定语从句中先行词是地点用where还是用which

定语从句中先行词是地点用where还是用which

定语从句中先行词是地点，如果关系词在从句中做状语就用where，如果关系词在从句中做主语、宾语或表语就用which。如：
This is the house where I once lived.(where在从句中作状语)
This is the house which I once visited.(which在从句中作宾语)

1 既可以用 which 也可以 用that 如 this is the place that/which i visited  last year .关系代词作从句中的宾语  也可以省略 2 只能用 that 如 this is the most beautiful place that i have ever visited.先行词含最高级 故只能用 that  也是作定从中的宾语 3只能用which 如 the place ,which i visited yesterday,is very beautiful .  因为是非限制性定从 故只能用which 也是作定从中的宾语 4 用where 如 this is the place where i was born. 关系副词where在定从中 作地点状语 等于in which 也就是 in the place
