帮忙译一句话，在线等，急用，谢谢！！！

半开玩笑的口气：您饶了我吧，我知道错了，以后再也不敢了．
to speak with tongue-in-cheek:please forgive me,I know I was wrong,I dare not to do it later.
我保证以后按时完成任务．
I promise to complete my task on time later.

Its just joking (pulling your leg). I know I am wrong. Please forgive me. I wont do it again.

您铙了我吧，我知道错了，以后再也不敢了．我保证以后按时完成任务．
You have forgiven me, I knew mistakenly, later again has not dared. meto guarantee later on time will complete the task.

You Rao had me, I know that wrong, the future no longer dared.

I guarantee that after the completion of tasks on time.

三楼的翻译很好！
