大家好，今天我們分享一個非常有用且地道的表達——double-cross, 這個短語的含義不是指「雙向交叉」，其正確的含義是：
double-cross 欺騙（幫兇），矇騙（同夥）
The diamond thief double-crossed his partners and gave them only worthless fake jewels.
鑽石大盜欺騙了同夥，給了他們一錢不值的假珠寶。

他承諾不告訴你，但是他卻告訴你了。他矇騙了我。
Don't try and double-cross me, Taylor, because I'll kill you.
泰勒，別試圖矇騙我，因為我會滅了你。
They were frightened of being double-crossed.
他們害怕被矇騙。
double-crosser 騙子，背信棄義的人
I'll make sure that dirty double crosser never works in this town again, if it's the last thing I do.
如果我只能做一件事，我會確保那個骯髒的背信棄義的人永遠不在這個城鎮工作。
