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.
