时量补语句中“了_2”的语法功能考释

A Study on the Grammatical Function of "了_2" in Time-Complemented Sentence

在时量补语句中,当谓语动词具有持续性特征时,句末的“了_2”表述了动词的未完成体意义;当谓语动词具有瞬间性特征时,句末的“了_2”表述的则是动词的完成体意义。就时量补语句言,其谓语动词必须是动作动词,时量补语必须表时段,否则,就不是本文所论述的时量补语句,“了_2”的两种体意义也无从表述。

In the time-complemented sentence, when the verb is durative, ＂了2＂ in the end of the sentence expresses the imperfect aspect meaning of the verb. When the verb is moment, it expresses the perfective aspect meaning. As for as the time-complemented sentence is concerned, the predicate verb must express an action, and the complement must be of timescale. Otherwise, it is not the time-complemented sentence which this article narrates, and the two meanings of ＂了2＂ can＇t be conveyed consequently.
