北京市环保局的一份报告显示，自8月20日起，北京PM2.5浓度连续保持一级优，媒体称这段时间的蓝天为“阅兵蓝”。

【讲解】

文中的parade blue就是“阅兵蓝”的意思，“阅兵蓝”的说法源于去年11月初的“APEC蓝”(APEC blue)，由于采取了一系列减排措施，包括周边城市工厂停产(suspend production by factories in neighboring cities)，限制演练区域的交通流(traffic flow)等，北京出现了蓝天白云。

最后一句中的shut down是动词短语，表示“(使工厂、公司等)关闭，歇业，停业”，如：Smaller contractors have been forced to shut down.(规模较小的承包商已被迫歇业。)
