Apart from failure to be accustomed to the local cultural environment and the ideological rejection at the surface level,there have also been such reasons as the limit of the utterers deep-structure thinking mode and their loss of epistemological principles so that the debates .

Through analysis and interpretation on the nature,cognitive principle,operational models and cognitive motivations of conceptual metonymy,the paper attempts to demonstrate that,as a conceptual mapping in a domain,metonymy is a cognitive process in which one conceptual entity,the vehicle,provides mental access to another conceptual entity,the target,within the same idealized cognitive model.

The distributional pattern of grammatical aspect across lexical aspect and the developmental sequence is believed to be influenced by the similar pattern in the input and semantic prototype,both of which interact with some universal cognitive principles.

The thesis is a cognitive study of the Chinese non-stereotypical VO constructions with the cognitive theories (stcrcotype category theory, metonymy, metaphor, cognitive frames, cognitive principles, construction grammar) in the hope to find the motivations behind the generation and understanding of the constructions.

The impacts of cognitive principles and communicative principles on metonymy should not be ignored when metonymy is defined from the angle of conceptual contiguity.
