阅读理解 A couple of years ago, those who forecast that oil price would reach $ 100 a barrel were seen as doomsters. However, now some are predicting $ 200 a barrel.
Had economists been told that oil price would barely pause at $ 100 before reaching the recent peak of nearly $ 127, they would no doubt have forecast terrible economic consequences. But the global economy, though interrupted by the high price of energy, is still chugging along. Meanwhile, inflation has picked up, but the headline rates of inflation (通货膨胀率) in most developed countries are nowhere near the levels seen in the 1970s and 1980s.
There are three explanations for the oil price’s unclear impact. The first is that nowadays developed economies are more efficient in their use of energy, thanks partly to the increased importance of service industries and the diminished role of manufacturing(制造业). According to the Energy Information Administration, the energy intensity of America’s GDP fell by 42% between 1980 and 2007.
A second theory is that the oil-price rise has been steady, not sudden, giving the economy time to adjust. Giovanni Serio of Goldman Sachs points out that in 1973 there was a severe supply shock because of the oil embargo(石油禁运), when the world had to cope with 10%-15% less crude almost overnight. Not this time.
The third explanation turns the argument on its head; rather than oil harming the global economy, it is global expansion that is driving up the price of oil.
The most important factor is the shift in favor of the developing economies. America has responded to high price in familiar fashion: UBS forecasts that demand will drop by 1.1% this year and will be no higher in 2010 than it was in 2004. But the demand from China and other emerging markets is more than offsetting(抵消) this shortfall.1.What is the passage mainly talking about?A.The prediction of economistsB.The situation of economyC.The increase of oil priceD.The American response to high price2.How many explanations for the oil price’s impact are mentioned in the passage?A.TwoB.ThreeC.FourD.Five3.What can we conclude from the passage?A.In USA, the demand for oil in 2010 will be very highB.In USA, the demand for oil in 2010 will be higher than it was in 2004C.In USA, the demand for oil in 2010 will be as high as it was in 2004D.In USA, the demand for oil in 2010 will be as low as it was in 2004
