aluminium is alloyed with other metals and cast into ingots, and the surface of the ingots is smoothed off. After pre-heating, it is rolled in a mill that can take 3.75-m-wide slabs. The new equipment can make the process more efficient and can produce a better product. For example, computers control the temperature of the hot plates, the rate at which they pass through the mill, the speed of cooling it with water, and so on.
The new plant can handle twice the throughput of the one that it is replacing, thanks to the completely automated and computerized process.
