Question

你对that 的解释是有误的，它表示的不是一类，而是特指。可数时用the one 替代

Answer 1

一、作为代词的 that，可以用来指代各种情况——
1. 用于指代所指、暗示、提及或被理解的事物，如：：
* What kind of soup is that? 那是什么汤?
2. 用于指代所跟随的某物、某事或某类型，如：
* The relics found were those of an earlier time. 所发现的遗迹是较早的年代。
3. 用于指代已提过的事件、行为或时间，如：
* After that, he became a recluse. 从那以后，他成了隐士。
4. 用于指示较远的或不是很近的一个，如：
* That is for sale; this is not. 那个是出售的；这个不是。
5. 用于强调先前表达过的词或短语的意思：
*He was fed up, and that to a great degree. 他已吃饱，而且相当撑。
6. 用于指代相同的种类的或一类事物，如：
* She followed the calling of that she loved. 她寻着她所爱之人的呼唤。
二、我不记得在什么地方曾经解释过你所指的这个“一类”，准确的说是“相同的一类”，其实就是上面说的第6种，目的是为了避免用词重复。这种用法很普遍，如：
* The weather in Beijing is cooler in autumn than that in Shanghai. (that 指代在上海与北京同类的 weather 。等于The weather in Beijing is cooler in autumn than the weather in Shanghai.)
* She followed the calling of that she loved. （that 与上文 calling 同类的calling。等于 She followed the calling of the calling she loved.）
* The size of these shoes is the same as that of those. (that 指代与上文中同类的 the size。等于 The size of these shoes is the same as the size of those shoes.)
