Premature 的意思是尚未成熟、为时过早的。 South Korean officials think it is premature to tell whether the recent activity at some of the rocket facilities in North Korea involved preparation for a missile launch. 韩国官员认为，现在就谈论朝鲜某些火箭设施的近期活动是否与准备发射导弹有关还为时过早。

 

Environmental monitoring groups said in a recent report that air pollution is the greatest environmental risk to health today, estimating it contributes to 7 million premature deaths every year. 环境监测组织在最近的一份报告中表示，空气污染是当今对人身健康的最大环境风险，估计每年造成700万人过早死亡。
