Abstract: The cognitive thinking methods-metaphor and metonymy-deeply influenced on the senses development. Through analysis of extended meanings of Chinese body nouns, it was found that metaphor and metonymy function as substitution，derivation and construction in the process of lexical meaning extension. By the action of metaphor and metonymy, three features-pattern，position and function of Chinese body nouns meanings have extended and transmuted in different ways. It finally establishes eight methods of semantic correlation. It will help us further reveal the range of action of metaphor and metonymy and conclude the modes of the senses development of Chinese body nouns. Investigation from deep layer shows that metaphor and metonymy even have important functions in semantic system, which help to establish the methods of semantic correlation and deeply influenced on the forms of lexical meaning extension and the semantic tendency.
