Interlanguage Pragmatics was founded in the 1980's,when the Second Language Acquisition was included into Pragmatics.The frame of reference of Interlanguage Pragmatics was set up essentially through the development of over thirty years,and many static and dynamic studies have been carried out.However,there are some insufficienies in the studies,and there are some areas to be further exploree in the future.Interlanguage Pragmatics drives from the Westen Countries,therefore,the study only focused on the acquisition of language of West languages in English domain.The study of Chinese as second language pragmatic acquisition is backword relatively,and should be reinforced further.
