我明天有事情要做。
    【英文對比翻譯】
    Chinese Style —— I have something to do tomorrow.
    American Style —— I am tied up/busy all day tomorrow.
    【點評】
    用I have something to do來表示你很忙，這是比較中國式的說法。雖然有時我也能聽到老外說。比如有人要你幫忙做某事，可以說I am so sorry that I have something else to do now.因為每時每刻我們都有事情要做，躺在那里睡大覺也是事情。所以你可以說我很忙，脫不開身：I am tied up.還有其他的說法: I can't make it at that time. I'd love to, but I can't, I have to stay at home.
    所以我個人認為這樣拒絕別人會比較委婉禮貌，而不是說I have something to do顯得態(tài)度強硬，不耐煩。
