对于英语学习者来说,只掌握其语音语法规则、词汇是远远不够的,还必须熟知英语语用规约,这样才能避免跨文化交际语用失误的产生。本文对语用规约和跨文化交际语用失误进行了阐述,并分析了语用失误的主要原因——英汉文化差异和汉语负迁移影响。 It is not enough for English learners to master only their grammar rules and vocabulary, and they must also be familiar with English pragmatics in order to avoid the pragmatic failure of intercultural communication. This paper elaborates the pragmatic rules and the pragmatic failures of intercultural communication, and analyzes the main causes of pragmatic failure - the cultural differences between English and Chinese and the negative impact of Chinese translation.
