关于定语从句的一道选择题求【详解】

They stood on the top of the high building ,______they could see the whole city .
答案是：from where

求详解为什么答案不是from which .

Answer 1

• 本来就选A，楼主疑惑的是不是from the top of the high building?其实不是这里的from, from where 的from是来源于see from，因为有定语从句所以提前到先行词前面，变成现在见到的A选项，原来的顺序是：

　　you could see the whole city from the top of the high building.

　　这个解释可以不?

• 【误】 They stood on the top of the building, from which they could see the whole city. 【正】 They stood on the top of the building, from where they could see the whole city. 【解析】 from where＝from the top of the building，from which＝from the building，显然前者比较合适。

Answer 2

将这句话直译一下，就是【他们站在一座高大建筑的顶端，从那个地方他们可以看见整座城市】
因此where指代的是地方，而which意为哪一个
（ps，相信我，除了固定搭配外，翻译法是最有效的）

追问

我认为此句可以理解为，the top of the building 是先行词吧，而且from which =where 吧？

Answer 3

你可以这样去理解：
from where=from on the top of the high building=from on which

Answer 4

关于from which的用法比较好理解，这里主要说说from where的用法。from where主要有以下两个用法：
用法一：用于引导非限制性定语从句，在意义上相当于 and from there（从那儿）。如：
He hid himself in a tree, from where he could see the enemy in the distance. 他躲在一棵树上，从那儿他可以看到远处的敌人。
We went up to the roof, from where we had a good view of the procession. 我们爬上屋顶，从那儿可以很好地观看游行。
用法二：可视为where前省略了the place，即这样用的from where 相当于from the place where，意思是“从……的地方”“离……的地方”。如：
From where I stood I could see everything clearly. 从我站的地方我一切都看得清清楚楚。
The car stopped short only a few inches from where I stood. 汽车在离我站的地方仅几英寸处突然停住。
The school was only a few blocks from where she lived. 学校离她的住所只有几个街区的距离。
若遇到前面是地点名词的先行词，如何判断用where还是from where还是from which?请看下面一个句子：
I have bought that house, _____I can enjoy the beautiful scene of Yangpu Bridge .
我们认为这道题填 where 和 from where 语法上都可以（但不宜填 from which），但两者在意义上稍有区别：
I have bought that house, where I can enjoy the beautiful scene of Yangpu Bridge. 我买下了那栋房子，在房子那可以欣赏到杨浦大桥的美景。
I have bought that house, from where I can enjoy the beautiful scene of Yangpu Bridge. 我买下了那栋房子，从房子那可以欣赏到杨浦大桥的美景。
在许多情况下，用不用 from 不会导致语法错误，但会导致语义变化（通常情况下是，如果没有 from，意思会不够明确和清楚）。比较：
He hid himself under the bed, from where he could hear what they were talking. 他躲在床下面，他可以从床下听到他们谈话。（句中的 from where 可理解为 from under the bed，意思是“从床下面”）
He hid himself under the bed, where he could hear what they were talking. 他躲在床下面，在床那儿他听到他们谈话。（句中的 where 可指为“在床边”“在床上”“在床下”等，意思不够明确）

刚在网上又找到了一段：
特别是当前面的地点只是一个整体的一个部分时，就只能用from where.

They climbed to the top of the tower, from wherer they could see what was happening in the distance.

where=the top of the building, which=the building
