Physicians and patients are questioning thewisdom of the ban, which will have an insignificant effect on ozone but a measurable impact on wallets: the reformulated brand-name alternatives can be three times as expensive, raising the cost to about $40 per inhaler. The issue is even more disconcerting considering that asthma disproportionately affects the poor and that according to recent surveys, an estimated 20 percent of asthma patients are uninsured.BThe decision to make the change was political, not medical or scientific, says pharmacist Leslie Hendeles of the University of Florida, who co-authored a 2007 paper in the New England Journal of Medicine explaining the withdrawal and transition. In 1987 Congress signed on to the Montreal Protocol on Substances That Deplete the Ozone Layer, an international treaty requiring the phasing out of all nonessential uses of CFCs. At that time, medical inhalers were considered an essential use because no viable alternative propellant existed. In 1989 pharmaceutical companies banded together and eventually, in 1996, reformulated albuterol with hydrofluoroalkane.CThe transition began quietly, but as more patients see their prescriptions change and costs go up, many question why this bail must begin before generics become available. At least one member of the FDA advisory committee, Nicholas J. Gross of the Stritch-Loyola School of Medicine, has publicly regretted the decision, recanting his support and requesting that the ban be pushed back until 2010, when the first patent expires.DGross notes that the decision had nothing to do with the environment Albuterol inhalers contributed less than 0.1 percent of the CFCs released when the treaty was signed. Lt's a symbolic issue Gross remarks. Some skeptics instead point to the billions of dollars to be gained by the three companies holding the patents on the available HFA-albuterol inhalers, namely Glaxo-SmithKline, Schering-Plough and Teva. Althoughthe FDA advisory committee recognized that the expenses would go up, Hendeles says, it also believed that the companies would help defray the added costs for individuals, Firms, for instance, had committed to donating a million HFA inhalers to clinics around the country. According to Hendeles, GlaxoSmithKline did not follow through, although Schering-Plough and Teva did. GlaxoSmithKline did not respond to requests for comment.EThe issue now, Hendeles says, is that pharmaceutical-grade CFCs are in short supply, and the public faces the risk of a shortage of albuterol inhalers if the FDA does not continue promoting the production of HFA inhalers. He posits that even costs of generics would go up as CFCs become scarcer. Gross disagrees, saying that the inhaler shortage and the closure of CFC manufacturing plants are a result of the ban.FThe HFA inhalers also have encountered resistance because some asthmatics insist that they do not work as well as the CFC variety. But, Hendeles says, the differences are in the mechanics and maintenance—unlike CFC inhalers, the HFA versions must be primed more diligently and rinsed to accommodate the stickier HFA formulation. They also run out suddenly without the warning with a CFC inhaler, that the device is running low. Pharmacists may not tell people of these things, and the doctors don't know, Hendeles says.GThe main public health issue in this decision may be the side effects of the economics, not the drug chemistry. Multiple studies have shown that raising costs leads to poorer adherence to treatment. One study discovered that patients took 30 percent less amtiasthma medication when their co-pay doubled. In the ease of a chronic disease such as asthma, it is particularly difficult to get people to follow regular treatment plans. Generally speaking, for any reason you don’t take medication, cost makes it more likely” that you do not, comments MichaelChernew, a health policy expert at Harvard Medical School.HSuch choices to forgo medication could affect more than just the patients themselves. For example, Hendeles points out, in a pregnant mother with untreated asthma, less oxygen is delivered to the fetus, which can lead to congenital problems and premature birth. And considering that the disease disproportionately strikes the poor, what seemed to be a good, responsible environmental decision might in the end exact an unexpected human toll.Question 14-18Use the information in the passage to match the people (listed A-C) with opinions or deeds below. Write the appropriate letters A-C in boxes 14-18 on your answer sheet.NB you may use any letter more than onceA Nicholas J. GrossB Michael ChernewC Leslie Hendeles14.

Internet security experts have long known that simple passwords do not fully defend online bank accounts from determined fraud artists. Now a study suggests that a popular secondary security measure provides little additional protection.2.The study, produced jointly by researchers at Harvard and the Massachusetts Institute of Technology, looked at a technology called site-authentication images. In the system, currently used by financial institutions like Bank of America, ING Direct and Vanguard, online banking customers are asked to select an image, like a dog or chess piece, that they will see every time they log in to their account.3.The idea is that if customers do not see their image, they could be at a fraudulent Web site, dummied up to look like their bank’s, and should not enter their passwords.4.The Harvard and M.I.T. researchers tested that hypothesis. In October, they brought 67 Bank of America customers in the Boston area into a controlled environment and asked them to conduct routine online banking activities, like looking up account balances. But the researchers had secretly withdrawn the images.5.Of 60 participants who got that far into the study and whose results could be verified, 58 entered passwords anyway. Only two chose not tolog on, citing security concerns.6.“The premise is that site-authentication images increase security because customers will not enter their passwords if they do not see the correct image,” said Stuart Schechter, a computer scientist at the M.I.T. Lincoln Laboratory. “From the study we learned that the premise is right less than 10 percent of the time.”7.He added: “If a bank were to ask me if they should deploy it, I would say no, wait for something better,” he said.8.The system has some high-power supporters in the financial services world, many trying to comply with new online banking regulations. In 2005, the Federal Financial Institutions Examination Council, an interagency body of federal banking regulators, determined that passwords alone did not effectively thwart intruders like identity thieves.9.It issued new guidelines, asking financial Web sites to find better ways for banks and customers to identify each other online. January 2007 was set as the compliance date, though the council has yet to begin enforcing the mandate.10.Banks immediately knew what they did not want to do: ask customers to download new security software, or carry around hardware devices that feed them PIN codes they can use to authenticate their identities. Both solutions would add an extra layer of security but, the banks believed, detract from the convenience of online banking.11.The image system, introduced in 2004 by a Silicon Valley firm called PassMark Security, offered banks a pain-free addition to their security arsenals. Bank of America was among the first to adopt it, in June 2005, under the brand name SiteKey, asking its 21 million Web site users to select an image from thousands of possible choices and to choose a unique phrase they would see every time they logged in.12.SiteKey “gives our customers a fairly easy way ofauthenticating the Bank of America Web site,” said Sanjay Gupta, an e-commerce executive at the bank. “It was very well received.”13.The Harvard and M.I.T. researchers, however, found that most online banking customers did not notice when the SiteKey images were absent. When respondents logged in during the study, they saw a site maintenance message on the screen where their image and phrases should have been pictured. The error message also had a conspicuous spelling mistake, further suggesting something fishy.14.Mr. Gupta of Bank of America said he was not troubled by the results of the survey, and stressed that SiteKey had made the bank’s Web site more secure. He also said that the system was only a single part of a larger security blanket. “It’s not like we’re betting the bank on SiteKey,” he said.15.Most financial institutions, like Bank of America, have other ways to tell if a customer is legitimate. The banks often drop a smallsoftware program, called a cookie, onto a user’s PC to associate the computer with the customer. If the customer logs in from another machine, he may be asked personal questions, like his mother’s maiden name.16.Rachna Dhamija, the Harvard researcher who conducted the study, points out that swindlers can use their dummy Web sites to ask customers those personal questions. She said that the study demonstrated that site-authentication images are fundamentally flawed and, worse, might actually detract from security by giving users a false sense of confidence.17.RSA Security, the company that bought PassMark last year, “has a lot of great data on how SiteKey instills trust and confidence and good feelings in their customers,” Ms. Dhamija said. “Ultimately that might be why they adopted it. Sometimes the appearance of security is more important than security itself.”(811 words)Questions 1-5Do the following statements agree with the information given in the passage? Please writeTRUE if the statement agrees with the writerFALSE if the statement does not agree with the writerNOT GIVEN if there is no information about this in the passage1.According to internet security experts, secondary security measures provide little additional protection against fraud.2.In the Harvard and MIT study, two subjects didn’t log on without seeing the correct pictures.3.According to Schechter, more than 90% of online banking customers studied logged on without seeing the right pictures.4.The image system is the only security measure that the banks mentioned in the passage have currently.5.Bank of America is the first bank that adopted the image system.Questions 6-13Answer the following questions or complete the following sentences by choosing NO MORE THAN THREE WORDS for each answer.6.What is ING Direct and Vanguard?7.What might online banking customers be cheated to give at a fraudulent Web site?8.What may stop online banking customers from using new verification methods?9.The key to online banking security is to verify the ______ of customers.10.Where is PassMark Security located?11.What is the reason why SiteKey is popular among online banking customers?12.What was used instead of images in the Harvard and M.I.T. study?13.How many security methods are mentioned in this passage?Answer keys1. 第一段“Now a study suggests that a popular secondary security measure provides little additional protection.”似与问题文字很接近，但是原文中a popular secondary security measure是指特定的一个措施，而非泛指所有secondary security measure。
