The units contain authentic reading and listening texts intended to be used as stimulus for discussion. The accompanying cassette provides a wide range of native speaker accents. The teacher's pages provide clear instructions for each activity, as well as providing a wealth of background information on each topic, keys to the activities, complete tapescripts and suggestions for discussion-based writing activities. The material is designed to be flexible and free-standing: activities can either be used as the basis for a discussion course or dipped into in or out of sequence.
