【正确答案】正确答案：Communicative competence is what a learner knows about how a language is used in particular situations for effective and appropriate communication. Communicative competence includes knowledge of the grammar and vocabulary, knowledge of rules of speaking, knowledge of how to use and respond to different types of speech acts and social conventions, and knowledge of how to use language appropriately. In order to develop communicative competence in our foreign lauguage learning, language learners are encouraged to deal with accomplishing actions, which are believed to help them acquire the target language. Two types of tasks are usually required to be performed by the learners: real-world tasks and pedagogical tasks. For example, students may be asked to work or discuss in groups. Besides, teachers can adopt the communicative syllabus which aims at the learner's communicative competence. It teaches the language needed to express and understand different kinds of functions, and emphasizes the process of communication.
