如何辨别where引导的是名词性从句还是状语从句还是定语从句

如何辨别where引导的是名词性从句还是状语从句还是定语从句
比如
The church was built( )a Roman temple had dnce been locate.
为什么是where而不是in which
再比如
-When and where you get to know her?
-It was on the farm( )we visited.
为什么是which而不是where

请大家详细说明一下 谢谢

判断是否定语从句，要看有没有先行词。之所以叫做定语从句，是因为引导词引导的定语从句是作先行词的定语结构的。
-When and where you get to know her?
-It was on the farm( )we visited.
上面这个句子中，which引导定语从句，是修饰先行词farm的。这里不能用where是因为从句缺少宾语，而where不能作宾语（名词结构）。如果该句改为It was on the farm ( ) we meet.这里就可以用where了。
至于第一句The church was built( )a Roman temple had dnce been locate.根据我上面的解释，没有先行词，如果是in which，which指代什么？如果该句改为The church was built on the hill ( ) a Roman temple had dnce been locate.这里就可以用on which了。
