借代作为一种修辞方式和人类的思维方式为话语交际行为的继续做出了很大的贡献。它不仅对话语输出者和接收者双方在明示—推理过程中提供有力信息,而且在不断添加信息时营造不同认知语境使得话语交际得以继续与拓展。借代既符合关于交际的经济原则,又能够表达说话者的语气和情感,雅化交际内容。在跨文化交流中,借代还能够创造新词,活跃交际氛围,增加语言的活跃性和创造性。 Metonymy as a rhetorical method and human way of thinking for the continuation of the communicative action made a great contribution. It not only provides powerful information to both the discourse exporter and the recipient in the explicit-reasoning process, but also creates different cognitive contexts in the continuous addition of information so that the discourse communication can be continued and expanded. Metonymy meets the economic principle of communication, but also can express the speaker’s tone and emotion, elegant communication content. In intercultural communication, intergenerational can also create new words, active communication atmosphere, increase language activity and creativity.
