        Recently, the 2014 Beijing international marathon held under the impetus of the national fitness strategy smoothly, pomp. Participants of eager more than in the past, applicants need through a lottery to occupy one seat, even unprecedented. However, everything all has the duality, the tournament's most unfortunately, the contestants notting have is not running in haze weather, won the legs, but lost the lungs. 
 
        As we all know, sunshine, water and air is fundamental to the survival of life material, if the lack of sunlight and water also can maintain to sustain life, the air is indispensable to moment.
