The fourth edition of this Teacher's Pack is provided as a photocopiable resource and as editable Word files on a CDROM to provide teachers with the flexibility of amending the text to suit the needs of their class. With a scheme of work, lesson plans for each unit, worksheets and ready-made assessments, this Teacher's Pack really enhances the use of the student's book. Supplementary material for use in delivering Units D, E, F and G is also included on the CDROM.
