claims to 作什么成分

Sometimes years are required for truly novel discovery claims to be accepted and appreciated.

请问claims to在句子里头作什么成分？

Sometimes（时间状语）// years （主语）//are required（谓语）// for truly novel discovery claims to be accepted and appreciated（不定式复合结构作目的状语）.

参考译文：有时声称真的的新发现需要数年时间才能被同意和被赏析。

句子结构为：A be required for C to be done 意思为“A被需要以便于C被做某事”

for trul novel discovery claims to be accepted and appreciated.

for truly novel discover claims为不定式逻辑主语，与不定式存在逻辑上被动主谓关系。
