摘要
语境和语体是语言学研究中频繁出现的话题。依据维索尔伦关于语境的分类来探索交际语境与语体间的关系，得出交际语境和语体之间的关系是不变的，即前者制约着后者而后者映射出前者。
The paper studies concepts and types of both context and style from sociolinguistic point of view and comes to the conclusion that there is an unchanging rule about the relationship between communicative context and styles classified on the basis of formality degree, that is, the former determines the latter and the latter reflects the former.
