Abstract: The traditional approach to cohesion analysis is mostly based on the lexicon level, such as reference and substitution, which is a microcosmic method.And thus it can not reflect the holistic textual structure.Staging above words, this paper focuses on clauses' processes within SFG.The paper believes that processes of a certain text are well organized and ruled, and thus there is certain relationship among processes.By analyzing three essays of different genres, the paper shows that processes have the tendency of occuring repeatedly, prosodically, or sometimes in a combined model, which are referred to as processes concord and processes sequence.The processes concord and processes sequence analyses can help readers comprehend a text better and guide text writing.
