What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure(暴露，接触) to loud music, and both now wear hearing aids（助听器） as a result. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary（暂时） hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells（细胞） somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分贝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather."I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
| Levels of Common Noises Normal conversation 50 — 65 dB Food blender 88 dB Jet plane flying above a person standing outside 103 dB Rock band during a concert 110 — 140 dB |
From Paragraph 1, we can learn that ___________ .
| A．loud music is a major cause of hearing loss |
| B．famous people may have hearing problems |
| C．teenagers should stay away from school bands |
| D．the problem of hearing damage is widely known |
In Paragraph 3, the underlined word "recondition" means__________ .
| A．not to be seen | B．to fill with sound |
| C．to become larger in size | D．to make good again |
The purpose of the chart at the end of the article is to show__________ .
| A．a list of harmful sounds |
| B．the effect of rock concerts |
| C．the noise levels of sounds |
| D．relationship between daily activities and hearing loss |
Which of the following statements will Dr. Sam Levine probably agree?
| A．When your ears feel warm, your hair cells are dead. |
| B．Drummer Andrew Sather gives good advice. |
| C．Many are at the risk of losing hearing. |
| D．Doctors know how to deal with hearing loss. |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid to cut the emission of greenhouse gases blamed for global warming.Thanks to special bacteria in their stomachs, kangaroo farts contain no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas. While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, livestock passing wind contribute a surprisingly high percentage of total emissions in some countries. "Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government. "And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said. Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep. Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. The idea is controversial（争议）, but about 20 percent of health conscious Australians are believed to eat the national symbol already. "It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal（散养动物）," said Peter Ampt of the University of New South Wales's institute of environmental studies.
1. According to the passage, global warming is now mainly caused by _____ .
A. methane B. carbon dioxide
C. livestock passing wind D. not mention in this passage
2. What does the underlined phrase “the idea”（paragraph 9）refer to? A. Australians should give kangaroo-style stomachs to cattle and sheep.
B. The bacteria could make the digestive process much more efficient.
C. Australians should farm fewer cattle and sheep and just eat more kangaroos. D. The bacteria could potentially save millions of dollars in feed costs for farmers.
3. How will Australian scientists solve the problem of global warming?
A. Eating more kangaroos.
B. Killing more cattle and sheep. C. Letting cattle and sheep pass less wind.
D. Transferring the special bacteria in kangaroos’ stomachs to cattle and sheep.
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.
1.What is the passage mainly about?
A. A review of two kinds of auctions. B. An introduction of trading robots.
C. A survey of the trading market. D. About trading alternatives.
2.Which of the following is true according to the text?
A. Mr Cliff’s robot traders have now been used in real-world markets.
B. Robot traders can evolve like creatures.
C. There is room for improvement in efficiency in trading markets.
D. The English auction is the most popular trading form.
3.What can we infer from the text?
A. Existing auctions cannot withstand market shocks
B. The Dutch auction is better than the continuous double auction
C. It’s hard for traders to reach a balanced price
D. The best type of auction takes place when the number of the buyers is equal to that of sellers
4.What’s the author’s attitude toward robot traders?
A. Prejudiced B. Objective C. Critical D. Optimistic
Chances are you’ve enjoyed a cup of coffee from Starbucks. Since the opening of the first Starbucks in 1971 as a vendor of high-quality coffee beans and brewing equipment, the company has expanded to become the most popular coffeehouse chain in the world. Its 14,000 stores in 43 countries sell coffee beverages, beans, teas, brewing equipment, pastries, and more. How did this happen?
Starbucks Chairman Howard Schultz took over the company in 1987. He recognized an untapped market in busy individuals in urban areas who could afford fine coffees. In 1995, Schultz hired Anna Niess and Will Chassaing to redesign his booming chain. In addition to laying the groundwork for Starbucks’ well-known symbols and distinctive style, they created a program that led to opening one store per day throughout the 1990s.
One thing that makes Starbucks so popular is the company’s vision of their stores as a “third place” to spend time in addition to work and home. It’s a cozy environment that serves as a meeting place. This attracts a loyal following of customers that come not only to drink coffee, but to relax, work, socialize, and attend cultural events.
Schultz still sees a great deal of potential for his company. Starbucks plans to have 40,000 stores worldwide with 20,000 in the US and Canada. The company is now a household name around the world.
Howard Schultz is the perfect example of a person living the American dream. After growing up in public housing, he received a football scholarship to Northern Michigan University. This allowed him to become the first in his family to graduate from college in 1975.
Schultz first experienced Starbucks as a salesman for Swedish drip coffeemakers on a trip to visit the Seattle company that had been buying his products. A year later, he joined the company. Conflict arose when Schultz recommended Starbucks sell brewed coffee in addition to beans and equipment. The owners disagreed, and in 1985, Schultz went on to start his own coffee shop, II Giornale. In 1987, the original Starbucks owners sold their company to Schultz, and refocused their attention on selling coffee beans and teas.
Schultz promoted an aggressive expansion of Starbucks throughout the US and Canada. When Starbucks began selling stock shares in 1992, he had already grown the chain to 165 stores. Throughout the expansion of Starbucks, Schultz has held strong principles of social responsibility. Starbucks takes good care of its employees with health insurance, stock options (认股权), and stable hours. In fact, under Schultz, Starbucks has been consistently ranked one of the best places to work in the US and UK.
Commitments to environmentalism, fair pay for coffee bean growers, and a positive contribution to society contribute to Schultz’s reputation as a truly ethical (道德的) businessman. That means with Schultz in charge of Starbucks, you can enjoy your coffee with a clear conscience.
Which of the following statements is NOT true?
Starbucks sells coffee beverages, beans, teas, brewing equipment, pastries and more.
The original Starbucks owners focused their attention on selling coffee beans and brewing equipment until 1987.
Starbucks has been the best place to work in the US and UK.
It was Anna Niess and Will Chassaing who redesigned Starbucks’s well- known symbols and style.

Is there a magic cutoff period when offspring become accountable for their own actions? Is there a wonderful moment when parents can become spectators (旁观者) in the lives of their children and shrug, "It' s their life," and feel nothing?
When I was in my twenties, I stood in a hospital corridor waiting for doctors to put a few stitches in my son' s head. I was asked, "When do you stop worrying?" A nurse said, "When they get out of the accident stage." My mother just smiled faintly and said nothing.
When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked incessantly, disrupted (打断) the class, and was headed for a career making license plates. As if to read my mind, a teacher said, "Don't worry. They all go through this stage, and then you can sit back, relax, and enjoy them." My mother listened and said nothing.
When I was in my forties, I spent a lifetime waiting for the phone to ring and the cars to come home, the front door to open.
My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted by my mother' s wan ( 淡淡的 ) smile and her occasional words, "You look pale. Are you all right? Call me the minute you get home."
Can it be that parents are sentenced to a lifetime of worry? Is concern for one another handed down like a torch to blaze the trail of human frailties and the fears of the unknown? Is concern a curse? Or is it a virtue that elevates us to the highest form of life?
One of my children became quite irritable recently, saying to me, "Where were you? I' ve been calling for three days, and no one answered. I was worried! ! !"
I smiled a wan smile.

When the first spring flowers blossom, Easter comes. It is the oldest Christian feast, in memory of the resurrection (复活) of Jesus Christ.
Along with the traditional Easter walk or outing, the giving of Easter eggs and, more recently, of Easter presents is a main feature of the feast. Parents give their children “Easter eggs” – colored and boiled eggs, chocolate eggs, marzipan eggs – Easter bunnies, sweets, and other gifts. In some German regions, children virtually “collect” Easter eggs from their relatives, especially their godparents.
Usually, the Easter eggs are carefully hidden in the garden or in the house and the children must search for them on the morning of the Sunday. They are told that the Easter bunny has brought them. This anonymous, mysterious bunny is like Santa Claus at Christmas. But it is less of an “educational” figure than Santa Claus is, since the eggs are not given to children as rewards for being good.
Some Easter egg games have been preserved at certain places in Germany or have even been newly developed. Children try to outdo others in rolling colored eggs down grassy slopes, for instance, or they knock the eggs’ pointed ends together and the child whose egg does not shatter gets the broken one, too. In some places, this custom was even used as the name of local festival.
