which 引导定语从句修饰前面的groups
不能按照你说的那样分析句子结构,首先抓住主干
In Europe,multi-media groups have been increasingly successful.为句子主干
后面的groups 是前面multi-media groups的同位语,就相当于解释前面的意思；
而group后面which bring together television,radio,newspapers,magazines and publishing houses that work in relation to one another.是定语从句,修饰前面的group.
你看可以不,可以的话,请选为满意答案.希望对你有所帮助,请指出!
