what we have said has made her so unhappy.与what have we said to make her so unhappy?
what we have said has made her so unhappy.与what have we said to make her so unhappy?
两句均错，应该为：
What we said has made her so unhappy.陈述句，我们所说的让她很不高兴。
What did we say that made her so unhappy?疑问句，我们说什么了让她这么不高兴？
what have we said to make her so unhappy?这里语法错误
应该是What we have said to make her so unhappy.
用makes或made。不能填to make， said to do sth 转成叙述句谓语后接不定式。 陈述句应是we have said what (make)her so happy.意思
一个是陈述句 一个是疑问句 但有一点小错误
第一句的意思是：我们所说的令她很不开心。What we said have made her so unhappy
第二句的意思是：我们说了什么使她很不开心？What did we say that have made her so unhappy?
What have we said to make her so unhappy?这是一个特殊疑问句,如果把句子还原成We have said what _______her so unhappy,显然to make 作结果状语.
What we have said has made her so unhappy.成了主语从句
