“怀疑”句式的构式义为:根据某些前件,推理出一个命题很可能为假。这一语义的另一个侧面是:其矛盾命题很可能为真。这两个语义侧面,在不同的组配关系中被侧显,引申出两个义项:“不很相信”和“有点相信”。前者表达怀疑主体质疑一种旧认识,体现交互主观性;后者表达怀疑主体建构一种新认识,体现主观性。“怀疑”一词两义,满足了说话人经济性的需要,但加重了听话人的理解负担。作为补偿,说话人会调整话语策略,在语篇层面逐渐形成两种词项的共现规律,以帮助听话人理解。交际双方在表达省力和理解省力上的博弈均衡,造就了“怀疑”句式的句法特点。 “Doubt ” The constructive meaning of the sentence is: According to some antecedents, reasoning out a proposition is likely to be false. Another aspect of this semantics is that its contradictory propositions are likely to be true. These two semantic aspects, flanked in different combinations, extend two senses: “Not very sure” and “Somewhat believing.” The former expresses doubts about the subject as a kind of old understanding and reflects the subjectivity of interaction. The latter expresses a new understanding of the subject of doubt and manifests the subjectivity. “Doubt ” two meanings, to meet the speaker’s economic needs, but increased the understanding of the obedient burden. As a compensation, the speaker will adjust the strategy of discourse, and gradually form the co-occurrence law of the two terms at the discourse level to help the listener understand. The two parties have a balanced game in expressing effort and understanding and saving effort, resulting in the syntactic features of the “skeptical” sentence pattern.
