Whether the knowledge of college students can be made public to the society, in fact, the confidentiality requirements for different aspects of knowledge are different. Knowledge of some subjects, such as college English test methods, common test sites, CET-4 and CET-6 test skills, CET-4 and CET-6 test outlines, and text contents of some textbooks, can be made public to the public. However, some unpublished papers, periodicals, declared projects and some academic research will have corresponding confidentiality requirements, and not all of them can be made public. On the one hand, it is to ensure the patent and ownership of knowledge, and now plagiarism is too serious. On the other hand, some knowledge has put more efforts into it.
