The researchers found that the specific problems existing in their writings are identified as poor content, incomplete generic structure and misuse of cohesive devices. Therefore, on the basis of the previous studies, this study attempts to use Martin's genre theory to resolve the existed problems of the Professional College English major's students in writing and enhance students' discourse writing ability. Meanwhile, this study tries to answer the following questions:(1) Compared with the traditional writing teaching methods, whether the genre-based writing method has a significant effect to improve students' writing skills;(2) Whether the genre-based writing method is possible to increase students' interest in writing. The experimental result and the questionnaire show that genre-based approach in ESL writing teaching really can improve students' writing achievement and enhance students' interest in English writing.展开更多
