"Smoke contains toxic gases, narcotic gases. It contains irritant gases. If you inhale enough of them you will die," explains Galea. He carries a smoke hood but warns that if you`re going to follow his example you must learn how to use it. Otherwise you`ll waste time trying to put it on — time that could be used for making an exit. “烟雾含有有毒麻醉气体，并带有强烈刺激性。过多吸入将导致死亡。”盖里尔教授解释道。他在旅行中会携带一个防烟头罩，但他警告说，想像他这样，就要学会如何使用该头罩。否则会为戴上它而耽误你逃生的最佳时机。 来源:可可英语 http://www.kekenet.com/read/201403/279607.shtml
