模仿文本：  One regional economy that doesn't have to worry about making ends meet is Libya. Oil and gas account for more than 80% of its annual economic output and for almost all of Libya's export revenues. That means, of course, it's done very well out of the recent high oil price. But it also leaves Libya very vulnerable. Oil prices, as we well know, fluctuate sharply. So what else does the economy there have to offer?

译文： 利比亚就无需担心它的经济入不敷出。石油和天然气产量占到了年度经济产出的80%以上，这也几乎是利比亚全部的出口收入。当然这意味着在最近高油价的行情下，利比亚确实做得很好。但这也显露了它的弱点。因为我们知道，油价极易波动。那么利比亚要生存下去还需要什么呢？
