請假條(written request for leave)是常用應用文之一，用於向老師或上級領導等因身體狀況不好或因某事請求准假的場合。它包括請病假(note for sick leave)和請事假(leave of absence)。
英文請假條寫作需注意三點：
1.寫法和漢語請假條相同，一般由四部分組成，即時間、稱呼、正文和署名。
2.請假條是一種簡單的書信文體，一般寫在紙上，不用信封。
3.要求開門見山、內容簡短、用詞通俗易懂。
【範文例析】

Dear Miss Lu，
I'm sorry I can't go to school today. I played football with my classmates yesterday. Unluckily, I fell off and hurt my leg, but I wasn't badly hurt. The doctor asked me to stay in bed and have a good rest. So I ask for leave for two days.
Many thanks. I'm looking forward to your kind answer.
