摘要：In China, English, as an important tool for self-expression and mutual communication, is paid great attention to all over the country and College English has become a compulsory course at all colleges and universities. English writing is one of the most important language skills for college students. For a long time, English writing has been the throe throat for college students, which manifests in the aspects that students have poor vocabulary and employ much Chinglish expression in their essays, hindering them from expressing themselves clearly. Many linguists and teachers have been doing research on foreign language teaching, trying to find an effective way to improve the students’ foreign language acquisition especially foreign language writing. And thus the approach of employing the lexical chunks to teaching was put forward. The approach of teaching English writing by chunks offers a new way of solving the problems. Based on the previous research, the author thinks it necessary to probe into teaching English writing by lexical chunks so as to improve students’ writing ability. This study increases the input of English Lexical Chunk to College English writing and analyzes the effect of this method on students’ writing by conducting experimental research. According to the experiment analysis, it is concluded that increase of Lexical Chunk input can reduce the negative transfer of the native language, thus improving their writing in terms of wording collocation, sentence building, discourse cohesion and expression.
