Don't let her catch you breaking the rules; she is likely to go behind your back and complain to the committee about your actions. 不要让她抓住你违反规定的错误; 她很可能在你背后搞小动作向委员会控告你行为不端。
It is settled and therefore we cannot go behind it. 此事已成定局，我们不能再去斟酌它了。
I thought I could trust you to discuss our problems frankly, and not to go behind my back complaining to the manager. 我原为以你会担率地谈谈我们间的问题，不会背着我在经理面前说我坏话的。
