1.答案:D.
2.
1)此题考查定语从句的关系代词的用法.
2)主句是The house has been taken down and replaced by an office building.
其主语the house被定语从句I grew up ( )所修饰.
关系代词which = 先行词the house,在定语从句中充当介词in的宾语,然后这个介宾短语充当定语从句的地点状语.
3)即定语从句变化如下:
I grew up in which
= I grew up in the house
3.不过,最好是把in which提前到I grew up之前,而且此题楼主打字还有其他错误,如replace其实是replaced.
