单选题St. Patrick's Day is celebrated on March 17, his religious feast day and the anniversary of his death in the fifth century. Legend has it that this patron saint had given a sermon from a hilltop that drove all the snakes from Ireland. He also used the three-leafed shamrock to represent the Trinity-how the Father, the Son, and the Holy Spirit could all exist as separate elements of the same entity-and converted the pagans to Christianity. The Irish have observed this day as a religious holiday for hundreds of years. People wear green in memory of the Emerald Isle and wear shamrocks. The first St. Patrick's Day parade, however, took place not in Ireland, but in the United States. Irish soldiers serving in the English military marched through New York City on March 17, 1762. Along with their music, the parade helped the soldiers, as well as fellow Irishmen serving in the English army, to reconnect with their Irish roots. Over the next thirty-five years, Irish patriotism among American immigrants flourished, prompting the rise of so-called "Irish Aid" societies, like the Friendly Sons of Saint Patrick and the Hibernian Society. Each group would hold annual parades featuring bagpipes (which actually first became popular in the Scottish and English armies) and drums. Up until the mid-nineteenth century, most Irish immigrants in America were members of the Protestant middle class. When the Great Potato Famine hit Ireland in 1545, close to a million poor, uneducated, Catholic Irish began to pour into America to escape starvation. Despised for their religious beliefs and funny accents by the American Protestant majority, the immigrants had trouble finding even menial jobs. When Irish Americans in the country's cities took to the streets on St. Patrick's Day to celebrate their heritage, newspapers portrayed them in cartoons as drunk, violent monkeys. However, the Irish soon began to realize that their great numbers endowed them with a political power that had yet to be exploited. They started to organize, and their voting block, known as the "green machine," became an important swing vote for political hopefuls. Suddenly, annual St. Patrick's Day parades became a show of strength for Irish Americans, as well as a must-attend event for a slew of political candidates. In 1948, President Truman attended New York City's St. Patrick's Day parade, a proud moment for the many Irish whose ancestors had to fight stereotypes and racial prejudice to find acceptance in America.

单选题Lou Dobbs is apparently larger than life , which is pretty much just the way he wants it. When you enter the Midtown Manhattan studio of his syndicated radio show, the first thing you see is Big Lou—in a pinpoint shirt, striped tie, and dark-blue suit adorned with de rigueur flag pin. With his waves of sandy hair, confident gaze, and glint of a smile, the 64-year-old is the essence of Distinguished Broadcaster. I approach to shake his hand. "Hello, sir!" bellows an emerging presence at the door at the opposite end of the room. That"s the real Lou Dobbs, in argyle sweater, jeans, and a Rolex baseball cap. He waves me over. "Let"s go get a sandwich!" The other Lou is actually a life-size cardboard cutout, designed for radio trade shows and now part of the studio trimmings that include giant posters for his bestselling books. Cardboard Lou is so convincingly wrought that I was, believe it or not, certain it was he. Dobbs jokes it"s slimmer and trimmer than he is, but the line also unintentionally raises larger questions about who the real Lou Dobbs is: True Believer or Ideological Mercenary? Right now, depending on whom you ask, Dobbs is the most despised, or best-loved, broadcaster in America. The questions about his identity matter, especially as Dobbs says he"s contemplating a third-party run for national office in 2012, either for the U.S. Senate or, incredibly, the White House. Whichever route he takes, the erstwhile voice of the financial world—the Cronkite for the business community for two decades—is clearly casting about for his next act. In 1981 Dobbs was one of the first business anchors at CNN and helped build the upstart. Steady, authoritative, and Harvard-credentialed, Dobbs won a Peabody for his coverage of the 1987 stock market crash and an Emmy for lifetime achievement. Then 9/11 and Wall Street scandals like Enron transformed—or transmogrified—him into an opinion-spewing, rabble-rousing provocateur. You could count on Fox"s Bill O"Reilly to attack from the right, and MSNBC"s Keith Olbermann from the left. By contrast, Dobbs was a bilious brew on CNN. Confoundingly, he also was hard to peg, an assortment of contradictions that reflected either independence or opportunism. For example, he seemed to have genuine concerns for U. S. jobs and empathy for the middle class, yet it"s hard to be a paragon of the people when you have your own plane and preside over a 300-acre farm, Hickory Hollow, in the suburbs of New York City. He wants us all to buy American, yet that twin-engine Hawker jet of his was made in the U. K. by British Aerospace. He has railed against illegal aliens yet professed support for immigration. He opposed outsourcing, globalization, and unfettered trade yet calls himself a champion of free enterprise. He has little use for unions or corporations. He"s pro-choice and anti-gun-control. He wants out of Iraq and Afghanistan. He despises "elites" yet is an Ivy Leaguer. He has denounced the Pope, the United Nations, bailouts, and Columbus Day. He called for the impeachment of George W. Bush, and relentlessly skewers Barack Obama, whom he mocks as "our supreme leader." For the past eight years Dobbs has been a populist madman. But then, in November, CNN cut him loose, though neither party to the breakup will officially describe it that way. Positioning itself as a neutral in the ideological cable wars between Fox and MSNBC, CNN concluded that Dobbs"s fulminations had ceased to have utility, since his ratings weren"t very good; it didn"t help either that Dobbs was perceived at CNN as leaning right when a lot of folks there happened to lean left. An executive at Time Warner, which owns CNN (as well as Fortune), calls it a divorce between spouses who hadn"t been getting along for some time. Dobbs walked away with upwards of $ 8 million, according to sources who asked for anonymity. Neither Time Warner nor Dobbs would comment on the terms of his contractual release. Nobody, though, disputes that Dobbs was stunned that CNN was ending his run of nearly 30 years (interrupted only by a much-lampooned two-year interlude at space, com during the dotcom bubble). He announced his departure on the air and was gone minutes later, describing his exit in what sounded like a stump speech. With a huge digital Stars and Stripes waving behind him, he said: "Over the past six months it"s become increasingly clear that strong winds of change have begun buffeting this country... Some leaders in media, politics, and business have been urging me to go beyond my role here at CNN and to engage in constructive problem solving, as well as to contribute positively to a better understanding of the great issues of our day." Strong winds indeed. He says now the hurt is gone and he is "exhilarated" to have fresh choices. Fox presumably would be thrilled to have him on its business channel or in its cable stable with such bloviating stallions as Bill O"Reilly and Sean Hannity. Even without a TV presence for the moment, Dobbs can roar away on his daily three-hour radio news). And while he"s wise enough to acknowledge the hassles of politics, he is altogether charmed by the idea of elected office. "It"s flattering that so many people have urged me to consider it," he says. So who are those people? Dobbs declines to say. (from Fortune , January 18, 2010)

单选题Memory Brains are different from computers, but the analogy can be helpful. Like the PC on your desk, your mind is equipped with two basic types of memory: "working memory" for juggling information in the present moment, and "long-term memory" for storing it over extended periods. Contrary to popular wisdom, our brains don't record everything that happens to us and then bury it until a hypnotist or a therapist helps us dredge it up. Most of what we perceive hovers briefly in working memory, a mental play space akin to a computer's RAM, then simply evaporates. Working memory enables you to perform simple calculations in your head or retain phone numbers long enough to dial them. And like RAM, it lets you analyze and invent things without creating a lasting record. Long-term memory acts more like a hard drive, physically recording past experiences in the brain region known as cerebral cortex. The cortex, or outer layer of the brain, houses a thicket of 10 billion vine—like nerve cells, which communicate by relaying chemical and electrical impulses. We can will things into long-term memory simply by rehearsing them. But the decision to store or discard a piece of information rarely involves any conscious thought. It's usually handled automatically by the hippocampus, a small, two-winged structure nestled deep in the center of the brain. Like the key-board on your computer, the hippocampus serves as a kind of switching station. As neurons out in the cortex receive sensory information. They relay it to the hippocampus. If the hippocampus responds, the sensory neurons start forming a durable network. But without that act of consent, the experience vanishes forever. By storing only the information we're most likely to use, our brains make the world manageable. Perfect retention may sound like a godsend, but when the hippocampus gets overly permissive, the results can be devastating. At the other end of the spectrum stands impairments of the memory, which can be caused by brain surgery as well as normal aging. Other memory busters include depression, anxiety and a simple lack of stimulation—all of which keep us from paying full attention to our surroundings. What, then, are the best ways to protect your memory? Obviously, anyone concerned about staying sharp should make a point of sleeping enough and managing stress. And because the brain is at the mercy of the circulatory system, a heart-healthy lifestyle may have cognitive benefits as well.
