选哪个?为什么?

I can't tunderstand _ such a well-paid job.A、him to give up B him to have given upC his giving upD his being given up 选哪个?为什么?
选择：C his giving up
解析：
1.understand 作“理解、谅解”讲时,如果后面用非谓语动词作宾语,和 suggest、finish、not mind 等动词一样,要求跟动名词.
2.由于“放弃酬劳优厚工作的人”不是句子主语 I,因此需要给非谓语动词另外加逻辑主语,这种带有逻辑主语的称作非谓语动词的复合结构.动名词的的复合结构是 one's doing (名词或代词所有格 + 动名词,这一点同用物主代词或名词所有格修饰名词是一个道理),his giving up 正是这种结构.
另注：其它非谓语动词的复合结构如下：
不定式：for sb.to do sth.（for介词短语 + 不定式）
现在分词：one doing sth.（名词或代词主格 + 现在分词）
过去分词：one done （名词或代词主格 + 过去分词）

c

C his giving up动名词的复合结构作宾语。

“放弃”是主动的，所以用现在分词giving up,his做逻辑主语，选C

C,giving动名词，意思是他放弃工作这件事

c
understand sb/sb's doing sth
