1) actual comparison
实比
1.
"一样" can express actual comparison or trope,while "不一样" can express only actual comparison;"一样" cannot express the difference in degree while "不一样" can express the difference both in degree and in nature;their adverbial pre-modifiers are also quite different.
“一样”后可以自由地带“X”,“不一样”后只能带表示积极义的单音节度量形容词;“一样”句可以表示实比,也可以表示虚比,而“不一样”句一般只表示实比;“一样”不表示程度差别,而“不一样”则表示程度或性质有差别,所以两者前边能接受的副词类修饰性词语也有很大的不同。
