1. This letter is to inform you that I will require 10 days late-marriage leave in January 20xx for my wedding.
第一句话开门见山，说要请假。英语里请假的最普遍说法是“Leave”。Leave本身是离开的意思，工作中离开就是“请假”。你可以说ask for leave/take leave。比如：I want to ask for leave.
我想请假。Can I take annual leave next week?我下星期能休年假吗?年假是annual leave。这则申请里请的是late-marriage leave-晚婚假。我国现行计划生育政策鼓励晚婚，男年满二十五周岁、女年满二十三周岁的初婚为晚婚。符合晚婚年龄的夫妇，可以在法定三天婚假的基础上增加婚假天数。但是20xx年12月，全国人大常委会审议《人口与计划生育法修正案(草案)》，草案中删除了对晚婚晚育夫妻、独生子女父母进行奖励的规定。来回顾一下这个句子：This letter is to inform you that I will require 10 days late-marriage leave in January 20xx for my wedding.这封信呢是通知您我要求20xx年1月休10天晚婚假。
2. I shall be off to Italy for my honeymoon from 4th January to 14th January.那这句话呢说明了请假期间将去干嘛。要做的事情就是to Italy for my honeymoon-去意大利度蜜月。蜜月就是honeymoon。这句话中还出现了关于请假的另外一个表达，be off，在这句话中表示“离开”，请假还可以说成take+时间+off。I’d like to have three days off.我想请三天假。Can I take one day off?我能请一天假吗? I shall be off to Italy for my honeymoon from 4th January to 14th January.我将去意大利度蜜月，时间是从1月4日到1月14日。
3. I would, therefore, be highly grateful if you could kindly grant my leave for the above stated period.如果您能准假的话我将会非常感谢您。I would ... If...是一个固定句型——如果...就会...，最简单的例句就是I would if I could.我要是能办，我就会办的'。Grateful就是“感激的”，感激某人是be grateful to sb.，为...而感谢是be grateful for sth.。例如：I'm very grateful to you for your help.我非常感谢你的帮助。Ok，grant leave是准假。the above stated period就是说上面所说到的时间段。那么这句话的意思是：如果您能准假的话我将会非常感谢您: I would, therefore, be highly grateful if you could kindly grant my leave for the above stated period.
在今天的节目中，我们学习了如何申请请假，先说明请假的意图，然后表明缘由，最后呢记得要感谢上级。再来回顾一下这则请假条：This letter is to inform you that I will require 10 days late-marriage leave in January 20xx for my wedding. I shall be off to Italy for my honeymoon from 4th January to 14th January. I would, therefore, be highly grateful if you could kindly grant my leave for the above stated period.好了，今天的节目就到这里，感谢收听，再见!
