it's price 和 the price of which的区别
问题描述：
it's price 和 the price of which的区别
Recently I bought an ancient Chinese vase,_______ was very reasonable.
A.which price
B.the price of which
C.its price
D.the price of whose
我知道答案是B,考的是定语从句.但是答案C怎么不行?
类似的还有some of them和some of which; 以及both of them和both of which的区别
比如：We have three foreign teachers,__________are from Canada.（期中的两个）
答案应该是two of whom,而不是 two of them.为什么?
希望英语达人们给出详细的解答.
答
请楼主注意题目两句之间是逗号还是句号,逗号表示句子整体上是一句话,句号表示这是两个独立的句子.你问的属于第一种情况,如果选C则应将中间的逗号改为句号,即Recently I bought an ancient Chinese vase.Its price is very reasonable.注意后一句时态也改了.你问的下面两个例子也是一样.对比之下楼主可以看出,使用定语从句还是比较简练的.
