问题     The dawn of the oil age was fairly recent. Although the stuff was used to waterproof boats in the Middle East 6,000 years ago, extracting it in earnest began only in 1859 after an oil strike in Pennsylvania. It was used to make kerosene, the main fuel for artificial lighting after overfishing led to a shortage of whale blubber. Other liquids produced in the refining process, too unstable or smoky for lamplight, were burned or dumped. But the unwanted petrol and diesel did not go to waste for long, thanks to the development of the internal-combustion engine a few years later.
    Since then demand for oil has, with a couple of blips in the 1970s and 1980s, risen steadily alongside ever-increasing travel by car, plane and ship. Three-fifths of it ends up in fuel tanks. With billions of Chinese and Indians growing richer and itching to get behind the wheel of a car, the big oil companies, the International Energy Agency(IEA)and America’s Energy Information Administration all predict that demand will keep on rising.
    We believe that they are wrong, and that oil is close to a peak. This is not the "peak oil" widely discussed several years ago, when several theorists, who have since gone strangely quiet, reckoned that supply would flatten and then fall. We believe that demand, not supply, could decline. In the rich world oil demand has already peaked: it has fallen since 2005. Even allowing for all those new drivers in Beijing and Delhi, two revolutions in technology will dampen the world’s thirst for the black stuff.
    The first revolution was led by a man from Texas who has just died. George Mitchell championed "tracking" as a way to release huge supplies of "unconventional" gas from shale(a smooth soft rock)beds. This, along with vast new discoveries of conventional gas, has recently helped increase the world’s reserves from 50 to 200 years. The other great change is in automotive technology. Rapid advances in engine and vehicle design also threaten oil’s dominance. Foremost is the efficiency of the internal-combustion engine itself. Petrol and diesel engines are becoming ever more frugal.
    Not surprisingly, the oil "supermajors" and the IEA disagree. They point out that most of the emerging world has a long way to go before it owns as many cars, or drives as many miles per head, as America. But it would be foolish to predict from the rich world’s past to booming Asia’s future. The sorts of environmental policies that are reducing the thirst for fuel in Europe and America by imposing ever-tougher fuel-efficiency standards on vehicles are also being adopted in the emerging economies.
Which of the following statements is true, according to paragraph 3 and 4?
选项 A、Demand for oil is close to a peak with supplies increased.
B、The oil demand in the world has already peaked until 2005.
C、New energy has broken the dominance of conventional gas.
D、Demand for oil is limited while supply of oil is unlimited.
答案A
解析 第三段第1句作者指出石油公司和其他机构的错误预测。作者认为石油已经接近峰值(be closeto a peak)，然后是进一步的解释，其中提到石油需求将下降，而不是石油供应，接着第四段第3旬指出石油开采技术的革命增加了石油储备(helped increase the world’s reserves)，可见A项的表述是正确的。
