ESP (English for Specific Purposes) has been the focus of much attention recently but the question arises of “what can ESP do?” Proposed here are three things that are possible with ESP. The first is using ESP as a tool to help students who are not English majors learn how language “works” via the concept of genre texts. The second is using an ESP approach to simulate professional communication contexts in order to raise student interest and motivation. The third is to aim for ESP bilingualism, which is a realistic and attainable goal. All three points will be illustrated with specific examples.
