大门口的那个男的想要见你.英译汉,用定语从句,

there's a man at the door who wants to see you.

The man who is at the door wants to meet you.

The man who is in front of the gate would like to see you.
The man who is waiting at the gate would like to see you.
The man who is standing near the gate would like to see you.
更礼貌些:

The gentleman who is in front of the gate would like to see you.
The gentleman who is waiting at the gate would like to see you.
The gentleman who is standing near the gate would like to see you.

The man （who is) in front of the house wants to see you.
'the man (who is )in front of the house'就是定语从句。the man 是先行词。(who is) in front of the house做定语修饰先行词。
望采纳。
