It is such an interesting book as we all like very much
定语从句：
定语从句就是用来修饰名词或代词的句子,起到定语的作用,所以叫做定语从句.被修饰的词叫先行词.定语从句不同于单词作定语的情况,它需要放在被修饰的词（即先行词）之后.定语从句一般由关系代词来引导.关系代词必须放在定语从句之首.
因此,这里的先行词是：book.
后面的as we all like very much 修饰book的,我们都非常喜欢的
强调句要强调先行词的话可以这么改：
it is such an interesting book that we all like very much
结果状语主从复合句:
it is such an interesting book that we all like very much.
结果状语从句通常由 so that...,so...that...等引导,放在句尾.结果状语从句一般表示已经发生的事情,故多为过去时态.如：He lost so many bikes that he decided never to buy a new one.(他丢了那么多辆自行车,他决定再也不买新车了.)
