下面是一篇关于美国经济复苏的雅思阅读材料，这篇雅思阅读材料的主要内容是虽然美国的经济正在复苏，但是，美国人的信心仍然深陷在经济危机当中没有回复。在2月份的一次对于世界经济的领导力量的调查中，大多数人选择了中国。所以美国的经济复苏虽然充满了想法，但是还需付出实践。
Still full of ideas, but not making jobs
America needs to share the benefits of innovation more widely
THE economy is recovering, yet American confidence remains mired at levels more commonly seen in recessions. For that blame unemployment, petrol prices and a deeper, nagging feeling that America is in decline. A Gallup poll in February asked Americans to name the world’s leading economic power. By a significant margin, they said China.
Barack Obama has exploited this anxiety. America, he has said, faces a new “Sputnik moment” and must “compete for the jobs and industries of our time” by spending more on research, education and infrastructure. But the notion that America is on the verge of being vanquished by cleverer, more innovative competitors is flawed. First, competitiveness is a woolly concept that wrongly supposes countries, like football teams, win only when another team loses. But one country’s economic growth does not subtract from another’s. Second, America’s ability to innovate and raise productivity remains reasonably healthy. The problem is that the benefits of that innovation and productivity have become so narrowly concentrated that workers’ median wages have stagnated.
