A、His wife. B、His children. C、The Gates foundation. D、Five foundations. D根据句(6)可知，Warren Buffett计划逐渐将公司总股值的大部分捐给五个基金会。因此D为答案。

W: Well, he is the second richest man in the world, but it may not be for long. Billionaire investor Warren Buffett says he is going to give away most of his multibillion dollar fortune to the less fortunate. Now it will be the largest philanthropic gift in history. Buffett is worth about 44 billion dollars and he’s pledged to give away 85% of it. The 75-year old CEO controls Berkshire Hathaway. (6) He plans to gradually give away the bulk of his stock to five foundations. (7) Most of it goes to the Bill & Melinda Gates Foundation, which is focused on ridding the world of malaria, AIDS, and other diseases. So joining us now is a man who knows Buffett and his motivations perhaps better than anyone. Biographer Andrew Kilpatrick. Andrew, good to have you.
M: Thank you.
W: So many people thought that...that Buffett would never give away his money to charity until after he dies. So why the change of heart?
M: Well, that’s right. He...he has always said it would be after he died. He has changed it. (8) I think Gates has influenced him a lot and I think what he sees is the Gates foundation can do a better job of giving than he can. It is really a merger of Buffett and Gates. It’s not a business deal but it’s...it’s two great minds joining together for charity.
W: So that explains perhaps why he gave it to the Bill & Melinda Gates Foundation. I mean, to have the second richest man give his fortune to the richest man in the country might make sense?
M: Well, it’s pretty...it’ pretty funny but he says he’s really not giving it to Bill Gates. He’s giving it through Bill Gates to...to the causes that the foundation deems...deems the best use of the money.
W: Which is already worth, er, something like 30 billion dollars already even without Buffett’s money?
M: Right.
W: So I guess the relationship means a lot to the men then, perhaps.
M: The relationship does mean a lot. They met in 1991. They...they played bridge together, traveled together, went to each other’s football games and homes, and I think they’ve talked about this for a long long time.
W: Well, Andrew, give us the inside story on...on the children’s reaction. (9) I mean Buffett has always said that he was not going to give them his fortune in that he wanna them to have the incentive to work. But I’m wondering, what are their feelings about their dad and his money?
M: (10) They are in full agreement with their father about this. They...they’ve joked about it, saying that is not about what their mother used to think. But they, er, they are in sync with him. In fact, some of the money is going to the children’s foundations, so that they can give it to the causes they believe in.
W: Alright, Andrew. Good to see you.
M: Thank you.
