Coherence 1. Introduction Coherence of discourse analysis is a core problem. Because of the complexity of the coherence itself, there is no systematic standards and methods of the explanation on the coherence. Halliday and Hasan (1976,198 5) first put forward the four categories on grammatical cohesion and the means of lexical cohesion, they think that coherence is formed on the basis of cohesion, and cohesion is an essential condition for coherence (1985:94). This theory has caused many queries and criticisms of scholars. Enkvist (1978:110) points out that cohesion is neither an necessary nor the sufficient condition to realize the coherence of a text. Brown and Yule (1983:66224) hold the view that people explain a discourse according to a hypothesis that discourse is coherent not the form markers of discourse. Widdowson (1978:28-31) points out thinks that cohesion can be considered as symbolic language relations between proposition and proposition; while coherence is the relation between the illocutionary acts. Stubbs (1983:96) also thinks that a reader or listener can give or create the discourse coherence on his own cognitive ability That is more worthy of our attention. Givon (1995) has argued that the discourse coherence is not in the external discourse but in the psychological coherence in the mental text. He regards coherence as a psychological phenomenon, a kind of subjective behavior which was continually negotiated by recipient or both parties in communication process to be understood. In addition, de Beaugrande and Dressier (1981), Hobbs (1979), Cook (1994), McCarthy (1991), Fries (1983), Reinhart (1980) and Hoey (1991,2001) also separately analyze the essence, mechanism and performance characteristics of coherence from different aspects. Many domestic scholars have also explained and supplemented the theory (such as Cheng Yumin, Huang Guowen 1988; Hu Zhuanglin1994; Zhu Yongsheng1996;1997; Zhang Delu, 1999;2000 etc.). Ge
