What is characteristic of learners of special English?

There are three groups of English learners: beginners, intermediate learners and learners of special English. Beginners need to learn the basis of English. Students who have reached intermediate level benefit from learning general English skills. But what about students who want to learn specialist English for their work or professional life? (11[D]) Most students. who fit into this third group have a clear idea of what they want to learn. A bank clerk, for example, wants to use the specialist vocabulary and technical terms of finance. But for teachers, deciding how to teach specialist English is not always so easy. For a start, the variety is enormous. Every field from airline pilots to secretaries has its own vocabulary and technical terms. Teachers also need to have an up-to-date knowledge of that specialist language. And not many teachers are exposed to working environment outside the classroom. These issues have influenced the way specialist English is taught in school.
     This type of course is usually known as English for specific purposes or ESP. (12[A]) And there is an ESP course for almost every area of professional and working life. In Britain, for example, there are courses which teach English for doctors, lawyers, reporters, travel agents and people working in the hotel industry. (13[B]) By far the most popular ESP courses are for business English.
