Many cities issued a warning of         air pollution for PM-2.5 readings, which became
        Concern of all the people

A.the; theB.the;/C./;aD.an;a

C

解析试题分析:第一个空,空气污染应是一个抽象的概念, 抽象名词前不用冠词;第二个空,表示泛指“关心的一件事”,故用不定冠词a。
考点:冠词的考查
点评:冠词的考查,其实就是在围绕该用不该用,用哪一类冠词。解答有关冠词的题型首先必须要把题目完完整整看清楚,理解句子意思,然后可以从三方面入手,一是习惯搭配,二是固定短语,三是具体语境分析。对于固定短语平时应多读多记。
