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 plentiful clear examples, grammar charts and tables. The two-color new edition will be easier to use, with exercises such as error identification, error correction and sentence construction tasks consistently following each grammar point.

Each unit ends with a writing assignment and a flowchart to help students diagnose their writing problems and edit their writing.
