This study attempts to explore the construction of the essential academic skills of the English for General Academic Purposes (EGAP) from the analysis of the current situation of EAP teaching to the undergraduate students and the publication of the EGAP textbooks in mainland China. Based on the above two issues, this paper constructs the nine essential EGAP skills and recommends that teachers design the relevant teaching materials according to the skill system, in order to establish the scientific development concept of EGAP teachers, and thus to promote the effective EGAP teaching in the Chinese college EFL context.
