George Lakoff experienced three stages in his theoretic development from an enthusiastic supporter of Standard Theory to the initiator of generative semantics and then a major contributor of cognitive semantics.

From the point view of sematic compound,syntax and metaphor,this paper tries to make meaning of the “strangeness” of the poetic language as well as its aesthetic function.

When studying WH-movement and constraints generative linguistics starts from internalized transformational device in human brain to explore into the transformational rules and cognitive linguistics explores into principles displayed in syntactic expressions on the theoretical basis of human cognition process.

In addition,the biological properties and the origin of language faculty are interpreted according to Noam Chomsky s thoughts on minimalism and the theoretical orientation of generative linguistics is also explicated.
