为什么用HAS 不用 HAVE
但是PEOPLE也是整体,动词用复数

先换成陈述句=all that can be done has been done
主语=all
定语=that can be done
谓语=has been done(被动)
转换成简单的主句=all has been done
all 作为一个整体,集合名词所以用单数

这样说把all跟可数一起用的时候用复数
All animals have to eat in order to live.

单独使用的时候用单数
So long as he's happy - that's all that matters (= the most important thing).
All (= The only thing) I need is a roof over my head and a decent meal.

再如本例

他也不是复数呀
当然用has
比如 what he love is money
分析all that =what
该句换种说法
has what can be done been done

意思:能做的都做了吗?
all:adj.全部的, 所有的, 整个的
that has been done
that 是指一个整体,所以用单数。

all that = everything
所以是单三形式

all that当一个整体来理解就可以了
