English supplementary book for the intensive course on CD

Foreign languages are increasingly important in an age of global travel and growing economic relations. They are important for everyone, both personally and professionally. The Intensive English Course on CD is intended for all those who want to take their first steps in learning the English language, as well as for those who wish to refresh long-forgotten knowledge.
A comprehensive accompanying book provides not only the texts, the Portuguese translation of the dialogues and exercises, but also the information and clarifications necessary for the correct use of the language.
