EFFiCiEnt和EFFiCtivE

efficient与effective的区别 a.efficient是指工作效率高;其名词形式为efficiency,意为“效率,功效”.b.effective是指某种事物起了作用,产生了效果;其名词形式为effectiveness,意为"效果,有效".[例句]anefficientsecretary工作效率高的秘

两者意思根本不同,不属于近义词辨析.effective指“有效的”,是“有”与“没有”的范畴;efficient指“效率好的”,是“好”与“不好”的范畴.首先要effective,才能谈是否efficient.

efficient和effective都是形容词,但前者强调效率高,后者强调效果好.效率和效果,这两个概念虽然是一字之差,但含义截然不同.工作效率,一般指单位时间内完成的工作量,通俗地讲就是在进行某任务时,取得的工作量与所用时间、精力、金钱等的比值.产出大于投入,就是正效率;产出小于投入,就是负效率.工作效率是评定工作能力的重要指标.提高工作效率就是要求正效率值不断增大.一个人的工作能力如何,很大程度上看工作效率的高低.如果工作效率高,就用形容词efficient.效果,一般是指由某种因素造成的结果,如果某种因素造成了正面的结果,就要用形容词effective.

effectual指物而不指人(of things no people,出自牛津高阶英汉双解词典),与effective相比多用于书面语!
