1.如果report视为动词,则此结构错误.可以是以下两种：
1）have been reporting 现在完成进行时
如：I have been reporting this event for 10 hours,so I feel very tired.
我已经（连续）报道此事件长达10小时之久,所以我感到太累了.
2）have been reported 现在完成时的被动结构
如：These accidents have been reported.
这些事故已经被报道过了.
2.如果report作为名词,此结构是可以的.
如：There have been reports about this conference.
已经有了些关于这次会议的报道.
