The introductions are the essence of academic papers, so it is particularly important for postgraduates to write English introduction.

And this study is to explore English postgraduates how to choose genre structure, language forms and the communicative purpose that the introductions should achieve. The result shows that some English introductions of the masters' graduation thesis differ from the international general pattern in frequency and quantity of moves, due to the influence of the context. To some extent, this study is significant in teaching academic paper writing.
