英国陷入了二次探底，关于衰退的定义，连续两个季度出现收缩，有些武断，也没有参考意义。请看相关英文报道：The UK is in a double-dip recession and the definition of recession – two consecutive quarters of contraction – is arbitrary and unhelpful.分析：在上述报道中，"double-dip recession"就是“二次探底”的意思。 温总理曾经在答记者会上说过，经济发展要预防二次探底，因为相比第一次经济衰退来说，二次探底的风险更大，对经济复苏造成的影响也就更大。各种“衰退”的英语表达：1.衰退：recessionEconomists fear a similar wave of protectionism today could plunge the world back into recession.经济学家担心类似的保护主义会使得世界经济再次衰退。2.不景气：downturnHeavy labor taxes are one reason why Europe entered the downturn with far higher unemployment than America.高额的劳动力税是欧洲以比美国更高的失业率步入衰退的原因之一。3.暴跌：meltdownIf 2008 was the year of the banking meltdown, then 2009 was the year of the stimulus packages.如果2008年是银行彻底垮台的一年，那么2009年就是一篮子刺激政策的一年。4.下挫：slumpThis would return the economy into a slump.这将使美国经济再次陷入衰退。5.下滑：declineMany Greeks believe they are caught up in a cycle of decline.很多希腊人相信他们正处于一轮下降周期之中。
