They have been married for 5 years.这个句子为什么要用被动语态.还要5年前面为什么用介词for!

这不是被动语态,实际是be married,是be动词+形容词作表语；
变成现在完成时,所以成了have been married 2.长达多少年,用for这个介词,表示一段时间,for 5 five years

再问：就是看不懂have been married 麻烦解释详细点。been是be 的过去式吗？
再答：某人结婚了，翻译成sb is married，这里的married是个形容词，意思就是结婚了的；所以他们结婚了，翻译成：they are married；而他们已经结婚了，就变成have done的形式，are的done形式就是been；所以就是 they have been married

They have been married for 5 years.这个句子为什么要用被动语态.还要5年前面为什么用介 They have been married for 20 years.为什么要用被动语态呢? 他们结婚十年了 They have been married for ten years 为什么要用have been we've been married for many years 为什么用been married啊?是表达完成式被动 1.They have been married for three years.是完成时的被动语态吗? They have married for 10 years.这个为什么错了, they have been married for fifty years he has been married for six years.为什么用has been married 而不用ha he has been married for three years 句中has been married 是被动语态 they said they have been married for ten years have been married 是被动语态吗 they have been married for ten years=it____________
