地点状语从句

题目

地点状语从句
It is a beautiful city ______ I spent many happy hours there with
my friend.
A.where B.in which C.that D.because
老师说答案是D,好像是因为there作从句的主语,不能选AB,我听不懂,

答案

如果选择A,句子就应该成为It is a beautiful city where I spent many happy hours with my friend.
where引导定语从句修饰city,从句中就不能再出现there这样指代地点的名词
因为 I spent many happy hours in this beautiful city with my friend.
B是同理,因为where=in which
