Abstract:With the increasingly frequent international academic exchanges, it is more and more important to improve the international academic exchanges of postgraduates. The three courses of "professional foreign language", "scientific paper writing" and "graduate academic English" can improve the international communication ability of graduate students to different degrees, but these three courses do not form a joint force and fail to achieve the best effect of education. This paper makes a comparative study of the three courses from the aspects of teaching content design, teachers' background, postgraduate tutors and postgraduate after-class feedback, and explores a way to improve the international academic communication ability of postgraduate students.
