I have been received your letter 和 I have received your letter有何区别？？

前者是错的，后者是对的。

如果说I have been receivING your letter，就是你送了很多封信，这段时间我都有收到。

如果是I have received your letter，就是我收到了你送的信，可能很久以来就这么一封，或是特指最近收到的一封。

I have been received your letter 是错误用法。收到信应为 I've received your letter，现在完成时。

意思一样:我已经收到你的信了.

第一句用的被动语态,第二句用的主动语态.

但我觉得很少用被动语态来表达这个意思,至少我没见过.一般都用第二句的表达方式.

I have been received your letter 现在完成时被动语态，（
I have received your letter现在完成时态

只有后面的用法,
没有前面那么用的.
更别说什么区别了.
