A third volume of a highly articulated set of language materials defines achievement level 2 in the control of Spanish syntax while providing descriptions and interrelationships of vital syntactic structures and expected student performance. The noun phrase, predicate phrase, verbal aspects, adverbials, relativization, noun modification, nominalization, "si" clause, interrogatives, comparison, negation, pronouns, imperatives, exclamations, passivization, alternation of basic sentence patterns, deletions, and conjunctions are presented. Selected sentences from current audio-lingual teaching materials are offered in a systematic arrangement providing the student with a segmented learning coutinuum in small units and the teacher with an overview of the structural content. The structuring of syntactic units is based on transformational generative-grammar linguistic principles. Each grouping is presented with an introduction, illustrative examples, and performance tests dealing with auditory comprehension, speaking, reading, and writing. Considerable material is included on objectives of the study, assumptions and hypotheses, and methods and testing. A conclusion, list of references, glossary, tables, and appendixes are included.
