that of的用法

(1)that of代替了前面的某個(gè)內(nèi)容

The size of China is bigger than that of USA.(that of = the size of)

(2)that of指代“那一類”

His manner was that of someone accustomed to mixing with nobles.

(他的言行舉止屬于那種習(xí)慣于跟貴族打交道的人。)

(3)that用于強(qiáng)調(diào)上文提到過的詞或短語表達(dá)的同類意思，thatof…的意思是“…的同類的那種東西/事情”。

thatof不能省略,否則后面的名詞短語，就成了前面名詞短語的同位語,也就是說前者是后者的具體解釋,二者是同一種東西的不同說法.但是原文指的是前者是一種東西,而后者是與前者同類的另一種東西。
