1、1.在from which 中，which指代的是前面的某个名词或代词。如：The village has only one well from which the villagers draw water.这个村子仅有一口井供村民们取水。2.在from where中，where指代的是前面表地点的介词地点的介词短语，短语，指明具体的地点方位。具体的地点方位。如：He hid himself under the bed,from where he could hear what they were talking about.(from where=and from under the bed

2、)3.一般情况下，where可直接引导定语从句。What is the name of the town where we stayed last night?我们昨晚呆过的那个小镇叫什么？4.但在特定语境中，用where不如用from where。如：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。该句中的from where相当于and from on the top of the hill或from on the

3、 top of which,不可变为from which，但可直接用where引导。不过，语义较为含糊，不如from where生动、形象、具体。where常笼统地表示位置，所含的意义很泛，它可以指“不同方位的介词+地点/位置名词”，这些常见的方位介词有 in,on,by,at,below,under,beside,inside,above,near.等等。We walked for two and a half hours to get therefirst up a mountain to a ridge from where we had fantastic views and then

4、 down a steep path to the valley below.这里介词(from)+关系副词(where)相当于from+地点状语，即关系副词相当于代替前面的一个介词短语，以便所表达地点更加具体，更加清晰准确。A:from which 中的关系代词which只能代替”一个表示地点/事物的名词，不能代替一个介词短语，有时候无法准确表达一个确切地点状语。B:from where 中的关系副词where能代替一个“表示确切地点的介词短语”因此能描述一个比较准确地点状语。这个比较准确地点状语是用来说明定语从句谓语动作发生的地点。（即某人在某地干了某事）定语从句中from where =

5、and from therefrom where =and from there（herehere）从那从那里里since when =and since then since when =and since then 从那时起从那时起She climbed up to the top of the hill,from where she could have a good view of the whole town.(非限制性定语从句）=She climbed up to the top of the hill,and from on the top of the hill she cou

6、ld have a good view of the whole town.（有连词and 连接并列句）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A:and from on the top of the hillB:from on the top of which(which代替先行词the hill)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。He hid himself under the bed,from where he c

7、ould hear what they were talking.(from where=and from under the bed)解析：1 句中的 where 可指为“在床边”“在床上”“在床下”等，意思不够。意思比较模糊）2.句中的 from where 可理解为 from under the bed，意思是“从床下面”,即在定语从句中关系副词where取代/代替了介词短语under the bed）【最后总结】【最后总结】当先行词为：介词+地点名词而不是单个地点名词作先行词时，定语从句需要使用引导词from where 来引导定语从句。(1)from which=from+名词，相当于表达地点比较模糊，不够清楚，尤其是在描述一个准确地点状语时无法达到所需要确切要求。(2)from where=from+介词短语表示从一个（确切且清楚地方位）从而更加更加清楚，清晰，更具体描述定语从句谓语动作发生地点。
