it's you who give us this oppotunity, thank you Mr Bono, you are the one who has goodness that warns investors from Wall Street。 这了用了两个who，为什么要用who呢?有什么意义吗?
It's you who give us this opportunity. You give us this opportunity 这句话是个强调句 it is +被强调成分+that/who +句子 是你给了我们这次机会 it is Bruce who told us the story. 正常的顺序是 Bruce told us the story
you are the one who has goodness that warns investors from Wall street. 这句是个定语从句 you are the one是主句 后面是从句 在从句中 who 代替的是the one 在句子中做主语 the one 又代替的是you 所以这句话可以变成两句 you are the one you have goodness that warns investors from Wall street.
