ENGLISH FOR SPECIFIC PURPOSES

English for specific purposes (ESP) is a subset of English as a second or foreign language. It usually refers to teaching the English language to university students or people already in employment, with reference to the particular vocabulary and skills they need. As with any language taught for specific purposes, a given course of ESP will focus on one occupation or profession, such as Technical English, Scientific English, English for medical professionals, English for waiters, English for tourism, etc.[1] Despite the seemingly limited focus, a course of ESP can have a wide-ranging impact, as is the case with Environmental English.[2]English for academic purposes, taught to students before or during their degrees, is one sort of ESP, as is Business English. Aviation English is taught to pilots, air traffic controllers and civil aviation cadets to enable clear radio communications.

专门用途英语(ESP)是英语作为第二语言或外语的一个子集。它通常指的是向大学生或已经就业的人教授英语，涉及他们需要的特定词汇和技能。与任何语言教为特定目的,给定的ESP课程将集中在一个职业或行业,如技术英语,科技英语,医学英语专业人士,服务员英语,旅游英语,等。[1]尽管看似有限的关注,ESP课程可以产生广泛影响,与环境一样英语。[2]在学生获得学位之前或学位期间教授的学术英语，与商务英语一样，是一种专门用途英语。向飞行员、空中交通管制员和民航学员教授航空英语，使无线电通讯畅通无阻。
