So then what did you do, Mary?
那么然后你做了什么呢，玛丽？
Well, I ran home to get my backpack. But when I got home, I realized I had left my keys in the backpack.
我跑回家取我的书包。但是当我到家时，我意识到我把钥匙放在书包里了。
You're kidding!
你在开玩笑吧！
So I ran back to school without my keys or my backpack. But by the time I got back to school, the bell had rung.
所以我跑回学校，既没拿钥匙也没有书包。但当我回到学校时，校铃响了。
Oh, no!
哦，不啊！
And by the time I walked into class, the teacher had started teaching already. She asked for our homework, but of course I didn't have it.
当我走进教室，老师已经开始上课了。她向我们要作业，当然我没有。
