Unfortunately, I caught a cold and I felt a headache. This morning I went to see the doctor. He told me to take two days off and have a good rest. Therefore, I would like to know if I could ask for a sick leave of absence from today to tomorrow. The day after tomorrow, I will come back to school. 　　親愛的劉老師： 　　昨天下午，由于天氣炎熱我去游泳了。不幸的是，我感冒了，而且有點頭痛。今天早上我去看醫生了，他要我休息兩天，好好休息。因此，我想知道我可不可以請今明兩天的病假。后天我就可以回學校了。
