The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. What exactly contribute to this phenomenonPossible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and people’s living stand

　　ard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great mount of carbon dioxide gases, which further

　　intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.

　　Definitely, air pollution will exert a detrimental impact on many aspects of people’s life. For example, many diseases such as cough, skin problem and lang cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.

　　此圖生動地揭示了空氣污染和空氣質量下降的現象。到底是什么導致了這個現象可能的理由羅列如下：首先，機動車的尾氣排放是最主要的原因之一。隨著經濟的發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。

　　很明顯，空氣污染會對人們生活的很多方面造成有害的影響。舉例，很多諸如咳嗽、皮膚問題和肺癌這樣的疾病都是由空氣污染所引起的。或許我們是時候采取一些措施來處理空氣污染這個問題了。
