问题补充：

The man, so badly, almost lost his memory and even was driven mad.

A. To have been disturbed

B. Having been disturbed

C. To be disturbed

D. Being disturbed

答案：

A. To have been disturbed

(答案→)B. Having been disturbed

C. To be disturbed

D. Being disturbed

解析：由句子结构分析，此处应为现在分词短语作状语，排除A、C两项，又知the man与disturb之间为被动关系，且disturb动作发生在主句谓语动词之前，故用现在分词的完成被动式having been disturbed.
