family in China, I was not used to having two younger kids-Zachary and Grace-running around me yelling(大喊大叫)all the time.

Mom had a serious talk with me about this problem on a Sunday afternoon. She told me, "You can't just come home from school every day, go to your room and do your homework. You need to be a part of this family. You need to play with my kids for at least an hour."This rule was very annoying at first. I did not have much experience playing with children.

However, the more time I spent with the kids, the more I grew to love them. We played games and read books together. I even taught them Chinese. Thanks to Mom's rule, I began to feel like I was really part of the family.

Mom also inspired me to live a healthier life.She got up early every morning to go running. On weekends, she took the whole family to visit parks or go camping.

I did not like sports much when I was back home, but now I love to join all kinds of sports. I am healthier and more confident too.

With my American family, I found joy and laughter. I learned to live with energy and optimism(乐观)，thanks to the care and responsibility of my loving American parents.
