A Corpus-based Study On Collocation Of The Key Words In Business English

It is well-known that collocations are gradually beginning to occupy a relatively important place in the field of linguistics and applied linguistics. Nowadays collocations become the flouring area of corpus linguistics. A lot of researchers are interested in this field. Corpora now relies on the modern computer technology, which can make the running texts of tens and thousands millions words possible. Recently, corpus-based research has focused on the importance of recurring patterns of lexis by looking at natural language in large enough quantities. It makes the study of lexical behavior seemingly out of the question in the past, but actually out of question at present.The thesis is divided into five parts. A general description of the research background of this thesis will be given. It also tells us the objective and significance of the thesis. Finally, the organization of the thesis will be outlined. The literature review concludes the corpus and corpus linguistics, the background of collocation and its definition, keywords and so on. The data source used in the study, which refers to BEC is introduced in a comparatively detailed way, together with procedures for the collection of data which is the basis of our study. The results of the data processing are listed and analyzed in a scientific and systematic way. The wordlist will be computed. And according to the calculation as well as the comparison, the keywords will be identified. For the top four keywords in the BEC will be applied in the discussion of their collocation. Finally, the collocation studies on the keywords in Business English corpus will be made a summary. Implications and the suggestions for further study are also illuminated.
