今天北京的雾霾非常大，现在窗外的能见度非常低，雾霾的图片刷爆了朋友圈。那么"雾霾"用英语怎么说呢？我们一起来学习吧！
　　"雾霾"这个词大家一定不会陌生，早在今年年初，柴静的《穹顶之下》讲述的故事就与雾霾相关，当时BBC官网还专门写了一篇文章报道了此事：
　　Under the Dome: The smog film taking China by storm
　　By Celia Hatton
　　BBC News, Beijing
　　2 March 2015
　　CCTV's offices shrouded in smog - the organisation said Ms Chai shot the film independently
　　不难看出，"雾霾"对应的英语是
　　smog
　　它是smoke与fog的合成词，也即smoke + fog → smog，所以说雾霾是烟尘与雾气的结合体。高中我是化学科代表，还清晰地记得老师强调过，"烟是固体小颗粒而雾是小液滴"。因此，雾霾既含有如工厂中的燃烧过程产生的固体小颗粒，又含有水汽。
　　【例】Cars cause pollution, both smog and acid rain. 车辆会导致污染，包括雾霾与酸雨。

　　smog的形容词是smoggy（注意双写g），也即"有雾霾的"。
　　【例】Mexico City is one of the world's smoggiest capitals. 墨西哥城是世界上雾霾最严重的首都城市之一。

　　smog这一词最初是用来指伦敦的雾霾的，以下资料供大家参考：
　　New phenomena require new words, so it is not surprising that smog is a relatively recent coinage. The word followed the phenomenon by perhaps half a century, for air pollution was first noticed during the Industrial Revolution. The word smog is first recorded in 1905 in a newspaper report of a meeting of the Public Health Congress. Dr. H.A. des Vux gave a paper entitled 揊og and Smoke,?in which, in the words of the Daily Graphic of July 26, 揾e said it required no science to see that there was something produced in great cities which was not found in the country, and that was smoky fog, or what was known as 憇mog.挃 The next day the Globe remarked that 揇r. des Vux did a public service in coining a new word for the London fog.?
