问题描述：
一道英语从句的题,
The topic,_____ we devoted a full discussion,is to be presented to our teacher at class.
[ ]
A.which
B.where
C.to which
D.for which
说是定语从句,可是定语从句中介词+关系代词不是等于关系副词吗?为什么不能是B?
答
介词+关系代词不等于关系副词
关系副词可以用介词+关系代词来替换
正的可以,反的不一定可以
to which,which 代表topic
we devoted a full discussion to the topic
devote...to
这里to which,to是介词,跟后面的devote是一起的
