Two of the most important people I know are my coaches. They also happen to 小题1: my mom and dad!

My mom, Mary, and my dad, Jack, are my coaches. They started teaching me 小题2: to play tennis when I was only four years old. They gave me the confidence to believe in my game on the court(球场), and to believe that I can do 小题3: I try in my life.

  小题4: most important lesson mom and dad taught me was to enjoy the game while working hard. They said that if I didn’t love tennis, I should find something I did love and give 小题5: 100%. Luckily, they taught tennis in a way that made me love the game. I hope one day to become as great a teacher to others as they have been to me!
