(单选题)

Winston Churchill, ______ life had been tough in school, was glad to seek his fortune in the army.

A.for whom

B.of whom

C.in whom

D.for whose

参考答案：A

参考解析：

考查介词+关系代词的用法。句意：对于温斯顿·丘吉尔来说，学校的生活非常艰难，所以他很高兴到军队里去碰碰运气。分析句子成分可知，______ life had been tough in school充当先行词Winston Churchill的非限制性定语从句，从句中句子成分完整，life严格意义上来说与先行词存在所属关系，可以填入whose life或者of whom the life，选项不符合语境，只能选择for whom，for在此意为“对于”。故选A。
