单选题{{B}}Text 3{{/B}} You may fall prey to a nonviolent but frightening and fast-growing crime: identity theft. It happens to at least 500, 000 new victims each year, according to government figures. And it happens very easily because every identification number you have Social Security, credit card, driver's license, telephone- "is a key that unlocks some storage of money or goods," says a fraud program manager of the US Postal Service. "So if you throw away your credit card receipt and I get it and use the number on it, I'm not becoming you, but to the credit card company I've become your account." One major problem, experts say, is that the Social Security Number (SSN) — originally meant only for retirement benefit and tax purposes — has become the universal way to identify people. It is used as identification by the military, colleges and in billions of commercial transactions. Yet a shrewd thief can easily snatch your SSN, not only by stealing your wallet, but also by taking mail from your box, going through your trash for discarded receipts and bills or asking for it over the phone on some pretext. Using your SSN, the thief applies for a credit card in your name, asking that it be sent to a different address than yours, and uses it for multiple purchases. A couple of months later the credit card company, or its debt collection agency, presses you for payment. You don't have to pay the debt, but you must clean up your damaged credit record. That means getting a police report and copy of the erroneous contract, and then using them to clear the fraud from your credit report, which is held by a credit bureau. Each step can require a huge amount of effort. In the Collins' case, the clearance of the erroneous charges from their record required three years of poring over records and ＄6, 000 in solicitor's fees. In the meantime, they were denied a loan to build a vacation home, forced to pay cash for a new heating and cooling system, hounded by debt collectors, and embarrassed by the spectacle of having their home watched by investigators looking for the missing car. Of course, thousands of people are caught and prosecuted for identity theft. But it was only last year that Congress made identity theft itself a federal crime. That law set up a special government office to help victims regain their lost credit and to streamline police efforts by tracking cases on a national scale. Consumer advocates say this may help but will not address the basic problems, which, they believe, are causing the outbreak in identity theft: industry's rush to attract more customers by issuing instant credit, inadequate checking of identity, and too few legal protections for consumers personal information.

单选题{{B}}Text 4{{/B}} Elections often tell you more about what people are against than what they are for. So it is with the European ones that took place last week in all 25 European Union member countries. These elections, widely trumpeted as the world's biggest-ever multinational democratic vote, were fought for the most part as 25 separate national contests, which makes it tricky to pick out many common themes. But the strongest are undoubtedly negative. Europe's voters are angry and disillusioned-and they have demonstrated their anger and disillusion in three main ways. The most obvious was by abstaining. The average overall turnout was just over 45%, by some margin the lowest ever recorded for elections to the European Parliament. And that average disguises some big variations: Italy, for example, notched up over 70%, but Sweden managed only 37%. Most depressing of all, at least to believers in the European project, was the extremely low vote in many of the new member countries from central Europe, which accounted for the whole of the fall in turnout since 1999. In the biggest, Poland, only just over a fifth of the electorate turned out to vote. Only a year ago, central Europeans voted in large numbers to join the EU, which they did on May 1st. That they abstained in such large numbers in the European elections points to early disillusion with the European Union-as well as to a widespread feeling, shared in the old member countries as well, that the European Parliament does not matter. Disillusion with Europe was also a big factor in the second way in which voters protested, which was by supporting a ragbag of populist, nationalist and explicitly anti-EU parties. These ranged from the 16% who backed the UK Independence Party, whose declared policy is to withdraw from the EU and whose leaders see their mission as "wrecking" the European Parliament, to the 14% who voted for Sweden's Junelist, and the 27% of Poles who backed one of two anti-EU parties, the League of Catholic Families and Selfdefence. These results have returned many more Eurosceptics and trouble-makers to the parliament: on some measures, over a quarter of the new MEPS will belong to the "awkward squad". That is not a bad thing, however, for it will make the 'parliament more representative of European public opinion. But it is the third target of European voters' ire that is perhaps the most immediately significant, the fact that, in many EU countries, old and new, they chose to vote heavily against their own governments. This anti-incumbent vote was strong almost everywhere, but it was most pronounced in Britain, the Czech Republic, Germany, Poland and Sweden. The leaders of all the four biggest European Union countries, Tony Blair in Britain, Jacques Chirac in France, Gerhard Schroder in Germany and Silvio Berlusconi in Italy, were each given a bloody nose by their voters. The big question now is how Europe's leaders should respond to this. By a sublime (or terrible) coincidence, soon after the elections, and just as The Economist was going to press, they were gathering in Brussels for a crucial summit, at which they are due to agree a new constitutional treaty for the EU and to select a new president for the European Commissi6n. Going into the meeting, most EU heads of government seemed determined to press ahead with this agenda regardless of the European elections--even though the atmosphere after the results may make it harder for them to strike deals.

单选题{{B}}Text 4{{/B}} The Net success of "Lazy Sunday" represents a defining moment for the film and television business. Advances in digital video and broadband have vastly lowered the cost of production and distribution. Filmmakers are now following the path blazed by bloggers and musicians, cheaply creating and uploading their work to the Web. If it appeals to any of the Net's niches, millions of users will pass along their films through e-mail, downloads or links. It's the dawn of the democratization of the TV and film business--even unknown personalities are being propelled by the enthusiasm of their fans into pop-culture prominence, sometimes without even traditional intermediaries like talent agents or film festivals. "This is like bypass surgery,' says Dan Harmon, a filmmaker whose monthly L. A. -based film club and Web site, Channel 101, lets members submit short videos, such as the recent 70s' music mockumentary "Yacht Rock," and vote on which they like best. "Finally we have a new golden age where the artist has a direct connection to the audience;" The directors behind "Lazy Sunday" embody the phenomenon. When the shaggy-haired Samberg, 27, graduated from NYU Film School in 2001, he faced the conventional challenge or, crashing the gates Of Hollywood. With his two childhood friends Akiva Schaffer and Jorma Taccone, he came up with an unconventional solution: they started recording music parodies and comic videos, and posting them to their Web site, TheLonelyisland. com. The material got the attention of producers at the old ABC sitcom "Spin City", where Samberg and Taccone worked as low-level assistants; the producers sent a compilation to a talent agency. The friends got an agent, made a couple of pilot TV sketch shows for Comedy Central and Fox, featuring themselves hamming it up in nearly all the roles, and wrote jokes for the MTV Movie Awards. Even when the networks passed on their pilots, Samberg and his friends simply posted the episodes online and their fan base--at 40,000 unique visitors a month earlier this year--grew larger. Last August, Samberg joined the "SNL" cast, and Schaffer and Taccone became writers. Now they share an office in Rockefeller Center and "are a little too cute for everyone," Samberg says, "We are friends living our dream." Short, funny videos like "Lazy Sunday" happen to translate online, but not everything works as well. Bite-size films are more practical than longer ones; comedy plays better than drama. But almost everything is worth trying, since the tools to create and post video are now so cheap, and ad hoc audiences can form around any sensibility, however eccentric.
