选择题
(2013·山东师大附中一模)To the great disappointment of the poor workers, a great part of their wages were ________ by the boss for no good reason.
A．kept away
B．kept off
C．kept up
D．kept back
答案
答案：D
句意：让贫困工人大为失望的是，他们的大部分工资被老板无理扣留。keep back“保留(扣留)某物”，符合句意。keep away“避免接近，远离”，keep off“使不碰到，使避开”，keep up“继续下去，坚持下去”，均不符合句意。
