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. 不要讓她抓住你違反規定的錯誤; 她很可能在你背後搞小動作向委員會控告你行為不端。
It is settled and therefore we cannot go behind it. 此事已成定局，我們不能再去斟酌它了。
I thought I could trust you to discuss our problems frankly, and not to go behind my back complaining to the manager. 我原為以你會擔率地談談我們間的問題，不會背著我在經理面前說我壞話的。
