Reward and punishment

赏信───Appreciation letter;罚必───Punishment must be taken

However, it's better to say thank you late than never at all, so don't give up on sending a letter of appreciation later if you feel that this is appropriate.───然而表达感激之情比不表达总要好，所以不要放弃写感谢信，即使你觉得这个时候才写是不合适的。

Mary: I agree. Do you know how to write an appreciation letter?───玛丽 ：或许公司读了你的信之后会雇用你呢。

Jack: Though I failed, I also plan to write an appreciation letter and I think it's very necessary.───杰克：虽然失败了，可我还是打算写一封感谢信。我认为这样做很有必要。
