The world art market had already been losing momentum for a while after rising bewilderingly since 2003．At its peak in 2007 it was worth some $ 65 billion, reckons Clare McAndrew, founder of art Economics, a research firm-double the figure five year earlier. Since then it may have come down to $ 50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries. In the weeks and months that followed Mr Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008．Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $ 200m in guarantees to clients who had placed works for sale with them. The current downturn in the art market is the worst since the Japanese stopped buying Impressionist at the end of 1989．This time experts reckon that prices are about 40% down on their peak on average, though some have been far more fluctuant. But Edward Dolman, Christie's chief executive, says: "I'm pretty confident we're at the bottom. " What makes this slump different from the last, he says, is that there are still buyers in the market. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds--death, debt and divorce-still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return. In the first paragraph, Damien Hirst's sale was referred to as "a last victory" because______. A．the art marker had witnessed a succession of victories B．the auctioneer finally got the two pieces at the highest bids C．Beautiful inside My Head Forever won over all masterpieces D．it was successfully made just before the world financial crisis

Few doctors believe any longer that it is simply a question of will power. And for those people that continue to view addicts as merely "weak", recent genetic research may force a rethink. A study conducted by Jacqueline Vink, of the Free University of Amsterdam, used a database called the Netherlands Twin Register to analyze the smoking habits of twins. Her results, published in the Pharmacogenomics Journal, suggest that an individual's degree of nicotine dependence, and even the number of cigarettes he smokes per day, are strongly genetically influenced. The Netherlands Twin Register is a voluntary database that contains details of some 7,000 pairs of adult twins (aged between 15 and 70) and 28,000 pairs of childhood twins. Such databases are prized by geneticists because they allow the comparison of identical twins (who share all their genes) with fraternal twins (who share half). In this case, however, Dr. Vink did not make use of that fact. For her, the database was merely a convenient repository of information. Instead of comparing identical and fraternal twins, she concentrated on the adult fraternal twins, most of whom had completed questionnaires about their habits, including smoking, and 536 of whom had given DNA samples to the register. The human genome is huge. It consists of billions of DNA "letters", some of which can be strung together to make sense (the genes) but many of which have either no function, or an unknown function, To follow what is going on, geneticists rely on markers they have identified within the genome. These are places where the genetic letters may vary between individuals. If a particular variant is routinely associated with a particular physical feature or a behavior. pattern, it suggests that a particular version of a nearby gene is influencing that feature or behavior. Dr. Vink found four markers which seemed to be associated with smoking. They were on chromosomes 3, 6, 10 and 14, suggesting that at least four genes are involved. Dr. Vink hopes that finding genes responsible for nicotine dependence will make it possible to identify the causes of such dependence. That will help to classify smokers better (some are social smokers while others are physically addicted) and thus enable "quitting" programs to be customized. Results such as Dr. Vink's must be interpreted with care. Association studies, as such projects are known, have a disturbing habit of disappearing, as it were, in a puff of smoke when someone tries to replicate them. But if Dr. Vink really has exposed a genetic link with addiction, then Mark Twain's problem may eventually become a thing of the past. Mark Twain is mentioned in the passage in order to show that A．he is a man with very Strong will power. B．it is easy to give up smoking temporarily. C．famous writers are often heavy smokers. D．only few people have his determination.

It is unclear what is behind the phenomenon but it may be that beauty creates confidence. The self-confident may appear to be doing better than they are and will not hesitate about asking for a pay rise. Researcher Jason Fletcher, of Yale University in the U.S., rated the attractiveness of the 4,000 men and women. Just over half were judged average, while 7 percent were felt to be very attractive and 8 percent were judged unattractive or very unattractive. The volunteers also sat an IQ test and reported their salary. It became clear that pay scales were far from fair. For instance, a 14- point increase on the IQ score was associated with a 3 to 6 percent increase in wage. But being of above-average looks increased pay by 5 to 10 percent . For a plain person to be paid the same as a very attractive one , they would have to be 40 percent brighter, the journal Economics Letters reports. Dr Fletcher said:“The results do show that people ’s looks have an impact on their wages and it can be very important.” 6.What is the “plainness penalty ”？ A.To be paid less for being ordinarily-looking B.To be laughed at for being ordinarily-looking C.To be fired for being ordinarily-looking D.To be questioned for being ordinarily-looking How many people were rated as very attractive in Jason Fletcher ’s study？A.About 280 B.About 4,000 C.About 2,000 D.About 320 What ’s the average annual salary of a good-looking person？A.￡2,500 B.￡25,000 C.￡22,500 D.￡27,500 Which of the following best summarizes the main idea of the passage ？A.IQ is less important than appearance B.Confidence makes people prettier C.Good looks earn an extra penny D.How Plain Janes get a higher salary Good-looking people are usually paid more probably because________ .A.they look smarter B.they have higher degrees C.they are better at pleasing others D.they are more confident
