从逻辑语义学、词汇语义学、事件语义学的角度来看,现代汉语“又”字的语义除了表示相继、重复以外,还表示“状态恢复”之义。“又”字的这些意义与其所出现的句法环境以及时间有关,并且“又”字的取值对全句的真值起着决定作用,这样“又”字就成为句子算子,它的真值条件和逻辑式可以进行形式化描写。 From the perspectives of logical semantics, lexical semantics and event semantics, the semantics of modern Chinese “” also indicate the meaning of “state recovery ” in addition to expressing succession and repetition. These meanings of the “” characters are related to the syntactic environment and the time they occur, and the value of the word “” also plays a decisive role in the true value of the whole sentence, so that the word “又” becomes a sentence Operator, its truth conditions and logic can be formalized description.
