It provides ample opportunities for practice through extensive and varied exercises leading to communicative activities. Although it focuses on grammar, it promotes the development of all language skills. It includes numerous new exercises with, at the end of each chapter, cumulative review exercises that include additional communicative and interactive student-centered tasks.
