Grammar Advantage is a course text and self-study tool for advanced learners of English as a second language (C-TOEFL score of at least 190 or equivalent). Clear examples and explanations are followed by varied and abundant exercises. Topics that are important in academic contexts are highlighted: sentence structure, transitions, and sentence flow, verb tenses, active and passive voice, gerunds and infinitives, reporting and noun clauses, relative clauses, adverbials, and conditionals. Coverage of basic rules and finer points of usage help students understand not just basic grammar but how individual words are used (lexical grammar). Easily referenced subsections and sections on errors to avoid enable teachers to guide students to edit their work. The text includes four appendices (Tense Overview, Basic Punctuation for Joining Clauses, Transition Expressions Word by Word, and Principles of Sentence Flow), a glossary of grammar terms, an index and, on request, answer keys.
