what's the difference between this text book and the one you used at junior

问题描述:

what's the difference between this text book and the one you used at junior
为什么后面用the one 而不用that来代指前面的text book
不是说that是特指相当于the'+名词
one是泛指,相当于a+名词
但是这道题中,this text book明显是特指啊
跪求高手解答

在这里用that 明显不行,因为 这里是一种比较,所以用the one明显比that 好the size of my shoes is larger than that of yours.这里也是比较,为什么可以用that呢我指的不是比较级的比较,而是两个物体之间的比较
