After the publication of Cohesion in English by Haliday and Hasan, the theory of cohesion was established. It attracted much attention from academic fields since it was established because it played an important role that could not be ignored in many linguistic fields such as textual analysis, theory of translation, man-machine conversation and the study of stylistics. In this thesis, English cohesive devices, the theory of Halliday and Hasan, and their own characteristics are analyzed. After that, considerable materials about English Writing Teaching of cohesive devices are analyzed. Chinese English teachers in Chinese High School pay insufficient attention to it as a result students lack the ability to use cohesive devices wisely in their writing, which makes their writings lack coherence and logic. At present, Methodology of cohesive devices in Chinese teaching has blank area. As a result, the methods of teaching them(Reference, Ellipsis, Conjunction and Lexical Cohesion)are presented one by one in the thesis in order to improve students abilities to use cohesive devices wisely, which helps them to make their writings cohesive and logical so that the comprehensive writing situation in Chinese High School can be improved.
