摘要
Chinese lexical items like queshi, zhende, and pianpian represent the speaker’s evaluation of or attitude toward the proposition of the clause in which they appear and form a new proposition together with the at-issue proposition. They are termed evaluative adverbs (EA) even though they do not modify the predicate or the clause in the usual sense. Theoretical and practical considerations for analyzing them as adverbs are discussed with reference to similar cases in other languages, and reasons for treating them as evaluative items are presented with reference to their discourse functions. Examples are given to illustrate their properties and functions, including EA of mirativity, EA of confirmation, and EA of probability. Examples are also selected to show the relationship between EA and expected result, as well as that between EA and refutation. The linear order of EA and other preverbal elements is discussed in detail and evidence is presented that EA is not the same as predicative adjectives. These properties and behaviors are summarized into patterns to serve as the basis for analysis within the framework of cartography of left periphery. EA is assumed to have its own maximal projection Eval(uative)P, which is a layer of Split CP and takes TP as a complement directly or indirectly. The structural relationship of EvalP and other layers of Split CP is discussed as a means to explain the behaviors and interaction of these constituents, including ModEpisP, the maximal projection of epistemic modal; NegP, the maximal projection of negator; and EmphP, the maximal projection of emphatic marker shi.
