THE PROBLEMS STUDIED INCLUDE SUCH GRAMMATICAL CATEGORIES AS ASPECT MARKERS, ADJECTIVES, EXISTENTIAL AND POSSESSIVE VERBS, INDEFINITE PRONOUNS, AND NUMERALS, AND DIFFERENT SIMPLE AS WELL AS SUCH COMPLEX CONSTRUCTIONS AS RESULTATIVE VERBS, THE BA, THE BEI, THE NEGATIVE, THE COMPARATIVE, THE MODIFYING CLAUSE, THE CONJUNCTION OF NP AND OF VBP, AND THE YES-NO QUESTION AND ANSWER. THE PRESENT PAPER IS A BRIEF SURVEY AND DISCUSSION OF THE RESEARCH WORK DONE SO FAR, IN THE LIGHT OF THE MANY ADVANCES IN THE UNDERSTANDING OF THE FORM OF A TRANSFORMATIONAL GRAMMAR, AS RECENTLY SUMMARIZED BY N. CHOMSKY. THIS ARTICLE APPEARS IN THE OHIO STATE UNIVERSITY RESEARCH FOUNDATION PROJECT ON LINGUISTIC ANALYSIS, REPORT NUMBER 10. (IT)
