Today, I do something stupid because of my carelessness. I take a bus to school every morning. But today, I was on the wrong bus and I realized it ten minutes. I was so nervous when I found it that I shouted loud to the bus driver to stop the bus. I got off on the bus station and took another bus to the school. Of course, I was late for school. When my teacher asked me why I was late, I told her that I got on the wrong bus. She gave me an unbelieving look. In the math class, I was lost in my mind. The teacher named me to answer a question but I didn’t hear him, and I failed to answer it, too. I don’t know what happened to me today. I hope it just because I didn’t have a good sleep last night.

　　今天由于我的粗心，我做了很傻的事。每天早上我都是坐公交车去上学，但是今天，我却上错了车，直到十分钟后我才发现。由于太紧张，我向司机大喊让他停车。我在公车站下车然后上了另一辆车去学校。不出意外的，我迟到了。当老师问我为什么迟到的时候，我告诉她我上错了车，她给了我一个难以置信的表情。数学课上，我开小差了。老师点名叫我回答问题，我甚至没有听见，而我也回答不上他的问题。我不知道自己今天到底怎么了，希望只是因为我昨晚没睡好觉而已吧。
