Traveller Beginners - Teacher's Book

Traveller is an exciting and easy-to-use seven-level course in English, which smoothly takes learners from Beginners to Advanced level. The main concern of the writer of this course has been to explicitly demonstrate how English is used in real-life situations, thus enabling learners to use it in meaningful contexts. Traveller has been meticulously designed to build the learners' ability to communicate their ideas fluently, accurately and confidently.
