本文根据韩国雉岳高中汉语课中“一”的变调教法实际,提出仅就变调规律客观事实的描写是不够的,这使得变调成为一些零散的语言现象,除了死记硬背,难以掌握。但如果引入语音学理论,结合汉语实际,引入平仄相对的对称性概念的话,就会使变调这一现象从看似零散变成统一的规律性特征,便于掌握。 Based on the actual teaching of “one” in the Chinese class at Pheasant High School in South Korea, this paper proposes that it is not enough to describe only the objective facts of the transposition. This makes the transposition into some fragmentary linguistic phenomena. Apart from rote memorization, it is difficult to grasp . However, if the introduction of phonetics theory, combined with the actual Chinese, the introduction of the concept of symmetry flat tone, it will make the phenomenon of change from seemingly scattered into a unified regular features, easy to grasp.
