请问下面句子里的“the concern that”是个什么用法?
The emphasis on the criterion of identifiability arose out of the business combinations project and the c o n ce rn t h a t,in identifying the assets and liablities acquired,the intangible assets acquired must be distinguished from goodwill.

答案

供参考
这句子的基本结构是
主语(emphasis) + 不及物动词(arose) + 介词的两个宾语(project 和 concern)
至於 the concern that 的用法
其实是 由 that 而成的一个名词从句来对 concern的意思加以补充
这个名词从句的基本结构是 that the intangible assets acquired must be distinguished
from goodwill.
而in identifying the assets and liablities acquired 则是由介词短语
