Do or Die|生死一瞬间

Do or Die

by Marcus Maurice

Do you know what to do to survive a life or death situation?

  On a crisp February morning in 2013, residents of Chelyabinsk, Russia, were going about their daily lives when something spectacular happened. Out of the sky, a meteor came hurling at the Earth at 40,000 miles an hour. A humongous white streak appeared in the sky for about 30 seconds, and then the meteor blew up. Because many cars and trucks in Russia have cameras attached to their dashboards, there were numerous videos of this amazing phenomenon on YouTube within hours.

  As scientists know, Earth is bombarded with 150 tons of rock from outer space every day. The good news is that most of them are only the size of a grain of rice and burn up in the atmosphere. The bad news is that eventually, rocks that are bigger will get through and become meteorites. The meteor that people saw that fateful February morning in Russia could have turned Chelyabinsk into a wasteland. Instead, it blew up in the atmosphere in what is called an air burst, which had the energy of a small nuclear explosion and generated a deadly force known as a shock wave. Several minutes after the blast, the shock wave tore through the city, and there is even footage of schools having their windows blown out.

  Now imagine you see an air burst in the sky; what would you do next? In National Geographic Channel's Do or Die, viewers are given three options to see if they would know how to survive. The first is to lie down in a gutter to hide from the shock waves. The second is to duck and seek cover next to a building. The final option is to brace yourself next to a tree. Make sure to watch Do or Die this month to find out the answer.





  2013 年二月一个凉爽的早晨,俄罗斯车里雅宾斯克市的居民正做着他们的例行公事,这时惊人的事情发生了。有一颗流星以时速四万英里从天外飞来直击地球。一道巨大的白光出现在天空中约三十秒,接着这颗流星就爆炸了。由于俄罗斯的许多车子和卡车的仪表板上都附有摄影机,因此几个小时之内就有许多这场惊人现象的影片被放到 YouTube 上。
