此题应选“C”.这里要注意“be able to ”是个固定短语“能够”的意思,且not 一般用在动词之前起否定作用,故选“C”请看以下例句：
I bitterly regret that we have not been able to do better.
我们没能做得更好一些,我深感遗憾.
I regret not having worked harder.
我后悔没有更努力地工作.
I regret not listening her advice.
我后悔没有听她的劝告.
I regret not taking his advice.
我后悔没有接受他的劝告.

BC的区别在于not的位置. 正确的用法是C, 把not放在ing分词的前面(不定式的情形也是如此)

B
regret后面接的是动词ing形式，not不能直接接到regret的后面

C not being ablt to help
not 在being前面
其次regret to do sth是感到遗憾
regret doing sth.是感到后悔
这里其实两个意思都说得通，但只有c语法上是对的

我选B
B的not否定的是able to，意思是：我很遗憾未能帮上他们。
C的not否定的是regret，意思是：我不后悔能帮上他们。
