【正确答案】Sociolinguistics, as an interdisciplinary study of language use, attempts to show the relationship between language and society. More specifically, in this discipline we have two important things to think about: structural things and their uses in a sociocultural context. When we look at sociolinguistics in language classrooms, we are in fact making a choice between training our students as grammarians and training them as active language users. This contrast reflects two different views of philosophy in language teaching. We witnessed a change in language teaching in the middle of the 1970s when Hyme's theory of Communicative Competence was introduced into the field as an antagonism to the traditional philosophy in language teaching. Consequently, as the name of this theory suggested, language teachers began to pay more attention to the question of how to train their students as active and successful language users in a real language context. As far as language teaching is concerned, sociolinguistics is believed to have provided some important contributions which can further be summarized as follows:
(1)Sociolinguistics has contributed to a change of emphasis in the content of language teaching;
(2)it has also contributed to innovations in materials and activities for the classroom;
(3)it has contributed to a fresh look at the nature of language development and use;
(4)it has contributed to a more fruitful research in this field.
