Less than a year ago, a new generation of diet pills seemed to offer the long-sought answer to our chronic weight problems. Hundreds of thousands of pound-conscious Americans had discovered that a drug combination known as "fen-phen" could shut off voracious appetites like magic, and the FDA had just approved a new drug, Redux, that did the same with fewer side effects. Redux would attract hundreds of thousands of new pill poppers within a few months. But now the diet-drug revolution is facing a backlash. Some of the nation’’s largest HMOs, including Aetna U.S. Healthcare and Prudential Healthcare, have begun cutting back or eliminating reimbursement for both pills. Diet chains like Jenny Craig and Nutri-System are backing away from them too. Several states, meanwhile, have restricted the use of fen-phen, last week the Florida legislature banned new prescriptions entirely and called on doctors to wean current patients from the drug within 30 days; it also put a 90-day limit on Redux prescriptions. Even New Jersey doctor Sheldon Levine, who touted Redux last year on TV and in his book The Redux Revolution, has stopped giving it to all but his most obese patients. The reason for all the retrenchment: potentially lethal side effects. Over the summer, the FDA revealed that 82 patients had developed detects in their heart valves while on fen-phen, and that seven patients had come down with the same condition on Redux. As if that weren’t bad enough, physicians reported that a woman who had been taking fen-phen for less than a month died of primary pulmonary hypertension, a fatal lung condition already associated with Redux. And an article in the Journal of the American Medical Association last month confirmed earlier reports that both fen-phen and Redux can cause brain damage in lab animals. These findings led the New England Journal to publish an editorial admonishing doctors to prescribe the drugs only for patients with severe obesity. Meanwhile, FDA asked drug makers to put more explicit warnings on fen-phen and Redux labels. Since mid-July, prescriptions for fen-phen have dropped 56%, and those for Redux 36%, according to IMS America, a pharmaceutical-market research firm. All that really does, however, is to bring the numbers down to where they should have been all along. Manufacturers said from the start that their pills offered a short-term therapy for the obese, not for people looking to fit into a smaller bathing suit. FDA approved Redux with just such a caveat, and when limited to these patients, the drugs may still make sense-despite the risks-because morbid obesity carries its own dangers, including heart disease, diabetes and stroke. Too often, however, Redux and fen-phen were peddled’’ to all comers, almost like candy. The current backlash, says Levine, is a "roller coaster that never should have happened." The statement "diet-drug revolution is facing a backlash" (Para. 2) is supported by the following facts except _______.

A. diet chains and some of the HMOs have removed their support for the pills
B. some states have limited or forbidden the prescriptions of the diet pin
C. in Florida, patients are told to turn away from the use of fen-phen within a month
D. Sheldon Levine, a New Jersey doctor, touted one of the pills on TV and in his book

The Super Bowl is one of the biggest events on the advertising calendar, as companies vie to produce the most memorable and innovative ads. The battle for the National Football League’s ultimate prize attracts more viewers than anything else on American television and provides a "symbolic pulsetaking" for the advertising industry every February, says John Frelinghuysen, an analyst at Bain and Company, a consultancy. But this year the patient is in poor health. All the advertising slots(广告摊位) for the 2008 Super Bowl had been sold by the end of November 2007, despite the $ 2.6 million price of each. For 2009 the price has risen to $ 3 million, but at least, ten slots (out of 67) are still looking for a buyer. General Motors, which ran 11 ads on Super Bowl Sunday in February 2008, has already said that it will not run any in 2009. America’s two other big carmakers, Ford and Chrysler, are likely to follow suit. Tellingly, Monster com, an online job-search company, said recently that it was buying a slot. Instead of the usual parade of expensive ads paying tribute to American consumerism, 2009’s Super Bowl will reflect a country in recession and indicate a hard year for the advertising industry. Most forecasts for next year say that ad spending in America will decline by 5% or more. Much depends on the fate of the automotive industry: carmakers and dealers normally spend around $ 20 billion a year on advertising, but Chrysler and Ford scaled back their expenditure by more than 30% in the first nine months of 2008, and are expected to make further cuts in 2009 as they struggle for survival. The car industry’s situation will hurt all media, but especially television. Analysts at BMO Capital Markets predict that total spending on television ads will fall by almost 9% next year. Only newspapers, where a decline of 12% is expected, are forecast to fare worse. Carmakers have already shifted some of their advertising spending to the Internet, and are likely to go further in 2009. Car ads make up 25% of advertising revenues for local television channels, and carmakers have been among the most consistent buyers of high-priced ads on national television. So far local stations have been most affected by falling spending oil advertising. National stations have been safer, because they operate on longer-term contracts with advertisers. But in the New Year they will also feel the chill, as companies fail to renew their contracts. Television, which has remained strong as print media have lost advertising dollars and readers to the Internet, could enter a decline of its own. "Next on the list is TV stations," says Anthony Diclemente, a media analyst at Barclays Capital. What may the carmakers resort to for promoting their automobiles and cutting down expenditure

A. Buying low-priced ads on national television.
B. Renewing new contracts with national stations.
C. Shifting their advertising spending to the Internet.
D. Relying on such print media as newspapers.
