A complete grammar practice resource for all ages. The book includes all the grammar covered in elementary to lower-intermediate coursebooks, providing further practice in class or at home. The 21 sections may be used in any order, making it suitable for use with any coursebook. Explanations of rules are clear, simple and easy to remember, and real examples show students how rules work and how to avoid common mistakes. Colour illustrations help to explain difficult grammar points and extensive practice activities teach the correct use of grammar. Grammar and vocabulary are practised together in special exercises and comparative units highlight and summarize differences between commonly confused structures. Differences between written and spoken language, and between formal and informal usage, are explained and cross-referencing helps students to see the connections between related topics. Tests at the beginning of each section show the areas which need practice and tests at the end of each section show progress, and highlight areas needing revision. Appendices include a summary of active and passive verb forms, a guide to contractions, notes on the grammar of common words, and lists of prepositional collocations and irregular verbs.
