Learners increase their active vocabulary from 300 to 800 words. Five thematic reading selections per unit recycle vocabulary, sentence structure, and content knowledge. Carefully designed pre-reading work and post-reading comprehension activities build students' reading and critical thinking skills. A variety of exercises and games as well as dictionary activities and collocations recycle key vocabulary found throughout the readings. Pages 142-178-256 are blank pages, that's why they weren't scanned. Page 250 will be scanned later on. For the time being it's missing.
