The thick nitrogen atmosphere holds fog, mist, smoggy haze and rain clouds.

　　厚厚的氮氣組成的大氣層你彌漫著煙霧和云。

　　The result has been more blue - sky days during the Olympics than smoggy ones.

　　結果就是奧運會期間藍天白云比煙霧蒙蒙的時候更多了。

　　That said, it's obviously no cure-all for those living under China's smoggy skies.

　　但話又說回來，對于生活在中國霧霾空氣中的人們，顯然并不存在解決這一問題的靈丹妙藥。
