“只要”表哪种逻辑语义

The Logical Semantic Meaning of "As Long As

这里从语言和逻辑结合的视角 ,通过与“只有”的对比 ,探讨了连词“只要”的表义功能。根据它联结对象的不同 ,划分出两个语用层面 ,即客观事物关系层面和主观构造事物关系层面。“只要”在不同层面的表义功能并不相同 ,在前一个层面中既可表充分条件 ,也可表充分必要条件 ;在后一层面中只能表充分条件。在此基础上 ,还就部分专业书的一些不同观点和用例进行了商榷。

The paper is intended to probe into the semantic function of 'as long as' in comparison with the usage of 'only if' from the angle of language and logic.Based on various linking objects,it is divided into two pragmatic levels,that is,the relation level of objective things and the relation level of subjective constructions.The semantic meaning of 'as long as' differs in these two levels.On the former level it functions both as sufficient condition and as sufficient-necessary condition while on the latter level only as sufficient condition.I wish to discuss with you the different points of view and illustrations on this subject presented in some specialized books.
