考研英语作文 预测：雾都
Topic 7：Air pollution 雾都与空气污染
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）
此图生动地揭示了空气污染和空气质量下降的现象。这个问题的原因显得比较复杂：首先，机动车的尾气排放是主要原因。随着经济的发展和人们生活水平的提高，越来越多的城市居民都拥有了自己的汽车，而更多地汽车势必带来大量的尾气排放。其次，城市里广泛使用的家用电器排放了大量的二氧化碳，这也进一步加剧了空气污染。最后，城市周边的很多的工厂，也每天向空气中排放大量的未经处理的有毒气体，这也导致了空气质量的下降。
无可否认，空气污染会对人们生活的诸多方面造成有害的影响。比如，类似咳嗽、皮肤病和肺癌等很多疾病就主要是由空气污染造成的。因此，我们是时候开始采取一些行动来扭转空气质量的不可逆转的下滑了。
