Language acquisition is far more than targeting its surface systems including grammatical patts, lexical meanings, set structures and the like. It is for it that a shift is naturally coming up, i.e. more and more peoples increasing conc on language use in real situations. For adult leers in China, English is quite different from the mother tongue that can be acquired naturally and with ease. In the leing process, linguistic knowledge is usually taught first, and then for the purpose of grasping language skills leersautomaticization should be involved. On the ground of the fact that classroom teaching is the main channel for most college studentsto have their language input, teacherswise strategies and full use of classrooms are quite essential for their lan-guage intake and general level as a whole. To enhance studentspragmatic competence, i.e. the ability to apply language flexibly and appropriately, this paper tries to find a way out in view of this concept, namely, the promotion of pragmatic competence by dis-course analysis in writing classes.
