the National Environmental Protection Agency

In its first ever National building Competition, the U.S. Environmental Protection Agency challenged teams from across the nation to cut wasteful energy use in buildings in which they live and work.

在首届全国建筑竞赛上，美国环保署要求来自全国各地的参赛小组最大幅度地降低人们工作和生活于其中的建筑的能源浪费。

Last year, a report by the U. S. National Research Council agreed that ozone exposure could kill and urged the Environmental Protection Agency (EPA) to conduct more studies of ozone-related mortality.

去年，美国国家研究理事会的一篇报道承认：暴露于臭氧中可能会置人于死地，并催促美国环保局进行更多跟臭氧相关的死亡情况研究。
