“你是男人吗？！”，英文怎么说？

Are you a man?

male是形容词指雄性的，男人的！

英语中，to be a man 意思可不是做个人，或者有个人的样子！是指要有个男人的样子！

所以最好还是用man

而且，LZ不是are you man， 应该是are you a man?

male男性 female 女性 单指性别而言
你这里是说那个人缺乏男子汉气概吗？那应该说，Are you a real/ true man?

Are you a man?

This means you are questioning the person does he has the courage and behaviour as a man.

Sometimes you can also say, "Are you man?", such as "Are you man enough to challenge that big guy?"

In this case, using man as an adjective. Not really correct but acceptable in many places.

are you a husband?
are you a male?
前面那个使用于口语～

就不是Are you a male?
