he has donated most of his money to（ the poor）.(对划线部分提问） To（

To（whom）（has）he donated most of his money?
再问： 具体解释一下，谢谢
再答： 题目的要求是: 对 the poor提问. the poor在句中作介词的宾语,本来用who或whom都可. Who/Whom has he donated most of his money to ? 但你给的格式是: To在句首, 那么在介词后作介宾就只能用宾格,疑问词也是如此, 故用宾格的疑问词whom, 又: 在问句中,助动词has要提到主语前. 因此,变出来的整个问句就成了:To（whom）（has）he donated most of his money? 句意: 他把他的大部分钱捐给谁了?
