factors and processes determining the temporal properties of sentences

谓语的时体形式和时间特征是决定句子时间属性的重要因素。除此之外，名词所指实体的数量属性和确定性在确定时间属性的过程中也起着决定性的作用。不定名词可以表示无限多的实体，这与谓词的部分体相结合，使句子表示无限多的事件。特别是当谓语的时态是现在时，句子表示在任何可能的时间间隔内发生的事件。

The tense and aspect forms and the temporal characters of predicates are the most important factors to determine the temporal properties of sentences. In addition to them, quantitative properties and definiteness of the entities designated by the nouns play no less decisive roles in the process of determining the temporal property. Indefinite nouns can designate infinite numbers of entities, which, combined with the partial aspect of the predicates, make sentences designate infinite numbers of events. Especially when the tense of the predicate is the present, sentences represent events taking place at any time interval possible.
