March 22nd, Tuesday                     

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