中文摘要：

文章尝试用“差点儿”中隐性否定的语义溢出，来解释“差点儿没（有）VP”格式中冗余否定的形成机制；用句式的“肯定VS．否定”和其中VP的“积极VS．消极”的配置方式，来推导整个句式评价意义的“正面VS．反面”（庆幸VS．遗憾）；进而用“乐观原则”来解释“差点儿VP”格式三缺一格局的语用动因，以便用句式缺位来说明“差点儿VP”格式中隐性否定的语义溢出的条件。文章还基于对真实文本中400多个“差点儿VP”实例的分析和统计，说明在语言运用层面的语法中，对于歧义句式“差点儿没（有）VP”、甚至所有的“差点儿VP”格式，语言使用者都有可能采用概率性的处理策略，来自上而下地获取其语义解释。文章还指出，“差点儿（没有）VP”格式的使用受到社会道义的约束，这保证了概率语法的实施。

英文摘要：

This paper firstly proposes that the notion of semantic overflow of the implicit negation hidden in the adverb chadianer（nearly） may shed some new light on the puzzle of the redundant negation in the construction ＂chadianer ＋ mei（you）（没有） ＋ VP＂. It then argues that the sentential evaluation meaning （positive vs. negative） of the construction ＂chadianer ＋ （meiyou）（没有） VP＂ could be derived from the disposition of the related grammatical factors in the construction, such as the mode polarity of the construction （positive vs. negative） and the evaluation meaning of the VP itself in the construction （positive vs. negative）. It further explains the pragmatic motivation of the paradigm of the variants of the construction ＂chadianer ＋ （meiyou）（没有） VP＂ by using the Pollyanna principle, and specifies the semantic overflow condition of the implicit negation in the construction with the conception of the paradigmatic gap of the construction. By statistically analyzing more than 400 examples of the construction ＂chadianer ＋ （meiyou）（没有） VP＂, which are retrieved from the real texts, the paper finally demonstrates that people may use a probabilistic strategy in the performance level for processing the ambiguous construction ＂chadianer ＋ mei（you）（没有） ＋ VP＂, even all the constructions of ＂chadianer ＋ （meiyou）（没有） VP＂, and reveals that such construction is applied under the deontic constraint.
