WHAT在定语从句中的考点（新东方课堂笔记总结）（只是大多数情况下的规则，不排除特例啊~）
首先感谢可爱的善善老师
1、    句子1+ vt +what+ 句子2
2、    句子1 +介词+what+句子2
I will buy the book for which you look.
I will look for what you will buy
重点：“介词+which”结构的前面必须为名词，
     “介词+what”结构的前面不能是名词
同例：
It is difference from which……
It is different from what……
3、    使用时，what优先于n.+conjunction。.
例
That that that the boss said is true astonished us.
That what the boss said is true astonished us.
二句优于一句
