1. I´m in no mood for trifling.
    我无心嬉戏。

2. It is no use inviting the politician or the professional or business man, who has been working or worrying about serious things for six days, to work or worry about trifling things at the weekend.
    同样，对于为严肃的公务操劳或烦恼了6天的政界人士、专业人员、商人来说，在周未再让他们为琐事而动脑子和忧虑也是无益的。
