A sad thing Last Wndnesday，I met a thing that made me feel innocent and a little angery. In English listening class, the teacher checked our homework. Concidentally, she checked my homework. But I was just a slip of the tongue say 'he' to be 'she'. The teacher said I didn't finish the homework even didn't open the book. So I felt very sad. And she said in front of the class for three times. In fact, I seriously to finish my homework. I saw the video at least seven times. And I wrote the phonetic alphabet to new words. So I felt very grievance. If a teacher make a mistake because of a slip of the tongue, can I say she don't prepare lessons? As a matter of fact, she did. Therefore, I think she is not a good teacher. She judged me self-righteously. Even worse, the classmates also took this to make fun of me. I think the teacher was deeply hurt me. Fortunately, I don't feel sad and angry today. I can't say I hate her, but I will never like her. I learned some form this thing. Firstly, everyone shouldn't be self-rightous. Secendly, I should reduce my mistakes. Thirdly, angry just make myself hurt. In addition, it's important to have a good teacher.
