Topic 7：Air pollution 霧都與空氣污染
The cartoon vividly reveals the phenomenon of air pollution or the declineof air quality. Causes of this issue appears to be complicated and mixed： firstly， vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and people's living standard， more and more urban inhabitants own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally， household appliances widely used in cities also release a great amount of carbon dioxide gases， which further intensifies air pollution. Last but not least， many factories around the cities emit large quantities of untreated and poinsonous gases， which should also be responsible for the decline of air quality.
It is undeniable that air pollution will exert a detrimental impact on many aspects of people's life. For example， many diseases such cough，skin problems and lang cancer are mainly caused by it. Hence， it is about time that we should begin to take some measures to reverse the inexorable decline in the air quality. （167words）
此圖生動地揭示了空氣污染和空氣質量下降的現象。這個問題的原因顯得比較復雜：首先，機動車的尾氣排放是主要原因。隨著經濟的發(fā)展和人們生活水平的提高，越來越多的城市居民都擁有了自己的汽車，而更多地汽車勢必帶來大量的尾氣排放。其次，城市里廣泛使用的家用電器排放了大量的二氧化碳，這也進一步加劇了空氣污染。最后，城市周邊的很多的工廠，也每天向空氣中排放大量的未經處理的有毒氣體，這也導致了空氣質量的下降。
無可否認，空氣污染會對人們生活的諸多方面造成有害的影響。比如，類似咳嗽、皮膚病和肺癌等很多疾病就主要是由空氣污染造成的。因此，我們是時候開始采取一些行動來扭轉空氣質量的不可逆轉的下滑了。
