今天北京的霧霾非常大，現在窗外的能見度非常低，霧霾的圖片刷爆了朋友圈。那麼"霧霾"用英語怎麼說呢？我們一起來學習吧！
"霧霾"這個詞大家一定不會陌生，早在今年年初，柴靜的《穹頂之下》講述的故事就與霧霾相關，當時BBC官網還專門寫了一篇文章報導了此事：
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
不難看出，"霧霾"對應的英語是
smog它是smoke與fog的合成詞，也即smoke + fog → smog，所以說霧霾是煙塵與霧氣的結合體。高中我是化學科代表，還清晰地記得老師強調過，"煙是固體小顆粒而霧是小液滴"。因此，霧霾既含有如工廠中的燃燒過程產生的固體小顆粒，又含有水汽。
【例】Cars cause pollution, both smog and acid rain. 車輛會導致汙染，包括霧霾與酸雨。

smog的形容詞是smoggy（注意雙寫g），也即"有霧霾的"。
【例】Mexico City is one of the world's smoggiest capitals. 墨西哥城是世界上霧霾最嚴重的首都城市之一。

smog這一詞最初是用來指倫敦的霧霾的，以下資料供大家參考：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, 搵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.?
