帮我修改一下这篇英语写作
It was an unforgettable experience for me to become a grateful person.When I was sophomore in my high school,as the captain of the basketball team led our class to take part in the school's basketball game.At that time,a key match with arts team in the group.The only one team can advance who was victory.The points of both team in the game are rising very close from the beginning to the end.What moving me is that the cheer team of class cheer for us constantly.After the fierce competition in the overtime,it is a pity that we finally lost one point.Although we lost the game,there are many people support and comfort us after we down.It absolutely touched me.We harvested the unity and moved in the game and it can motivate us a better life.
