通过自建小型商务邮件语料库,运用Brown和Levinson倡导的积极和消极礼貌策略,探讨英语本族语者和非英语本族语者商务邮件中礼貌策略的使用,结果发现:非本族语者较本族语者来说较多地使用了礼貌策略,特别是积极礼貌策略运用更为频繁。此外,在运用不同的礼貌策略时考虑到社会地位的差异,尤其是选择问候语时常常采用积极礼貌策略来降低面子威胁的程度。 Through the self-built small business mail corpus and using the positive and negative politeness strategies advocated by Brown and Levinson, this paper explores the use of politeness strategies in business emails between English native speakers and non-native speakers. The results show that non-native speakers Native speakers tend to use more politeness strategies, especially positive politeness strategies. In addition, differences in social status are taken into account when using different politeness strategies, and in particular, greetings are often used to reduce the threat of face due to positive politeness.
