Question

What upset the child was __ to visist his mother in the hospital. A.his not to be allowed

B.him being not allowed C.his not being allowed D.him to be not allowed为何不选B？

Answer 1

选C.his not being allowed
首先排除B.him being not allowed ，not位置不正确，应该在being前面；
这句话意思是：使得这个小孩沮丧的是他不准去医院看望他的妈妈。
What upset the child 是主句主语，因为由一个完整的句子来充当主语，所以是个主语从句，was是主句系动词，his not being allowed to visist his mother in the hospital是主句表语。his是not being allowed to visist his mother in the hospital的定语，是“他的不被允许去医院看望妈妈这件事”，有个领属关系，所以不能用宾格him，类似的说法还有很多，比如：His being succeeful in the game made him popular with students。另外，为什么用现在分词的被动式，而不用不定式的被动式，是因为：不定式表示动作还未发生，将要发生，可是这儿“他没有被允许去医院看望他妈妈”是个事实了已经。
