在日常的学习和工作中，英语请假条是一种常见的书面沟通方式，尤其在国际化的学校或企业中更为普遍。它不仅体现了个人的礼貌与尊重，也反映了对工作或学习安排的重视。

一份标准的英语请假条通常包括以下几个部分：

1. 称呼：如“Dear [Manager/Teacher]”或“Hello [Name]”，根据对象的不同进行调整。

2. 请假原因：简明扼要地说明请假的理由，例如身体不适、家庭事务、个人紧急情况等。

3. 请假时间：明确写出请假的起止日期和时间段，以便对方安排工作或课程。

4. 表达歉意：对因此带来的不便表示歉意，并表明会尽量减少影响。

5. 请求批准：礼貌地请求对方批准请假申请。

6. 结尾敬语：如“Best regards”、“Sincerely”或“Thank you”等。

以下是一篇原创的英语请假条范文，内容简洁、真实，适合用于日常使用：
