问题     The city of Wuxi, in east China’s Jiangsu province, was hit by a serious ecological disaster this week. A large bloom of blue-green algae in Taihu Lake caused water quality to deteriorate severely. Despite the local water department’s attempts at mitigating the crisis, the water supply to a great number of households was contaminated, the water becoming putrid and very unpleasant to drink. Degradation of water quality led to tremendous inconvenience to local inhabitants. In response, the Wuxi city government used their website to tell residents to come together and surmount the crisis, which they described as a "natural disaster" .
    While it is crucial to help others in the face of a crisis, labelling the algae bloom a natural disaster was completely inaccurate. Taihu Lake has suffered from low water levels this year, and the weather has been hot— with little rain—all of which will have contributed to the algae bloom. However, the local government announced that "the water quality problem is in no way caused by manufacturing or any other human activity", when in fact there were local factors causing the algae bloom. In particular: the serious eutrophication of Taihu Lake, caused by the great volume of pollutants discharged into the water.

选项

答案 中国东部江苏省的无锡市本周正在经历一场严重的生态灾难。太湖蓝藻大面积暴发,造成饮用水源地水质恶化。尽管供水部门采取了各项补救措施,千家万户的自来水龙头出水依然腥臭难闻,难以饮用。供水水质下降给居民的生活带来了极大不便。无锡市政府通过其网站提请广大市民,面对自然灾害,要同舟共济、克服困难、共渡难关。 “同舟共济,共渡难关”应该是这个艰难时刻的主旋律,但将蓝藻暴发归结为自然灾害则非常不妥。的确,今年无锡区域内的太湖出现低水位,同时天气连续高温少雨,这些都是蓝藻暴发的诱因,当地政府因此宣称“水质问题并不是生产或其他人为因素造成的”。但是,实际上,蓝藻暴发是由当地因素导致的,尤其是太湖水体严重富营养化。而太湖水体的富营养化则是污染物质大量排人造成的结果。
