Abstract
In the context of English for Specific Purposes (ESP), the emphasis is on the communicative aspects of language and its linguistic properties. In the teaching process, the principles of grammar are not enough. Teachers should be involved in the analysis of discourse and its implications to language teaching materials. The aim is to teach learners how to handle discourse in English. In this paper, we will try to demonstrate the ability of the students in an ESP context to shift from the level of a sentence to the level of an utterance. The transfer of a set of sentences into discourse is a good example for the development of the knowledge of the grammatical structures to the communicative use of the language.
