《朗文英语正误词典》有这样一段话:
× The medicine proved very efficient.
√ The medicine proved very effective. 这种药证明很有效。
我觉得 The medicine proved very efficient. 这句英语是可以接受的。
efficient 与 effective 意义很接近。efficient 强调“能够工作得很好”。它的名词是 efficiency(效率)。an efficient engine(plan, man, manager, secretary)是指高效率的机器(计划、人手、经理、秘书)。effective 则强调“成绩好”。它的名词是 efficacy。an effective way(有效的方法),an effective speech(效果很好的发言),effective measures(有效的措施),effective scientists(成绩卓著的科学家)。有一本英语著作说,an efficient police-force 是强调它的纪律、组织和行动能力,而 an effective police-force 则是强调它做事的成绩。由此可见,说 The medicine proved effective. 在于强调“药有效,治病效果好”。The medicine proved efficient. 则在于强调“药的高疗效”,比如说,其他药服 20 剂能治好某种病,而此种药服 3 剂便可治好该种病。因此,上面的两个英语句子都是正确的,只是着重点有所不同而已。有时它们之间的差别非常细微,以至于可以互换。
