求翻译：我一大早起床,骑着自行车急忙赶往学校.一路上,我没见到其他上学的同学,我以为我迟到了等我到达学校门口,发现大门还关着.门卫告诉我今天是星期天,不上学.是什么意思？

I get up early in the morning, riding bicycles hurried to school., I didn't see other students of the school, I thought I was late, and so I got to the gate of the school, found the door closed. the guard told me that today is Sunday, not in school.
