单选题Plato asked "What is man?" and St Augustine asked "Who am I?' A new breed of criminals has a novel answer: "I am you!" Although impostors have existed for ages, the growing frequency and cost of identity theft is worrisome. Around 10m Americans are victims annually, and it is the leading consumer-fraud complaint over the past five years. The cost to businesses was almost $50 billion, and to consumers $5 billion, in 2002, the most recent year that America's Federal Trade Commission collected figures. After two recent, big privacy disasters, people and politicians are calling for action. In February, ChoicePoint, a large data-collection agency, began sending out letters warning 145,000 Americans that it had wrongly provided fraudsters with their personal details, including Social Security numbers. Around 750 people have already spotted fraudulent activity. And on February 25th, Bank of America revealed that it lost data tapes that contain personal information on over lm government employees, including some Senators. Although accident and not illegality is suspected, all must take precautions against identity theft. Faced with such incidents, state and national lawmakers are calling for new regulations, including over companies that collect and sell personal information. As an industry, the firms—such as ChoicePoint, Acxiom, LexisNexis and Westlaw—are largely unregulated. They have also grown enormous. For example, ChoicePoint was founded in 1997 and has acquired nearly 60 firms to amass databases with 19 billion records on people. It is used by insurance firms, landlords and even police agencies. California is the only state, with a law requiring companies to notify individuals when their personal information has been compromised—which made ChoicePoint reveal the fraud (albeit five months after it was noticed, and after its top two bosses exercised stock options). Legislation to make the requirement a federal law is under consideration. Moreover, lawmakers say they will propose that rules governing credit bureaus and medical companies are extended to data-collection firms. And alongside legislation, there is always litigation. Already, ChoicePoint has been sued for failing to safeguard individuals' data. Yet the legal remedies would still be far looser than in Europe, where identity theft is also a menace, though less frequent and costly. The European Data Protection Directive, implemented in 1998, gives people the right to access their information, change inaccuracies, and deny permission for it to be shared. Moreover, it places the cost of mistakes on the companies that collect the data, not on individuals. When the law was put in force, American policymakers groaned that it was bad for business. But now they seem to be reconsidering it,

单选题Whenever you see an old film, even one made as little as ten years ago, you cannot help being struck by the appearance of the women taking part. Their hair-styles and make-up look dated; their skirts look either too long or too short; their general appearance is, in fact, slightly ludicrous. The men taking part in the film, on the other hand, are clearly recognizable. There is nothing about their appearance to suggest that they belong to an entirely different age. This illusion is created by changing fashions. 1 The same cannot be said for women. Each year a few so-called top designers in Paris or London lay down the law and women over the whole world rush to obey. The decrees of the designers are unpredictable and dictatorial. This year they decide in their arbitrary fashion, skirts will be short and waists will be high; zips are in and buttons are out. Next year the law is reversed and far from taking exception, no one is even mildly surprised. If women are mercilessly exploited year after year, they have only themselves to blame. 2 Clothes, which have been worn, only a few times have to be discarded because of the dictates of fashion. When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear. 3 Many women squander vast sums of money each year to replace clothes that have hardly been worn. Women, who cannot afford to discard clothing in this way, waste hours of their time altering the dresses they have. Hem-limes are taken up or let down; waist-lines are taken in or let out; neck-lines are lowered or raised, and so on. 4 Fashion designers are rarely concerned with vital things like warmth, comfort and durability. They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, providing they look right. There can hardly be a man who hasn"t at some time in his life smiled at the sight of a woman shivering in a flimsy dress on a wintry day, or delicately picking her way through deep snow in dainty shoes. 5 Do the constantly changing fashions of women"s clothes, one wonders, reflect basic qualities of fickleness and instability? Men are too sensible to let themselves be bullied by fashion designers. Do their unchanging styles of dress reflect basic qualities of stability and reliability? That is for you to decide. A.Changing fashions are nothing more than the deliberate creation of waste.B.No one can claim that the fashion industry contributes anything really important to society.C.The difference between men and women in the matter of fashion is fascinating.D.Over the year, the great majority of men have successfully resisted all attempts to make them change their style of dress.E.Because they shudder at the thought of being seen in public in clothes that are out of fashion, they are annually black-mailed by the designers and the big stores.

单选题Passage One The increase in leisure time, the higher standard of living, the availability of cars to a wider range of the population and, perhaps, a broadening of personal horizons have all contributed to a drastic change in the summer week-end habits of the British publiC. Now, on most Saturdays in the months loosely called summer, it is possible to see family saloons loaded with picnics and crammed to bursting with several generations of pleasure-bent Smiths'. Like competitors in some grossly disorganized rally, they nose their way through the neat drab streets of council estates, converging on the main roads, then crawl as best they can out into the open country and towards the coast. Congestion and the frustration of wasting precious time at the receiving end of someone else's exhaust fumes gets the pursuit of enjoyment off to had start; tempersbecome frayed. Children, traditionally the target for fathers' ill-humor, are singled out for special treatment. The past week's misdeeds are unearthed and magnified out of all reasonable proportion; mothers leap to their broods' defense and, before long, vows that never again will this outing be repeated are being hurled back and forth. Of course, by this time, the children have wisely extracted themselves from the argument and are quietly amusing themselves by looking at their irate elders or gaping at the unfamiliar sight of animals in fields, often so much stranger to them than the corresponding naked shapes they are wont to see in butchers' windows. Eventually, tempers partially restored, the sea is in sight. The paraphernalia of enjoyment is set up on teeming beach, sand mysteriously appears in every sandwich, pale industrial legs are exposed in self-conscious nakedness. The children drift away, quite capable of finding enough magic in this exciting, watery world to occupy them fully until they are gathered in again. Fathers and mothers, and quite possibly some members of a previous generation, settle back to receive the sun and dream away the tensions brought to a climax by the journey. Fathers eye with furtive lustfulness and mothers glare with disapproval and envy as the shapely matrons of tomorrow splash and play and race coquettishly around them, spraying water and sand and disturbing any hopes of peace. At length the shadows drop and chill in the air brings an end to the idyll. The lobster skin is painfully covered up and the day's debris half-heartedly collected. The family is rounded up and the brief dreams trodden into the sand along with the wasted paper.

单选题{{B}}Passage 3{{/B}} In the long run a government will always encroach upon freedom to the extent to which it has the power to do so. This is almost a natural law of politics, since, whatever the intentions of the men who exercise political power, the sheer momentum of government leads to a constant pressure upon the liberties of the citizen. But in many countries society has responded by throwing up its own defenses in the shape of social classes or organized corporations which, enjoying economic power and popular support, have been able to set limits to the scope of action of the executive. Such, for example, in England was the origin of all our liberties--won from government by the stand first of the feudal nobility, then of churches and political parties, and latterly of trade unions, commercial organizations, and the societies for promoting various causes. Even in European lands which were arbitrarily ruled, the powers of the monarchy, though absolute in theory, were in their exercise. checked in a similar fashion. Indeed the fascist dictatorships of today are the first truly tyrannical governments which western Europe has known for centuries, and they have been rendered possible only because on coming to power they destroyed all forms of social organization which were in any way rivals to the state.
