介词＋what\介词＋关系代词要怎么分析啊?我知道前面是宾语从句,是现行词必须是动词么?
请据一例,

答案

1.介词+what 结构有两种理解:
1).介词+what+不定式 后者是疑问词+不定式结构,该结构在本质上相当于一个名词(短语),充当介词的宾语.
如:I'm interested in what to do with this dog.
我对该怎样处置这条狗很感兴趣.
2).介词+what引导的宾语从句
如:I'm interested in what you will do with this dog.
2.介词+关系代词(what不能做关系代词,一般是which/whom,不能用that或who)引导一个定语从句.
关系代词一般代指先行词,在该定语从句中充当这个介词的宾语.
介词+关系代词经常可以转换成关系副词.
如:This is the city in which I lived last year.
=This is the city where I lived last year.
