雾霾的英文作文

　　A group of Edinburgh medical students dugup the facts on the Great London Smog of 1952 (the photos are fascinating; areal shock for people who think environmental problems are something new).

　　几位爱丁堡大学医学院的学生发掘了1952年伦敦大雾霾的`一些事实(其中的照片引人入胜;这对于那些认为环境问题历史甚短的人无疑是当头棒喝)。这些学生提供了1952年伦敦空气污染水平的一批数字，我把它们与北京的最近数字做了比较。

　　Beijing’s poor airquality – 300 or somicrograms of particulate matter per cubic metre – has generated volumesof purple prose, but London’s numbers in the 1950s were consistently above 400, and surged to 1,600 during theGreat Smog – more than five times Beijing’s inearly August.

　　北京上空每立方米空气约含300微克粉尘物质，这一恶劣的空气质量已经让人写出了许多华丽的抱怨文章，但伦敦在1950年代的这一数字持续超过400，并在大雾霾期间狂涨到1600，这是北京八月初数字的5倍以上。
