　　The classic text for intermediate through advanced students provides a clear, visual presentation of grammar in terms easily understandable to students. Grammar explanations teach situation ally appropriate English, both formal and colloquial and make distinctions between British and American usage. Each presentation is followed by graded activities that promote speaking, listening, and writing skills. The revised edition features an improved organization, expansion and/or clarification of grammar points, more illustrations, and new excursuses. It is now available in split editions with accompanying workbooks and teacher's manuals for increased flexibility and ease of use.
