Chinese progressive aspect marker has always been the main topic of formal linguists. In spite of a large number of the researches on Chinese progressive aspect marker zai and zhe, controversies still remain. On basis of the binary opposition between dynamicity and state, many linguists around the world have analyzed and compared zai and zhe. Although this point of view owns its theoretical basis and language data, it has many flaws and could not explain some existed linguistic phenomenon. The controversies remain unsolved as yet.
The thesis adopts Chinese progressive aspect marker zai and zhe as research subject, and clarifies the differences between zai and zhe in meanings, linear order position and syntax as well as the co-occurrence of zai and zhe in one progressive sentence from the perspective of semantics, syntax and pragmatics on the basis of formal semantics and syntax.
