【正确答案】正确答案：Chomsky's TG grammar has the following features. First, Chomsky defines language as a set of rules or principles. Secondly, Chomsky believes that the aim of linguistics is to produce a generative grammar which captures the tacit knowledge of the native speaker of his language. This concerns the question of learning theory and the question of linguistic universals. Thirdly, Chomsky and his followers are interested in any data that can reveal the native speaker's tacit knowledge. They seldom use what native speakers say; they rely on their own intuition. Fourthly, Chomsky's methodology is hypothesis-deductive, which operates at two levels; (1) The linguist formulates a hypothesis about language structure—a general linguistic theory; this is tested by grammars for particular languages. (2) Each such grammar is a hypothesis on the general linguistic theory. Finally, Chomsky follows rationalism in philosophy and mentalism in psychology.
