评价是近年来语言学界一个热门话题,但大多数研究都聚焦在语篇语义及语法层面,很少从语用视角出发探讨语篇中评价的属性及其表达策略。然而,评价研究的哲学渊源和以往评价研究呈现的语用倾向无不体现了评价的语用维度。英语学术书评作为一个特殊的语类充满了评价表达的礼貌性和客观性等策略,充分彰显了语篇评价的语用本质。 Evaluation is a hot topic in the field of linguistics in recent years. However, most of the researches focus on the semantic and grammar aspects of discourse, and seldom discuss the attributes of discourse evaluation and its expressing tactics from the pragmatic perspective. However, the philosophical origins of evaluation research and the pragmatic tendencies presented in previous studies all reflect the pragmatic dimension of evaluation. As a special category, English scholarly book reviews are full of politeness and objectivity in evaluating expression, which fully demonstrates the pragmatic essence of discourse evaluation.
