语法与词汇 11.The hum of conversation______as the chairman mounted the rostrum.

A、 died out
B、 died off
C、 died of
D、 died away

【正确答案】 D

【答案解析】D项“die away(声音等)逐渐消失”符合题意。如：The noise of the motor car died away．(摩托车的噪声消失了。)其他三项“A项die out灭绝，消失；B项die off相继死去直至死光；C项die of死于”都不正确。本题是说当主席登上讲坛，说话的嗡嗡声逐渐消失。因此D项为正确答案。
