句子既是最大的语法结构单位,决定一个句子必须要有结构上的“完整性”;也是最小的言语单位,决定一个句子必须要有言语行为上的“可止性”。汉语缺乏显性的小句核心标记,采用“并列”作为优势策略,所以独立小句与非独立小句的区别不明显,因此缺乏显性的结构完整性,在完句上更多地依靠可止性。汉语可止性要素有四大类型:言语行为属性、判断属性、结果属性与框式句要求。 Sentence is not only the largest unit of grammatical structure, it is necessary to have a structural “completeness” in a sentence. It is also the smallest unit of speech, and a sentence must have a “feasible” verbal behavior. Chinese lack of dominant core sentence tag, using “parallel ” as the dominant strategy, so independent clauses and non-independent clause is not obvious, so the lack of explicit structural integrity, more sentences in the sentence Rely on available. There are four main types of Chinese terminative elements: Speech Act Attribute, Judgment Attribute, Result Attribute and Box Sentence.
