题目

问句子结构i tend to believe that the benefits brought about by this debate override its drawbacks.
问句子结构：
I tend to believe that the benefits brought about by this debate override its drawbacks.
I tend to believe that后面应该是宾语从句,那么the benefits brought about by this debate override its drawbacks中,brought about by this debate 是不是the benefits的定语从句?
如果以上都是理解的对的话,我的问题主要出在：为什么不是：
I tend to believe that the benefits that were bring about by this debate override its drawbacks.

答案

the benefits brought about by this debate override its drawbacks.
这是过去分词做后置定语.
也可以这样表示the benefits which/that are brought about by this debate override its drawbacks
你自己写的句子里 that were bring ……第一个问题是时态,要和主语一致,主语是一般现在,所以没必要用过去式,第二是benefits是 “被……带来的”,所以是be done的被动结构.bring是原型,要换成brought.
所有的这种被动形式的定语从句,都可以省略前面的that/which/who be
如the man （who was） killed by American soldier was a kind teacher.
who was 可以省略.
