答案：A
[试题分析]文章主旨题。
[详细解答]题干要求考生识别文章的中心思想，即“我们能从文章中得出什么结论”。文章一开始提出最近石油价格大幅上涨，会不会像前两次油价暴涨一样造成经济衰退。但接下来它又说这次油价上涨的影响不会像以前那样严重，并说出了几点原因：(1)原油价格只占汽油价格的一小部分，(2)发达国家对石油的依赖性不如从前，(3)并没有同时发生商品总价格上涨和全球需求旺盛的现象。因此，文章的中心思想是A选项“oil-price shocks are less shocking now”(现在的油价暴涨并不可怕)。B选项“iafla tion seems irrelevant to oil-price shocks”(通货膨胀与油价暴涨无关)，C选项"energy conservation can keep down the oil prices"(能源储备能够压抑油价)和D选项“the price rise of crude leads to the shrinking of heavy industry”(原油价格上涨导致重工业的萎缩)都不是全文重点讨论的内容。
