This new course has been specially written for adults who need English for work, travel and everyday social situations. With Powerbase, they can: — start speaking and writing immediately with structured communication activities in every lesson; — gain a thorough understanding of the essential grammar required for practical tasks and socialising; — learn the key words, phrases and skills that they need in their working lives; — practise listening and pronunciation skills; — develop the reading skills to deal with e-mail and the web as well as standard texts. Powerbase is designed to be flexible. The 40 double-page lessons plus five review units can be extended with additional activities and photocopiable pages from the Teacher's Book.
