10．Cities need to put efforts to deal with pollution and clear the air．
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015，according to the latest plan released by the State Council．
Besides the existing pollution control program for CO2，regional emission caps（区域排放上限） for other certain chemicals will be established in the three key air polluting areas-the Yangtze River Delta，Pearl River Delta and the Beijing-Tianjin-Hebei region．Coal-consumption caps will also be tried out in some areas，according to the plan．
The plan is aimed at dealing with regional air pollution-such as acid rain and smog-which have become increasingly obvious in China in recent years and caused a severe threat to people's health，Zhang Lijun，vice minister of environmental protection，said in an interview on Monday．
The air quality in a city affects the areas nearby because pollutants can travel in the sky，said Chai Fahe，vice director of Chinese Research Academy of Environmental Sciences．
"So efforts to reduce air pollution in a single city，targeting a certain pollutant（污染物） will not be enough，"Chai said．
Zhang said the country's major industrial districts-the Yangtze River Delta，Pearl River Delta and the Beijing-Tianjin-Hebei region-have recorded more than 100misty days annually in recent years．
These three regions，home to at least 200million people，occupy only 6.3percent of the country's area but consume 40percent of the country's coal and produce half of its steel，according to official figures．
Studies also show that the visibility（能见度） in eastern regions of China has dropped by 7to 15km compared to that in the early 1960s，as a result of air pollution．
Liaoning province，the Shandong Peninsula，Wuhan in Hubei province and its surrounding area，the Changsha-Zhuzhou-Xiangtan region in Hunan province，the Chengdu-Chongqing region，and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs，according to the plan．
The new plan also requires an improved air quality system，which will measure the pollution levels．"The current system，which only measures some major pollutants，cannot reflect thetruepicture．"said Chai．
57．It will not be enough to reduce air pollution in a single city becauseC．
A．air pollution has been becoming more and more serious in recent years
B．air pollution like acid rain and smog is threatening people's health
C．air pollutants in a city can travel in the sky and affect nearby areas
D．air pollutants stay in fixed places over the cities
58．Suppose the visibility in eastern regions of China was 130km in the early 1960s，the visibility there nowadays isA．
A.123to 115km B.137to 145km
C.123to 145km D.115to 137km
59．The main purpose of the passage isB．
A．to inform readers of the damage caused by air pollution
B．to introduce the new plan to control air pollution
C．to provide official figures of air pollution levels
D．to point out the regions affected by air pollution
60．What does the underlined phrase"the true picture"in the last paragraph mean？D

分析 空气质量由于污染而急剧下降，中国政府计划将采取新措施来治理污染，尤其是在一些重污染区，如长三角、珠三角、京津冀等地．
解答 57．C 细节理解题．根据第五段The air quality in a city affects the regions nearby because pollutants （污染物）can travel through the atmosphere可知答案为C项．
58．A 推理判断题．根据倒数第三段可知，如今的能见度比20世纪60年代下降了7到15千米，如果60年代为130千米，则现在为123到115千米．故答案为A项．
59．B 主旨大意题．本文为新闻报道的形式，主要介绍了中国为控制大气污染而采取的新举措，故答案为B项．
60．D 词义猜测题．最后一段提到，在这项新计划中，新的监控体系将会监控污染水平，而目前的监控体系只能监控主要污染物，无法监控到（污染水平）．由此得知答案为D项．
