索绪尔认为言语是人们所说的话的总和。语言是言浯活动事实的混杂的总体中一个十分确定的对象,是言语活动的社会部分。语言是一种表达观念的符号系统。语言符号具有任意性,是概念和音响形象的结合。这些理论有助于我们了解语言学习的本质,对改善学习方法和提高外语能力有着深远的影响。 Saussure believes that speech is the sum of what people say. Language is a well-defined object in the interplay of the facts of speech, the social part of speech activity. Language is a symbolic system of ideas. Language symbols are arbitrary, is the combination of concept and sound image. These theories help us understand the nature of language learning and have a profound impact on improving learning methods and improving foreign language skills.
