应该是《过去一件有趣的事》英语作文

I am a little ashamed to mention my most embarrasing moment,maybe the most embarrasing moment in my life,that happened approximately one year ago.During that time,I was taking a class in New Oriental in an effort to imporve my english.I was cheerful to learn that the stuffy and arduous class was over soon.When I walked out of the building fifteen minutes later,I was astonished to see that a car had hit a police car!The policeman spoke angrily to the driver and the driver seemed most apologetic.This funny scene really fascinated me,I kept looking at the driver,without realized the danger ahead of me,my head hit hard to a rigid electrical wiring pole.It hurted,I felt my head was in a blank and I crouched down and put my hands around my head.The things made me feel upset were not my head was struck by the electricity wiring pole and the physical pain of my head,the reason I felt upset was a number of people stopped beside me to watch me!No matter what took,I decided to stand up immediately.As long as I standed up,the pedestrains around me would disperse,I thought.Just as I expected,people who watched me walked away in a second when I stood up.I walked slowly with extraordinary pain in my head toward my father's car,which was waiting for me two minutes walk away.
