Why is the distinction between competence and perf

正确答案：This idea was proposed by Chomsky in his formalist linguistic theories．It is sometimes hard to draw a strict line．Competence is affected by birth and obviously animals do not possess it．In other wordshumans share much the same in linguistic competence despite that they differ in skin coloracesex or society．Howeverlanguage performance is limited and varied in several ways--different linguisticfeatures(number of vowels or consonantslanguage typecollocationsetc．)social systemgenderetc．One case in point is that a girl usually has more flexible tongue than a boyor people in open society are communicative than those in less open society...Therefore it seems that what is left to be done about by education is not linguistic competence but linguistic performanceso to speakemphasis on communicative functions of language and creation of context to help language learners enhance their communicative skills． 这一区分是乔姆斯基在他的形式语言学理论中提出的。有时很难区分二者。语言能力受着先天的影响动物显然不具备语言。换言之人类的语言能力大体上相同不因肤色、种族、性别或社会相异而异；但是语言运用则受着多种因素的制约如语言特征(元音辅音的数目、类型、搭配等)、社会制度、性别等。举例说女孩子比男孩子口齿伶俐开放社会的人群比封闭社会的人群善言……如此看来留给教育的事情不是语言能力而是语言运用也就是重视语言的传递信息功能努力创造条件提高学生的语言交际能力。
