After long years of indifferent reception by the scientific community, Barbara McClintock's subtle work on the genetics of corn has now been acknowledged to be of major importance; her analyses show that movable elements control the action of genes and thus cause mutations.
A. Barbara McClintock's subtle work on the genetics of corn has now been acknowledged to be of major importance


B. Barbara McClintock's subtle work on the genetics of corn has now been acknowledged as being major


C. it has now been acknowledged that Barbara McClintock's subtle work on the genetics of corn is major in importance


D. there is now acknowledgment of Barbara McClintock's subtle work on the genetics of corn as of major importance


E. the importance of Barbara McClintock's subtle work on the genetics of corn has now been acknowledged to be major


答案是A，我想知道为什么不能选C呢？里面的it可以看成是placeholder吗？

我记得在某个帖子里看见过，being+n的形式一般来说（如果不是描述该名字的characteristics的话），being都是wordy的用法，可以直接排除。acknowledged as 后面应该直接跟名字。

我个人觉得acknowledged as 前后的东西是同等逻辑层次的东西。work been acknowledged as importance 我觉得逻辑意思有问题,work is important 才符合意思

就算是placeholder 逻辑意思也不对。因为after long years ... 的逻辑主语修饰的it，显然不对。
