这是一道涉及对全文主旨理解的考题。综合全文，作者对美国经济进行了客观、全面的分析。从第二至四段的内容可知，作者对GDP的增长原因、经济对劳动市场的影响、美联储提高利率的措施都持有谨慎的乐观态度。但是作者也指出失业的速度有所缓和（三段末），美联储的货币政策相对中性化（四段末），工业生产部门的产量正在达到底线，复苏即将开始（第五段），办公设备部门将以比较缓和的速度继续增长（第九段末）。因此［B］项恰当地概括了美国的经济形势。
文章开篇就提到，政府报告带来的意外惊喜使经济学家对国民生产总值的预测上调。排除［A］项。首段提到，有观点认为经济衰退期已在12月或1月终止。但下文只描述了经济的复苏趋势，因此［C］项不符合。［D］项错在surprisingly fast pace，文中大量出现表示“适中、温和”含义的关键词，如tame，neutrality，relaxed pace等，表明经济的发展速度是缓慢的。
