问题补充:
Recently I bought an ancient Chinese knife,was reasonable.
A. which price
B. the price of which
C. its price
D. the price of that
答案:
A. which price
(答案→)B. the price of which
C. its price
D. the price of that
解析:考查定语从句。本题的先行词是knife,关系代词which指代先行词knife作为of的宾语。句意:最近我买了一把中国古代的刀,它的价格很合理。C项不是定语从句。That不能放在爱介词的后面,排除CD。Which不能修饰price.故B正确。
