1、雅思阅读实战16篇（附答案）How to increase salesPublished online: Nov 9th 2006From The Economist print editionHow shops can exploit peoples herd mentality to increase sales1. A TRIP to the supermarket may not seem like an exercise in psychological warfarebut it is. Shopkeepers know that filling a store with the
2、aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is, h
3、ow ants, bees or any social animal, including humans, behave in a crowd) can be used to influence what people buy.2. At a recent conference on the simulation of adaptive behaviour in Rome, Zeeshan-ul-hassan Usmani, a computer scientist from the Florida Institute of Technology, described a new way to
4、 increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted: for instance, by placing everyday items such as milk and eggs at the back of the store, forcing shoppers to walk past other tempting goods to reach them. Mr Usmani
5、and Ronaldo Menezes, also of the Florida Institute of Technology, set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that, if a certain product is seen to be popular, shoppers are likely to choose it too. The challenge is to keep customers informed about what o
6、thers are buying.3. Enter smart-cart technology. In Mr Usmanis supermarket every product has a radio frequency identification tag, a sort of barcode that uses radio waves to transmit information, and every trolley has a scanner that reads this information and relays it to a central computer. As a cu
7、stomer walks past a shelf of goods, a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high, he is more likely to select it too.4. Mr Usmanis “swarm-moves” model appeals to supermarkets because it increases sales without the ne
8、ed to give people discounts. And it gives shoppers the satisfaction of knowing that they bought the “right” productthat is, the one everyone else bought. The model has not yet been tested widely in the real world, mainly because radio frequency identification technology is new and has only been inst
9、alled experimentally in some supermarkets. But Mr Usmani says that both Wal-Mart in America and Tesco in Britain are interested in his work, and testing will get under way in the spring. 5. Another recent study on the power of social influence indicates that sales could, indeed, be boosted in this w
10、ay. Matthew Salganik of Columbia University in New York and his colleagues have described creating an artificial music market in which some 14,000 people downloaded previously unknown songs. The researchers found that when people could see the songs ranked by how many times they had been downloaded,
11、 they followed the crowd. When the songs were not ordered by rank, but the number of times they had been downloaded was displayed, the effect of social influence was still there but was less pronounced. People thus follow the herd when it is easy for them to do so.6. In Japan a chain of convenience
12、shops called RanKing RanQueen has been ordering its products according to sales data from department stores and research companies. The shops sell only the most popular items in each product category, and the rankings are updated weekly. Icosystem, a company in Cambridge, Massachusetts, also aims to
13、 exploit knowledge of social networking to improve sales.7. And the psychology that works in physical stores is just as potent on the internet. Online retailers such as Amazon are adept at telling shoppers which products are popular with like-minded consumers. Even in the privacy of your home, you c

27、：Even in the privacy of your home, you can still be part of the swarm. home应该算是everyday life的一部分） Rogue theory of smell gets a boostPublished online: 6 December 2006 Rogue theory of smell gets a boost1. A controversial theory of how we smell, which claims that our fine sense of odour depends on quan
28、tum mechanics, has been given the thumbs up by a team of physicists.2. Calculations by researchers at University College London (UCL) show that the idea that we smell odour molecules by sensing their molecular vibrations makes sense in terms of the physics involved.3. Thats still some way from provi
29、ng that the theory, proposed in the mid-1990s by biophysicist Luca Turin, is correct. But it should make other scientists take the idea more seriously.4. This is a big step forward, says Turin, who has now set up his own perfume company Flexitral in Virginia. He says that since he published his theo
30、ry, it has been ignored rather than criticized.5. Most scientists have assumed that our sense of smell depends on receptors in the nose detecting the shape of incoming molecules, which triggers a signal to the brain. This molecular lock and key process is thought to lie behind a wide range of the bo
31、dys detection systems: it is how some parts of the immune system recognise invaders, for example, and how the tongue recognizes some tastes.6. But Turin argued that smell doesnt seem to fit this picture very well. Molecules that look almost identical can smell very different such as alcohols, which
32、smell like spirits, and thiols, which smell like rotten eggs. And molecules with very different structures can smell similar. Most strikingly, some molecules can smell different to animals, if not necessarily to humans simply because they contain different isotopes (atoms that are chemically identic
33、al but have a different mass).7. Turins explanation for these smelly facts invokes the idea that the smell signal in olfactory receptor proteins is triggered not by an odour molecules shape, but by its vibrations, which can enourage an electron to jump between two parts of the receptor in a quantum-
34、mechanical process called tunnelling. This electron movement could initiate the smell signal being sent to the brain.8. This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier. Turins mechanism, says Marshall Stoneham of the UCL team, is
35、more like swipe-card identification than a key fitting a lock.9. Vibration-assisted electron tunnelling can undoubtedly occur it is used in an experimental technique for measuring molecular vibrations. The question is whether this is possible in the nose, says Stonehams colleague, Andrew Horsfield.1
36、0. Stoneham says that when he first heard about Turins idea, while Turin was himself based at UCL, I didnt believe it. But, he adds, because it was an interesting idea, I thought I should prove it couldnt work. I did some simple calculations, and only then began to feel Luca could be right. Now Ston
37、eham and his co-workers have done the job more thoroughly, in a paper soon to be published in Physical Review Letters.11. The UCL team calculated the rates of electron hopping in a nose receptor that has an odorant molecule bound to it. This rate depends on various properties of the biomolecular sys
38、tem that are not known, but the researchers could estimate these parameters based on typical values for molecules of this sort.12. The key issue is whether the hopping rate with the odorant in place is significantly greater than that without it. The calculations show that it is which means that odou
39、r identification in this way seems theoretically possible. 13. But Horsfield stresses that thats different from a proof of Turins idea. So far things look plausible, but we need proper experimental verification. Were beginning to think about what experiments could be performed.14. Meanwhile, Turin i
40、s pressing ahead with his hypothesis. At Flexitral we have been designing odorants exclusively on the basis of their computed vibrations, he says. Our success rate at odorant discovery is two orders of magnitude better than the competition. At the very least, he is putting his money where his nose i
