With the efforts of the Beijing government and citizens over these years, the air condition of the city has gradually improved.The number of blue skies climbed to 229 in 2004 while the heavily polluted days were greatly reduced to 17. The progress continued each year with an increase of 5 － 7 good days and decrease of 8 － 12 bad air days until the end of 2007, though there was an exception in 2006 with 24 days heavily polluted.The changing numbers are due to the fact that people become more and more aware of the enviroment around them. In addition, the government has continued with its measures. Air quality monitoring traffic control and tree planting are just some of the ways to improve the conditions.We believe that the city will see more blue skies and fewer air － polluted days in 2008 and thus ensure a “Green Olympics”. More people will be able to enjoy the blue skies in Beijing.Ⅰ. 重点单词1 ． ______(vt.) 供给；供应 (n.) 供给 ( 量 ) ； ( 常用复数 ) 供应 品；生活用品2 ． ______(adj.) 普遍的；分布广的3 ． ______(n.) 首领；上...
