This first volume of the Portuguese Programmatic Course of the Foreign Service Institute is designed to introduce the student to spoken Brazilian Portuguese and contains 25 units. A large part of every unit is programmed. The text is designed for use with special prerecorded tapes and is accompanied by an instructor's manual containing the script of all recorded portions. Many of the recorded exercises do not appear in printed form in the student's book. It is recommended that every student have a "check-out" session with an instructor at regular intervals to assure that he is progressing satisfactorily on his own. Unit 1 introduces the Portuguese nasal vowels. Unit 2 presents new sounds and the first dialogue. Beginning with Unit 3, every unit contains a grammar explanation and grammar drills, in addition to the pronunciation and dialogue work. An "application" section appears at the end of Unit 6 and each subsequent unit. This section summarizes material covered in the unit and reviews material from previous units. The last unit consists of a review of the following: (1) nouns, contractions, adjectives; (2) verbs; (3) the verbs "ser,""estar,""ter," and "ir"; (4) asking questions with question words; and (5) short verbal exchanges. a Portuguese-English vocabulary list concludes the volume.
