摘要:The aim of this paper is to analyse the role of textbooks in English for Specific Purposes (ESP) teaching, a field where in-house materials seem to be the most appropriate option. The usefulness of textbooks often depends on their successful adaptation and our contention is that teachers do not have to be specialists in tailoring materials. In addition, textbooks are an important tool for students and this assertion is supported by the results of a questionnaire carried out in the field of Business English. The conclusion reached in this paper is that, although the perfect textbook may not exist, it is possible to settle on a compromise which suits our students. needs and at the same time reflects the teacher.s view of the teaching-learning process.
