“功能”是一个普遍使用的词汇,指事物或方法所发挥的有利的作用、效能。记得“文革”中,曾拍了一部影片,里面有位教授因给学生讲授“马尾巴的功能”,被批判为“唯功能论”,而受尽嘲讽。在嘲讽批判者看来,小小的马尾巴,能有什么功能?纵有一点功能,与马头、马腿、马身比起来,这点功能又算什么?值得这样专门讲授 “Function” is a commonly used term for the beneficial effects and effectiveness of a thing or a method. I remember during the “Cultural Revolution”, I had taken a film in which a professor was taught to give the students the “function of a pony tail” and was criticized as “the theory of the function of monopoly” and was ridiculed. In the eyes of the taunts critic, what is the function of the little pony tail? What is the function of this kind of function when compared with the horse’s head, the horse’s leg and the horse?
