单选题The "MyDoom" virus could presage a generation of computer attacks by organised gangs aiming to extract ransoms from online businesses, experts said yesterday. The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago. The "MyDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files. On Sunday they began sending automated queries to SCO's website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company's doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages. "You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, 'If you don't want this to happen again, here are our demands'." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It's not terrorism, but it is somebody who is obviously upset with SCO" SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn. Mr. Cluley said: "It might be that whoever is behind this will say to SCO, 'if you don't want the next one to target you, drop the lawsuit'." SCO has offered $250,000 (￡140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom. Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It's hard for law enforcement to track them down, because they're using machines owned by innocent people." A second variant of MyDoom will start attacking part of Microsoft's website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets.

单选题Called by many critics the greatest achievement of English lyrical poetry, this elegy was written upon the death of a fellow alumnus of Milton's, Edward King, who was drowned in the Irish Sea in 1637. A group of King's former schoolmates at Cambridge issued a commemorative volume titled Obsequies to the Memory of Mr. Edward King (1638). It was in this limited publication that Lycidas first appeared. Heretofore, of his great poems only Comus had been published, and that anonymously. Lycidas is not an expression of personal grief ( personal grief was to be eloquent in Milton's next important poem, the Latin Epitaphium Damonis), but rather a record of the thoughts that King's death evoked in the poet. King had written verses himself and had prepared himself for the Church. These two facts of the dead man's career form the basis for what Milton had to say. Outwardly the poem is written in the tradition of pastoral poetry, and more particularly in the tradition of the pastoral elegy as exhibited in the ancient Greek Lament for Bion by Moschus. The poet is spoken of as a shepherd. But Milton introduces the innovation of identifying the Christian idea of shepherd (pastor) as meaning priest. In a wonderful fusion of pagan and Christian tradition, Milton makes his elegy the occasion for a scathing attack on the corruptions of the clergy in his time, with parenthetical thrusts of scorn at his trivial contemporaries, the Cavalier poets. Samuel Johnson, who disliked all pastoral poetry, made the one outstandingly foolish judgment of his career, in dismissing Lycidas as a work of an. He said its "diction is harsh, the rhymes uncertain, and the numbers unpleasing, "--a testimony of the fact that Johnson was deaf to the refinements of English poetry at its subtlest, for Lycidas is an exquisite piece of music from the first line through the last. Moreover, Johnson was upset at the mingling of "trifling fictions" with "the most awful and sacred truths, such as ought never to be polluted with such irreverent combinations." That pronouncement can only mean that Johnson failed to grasp the noble idea at the center of the poem: Milton's definition of the high function of a poet.

单选题The old Volkswagen Beetle —"The Bug" — is making a comeback. People who own them are planning to keep them forever. People who don"t own them are paying high prices when they can find one for sale. It"s more remarkable when you realize that VW doesn"t even make them anymore! A spokesman for Volkswagen of America says there were about five million "Bugs" on American roads in 1977. That was the last year they were shipped to America. VW estimates that about four million of them are still running and running and running. Used car dealers say they can"t keep "Bugs" on their lots these days. They feel it"s because these cars have a history of reliable, inexpensive transportation. The cars average about 30 miles per gallon of gas. But all hasn"t been smooth going for the "Bugs". The heating system is poor. And since it travels very close to the ground, larger ears tend to splash it with winter"s snow and mud. Some in the safety field consider the Beetle as defenseless against heavier cars. But the National Highway Traffic Safety Administration has nothing that shows any problem with them at all.

单选题{{B}}Text 4{{/B}} Europe is desperate to succeed in business. Two years ago, the European Union's Lisbon summit Set a goal of becoming the world's leading economy by 2010. But success, as any new age executive coach might tell you, requires confronting the fear of failure. That is why Europe's approach to bankruptcy urgently needs reform. In Europe, as in the United States, many heavily indebted companies are shutting up shop just as the economy begins to recover. Ironically, the upturn is often the moment when weak firms finally fail. But America's failures have a big advantage over Europe's weaklings: their country's more relaxed approach to bankruptcy. In the United States the Chapter 11 law makes going bust an orderly and even routine process. Firms in trouble simply apply for breathing space from creditors. Managers submit a plan of reorganization to a judge, and creditors decide whether to give it a go or to come up with one of their own. Creditors have a say in whether to keep the firm running, or to liquidate it. If they keep it running, they often end up with a big chunk of equity, if not outright control. But shutting a bust European company is harder in two other ways. First, with no equivalent of Chapter 11, bankruptcy forces companies to stop trading abruptly. That damages the value of the creditors' potential assets, and may also cause havoc for customers. Second, a company that trades across the European Union will find that it has to abide by different bankruptcy laws in the 15 member states, whose courts and administrators may make conflicting and sometimes incompatible stipulations. The absence of provision for negotiations between companies and creditors increases the temptation for government to step in. When governments do not come to the rescue, the lack of clear rules can lead to chaos. As a result of all this, Europe's teetering firms miss the chance to become more competitive by selling assets to others who might manage them more efficiently. Their sickly American rivals survive, transformed, to sweep the field. An opportunity now exists to think again about Europe's approach to bankruptcy. The European Union is expected to issue a new directive on the subject in May. Germany has begun to update its insolvency law. And last year Britain produced a white paper saying that a rigid approach to bankruptcy could stifle the growth needed to meet Lisbon's goals.
