CHAPTER TWO LITERATURE REVIEW
2.1 Previous Studies on Genre Analysis
In light of the development of genre and genre analysis, different scholars offer various definitions of genre. Generally speaking, it is the use of language in conventionalized communicative settings or “discourse community”, to address it more directly (Bhatia, 1993). A genre comprises a class of communicative events, the members of which share some set of communicative purposes. These purposes are recognized by the expert members of the parent discourse community and thereby constitute the rationale for the genre. This rationale shapes the schematic structure of the discourse and constrains choice of content and style (Swales, 1990). In the 1990s, the concept of genre has developed into a serious issue in applied linguistics and there has been a growing interest in using genre as a powerful tool for studying language use in context and cross-disciplinary areas (Paltridge, 1997). And usually the study of genre primarily focuses on three aspects: the textualization of lexico-grammar, the organization of discourse and the contextualization of discourse (Bhatia 1993 & Bhatia, 2004; Swales, 1990). Bhatia (1993) even proposed seven analyzing steps for studying a new genre: placing the given genre-text in a situational context, surveying exiting literature, refining the situational/contextual analysis, selecting corpus, studying the institutional context, linguistic analysis, specific information in genre analysis. In this thesis, the author will follow these analyzing steps and may neglect some of it to adapt to the research.

2.2 Previous Studies on Transitivity Analysis
Transitivity analysis belongs to the Systematic Functional Grammar of Halliday, which expresses the ideational meaning of texts. In Systematic Functional Grammar, there are said to be three metafunctions of language (Halliday, 1970): textual function, which provides links between language and the features of the situation in which it is used; ideational function, which serves for the expression of “content” or the speaker’s experience of the real world, including the inner world of his own consciousness (in thi
