which和where从句中用法区别

一般来说相应的介词+which 就等同于where,如The shool where i studied in my childhood is very beautifui 。其中的where 可以用in which 替换。这是对于定于从句而言的。因为where 前有了先行词 school,如果是状语从句就不可以用in which 替换。如Let me take you where you live。总的来说where引导定语从句即前面有先行词是,一般可以换成介词+which,例如：1。You should make a mark where you have any questions。2。You should make a mark at the place where you have any questions。这两句话意思相同,可1是状语从句,2是定语从句,区别在于1句中没有先行词place,状语从句中where引导的句子做地点状语。记住where引导定语从句时前面是有先行词的,而状语从句where前则没有。状语有时间状语（last year ,yesterday。等等）和地点状语。1句就是地点状语；宾语有动词的宾语和介词的宾语,My parents bought me a computer。我父母给我买了一台电脑。(me是间接宾语,computer是直接宾语) He is playing football now他正在踢足球。（名词football 作宾语）We all like him。（代词him作宾语）清楚了吗?
