The Commentary for the third edition of this successful guide to writing has been revised and expanded in many ways to provide more support for instructors; this includes additional tasks for Units Two and Four to supplement the main text. However, the collegial tone established in previous Commentaries between Swales & Feak and instructors has been retained. This volume contains commentaries on each of the eight units plus the two appendixes. The format for each unit includes a summary of the main points of the unit along with a list of topics covered. a synopsis of activities, divided into Language Focus sections and description of tasks. some general notes designed to capture the character of the unit, to indicate alternative activities, or to anticipate problems that may arise. detailed commentary and discussion of individual tasks, including model or sample answers where possible.
