it is easy said than done.为什么用done

Question

如题所述

Answer 1

比较一下，其与主语之间的关系，可以确定。
可以这么理解：We say it easy. We do it.即主语应该是动作的承受者。完整的句子可以这样看：
It is easy to be said. It is hard to be done.
It is easy to be said than to be done.
由于是言谚语，所以要求很简洁。就变成了It is easy said than done.

Answer 2

这是省略句，原句应该是it is easy said than it is done.than是连词连接的是两个句子。句子意思是说比做容易，事情是被说被做，故用done本回答被提问者采纳
