“近T”结构是由“近”加上表示时间的语素、词、词组构成的结构体 (如近日、近一两天 )。表示时间的词语 ,以说话时间为分界点 ,有的表过去时间 (如昨天、上周四 ) ,有的表未来时间 (如明天、下周四 ) ,有的可表过去也可表未来 (如最近、周四 )。表过去的称作后指的 ,表未来的称作前指的。不论后指的还是前指的 ,它们自身都有方向上的规定性 ,称作有向的。既能指过去又能指未来的 ,它们自身没有方向上的规定性 ,是无向的。“前指、后指、有向、无向”都是时间词语的指向属性。以指向属性为依据 ,“近T”结构可分为两类 :有向后指的和无向的。“近T”结构原本都是有向后指的 ,后来分化为有向后指的和无向的两类。“近T”结构有时会造成歧义 ,导致歧义的原因有两个 ,一是“近”的多义性 ,二是某些“近T”结构的无向性。 “Near T” structure is composed of “near” plus the morpheme, word and phrase that represent time (for example, in recent days, nearly one or two days). The words that represent time are based on the time of speech as the cut-off point, the past time of some tables (eg, yesterday, last Thursday), the future time of some tables (eg, tomorrow, next Thursday), the past and the future As recently as Thursday). Past refers to the latter refers to the future of the table as the former refers to. Regardless of the latter refers to the former means that they themselves have the direction of the provisions of the known as directed. Both can refer to the past and can refer to the future, they do not have the direction of its own regulation, is undirected. “Front, back, direction, undirected” are the attributes of time words. Based on attributes, “near-T” structures fall into two categories: backward and undirected. The “near-T” structure was originally directed backwards and later split into backward and undirected. The structure of “near-T” sometimes leads to ambiguity. There are two reasons leading to ambiguity, one is the ambiguity of “near” and the other is the nondirectional nature of some “near-T” structures.
