【题目】Madame Curie, for ____ life had once been very hard, was successful later.
A. whom B. whose C. which D. that
在线课程【答案】A
【解析】
考查定语从句。句意：居里夫人的生活曾经很艰难，但后来成功了。这道题容易受思维定势的影响认为whose life是一个整体，但如果是whose life，则定语从句没有主语了，B错；定语从句的主语应该是life，本句可以改写为：life had once been very hard for her，所以在定语从句中介词for缺少了一个宾语。故选A。
