have been married是不是表被动？marry可以用被动吗？

marry这个词没有被动形式，married既可为形容词（已婚的，结婚的），也可为其动词过去式。
have been married是表示现在完成时，比如：Anna and John have been married for 15 years.

marry可以用被动时态.

表示"使结婚,把...嫁出"的意思,通常用被动.
如: He married his daughter to a farmer(他把他的女儿嫁给一个农民。)
The daughter was married to a farmer by his father.
