求英语大神指导一下英语句子

to make things credibler, there are not enough e-book concluding professional knowledge for us to use on the net
我不理解there are 后面句子的成分，e-book concluding professional knowledge和enough的关系，什么东西for us、to use？on the net又是怎么回事？

Answer 1

英语思维是先有一个中心词，然后后面的成分来修饰限定前面的中心词。中心词是e-book，后面的congcluding professtional konwledge 是限定词，意思是包含专业知识的电子书，for us,对我们来说，use on the net 在网上用。整个句子的意思是：对我们来说，网络上没有足够的包含专业知识的电子书。

Answer 2

there are not e-books on the net 这个懂吧，最简单的there are句型。
there are not enough e-books for us to use on the net. enough修饰e-books
there are not enough e-books concluding professional knowledge for us to use on the net.
enough、 councluding professional knowledge都是修饰e-books，定语

Answer 3

on the net 地点状语，在网上。
concluding 。。。。 现在分词短语作定语，修饰e-book
enough足够的，形容词作定语，修饰e-book
e-book为什么不加s，你可以问问出题的人。
