Judging from tales about the rise and fall of empires, there is always a point when things are going so well that the emperors doubt that anything could ever go wrong. "Thrift," warned Nero’s adviser Seneca, "comes too late when you find it at the bottom of your purse. " In the Old World, nations grew fat and then lazy, until they collapsed under their own weight. But that was not to be our story. American greatness—the vision of the founders, the courage of the pioneers, the industry of the nation builders—reflected a mighty faith in the power of sacrifice as a muscle that made young nations strong. Banks were like gyms for the soul: the first savings banks in Boston and New York were organized as charities, where "bumble journeymen" could exercise good judgment, store their money and not be tempted to waste it on drink. Architect Louis Sullivan carved the word THRIFT over the door of his "jewel box" bank nearly a century ago, for it was private virtue that made public prosperity possible. That virtue died with the baby boom, but it had been ailing ever since the Depression, argues cultural historian David Tucker in the Decline of Thrift in America. That crisis, he writes, invited economists to recast thrift as "the contemptible vice which threw sand in the gears of our consumer economy. " A White House report in 1931 urged parents to let children pick out their own clothes and furniture, thereby creating in the child "a sense of personal as well as family pride in ownership, and eventually teaching him that his personality can be expressed through things. " Somewhere along the way, thrift did not just stop being a value; it became a folly. Saving was for suckers; you’d miss the ride, die leaving money on the table when you could have lived it up. There are no pockets in a shroud, as the saying goes. We once saved about 15% of our income. By the roaring 80s the rate was 4%; now we’re in negative numbers. Bob Hope liked to joke that "a bank is a place that will lend you money if you can prove that you don’t need it. " But that too changed as easy credit bloomed and usury became another of those vices that had somehow lost its juice. The average American has nine credit cards with a total $17, 000 balance. We borrow against our houses and pensions to live in a way that dares us to actually grow old. "Never invest in any idea you can’t illustrate with a crayon. " Fidelity mastermind Peter Lynch advised, but we embraced all kinds of investments about which we understood nothing except the hollow promise that they would never fail. When the economy began to swoon we kept spending, effectively sending ourselves rebate checks from accounts already way overdrawn, as if it would make us feel better to buy a new TV and charge it to our kids. George W. Bush has never been reluctant to frame policy debates in moral terms, targeting an "axis of evil", casting tax cuts as the removal of unfair burdens on hardworking people, calling tariff reduction a moral imperative. But thrift is one virtue he never invokes, and a restoration of restraint is a strain of conservatism he seldom promotes. In fact, it was after the most tragic day in modern U.S. history, when Bush urged people who wanted to help to go shopping, that profligacy officially replaced prudence as a patriotic duty. There’s no way to tell during this cun’ent distress whether we’re repenting or just retrenching. Thriftstore sales are up. Cats are shrinking. P. Diddy retired his private jet to save on gas. In hard times, people often rediscover the peace that prudence brings, when you try to spend a little less than you have because tomorrow might be worse. But that feels almost un-American; we’re optimists by nature, and we’ve been living large for so long that solvency feels like a sacrifice. It will take some sustained character education—and leadership—to understand that morning in America is more likely to come again if we prepare for midnight. According to the passage, which of the following statement is CORRECT

A. Some Americans save because they want to enjoy themselves.
B. Americans tend to be in debt because of over spending.
C. President Bush often puts emphasis on moral.
D. Thrift is believed as an act of patriotism in America.

Later the Greeks moved east from Cumae to Neapolis, the New City, a little farther along the coast where modern Naples now stands. We have a very good idea what life in this sun-splashed land was like during the Roman era because of the recovered splendor of Pompeii and Herculaneum. But as the well-trod earth of Campania continues to yield ancient secrets, Mastrolorenzo and Petrone, with their colleague Lucia Pappalardo, have put together a rich view of an earlier time and what may have been humankind’s first encounter with the primal force of Vesuvius. Almost all has come to light by chance. In May 2001, for example, construction workers began digging the foundation for a supermarket next to a desolate, weed-strewn intersection just outside the town of Nola. An archaeologist working for the province of Naples noticed several trances of burned wood a few feet below the surface, an indication of earlier human habitation. At 19 feet below, relicts of a perfectly preserved Early Bronze Age village began to emerge. Over the next several months, the excavation unearthed three large prehistoric dwellings: horseshoe shaped huts with clearly demarked entrances, living areas, and the equivalent of kitchens. Researchers found dozens of pots, pottery plates, and crude hourglass-shaped canisters that still contained fossilized traces of almonds, flour, grain, acorns, olive-pits, even mushrooms. Simple partitions separated the rooms; one hut had what appeared to be a loft. The tracks of goats, sheep, cattle, and pigs, as well as their human masters, crisscrossed the yard outside. The skeletons of nine pregnant goats lay in an enclosed area that included an animal pen. If a skeleton can be said to cower, the bones of an apparently terrified dog huddled under the eaves of one roof. What preserved this prehistoric village, what formed a perfect impression of its quotidian contents right down to leaves in the thatch roofs and cereal grains in the kitchen containers, was the fallout and surge and mud from the Avellino eruption of Vesuvius. Claude Albore Livadie, a French archaeologist who published the initial report on the Nola discovery, dubbed it "a first Pompeii". During May and June 2001, provincial archaeological authorities oversaw excavation of the site Mastrolorenzo hurried out to Nola, about 18 miles east of Naples. He and Pappalardo took samples of the ash and volcanic deposits, which contained chemical clues to the magnitude of the eruption. But then the scientific story veered off into the familiar opera buffa of Italian archaeology. The owner of the site agitated for construction of the supermarket to resume or to be compensated for the delay—not an unusual dilemma in a country where the backhoes and bulldozers of a modern economy clang against the ubiquitous remains of ancient civilizations. Government archaeologists hastily excavated the site and removed the objects. As it turns out, the supermarket was never built, and all that remains of a site that miraculously captured one of civilization’s earliest encounters with volcanic destruction is a hole in the ground on a vacant, weed-choked lot, the foundation walls of the huts barely visible. A small, weathered sign proclaiming the "Pompeii of Prehistory" hangs limply from a padlocked gate. Despite the loss of Nola as well as some other archaeological sites, Mastrolorenzo, Petrone, Pappalardo, and American volcanologist Michael Sheridan triggered world wide fascination when they summarized these findings in the spring of 2006 in the Proceedings of the National Academy of Sciences (PNAS). But their research went beyond mere archaeological documentation. The Avellino event, they wrote, "caused a social-demographic collapse and abandonment of the entire area for centuries. " The new findings, along with computer models, show that an Avellino-size eruption would unleash a concentric wave of destruction that could devastate Naples and much of its surroundings. In the world before Hurricane Katrina and the Indian Ocean tsunami, these warnings might have sounded as remote and transitory as those prehistoric footsteps. Not anymore. The site of Nola was compared to Pompeii because

A. they were both reported by French archaeologists.
B. they both gave us a good picture of ancient people’s life.
C. they both existed in the same age.
D. they were both in Campania.
