Question

This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again. 
It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic(地形学的) factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions(排放). But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country's power plants are located in the eastern region and China's coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world's total coal consumption. And with coal occupying nearly 70 percent of the country's primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation's overall air pollution problem.
In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on.
However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier. 
This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority(优先权)given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity(能力) fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation. 
Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth

试题分析：
本文介绍了中国空气污染的情况，分析了造成污染的原因，提出解决污染问题的对策措施。造成污染的原因主要是燃煤和汽车排放，燃煤是最大原因；而根源却在于“经济发展优先”的观念。作者指出，各级政府应该将人们的生活质量放在首位。
1.主旨大意题。文章主要分析污染原因，提出问题对策，第一段只是为了引起人们对污染的严重程度的关注，引起下文。故答案为C.
2.由第四段…which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders, ，“十二五”期间煤消耗增长30%到第五段第一句话“突显了一个关键问题，即‘经济发展优先’”可知，经济发展优先的观念阻碍了从根源上减少排放。故答案为B。
3.由第二段it is the burning of coal that is the biggest cause of air pollution一句可知，燃煤是造成污染越来越严重的根本原因。故选择A项。
4.污染越来越严重，燃煤是原因，但是根源却在于“经济发展优先”的观念。所以解决污染问题的关键在于改变观念。这就要求政府制定环保政策并有效实施。由最后一段But it also requires giving more priority to environmental issues in policymaking.可知B项正确。
5.作者对于环境污染越来越严重感到深深的忧虑。从最后一段故答案为D.
