she asked us __A where he lived in B which door could she open C what he was there to do 要详细过程

问题描述:

she asked us __A where he lived in B which door could she open C what he was there to do 要详细过程

选C..
A..因为where本来就表示介词+which..所以不用介意in
B..因为这里是一个宾语从句.用陈述句语序..应该是she could open不是could she open

C what he was there to do
宾语从句要陈述语序,只有这个选项符合

C,A除去in,where本就有在.的意思,B应该为which door she could open
