About three years ago, I felt very lonely. I didn’t like my classmates, my parents or anyone else. My classmates didn’t want to talk with me and my parents were always saying that other kids were better than me. I thought I was the   66  unlucky(不幸运的) person in the world.

One day I had a big fight with one of my classmates. I was so angry that I hit him in the face. Just at that moment, a boy stood up and stopped the fight. He was the monitor(班长) of our class.

After that, he often helped me and we became good   67 . Whenever I got angry or sad, he would help   68 to cool down(冷静). My life began to change because of the boy, my best friend. We   69  a lot of time on interesting days together. As time goes by, I have become happier with people and things. And it seems that people around me have changed, too. My parents don’t shout at me any more. And my classmates become friendly to me.

But now I can’t often see my best friend   70   he is seriously ill and is staying in hospital. How I miss the days when we were together! I hope he will be all right and come back to school soon.
