What worried the boy most was to visit his father in the hospital.
A.his not being allowed B.his not allowing
C.his not been allowed D.his being not allowed
为什么不选C?哪位大虾可以解释一下为什么不选C

因为was后面要跟的是一个可以充当表语的句子成分,his not being allowed是一个非谓语短语,已经完整可以充当表语,而his not been allowed并没有完整,改成his not having been allowed就对了为什么改成his not having been allowedhaving been是个非谓语动词短语,你自己去查查非谓语
