1.There is nothing more possible than a new hip or knee that can put the spring back in your step.Patients receiving joint implants (移植) often are able to resume many of the physical activitiesthey love, even those as vigorous as tennis and hiking. No wonder, then, that joint replacement is growing in popularity.In the United States in 2007, surgeons performed about 806,000 hip and knee implants (the joints most commonly replaced), double the number of performed a decade earlier. Though these procedures have become routine, they are not failure free."Implants must sometimes be replaced," said Dr. Henrik Malchau, an orthopedic surgeon (矫正外科医生) at Massachusetts General Hospital in Boston. A study published in 2007 found that 7 percent of hips implanted in Medicare patients had to be replaced within seven and a half years."The percentage may sound low, but the finding suggests that thousands of hip patients eventually require a second operation," said Dr. Malchau. Those patients must endure additional recoveries,often painful, and increased medical expenses.The failure rate should be lower, many experts agree. Sweden, for instance, has a failure rateestimated to be a third of that in the United States. Sweden also has a national joint replacement registry, a database of information from which surgeons can learn how and why certain procedures go wrong. A registry also helps surgeons learn quickly whether a specific type of implant is particularly problematic. "Even country that has developed a registry has been able to reduce failure rates significantly," said Dr. Daniel Berry, chief of orthopedic surgery at the Mayo Clinic in Rochester, Minn.A newly formed American Joint Replacement Registry will begin gathering data from hospitals in the next 12 to 18 months. It's good news for those who are considering replacing a knee or hip.People who need a new knee or hip would possibly feel __ about data gathering inthe U.S.

3.The first European stock exchange was established in Antwerp, Belgium(比利时), in 1531.There were no stock exchanges in England until the 1700’s. A man wishing to buy or sell shares of stock had to find a broker(agents) to transact his business for him. In London, he usually went to a coffee house, because brokers often gathered there. In 1773, the brokers of London formed a stock exchange.　　In New York City, brokers met under an old button wood tree on Wall Street. They organized the New York Stock Exchange in 1792.The American Stock Exchange, the second largest in the United States, was formerly called the Curb Exchange because of its origin on the streets of New York City.　　A stock exchange is a market place where member brokers buy and sell stocks and bonds(债券) of American and foreign businesses on behalf of the public. A stock exchange provides a market place for stocks and bonds in the same way a board of trade does for commodities. The stockbrokers receive a small commission on each transaction they make.　　The stockholder may sell his stock wherever he wants to unless the corporation has some special rule to prevent it. Prices of stock change according to general business conditions and the earnings and future prospects(前景) of the company. If the business is doing well, the stockholder may be able to sell his stock for a profit. If it is not, he may have to take a loss.Which of the statements is true?

5.根据以下资料，回答103-106题。 　　The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported Wednesday．Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is covering small island nations and threatening to destroy the low-lying, densely-populated low regions around the globe. 　　The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences rising oceans．It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change (IPCC), according to the authors. 　　Rising sea levels are driven by two things: the thermal expansion of sea water, and additional water from melting sources of ice．Both processes are caused by global warming．The ice sheet that sits atop Greenland, for example, contains enough water to raise world ocean levels by seven meters, which would bury sea-level cities from Dhaka to Shanghai. 　　Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say．But up to now, there has been a puzzling gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans. 　　The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reunite the models with observed data．Using new techniques to assess ocean temperatures to a depth of 700 meters from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimeter-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC. 106 The rise in water levels is especially dangerous for small island nations and __.

10.Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares.The player then taps the squares where the numbers had been, in order from 1 to 9.People can do it.But no human competitor has ever completed the game faster or more accurately thanAyumu the chimp.For almost five years Ayumu remains undefeated.Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp’s ability.Humphrey suspects Ayumu’s brain may have a condition that allows the chimp to see numbers as colors.This would mean that Ayumu may see a color glow after the numbers disappears.Then, instead of remembering the numbers, he remembers a sequence of colors, each associated with a number.The condition that Humphrey believes Ayumu may have is called synesthesia.Humans withsynesthesia may associate numbers and letters with colors.For example, a person may see thenumber “5” as the color blue.Until now, scientists had assumed only humans could havesynesthesia.Humphrey found the inspiration for his idea at a 2011 scientific conference.There, he heard apresentation about Ayumu’s memory abilities and another talk about synesthesia.He then put the two ideas together.Not everyone is convinced that Humphrey is correct.Primatologist Tetsuro Matsuzawa of thePrimate Research Institute at Kyoto University in Japan has spent decades studying the amazingmemories of chimpanzees, including Ayumu.He maintains that chimps simply have faster memory recall than people.Which of the following is true of Nicholas Humphrey?

11.It’s interesting that technology often works as a servant for us, yet frequently we become a servantto it. E?mail is a useful tool but many feel controlled by this new vehicle. The averagebusinessperson is getting about 80 e?mails per day and many feel that about 80% of the messagesin their “In Box” are of little or no value.So, I have four suggestions to help you to become better at “Easing E?mail”.1.Get off the lists. The best way to deal with a problem is to never have it. If you are receiving a lotof unwanted e?mails, ask to be removed from the various lists. This would include your inclusionin unwanted “cc” lists(抄送名单).2.“Unlisted address”.Just like getting an “unlisted” telephone number that you share only withthose whom you want to give direct access, you might want to get a separate e?mail address onlyfor the important communications you wish to receive.3.Check it once or twice per day.Many I speak with are becoming chained to their email server,monitoring incoming email on a continuous basis. Maybe this is because e?mail creates its own sense of urgency, but most of the communications are not all that urgent. I respond to them a couple of times per day.4.Deal with it. As you open each e?mail do one of the following:a.If it requires a quick response, respond to it and delete it.b.If it requires a response but is not the best use of your time, try to find someone else to do it.c.If it is going to take any serious amount of time to respond, schedule it for action in your Day Planner and then download the message, save it, or print it out for future action.I personally receive approximately 250 e?mails per day and by practicing the suggestions above, I can handle that volume in about an hour, taking advantage of this fantastic tool but not being controlled by it to the distraction(分心)of more important tasks in my day.For the important communications, the writer suggests that you .

13.根据以下资料，回答25-28题。A man once said how useless it was to put advertisements in the newspapers．"Last week," said he, "my umbrella was stolen from a London Church．As it was a present, I spent twice its worth in advertising, but didn't get it back." 　　"How did you write your advertisement?" asked one of the listeners, a merchant. 　　"Here it is," said the man, taking out of his pocket a slip cut from a newspaper．The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella．The gentleman who finds it will receive ten shillings on leaving it at No．10 Broad Street．" 　　"Now," said the merchant, "I often advertise, and find that it pays me well．But the way in which an advertisement is expressed is of great importance．Let us try for your umbrella again, and if it fails, I'll buy you a new one." The merchant then took a slip of paper out of his pocket and wrote: "If the man who was seen to take an umbrella from the City Church last Sunday evening doesn't wish to get into trouble, he will return the umbrella to No, 10 Broad Street．He is well known." This appeared in the paper, and on the following morning, the man was astonished when he opened the front door．In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown in, and his own was among the number．Many of them had notes, fastened to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter.25 The result of the first advertisement was that __.
