存现句有广义、狭义之分。狭义存现句主要是“有无”句、“某处存在某物”“某物在某处”的句子,而广义存现句则还包括“某处存在、出现、消失某物”的动态句,它们常常表现为“某物在某处V着”或“某物V在某处”的格式。本文以含动词“发生”的单句(以下称为“发生”句)为例,首先判断它是否属于广义存现句,进而对其句法语义进行剖析,并从认知的角度对“发生”句的成因进行分析。 Existential sentence has a broad sense, the narrow sense of the points. The existence of the narrow sense of the sentence is mainly the sentence “” without “, ” Somewhere there is something “” Something somewhere “sentence, but the broad existence of the sentence also includes ” Somewhere exists, there , Disappear something “dynamic sentences, they often appear as ” Something V “or ” Something V somewhere “format. Taking a single sentence (hereinafter ”“ occurrence ”) containing the verb “ occurrence ”as an example, we first determine whether it belongs to the generalized existence clause and then analyze its syntax and semantics. “Occurrence ” sentence causes analysis.
