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。
