导语：关系副词 where 主要用于修饰表示地点的名词，同时它在定语从句中用作地点状语。下面小编讲解定语从句的引导词where，欢迎参考。
where 为副词，表示地点。在句子中等同于介词加上表示地点的名词的`功能。用where引导从句，修饰表示地点的名词，where之后要加上主谓宾完整的陈述语序。
如：
Do you remember the place where we first met each other?
Do you remember the place at which we first met each other?
你记得我们第一次相遇的地方吗？
The park where we had picnic last weekend is so fascinating.
The park at which we had picnic last weekend is so fascinating.
上周咱们野炊的公园很美。
I can hardly forget the cafe where we went for the first time.
I can hardly forget the cafe to which we went for the first time.(不常用)
我很难忘记咱们第一次去的咖啡馆。
大家可以发现，where前不加介词，这是因为where本身是一个副词，表示地点，前面不加介词。where引导的定语从句修饰句子中所有的名词成分，可以是主语，宾语或者表语。
