英语地点的定语从句,为什么连接词有的用which,有的用where

当先行词在主语中充当主语或谓语时，用which；当先行词在主语中充当地点状语时，用where。

我们也刚学，呵呵。

which是关系代词在定语从句中充当主语或宾语；where 是关系副词在从句中充当状语for example
The park which we visited yesterday is very beautiful.(宾语）
Hangzhou is a city which has a beautiful lake.(主语)
Hangzhou is a city where there is a beautiful lake.(状语）

你要注意，有which 的地方前面一定有介词跟随，像“in which"

首先先看此从句修饰哪个词，此词若在主句中做宾语，用which，若做地点壮语，用where
