This text is aimed at students of computing and IT at universitie well as in-work professionals specializing in computing and IT, who wish to upgrade their knowledge of English. Key features include 25 topic-based units each covering a key area of IT and a variety of topical texts and visual material, taken from textbooks, newspapers, computing magazines, web pages, manuals, and advertisements. The course revises and practises grammar and functions appropriate to the needs of IT specialists at intermediate level. It develops all four skills, with the main emphasis on reading. Most units end with longer specialist reading texts. These are intentionally challenging, and can be used either for homework or self-study. The tasks - such as writing, exchanging information, and problem solving - encourage learners to combine their subject knowledge with their growing knowledge of English. It provides full support for teachers who are not IT specialists.
