English for International Trade is a compulsory course for the junior English majors of business English orientation in our university.Before 2008 English for international trade was only a language-based course in which articles about international trade were read and relevant language points were explained, but the consistent theories and practices of international trade were not included so that the students could not integrate their language skills into the practical environment of international trade.We have been looking for a way to combine the English teaching to the separate teaching of international trade.After a few years teaching we find that teaching in English with the use of an English version textbook of international trade is efficient in the "Double Modules" under the direction of "Double Principles"."Double Modules" refer to the classrooms and the internship sites; "Double Principles" refer to the principle of teaching international trade in English and the principle of various teaching methods for different teaching materials.In this way the students English skills and their potential logical and creative thinking is developed and our teaching achieves efficiency.
