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 school without breakfast yet I was late of the first class.When
I entered the classroom, the maths teacher had to stop explaining a important problem, and
all the eyes fixed upon me.My face turned to red.Something even worse happened to me in
the English class.The teacher asked me to recite the text, but I could speak nothing but Sorry,
as I did not spend any time preparing my lessons.The teacher looked at me with his coldly
eyes, I stood at my bench without daring to raise my head.What a terrible day I had! I will
never do anything like this.
