The color of his jacket is better than mine.改错

针对上文的 his jacket,名词性物主代词 mine 相当于 “形容词性物主代词 + 名词” 的 my jacket.这个句子是 “他的夹克颜色（the colourof his jacket）” 和 “我的夹克颜色（the colour of my jacket = the colourof mine）” 之间的比较,而不是 his jacket 和 mine（= my jacket）相比,所以比较对象不对,需要改为——


The colour of his jacket is better than the colour of mine. 他的夹克颜色比我的夹克颜色好.


为避免用词重复,后一个 the colour也可以用 that 指代——


The colour of his jacket is better than that of mine. 他的夹克颜色比我的好.

改为than that of mine= than the color of mine

His jacket`s color is better than mine.

The color of his jacket is better than that of mine
