A Corpus-Based Study on Oral Language Education of Police English

There are many problems in the practical education of police English, for example, students' English application ability and police English teachers' professional knowledge reserve are difficult to meet the practical needs, the teaching content of police English is not systematic, and there is a gap between the needs of students' police English and teaching, etc. For the research of oral language teaching of police English, micro corpus can meet the requirements. It is most appropriate to limit the number of words in the corpus between 300 and 500 words. The excess or insufficient length of the corpus should be appropriately deleted and supplemented to facilitate retrieval and extraction in the process of use. Usually, the unified form is TXT format. After the application of information technology teaching methods, the oral English course shows the greatest significance. It can reflect the characteristics of the course in practical innovation, and the innovative course is more suitable for practical education
