試題分析：考查冠詞。冠詞the表特指，指上文提到過的人/事物；雙方都知道的人/事物；“兩者中較…的”那一個(gè)人/事物。冠詞a/an表泛指，即所說的人/事物對(duì)于聽者/讀者來說可能是不知道的，泛指某一類人/事物；某類人/事物中的一個(gè)/任何一個(gè)。在表示泛指一類人或事物的復(fù)數(shù)名詞前，一般不用冠詞，如：She likes reading stories。在本題中word在句中表特指，特指“PM 2.5”，所以用the; media reports是復(fù)數(shù)，且表泛指，不用任何冠詞，故選A。句意：由于“ PM 2.5 ”多次出現(xiàn)在媒體的報(bào)道中，公眾很想知道它的真正含義。考點(diǎn)：考查冠詞
