Head idioms

Hello, I am a very interesting and intelligent man. And today, my head and I are going to teach you some English idioms. (I'll bet???) you have never been told by my head before. Well, yes, I suppose actually you have been told by my head before. Anyway, now, as we all know, learning a foreign language is very very very difficult and frustrating experience. Yes, indeed, it can very very very very very difficult and frustrating experience. It's like banging your head against a brick wall. In English if we try to do something that seems impossible or make us frustrated, we can say it is banging your head against a brick wall. It's like a banging your head against a brick wall. Of course, with my lessons, learning English is easy. Oh, yes. When you got such an interesting and intelligent teacher as me, it's ..very simple. When do you mean I've got my head in the clouds? In English, if someone is not fully aware of a situation, we can say 'he has got his head in the clouds'. He has got his head in the clouds. Have you met my younger brother? Now I know what you are thinking. You are thinking 'you are a silly man!' . That's not your yonger brother, that's an old man. But you are wrong. He has got an old head on young shoulders. In English, if someone seems old than they are, or if they talk and think like an old person, we can say 'he has got an old head on young shoulders'. He has got an old head on young shoulders. Unlike me, I have got a young head on old shoulders.

各位！我是一個非常風趣而且聰穎的人。今天，我的頭和我將教給你­們一些英語習慣語。我敢打賭你們從未聽過我的頭告訴事情。嗯，也­許，我猜你實際上已經聽過我的頭告訴過你事情。好了，不管了。大­家都知道，學習一門外語是非常非常困難和令人沮喪的經歷，確實如­此。就好像是banging your head against a brick wall。在英語裡，如果我們嘗試做的事情是不可能或者令我們沮­喪，我們可以說it's like banging your head against a brick wall。當然，通過我的課程學習英語是一件容易的事情。如果有­想我一位風趣又聰穎的教師，學習英語簡直是...簡單。你是什麼­意思呀，什麼I have got my head in the clouds呀？ 英語中，如果某人對其所處環境懵懵懂懂，我們可以說he has got his head in the clouds。你見過我的弟弟嗎？我現在知道你們在想什麼，“你­這個蠢貨，那個不是他的弟弟，那是個老人家”！但是，你錯了。'­he has got an old head on young shoulders'。英語中，如果某人看似大過實際年紀，或者­他們的談吐和思考像成熟人那樣，我們就可以說'he has got an old head on young shoulders'。小姐們，小姐們，算了吧。我就不同了，I have got a young head on old shoulders。
