问题补充：

many times, he still couldn’t understand it.

A. Told

B. Being told

C. Having been told

D. Having told

答案：

A. Told

B. Being told

(答案→)C. Having been told

D. Having told

解析：考查非谓语动词。非谓语动词的逻辑主语要与主句的主语保持一致，he与tell是动宾关系，即他被告知，应该使用过去分词或被动语态，排除D；当非谓语动词表示的动作与主句的动作又先后关系，这时，应该使用非谓语动词的完成时。根据句意可知，他已经被告诉了很多次，但他仍然不理解，故用Having been told，故选C。
