A.from which
B.from those of
求详解

B
those of Chinese people=the thought patterns of Chinese people.英语中只有两个同类同质的事物才可以进行比较.后面往往用that指代前面所提到的那个单数名词,用those指代前面提到的那个复数名词.如：
The hair of the girl is longer than that of the boy.这个女孩的头发比这个男孩子的头发长.
The legs of the desk are longer than those of the chair.桌子的腿比椅子的腿更长.
你所给的例句前面是西方人的思维模式,后句则不能是中国人,而应当是中国人的思维模式.
