This is one of a series of books designed to give intermediate students practice in particular areas of English. This workbook takes the learner from the presentation of basic modal meanings through the range of modals appropriate to various functional and notational categories, concluding with a general review section. Each book in the series contains contextualised practice to make it easy to see the meanings which determine the choice of a particular form. A mixture of exercise types is included, focusing both on form and meaning and practice exercises are graded, from items with simple rules to more complex language uses. The material included is suitable for self-study or classroom use. The books also contain well-integrated artwork and a pull-out answer key.
