Some people may have been daunted by the task because of the difficulties it brings,but I do not know of ________.
A.them doing so
B.any having done so
C.their doing like that
D.any doing that way
为什么?为什么不是选C?

their doing 指“他们做的……事”,为名词词性,结合句子来说明显不通,而A中them指代the difficulties it brings,doing SO指做这个任务,刚刚好.

据我知道的,of后多接宾格,their是形容词性物主代词,不能跟在of后。希望对你有用。
