Language is a vital means for communication. It is used to exchange ideas, thoughts and opinions. It shapes the way people think, talk and write. Through language, people can convey their feelings, emotions and attitudes. Also,  Language is used to spread knowledge and culture that produce fruitful communication.
       Mathews (2008) confirmed that English can often serve as the global language between two people from a pair of different cultures, neither of whom speak English as his/her native tongue. It is therefore very important for university students to learn English and be able to communicate orally in it; this skill could help them greatly in securing and keep in job, especially with multinational companies……. Consequently ,if students would like to be a part of globalization, they must be able to communicate successfully in English.
One of the most important disciplines of the English language in human activity was English for specific purposes (ESP). ESP was a phenomenon grown out of a number of converging trends of which Bojovic (2014: 487) mentioned three most important: 1) the expansion of demand for English to suit specific  needs of a profession, 2) developments in the field of linguistics (attention shifted from defining formal language features of discovering the ways in which language is used in real communication, causing the need for the development of English courses for specific group of learners), and 3) educational psychology (learner's needs and interests have an influence on their motivation and effectiveness of their learning).
ESP course is one of the components in a leaning target situation. Gatehouse (2001) states that the teaching of English for Specific Purposes has always been with needs analysis and preparing learners to communicate effectively in the tasks prescribed by their field of research
