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。
