课文朗读
A meteoroid entered the Earth’s atmosphere and exploded over the Ural Mountains in southern Russia earlier this year. The estimated 12-meter object traveled at about 18 km/s before breaking apart 15-25 km above the ground. It exploded with a force of approximately 30 times the energy of the Hiroshima atomic bomb. Fortunately, no one died from being hit by the meteoroid.
今年年初，一枚流星体进入地球的大气层，并在俄罗斯南部的乌拉尔山脉上空爆炸。这枚估计约15公尺长的物体，在距离地面15到25公里上方炸裂前，以秒速约18公里行进。它的爆炸威力粗估是广岛原子弹能量的30倍。幸运的是无人死于流星体撞击。
However, the mid-air explosion created a shock wave that damaged around 3,000 buildings and hurt more than 1,000 people. Most wounds were the result of shattered glass. In Chelyabinsk, a city near the Ural Mountains, office buildings were emptied and classes for all schools were canceled that day for safety.
然而，半空中的爆炸产生冲击波，损坏约3千栋建筑物，并使超过千人受伤，而大部分伤口是由飞散的碎玻璃造成。在乌拉尔山脉邻近的城市车里亚宾斯克，当天使所有人员撤出办公大楼，学校也停课以策安全。
Within a couple of hours the Russian government confirmed the incident, and sent rescue workers to help the victims. Prime Minister Dmitry Medvedev said the event proves the Earth’s vulnerability to meteorite impact. On the day of the explosion, the United Nations Office for Outer Space Affairs proposed a warning system for monitoring near-Earth objects in the future.
数小时内俄罗斯政府证实这项事件，并派救难人员协助伤员。俄罗斯总理麦德维夫表示：此事件显示地球对于陨石撞击有其难以招架的脆弱性。爆炸发生当天，联合国外层空间事务处提议建造警示系统，以监控未来接近地球的星体。
