先不说例子的语法问题,先说时态.正确的是have you seen和have you been seen.二者都是现在完成时have done,过去完成时应当用had done.seen（“看见”）和been seen（“被看见”）都是done的部分；只不过been seen是被动语态,“被看见”,那么,可以说been帮助seen完成一个被动语态的表达.
Have you cleaned your room?你已经打扫你的房间了吗?
Have your room been cleaned by you?你的房间已经被你打扫了吗?
两句表达的意思一样,但是第二句的被动语态.
简化一下,用一般过去时或许能更明显一点地呈现被动语态：
Did you clean your room?
Was your room cleaned by you?
第一句you做主语,所以用疑问助词did提问；第二句your room做主语,是“被打扫”,所以要用was cleaned,was提前.
这是很长的语法问题,建议你先心平气和地将被动语态弄清楚了之后,再套上现在完成时即可.
