Computerised trading agents may help humans build better markets
THANKS to declining markets, investment banks are getting rid of many of their highly-paid traders. When markets recover, the banks might be tempted to replace them with rather cheaper talent. One alternative has been around for a while but has yet to catch on: autonomous trading agents-computers programmed to act like the human version without such annoying costs as holidays, lunch breaks or bonuses. Program trading has, of course, been done before; some blamed the 1987 stock market crash on computers instructed with simple decision-making rules. But robots can be smarter than that.
Dave Cliff, a researcher at Hewlett-Packard Laboratories in Bristol, England, has been creating trading robots for seven years. In computer simulations he lets them evolve "genetically", and so allows them to adapt and fit models of real-world financial markets. His experiments have suggested that a redesign of some markets could lead to greater efficiency. Last year, a research group at IBM showed that Mr Cliff"s artificial traders could consistently beat the human variety, in various kinds of market. Nearly all take the shape of an auction(拍卖). One well-known type is the English auction, familiar to customers of the salesrooms(拍卖场)of Christie"s and Sotheby"s, where sellers keep mum on their offer price, and buyers increase their bids by stages until only one remains.
At the other extreme is the Dutch auction, familiar to 17th-century tulip-traders in the Netherlands as well as to bidders for American Treasury bonds. Here, buyers remain silent, and a seller reduces his price until it is accepted. Most markets for shares, commodities, foreign exchange and derivatives are a mixture of these two types: buyers and sellers can announce their bid or offer prices at any time, and deals are constantly being closed, a so-called "continuous double auction".
Mr Cliff"s novel idea was to apply his evolutionary computer programs to marketplaces themselves. Why not, he thought, try and see what types of auction would let traders converge(趋同) most quickly towards a balance price? The results were surprising. In his models, auctions that let buyers and sellers bid at any time like most of today"s financial exchanges were less efficient than ones that required relatively more bids from either buyers or sellers. These "evolved auctions" also withstood big market shocks, such as crashes and panics, better than today"s real-world versions. Mr Cliff"s most recent results, which will be presented in Sydney, Australia, on December 10th, show that the best type of auction for any market depends crucially on even slight differences in the number of buyers and sellers.
Bank of America has been investigating these new auctions, along with robotic traders, for possible use in electronic exchanges. The hope is that today"s financial auctions and online marketplaces might work better by becoming more like their English and Dutch ancestors.

举一反三

“What’s in a name?”According to Shakespeare’s Romeo and Juliet,there is not too much.“That which we call a rose by any other name would smell as sweet.”But Shakespeare may have been wrong.In most cultures,names matter a great deal.
Americans choose names for their children with care.Parents usually think about the impression a name gives,not its meaning.Most Americans would consider a“Jennifer”more attractive than a “Bertha”,for example.The last name,or,surname,must also be considered when choosing a first and middle name.A name like Lester Chester Hester would sound poetic,but odd.Parents would avoid names that remind them of people they don’t like.On the other hand,people might name their children after a respected elderly relative or even a famous person.The popularity of certain names can change with each new generation.Names that were once common,like Fanny or Elmer,sound old-fashioned today.But other names—like John and David,Mary and Sarah—have stood the test of time and continue to be favorites.
People in Ameica don’t always call their friends and relatives by their given names.Instead,they often use nicknames.Sometimes nicknames are short forms of a longer name.For instance,a girl named Elizabeth may be called Lisa,Beth or Betsy.As children grow up,they may decide for themselves which nickname they wish to be called.Some people just go by the initials of their first and middle names,like B.J.or R.C.And of course,people may call their children or their sweethearts other special nicknames.Often they have a “sweet” flavor,like Honey or Sugar.What’s in a name? A world of significance.So if you’re choosing an English name for yourself,take care to choose a good one.Amade-up name could sound strange to native English speakers.And a translation of your Chinese name may not make an appropriate name,either.But a good name can leave a positive and lasting impression.As an American politician once said,“In real life,unlike in Shakespeare,the sweetness of the rose depends upon the name it bears.”

4.The author will name a newly born baby girl             .

Yesterday"s paper had a short article about the Coming-of-Age ceremony in a large city in Japan. According to the article, the mayor of the city formally apologized to an enraged professor who delivered a speech at the ceremony that was all but ignored by 20-year-olds in the city.
The officials prepared 7,000 seats in a gymnasium where the ceremony was held for the 17,000 twenty-year-olds residing in the city. But most of the seats were empty during the speech. And many of the 20-year-olds who did show up ignored the professor and spoke among themselves or talked on their mobile phones. Some even made a ruckus (***动) outside the gymnasium.
One 20-year-old who attended the ceremony said youngsters came to the ceremony not to
listen to speeches but to see their classmates. The mayor criticized the young generation at a news conference on Tuesday, saying such behavior "is symbolic of the postwar era which failed to
nurture healthy character and social intelligece."
Personally I feel people should not generalize the whole generation or the whole era when he criticizes something. But it is also true generation gap is getting bigger and bigger regarding the ceremony of Coming-of-Age Day. So far this ceremony has been held with citizens" tax money. Many older generations understand this festival as an entrance ceremony of adults" world which requires maturity including responsibility, patience, and cooperativeness. Older people tend to be "educational" to younger ones, while younger people tend to feel they finally obtain a right to behave freely because they are now adults. Though, ironically, young people have to ask their parents to buy them new clothes for the ceremony.
It is about time to change the way we celebrate this festival, I think. The idea of blessing new 20-year-olds is not so bad. But there seems to be some other ways to celebrate more properly. The present way seems to me a little superficial and materialistic. It can provide solutionless arguments between different generations, instead of friendships and respects. Instead of eternally complaining about the young"s behaviors at the ceremonies, people should consider how they can make their ceremonies worthier, I feel.
1.We can infer from the passage that 
A.in Japan, girls and boys, when they are 20 years old, come to their adulthood

3.According to the author _________
A.the festival is an entrance ceremony of adults’ world which requires maturity including responsibility, patience, and cooperativeness
B.the young people tend to obtain a right to behave freely because they are now adults

The most intensive period of speech and language development for humans is during the first three years of life, a period when the brain is developing and maturing. These skills appear to develop best in a world that is rich with sounds, sights, and consistent(一致的,协调的,相容的)exposure(揭发)to the speech and language of others.
There is increasing evidence suggesting that there are "critical periods" for speech and language development in infants and young children. This means that the developing brain is best able to absorb a language, any language, during this period. The beginning signs of communication occur during the first few days of life when an infant learns that a cry will bring food, comfort, and companionship.  As they grow, infants begin to sort out the speech sounds (phonemes) or building blocks that compose the words of their language. Research has shown that by six months of age, most children recognize the basic sounds of their native language
As the speech mechanism (jaw, lips, and tongue) and voice mature, an infant is able to make controlled sound. By six months of age, an infant usually babbles or produces repetitive syllables such as "ba, ba, ba" or "da, da, da." By the end of their first year, most children have mastered the ability to say a few simple words. Children are most likely unaware of the meaning of their first words, but soon learn the power of those words as others respond to them.
By eighteen months of age, most children can say eight to ten words. By age two, most are putting words together in crude sentences such as "more milk." During this period, children rapidly learn that words symbolize or represent objects, actions, and thoughts. At this age they also engage in representational or pretend play. At ages three, four, and five, a child"s vocabulary rapidly increases, and he or she begins to master the rules of language.
1.According to the passage, which of the statements is NOT true
A.The developing brain is best able to absorb any language.
B.The beginning signs of communication occur during the first few days of life.
C.By six months of age, all children recognize the basic sounds of their native language.
D.By 2, children rapidly learn that words symbolize or represent objects, actions, and thoughts.
2.We can infer from the passage that____
A.by six months of age, an infant must babble or produce repetitive syllables
B.by their first year, most children are most likely aware of the meaning of their first words
C.by 2, children rapidly learn that words symbolize or represent objects, actions, and thoughts
D.the brain development is critical to develop children’s speech and language ability
3.That there are “critical periods” for speech and language development in infants and young children means ______
A.that children are so young that it is easy for them to study
B.that the developing brain is best able to absorb a language, any language
C.that the children are eager to learn the language
D.that we must take care of children
4 In Paragraph 3, the underlined word “mechanism” can be replaced by ______.
A.organs          B.skills            C.abilities          D.habits
