This volume, the first of two, contains 25 units of work; the first 24 units present new material and the last unit is a review. A portion of each unit is presented through programming, that is, information is given in a controlled sequence of steps so that the student may proceed at his or her own rate. Units 1-10 are largely geared to pronunciation instruction, dialog practice and audio-lingual exercises. Units 11-24 continue the pronunciation practice and dialogs, and add different types of practice exercises, especially practice in translation from English to Portuguese. The Portuguese presented in both this volume and Volume Two is educated speech drawn principally from Brazilian sources, but is intended also to serve the needs of students going to Europe or Africa.
