写一篇你所见和所闻的亲身经历，英语作文。

An unforgettable experience Everyone has some unforgettable experience. Last term my leg was badly hurt in a football match, and I had to stay in bed for two weeks. While I was worrying about school work at home, my classmate Tom came to help. He told me what the teacher taught in class, and helped me a lot with my math problems. I was deeply moved because he kept teaching me until I returned to school. I was glad that I caught up with my classmates. From then on, we became best friends. I truly understood that a friend in need is a friend in deed.
