“V不定”构式探析

"V不定"是一种动结构式,但在汉语中其具体表现形式还很复杂,构式义也颇为丰富,它是一种多义构式。运用构式语法相关理论可对"V不定"进行更加深入的分析,并获得它各种独立的构式义,还可进一步探寻这些构式义之间的密切关系,以及它们彼此如何继承联接。

“说/保/指/料不定”的词汇化及情态差别

“V不定”基于动力学图式,体现动力在作用者与反作用者之间的互动关系。V是位移义或使不确定义动词时,是结果补语结构(致使结构);V是非位移义或使确定义动词时,是能性述补结构(情态结构)。“说/保/指/料不定”由动力情态义到认识情态义,词汇化演变机制是命题的确定性和句法的变化。四者认识情态义所占比例由高及低,词汇化程度和主观性程度由高及低,命题均具有预期性。不同的是“说不定”色彩不受限,其余三者多是消极的;“说不定”使用最广,除文艺语体,还用于报刊和学术论著。

Preliminary Studies on the Effect of Photoperiod and Temperature on Male Fertility of a Cytoplasmic Male Sterile Line in Wheat

[Objective] The study aimed to reveal the effect of photoperiod and temperature on male fertility of cytoplasmic male sterile line Vtai911289a in wheat and discuss the mechanism of male fertility alteration. [ Method ] The sowing-date tests and designed conditions were conducted during 2003 -2005. [ Result] Fertility of Vtai911289a, could alter under specific photoperiod and temperature conditions. Temperature is one of the main factors influencing male fertility of the male sterile lines. Vtai911289a, showed stable sterility under the condition of the mean of daily temperature at fertility sensitive stage lower than 19℃ and presented partial fertility when the mean of daily temperature at fertility sensitive stage lower than 20 - 22℃. Photoperiod to some extent affects the male fertility of Vtai911289a, long-day condition is helpful for the male fertility of the sterile line. [ Conclusion] The application of photoperiod temperature-sensitive cytoplasmic male sterile line in production has a higher safety than that of temperature sensitive sterile line.
