求分析who would have predicted that within ten years he would be in charge of the whole company?求讲解句子的准确意思,主要是时态,he would be in charge of the whole company表示他将要负责整个公司（现在还没有）?是对未来的预测吗还有前面who would have predicted ,这是个什么结构,改成一般疑问句和陈述句该怎么说?

would、should等等+have 表示之前应该这样，却没有这样，这个句子是，他本应预测到他怎么怎么样。

当初谁能预料到不出十年他就掌管了整个公司呢？
整句是虚拟语气，所以用would have predicted.
would表示在过去预测将来的事情。这句既然用了虚拟，表示当初是错的，现在和当初的预测相反。也就是表示他负责公司已经是事实，但是当时谁都没想到。
如果不虚拟:
Nobody predicted in the past that he would be in charge of the whole company.

1、句子结构和成分划分：
【Who 特殊疑问词,主语】【would have predicted谓语】【 that within ten years he would be in charge of the whole company宾语从句】?
【within ten years 时间状语】【he从句主语】【 would be in charge of 谓语】【the whole company宾语】
2、这个句子,实质属于【与过去事实相反的虚拟语气】,主句使用 【would have predicted】.
整体句子相当于：
Who would have predicted that within ten years he would be in charge of the whole company【 if someone/people had predicted about it】?
句子意思：
如果有人当时做过预测的话,谁会预测到在十年之内,他掌管整个公司?
实际表达的意思：
经过十年的时间,他现在已经掌管整个公司,但这在当时没有人预料到.
3、改成一般疑问句和陈述句
一般疑问句
Did anyone predict within ten years he would be in charge of the whole company?
or
Would anyone have predicted that within ten years he would be in charge of the whole company?
陈述句
No one predicted that within ten years he would be in charge of the whole company.
祝你开心如意!

这个其实属于虚拟语气。
相当于：
who would have predicted that within ten years he would be in charge of the whole company ( if people had predicted so)?
（假如当时人们已经这样预测的话，）谁会预测十年内他会负责整个公司呢？
陈述句people would have predicted that...
这里就是people划线提问
一般疑问句：
Would people have predicted that...?
