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車去上學，但是今天，我卻上錯了車，直到十分鐘后我才發現。由于太緊張，我向司機大喊讓他停車。我在公車站下車然后上了另一輛車去學校。不出意外的，我遲到了。當老師問我為什么遲到的時候，我告訴她我上錯了車，她給了我一個難以置信的表情。數學課上，我開小差了。老師點名叫我回答問題，我甚至沒有聽見，而我也回答不上他的問題。我不知道自己今天到底怎么了，希望只是因為我昨晚沒睡好覺而已吧。
