Designed to support secondary school student writers by allowing them to avoid or correct the most common types of usage errors, this manual/workbook is more than simply a descriptive grammar. Rather, it achieves its intended purpose by providing an abundance of exercises by means of which students can build mastery and confidence. Short, clear explanations of the principles examined as well as the problem sentences are engaging enough to overcome the resistance that grammar naturally excites in all right-thinking people. Appealing humor related to the experience of adolescents and to their sense of the absurd is generously included throughout. A battery of SAT-style exercises to assist in preparing for the new writing section of the exam covers paragraph revision, error identification and sentence revision.
