We first went up a mountain to a ridge from where we had fantastic views .
问：这个句子中from where we had fantastic views .这个从句是地址状语从句还是定语从句？我记得定语从句中，关系副词where= 介词+which,由于where为关系副词所以其前不可以有介词，所以此句不是定语从句，如果的话就要把where改为which才对，因而此从句应该是地址状语从句，where为表示地址的名词，那样引导地址状语从句的where都是名词，如此觉得对吗？
你比较一下下面的句子：
1 We first went up a mountain to a ridge from where we had fantastic views .
2 We first went up a mountain to a ridge，and from which we had fantastic views .
3 We first went up a mountain to a ridge，and from there we had fantastic views .
4 We first went up a mountain to a ridge，and from it/that we had fantastic views .
1和2 是定语从句，3和4 是对应的并列句。你感觉句3正确还是句4正确？假如你感觉句4错误，句3正确，那样句1就是正确的，句2就是不对的。原句隐含着从大家站着的地方，大家可以看到...。所以定语从句需要用from where , 而不可以用from which. 但用from that place也是正确的。
