【正确答案】正确答案：Transformational-generative grammar is proposed by Noam Chomsky. He postulated a syntactic base of language (called deep structure), which consists of a series of phrase-structure rewrite rules, i. e. , a series of (possibly universal) rules that generates the underlying phrase-structure of a sentence. The end result of a transformational-generative grammar is a surface structure that is identical to an actual sentence of a language, after the mediating of a series of rules (called transformations) that act upon the deep structures.
