【正确答案】Linguistic competence originally comes from Chomsky. It refers to the grammatical knowledge of the ideal language user and has nothing to do with the actual use of language in concrete situations. This concept of linguistic competence has been criticized for being too narrow and presenting a "Garden of Eden View".
To expand the concept of competence, D. H. Hymes proposes communicative competence, which has four components: possibility, feasibility, appropriateness and performance. In Hymes view, the learner acquires knowledge of sentences not only as grammatical but also as appropriate. It stresses the context in which an utterance occurs, which also leads to a concentration on discourse, in Hymes' term linguistic routines—the sequential organization beyond sentences.
