She's hopelessly headstrong; she always gets up against people in authority. 她剛愎自用到了不可挽救的地步，老是與主管人員發生沖突。
Nobody in authority was available to take advantage of the offer of a reduced price for a bulk order, so I ordered twice our normal requirement on my own initiative. 當時沒有負責的人在場能大批訂購削價貨，因此我主動地訂購了比我們正常需要多兩倍的貨物。
They've (ie The people in authority have) sent us another form to fill in. 上面(負責人)又送來一個表格讓我們填寫。
Who is in authority (ie holds the position of command) now? 現在誰掌權?
