____as the main reason for the recent world-wide economic problems is the fact that the US government would hardly accept.
A.Regarding B.To regard C.Regarded D.Being regarded
还有顺便帮我理一下 having been done ,beind done,done做题的时候怎么区分

这个句子的谓语是is,所以is前面的那些成分要充当主语,本句只能用动名词短语或者不定式短语充当了,据此排除C. 由于主语表达的意思是“被当做本次世界经济问题主要原因的是.”,这里需要用被动含义,所以之选择D.
having been done是现在分词的完成形式,
being done是现在分词的被动形式,强调一个动作正在被做
done则是过去分词,表示动作是被动的而且已经完成
这三个短语侧重点明显不同.
