本研究运用语料库驱动的多维分析模式,对比探究The Moon and Sixpence傅惟慈译本和徐淳刚译本的风格异同。研究发现,两译本在“诗化/非诗化”“高可读性/低可读性”“弱源语透射/强源语透射”3个风格维度上存在显著差异,而在“规范化”...本研究运用语料库驱动的多维分析模式,对比探究The Moon and Sixpence傅惟慈译本和徐淳刚译本的风格异同。研究发现,两译本在“诗化/非诗化”“高可读性/低可读性”“弱源语透射/强源语透射”3个风格维度上存在显著差异,而在“规范化”维度上则呈现趋同性。各维度的区别性或趋同性特征具体表现为:维度1的人称代词与句段长等、维度2的结构助词“的”与介词等、维度3的量词与数词、维度4的“被”字句与致使性句式。两译本之“异”与译者身份和社会文化语境直接关联,两译本之“同”与操作规范密切相关。研究表明,多维分析模式可有效应用于汉译本风格对比研究。展开更多
我们可能在英语影视剧、文学作品中看到过一个短语叫“once in ablue moon”,这个短语用来描述很少发生的事件或情况,意味着某件事非常罕见,你可能很长时间都遇不到一次。例如,如果一个人偶尔玩一次游戏,你可以说他们“play games once ...我们可能在英语影视剧、文学作品中看到过一个短语叫“once in ablue moon”,这个短语用来描述很少发生的事件或情况,意味着某件事非常罕见,你可能很长时间都遇不到一次。例如,如果一个人偶尔玩一次游戏,你可以说他们“play games once in a blue moon”。展开更多
