Subject：Request for promotion
Dear Mr. Lin，
Since John Liu left the company three months ago, I have been acting as temporary night supervisor. I feel that I have done the job well, and am ready to take on these responsibilities permanently.
I would appreciate your looking over my records, and trust that you will agree that I merit the promotion and associated raise in salary. Thank you for your consideration.
Yours sincerely，
Ivy Huang
亲爱的林先生：
自从约翰·刘3个月前离开公司以来我一直担任临时的夜班主管。我觉得自己干得还不错，并且，我已经为正式地承担起这些职责做好了准备。
我将非常感谢您审阅我的工作记录，并且，我相信您会认为我是值得提拔并获得相应的加薪的。多谢您的关照。
