The focus of genre analysis is generally on the analysis of generic constructs with little attention to contexts. Nowadays many scholars even including Bhatia in Swalesian school think a multi-perspective genre analytical framework is needed. The author of the paper thinks that since any discourse or genre is the product of social practice with a communicative purpose and its analysis should be context-dependent. In view of this, the author claims that a multi-perspective genre analytical framework can be built by integrating social context and thematic development into the existing genre analytical framework. The new framework can be used to have a thorough explanation of what well-formed and communicatively effective discourses are like. The feasibility of the new framework is further demonstrated by the analysis of IELTS writing. Findings show that native speakers’ discourses contain three obligatory Moves and seven Steps to build global coherence. Texts of Band 8 develop successfully through all the obligatory Moves and most obligatory Steps. Texts of Band 4.5 and Band 6 do not provide a very strong argument because some of obligatory Moves and Steps are missing. Native speakers of English tend to use simple linear progression patterns, derived rheme and continuous rheme progression patterns to build local coherence. EFL learners across all levels do not pay enough attention to rheme-rheme interaction. Native English speakers use more material and relational process. Furthermore, they express their viewpoints and reasoning in a more implicit way. EFL learners, on the contrary, use more relational process. In addition, they express their viewpoints and reasoning in a more explicit way. The results of the study can be used in writing teaching to help EFL learners write communicatively successful discourses.
