讲座内容摘要

假设句从逻辑语义关系上，可以划分为六种类型：充分条件假设、必要条件假设、推论假设、说法假设、目的假设和让步假设。假设句能够通过条件焦点化的“隐性真值否定”进行预期推理，表达充分而又必要的双条件（Biconditionals）或条件完美（Conditional Perfection）。在“如果A，那么B，否则C”句式中，双条件则是由假设的充分条件或必要条件，与否定这个充分或必要条件的真值得到的反转必要或充分条件合并而成。在假设句的六种语义类型中，共有三种类型可以形成双条件句：一是部分充分条件假设句；二是反说必要条件假设句；三是限制性目的假设句。总体上这三种双条件假设句有两个共同的允准条件：一是待议条件焦点化引发“隐性真值否定”；二是充分条件和必要条件的排他性统合。

From the logical semantic relationship, hypothetical sentences can be divided into six types: sufficient condition, necessary condition, inference, expression, purpose and concession. It is assumed that sentences can make expected reasoning through "implicit truth negation" with conditional focus, and express sufficient and necessary Biconditionals or Conditional Perfection. In the sentence pattern of "If A, then B, otherwise C", the Biconditionals are the combination of the assumed sufficient condition or necessary condition and the inverted necessary or sufficient condition which denies the truth value of this sufficient or necessary condition. Among the six semantic types of hypothetical sentences, there are generally three types that can form biconditional sentences: one is partially sufficient conditional hypothetical sentences; The second is the counterstatement necessary condition hypothetical sentence; Three is a restrictive purpose hypothesis sentence. Generally speaking, these three kinds of biconditional hypothetical sentences have two common permissible conditions: first, the focus of the condition to be discussed leads to "implicit truth negation"; The second is the exclusive integration of sufficient condition and necessary condition.
