Therefore,language can never be independent from human cognition,and is obviously humanistic in nature,so language can never be free from anthropocentricism – one of the major criticisms from ecolinguistics(EL).

In the 21st century,when ecolinguistics became an independent language subject,people had focused on language biology more and more strongly.

Moreover, it is another attempt on the application of ecolinguistics developed by Einar Haugen in 1970 into the maintenance of diverse languages and the preservation of minor.

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.

Adopting the biolinguistic approach,generative grammar develops as a part of biolinguistics.
