bring up的用法
I don’t know the difficulty she has been brought up her son. 中用has been brought up 对吗?

应该改成:
I don't know the difficulty (she has) in brining up her son.
(that )she has 是省略that的定语从句。。。
have difficulty in doing sth...固定用法。。。
我不知道她抚养儿子的困难之处。。。

好象是坐下把

bring up 抚养
不能用被动语态,应该把has been brought up 改为has brought up

不对,不能用been。那是被动
