语法能力、社会语言能力、语篇能力、策略能力构成了交际能力。语言是文化的载体，又是交际的工具，交际能力必然受到文化因素的影响。尤其在跨文化的交际中，构成交际能力的语法能力、社会语言能力、语篇能力深受文化因素的制约。 Grammar ability, social language ability, discourse ability, strategy ability constitute the communicative competence. Language is the carrier of culture, but also a communicative tool, and communicative competence is bound to be influenced by cultural factors. Especially in intercultural communication, the grammatical competence, social language ability, and textual ability that constitute communicative competence are greatly restricted by cultural factors.
