This text provides a guide to the most common errors students make in writing. The emphasis is on errors made in writing formal academic discourse. The book has 20 units. Each one examines an area of grammar—such as verb tense choice, article usage, and modals—and then pinpoints the most troublesome grammar points within that area. Each unit provides a straightforward description of the grammar point, supported by clear examples, grammar charts, and tables. Practice activities, such as error identification, error correction, and sentence construction follow the description of the grammar point, so that students can consolidate their understanding. Each unit ends with a writing assignment and a flowchart to help students diagnose their writing problems and edit their writing.
