　　话题解析：

　　近几年大家对环境资源话题非常关注，包括空气污染、雾霾、水资源短缺，但是四六级作文中都没有考过，今年同学们也引起重视。

        话题范文：

　　The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. What exactly contribute to this phenomenon? Possible 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 standard, 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.

　　此图生动地揭示了空气污染和空气质量下降的现象。到底是什么导致了这个现象?可能的理由罗列如下：首先，机动车的尾气排放是最主要的原因之一。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。

　　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.

　　很明显，空气污染会对人们生活的很多方面造成有害的影响。举例，很多诸如咳嗽、皮肤问题和肺癌这样的疾病都是由空气污染所引起的。或许我们是时候采取一些措施来处理空气污染这个问题了。
