问题补充：

Many children, parents are away working in big cities, are taken good care of in the village.

A. their

B. of them

C. whose

D. with whom

答案：

A. their

B. of them

(答案→)C. whose

D. with whom

解析：考查定语从句。本题定语从句的先行词是many children,在定语从句中，whose指代先行词作为名词parents定语。句意：很多父母在大城市里工作的孩子在村子里被照顾得很好。AB项不是定语从句，故C正确。
