变异修辞是有意偏离语言某方面的规范而获得特殊的艺术效果的修辞活动,其理据就是在修辞活动中激发语言使用者采取偏离常规的修辞手段的动因。修辞是基于逻辑而存在的,而偏离常规的逻辑思维更能突显语言表达信息,这就是变异修辞的逻辑理据。理解变异修辞离不开语境,而变异修辞的存在也满足了人们对言语美的一种追求,这就构成了变异修辞的语用理据和美学理据。 Variational rhetoric is a rhetorical activity that intentionally deviates from the norms of a certain aspect of language to obtain special artistic effects. Its motivation is to motivate language users to deviate from conventional rhetorical devices in their rhetorical activities. Rhetoric is based on logic and existence, and deviation from the conventional logical thinking can highlight the language expression of information, which is the logical reason for variation rhetoric. To understand the rhetoric of variation is inseparable from the context, and the existence of variation rhetoric also satisfies people’s pursuit of speech beauty, which constitutes the pragmatic rationale and aesthetic motivation of variation rhetoric.
