问题    If you want to know why Denmark is the world’s leader in wind power, start with a three-hour car trip from the capital Copenhagen to the small town of Lem on the far west coast of Jutland. You’ 11 feel it as you cross the 6.8 km-long Great Belt Bridge: Denmark’s bountiful wind, so fierce. But wind itself is only part of the reason. In Lem, workers in factories the size of aircraft hangars build the wind turbines. Most impressive are the turbine’s blades, which scoop the wind with each sweeping revolution.
   But technology, like the wind itself, is just one more part of the reason for Denmark’s dominance. In the end, it happened because Denmark had the political and public will to decide that it wanted to be a leader—and to follow through. Beginning in 1979, the government began a determined programme of subsidies and loan guarantees to build up its wind industry. It also mandated that utilities purchase wind energy at a preferential price—thus guaranteeing investors a customer base.
   As a result, wind turbines now dot Denmark. The country gets more than 19% of its electricity from the breeze and Danish companies control one-third of the global wind market, earning billions in exports and creating a national champion from scratch.
   The challenge now for Denmark is to help the rest of the world catch up. With Copenhagen set to host all-important U.N. climate change talks in December—where the world hopes for a successor to the expiring Kyoto Protocol, Denmark’s example couldn’t be more timely. "We’ ll try to make Denmark a showroom," says Prime Minister Anders Fogh Rasmussen. "You can reduce energy use and carbon emissions, and achieve economic growth."
   It’ s tempting to assume that Denmark is innately green, but the country’ s policies were actually born from a different emotion, one now in common currency: fear. When the 1973 oil crisis hit, 90% of Denmark’s energy came from petroleum, almost all of it imported. Denmark launched a rapid drive for energy conservation. Eventually the Danes themselves began enjoying the benefits of the petroleum and natural gas in their slice of the North Sea. It was enough to make them more than self-sufficient. But Denmark never forgot the lessons of 1973, and kept driving for greater energy efficiency and a more diversified energy supply.
   To the rest of the world, Denmark has the power of its example, showing that you can stay rich and grow green at the same time. "Denmark has proven that acting on climate can be a positive experience, not just painful." says NRDC’ s Schmidt.
According to Paragraph 5, Denmark’ s energy-saving policies traced back to the country’ s_____.

选项 A、environmental awareness
B、past experience of oil shortage
C、great shortage of natural resources
D、abundance in wind resources

答案B

解析 根据题干关键词定位到文章第五段。第五段首句指出,丹麦是由于恐惧而致力于推行节能环保政策。而他们的这种忧患心理正是由1973年的石油危机激发出来的,因此B项“该国过去石油短缺的经验”符合题意。通过第五段第四句the Danes themselves began enjoying the benefits of the petroleum and natural gas in their slice of the North Sea可知,丹麦的自然资源并不匮乏,故C项“该国自然资源的匮乏”表述错误。A项“环保意识” 和D项“这个国家的风能资源丰富”均不符合题意,故选B。
