Sinopse
American Dimensions Advanced is a revised, American version of the British English Fourth Dimension. As with American Dimensions Intermediate, this version has ten units. Each unit consists of at least two reading sections, two language study sections, and a writing section. Listening and discussion exercises accompany most of the reading and writing sections to improve students' communication skills. Language summaries follow every two units, so students can review as they progress through the book. It aims to balance fluency and accuracy work across the four skills and emphasizes vocabulary and pronunciation development.
