回答：It has been proved that "已经证明..."
如：It has been proved that what you said just now is right.
现已经证明你刚才所说的话是正确的.
注：it作形式主语,that从句为真正的主语.这句话也可以说成：
That what you said just now is right has been proved.

已经证明。
It has been proved that it is not right to give a child whatever he wants .已经证明孩子要什么就给他什么是不对的。

It has been proved that... 已经证明
It has been proved again and again that whatever the govement---good to our citizens.意思是事实已经证明过多次，政府所做的一切都是为了人民好。呵呵。这个句子是一个填空提里的，里面应该有 does does do 。因为句子比较长所以没用这个的。...
