1 Introduction
    Writing can directly reflect one’s command of one language. So writing ability is quite essential to every English learners. But for long, Chinese students always have the problem in writing a good essay even most of them have learned English for more than a decade. The beginners of English studying usually focus on vocabulary, grammar and sentence pattern whereas ignore the importance of structure of the text. The mistakes occur in compositions of high-level English learners are not often on grammatical level, but on structure and coherence level. Especially when the problems come to coherence, learners have no ideas how to deal with them. Taking English as the second language, most learners still think in a native-language way instead of thinking like a native English speaker, which lead to the incoherence in their English writing. Their ignorance on the significance of lexical repetition/cohesion is a main problem. Since lexical repetition/cohesion is an important standard to judge coherence, analyzing and improving students writing skill on lexical repetition/cohesion should not be ignored. 不同年级学生英语议论文写作词汇重复研究:http://www.751com.cn/yingyu/lunwen_23665.html
