问题描述：
It's a pity that theconcert has been cancelled.是被动语态吗?
平常现在完成时什么情况下会加入been ,什么情况下加入 have been 而不是被动语态
答
这个是被动语态加完成时态。
The concert is cancelled.演唱会被取消。
The concert has been cancelled.演唱会已经被取消。
have done
have been done 表被动
have been doing 表状态
答
你好,本句是被动语态.
用了现在完成时的被动语态
have been cancelled
意思是：很遗憾音乐会被取消了.
如果have / has been 后面有过去分词,就是被动语态
如果have / has been 后面没有过去分词,就不是被动语态
例如：
He has been in Beijing for ten days.
这一句就不是被动语态.
