这是一道高考题，请高手作答，并给出详细解析。
谢谢！
A.would be B.has been C.had been
D.was 答案是D

D.was It is said that是强调句行,而that省略,因为结果是不变的.所以用was/

that
It is said that
固定用法.

C.had been过去完成时
你注意到，Tmomas Edison后面有它的出生和逝世的时间，也就是他是发明家已经是过去的是了，而且句子中用的是for sixty years，是一段时间，意思是到那时为止已经有60年了，所以用过去完成时

C.had been 我做过，这个是过去完成时用法。因为结果在过去就已经完成，和现在无关。一楼的真搞，It is said that不是这句话用的，该句还原的话是the book said......

过去的过去呀选C

同意一楼的
It is said that是一个固定搭配
