vwhere 可以引导定语从句，在定语从句中作地点状语。一般来讲是接地点，但有的时候也可以跟不同的情景或状况。如situation,case,conditions等。例如： We should be calm when facing the situation where we are required to made an immediate decision.
要举例子？不如掌握方法。其实where在定语从句里很容易和which搞起来，在这里列举一个八年级牛津课本的例子：One of the most scenic areas is the Loire Valley, where you can visit the old castles in which the kings and queens of France used to live。
这句句子既包含了where也有which，都代地点，那到底区别是什么？再看同一个句子的几种不同表达： This is the house which I was born in。 =This is the house that I was born in。
=This is the house I was born in。 =This is the house in which I was born。 =This is the house where I was born。 可以看出，in which = where，in which中的in也可以放到句子最后。
就是说v+prep+地点时，可以用where，代替的就是prep+地点，如果用which，代替的就只是地点，所以在句中仍要用prep。
答：他们说的并不充分. 的确,在一定程度上,IN WHICH与WHERE是相等的.他们修饰 的先行词是表地点的 例如:The house where I live ...详情>>
