Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979-80, when they also almost tripled. Both previous shocks resulted in double digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time?The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980.On the other hand, oil-importing emerging economies to which heavy industry has shifted have become more energy intensive, and so could be more seriously squeezed.One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economists commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.1.The main reason for the latest rise of oil price is ( ).2.It can be inferred from the text that the retail price of petrol will go up dramatically if ( ).3.The estimates in Economic Outlook show that in rich countries ( ).4.We can draw a conclusion from the text that ( ).5.From the text we can see that the writer seems( ).
Traditionally, the study of history has had fixed boundaries and focal points ——periods, countries, dramatic events, and great leaders. It also has had clear and firm notions of scholarly procedure: how one inquires into a historical problem, how one presents and documents one's findings, what constitutes admissible and adequate proof.Anyone who has followed recent historical literature can testify to the revolution that is taking place in historical studies. The currently fashionable subjects come directly from the sociology catalog: childhood, work, leisure. The new subjects are accompanied by new methods. Where history once was primarily narrative, it is now entirely analytic. The old questions “What happened?" and "How did it happen?" have given way to the question “Why did it happen?" Prominent among the methods used to answer the question "Why" is psychoanalysis, and its use has given rise to psychohistory.Psychohistory does not merely u
As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an even earlier age. This isn’t the stuff of gloomy philosophical contemplations, but a fact of Europe’s new economic landscape, embraced by sociologists, real-estate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the “irresistible momentum of individualism” over the last century. The communications revolution the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on(扰乱)European’s private lives.Europe’s new economic climate has largely fostered the trend toward independence. The current generation of home-aloners came of age during Europe’s shift from social democracy to the sharper, more individualistic climate of American-style capitalism. Raised in an era of privatization and increased consumer choice, today’s tech-savvy (精通技术的)workers have embraced a free market in love as well as economics. Modern Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so.Once upon a time, people who lived alone tended to be those on either side of marriage — twenty something professionals or widowed senior citizens. While pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful and strong! Now, young people want to live alone.The booming economy means people are working harder than ever. And that doesn’t leave much room for relationships. Pimpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn’t got time to get lonely because he has too much work. “I have deadlines which would make life with someone else fairly difficult.” Only an ideal woman would make him change his lifestyle, he says. Kaufrnann, author of a recent book called “The Single Woman and Prince Charming,” thinks this fierce new individualism means that people expect more and more of mates, so relationships don’t last long if they start at all. Eppendorf a blond Berliner with a deep tan, teaches grade school in the mornings. In the afternoon she sunbathes or sleeps, resting up for going dancing. Just shy of 50, she says she’d never have wanted to do what her mother did give up a career to raise a family. Instead, “I’ve always done what I wanted to do: live a self-determined life.”
