问题 The rocket was______ into space from the launching pad. After three minutes, it vanished in the sky.

选项 A、forced
B、pierced
C、propelled
D、propagated

答案C

解析 题意是:火箭从发射台被______入太空。三分钟后,它消失在天空中。 [C] propelled“推进”,指借助于外力或燃料等产生的动力推进某物前进,符合题意。 [A]forced“强迫”;  [B] pierced“穿破,刺透”’一般指刺透有形的东西;  [D] propagated“散布,传播”,如可指信仰者或成员的增多、活动的频繁或信息的传播等。因此,这三项都不符合题意。
