“只有”和“只要”的语法意义辨析

Differentiate and Analysis the Grammatical Meaning of "Merely" and "so long as"

本文起因于《现代汉语词典(第5版)》对"只有""只要"意义的全面改动。针对"只有"是表必需条件还是唯一条件和"只要"是表充足条件还是必需条件两个问题展开论证。通过建立逻辑、事实和语法相结合的论证体系,以语法结构能否正确反映逻辑和事实为检验手段,最终将"只有"的语法意义确定为"表示唯一的条件",将"只要"的语法意义确定为"表示充足的条件"。

This entirely modification in 〈 modem Chinese dictionary （5th edition） 〉 regarding to the meaning of “merely” and “so long as” is the origin of this article. It aims to demonstrate two questions： whether “merely” is denoting necessary condition or single condition, and whether “so long as” is indicating sufficient condition or necessary condition. By construction a logic, fact and grammar- integrating demonstrafin system, and by means of proving whether grammar structure is exactly refelcting logic and fact,finally the grammatical meaning of “merely” is defined as “the single condition” , and that of “so long as” is defined as “sufficient condition”.
