问题                                         Are We Ready For An Asteroid Impact?
    This October, NASA will conduct a drill to see how well its planetary defense system would work if an actual asteroid were heading straight for Earth. While these sort of drills have been done in the past with pretend asteroids, this one will feature a real asteroid, one that astronomers are confident will miss the Earth as it zooms by Oct. 12.
    "The question is: How prepared are we for the next cosmic threat?" said Vishnu Reddy of the University of Arizona, a NASA consultant. "So we wanted to test how ready we are for a potential impact by a hazardous asteroid. "

选项

答案 面对小行星撞击,我们是否已准备就绪? 今年10月,美国国家航空航天局将进行一次演习,测试一颗真正的小行星径直撞向地球的情况下其小行星防御系统的表现。虽然过去也曾进行过类似演习,不过对象皆为模拟小行星,而这次演习的对象却是一颗真正的小行星。天文学家确信,这颗小行星将于10月12日与地球擦肩而过。 就职于亚利桑那大学的美国宇航局顾问维施努.莱迪说:“问题在于:面对下一个来自宇宙的威胁,我们是否已准备就绪?因此,我们希望借此次演习,测试在面对有潜在撞击地球危险的小行星时,我们的准备情况。”

解析     这句话介绍了以往进行过的类似演习与本次演习的区别。通过分析可知,this one will feature a real asteroid是本句主干,句中转折连接词while:表达对比的含义,翻译时使用“虽然……不过……而……”,以突出这种逻辑联系。“one that…”这部分为同位语,是对先行词a real asteroid的进一步解释说明,由于前文内容信息量较大,所以另起一句介绍,会令句子结构更清晰。zoom by表示“疾驰而过”,miss表示“错过”,miss the Earth as it zooms by描述了小行星擦地球而过的状态,使用四字词语“擦肩而过”,语言较生动。
