I watch TV until 12 o'clock, so I could not go over my lessons. This morning I got up very late that I had to go to school without breakfast in hurry but I was late for the first class. When I entered the classroom, the maths teacher had to stop explain an important problem, and all the eyes fixed upon me. My face turned red. Something even worse was happened to me in English class. The teacher asked me to recite the text, yet I could speak nothing but sorry, for I did not spend any time preparing my lessons. The teacher looked at me with his coldly eyes. I stood at my bench without dare to raise my head. How a terrible day I had! I will never do anything like this.
