Abstract:

In speech communication, the choices of the reference forms of expressive subject constrain and influence the forms of entire discourse and structure The general syntactic study does not attach importance to this issue seriously Under the framework of role and reference grammar, the syntactic realization is analyzed from the role of speaker, the role of listener and the role of the third party respectively From various perspectives, differences in the meanings and functions of references are interpreted, if the expressive subject takes different reference forms in the same syntactic position of the same language The meaning and functional differences of the same reference in different syntactic positions are also explained Through innovative research methods, some rules and characteristics of the generating forms of discourse are explained, in order to better achieve different communicative intentions

Key words:  role and reference grammar, expressive subject, discourse form, self-reference
