Question

讲解from where引导引导的一个定语从句。

教材中有类似这样的一句话：
We climbed up a mountain from where we had fantastic views.
“from where we had fantastic views”显然是定语从句（老师也这么说），但我不懂的是，为什么要加一个FROM呢？from在这里可不可以省略了？We climbed up a mountain where we had fantastic views. 不要from好像也讲得通得嘛！·
不一定是这样:We climbed up a mountain，where we had fantastic views.
,可以无.
是按意思理解么？

Answer 1

1、Soon after getting off his horse, the captain appeared at the second storey windows, from where he could see nothing but trees.下马不久，上尉就出现在二楼的窗口了。他从那里除了树木什么也没看到。(引导定语从句)

划线部分相当于…, and from at the windows…不可变为from which…，可用where，但不如用from where更具体。

2、She climbed up to the top of the hill, from where she could have a good view of the whole town.她登上山顶，从那里她可以一览全城风光。（引导定语从句）

划线部分相当于…, and from on the top of the hill或from on the top of which…,不可变为from which，也可直接用where引导，但语义较为含糊，不如用from where更加生动、形象、具体。

3、We went up to the roof , from where we had a good view of the procession.我们爬到屋顶，在那儿我们可以一览整个行进队伍。（引导定语从句）

划线部分可理解为and from on the top of the roof或from on the top of which，用from which是不对的，直接用where仍显不具体，不形象。

Answer 2

1.from这里是表示方向感的，表示登高而远望的意思，如果没有了这个from，就没有这种感觉了。
2.如果去掉from的话，最好是这样写：We climbed up a mountain，where we had fantastic views.

Answer 3

这个句子应该理解为：We climbed up a mountain from on top of which we had fantastic views.
不是从山看到美妙的风景，而是从山顶上看到美妙的风景。
同样，你改后那个句子--We climbed up a mountain，where we had fantastic views--意思就会变成“我们爬上了一座山，在山上我们看到了美妙的风景。”意思就跟原句不一样了！

再给你举个例子：He rushed out from behind the tree.
如果把这个behind去掉，意思不就不对了吗？
