I have many bad habits, but there is one always makes me upset. I like nodding off in class. Nearly everyone will have this bad habit in summer. But I will nod off in every class and every season. Usually, I will nod off when the class begins about ten minutes. I hate this. I have tried my best to correct it. But I failed in the end. This habit troubles me lot.
我有很多的壞習慣,但有一個讓我一直都很心煩。我喜歡在課堂上打瞌睡。在夏天幾乎每個人都會有這種壞習慣。但是,一年四季每一堂課我都會在課堂上打瞌睡。通常,開始上課十分鐘左右我就會打瞌睡了。我很討厭這一點。我也曾努力改正過。但最后我還是失敗了。這個習慣讓我很心煩。
