19.Wuhan,the capital city of Hubei province,has issued smog warnings for three days since Monday because of serious air pollution.
The lingering smog forced construction sites to stop work and primary and middle schools to suspend outdoor activities.From Monday through Wednesday,the city's air quality index reading remained high,with the highest reading at 323,with PM2.5,or particulate matter smaller than 2.5 microns,as the main pollutant,according to the city's meteorological bureau.Any reading over 300 is considered"seriously polluted".
The city experienced at least eight heavily polluted days in the first two weeks of December,with the air quality index reading reaching a high of 440,China News Service reported.
Among those affected was a square dancing team in Jiang'an district,which had to stop daily practices after several members fell ill.Square dancing is a common open-air fitness practice across China,with most of the participants middle-aged or elderly women.

分析 本文講述了政府出臺警告措施的原因--霧霾嚴重,以及解決方案.
解答 67.B主旨題.本文主旨句是第一段,"Wuhan,the capital city of Hubei province,has issued smog warnings for three days since Monday because of serious air pollution."后面的內容主要解釋政府出臺警告措施的原因--霧霾嚴重,以及解決方案.只有B項符合題意,故正確答案為B.
68.C細節(jié)題.文章第二段第二句提到323,是從周一到周三空氣質量指數(shù)的最高值,文章第三段提到440,是在12月份開始兩周的最高值,440是文章中提到的關于空氣質量指數(shù)的最高值,故正確答案為C.
69.A推斷題.由最后一段第一句可知"武漢將在2017年前控制好空氣質量",由最后一段第二句可知"將在2016年前加快發(fā)展清潔能源型汽車,將重污染的車遷移",2016在2017之前,第一步應是后者,即"綠色交通",故正確答案為A.
70.A推斷題.由劃線處后"after she learned her illness was caused by smog"可知,此處應指"暫停實踐",put off"推遲,延遲",take off"起飛;脫下",put up"提供;建造;舉起",take up"拿起;占據;開始",只有A項最合適,故正確答案為A.
