Having been told the Learning Center provides help for students,Iam anxious to get help from it,
我的疑问是.这里为什么用having been····?可以说being told么?两者有何差别?

Having been told 表示被告知过,强调动作已经发生,并且对现在有影响.
在这里现在分词Having been told 做原因状语,因为having been told（曾经有人告诉我）,所以 I am anxious to get help from it.——我现在才急切想要得到帮助.
being told 只表示过去的一个动作

好好学习下
