问题 The ship’s generator broke down, and the pumps had to be operated______instead of mechanically.
选项 A、manually
B、artificially
C、automatically
D、synthetically
答案A
解析 A选项manually意为“手工地”。根据句意： “船舶的发电机出了故障，所以得用手工操作泵来代替机械操作”，故选A。 其他三项中，B选项artificially：人为地；C选项automatically： 自动地；D选项synthetically：综合地，都不符合句意。
